Rosen This article examines how competition among lenders affects mortgage loan characteristics. The author finds that, on average, banks issue safer mortgages than independent mortgage banks. Further, mortgages from banks with a branch in the local market where the property is tend to be safer than mortgages from banks without a local branch. Changes in market shares among lender types (local bank, nonlocal bank, or independent mortgage bank) that lead to higher loan risk also are associated with better borrower quality. Increasing the local market share of a lender type raises loan risk and borrower quality at that lender type. 22 Monitoring financial stability: A financial conditions index approach Scott Brave and R. Andrew Butters Monitoring financial stability requires an understanding of both how traditional and evolving financial markets relate to each other and how they relate to economic conditions. This article describes two new indexes of financial conditions that aim to quantify these relationships. Second Quarter 44 Understanding the Great Trade Collapse of 2008-09 and the subsequent trade recovery Meredith A. Crowley and Xi Luo This article documents the Great Trade Collapse of 2008-09, as well as the dramatic recovery in trade of 2009-10. The authors consider how three distinct policy actions—fiscal stimulus, funding for trade finance, and a commitment to refrain from increasing trade barriers—might have affected both the collapse and recovery. 71 How do private firms use credit lines? Sumit Agarwal, Souphala Chomsisengphet, and John C. Driscoll The authors find that firms that face higher upfront commitment fees, risk premium spreads, or usage fees have smaller credit lines, while those with higher overdraft fees have larger ones. Firms with greater profit growth in the past have larger credit lines, while those with more internal funds or higher volatility in profit growth have smaller credit lines. The results for line utilization are quite similar. 80 International Banking Conference The Role of Central Banks in Financial Stability: How Has It Changed? Competition in mortgage markets: The effect of lender type on loan characteristics Richard J. Rosen Introduction and summary The years 1995 through 2007 saw a boom and bust in home prices and purchase activity in the United States. There has been a lot of attention paid to the causes of the boom-bust cycle and who, or what, is to blame.1 Some have blamed the cycle on subprime lending and the securitization of home mortgages (see, for example, Mian and Sufi, 2009; Keys et al., 2010; and Demyanyk and Van Hemert, 2009).2 During the latter years of the boom, both subprime lending and securitization ex panded significantly. By 2005, subprime lending was over six times as large as its pre-2000 peak, and over all securitization was more than twice its pre-2000 peak? But these changes, and the housing cycle in general, were not uniform across the country. The expansion of lending and the subsequent problems in housing mar kets were more extreme in some markets than in others (Mian and Sufi, 2009), in part possibly because of changes in home prices. Home prices rose much more rapidly in some markets than in others, both in percent age terms and relative to fundamentals (see, for example, Haines and Rosen, 2007). Differences across markets may occur because of market conditions and the core attractiveness of a market (see, for example, Gyourko, Mayer, and Sinai, 2006). However, they may also reflect differences in the composition of lenders in par ticular markets. This article explores how the charac teristics of mortgages varied over time and across markets and how these differences relate to the com position of lenders in the markets.4 The characteristics 1 focus on are measures of loan risk and borrower qual ity. 1 examine how these differ across mortgages issued by different types of lenders and how shifts in mortgage shares among lender types in local markets affected standards of lenders in those markets.5 I focus on the lender that originates, or originally funds, a mortgage. The primary division of lenders is into banks (that is, depository institutions) and 2 independent mortgage banks (IMBs). Banks and IMBs differ in corporate strategy and regulation, both of which may affect their approach to participating in mortgage lending, including the characteristics of the mortgages they issue and the borrowers they issue them to. Mortgage lending generally plays a much larger role at IMBs than at banks; unlike IMBs, many banks tend to view mortgages as just one part of a broader strategy. Banks typically have branch networks to attract deposit customers, and mortgages may form only a part of their asset portfolios. In part because the presence of branches can affect the way banks com pete for mortgage borrowers, I subdivide banks by whether or not they have branches in the local market being considered (local banks versus nonlocal banks). Local banks may be able to use their branches’ pres ence to help them capture potential borrowers. Over the past 15 years, the market shares of the three types of lenders (local banks, nonlocal banks, and IMBs) have shifted by as much as 15 percentage points. From 1995 through mid-2006, the share of mortgages made by local banks trended down. Initially, local banks lost market share to IMBs, but starting in 2001, mortgages issued by nonlocal banks began to make up a large share of total mortgages in many markets. Finally, there was a massive readjustment away from mortgages made by IMBs starting in mid-2006, slightly after the housing market bust had begun.6 The way I divide lenders in this article reflects important differences across lenders in the mortgage delivery process. How borrowers are matched with lenders and how mortgages are ultimately financed Richard J. Rosen is a senior economist and economic advisor in the Economic Research Department at the Federal Reserve Bank ofChicago. He thanks GeneAmromin and Anna Paulson for their comments and Robert McMenamin and Edward Zhongfor their assistance with the research. 1Q/2011, Economic Perspectives (two key elements) typically differ across the three types of lenders I focus on. A potential borrower wanting a mortgage has the option of contacting a bank or IMB directly. For example, a borrower who wants to find out about lending terms and conditions could visit local bank branches and talk with a loan officer. Alterna tively, the borrower could use the services of a mort gage broker. A mortgage broker is an independent agent who serves as a contact between borrowers and lenders, arranging loans but not actually lending money. The broker can offer borrowers a menu of loan products from different lenders.7 According to one study, mort gage brokers helped arrange 68 percent of all residen tial mortgages in 2004.8 Brokers make it easier and less expensive for lenders with no physical presence in a market to lend in the market. This can potentially help both banks and IMBs expand. Often, the use of brokers is referred to as wholesale lending (as opposed to retail lending, where originators connect directly with borrow ers, often when customers visit a bank branch or have a pre-existing relationship with the lender).9 The expec tation is that most IMBs and nonlocal banks operate in the wholesale lending market, while local banks rely on a mix of retail and wholesale lending (although, clearly, there are variations in strategy across banks of the same type). As noted previously, many loans are securitized. Traditionally, the primary option for a potential home purchaser who needed a loan was to go to a local bank. Typically, the bank would hold the loan in its asset port folio, financing it using its own deposits. This put a natural limit on the ability of the bank to issue mort gages. In the securitization process, the bank or other lender that initially funds the loan quickly sells it to a third party. The third party then uses a pool of mort gages as the collateral backing a bond issue. The bonds, known as mortgage-backed securities, are sold to in vestors (see Rosen, 2007b). The ability to easily sell mortgages means that the originating lender can finance a larger volume of loans with its capital. The costs and risks of originating mortgages for lenders that plan to securitize them are different than for lenders that plan to keep the loans in their portfolios. This difference may affect how the lenders compete for borrowers. While securitization made it easier for all lenders to expand, it is likely to be more important for those lenders with out a strong deposit base, especially IMBs. The ties between mortgage brokerage and securi tization, on the one hand, and lender competition and lending market standards, on the other hand, are both direct and indirect. The presence of mortgage brokers, at least those who act in the interests of the home buyers (see note 7), should increase the competitiveness of Federal Reserve Bank of Chicago lenders. This could mean lower mortgage rates, but it also could mean that other mortgage terms are relaxed, such as allowing applicants to take out larger mortgages than their incomes might readily support or mortgages that are significantly higher than the value of the homes they are buying. It is plausible that increased compe tition among lenders contributed to such developments as the 125 percent loan-to-value mortgages offered during the housing boom. Securitization also can in crease the competition for mortgages. The expansion of securitization in the 1990s and the early part of the 2000s meant that the risk that a lender would not be able to sell a loan was reduced; also, the time a lender was forced to hold the loan before selling it as part of the securitization process likely fell. This made it less risky, and therefore less expensive, for lenders to enter new markets and expand. However, securitization also benefits from economies of scale. This led to industry consolidation. In 1995, the ten largest mortgage origi nators made 25.3 percent of all mortgages; by 2005, it was 32.7 percent.10 Thus, the net impact of securitiza tion on lender competitiveness is unclear. It is likely that the mortgage delivery system, in cluding the use of brokers on the front end and securiti zation on the back end, affects how lenders compete, including how lending market standards are set. How ever, the lack of data makes it difficult to directly tie brokerages and the rest of the mortgage delivery system to market conditions. The primary data on mortgages come from the information lenders are required to re port to the Federal Financial Institutions Examination Council under the Home Mortgage Disclosure Act (HMDA). The HMDA data identify lenders and give some information on the disposition of a mortgage, but they do not include information on how a mortgage applicant connects with a lender, including whether a broker was involved in the lending process. The sup plementary data on mortgages that I use in this article— from Lender Processing Services (LPS) Applied Analytics (formerly known as McDash Analytics)— also do not have information on the front end of the mortgage process. The best option I have is to use information on lenders as a proxy for the mortgage origination processes they use—and thus the lenders’ effect on lending market competition and conditions. I use HMDA and LPS data to examine both how mortgage characteristics differ by lender type and how the distribution of lender types within a market affects mortgage characteristics in the market. I find that, on average, banks make ex ante safer loans than IMBs do, both on an absolute scale and relative to IMBs in the counties where they lend. Also, mortgages issued by banks have lower loan-to-income ratios and lower 3 loan-to-value ratios, and banks’ borrowers have high er FICO (Fair Isaac Corporation) scores.11 Among banks, I find that local banks make safer loans than nonlocal banks do, with nonlocal banks falling be tween local banks and IMBs. I examine how the shift in lending in a market from one type of lender to another affects all the lenders in a market. This gives an indication of whether lender type affects how a firm competes. If lender type does not matter, then the shift in lending should have no impact. I find that a shift in lending toward a particu lar type of lender is associated with a larger change in lending standards at that type of lender than at other types of lenders. The interesting thing is that when a particular category of lender increases its share in a local mortgage market, that category of lender makes mortgages with higher loan risk, but to borrowers who are, on average, of higher quality. For example, when the mortgage share of local banks in a market increases, those banks issue mortgages with higher loan-to-income and loan-to-value ratios (higher loan risk), but to bor rowers with higher FICO scores (lower borrower risk). The impact of a change in the share of mortgages issued by a particular type of lender on other types of lend ers is much weaker. So, for example, a shift in the share of mortgages issued from local banks to IMBs has a generally insignificant impact on loan standards at nonlocal banks. I also examine whether large metropolitan areas are different from less densely populated areas. Sepa rating counties (markets) into those in large metro politan statistical areas (MSAs) and those in small MSAs,121 find that the impact of an increase in the share of a particular category of lender on that category’s lending standards is weaker in the large-MSA counties than in the small-MSA counties. Data The primary source of mortgage data that I use comes from information that lenders are required to report under the Home Mortgage Disclosure Act. HMDA mandates that lenders report data for the vast majority of mortgage applications.13 For each application, the HMDA data provide the name of the lender, its type, and loan information, including the location of the borrower. Lenders are required to report information on all types of residential mortgages, including loans used for purchases of single-family homes, loans used for purchases of multifamily dwellings, loans to refi nance existing mortgages, and loans for home im provement. To make the comparisons in this article as revealing as possible, I restrict the sample to loans used for purchases of single-family homes and, within 4 single-family loans, drop both second mortgages and home equity lines.14 For most of the analysis, I separate lenders by whether or not they also take deposits. In stitutions that both make loans and take deposits are regulated and chartered differently from those that only make loans. The deposit-taking institutions, which I generically refer to as banks, comprise commercial banks, thrift banks, and credit unions.151 refer to the non-deposit-taking lenders as independent mortgage banks, and this category includes specialized mortgage lenders and independent finance companies. One important drawback of the HMDA data is that a lender is classified without regard for whether the lender is the subsidiary of a different kind of institution. So, a mortgage made by a mortgage bank that is the sub sidiary of a commercial bank holding company is classi fied by HMDA in the IMB category. Instead, I classify lenders by the type of lender that their parent organi zation is. This assumes that major strategic choices are made at the parent organization level. This also assumes that where a lender books a mortgage is a matter of lender policy, meaning, for example, that some parent organizations book these loans at a bank subsidiary, while others book them at a mortgage bank subsidiary.16 In this article, I use quarterly HMDA data from 1995 through 2007. During this period, total mortgages issued increased from 1995 through the third quarter of 2005 (see figure 1). However, the rate of increase was not constant. From 1995 through 1999 (the early run-up period), home purchases increase at a rate of 8.4 percent. This falls to a rate of 3.8 percent from 2000 through 2003 (the mid run-up period), before rocket ing up at a rate of 11.9 percent from 2004 through the third quarter of 2005 (the late run-up period). From the fourth quarter of 2005 through 2007 (the housing bust), there is a sharp decline in home purchases. The pattern is superficially similar to the pattern in home prices, as indicated by the Federal Housing Finance Agency’s (FHFA) House Price Index (HPI), also re ported in figure l.17 But home prices increased faster during the 2000-03 period than during the 1995-99 period (see, for example, Haines and Rosen, 2007, for a discussion of home price changes). There is likely to be a difference in how banks connect with potential borrowers, depending on their presence in a market. Potential borrowers connect with a bank because of a pre-existing relationship, such as a checking or savings account. They may also walk into (or phone) one of the bank’s branches. These two approaches are likely to be correlated with the bank having a physical presence (that is, a branch) in the borrower’s local market. I define a mortgage as com ing from a local bank if the lending bank has a branch 1Q/2011, Economic Perspectives FIGURE 1 Total number of mortgages and home prices millions of mortgages index, 1992 = 100 3.0 Mid run-up period Early run-up period 2.5 Late run-up period 300 Housing bust 250 2.0 200 1.5 150 1.0 100 0.5 50 0 0 1995 ’97 ’99 2001 ’03 ------- Mortgages (left-hand scale) ------- FHFA HPI (right-hand scale) ’05 ’07 Note: See the text for details on the four periods.

Federal Reserve Bank of Chicago in the county where the home pur chased with the mortgage is located. Alternatively, a borrower may use a mortgage broker (or an Internet equivalent) to help choose a lender. Brokers allow a bank to make mort gages without having a physical presence to attract customers. I de fine a mortgage as coming from a nonlocal bank if the lending bank has no branches in the county where the home purchased with the mort gage is located. While I do not know whether a borrower has a pre-exist ing relationship with a bank, walks into a branch, or uses a broker, I as sume that it is more likely that a loan from a local bank is made through a branch or pre-existing relationship (that is, the retail channel). The vast majority of loans made by nonlocal banks (and IMBs) come through brokers (that is, the wholesale chan nel). In the entire sample, 28.46 percent of mortgages are made by local banks and 40.45 percent are made by nonlocal banks (of course, a bank can be a local bank in some markets and a nonlocal bank in other markets).18 Figure 2 shows the share of mortgages made by local banks, nonlocal banks, and IMBs over the sample period. The share of mort gages made by local banks declined steadily from 1995 through the third quarter of 2006, that is, during the period when housing prices rose and into the start of the housing bust. In the first quarter of 1995, local banks had a share of 34.26 percent of the mortgages made, but by mid2006, this share had decreased to 23.84 percent. In 1995-99 (the early run-up period), the drop in the num ber of mortgages made by local banks was balanced by the rise in the number of mortgages made by nonlocal banks. But as home prices began to increase at a faster pace, the share of mortgages made by IMBs began to rise. At the start of 2000, IMBs had a share of 26.68 percent 5 of the mortgages made, but this FIGURE 3 quickly increased to 37.10 percent Mortgage application denial rates, by lender type in the first quarter of 2005. Starting in late 2005, as home prices began to fall and private securitization markets shut down, these patterns reversed. By the end of 2007, the share of mortgages made by local banks increased to 37.90 percent, while the share of mortgages made by IMBs fell to 21.59 percent. Note that the decline in IMB share in 2006-07 is at least partially due to the failure of American Home Mortgage and several other IMBs. Up to now, I have been exam ining mortgages issued by lenders.

Finally, the share of loans in HMDA data that are matched to LPS data increases over the sample period, paralleling the increased servicer coverage by LPS. Differences across lender types In this section, I present information on how various loan and borrower characteristics differ across lender types. Again, I focus on three lender types: local banks, nonlocal banks, and IMBs. Banks include all depository institutions (commercial banks, thrift banks, and credit unions); when appropriate, I discuss the different depository institutions. The differences in mortgage characteristics across lender types are presented in three different ways in table 1. Panel A of table 1 presents full sample means. For each variable, I take the mean for each quarter of the sample period. The mean and standard deviation of the quarterly means are reported in panel A. I take the mean of quarterly means rather than the mean of the entire sample because the number of loans increases over time, and I do not want the means to overweight the latter part of the sample. One issue with using these means to compare lender types is that lender types are not uniformly distributed across markets. As a control for this, I take the average of each variable for each local market in each quarter, using counties as local markets. Panel B of table 1 reports the average difference be tween the local market average for a lender type and that market’s average for all lenders. This is informative about how loans differ across lender types. For example, the proportion of fixed-rate mortgages (FRMs)20 at local banks is 77.17 percent, which is 0.29 percentage points lower than the average proportion of fixed-rate mortgages at all lenders (seventh row in panel A). Does this mean that local banks give too few fixed-rate mortgages? Not necessarily. As shown in panel B (sixth row), local banks give 2.45 percentage points more fixed-rate mortgages than the average of lenders in the markets they are in. This suggests that lenders in markets with many local banks issued a smaller percentage of fixed-rate mortgages than did lenders in other markets. Finally, as figure 1 (p. 5) shows, the sample period includes a period of in creasing sales and prices followed by a period of declin ing sales and prices. Rather than chart every variable, I report the sample averages for three interesting quarters in panel C of table 1.1 show the values in the first period a variable is in the sample; the fourth quarter of 2004, to reflect the peak of sales and prices; and the fourth quarter of 2007, to observe the effects of the declining sales and prices. In general, the three different ways of looking at the data indicate the same patterns, but I discuss them in more detail when they do not. Federal Reserve Bank of Chicago I use the data in table 1 to examine how mort gage characteristics differ by lender type. In doing this, it is useful to divide mortgage characteristics roughly into three groups. The first is loan risk. These are the features that have to do with risk introduced by the size of the mortgage. The second is borrower quality. These characteristics measure the risk of the borrower more than the mortgage itself. There will be some overlap in the first two groups. Finally, I include some variables that are likely to be more weakly cor related to loan or borrower risk. The first characteristic is the ratio of the loan amount to the borrower’s income. Borrowers with a larger loan relative to income, all else being equal, are more like ly to have trouble paying their mortgages. To measure the loan-to-income ratio, I divide the amount of the loan by the borrower’s reported income from the HMDA data.21 Figure 4 (p. 10) charts this ratio for the three types of lenders over the sample period. Several things are apparent from the data. On average, IMBs lend more per dollar of income than banks do (see also table 1, panel A, second row). While not shown in the figure, mortgages issued by thrift banks have a higher average loan-to-income ratio than do mortgages issued by com mercial banks, and the mortgages made by credit unions have the lowest ratio of all lender types. The raw aver ages across the types of banks (table 1, panel A, sec ond row) indicate that local and nonlocal banks lend the same amount as a fraction of borrower income— that is, 2.31. But, mortgages issued by local banks have a loan-to-income ratio (table 1, panel B, first row) that is 0.07 (7 percentage points) lower than the average of lenders in the markets they are in, while mortgages from nonlocal banks have a ratio that is only 0.02 lower, with the difference between 0.07 and 0.02 being statis tically significant. This would arise if local banks had made a lot of mortgages in markets where the loan-toincome ratio was higher than in those markets where nonlocal banks made a lot of mortgages, so that the 2.31 loan-to-income ratio for local banks is 0.07 below the average of lenders in their markets, while the 2.31 ratio for nonlocal banks is only 0.02 below the average of lenders in their markets. The loan-to-income ratio for all lenders rose significantly over the sample period, from 2.08 in the first quarter of 1995 to 2.61 in the last quarter of 2007 (table 1, panel C, second row). The rate of increase of the loan-to-income ratio was fastest from 2000 through 2004, precisely when home prices were rising most quickly (see figure 4, p. 10). A second measure of loan risk is the loan-tovalue ratio (table 1, panel A, third row), available from the LPS data.

Val ues for selec ted quar ters Summary statistics, by lender type average loan-to-value ratio for all lenders is 83.07 percent (table 1, panel A, third row), and it decreases significantly over the sample period (table 1, panel C, third row). As with many of the other indicators, the loan-to-value ratio suggests that IMBs are making the riskiest loans and local banks are making the saf est ones. Panel B of table 1 (second row) shows that mortgages issued by local banks have a loan-to-value ratio 2.44 percentage points below the average of lenders in their mar kets, while mortgages issued by IMBs have a loan-to-value ratio 1.39 percentage points above the average of lenders in their markets. The FICO score (table 1, panel A, fourth row) is intended to provide a broad-based measure of borrower quality. It includes infor mation from the borrower’s other loans, credit history, and other rele vant factors. The FICO score is com monly used to evaluate whether to grant mortgages and other forms of consumer credit. It ranges from 300 through 850, with a higher score representing a safer borrower. I use the FICO score at loan origination as another measure of borrower quality. The LPS data report the FICO score starting in 1997. As with the loan-to-income ratio, these scores indicate that borrowers with mortgages from IMBs are riskiest, since they have the lowest average FICO scores, and borrowers with mortgages from local banks are the safest, since they have the highest average FICO scores (table 1, panel A, fourth row, and panel B, third row). In contrast to the loanto-income ratio, however, FICO scores indicate that borrowers got safer over time. The average FICO score rose from 698.5 at the start of 1997 to 715.4 at the end of 2007 (table 1, panel C, fourth row); this trend is also noted by Bhardwaj and Sengupta (2010) for subprime mortgages. The differences between 9 the trends for the loan-to-income ratio and FICO score could reflect the difference between the risk of the mortgage and the risk of the bor rower prior to getting the mortgage. The LPS data also contain an indicator of whether a loan is con sidered subprime (that is, loans graded “B” or “C,” as opposed to loans graded “A,” which are of prime quality). As noted previously, the LPS sample underrepresents subprime loans. LPS data cover about 58 percent of all loans at the end of the sample period, in 2007, but they only cover 33 percent of subprime loans. Thus, the shares of subprime lending in the data I use should be roughly doubled to get the share of subprime lending over all. However, the number of sub prime loans in the LPS data with respect to the number of subprime loans in mortgage-backed securities is relatively constant over time. Thus, while there are too few sub prime loans in the LPS sample, there is no reason to believe that percentage changes in subprime loans in the LPS data do not reflect the overall changes in subprime lending. A mortgage is often classified as subprime because of the low credit quality of the borrower (it also could reflect the size of a mortgage relative to the borrower’s ability to repay). Over the entire sample period, IMBs issued fewer subprime mortgages than banks did (table 1, panel A, sixth row, p. 8). Examining subprime lending over time, I notice some interesting patterns. As illus trated in figure 5, from 1995 through 2001 there was little subprime lending at any type of lender. Nonlocal banks started making a significant number of subprime mortgages in 2002. IMBs did not start making a sig nificant number of these loans until 2004, but when they did, subprime mortgages went from 1 percent of their business to 8 percent in just six months. IMBs seemed to use subprime loans to expand, while nonlocal banks added subprime lending at a time when their share of lending was declining (see figure 2, p. 5). Thus, subprime lending may have played a different role at the two types of lenders. When the housing market started to have troubles in 2005, IMBs were the fastest to withdraw from the subprime mortgage market. This is consistent with IMBs being more flex ible than other types of lenders. io The measures of loan risk and borrower quality generally indicate that borrowers with mortgages from IMBs are riskier than those with mortgages from banks; in addition, borrowers with mortgages from local banks generally seem safer than those with mortgages from nonlocal banks. There is evidence that the riskiness of borrowers rose during the sample period, with the largest increases during 2000-04, when home prices were also increasing at their fastest rate (see, for ex ample, figures 4 and 5). I next turn to examining other mortgage features. Mortgages come in many types, but I separate them in two ways. First, I split fixed-rate mortgages from adjust able-rate mortgages (ARMs).23 On average, over threequarters of all mortgages had fixed rates, but this share moved around as mortgage rates and market conditions changed over the sample period. More borrowers chose fixed-rate mortgages when the yield curve was shallow or inverted relative to when it was steep.24 The propor tion of fixed-rate mortgages rose from 61.50 percent in the first quarter of 1995 to 95.28 percent in the third quarter of 1998; it edged down to 95.06 percent in the first quarter of 2001, before falling to 56.52 percent in the second quarter of 2005. At that point, mortgage 1Q/2011, Economic Perspectives in its portfolio. It could sell the mort gage to a GSE or have the mortgage Share of subprime mortgages, by lender type guaranteed by a government agency (such as Ginnie Mae27) prior to sell ing the mortgage into securitization. Or it could sell the loan to a private financial intermediary, often as a prelude to securitization. Since the selling process can take time, I use the status of the mortgage 24 months after origination as my measure of whether it is held in portfolio, secu ritized with a GSE or government guarantee, or sold to a private firm.28 My measure may introduce a bias because a mortgage is more likely to end up at one of the large servicers in the LPS data if it is securitized. -------- Local bank The evidence on loan sales and se ------- Nonlocal bank curitization is likely to be indicative ------- Independent mortgage bank of differences across the types of lenders, but not of the true levels Note: See the text for details on the four periods.

I also examine the share of so-called jumbo loans. The loan characteristic variables are consistent Fannie Mae and Freddie Mac were government-spon with local banks making safer loans than other types sored enterprises (GSEs) that purchased loans from of lenders. This may be because they have a different lenders prior to securitizing them.25 Fannie and Freddie business model for mortgages, as evidenced by the fact could only buy loans equal to or less than a given size, that they keep a larger share of these loans in their port known as the conforming loan limit; this limit ranged folios.

But the simple statistics do As indicated in the prior paragraph, lenders were not allow us to determine whether the presence of able to sell certain mortgages to Fannie Mae and one type of lender affects the mortgages offered by Freddie Mac. In general, a lender had three options other types of lenders. Here, I use a regression model when it issued a mortgage. It could hold the mortgage to tease this out. FIGURE 5 Federal Reserve Bank of Chicago 11 The baseline model allows lending standards to be a function of lender types and market conditions: 1) Lending standards.ct =/{Lendershares.ct Lending market conditionsct Economic conditionsc,t, l7’ where z is the type of lender (local bank, nonlocal bank, or IMB), c refers to the local market (county), and t is the time period. The right-hand side variables are all lagged one quarter to mitigate potential endo geneity problems.29 The characteristics I examine are those that focus on lending standards. The loan-to-income ratio and the loan-to-value ratio are direct measures of loan risk, while the FICO score and the share of subprime loans are measures of borrower quality (of course, a high-quality borrower with a high FICO score can nonetheless take a risky loan—for example, one with a very high loan-to-income ratio). Classifying the loan denial rate along these lines is more difficult. Loans can be denied either because a borrower has a weak profile or because the loan is too risky given the qual ity of the borrower. Thus, it mixes loan risk and borrower risk. Each of these characteristics can be affected by competitive conditions in a market, which include the different incentives of each type of lender. I use each lending standard as both a dependent variable and a control because each can pick up aspects of market conditions other than differences across lenders. A high average loan-to-income ratio can re flect borrowers needing to commit a larger share of income in order to purchase a home in markets where homes are relatively expensive. Similarly, expensive homes may reduce the percentage down payment that borrowers can make, leading to a higher loan-to-value ratio. Additionally, in the recent crisis, some borrowers with loan-to-value ratios above 100 percent have walked away from their mortgages because they have negative equity in their homes. The risk of this happening is obviously higher when a mortgage has a larger initial loan-to-value ratio. More lender competition can reduce average FICO scores or lead to fewer loans being de nied.30 Similar to the loan-to-income ratio, the share of subprime loans in a market may be correlated with home prices in the market. Of course, it can also be affected by competition among lenders and changes in securitization markets. Some aspects of loan quality that have a weaker correlation with loan risk are included as controls but not as dependent variables. The share of loans kept in portfolio is likely to be related to the types of lenders in a market. There may be a weak correlation with 12 risk because it is more difficult to securitize unusual loans. The proportion of fixed-rate mortgages may reflect borrower strength, especially in later years when borrowers often qualified for mortgages based on their ability to meet the initial loan payments. The ability of borrowers of a given income and risk to qualify for larger adjustable-rate mortgages than fixed-rate mortgages means that, all else being equal, fixed-rate mortgages were safer to fund. A number of the lending market standard variables are affected by the ability of potential borrowers to purchase a home. I control for prices in two ways. First, I include the percentage change in home prices over the past quarter in the local market (so the change in period t - 1 is the percentage difference from period t - 2 to period t - 1). I measure prices using the FHFA HPI. There is an extensive debate in the housing liter ature about what the best price index is (see Rosen, 2008; and Case and Shiller, 2003). I choose the FHFA HPI because it is available for a wider number of mar kets than other constant-quality indexes, such as the Standard and Poor’s/Case-Shiller Home Price Index. The second control I use is the price-to-rent ratio in the local market. I measure rents using the owners’ equivalent rent component of the Consumer Price Index (CPI-OER), which is put out by the U.S. Bureau of Labor Statistics. The price-to-rent ratio is, thus, the ratio of the FHFA HPI to the CPI-OER. A high value indicates that owning a home is expensive relative to renting. For both controls, I use the data for the MSA that a market is in if available. Otherwise, statewide data are used. I also add additional controls for local economic conditions. These include measures of the unemploy ment rate and income per capita.31 For both variables, I use the mean value for the MSA a county is in if that is available. Otherwise, I use the mean value for the state. To pick up any systematic local differences not captured by the other controls, I include countylevel dummies in the main regression. There were secular trends in many of the lending market standards; for example, the rise of securitiza tion and the increased use of the “originate-to-distribute” model for mortgages during the run-up in home purchases (see figure 1, p. 5) affected the mortgages lenders issued (see, for instance, Keys et al., 2010). Such trends may have given lenders an incentive to issue high loan-to-income, high loan-to-value, or low FICO-score mortgages. To control for the com mon effects of the rise and fall of securitization, I include time dummies in the regressions. The time dummies also pick up other changes in lending tech nology, economic conditions, and interest rates that 1Q/2011, Economic Perspectives Finally, since one objective is to examine how the distribution of lender Effect of mortgage and market characteristics types affects loan characteristics, I ex on loan-to-income ratio in local markets, clude some small markets.

The coefficient on the nonlocal bank share is negative (sec are common across markets. Including time dummies ond row of table 2). This means that shifting loan share helps me focus on how the loan shares of different from IMBs to nonlocal banks reduces the average lender types affect lending market standards. TABLE 2 Federal Reserve Bank of Chicago 13 loan-to-income ratio at local banks in the market. Also, the coefficients on the local bank share and the nonlocal bank share (first and second rows of table 2) are signif icantly different from one another (as shown in the fi nal row of the table, which gives the p value for a test that the two coefficients are equal). So, a movement in lending from nonlocal banks to local banks is asso ciated with significant increases in the loan-to-income ratio at local banks. The results for the loan-to-income ratio at nonlocal banks and IMBs are presented in the second and third columns of table 2. One common element in all three regressions is that when the loan market share of a particular type of lender is increasing, the average loanto-income ratio of mortgages from that type of lender increases. This is indicated by the positive coefficients on local bank share in the local bank regression (first row, first column) and on nonlocal bank share in the nonlocal bank regression (second row, second column). It is also indicated by the negative coefficients on both bank shares in the IMB regression (first and second rows, third column); both local and nonlocal bank shares decreasing means that the IMB share is increasing. When one type of lender increases its market share in period t - 1, mortgages from that type of lender are riskier, all else being equal, in period t. As described previously, the loan-to-income ratio for mortgages issued by local banks changes when there is a shift in market share between nonlocal banks and IMBs (second row, first column). This ratio, however, does not change for mortgages issued by nonlocal banks when there is a shift in market share between local banks and IMBs (first row, second column). Similarly, mortgages issued by IMBs do not change their loanto-income ratio when market share shifts between lo cal and nonlocal banks (final row, third column). I now briefly discuss the coefficients on the other control variables in table 2. These are representative of the coefficients on later regressions. There is gen erally only a weak correlation among the measures of borrower quality. For example, in table 2, the coef ficients on FICO score (fourth row) and the subprime share (sixth row) are each significant in only one re gression, while the coefficients on the loan-to-value ratio (third row) and the loan denial rate (fifth row) are not significant for any of the regressions. Changes in some of the macroeconomic factors featured in table 2 can affect the loan-to-income ratio at the different lender types. Higher income (tenth row) is associated with an increase in the loan-to-income ratio in the mortgages made by nonlocal banks, but a reduction in the loan-to-income ratio in the mortgages made by local banks and IMBs. This may indicate that 14 changes in local income are associated with shifts among lender types. When the price-to-rent ratio (twelfth row) increases, buying a home is relatively more expensive than renting one. This makes it likely that when people do buy a home, they are not able to afford a large down payment, and thus they have a large loan-to-income ratio. Table 3 presents the coefficients on the lender share variables for regressions of equation 1, using the averages of the loan characteristics by lender type as the dependent variables. This repeats the regressions in table 2 and also includes regressions where the de pendent variables are the loan-to-value ratio, FICO score, loan denial rate, and subprime mortgage share. The other controls, although not shown, are the same as those for the regressions in table 2. Two patterns are apparent from table 3. First, changes in lender shares have a different impact on loan risk characteristics than on borrower quality characteristics (here, the loan denial rate looks more similar to a loan risk characteristic than a borrower quality characteristic). While changes in lender shares are associated with riskier mortgages as measured by the loan risk indicators, such changes are associated with less risky mortgages as measured by borrower quality indicators. For example, an increase in the local bank share is associated with smaller loan-to-income and loan-to-value ratios and a larger loan denial rate at IMBs (third column), all indicating less risky mort gages. However, this increase is also associated with lower FICO scores and more subprime lending, which indicate lower-quality borrowers. One possible expla nation is that high-quality borrowers were taking out risky loans; that is, borrowers with higher FICO scores took out loans that were risky enough to be classified subprime. Consistent with this interpretation, others have documented that FICO scores of subprime loans have increased since 2000 (Demyanyk and Van Hemert, 2009; and Bhardwaj and Sengupta, 2010). However, an analysis of why direct measures of loan risk seem to move in the opposite direction as measures of borrower quality is beyond the scope of this article. A second pattern in table 3 is that, as a particular type of lender increases market share, the loans made by that type of lender tend to get riskier. As noted pre viously, the loan-to-income ratio for mortgages made by a lender type is larger as the own-type lender share increases.33 The loan-to-value ratio increases and the share of loans denied decreases in these circumstances. The picture for subprime shares is mixed, with local banks (first column) having a larger share of subprime lending when local bank share increases, but nonlocal banks and IMBs (second and third columns) having the opposite reaction to own-type lender share increases 1Q/2011, Economic Perspectives TABLE 3 Effect of mortgage and market characteristics on loan risk and borrower quality in local markets, by lender type Independent Dependent variable Loan-to-income ratio Independent variable Local Nonlocal Test: Local = Nonlocal Loan-to-value ratio Local Nonlocal Local Nonlocal Test: Local = Nonlocal Loan denial rate Local Nonlocal Test: Local = Nonlocal Subprime share Nonlocal banks mortgage banks 0.223* -0.259" 0.073 0.175" -0.250*** -0.320*** 0.000 Test: Local = Nonlocal FICO score Local banks Local Nonlocal Test: Local = Nonlocal 0.021 0.007 0.066*** 0.389 0.000 0.000 -0.075*** -0.052*** 0.035 104.930" 10.050 11.686 15.958 -144.131*** -81.212*** 0.013 0.726 -0.076*** -0.016 -0.071*** -0.176*** 0.000 0.000 0.026" -0.017* 0.000 -0.016" 0.000 0.018 0.078* -0.077" 0.023 0.255*** 0.308*** 0.021 0.026*** 0.023*** 0.522 *p <0.10 **p < 0.05 ***p < 0.01 Notes: FICO score indicates the Fair Isaac Corporation credit score.

(see note 33). Consistent with the differences between own-type share changes and other-type share changes, there is generally a statistically significant difference between the coefficients on the local bank share and the nonlocal bank share (p values for these tests are reported in the table). Lending standards at local banks seem to shift more after there are changes in nonlocal bank share, com pared with the lending standards at nonlocal banks fol lowing changes in local bank share. To see this, compare the coefficients on nonlocal bank share in the first column with the coefficients on local bank share in second column of table 3. This shows that a shift in mortgage shares from IMBs to nonlocal banks is associated with a decrease in the risk of mortgages issued by local banks, while a shift from IMBs to local banks has little impact on the risk of mortgages issued by nonlocal banks. For instance, when the nonlocal bank share increases, the loan-to-income and loan-to-value ratios for mortgages issued by local banks decrease, Federal Reserve Bank of Chicago indicating safer loans (table 3, second and fifth rows, first column). However, an increase in the local bank share has no significant impact on these ratios for mortgages made by nonlocal banks (table 3, first and fourth rows, second column). It is instructive to compare the results in table 3 with those in panel A of table 1 (p. 8). As shown in panel A of table 1, mortgages issued by local banks have the lowest loan-to-income and loan-to-value ratios. Yet, as the coefficients on local bank share in the first column of table 3 show, when local bank lender share increases in a market, loans issued by local banks tend to have higher risk (that is, higher loan-to-income ratios, higher loan-to-value ratios, a greater likelihood to be subprime, and lower loan denial rates). In addition, as market share shifts from IMBs to nonlocal banks, mortgages issued by nonlocal banks generally increase in risk, as indicated by the coefficients on nonlocal bank share in the second column of table 3. Specifically, the loan-to-income 15 and loan-to-value ratios increase and the loan denial rate decreases, consistent with riskier lending practices (although the share of subprime loans decreases, pointing in the other direction). One interpretation consistent with this is that lenders compete more with lenders of the same type than lenders of other types, and competition manifests itself in allowing borrowers to take larger loans relative to both borrower income and home values. Of course, this does not necessarily mean that lenders are providing mortgages to riskier borrowers. Borrowers with mortgages from local banks have the highest FICO scores, but competition among local banks does not seem to lower the average FICO score of borrowers who get their mortgages from local banks. Since the proportion of local bank lending fell during most of the sample pe riod, until the housing crisis started in late 2005 (recall figure 2, p. 5), we can think about how this might have changed lend ing standards. As local banks made fewer loans in a market, loan risk decreased at local banks and increased at IMBs. To the extent that lender share by local banks was lost to nonlocal banks and IMBs, the net effect on loan risk at nonlocal banks was small. It is important to remember that there are time dummies in these re gressions, so any changes are above and beyond secular trends across lender types.

Lending standards and market size The markets in the sample range from small counties with populations of less than 50,000 all the way up to the New York City area with over 10 mil lion residents. To see whether lenders compete the same way in the large metropolitan areas as elsewhere, I divide the sample of counties (markets) into two categories. I place counties in MSAs. For very large MSAs, I further divide them into metropolitan divisions. Metropolitan divisions are groups of closely tied con tiguous counties that serve as distinct employment districts. They are part of MSAs with populations of at least 2.5 million. I define a county as a large-MSA county if it is in one of the top 50 metropolitan divi sions/MSAs; otherwise, I define a county as a smallMSA county. The MSAs are ranked by population according to the 2000 U.S. Census. The largest metro 16 area is the New York-Wayne-White Plains, NY-NJ metropolitan division and the fiftieth largest is the Memphis, TN-MS-AR MSA. Table 4 presents a com parison of large-MSA and small-MSA counties. There are some significant differences between mortgage market conditions across large-MSA and small-MSA counties. However, it is not clear that one type of county has riskier conditions than the other type. To see whether the differences between markets in large and small MSAs affect competition among lenders, I split the lender share variables by whether a market is a large-MSA or small-MSA county. Table 5 presents results for regressions including these variables. The regressions include the same nonlender control variables as the regressions in tables 2 and 3, but only the coefficients on the lender share variables are reported. 1Q/2011, Economic Perspectives Federa l Res erv e Bank of Chicag o TABLE 5 Effect of mortgage and market characteristics on loan risk and borrower quality in local markets, by lender type and metropolitan statistical area (MSA) size Local banks Dependent variable Loan-to-income ratio Independent variable Local Nonlocal Test: Local = Nonlocal Loan-to-value ratio Local Nonlocal Test: Local = Nonlocal FICO score Local Nonlocal Test: Local = Nonlocal Loan denial rate Local Nonlocal Test: Local = Nonlocal Subprime share Test: Local = Nonlocal Small Test; L = S 0.056 -0.572*** 0.315** -0.097 0.151 0.011 0.000 0.000 0.009 -0.182*** 0.115** -0.023 0.003 0.000 168.303*** -37.756 86.511* 34.080 0.202 0.240 0.419 -0.084*** -0.029** 0.000 0.241 0.088 0.045*** -0.003 0.000 0.003 0.048 0.003 -0.060*** 0.009 0.000 Local Nonlocal -0.018 -0.044** 0.018 Independent mortgage banks Nonlocal banks Large 0.109 0.016 Large Small Test: L = S Large Small Test; L = S -0.285*** -0.296*** -0.239** -0.331*** 0.756 0.780 0.880 0.364 -0.042** -0.063*** -0.086*** -0.045*** 0.005 0.084 0.527 -185.701*** -82.374** 0.002 0.954 0.001 -0.112 0.085 0.126 0.321** 0.000 0.449 0.020 0.012 -0.022 0.013 0.110*** 0.000 0.955 0.000 0.023 0.142 0.871 0.080 16.403 -7.369 12.522 28.427 0.269 0.268 -0.097*** -0.110*** 0.453 0.026 0.707 -0.067** -0.209*** 0.000 0.004 0.008 -0.003 -0.027*** 0.664 0.010 0.786 0.003 -32.116 -84.943** 0.148 0.003 0.133*** 0.284*** 0.000 0.304*** 0.324*** 0.005 0.023*** 0.034*** 0.023*** 0.087 0.040 0.000 0.362 0.477 0.022 0.985 *p < 0.10 **p < 0.05 ***p< 0.01 Notes: FICO score indicates the Fair Isaac Corporation credit score.

The pattern of responses to mortgage share changes in both groups of markets is similar to that of the full sample—with one exception. In large-MSA markets, lenders, especially local and nonlocal banks, seem to react less to changes in market share of lenders of the same type. For example, a change in local bank share is not associated with a significant change in the loanto-income ratio or the loan-to-value ratio of mortgages issued by local banks (the coefficients 0.056 and 0.009, as given in the first column of table 5, are not significantly different from zero); also, a change in local bank share is not associated with a significant change in the share of subprime lending at the local banks (the coefficient -0.018 in the first column of table 5 is not significantly different from zero). All these coefficients are statisti cally significant in the similar regression for the sample as a whole (table 3, p. 15). This suggests that compe tition may be more complex in counties that are part of large MSAs. Table 5 also presents tests of differences in the re gression coefficients across large-MSA and small-MSA markets. The p values reported in the columns labeled “Test: L = S” are for tests of the differences between the coefficients in the large-MSA regressions and those in the small-MSA regressions. These results show little dif ference in how banks react to changes in local bank mar ket share based on MSA size. However, in large-MSA markets relative to small-MSA markets, changes in nonlocal bank lender share are generally associated with larger changes in local bank mortgage characteristics but smaller changes in nonlocal bank mortgage character istics. Again, this is consistent with differences in how lenders compete across MSAs that differ in size. The results presented in tables 3 and 5 show that the distribution of lender types affects lending standards and loan characteristics. During the housing boom, the share of lending by local banks decreased, since both nonlocal banks and IMBs increased their market share. All else being equal, this means that loan risk and borrower quality fell for mortgages made by local banks, even more so in small-MSA markets than in large-MSA markets. To the extent that lending migrated to nonlocal banks from IMBs, loan risk and borrower quality increased for mortgages made by nonlocal banks, again more so in small-MSA markets than in largeMSA markets. As the share of loans made by IMBs increased, loan risk and borrower quality increased at IMBs, in both large-MSA and small-MSA markets. 18 Conclusion I examine mortgage lending during the period 1995-2007. This was a period of extensive change in the mortgage market. There was a boom and bust in home purchases and home prices. What caused the boom and bust is a big question that is still being de bated. One possible contributing factor is the shift in the mortgage delivery process. During the housing boom, fewer and fewer borrowers got their mortgages from local banks; both nonlocal banks and IMBs gained mar ket share. This could have affected mortgage markets because each type of lender approaches mortgage lending differently. Local banks have a more intensive retail focus and are most likely to keep loans in port folio. Banks that make loans outside their local mar kets (nonlocal banks) are likely to use the wholesale lending channel for these loans, but being banks, they sometimes will keep loans in portfolio. In contrast, IMBs are wholesale lenders that sell essentially all the loans they originate. The changes in market shares of lender types could be important because the characteristics of mortgages are a function of the lender type. Local banks tend to make loans that appear ex ante safer—for example, they have lower loan-to-income and loan-to-value ratios. Thus, the market shift away from mortgages issued by local banks could lead to riskier mortgages being made. The shift in lenders can also have an indirect effect. In part, loan characteristics for mortgages made by a particular type of lender may depend not only on that type of lender’s cost-benefit trade-off, but also on the competitors it faces. I show that an increase in the mortgage market share of a particular type of lender is associated with other lenders of the same type increasing the average loan risk of their mortgages; at the same time, this increase in the mortgage market share of a particular type of lender is associated with an increase in the average quality of their borrowers. This impact is larger in counties that are in small MSAs. My analysis suggests that the efforts to get (private) mortgage securitization markets going again might affect the types of mortgages that are issued because of their effects on lender composition. The securitiza tion market facilitates the wholesale lending channel, and is likely to increase the share of loans made by nonlocal banks and IMBs. These loans tend to be riskier on average than loans made by local banks. In addition, the indirect effect of changing the market structure may be to increase loan risk even further at nonlocal banks and IMBs, although not at local banks. Hence, both the direct and indirect effects may add to aggre gate loan risk. 1Q/2011, Economic Perspectives NOTES ’For example, see Steverman and Bogoslaw (2008). 2Subprime lending is the issuing of loans to borrowers with poor or no credit histories; mortgage securitization is the packaging and sale of bonds that have mortgages as the underlying collateral. In addition, see U.S. Congress, Joint Economic Committee (2007)— a report on the housing crisis that centers around subprime lending. 3Inside Mortgage Finance Publications (2008). 4Previous work has examined how the structure of the mortgage industry has affected discrimination in lending (see Apgar, Bendimerad, and Essene, 2007). 5This is similar to the approach in the literature examining how the size and organizational structure of competitors in banking markets can affect deposit rates and small market lending (Rosen, 2007a; Berger, Rosen, and Udell, 2007; and Park and Pennacchi, 2009). 6The values cited here are from my calculations based on data from the Home Mortgage Disclosure Act; Robert Avery, Board of Governors of the Federal Reserve System; and Federal Deposit Insurance Corporation, Summary of Deposits. 7One would expect that brokers would lead borrowers to the lender offering the best deal. However, there are allegations that some brokers steered borrowers toward loans that maximized the brokers’ com missions rather than minimized the borrowers’ costs (see, for example, the comments of Senator Christopher J. Dodd, D-CT, in 2007 at http://dodd.senate.gov/index.php?q=node/4167). 8See Wholesale Access Mortgage Research and Consulting Inc. (2005). 9There is an intermediate case, where a small lender originates a loan and then quickly sells it to a large wholesale lender under prearranged terms. See Apgar, Bendimerad, and Essene (2007) for a more detailed discussion of the different origination channels. 10This is derived from the Home Mortgage Disclosure Act (HMDA) data described later in the article. 11 An important feature of the FICO score is that it is intended to measure a borrower’s creditworthiness prior to taking out a mort gage. FICO scores range between 300 and 850. Typically, a FICO score above 800 is considered very good, while a score below 620 is considered poor. As reported on the Fair Isaac Corporation web site (www.myfico.com), in June 2009 borrowers with FICO scores above 760 were able to take out 30-year fixed-rate mortgages, or FRMs (see note 20), at interest rates that were 160 basis points lower, on average, than those available for borrowers with scores in the 620-639 range. 12Later in the article, I explain exactly how I divide the sample into large-MSA counties and small-MSA counties. this means that the history of lender activity may be more important for refinancings than for purchase loans. Also excluded are home equity lines, which are revolving lines of credit with a home serv ing as collateral. Since these loans are not generally completely drawn at initiation, their pricing and characteristics may vary from those of basic mortgages. 15The different types of depository institutions reflect differences in their charters and regulators, as well as historical differences in the types of loans they issue. A commercial bank’s primary federal reg ulator is the Office of the Comptroller of the Currency, the Federal Reserve, or the Federal Deposit Insurance Corporation. Thrift banks are regulated by the Office of Thrift Supervision; and credit unions are regulated by the National Credit Union Administration. 16The classification is based on a data set provided by Robert Avery, Board of Governors of the Federal Reserve System. 17The HPI is an index based on repeat sales information. It comes from the FHFA, which was established in 2008 by the Federal Housing Finance Regulatory Reform Act of 2008, a part of the Housing and Economic Recovery Act of 2008. The FHFA was formed by a merger of the Office of Federal Housing Enterprise Oversight (OFHEO), the Federal Housing Finance Board, and the U.S. Department of Housing and Urban Development’s government-sponsored enter prise mission team (see www.fhfa.gov for additional details). The HPI was formerly published by OFHEO. 18I have no information on branch locations for credit unions, so I assume all mortgages made by credit unions are in markets where they have branches (that is, I assume all mortgages issued by credit unions are local bank mortgages). 19A small number of loan applications that are approved but not taken are dropped from this calculation. 20A fixed-rate mortgage is one whose interest rate is fixed from its origin for its entire term. 21The LPS data include the ratio of the initial mortgage payment to the borrower’s monthly income from 2005 on. The cross-sectional pattern of the data is similar to that for the loan-to-income ratio in the HMDA data. 22I drop all observations where the loan-to-value ratio is above 250 percent, as these likely represent data errors. 23Unlike an FRM, whose interest rate is fixed from its origin for its entire term, an ARM’s interest rate can adjust periodically based on terms set in the mortgage contract. When an ARM resets after an initial defined period (which may be as short as one year or as long as seven), the interest rate and, consequently, the monthly mortgage payment may change substantially. 13For details, see Federal Financial Institutions Examination Council (2008). In general, very small lenders are exempt from filing, as are lenders that do not make loans in metropolitan statistical areas. 24A yield curve shows the relationship between yields and maturity dates for a set of similar bonds, usually Treasuries, at a given point in time. A steep yield curve means that ARMs tend to have much lower initial interest rates than do FRMs; the interest differential is small when the yield curve is relatively flat. 14The major excluded group is loans to refinance existing mortgages. The share of loans that are for refinancing varies over time, influ enced in large part by the pattern of mortgage interest rates. I exclude these loans for two main reasons. First, the exclusion makes it easier to determine the role played by the lender, since I do not have to control for changes in the mix of loans. Second, borrowers’ current lenders may have an advantage in capturing refinancing loans, and 25The full official name for Fannie Mae is the Federal National Mortgage Association. The full official name for Freddie Mac is the Federal Home Loan Mortgage Corporation. The two government-sponsored enterprises were put into conservatorship in 2008. Federal Reserve Bank of Chicago 19 26This is the limit for a single-family home, which was set by the OFHEO and is now set by the FHFA. There were higher limits for multifamily homes. 27The full official name of Ginnie Mae is the Government National Mortgage Association. 28For mortgages that leave the data prior to 24 months (which often reflects repayment or default), I use the status in the last month the mortgage is in the data to measure its disposition. 29Including additional lags does not qualitatively change the results. 31Income per capita is only available at an annual frequency. I linearly interpolate across quarters. The data come from the U.S. Department of Commerce and are based on population esti mates by the U.S. Census Bureau. The unemployment data are from the U.S. Bureau of Labor Statistics. 32Our restrictions on the number of loans eliminate 115 smaller counties from the sample. 33To find what happens when the own-type lender share for IMBs increases, one would have to take the negative of the reaction to an increase in the lender shares of local and nonlocal banks. 30FICO scores are only available from 1997 onward. For earlier years, the FICO score variable is set to zero when it is used as a control. In these years, the average FICO score for the nation is captured by time dummies. 20 1Q/2011, Economic Perspectives REFERENCES Apgar, William, Amal Bendimerad, and Ren S.

Federal Reserve Bank of Chicago 21 Monitoring financial stability: A financial conditions index approach Scott Brave and R. Andrew Butters Introduction and summary One of the key observations to come out of the recent crisis is that financial innovation has made it difficult to capture broad financial conditions in a small number of variables covering just a few traditional financial markets. The network of financial firms outside the traditional commercial banking system—that is, the so-called shad ow banking system—was at the forefront of many of the major events of the crisis, as were newer financial markets for derivatives and asset-backed securities. In the wake of the crisis, policymakers, regulators, financial market participants, and researchers have all affirmed the importance of the interconnections between traditional and newly developed financial markets, as well as their linkages to the nonfinancial sectors of the economy. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 sets forth a financial stability mandate built on this widespread affirmation. Monitoring financial stability, thus, now explicitly requires an understanding of both how traditional and evolving financial markets relate to each other and how they relate to economic conditions. Indexes of financial conditions are an attempt to quantify these relationships. Here, we describe two new indexes that expand on the work of Illing and Liu (2006), Nelson and Perli (2007), Hakkio and Keeton (2009), and Hatzius et al. (2010). In what follows, we first describe our method of index construction. The novel contribution of our method is that it takes into account both the cross correlations of a large number of financial variables and the historical evolution of the index to derive a set of weights for each element of the index. We also develop an alternative index that separates the influ ence of economic conditions from financial conditions. We then highlight the contribution of different sectors of the financial system to our indexes, as well as the systemically important indicators among them. 22 Next, we show that the indexes of financial con ditions we produce are useful tools in gauging finan cial stability. Major events in U.S. financial history are well captured by the history of our indexes, as is the interdependence of financial and economic condi tions. To further demonstrate the latter, we establish that it is possible to use our indexes to improve upon forecasts of measures of economic activity over short and medium forecast horizons. Measuring financial conditions Indexes of financial conditions are typically con structed as weighted averages of a number of indicators of the financial system’s health. Commonly, a statisti cal method called principal component analysis, or PCA, is used to estimate the weight given each indi cator (see box 1 for details). The benefit of PCA is its ability to determine the individual importance of a large number of indicators so that the weight each receives is consistent with its historical importance to fluctuations in the broader financial system. Indexes of this sort have the advantage of captur ing the interconnectedness of financial markets—a de sirable feature allowing for an interpretation of the systemic importance of each indicator. The more correlated an indicator is with its peers, the higher the weight it receives. This allows for the possibility that a small deterioration in a heavily weighted indicator may mean more for financial stability than a large deterioration in an indicator of little weight.

Here, we explain the mathematics behind PC A.1 In our explanation, x denotes the 1 x N element row vector of data at time I. The first step is to form the stacked matrix of data vectors X , where each column of this vector contains T observations of a financial indicator normalized to have a mean of zero and a standard deviation of one. The eigenvector-eigenvalue decomposition of the variance-covariance matrix XTXT then produces a set of weights referenced by the A x 1 vector W corresponding to the eigenvector associated with the largest eigenvalue of this matrix.2 These weights are used to construct a weighted sum of the x at each point in time such that the resulting index is given by / = A' W. In a general setting, variation in the frequency or availability of data makes PCA infeasible. To circum vent this issue, many indexes restrict the set of financial indicators and the time period examined at the cost of losing coverage of more recently developed financial markets and longer historical comparisons. Alternatively, Stock and Watson (2002) show how this issue can be addressed by an iterative estimation strategy that relies on the incomplete data methods of the expectationmaximization (EM) algorithm of Watson and Engle (1983). As the number of indicators becomes large, this strategy produces an index estimate with the same desirable statistical properties as PCA. The EM algorithm uses the information from the complete, or “balanced,” panel of indicators to make the best possible prediction of the incomplete, or “unbalanced,” panel of indicators. Stock and Watson’s (2002) EM algorithm begins with estimation by PCA The PCA method also has its limitations, however. For instance, often the choice of which financial indi cators to include is restricted by the frequency of data availability, as well as the length of time for which data are available. Work by Stock and Watson (2002) and others have shown how to relax some of these constraints, and we pursue this direction further so as to construct a richer and longer time series for our indexes. Our goal is to be able to construct high-frequency indexes with broad coverage of measures of risk, liquid ity, and leverage. By risk, we mean both the premium placed on risky assets embedded in their returns and the volatility of asset prices. In terms of liquidity, our measures capture the willingness to both borrow and lend at prevailing prices. Measures of leverage, in turn, provide a reference point for financial debt rela tive to equity. Federal Reserve Bank of Chicago on a balanced subset of the data to obtain an initial estimate of the index. Data for each of the financial indicators are then regressed on this estimate of the index, and the results of each regression are used to predict missing data. The index is then reestimated by PCA on both the actual and predicted data. This process continues until the difference in the sum of the squared prediction errors between iterations reaches a desired level of convergence. Stock and Watson’s (2002) EM algorithm is, however, a purely static estimation method and does not incorporate information along the time dimension into the construction of the index. In addition, it, too, is restricted by the need for an initial balanced panel of the highest-frequency indicators, given its reliance on PCA. Because most high-frequency financial indi cators are not readily available prior to the mid-1980s, this constraint is not trivial. We, instead, use this method as a starting point, but then rely on the alter native estimation procedure ofDoz, Giannone, and Reichlin (2006). Their method allows us to also in corporate information along the time dimension into our index, and is a form of what is referred to as dynamic factor analysis. ’For further details on PCA, see Theil (1971), pp. 46 48. Underlying the normalization of the data is the concept of “stationarity,” or the notion that the mean and variance of each indicator do not vary over time. For this to be true, some indicators must first be altered with a stationarity-inducing transformation prior to estimation. The stationarity-inducing transformations we used can be found in table A1 in the appendix. To allow for historical comparisons and financial innovation, our method must also be able to incorporate time series of varying lengths and different frequencies. To do so, we apply the methods ofDoz, Giannone, and Reichlin (2006) and Amoba, Diebold, and Scotti (2009) (see box 2 for details). This framework allows us to make use of weekly, monthly, and quarterly financial indicators with histories that potentially begin and end at different times. To briefly describe our method, we add a second dimension to the averaging process—namely, the timeseries dimension of the index. At each point in time, all of the available indicators are used to construct the index, ignoring those that are unavailable. The histor ical time-series dynamics of the index are then used to smooth its history; and when these indicators again 23 BOX 2 Estimating our financial conditions indexes Our FCI is constructed in a similar fashion to many coincident indicator models where the variation in a panel of time series is governed linearly by an un known common source and an idiosyncratic error term. The static measurement equation these models all have in common is of the following form: where F represents a 1 x T latent factor capturing a time-varying common source of variation in the N>'T matrix of standardized and stationary financial indica tors and T represents its N x 1 loadings onto this factor. A defining characteristic of X for our FCI is its large size in both the cross section (N) and time domain (7). Adding dynamics of some finite order to the latent factor moves the model into the large approxi mate dynamic factor framework of Doz, Giannone, and Reichlin (2006). The state-space representation of this model is given by: At = TFt + e, t’ where T are factor loadings estimated off the cross section of financial indicators and A is the transition matrix describing the evolution of the latent factor become available, the history is updated to reflect the information gained. Using this method, we construct our weekly finan cial conditions index (FCI) that takes into account both the cross-correlations of the indicators and the historical evolution of the index itself in determining the appro priate weights. The latter serves to smooth changes to the index over time, leaving behind more persistent con tributions from the indicators. This feature is desirable, particularly in real time, because it avoids putting too much emphasis on potentially temporary factors influ encing financial conditions. Following Hatzius et al. (2010), we also consider adjusting the indicators for current and past economic activity and inflation prior to construction of the index. Our “adjusted” FCI, described in box 2, is motivated by the observation that financial and economic condi tions are highly correlated. Removing the variation explained by the latter addresses potential asymmetries in the response of one to the other. For instance, a 24 over time. The latent factor’s dynamics,/?, as ex pressed in the transition matrix A are assumed to be of finite order: p = 15 weeks. Fifteen lags correspond roughly with one quarter’s worth of data. With the model in state-space form and initial estimates of the system matrices, the EM algorithm outlined by Shumway and Staffer (1982) can be used to estimate the latent factor F. At each iteration of the algorithm, one pass of the data through the Kalman filter and smoother is made, followed by reestima tion of the system matrices by linear regression.1 The log-likelihood function that results is nondecreasing, and convergence is governed by its stability. We use the PCA-based EM algorithm of Stock and Watson (2002) to provide consistent initial estimates £ £ of r and and we use linear regression on the N subsequent estimate of Fto obtain consistent initial ft is worth emphasizing, T however, that these initializations are more restrictive than necessary and serve in this framework only to considerably reduce the required number of iterations of the EM algorithm. For instance, PCA normalizes estimates of A and the factor loadings to satisfy r'r = I and assumes that —C1 = a2/. The large approximate dynamic factor deterioration in financial conditions when economic growth is high and inflation low may have different effects on the real economy than a deterioration in financial conditions when economic growth is low and inflation high. Our adjusted FCI is, thus, likely relevant for iso lating the source of the shock to financial conditions.1 That said, our FCI is a broader metric of financial sta bility because it captures the interaction of financial conditions and economic conditions. Combined, the two indexes could serve as usefiil policy tools by pro viding a sense of how tight or loose financial markets are operating relative to historical norms. Figure 1 plots our FCI and adjusted FCI. Interpreting the level of both requires a reference to some historical norm. The norm considered in figure 1 is the sample mean of each index, which provides a sense of the aver age state of financial conditions, or its long-term his torical trend. In this sense, a zero value for our FCI in figure 1 corresponds with a financial system operating 1Q/2011, Economic Perspectives BOX 2 (CONTINUED) Estimating our financial conditions indexes model framework relaxes this assumption, instead using vv the normalization that = I and accommodating cross-sectional heteroskedasticity, that is, Because of the varying frequencies of observa tion of the data in our FCI, we must also make two extensions to the EM algorithm prior to estimation. The first involves setting up the Kalman filter to deal with missing values as discussed by Durbin and Koopman (2001). The second modification involves including additional state variables that evolve deter ministically to adjust for the temporal aggregation issues caused by the varying frequencies of data observation. Here, we follow Aruoba, Diebold, and Scotti (2009) in their application of Harvey (1989) to data of varying frequencies of observation to augment the transition dynamics of the state-space model accordingly. Our adjusted FCI requires pretreatment of the data before application of the routine we just described. Each of the 100 financial variables is first regressed on current and lagged values of a measure of the business cycle— that is, the three-month moving average of the Chicago Fed National Activity Index (CFNAI-MA3)—and infla tion—that is, three-month total inflation as measured by the Personal Consumption Expenditures (PCE) at the historical average levels of risk, liquidity, and leverage. For our adjusted FCI, a zero value indicates a financial system operating at the historical average levels of risk, liquidity, and leverage consistent with economic conditions. In general, risk measures receive positive weights in each index, whereas liquidity and leverage measures tend to have negative weights. This pattern of increasing risk premiums and declining liquidity and leverage is consistent with tightening financial conditions, and pro vides us a basis for interpreting both indexes: Positive index values indicate tighter conditions than on average, and negative index values indicate looser conditions than on average. In addition, it is common for financial conditions indexes to be expressed relative to their sample standard deviations. We follow this approach to establish a scale for our FCI and adjusted FCI in figure 1. Measured in this way, an index value of 1.0 is associated with finan cial conditions that are tighter than on average by one Federal Reserve Bank of Chicago Price Index—with the number of current and lagged values in each regression chosen for each variable using the Bayesian Information Criterion. The independent variables of these regressions were transformed so as to match the frequency of observation of the dependent variable. For weekly variables, we assumed only lagged values enter the regression and that these values are constant over the weeks of the month because of the monthly frequency of observation for the CFNAI-MA3 and total PCE inflation. The standardized residuals from these regressions are then used to construct our adjusted FCI. Our 100 financial indicators consist of 47 weekly, 29 monthly, and 24 quarterly variables. The longest time series extends back to 1971, while the shortest begins in 2008. We estimate the EM algorithm on the unbalanced panel from the first week of 1971 through 2010. However, we only consider the estimates from the first week of 1973 onward. At this point, over 25 percent of the financial indicators we examine have complete time series. Because of the number of high-frequency indicators we examine, it is not until 1987 that 50 percent have complete time series. ’In addition, a small alteration in the least squares step is re quired to account for the fact that the unobserved components of the model must first be estimated. See Brave and Butters (2010a) for more information on the construction of the index. standard deviation. Similarly, an index value of-1.0 indicates that financial conditions are looser than on average by one standard deviation. It is important to note, however, that given the transformations described previously, direct compari sons across the two indexes are not valid. Instead, comparisons must be made with respect to how each captures financial conditions over time. For instance, our adjusted FCI is much less persistent, moving above and below its average value more frequently than our FCI. It is also the case that our adjusted FCI gives more emphasis to recent financial market disruptions, often putting them on par with the more volatile 1970s and 1980s. Instances can occur where adjusting for economic conditions produces a different interpretation of finan cial conditions than our FCI. Periods of high economic growth, such as the mid-1980s and late 1990s, often lead to an above-average adjusted FCI when our FCI is below average. Conversely, periods of high 25 FIGURE 1 Financial conditions indexes (FCI and adjusted FCI), 1973-2010 1Q /2 011, Econom ic Per spe ctiv es inflation, such as the 1970s and early 1980s, often lead to a below-average adjusted FCI when our FCI is above average. Systemically important indicators There are two ways to view the systemic relation ship expressed in each indicator’s weight: by its sign and by its magnitude. Risk measures with their gener ally positive weights and liquidity and leverage mea sures with their generally negative weights imply that increasingly positive values of the index capture periods of above-average risk and below-average liquidity and leverage. Conversely, increasingly negative values of the index capture periods where risk premiums are below average and liquidity and leverage are above average. The way in which leverage enters our indexes is in line with Adrian and Shin (2010), who find leverage is often procyclical (that is, it is positively correlated with the overall state of the economy). In this way, the process of deleveraging appears in the indexes as an indicator of deteriorating financial conditions. Unlike other methods, however, our estimation framework can potentially take into account that a buildup of leverage generates a tendency to reverse itself that depends on the degree of mean reversion that our FCI and adjusted FCI have shown over time. Taking into account the financial markets represent ed, we have segmented the financial indicators in our FCI and adjusted FCI into three categories: money markets (28 indicators), debt and equity markets (27), and the banking system (45). Table At in the appendix summarizes all 100 financial indicators in the form they enter both indexes; the indicators are listed in this order—from those with the largest positive weights to those with the largest negative weights within each category for our FCI. Because in our estimation method the weights are only identified up to scale, we have scaled them to have a unit variance in the table for ease of comparison. The money markets category is made up mostly of interest rate spreads that form the basis of most other financial conditions indexes.2 However, unlike for many of these indexes, we also include in this category measures of implied volatility and trading volumes of several money market financial products. Interest rate spreads and measures of implied volatility tend to receive positive weights, whereas trading volumes tend to receive negative weights. The implication of this pattern is that widening spreads, increasing vola tility, and declining volumes all constitute a tightening in money market conditions. Some of the interest rate spreads given the great est positive weights in our FCI include the one-month Federal Reserve Bank of Chicago nonfinancial A2P2/AA commercial paper credit spread, as well as the two-year interest rate swap and the threemonth Libor spreads relative to Treasuries. The first captures the risk premium for issuing short-term com mercial paper to less creditworthy borrowers. The re maining two indicators capture elements of liquidity and credit risk in the interest rate derivative and inter bank lending markets, respectively. The Merrill Lynch implied volatility measures for options and swaptions (MOVE and SMOVE) also receive large positive weights, whereas open interest in money market derivatives and repo market volume receive sizable negative weights. The former two indicators are, in a sense, measures of risk, while the latter two can be viewed as measures of liquidity and leverage. The debt and equity markets category comprises mostly equity and bond price measures capturing vol atility and risk premiums in their various forms. In addition to stock and bond market prices, we include in this category residential and commercial real estate prices, as well as municipal and corporate bond, stock, asset-backed security, and credit derivative market volumes. The latter measures capture elements of both market liquidity and leverage. In general, the indicators in this category follow the same pattern as the money market category, so that widening credit spreads, in creasing volatility, and declining volumes denote tightening debt and equity market conditions. In terms of equities, the largest positive weight in our FCI is given to the Chicago Board Options Exchange (CBOE) Market Volatility Index, commonly referred to as the VIX, which measures the implied volatility of the Standard & Poor’s (S&P) 500; the largest negative weight is given to the relative valuation of financial stocks in the S&P 500 (S&P Financials/ S&P 500). In terms of bonds, credit spreads such as the high yield/Baa corporate and financial/corporate enter strongly here with large positive weights; so do spreads relative to Treasuries or swaps for nonmortgage asset-backed securities (ABS), mortgage-backed securities (MBS), and commercial-mortgage-backed securities (CMBS). Swap spreads on credit derivatives for investment grade and high-yield corporate bonds— or credit default swaps (CDS), a measure of insurance protection tied to default—are also given sizable positive weights. The banking system category contains mainly survey-based measures of credit availability as well as accounting-based measures for commercial banks and so-called shadow banks, but a few interest rate spreads also appear in this category. The former indi cators are primarily measures of liquidity and leverage, but they also capture the risk tied to deteriorations in 27 FIGURE 2 Decomposition of variance explained by financial conditions indexes (FCI and adjusted FCI) ^B Money markets ^B Debt and equity markets Banking system Note: All values are in percent. credit quality. Of the interest rate spreads, the difference between the 30-year jumbo and conforming fixed-rate mortgages receives the largest positive weight, followed by the 30-year conforming mortgage/10-year Treasury yield spread. The Federal Reserve Board’s Senior Loan Officer Opinion Survey questions on loan spreads and lending standards all enter strongly into our FCI (mostly with large positive weights so that widening spreads and tighter standards reflect tighter conditions in the banking system), as do several other survey measures of busi ness and consumer credit availability. Depending on how these survey measures are expressed, some receive large negative weights; but in each case, declining avail ability coincides with fighter banking system conditions. The Credit Derivatives Research Counterparty Risk Index, measured as the average of the CDS spreads of the largest 14 issuers of CDS contracts, also receives a large positive weight, with the remaining weight split roughly evenly between measures of credit quality and commercial and shadow bank lending and leverage. All of these measures capture the inherent risks to the stability of the financial system posed by the potential collapse of commercial and shadow bank entities. 28 Differences arise in the relative systemic impor tance of several indicators when considering the impact of economic conditions in the estimation of the indicator weights. Figure 2 helps to explain these differences. Measures of the health of the banking system capture 41 percent of the variation explained by our FCI, fol lowed by money market measures at 30 percent and debt and equity market measures at 29 percent. After performing the same calculation on our adjusted FCI, we note that money market measures now dominate at 54 percent, with debt and equity market measures accounting for 26 percent and the banking system measures accounting for 20 percent. Thus, the primary effect of adjusting for economic conditions appears to be the reduction in importance of banking system measures. The survey-based indicators within the banking system category, in particular, show the largest declines in weight. A lower weight in this case indicates that much of the variation in these indi cators can be explained by changes in either economic activity or inflation over time. A secondary effect, visible in table Al in the appendix, is the addition of weight to certain measures of liquidity and leverage—that is, corporate bond and asset-backed security issuance, the net notional value of credit derivatives, and several commercial and shadow bank leverage measures. 1Q/2011, Economic Perspectives It is likely that some of this result, shown in figure 2, stems from the fact that most of the previously men tioned measures are available at a weekly frequency Our adjustment for economic conditions is more like ly to account for medium-frequency rather than highfrequency variation. However, an examination of the weights in table Al suggests that this cannot be the sole explanation. Several weekly money market mea sures receive greater weight—for example, the threemonth London interbank bid (Eurodollar) and offered (TED) rate spreads; but there are also a number of weekly debt and equity market measures that receive less—for example, the high yield/Baa corporate bond, CMBS, and various credit derivative swap spreads, as well as the VIX. Gauging financial stability One way to judge the validity of our indexes as measures of financial stability is to follow the narra tive approach and link their values to significant events in U.S. financial history. To illustrate this point, we plot our FCI and adjusted FCI in figure 3, highlight ing prominent historical events.3 Each panel of figure 3 depicts a decade of the index. Events are labeled with text boxes and arrows directed toward a specific week of both indexes denoted by a circle marker. Overall, significant periods of crisis in financial history are well captured by both indexes, as are periods of relative calm. There are subtle differences, however, between the indexes around the time of several of the major events marked in figure 3. The first is clearly seen in panel A of figure 3 during the 1973-75 period that saw disruptions in equity markets and the failures of several large banks. In general, our adjusted FCI is quicker than our FCI to note both the onset and end of pressures—as financial conditions began to deteri orate prior to the 1973-75 recession and as they be gan to recover sooner than the real economy. For most of the rest of the 1970s, both indexes indicate very similar financial conditions. However, by the end of the decade and into the early 1980s, as shown in panels A and B of figure 3, differences again emerge. The large swings in economic activity and inflation during these periods lead the adjusted FCI to be much more volatile, often swinging from well be low zero to well above it very quickly. At their peak levels, both indexes are still very similar, capturing very well the major events of this period. From the mid-1980s through the end of the decade, differences between the two indexes are much smaller (panel B of figure 3). Two events, however, stand out during this period of strong growth and disinflation: the resolution of Continental Illinois National Bank Federal Reserve Bank of Chicago and Trust Company and the “Black Monday” stock market crash of 1987; the adjusted FCI puts more weight relative to earlier events on each compared with the FCI. The adjusted FCI is also quicker to note above-average tightness in response to the U.S. savings and loan crisis and quicker to recover from the crisis after accounting for the 1990-91 recession (see panels B and C of figure 3). From the mid-1990s through the end of the decade (panel C of figure 3), the adjusted FCI consistently indicates financial conditions relative to economic con ditions either about average or tighter than on average. In contrast, only after the Russian debt default, the sub sequent collapse of Long-Term Capital Management, and the run-up to Y2K (the year 2000 software problem) does the FCI indicate financial conditions that are tighter than on average. During this period, the adjusted FCI additionally picks up the relative tightening in financial markets surrounding the Mexican peso devaluation and Asian financial crisis (around the time of the devalua tion of the Thai baht). Despite small differences surrounding the crash of the NASDAQ Stock Market and the corporate accounting scandals of the early 2000s (panel D of figure 3), both indexes generally indicated conditions looser than on average through the early part of the previous decade. Beginning in late 2005, the adjusted FCI moved closer to its average, while the FCI remained well below its average. The recent financial crisis appears at about the same time in both indexes, from mid-2007 through mid-2009, while the recovery reg isters a little later in the adjusted FCI. More recently, as seen in figure 1 (p. 26), both indexes demonstrate that the financial system has healed significantly. Financial conditions by either measure, however, remain tighter than they were be fore the crisis. They have also been responsive to the European sovereign debt concerns that began in the spring of 2010 and the slowdown in economic activity throughout the summer months of 2010. In fact, our adjusted FCI breached its average level in the summer of 2010 before easing again during the rest of 2010. Our historical analysis shows that persistent de viations in the interpretation of our two indexes con tain useful information. The adjusted FCI is, in some sense, a forward-looking indicator of the FCI. When financial conditions are out of balance with economic conditions for an extended period, a correction in the FCI tends to result. Whether or not this result is due to the influence of the policy actions taken during these periods or other economic forces is beyond the scope of the analysis here. However, we refer the reader to Brave and Butters (2010a) and Brave and 29 FIGURE 3 Financial conditions indexes (FCI and adjusted FCI) and prominent historical events, 1973-2009 A. 1970s standard deviations from trend 1Q /2 011, Econom ic Per spe ctiv es 1973 Federa l Res erv e Bank of Chicag o FIGURE 3 (continued) Financial conditions indexes (FCI and adjusted FCI) and prominent historical events, 1973-2009 B.1980s standard deviations from trend FIGURE 3 (continued) Financial conditions indexes (FCI and adjusted FCI) and prominent historical events, 1973-2009 C. 1990s standard deviations from trend 6 4 -2 - 1Q /2 011, Econom ic Per spe ctiv es -4 1990 ’91 ’92 ’93 ’95 ’94 FCI ’96 Adjusted FCI ’97 ’98 ’99 Federa l Res erv e Bank of Chicag o FIGURE 3 (continued) Financial conditions indexes (FCI and adjusted FCI) and prominent historical events, 1973-2009 D. 2000s standard deviations from trend _____ FCI ... Adjusted FCI Genay (2011) for more rigorous analyses of the FCI and adjusted FCI. Forecasting economic conditions Another test of our indexes is their ability to pre dict the impact of changes in financial conditions on future economic activity. We follow the forecasting framework of Hatzius et al. (2010); but we refine their approach in two ways: 1) by concentrating on the por tion of our FCI that cannot be explained by its historical dynamics and 2) by including as explanatory variables high-frequency nonfinancial measures of economic activity, such as the Chicago Fed National Activity Index (CFNAI).4 We refer to the portion of our FCI that cannot be predicted based on its historical dynamics as the FCI residual. The FCI residual corresponds with the error term, v(, from the transition equation of our dynamic factor model (described in detail in box 2), where we follow the convention described previously for our FCI and scale it by its sample standard deviation. Because the FCI captures an element of financial conditions that also depends on economic conditions, systematic changes in the FCI over time reflect the historical response of financial conditions to past changes in financial and economic conditions. The FCI residual, therefore, reflects the deviation of financial conditions from this historical pattern. It is this aspect of the FCI residual that we find appealing as an explanatory variable for future economic activity; in this regard, we prefer the FCI residual over the adjusted FCI, which captures only the deviation of financial conditions from economic conditions. Hatzius et al. (2010) frame the use of their adjusted index as a method of focusing purely on the impact of financial shocks on economic activity. We, instead, use our FCI because it also contains information on economic shocks. We then control for whether this information is in addition to that found in high-frequency nonfinancial measures of economic activity. To demonstrate the ability of the FCI residual to predict future economic conditions and for the sake of comparison with the adjusted FCI, we conducted a pseudo out-of-sample forecasting exercise. Our mixedfrequency forecasting regressions incorporated lagged values of quarterly forecast variables taken from the U.S. Bureau of Economic Analysis’s national income and product accounts (NIPA), as well as current and lagged values of the three-month moving average of the CFNAI alone or in combination with the 13-week moving average of one of the following sampled at the end of each month: the FCI residual, adjusted FCI, or 34 adjusted FCI residual (which is the portion of the ad justed FCI unexplained by its historical dynamics).5 The CFNAI’s three-month moving average serves as our reference point in evaluating the marginal in formation content of our measures of financial condi tions over high-frequency nonfinancial measures of economic activity. It is a summary measure of 85 in dicators constructed using PCA on data for production and income; employment, unemployment, and hours; personal consumption and housing; and sales, orders, and inventories.6 The CFNAI has been used in the past to forecast economic growth and inflation by Stock and Watson (1999) and Brave and Butters (2010b), among others. Our forecasting regression takes the following form: Y,+l~ Y,= « + t PM+1_,.+f yyCFW4/,+1_y i=l 7=1 +Z SkFCIl+i_k +s,+h, 7=1 where T refers to the natural log of a particular NIPA data series, CFNAI indicates the three-month moving average of the CFNAI, and FCI is the 13-week moving average of either the FCI residual, adjusted FCI, or adjusted FCI residual. The explanatory variables were aligned with the NIPA data in the last month of each quarter (t) to match frequencies so that the index / represents a quarter (or three months) and the indexes j and k both represent months. To construct forecasts, we began with data from 1973 :Q 1 through 1984:Q4.7 One quarter’s worth of data was then added on a recursive basis and forecasts made at a horizon (//) of one, two, four, and six quarter(s) ahead until the end of our data in 2010:Q2. The advan tage of this framework is that it mimics the production of forecasts in real time (minus the impact of data revisions). In this way, we can account for model uncertainty. To allow for the further possibility of a change in lag structure over time, we had each recur sive regression incorporate the Bayesian Information Criterion lag selection method.8 For an evaluation criterion, we used the meansquared forecast error (MSFE) statistic computed from our sample of forecasts from 1985;Q1 through 2010:Q2 expressed relative to the similar statistic based on fore casts computed using only lagged quarterly growth rates of the NIPA variables. This ratio provides a test of model fit, so that a value less than 1 indicates an improvement in forecast accuracy relative to an autoregressive base line for each NIPA variable. The MSFE statistic summa rizes two elements in our pseudo out-of-sample context: the improvement in fit from incorporating the CFNAI 1Q/2011, Economic Perspectives TABLE 1 Pseudo out-of-sample relative MSFE ratios h CFNAI FCI residual Adjusted FCI Adjusted FCI residual 0.81 0.82 0.90 0.88 0.88 1.06 1.07 1.07 0.85 0.96 1.00 1.01 0.91 0.88 0.94 1.02 1.03 1.06 1.17 1.20 0.96 0.97 1.10 1.11 0.76 0.67 0.75 0.79 0.79 0.81 0.90 0.89 0.78 0.73 0.85 0.84 0.92 0.99 1.23 1.30 1.11 1.19 1.29 1.37 1.13 1.18 1.33 1.35 1.03 0.97 0.94 0.97 1.10 1.01 0.98 1.03 1.07 1.01 0.99 1.02 A.

The forecasted variable is listed at the top of each panel. Column headings for each panel denote the additional variable added to the baseline model: The CFNAI is the three-month moving average of the Chicago Fed National Activity Index and is included in all four specifications. The FCI residual is the 13-week moving average of the portion of the financial conditions index unexplained by its historical dynamics, the adjusted FCI is the 13-week moving average of the financial conditions index adjusted for economic conditions, and the adjusted FCI residual is the 13-week moving average of the portion of the adjusted financial conditions index unexplained by its historical dynamics—these three individually serve to augment the model including the CFNAI. The rows in each panel denote the forecast horizon (/?) measured in quarters beyond the end of the sample period. The sample period is recursive beginning in 1973:Q1 and rolling forward from 1985:Q1 through 2010:Q2. PCE denotes personal consumption expenditures.

Table 1 summarizes the results for nine NIPA variables all expressed in real, or constant price, terms. Gross domestic product (GDP) in panel A is the broad est measure we consider, but we also examine several of its components. Gross domestic purchases (panel B) exclude exports, and thus solely capture domestic de mand. Final sales (panel C) remove the influence of changes in inventories. Nonfarm private inventories, nonresidential investment, and residential investment (panels D, E, and F) form the basis of the investment Federal Reserve Bank of Chicago component of GDP we consider, and personal expendi tures on durables, nondurables, and services (panels G, H, and I) account for consumption. We do not directly consider government spending or exports. A few observations are readily apparent from this table. First, including the CFNAI in our forecasting regressions on NIPA data results in a substantial im provement in forecast accuracy (MSFE ratios less than 1) for GDP and measures of business investment, par ticularly at shorter horizons. Adding the FCI residual improves upon these initial forecasts at every horizon and for every variable, with the magnitude of improve ment ranging from just less than 1 percent to 22 percent.9 In contrast, adding the adjusted FCI rarely improves on the forecasts based on the CFNAI alone; and the 35 FIGURE 4 Two-quarter-ahead forecasts of real gross domestic product growth 1Q /2 011, Econom ic Per spe ctiv es ——— Chicago Fed National Activity Index’s three-month moving average (CFNAI) • ••••• CFNAI and financial conditions index (FCI) residual’s 13-week moving average ---------CFNAI and adjusted FCI residual’s 13-week moving average Actual Source: Authors’ calculations based on data from the U.S. Bureau of Economic Analysis, National Income and Product Accounts of the United States, from Haver Analytics. forecasts augmented with the adjusted FCI are less accurate than the forecasts augmented with the FCI residual in nearly every case. The FCI-residual forecasts are also superior when compared with the adjusted-FCI-residual fore casts in nearly every case. However, the adjusted-FCIresidual forecasts are often superior to the forecasts based on the CFNAI alone and those augmented with the adjusted FCI. In this respect, our results suggest how to improve the ability of the adjusted FCI to fore cast future economic activity—the key is to focus on the portion of the adjusted FCI that is not explained by its historical dynamics. This potential improve ment is made by our extension of the index con struction methodology of Hatzius et al. (2010) to a dynamic framework. The results in table 1 also suggest that the FCI residual contains information on future economic activity in addition to that found in high-frequency nonfinancial measures of economic activity. There is, however, considerable variation in the forecasting performance of the FCI residual over time not shown in table 1. Much of the gains in forecast accuracy are concentrated in the recent period. Despite this fact, the inclusion of the FCI residual in our forecasting regressions rarely significantly worsens the forecast based on the CFNAI alone, so that it comes with little cost but potentially large benefits. Figure 4 captures an instance of the small cost, large reward nature of including the FCI residual in our forecasting regression. It depicts actual real GDP growth at a two-quarter horizon and the forecasts for this measure based on the CFNAI’s three-month moving average, as well as these forecasts including the 13-week moving average of the FCI residual or adjusted FCI residual. Differences prior to the recent crisis tend to be small. During these periods, sometimes the forecast including the FCI residual is marginally superior and sometimes it is not. Federal Reserve Bank of Chicago The forecast series begin to consistently deviate from one another in the second half of 2007, when the crisis started to unfold. Throughout the recent recession and recovery, the forecast including the FCI residual has more consistently tracked actual real GDP growth than any of the other forecasts we consider. At times during this period, however, the adjusted-FCIresidual forecast has been superior. The FCI-residual forecast’s dominance over the adjusted-FCI-residual forecast over the entire period is due in large part to it more quickly picking up the beginning of the recent re cession and the magnitude of the subsequent recovery. Conclusion Our newly constructed financial conditions in dexes can serve as tools for both policymakers and financial market participants in gauging the current state of financial markets. Computed over a long time horizon and from a large sample of financial indicators of different frequencies, these indexes provide a time ly assessment of how tightly or loosely financial mar kets are operating relative to historical financial and economic conditions. As a measure of financial stability, our indexes exhibit several essential characteristics. Known periods of financial crisis correspond closely with peak periods of tightness in each index, and the turning points of each index coincide with well-known events in U.S. financial history. Furthermore, our indexes contain information on future economic activity beyond that found in nonfinancial measures of economic activity. Our indexes are also unique in that they derive from an estimation method that captures both the systemic importance of traditional and new financial markets and the dynamic evolution of overall finan cial conditions. In the future, we plan to develop this framework further in order to better understand the channels through which changes in financial condi tions affect economic activity. 37 NOTES ‘Hatzius et al. (2010) also construct a similar version of their index of financial conditions and relate it to changes in the federal funds rate over time. We have found very similar results to theirs; our adjusted FCI is significantly correlated with measures of monetary policy, though we have not documented this here. See Brave and Genay (2011), who relate monetary policy during the recent crisis to the adjusted FCI, for more information. 2Most of our 100 financial indicators have become standard fare in the financial press as a result of the recent financial crisis. Rather than describe each in further detail, we refer interested readers to the useful summaries found in Nelson and Perli (2007), Hakkio and Keeton (2009), and Hatzius et al. (2010). 3The literature on financial crises is quite extensive. The following works are a few of those that were instrumental in constructing our timeline of events: Federal Deposit Insurance Corporation (1984, 1997), Reinhart and Rogoff (2008), Schreft (1990), Minsky (1986), Spero (1999), Laeven and Valencia (2008), Carron (1982), and El-Gamal and Jaffe (2008). 5We use smoothed measures of the explanatory variables when appropriate to approximate the quarterly frequency of the NIPA variables being forecasted. 6For more details on the CFNAI, including its 85 indicators, see www.chicagofed.org/digital_assets/publications/cfnai/background/ cfnai_background.pdf. 7To be technically correct, we varied the endpoint of the initial sample based on the forecast horizon so that the first forecast always began at 1985:Q1. 8Maximums of I = 5 quarters and J,K= 6 months were used in its calculation. 9In the case of nonfarm private inventories, there is one instance in table 1 where the improvement is not apparent because of the rounding in this table. 4Hakkio and Keeton (2009) also use the CFNAI to make similar comparisons. 38 1Q/2011, Economic Perspectives Financial indicator Transformation Frequency Haver/Bloomberg*/ Call ReportA

Crowley and Xi Luo Introduction and summary In April 2009, the world economy appeared to be in a free fall. Global trade in goods and services had fallen 15.8 percent over the final two quarters of 2008 and the first quarter of 2009.1 This world trade collapse had been the largest three-quarter decline of the past 40 years. Five months earlier, in November 2008, leaders of the Group of Twenty (G-20)—20 large economies that make up roughly 85 percent of the world’s economic activity2—had met in Washington, DC, and pledged to stabilize the world financial system and improve coordination of macroeconomic responses to the global financial crisis.3 Despite monetary easing and fiscal stimulus in many economies, real economic activity continued to deteriorate over the next few months. Reconvening in April 2009 in London, the G-20 leaders had a full agenda, which included the following topics: the role of fiscal stimulus to promote recovery; the reform of banking and financial regulation; and the strengthen ing of the International Monetary Fund and the multi lateral development banks (MDBs), such as the World Bank Group. In addition, even though the world was in the midst of an unprecedented globalfinancial crisis, the problem of international trade was unusually prominent on the agenda. Among the commitments made by the G-20 in London, two directly addressed international trade. First, leaders promised to “ensure availability of at least $250 billion over the next two years to support trade finance through our export credit and investment agencies and through the MDBs.”4 Second, they reaf firmed a commitment made at the earlier Washington, DC, summit to refrain from raising new barriers to trade in goods and services. Finally, as part of the general strategy to restore economic growth, they pointed out that “an unprecedented and concerted fiscal expansion” among the member economies would total $5 trillion 44 by the end of 2010.5 If declining trade simply reflected declining economic activity, this fiscal expansion would be expected to have an important impact on global trade. Previous work6 has documented what many economists now refer to as the Great Trade Collapse of 2008-09, and has analyzed its potential causes. In this article, we review not only the unprecedented collapse of world trade in 2008-09, but also the equally dramatic trade recovery that took place in 2009-10. We look at these events in a historical context, by comparing them to previous trade contractions and recoveries. To gain a better understanding of the links between trade and broader economic conditions, we look at changes in the trade-to-gross-domestic-product (GDP) ratios of major economies across the globe be fore, during, and after the Great Trade Collapse. Then, we discuss three primary hypotheses that explain the trade collapse: 1) a decline in aggregate demand for all goods; 2) difficulties in obtaining trade finance; and 3) rising trade barriers. We consider how three distinct policy actions—fiscal stimulus, funding for trade finance, and a commitment to refrain from trade barriers—might have affected both the collapse and the subsequent re covery. Finally, we review four prominent examples from the large literature examining the contributing factors to the recent collapse of global trade. Determining the relative degree to which the var ious demand- and supply-side factors contributed to the Great Trade Collapse is important for formulating the optimal policy response. Economists would like to deter mine if there are market failures or counterproductive Meredith A. Crowley is a senior economist and Xi Luo is an associate economist in the Economic Research Department at the Federal Reserve Bank of Chicago.

If research finds that weak domestic demand (resulting from falling consumer income, stronger preferences for saving over consumption, or high unemployment) is the prime cause of the sharp fall in trade, then there is not a clear mandate for gov ernment intervention except, perhaps, actions to address the overall recession. In contrast, if research shows that trade finance problems are slowing down world trade, the appropriate policy response might be inter ventions by the government or nongovernmental or ganizations in certain financial or insurance markets. For example, governments could subsidize the price of payment instruments, export credit insurance, or even working capital loans. Finally, if analysis shows that the government’s tariffs on imports or nontariff barriers to trade are behind a sharp decline in trade, then the best policy solution would be the removal of these government interventions from international goods markets. According to the literature, the global collapse in economic activity explains between 35 percent and 80 percent of the Great Trade Collapse. The analysis we perform in this article estimates that declining aggregate demand explains 35-50 percent of the Great Trade Collapse. With regard to the recovery, our analysis finds a quantitatively larger puzzle; rising aggregate demand explains only 25-40 percent of the recovery in imports. The findings of the literature on the role of trade finance in the collapse are mixed, with one paper finding that tighter financial conditions likely had a moderate negative effect on trade volumes during the financial crisis of 2008-09. Further, in this article, we document the evolution of antidumping trade restric tions imposed by the United States and Canada over the past 40 years and conclude that there was no sig nificant increase in border restrictions by these two countries in 2008 or 2009. Thus, trade protection by these countries was not a cause of the collapse. In terms of the dramatic recovery in trade, the absence of explicit border barriers at least allowed the recovery to progress unhindered. The conclusion that changing aggregate demand was the major cause of both the dramatic col lapse in trade volumes in 2008-09 and the spectacular recovery in 2009-10 suggests that of all the policy actions, fiscal stimulus likely had the largest impact on the trade recovery. What was the Great Trade Collapse? In this section, we document some stylized facts about the Great Trade Collapse of 2008-09 and the sub sequent recovery. Panel A of figure 1 documents the timing and magnitude of the Great Trade Collapse. Federal Reserve Bank of Chicago The plotted series is the seasonally adjusted quarterly level of world trade measured in trillions of 2005 U.S. dollars. World trade of goods and services is defined as (A + A/)/2, where X is world exports of goods and services and M is world imports of goods and services. The V-shaped path toward the end of panel A corre sponds to the collapse in world trade during the period 2008:Q2-2009:Q2 and the equally rapid recovery from 2009:Q2 onward. This world trade series from the Organisation for Economic Co-operation and Develop ment (OECD), which starts in 1968:Q2, demonstrates a clear upward trend. The level of world trade in 2010:Q3 is more than 15 times the level in 1968:Q2. While international trade has been trending upward for more than four decades, with an annual growth rate of 6.48 percent, episodes of contraction have not been uncommon. Between 1974:Q2 and 1975:Q2, the world trade level declined by 7.65 percent; between 198O:Q1 and 1980:Q3, it slid by 3.34 percent; between 1981:Q4 and 1982:Q4, it slipped by 3.12 percent; and between 2000 :Q4 and 2001:Q4, it decreased by 3.51 percent. The Great Trade Collapse, which occurred between 2008:Q2 and 2009:Q2, was more severe than all the previous tumbles—the volume of world trade plummeted by 17.20 percent from peak to trough. In panel B of figure 1, the log of world trade in trillions of 2005 U.S. dollars is plotted. This series displays a clear linear trend. Notice that during the 2000s, trade growth stood above the trend line until the collapse of 2008-09. Although a rapid recovery began after 2009:Q2, world trade has yet to return to its long-run linear trend. Next, we turn to the United States. Panel A of figure 2 shows real seasonally adjusted U.S. imports and exports. Like the rest of the world, the United States has seen fast growth in trade over the past few decades. From 1965 through 2010, U.S. imports grew at an annual rate of 6.03 percent and U.S. exports grew at an annual rate of 5.92 percent. During the Great Trade Collapse (2008:Q2-2009:Q2), U.S. real imports declined by 18.3 percent while U.S. real exports dropped by 14.7 percent. Given the rapid growth in trade over the previous five decades, the magnitude of the col lapse in exports and imports was truly astonishing. Panel B of figure 2 shows the log levels of U.S. real imports and exports, which both display linear upward trends over time. Notice that the bumps and wiggles in the series for the United States are more apparent than in their counterparts for world trade in panel B of figure 1. These differences between world trade and U.S. trade measures are due to the fact that in world trade flows, a decline in one country’s trade volume is often offset by growth in another’s. 45 FIGURE 1 World trade, 1968-2010 A.

Trade contractions and recoveries in historical perspective How does the most recent trade collapse compare with previous episodes of trade contraction? And how does the current recovery in trade compare with previous recoveries? In figure 3, we present “spider graphs” that allow us to compare the magnitude and speed of differ ent trade contractions and recoveries. Panel A of figure 3 presents several U.S. trade contractions and recoveries, while panel B of figure 3 presents trade contractions and recoveries for the world. In both panels A and B of figure 3, we normalize real, seasonally adjusted, quarterly data on trade, defined as (X + M)I2, to be equal to 100 in the quarter identified as the trough of each U.S. trade contraction. We identified the following quar ters as the troughs of U.S. episodes of trade contraction and recovery: 1975:Q2, 1980:Q3, 1982:Q4, 1991 :Q1, 2001:Q4, and 2009:Q2. Next, we investigate what happened to the volume of U.S. and world trade four quarters before and five quarters after these identified nadirs for U.S. trade. Numbers on the horizontal axes represent the number of quarters before and after the trough date; therefore, the number zero corresponds to the troughs. Numbers to the left of zero generally Federal Reserve Bank of Chicago correspond to a period of decline in trade volume. Anal ogously, numbers to the right of zero generally corre spond to a period of recovery in trade volume. We refer to each episode of trade contraction and recovery by its trough date. In both panels, the solid black line stands out. The black lines (representing the 2009 :Q2 episode) depict the changes in trade volume during the Great Trade Collapse of 2008-09 (and the subsequent re covery) for the United States and the world in panels A and B, respectively. A closer look at these spider graphs reveals the following facts. First, for both the United States and the world, the recent trade collapse is the most severe decline in trade since the late 1960s, in terms of both magnitude and speed. Notice that for both the United States and the world, sustained trade declines do not last more than four quarters. For the United States, the 1975:Q2, 1982:Q4, and 2001:Q4 episodes all have four quar ters of contraction. In contrast, for the 1980:Q3 and 1991 :Q 1 episodes in the United States, contractions lasted for only two quarters. The patterns of contraction in world trade are almost identical to those in the U.S. trade. An exception is the 1991 :Q 1 episode in which world trade never experienced a decline. 47 Second, despite its huge magnitude, TABLE 1 the Great Trade Collapse does not stand Averages of annualized quarterly growth rates out as more protracted than previous epi of trade sodes.

Third, let us take a look at the right hand side of each panel in figure 3 and examine the recovery that followed each collapse. We notice that following the Figure 4 disentangles the U.S. episodes of trade con nadir of the Great Trade Collapse (2009 :Q2), despite traction and recovery into spider graphs of imports a remarkably fast recovery rate, as of2010:Q2, both (panel A) and exports (panel B).

However, it is not clear from this 2009:Q2 episode.

On the one hand, a recovery exports in order to understand the Great Trade Collapse of 17.8 percent for the 2009:Q2 episode has been much and the subsequent recovery from another angle. 48 2Q/2011, Economic Perspectives FIGURE 4 U.S. trade contractions and recoveries: Imports and exports B.

Next we turn to the export side in panel B of figure 4. Note that the Great Trade Collapse and the recovery following it (the 2009:Q2 episode) had the steepest and most symmetric V-shaped path around the trough date relative to all previous episodes. This makes the Great Trade Collapse and subsequent recovery look unique. Over the four quarters before the 2009:Q2 trough date, the average of the annualized quarterly growth rates of exports was -13.9 percent, the largest rate of decline seen over the past four decades. The recovery over the five quarters after the 2009:Q2 trough date has been fast, with an average of the annualized quarterly growth rates of 12.7 percent. The momentum of the export recovery was rapid in the beginning but gradually faded. The export series during the Great Trade Collapse and subsequent recovery features a quick collapse and a quick rebound. The export contractions in the 2001 :Q4 and 1982:Q4 episodes look similar to that of the 2009 :Q2 episode, although both of the earlier episodes feature slow Federal Reserve Bank of Chicago recoveries. In contrast, the 1975;Q2, 1980:Q3, and 1991 :Q 1 episodes do not have V-shaped paths. Take the 1975;Q2 episode, for example. During the collapse period, exports slid for a quarter, rebounded for two consecutive quarters, and then declined for two more quarters (past the trough date of imports for that epi sode). One quarter into the recovery, a brief reversal set in before a two-quarter rally that finally brought the export volume back to the level of 1974:Q2. Exports in the 1980:Q3 and 1991:Q1 episodes experienced little or no decline. Therefore, the brief trade contractions in the 1980:Q3 and 1991 :Q1 episodes can be attributed almost exclusively to contractions in imports. To summarize, the behavior for U.S. imports dur ing the Great Trade Collapse and the subsequent recov ery look similar to that of previous episodes. However, the V-shaped pattern of U.S. exports during the Great Trade Collapse and the subsequent recovery bears little resemblance to the behavior of exports in previous epi sodes. The unique path of exports during the 2009:Q2 episode appears to be driven by the strength of the 2008-09 global recession, which we explore in more detail in the next section. 49 Changes in trade and GDP Trade volume usually rises or falls in accordance with the direction of the general economy, so we want to examine this interaction. For U.S. trade levels, if we refer to figure 2 (on p. 46), for example, we see that trade contractions usually occur during recessions. How do we think of a trade contraction in the context of broader economic conditions? For any country, by summing up imports and exports and then dividing this quantity by GDP, we obtain that country’s trade-toGDP ratio. Multiplying by 100 allows us to express this ratio as a percent. Figure 5 shows the nominal trade-to-GDP ratios of the United States, France, Japan, and Germany over the past few decades. Let us focus on the U.S. experience plotted in panel A of figure 5. This ratio was 8.85 percent in 1965:Q1 and peaked in2008:Q3 at 31.88 percent. The upward trend in the evolution of this ratio indicates that the growth in trade volume has outpaced the growth in GDP over the past few decades; trade’s role in the broader economy has expanded steadily. The trade-toGDP ratio can be thought of as a measure of the open ness of an economy to trade. The fact that the trade-toGDP ratios for the United States, France, Japan, and Germany have all been trending upward over time shows that these countries have become more and more open to trade as part of their economic activities. This rise in openness is often referred to as globalization. Each country’s path to globalization is subject to its own historical idiosyncrasies. For example, the declines in the United States’ trade-to-GDP ratio occur close to U.S. recessions. During the period 1974:Q4—1975:Q3, around the time of the first oil crisis, the trade-to-GDP ratio decreased from 17.6 percent to 15.4 percent. Around the time that the dot-com bubble burst, in the period 2000:Q3-2001:Q4, the trade-toGDP ratio decreased from 26.3 percent to 22.0 percent. Finally, around the time of the global financial crisis, during the period 2008:Q3-2009:Q2, the trade-to-GDP ratio plummeted from 31.9 percent to 24.1 percent. For France (figure 5, panel B), fluctuations in the trade-to-GDP ratio follow a similar pattern to that observed for the United States. Starting at 26.3 percent in 1965:Q1, France’s trade-to-GDP ratio increased steadily over time, reaching 43.7 percent in 1974:Q3. When the oil shock set in, the trade-to-GDP ratio slid to 35.9 percent in 1975:Q3, and it did not surpass the pre-collapse level until 1980:Q 1—five and a quarter years after the trough. For France, whenever there is a drop in the trade-to-GDP ratio, it takes a relatively long time to recover. France experienced a plodding recovery from the trade contraction of the early 2000s. In 2008:Q3, France’s trade-to-GDP ratio stood at 50 56.6 percent, but it was crushed to 47.3 percent within three quarters. For France, the Great Trade Collapse appears to have precipitated a dip in the trade-to-GDP ratio following a relatively weak recovery from the earlier decline that coincided with the United States’ dot-com recession. Turning to Japan (figure 5, panel C), we see that the nominal trade-to-GDP ratio started from almost 30 percent in the early 1980s. This ratio dropped dras tically following the 1985 Plaza Accord, under which the Japanese yen started to appreciate against other major world currencies. Japan’s trade-to-GDP ratio dropped from 27.3 percent in 1984:Q4 to 16.8 percent in 1988:Q1. After rising for a few years, this ratio took another dip in the early 1990s, when it declined to a low of 15.6 percent in 1993:Q4. Following that dip, the trade-to-GDP ratio recovered steadily. Since 2001:Q4, Japan’s trade-to-GDP ratio had risen quickly, to a peak in 2008:Q3 of 38.6 percent. During the Great Trade Collapse, the trade-to-GDP ratio took a nose dive. Four quarters after the trough in 2009:Q2, Japan’s trade-to-GDP ratio had recovered only about half of the lost ground, standing at 30.0 percent. Germany’s trade-to-GDP ratio (figure 5, panel D) has trended upward, starting from 39.5 percent in 1968:Q1 to reach a peak of 90.9 percent in 2008:Q3. The reunification of Germany in the early 1990s knocked this ratio down from 63.1 percent in 1990:Q4 to 44.3 percent in 1993:Q4. Since then, the openness of Germany’s economy to trade had increased signifi cantly until the Great Trade Collapse. After peaking in 2008:Q3, Germany’s trade-to-GDP ratio fell to 74.6 per cent in 2009 :Q2, before beginning a sharp recovery. Examining the experiences of four major world economies displayed in figure 5, we conclude that in ternational trade has become more and more important to the global economy over time. What caused inter national trade to grow so explosively? In the post-World War II era, several factors have facilitated this meteoric growth in international trade: 1) the decline in tariffs under the General Agreement on Tariffs and Trade/ World Trade Organization (GATT/WTO) system7 (Crowley, 2003; and Subramanian and Wei, 2007), as well as a number of preferential trade agreements; 2) the decline in transportation costs (Hummels, 2001, 2007; and Levinson, 2006); 3) the rise of vertical spe cialization8 facilitated by the first two factors (Yi, 2003); and 4) the decline in communication costs (Freund and Weinhold, 2000). Given the rising openness to trade around the world depicted in figure 5, the Great Trade Collapse stands out not only because of its magnitude, but also because it ap pears to have been highly synchronized across countries. 2Q/2011, Economic Perspectives FIGURE 5 The ratio of trade to gross domestic product (GDP) for selected countries B.

Let us now examine the synchronicity of the Great Trade Collapse and the subsequent recovery by reviewing the experience of a broader range of coun tries. Figure 6 is a scatter plot of the percentage change in trade versus the percentage change in real GDP over the period 2008:Q2-2009:Q2 for 29 countries.9 Three important facts emerge from this picture. First, the decline in trade was broadly spread across this entire set of countries. During this period, the least affected country plotted, that is, Brazil, had a change in trade of more than -7.5 percent. The most affected country, that is, Mexico, had a change in trade of-26.1 percent. The United States’ trade collapse, Federal Reserve Bank of Chicago amounting to a change of-15.0 percent, fell right in the midrange of this cross section of countries. Second, with the exception of Australia, Poland, India, and Brazil, all countries displayed here experi enced declines in their GDP as well. Mexico again led the group, with a change of-10.0 percent. The United States experienced a -4.1 percent change in its GDP. Among the larger economies, Japan experienced a -5.9 percent change in GDP (as well as a -25.0 percent change in trade). Third, a fitted line through this scatter plot has a slope of 0.96, which indicates that a 1 percent decline in GDP is associated with a 0.96 percent decline in 51 FIGURE 6 The change in real trade vs. the change in real GDP during the Great Trade Collapse -10 -5 0 percentage change in real GDP AUS—Australia DEN—Denmark GRE—Greece KOR—South Korea AUT—Austria BRA—Brazil ESP—Spain FIN—Finland HUN—Hungary IND—India MEX—Mexico NED—Netherlands BEL—Belgium CAN—Canada FRA—France GBR—United Kingdom ISL—Iceland ITA—Italy NZL—New Zealand NOR—Norway CZE—Czech Republic GER—Germany JPN—Japan POL—Poland POR—Portugal SVK—Slovakia SUI—Switzerland TUR—Turkey USA—United States of America Notes: Both the changes in real trade and real gross domestic product (GDP) are measured over the period 2008:02-2009:02.

This picture highlights the global synchronicity of both the Great Recession and the Great Trade Collapse.10 Figure 7 plots the recovery following the Great Trade Collapse, using data from 2009 :Q2 through 2010:Ql. From this figure we see that most countries were recovering from the Great Recession during this period; only Spain, Greece, and Israel saw GDP de creasing over the period 2009:Q2-2010:Ql. India (omitted from the figure) was a strong outlier, with dramatic GDP growth of 21.8 percent over this period. The figure also demonstrates that the recovery of trade has been widespread and, for many countries, strong. Only Greece and Finland continued to experience declines in trade after 2009:Q2. To conclude, the highly synchronized nature of the global trade collapse that occurred in 2008-09 and the subsequent recovery suggests that analytical models of the Great Trade Collapse should be global in nature. 52 What caused the Great Trade Collapse and the subsequent recovery? What was behind the sharp decline in world trade that began in the second quarter of 2008? And what is behind the amazingly quick recovery in trade that we are experiencing today? The facts that we have gleaned from the data can help guide our analysis. First, we know that the Great Trade Collapse was extremely severe and steep by historical standards. Second, trade fell more dramatically than GDP around the world. Third, compared with previous episodes in which U.S. imports and exports fell, this trade collapse was much more highly synchronized around the world. In forming hypotheses to explain the causes of a phenomenon like the Great Trade Collapse, economists often begin with a simple supply-and-demand framework. If the quantity of imports falls during a recession, one likely culprit for this decrease is the decline in consumers’ incomes, which reduces consumer demand for all goods, 2Q/2011, Economic Perspectives FIGURE 7 The change in real trade vs. the change in real GDP after the Great Trade Collapse percentage change in real GDP Notes: For the legend explaining the country abbreviations, see figure 6.

In other words, as consumers tight ened their belts and bought fewer domestically produced goods, they also chose to buy fewer imported goods. However, we know that during the Great Trade Collapse, imports fell much more rapidly than income. Are there complicating factors behind a decline in consumer demand for imports? Possibly. As can be seen in figure 1 (p. 46), global trade began to take off in the mid-1990s. While there were many forces at work, a key element in this transition was the rise of global supply chains. Because companies now spread their production processes across multiple countries, the production of a specific good—for example, a car— involves multiple border crossings of a partially com pleted car that becomes more valuable with every step in the production process and every border crossing. Because customs agencies record the total value of every object that crosses the border and not the value added to the object during its most recent trip to a coun try, the value of trade recorded by national customs agencies has grown more rapidly than GDP as more and more companies and industries have spread their pro duction processes across many countries. It is difficult Federal Reserve Bank of Chicago to precisely measure the importance of trade in inter mediate goods (for example, an engine or brake for a car). That said, one OECD study11 estimates that the average annual growth rate of trade in intermediate goods among OECD members was 6.20 percent over the period 1995-2006, whereas the average annual growth rate in the trade of final consumption goods was only 5.87 percent over the same period. This finding suggests that the share of intermediate goods in total trade flows has been increasing as global supply chains have spread. In the Great Trade Collapse, we might have been observing the rapid unwinding of these global supply chains. Within a vertically integrated international economy,12 a simple fall in consumer demand for im ports would have been magnified through the global supply chains. For every car that is not produced and sold to a consumer, trade flows as measured by customs authorities fell by more than the final value of the car because that car, which would have crossed several borders during its production, did not cross any borders. So, in addition to falling consumer demand, this com plication generated by various multicountry production 53 processes may have played a significant role in pre cipitating and/or exacerbating the Great Trade Collapse. Another complicating feature of the demand side is that there are compositional differences between imports and national income, or GDP. Consider the United States’ imports and national income. The vast majority of imports into the United States are goods— for example, food, clothing, cars, and electronics— but some of these imports are services—for example, education, travel, and business consulting services. Our national income consists largely of services—for example, health care and education—with goods playing a much smaller role in our economy today than they have in the past. We might expect that consumption of some domestically produced services like health care is more recession-proof than the consumption of typi cally imported goods like televisions and refrigerators. How much of the Great Trade Collapse (and the sub sequent recovery) was due to a difference in the rela tive composition of tradable versus domestically produced goods and services? Returning to our simple framework, we note that the other likely cause of the recent trade collapse would be some type of disruption on the supply side—that is, some factor that affects the firms that are producing goods and shipping them to consumers and retail out lets. During the recent global recession, which started with a global financial crisis, the costs associated with exporting were carefully monitored for their potential impact on trade flows. Because the crisis was a finan cial one, governments and international organizations, such as the WTO and World Bank, tried to collect in formation on the costs of financing trade. Given the tight financial environment during the crisis, did firms face difficulty in obtaining different types of financing for their international shipments? In addition, were there problems associated with rising trade protection during the recent recession? It is widely known that the United States increased import tariffs during the Great Depression and that this likely worsened the severity of the depression during the 1930s. Did something similar happen this time around to cause or exacerbate the Great Trade Collapse? Demand-side explanations Is it surprising that trade collapsed during the recent global recession? As we discussed previously, the Great Trade Collapse was coincident with the largest decline in world GDP in decades. Should we not have expected that consumers, who buy less of everything during a recession, would also buy fewer imported goods? How can economists assess this problem on the demand side quantitatively? 54 To predict how exports or imports will change in the future, economists routinely estimate trade elasticities. Trade elasticities with respect to income measure how much a country’s imports or exports will change in response to changes in national income.13 For example, the import elasticity with respect to in come is a number that specifies how much imports will increase in response to a 1 percent increase in the total income of a country. Economic theory posits that this elasticity is positive. That is, an increase in a coun try’s income leads it to buy more from foreign countries. Moreover, an income elasticity of imports that is equal to one implies that imports increase proportionately with national income. For the past several decades, estimates of the im port elasticity with respect to income for the United States have ranged from 1.5 to slightly more than two.14 That is, in the United States, imports respond more than proportionately to changes in income. Precisely how much more depends on the exact value of the elasticity. In table 2, we list reported estimates of the import elasticity with respect to income for the United States by several different researchers. Using infor mation on the decline in U.S. GDP over the period 2008:Q2-2009:Q2, we can predict how large the U.S. decline in imports must have been in order to be in line with historical norms. Specifically, the actual cumulative change in U.S. GDP over this time period was -4.1 percent. In table 2, we use import elasticities with respect to income to predict the decline in imports during the Great Trade Collapse (2008:Q2-2009:Q2). Predictions for the change in U.S. imports range from a low of-6.2 percent, using a historical estimate from Houthakker and Magee (1969), to a high of-9.4 percent, using the more recent estimate from Chinn (2004) (the fourth column of table 2). But the cumulative change in imports over the period 2008:Q2-2009:Q2 was actually -18.3 percent. Estimates of the import elasticity with respect to income indicate that the decline in U.S. national income during the Great Trade Collapse can explain only about 35 percent to 50 percent of the decline in U.S. imports (see the last column of table 2). This simple analysis of demand-side factors tells us that imports fell about twice as much as we would have expected! How unusual is the Great Trade Collapse in this regard? That is, if we examine the other major contrac tions in U.S. imports since the 1970s, how do they com pare? Table 3 compares the Great Trade Collapse with five previous import contraction episodes in the United States. The first column lists the trough date of each of the six major contractions in U.S. imports reported earlier in figures 3 and 4 (pp. 47 and 49).

The third column displays the implied change in U.S. real imports over the four quarters before the trough date; we derive these values by multiplying the change in real GDP in the second column with the estimate of the import elasticity with respect to income (1.93) from Crane, Crowley, and Quayyum (2007). In the fourth column, we report the actual percent change in U.S. real imports over the four quarters before the trough date. Interestingly, in almost all cases the actu al changes in trade were substantially larger than the predicted changes in the third column. The last column lists the ratio of the predicted change in imports to the actual change in imports, which reveals how much of the decline in imports over the four quarters con sidered may be due to a decline in GDP over the same period. It appears that declining aggregate demand varies considerably in its importance as a cause for these trade declines. Thus, other factors, such as changing relative prices, trade barriers, or costs of Federal Reserve Bank of Chicago conducting international trade, must also contribute to these trade contractions. An import elasticity analysis of the trade recov ery from 2009:Q2 through 2010:Q2 leaves us with a quantitatively even larger puzzle. Over the period 2009:Q2-2010:Q2, U.S. GDP grew 3.0 percent, but U.S. imports of goods and services skyrocketed up 17.4 percent. Turning to table 4, we see that this dramatic increase in imports cannot be well explained simply by an improvement in aggregate demand. Table 4’s final column indicates that the increase in U.S. national income can explain only about one-quarter to 40 percent of the recovery following the Great Trade Collapse. As we stated before, during the Great Trade Collapse, a decline in U.S. aggregate income can ex plain only about half of the decline in imports. Similarly, when U.S. GDP began to recover after this collapse, U.S. imports surged well beyond the improvement predicted by the United States’ import elasticity with respect to income. So what other forces account for 55 TABLE 4 Predicted vs. actual change in U.S. imports, 2009:Q2-2010:Q2 Previous research Houthakker and Magee (1969) Hooper, Johnson, and Marquez (2000) Chinn (2004) Cardarelli and Rebucci (2007) Crane, Crowley, and Quayyum (2007) Sample period Import elasticity with respect to income Predicted percent change in imports Predicted change in imports/actual change in imports 1951-66 1961-94 1975-2003 1972-2006 1960-2006 1.51 1.79 2.29 2.03 1.93 4.5 5.4 6.9 6.1 5.8 0.26 0.31 0.40 0.35 0.33 Note: See the text for further details.

To address this question, we next examine some what detailed data on U.S. imports in order to identify compositional changes in imports that occurred over the period 2008-10. First, let us examine changes in U.S. imports of goods and services. Figure 8 plots real U.S. imports of goods versus services since the mid-1960s. A sig nificant decline and recovery occurred for imports of goods over the period 2008-10. Although the services industry plays a large role in the U.S. economy today, goods cross borders more often than services and were hit harder during the Great Trade Collapse. Over the period 2008:Q2-2009:Q2, U.S. imports of goods fell by 21.1 percent, while U.S. imports of services fell by only 3.5 percent. On the recovery side, from 2009:Q2 through 2010:Q3, U.S. imports of goods in creased 18.4 percent, while U.S. imports of services increased by only 6.2 percent. From these observations, we conclude that the Great Trade Collapse and the subsequent recovery were driven by changes in the trade of goods. Naturally, oil is suspected as one large factor be hind the Great Trade Collapse. Earlier we discussed the oil crisis of 1973 as a factor in a previous large trade contraction. How big a role did oil play in the most recent trade episode? Figure 9 plots real U.S. imports of petroleum and nonpetroleum goods in billions of chained 2005 dollars. We see that, although petro leum imports have grown over time, their importance as a share of all imports has declined. In 1974:Q2, oil represented 45.0 percent of U.S. goods imports, but by the time of the Great Trade Collapse in 2008:Q2, oil’s share of U.S. goods imports had fallen to 13.4 percent. Moreover, the peak-to-trough decline in oil imports of 13.4 percent during the trade contraction of 1974:Q2-1975:Q2 was substantially larger than the 56 7.0 percent decline that occurred during the Great Trade Collapse (2008:Q2-2009:Q2). Taken together, these facts indicate that oil imports played a relatively modest role in the most recent U.S. trade contraction. Having reviewed the role of trade in petroleum goods, we now focus on manufactured goods, which consist of durables and nondurables. In contrast to the modest decline in oil imports, U.S. imports of nonoil goods imports fell by 24.3 percent over the period 2008:Q2-2009:Q2. Figure 10 plots U.S. trade of non durable and durable goods. The decline in trade of durable goods—for example, automobiles, washing machines, and industrial machinery—was more severe than the decline in trade of nondurable goods—for example, clothing and food. During the Great Trade Collapse (2008:Q2-2009:Q2), imports in nondurable goods declined by 10.98 percent, while imports in durable goods declined by 28.6 percent; over the same period, U.S. exports in nondurable goods declined by 6.8 percent, while exports of durable goods declined by 24.3 percent. These findings suggest that an economic model that hopes to successfully quantify the contribu tions of various factors to the Great Trade Collapse should be characterized by a unique role for trade in durable goods. Supply-side explanations At the start of the 2008 economic crisis, policy makers observed that trade was falling dramatically and began to question the cause. Anything that reduces trade by raising the cost of selling a good in a foreign market is considered a supply-side cause. Two problems immediately raised concern. First, given that the world was in the midst of a financial crisis, policymakers ques tioned whether there was difficulty in obtaining trade finance. Second, policymakers questioned whether there was a rise in trade protection—that is, increases in import taxes or other government-sponsored barriers to trade. 2Q/2011, Economic Perspectives for goods that are bought and sold domestically because there is a high U.S. imports of goods and services, 1965-2010 er risk of nonpayment. If a seller gives merchandise to a domestic billions of chained 2005 U.S. dollars, seasonally adjusted purchaser and the purchaser does not pay, the seller can take the pur chaser to court. However, when the seller and purchaser are in different countries and the purchaser does not pay, it can be costly for the seller to get what is owed from the pur chaser. To mitigate this problem, banks can get involved in the pay ment process for international sales. Most trade—80-85 percent— occurs without any formal financing and/or insurance arrangements with banks.15 Still, banks are involved in such international trading activity. An “open account” payment is made Source: Authors’ calculations based on data from the U.S. Bureau of Economic Analysis, National Income and Product Accounts of the United States, from by the purchaser’s (importer’s) bank Haver Analytics. to the seller’s (exporter’s) bank after the purchaser receives the goods. However, banks are not extending loans or offering insurance under FIGURE 9 open account transactions.

Because there is no guarantee, verification, or in surance supplied by a third party, payment for merchandise on an open account is the cheapest way to process a transaction. The remaining 15-20 percent of world trade is financed through “letters of credit,” “documentary collections,” and similar products provided by banks or other third parties.16 These instruments, which Nonpetroleum I Petroleum come in many varieties, are payment methods in which a payment is re Source: Authors’ calculations based on data from the U.S. Bureau of Economic Analysis, National Income and Product Accounts of the United States, from leased from the buyer’s (importer’s) Haver Analytics. bank to the seller’s (exporter’s) bank after certain documents have been presented to the buyer’s bank that verify delivery of the merchandise.

According to the International Chamber of Commerce Banking Commission (2010), the cost of commercial letters of credit had increased during the recent financial crisis. The price of a letter of credit varies according to factors like the country of origin, the destination country, and the industrial sector. The International Chamber of Commerce survey evidence shows that prices of such letters increased by as much as 300-400 basis points over interbank lending rates during the height of the financial crisis in the fall of 2008.17 To assess whether financing difficulties with these payment instruments were a likely cause of the Great Trade Collapse, we need information on the quantities of financial instruments sold, their prices, and the vol ume of trade. Two prominent surveys18 were undertaken in early 2009 to try to fill in the gaps in policymakers’ knowledge about trade finance. While reports explaining both surveys inform our understanding of the trade finance situation during the crisis, both are thin on hard statistics. The reports indicate that in the uncertain envi ronment of the financial crisis, there was a relative in crease in demand for more secure methods of payment, such as letters of credit. However, because of the dif ficulty in obtaining data on the number of open account transactions involving merchandise trade,19 it is not possible to evaluate how the proportions of unsecured versus more secured methods of payment changed during the crisis. While the surveys show that exporters sought 58 out more secure payment methods as the crisis worsened, the total volume of letters of credit and documentary collections fell. Presumably, this occurred because trade fell. Lastly, according to the International Chamber of Commerce Banking Commission (2010), refusals of payments on minor technicalities increased through out the crisis and remained high in early 2010. These refusals were possible because even though letters of credit promise payment when documents are presented, a bank can refuse to make a payment if there are small discrepancies in the paperwork that is filed. To summarize, it appears that the cost of trading goods internationally likely increased during the Great Trade Collapse as exporters, worried about nonpayment, began to use more secure and expensive methods of payment. However, the precise magnitude of this cost increase is not known. What about other areas of trade financing? Letters of credit and documentary collections are not the only method of insuring payment by a foreign buyer. Export credit insurance can be purchased by exporting firms so that they are paid in the event of nonpayment by a foreign purchaser. As the recent global recession worsened, it appears that the use of export credit in surance increased from roughly 9 percent of world trade in 2008 to 11 percent of world trade in 2009.20 Claims paid to insured customers by members of the Berne Union, the leading international organization for export credit and investment insurance, doubled from 2008 2Q/2011, Economic Perspectives to 2009—from $1.1 billion to $2.4 billion. While this is a substantial increase, it covers only a small percent age of world merchandise trade (exports) in 2008, which the World Trade Organization (2009) estimated at $15.8 trillion. A third way in which the financial system can af fect international trade flows is through the provision of trade credit. Recall that transactions on an open account involve funds transfers between the buyer’s bank and the seller’s bank, but do not involve a loan from a bank. Rather, this type of sale is recorded as a positive “accounts receivable” for the exporter and, thus, is an informal loan from the exporter to the im porter. The provision of trade credit is more common in some industries than in others. For example, Chor and Manova (2010) calculate the amount of trade credit provided to buyers by suppliers in North America from 1996 through 2005.21 Industries such as transportation equipment manufacturing, which has a North American Industry Classification System (NAICS) code of 336, and fabricated metal product manufacturing (NAICS 332) receive relatively more trade credit than industries such as textile product mills (NAICS 314) or chemical manufacturing (NAICS 325). During the financial crisis, as the cost of borrowing money from a bank rose, it would have become more expensive for exporting firms to extend trade credit to their purchasers. While the rising cost of trade credit affects all firms that typically extend trade credit to their purchasers, there are reasons to believe that the problem could have been more severe for exporting firms. Domestic-marketoriented businesses as well as export-oriented businesses often obtain working capital loans from banks to cover the cost of purchasi ng inputs, paying workers, or renting equipment. They repay these loans after receiving pay ment from a buyer. For exported shipments, the time lag between the shipment of goods and payment receipt is 30-90 days longer than for domestic transactions.22 This means that working capital loans are especially important for export-oriented firms. To reiterate, an analysis of international trade pay ment methods is not going to provide much important information about whether the financial crisis had a unique impact on trade. While survey data suggest that costs of payment methods and export credit insurance increased, precise quantitative data are not available for economists to analyze. Economic research on the role of finance in the Great Trade Collapse will likely be more fruitful if it focuses on traditional credit instru ments—such as working capital loans and trade credit. Federal Reserve Bank of Chicago The role of trade protection in the Great Trade Collapse Before diving into a description of how trade policy changed during the Great Trade Collapse, it is useful to review the general trends in trade protection leading up to September 2008. A dramatic reduction in tariff rates and other nontariff barriers to trade began with the end of World War II; this reduction, combined with reductions in transportation and com munication costs, led to dramatic increases in global trade that outpaced the growth of global economic activity for the past few decades. Under the auspices of trade agreements like the World Trade Organization’s GATT,23 most countries around the world have, to a large degree, given up their unilateral authority to raise trade barriers. Members of the WTO agree to refrain from raising tariffs or imposing quotas above certain “bound” limits in exchange for the same cour tesy from other countries. However, the GATT gives countries permission to use some forms of trade protection under a variety of special agreements or exceptional clauses. For ex ample, a special tariff known as an antidumping duty can be imposed on specific products imported from a single country if a variety of economic criteria are met. However, this type of country-specific trade restriction has been found to be porous;24 if the United States restricts imports of a product from Japan by using an antidumping duty, another country like Germany will simply increase its exports of that same product to the United States, leading to, at most, a small reduction in total U.S. imports of that product. Economists know less about the effects of nontariff forms of trade pro tection. Government intervention into markets, regula tory changes, and changes in administrative procedures or health or environmental policies can be subjected to GATT disciplines if their trade-distorting effects are large. These less transparent policies can be difficult to identify, but organizations that run efforts like the Global Trade Alert database25 have begun the difficult task of compiling information about such policies and then analyzing their effects. Did we observe dramatic increases in trade barriers at the time of the Great Trade Collapse? No. Growing evidence suggests that, to date, trade protection has been more muted than expected and its trade-distorting effect has been mild at best.26 Figure 11 presents the recent state of U.S. trade protection activity under the antidumping duty. This is a special duty that the United States can use to restrict imports when a domestic industry is suffering injury— typically measured as reductions in employment and capacity utilization27 as well as reduced profitability— by reason of “dumped,” or unfairly priced, imports. 59 FIGURE 11 U.S. antidumping activity, 1979-2009 Antidumping investigations (left-hand scale) | Antidumping import restrictions (left-hand scale) ------ U.S. imports (right-hand scale) Source: Authors’ calculations based on data from Bown (2010). We plot of the frequency of newly initiated antidump ing investigations and new antidumping import restric tions in the United States from 1979 through 2009, as well as the level of U.S. imports in billions of chained 2005 U.S. dollars. In figure 11, the height of the light blue bar mea sures the number of new investigations that the U.S. government conducted into allegations of unfairly priced imports, while the height of the dark blue bar records how many of these investigations ultimately resulted in trade-reducing antidumping duties. The unit of ob servation is an investigation held into or trade restriction imposed against an individual country that exports to the United States.28 The tallest bar on the graph is in 1992; the light blue bar indicates that the U.S. govern ment conducted 94 investigations into allegations of dumping, and the dark blue bar indicates that 39 of these investigations found evidence of dumping and, con sequently, resulted in trade-restricting import duties. Superimposed over this graph of antidumping activity, the black line indicates the real volume of U.S. imports, in billions of chained 2005 U.S. dollars. It shows a strong and steady increase in U.S. imports that declined quite dramatically in 2008 and 2009. We can clearly see that for the United States, there were increases in both the number of antidumping investigations and the number of investigations that resulted in new antidumping duties in 2008 and 2009 60 relative to the pre-crisis years of 2005 and 2006. Moreover, these did occur as U.S. imports were falling. However, this rise in antidumping protection is consid erably smaller than the jumps in trade protection during earlier recessions. Previous spikes in antidumping activ ity coincided with the period of the strong U.S. dollar in the mid-1980s, the wake of the 1990-91 recession, and, most recently, the 2001 recession. Further, when we compare the number of antidumping investigations that resulted in dudes to the total volume of U.S. imports, we see that the fraction of U.S. imports subject to an tidumping duties appears to be quite low in 2008-09. Our principal observation here is that antidumping activi ty, which has been the most popular method of trade protection in the United States since 1980, did not increase significantly during the crisis. Figure 12 depicts the same information for Canada over the period 1985-2009. The key observation is that the pattern is quite similar to that in the United States. There was a small uptick in activity in 2008 over 2007, but the use of antidumping trade restrictions was quite modest by recent historical standards. Further, when we compare the recent use of antidumping duties to the total volume of Canadian trade, it appears to be trivial. How did trade protection evolve during the Great Recession? For most countries, there have not been substantial increases in explicit border measures like 2Q/2011, Economic Perspectives FIGURE 12 Canadian antidumping activity, 1985-2009 Antidumping investigations (left-hand scale) | Antidumping import restrictions (left-hand scale) ------ Canadian imports (right-hand scale) Source: Authors’ calculations based on data from Bown (2010). tariffs or quotas. If countries are changing their domestic regulations, administrative procedures, or health and safety standards in ways that discriminate against im ported goods (and thus have trade-restricting effects), these types of measures can be difficult for business people and policymakers to observe. Further, even when a potentially trade-distorting policy like the “Buy American” provision of the 2009 U.S. stimulus bill is well known, its trade impact can be difficult for economists to measure. While nontariff barriers could have a negative effect on trade, existing evidence from initiatives like the Global Trade Alert project suggests that the use of these policies has been restrained. The effect of major industrial policy initiatives on trade (for example, the General Motors bailout in the United States) has yet to be formally analyzed by researchers. Summarizing the hypotheses behind the Great Trade Collapse To summarize, we posited three leading hypotheses for what caused the collapse: 1) a decline in aggregate demand for all goods, including imports; 2) difficulties in obtaining trade finance; and 3) rising trade barriers. A quick analysis has suggested that the fall in aggregate demand can explain about half of the decline of imports into the United States. Our review of the changing com position of imports suggests that to fully understand Federal Reserve Bank of Chicago how declining demand affected trade during the Great Recession, a richer economic analysis that examines the structure of production and the composition of consump tion and trade is needed. With regard to trade finance, we explained why the lack of data on open account transactions makes it difficult to draw conclusions from the available data on payment methods for international trade. More fruitful avenues of research would examine how working capital loans and the provision of trade credit could have been mechanisms through which the recent global financial crisis reduced trade flows. Finally, with regard to trade protection, it seems that changes in traditional border barriers were not behind the trade collapse. In fact, governments’ willingness to refrain from trade restrictions allowed the trade re covery to progress swiftly. However, as high unemploy ment persists in much of the industrialized world, the calls for more trade protection and accusations of cur rency manipulation have been rising. Interestingly, in figure 11, the United States’ aggressive use of antidump ing duties associated with the 1990-91 recession peaked not during the recession itself, but in 1992, as high unemployment persisted with the United States’ “job less recovery.” Recent research on the Great Trade Collapse A large literature is emerging on the causes of the Great Trade Collapse. Here, we summarize and 61 review four important contributions. Each of these papers uses a different methodology and emphasizes different aspects of the trade collapse. From them, we can glean a composite picture of the collapse and be gin to quantify the contributions of underlying causes. This, in him, will guide us in assessing the policy actions undertaken by the G-20. Recall, as a starting point, that the simple trade elasticity analysis from table 2 (p. 55) indicates that the decline in U.S. aggregate de mand explains around 35-50 percent of the United States’ import collapse. What have other researchers learned about the causes of the Great Trade Collapse? Levchenko, Lewis, and Tesar (2010) Levchenko, Lewis, and Tesar (2010) ask how im portant was declining aggregate demand in explaining the collapse of trade in the United States. Their analy sis uses highly disaggregated data on trade flows and finds that the greatest declines occurred in sectors in which vertical production linkages29 are most important. In contrast, they find little to no evidence that trade financial difficulties were behind the United States’ trade collapse. Their paper proceeds in three distinct phases. First, they present data documenting the scale and industrial composition of the Great Trade Collapse in the United States. Second, they conduct a “trade wedge” analysis of macroeconomic data (which is discussed further in the next paragraph). Third, finding that a large portion of the United States’ trade collapse cannot be explained by declining aggregate demand, they examine other possible causes of the collapse. They undertake a crosssectional industry analysis of 1) vertical linkages among firms, 2) financial constraints, and 3) differences in the composition of trade and domestic demand to identify the most important causes of the Great Trade Collapse outside of falling aggregate demand. The “trade wedge” analysis is similar to the predic tions made using trade elasticities, which we presented earlier. The idea is to determine the “wedge,” or differ ence, between the actual decline in trade and the decline in trade that is due to changes in demand and changes in relative prices. The authors begin with a standard import demand function that relates changes in imports to changes in the price of domestic goods relative to the price of imported goods and to changes in consump tion and investment in the importing country. This function assumes that domestically produced and for eign goods are imperfect substitutes for one another and that the amount of imports increases as the price of domestically produced goods rises relative to the price of foreign goods. Further, imports increase as the total amount of domestic consumption and invest ment increase. Import demand is given by: 62 l) y vap ,>■ )+(D), where D = C +1; yf is the change over time in the logged level of imports; s is the elasticity of substitution between domestic and foreign goods; P is the change in the log of domestic prices; pf is the change in the log of import prices; and D is the change in the log of total consumption and investment in the importing country. Following previous research, the authors assume that s is equal to 1.5. They use this equation to predict the magnitude of the decline in U.S. imports over the period 2008:Q2-2009:Q2, given the actual quarterly data on changes in relative prices and changes in U.S. consumption and investment from this period. There are two important distinctions between this analysis and our analysis using trade elasticities. First, Levchenko, Lewis, and Tesar (2010) include a measure for relative prices. Inclusion of these price measures should increase the predictive power of their model relative to a trade elasticity analysis that only examines changes in demand. Second, they assume that the import elasticity with respect to income is one, roughly half the magnitude of the empirical esti mates reported in table 2 (p. 55). From their analysis, Levchenko, Lewis, and Tesar find that their standard import demand equation explains 60 percent of the decline in imports. The wedge is a 40 percent differ ence between the actual decline in imports during this period and the decline in imports predicted by their import demand equation. To demonstrate the uniqueness of the Great Trade Collapse as an economic phenomenon, Levchenko, Lewis, and Tesar (2010) calculate the size of the wedge for every year-over-year change30 since 1968. They find that the average wedge has been 2.9 percent since then. More recently, this import demand equation has improved in its ability to explain the behavior of imports. Since 1984, the average wedge has been 1.6 percent. What this means is that, while changes in relative prices and in domestic demand can explain almost all of the change in U.S. imports in a typical year, the wedge of 40 percent during the Great Trade Collapse was an aberration that, at first blush, is hard to explain. Faced with this puzzle, Levchenko, Lewis, and Tesar (2010) refine their analysis of the trade wedge to look as subsectors of the economy. They calculate the trade wedge for nonoil imports, durable goods, consumption goods, and investment/capital goods. The trade wedges for consumer goods (which represent around 20 percent of U.S. imports) and for investment/ capital goods (which also represent around 20 percent of U.S. imports) are small, -6.4 percent and -10 percent, 2Q/2011, Economic Perspectives respectively. For these sectors, the fall in demand and change in the relative prices explain almost all of the decline in imports. In contrast, the trade wedge for dura ble goods is a sizable -21 percent. While substantial, this is considerably smaller than the aggregate wedge of 40 percent. Thus, controlling for the composition of the trade flow can help explain some of the puzzle, and the authors conclude that the unusual behavior of trade in intermediate inputs and durable goods must be behind some of the unexplained portion of the Great Trade Collapse. Using industry-level data on the percent change in the flow of imports into the United States from June 2008 through June 2009, Levchenko, Lewis, and Tesar (2010) explore three hypotheses for what caused the Great Trade Collapse. First, they study the role of vertical linkages in production. Did goods that are used inten sively as intermediate inputs in production experience large percentage drops in exports and imports? Second, they ask how financial constraints affected trade. Spe cifically, they analyze whether sectors that extend or that intensively utilize trade credit experienced differ ential changes in their trade flows relative to sectors that do not. Finally, they investigate the role of trade’s industrial composition. Was the United States’ trade collapse unusually large because it was concentrated in goods purchased or sold by sectors that were espe cially hard hit during the Great Recession? To test these hypotheses, Levchenko, Lewis, and Tesar (2010) use data on approximately 450 sectors in the United States to estimate the following equation: 2) = a+ pCT/zIT?, + yW,. + e,.. In this equation, is the percent change in a trade flow from June 2008 to June 2009, CHAR is a measure of the industrial sector that will test one of the hypotheses (vertical linkages, trade credit, or sectorlevel industrial production), and X. is a vector of industry-specific control variables. To test the vertical linkages hypothesis, the authors create a measure that captures the intensity with which each good is used as an intermediate input in produc tion. They use the input-output matrix from the U.S. Bureau of Economic Analysis to calculate the average amount of a commodity input, z, used to produce a U.S. dollar’s worth of output in all downstream industries, j. The authors find that goods used intensively as in termediate inputs experienced larger percentage drops in imports and exports. Turning to the hypothesis that tight financial con ditions contributed to the Great Trade Collapse, the authors calculate two measures of trade credit intensity Federal Reserve Bank of Chicago in an industry. Using data from the Compustat North America database, they calculate the amount of credit extended to a firm by its suppliers as the median ratio of accounts payable to cost of goods sold. A second measure captures the amount of credit a firm extends to its customers—specifically, this is measured as the median ratio of accounts receivable to sales.31 For example, if a firm that typically extended trade credit to its buyers had difficulty obtaining working capital from banks during the financial crisis, that firm might cease to offer trade credit. Consequently, that might have led to a decline in U.S. exports. The authors find no evidence that trade flows fell more in sectors that typically either extend or receive trade credit. An examination of changes over time in the ratio of accounts payable to cost of goods sold and the ratio of accounts receivable to sales for firms in the Compustat database over the periods 20002009:Ql and 2004:Ql-2009:Ql, respectively, reveals that the contractions in trade credit during the financial crisis were relatively small. This supports the authors’ conclusion that difficulties in obtaining trade credit were not a major factor behind the Great Trade Collapse. This analysis does not disprove the idea that tight finan cial conditions could have contributed to the trade collapse. Rather, the analysis indicates that, after con trolling for other characteristics, sectors that regularly require upfront payments for inputs and sectors that regularly ship inputs to buyers in advance of payment experienced similar declines in trade. Finally, to test the hypothesis that the Great Trade Collapse occurred because of compositional differences between domestic output and trade, the authors exam ine the relationship between the cross-sectional con traction in output and the cross-sectional contraction in trade. For this analysis, an industry-specific measure of industrial production is used as the variable CHAR. in equation 2. Compositional differences do account for some of the Great Trade Collapse, according to Levchenko, Lewis, and Tesar (2010). In an examination of cross-sectional differences, imports and exports contracted more in sectors in which U.S. industrial production contracted more. Imports in durable goods sectors contracted 9.2 percentage points more than imports in nondurable goods sectors. In summary, Levchenko, Lewis, and Tesar (2010) first quantify that approximately 60 percent of the Great Trade Collapse is due to the contraction in domestic demand associated with the Great Recession and to changes in the relative price of imports to domestic goods. They then analyze cross-sectional changes in trade flows and conclude vertical linkages and composi tional differences between domestic production and 63 trade were important contributing factors to the Great Trade Collapse. This partial equilibrium cross-sectional approach does not lend itself to quantification of the underlying causes of the collapse of aggregate U.S. imports. However, from this empirical analysis, we can see that a good economic model of the Great Trade Collapse must include a distinction between nondurable and durable goods and a careful modeling of inputs and final goods. Eaton et al. (2011) Eaton et al. (2011) take a different approach to studying the Great Trade Collapse. They complete an empirical analysis on the Great Trade Collapse as a global phenomenon. This paper begins with the observation that the ratio of global trade to GDP declined by about 30 percent from 2008:Q2 through 2009:Q2. In con trast to Levchenko, Lewis, and Tesar (2010), who are agnostic about the underlying structure of the economy, Eaton et al. (2011) build a structural model of the global economy. They then use their model to reproduce the Great Trade Collapse from possible causes. This methodological approach has the additional benefit of allowing the authors to quantify the contributions of different factors to the Great Trade Collapse. Eaton et al. (2011) begin with a standard gravity model of trade among 23 countries. This workhorse model of the international trade literature relates the volume of trade between any two countries to the dis tance between them.32 To the gravity model, they add three production sectors—durable manufacturing, nondurable manufacturing, and nonmanufacturing— and a detailed input-output structure for each country. The possible causes of the trade collapse are included in the model as “shocks,” variables subject to exoge nous changes in their value that can then propagate throughout the model economy. In the Eaton et al. (2011) model, there are four distinct types of shocks: demand shocks, trade deficit shocks, productivity shocks, and trade friction shocks. In this paper, a demand shock, which is countryspecific, is a change in the share of final demand that is spent on goods from each sector—durables, nondu rables, or nonmanufacturing. In this setup, changes in final investment activity or changes in durable inven tories are captured by demand shocks. The equilibrium in this model is a function of each country’s aggregate trade deficit and its nonmanufacturing deficit. Because the model is static, these trade deficits are treated as exogenous shocks. Productivity shocks—which measure how much of an output change cannot be explained by changes in inputs of capital, labor, and materials— and trade friction shocks—which capture all kinds of changes in barriers to trade—are estimated from data 64 on sectoral producer price indexes and bilateral trade shares at the sectoral level. The trade friction shocks capture anything that changes individuals’ home bias33 in consumption, such as 1) changes in shipping costs, 2) changes in tariffs, 3) changes in nontariff barriers, and 4) difficulties in obtaining trade finance. Further, any reduction in imported inventories associated with a large fixed cost of importing—as in Alessandria, Kaboski, and Midrigan (2010) discussed later—would also be captured by the trade friction shock. The authors find that a decline in the demand for durable manufactured goods explains 65 percent of the decline in the global trade-to-GDP ratio during this period. The decline in total demand for durable and nondurable manufactured goods explains about 80 percent of the fall in the global trade-to-GDP ratio. Finally, they find that increases in trade frictions (difficulties with trade finance and rising trade protec tion) reduced trade for China and Japan but had little or no impact on other countries. How is it that Eaton et al. (2011) find that 80 percent of the trade collapse is due to the decline in demand, while a simple im port demand analysis implies that declining demand can explain only about half of the collapse? A key difference between Eaton et al.’s (2011) analysis and the import demand analysis in this article or that con ducted by Levchenko, Lewis, and Tesar (2010) is that Eaton et al. (2011) develop a richer model that incor porates important features of the vertical structure of trade and production. In their richer framework, a fi nal demand shock in one country can fully propagate itself through the demand for traded inputs into pro duction of both durables and nondurables. Chor and Manova (2010) Both Levchenko, Lewis, and Tesar (2010) and Eaton et al. (2011) examined demand and supply fac tors as possible causes of the Great Trade Collapse, and found that weak demand was quantitatively the most important factor. A study by Chor and Manova (2010) focuses on a supply-side cause by looking at the availability of trade financing during the financial crisis. When global credit markets froze, the market for trade credit tightened, but not nearly as severely as other markets. The paper concludes that tighter trade financing conditions contributed to the collapse, but this contribution was modest. Chor and Manova (2010) ask how tight credit affected trade volumes. Their empirical analysis of the Great Trade Collapse focuses on whether countries with higher borrowing costs exported less to the United States during the crisis. Their paper exploits cross country and intertemporal variation in the interbank rate, the interest rate at which banks lend to one another, 2Q/2011, Economic Perspectives to identify if tight financial conditions differentially affected different countries’ monthly exports to the United States. While the global nature of the financial crisis meant that interest rates in different countries followed a similar path throughout the crisis, Chor and Manova use high-frequency data to capture small differences in borrowing costs across countries and over time. They hypothesize that countries with lower interest rates should have experienced smaller declines in the volume of their exports to the United States. Consider Chor and Manova’s (2010) simplest model—the relationship between U.S. imports from different countries, designated i, in different three-digit NAICS industrial sectors, designated k, at a monthly frequency, t, as a function of the interbank lending rate in country i over time. 3) inYikt-7lIBRATEit+y2DcnsisxIBRATEit + ^ + 8,, where F,; is U.S. imports from country i in sector k in month t, IBRATE.the interbank rate in country i and month t, the variable D is a 0-1 indicator variable equal to 1 in every month from September 2008 through August 2009, the variable D,: is a full set of sectormonth fixed effects, and s.fe is an error term. The co efficient y captures the effect of a change in the inter bank rate on a country’s exports to the United States, whereas the coefficient y2 captures the additional effect of the interbank rate on a country’s exports to the United States during the financial crisis. This formulation allows for the possibility that the interbank rate might have affected trade flows during the crisis in an unusual way. From this simple model, Chor and Manova (2010) find (in a specification that omits the crisis dummy) that a 1 percent increase in the cost of bank financing is associated with a 16 percent fall in that country’s exports to the United States. However, after control ling for industrial production in the exporting country, the effect of the interbank rate on exports is generally not significant. Thus, while there is some evidence that tighter financial conditions, measured as a higher economy-wide borrowing rate, was associated with a lower level of exports to the United States, it is not clear whether this decline in exports was caused by tighter borrowing conditions or whether the tighter borrowing conditions were simply correlated with other adverse changes occurring in these exporting economies during the crisis. Chor and Manova (2010) then turn to a more re fined question of whether sectors that are more reliant on financing exported less to the United States during the crisis. They exploit cross-sector dependence on different types of external financing, together with Federal Reserve Bank of Chicago intertemporal changes in the interbank rate, to learn how the financial crisis affected trade flows of different types of goods. They estimate the following empirical model on monthly imports into the United States: 4)7 In Y.,ikt = D.it + D,kt + D,ik + G,IBRATE x FIN,k r1 it + ff D x IBRATE x FIN, + e , . Again, i indexes a foreign country, k indexes a threedigit NAICS sector, and t indexes time in months. The key innovation in this expression, relative to equation 3, is the inclusion of the variable, FINk, one of three time-invariant measures of financial vulnerability. All measures of financial vulnerability are constructed from all publicly traded firms in the Compustat North America database.34 The authors first calculate the average value of the financial vulnerability variable for each firm over the period 1996-2005. They then use the median value of this average within a sector as the sector’s time-invariant measure, FIN,. The first measure of financial vulnerability that Chor and Manova (2010) analyze is the external finan cial dependence of a sector. External finance depen dence is the fraction of total capital expenditures not financed by internal cash flows from operations. Thus, we might expect that sectors with high levels of this variable would experience greater declines in trade flows. The next measure they explore is asset tangi bility—that is, the share of net plant, property, and equipment in total book value. Because a firm with lots of tangible assets can easily provide collateral for a loan, one might expect that it is easier for these firms to ob tain loans on advantageous terms. Finally, in a setup similar to that of Levchenko, Lewis, and Tesar (2010), Chor and Manova (2010) examine how access to buyersupplied trade credit affects cross-country exports at the sectoral level. In their analysis, the change in ac counts payable relative to the change in total assets measures a sector’s access to buyer-supplied trade credit. Chor and Manova (2010) find evidence that sup ports the idea that financial difficulties contributed to the Great Trade Collapse in the United States, but the empirical support for this conclusion is not robust across all specifications of their models. Overall, they find that 1) sectors that are more reliant on external finance had a slightly weaker export performance, 2) sectors with relatively more tangible assets exported relatively more, and 3) sectors that routinely receive trade credit from buyers experienced smaller declines in their exports to the United States. More specifically, when the fraction of total capital not financed by internal cash is used as the measure 65 of financial vulnerability in equation 4, the coefficient [> is identified from the variation in financial depen dence across industries within a given country-month, the variation in the cost of credit across exporting countries in a given sector-month, and the variation in the cost of credit over time within a given country’s sector. The coefficient [V, relies on the same sources of variation in the data for the months of the world wide financial crisis. Empirically, the authors found that P2 was negative and precisely estimated in almost all specifications, but that estimates of (i were not statistically different from zero. This suggests that dur ing the financial crisis, high interest rates tended to depress U.S. imports in financially vulnerable sectors. With regard to the specifications that used the level of tangible assets as the financial variable, recall that a sector with more tangible assets should be less sen sitive to worsening credit conditions because any loan it requests can be collateralized by its tangible assets. Thus, the authors hypothesize that both p and P2 should be positive. In fact, they find that |> is positive in all specifications, but statistically significant in only the regression that omits the crisis dummy interaction term. Further, P2 is positive in almost all specifications, indicating that this effect was stronger during the finan cial crisis. Thus, exporting firms that faced high borrow ing costs performed better if they were in sectors with relatively high levels of tangible assets. Lastly, Chor and Manova (2010) consider the role of trade credit in explaining the Great Trade Collapse. These results are most directly comparable to those of Levchenko, Lewis, and Tesar (2010), but the two papers use different measures of trade credit.35 As stated pre viously, one measure of financial vulnerability used by Chor and Manova (2010), buyer-supplied trade credit, is the change in accounts payable divided by the change in total assets. This ratio measures how much credit American purchasers in these sectors extend to foreign exporters. The positive coefficient estimate on p indi cates that countries with high interbank rates exported relatively more in sectors in which American buyers typically extend high levels of trade credit. The positive coefficient estimate on P2 indicates that this effect be came more pronounced during the crisis. This suggests that financial constraints did exacerbate the collapse of trade. But how do we reconcile the different findings on trade credit in Chor and Manova (2010) and Levchenko, Lewis, and Tesar (2010)? The two papers exploit dif ferent sources of variation in trade flows. Levchenko, Lewis, and Tesar (2010) look at differences in the provision of trade credit across sectors within the United States. Their analysis looks for differences in 66 import growth across sectors that are systematically linked to differences in trade credit, but does not find significant changes in imports that coincide with the trade credit measure. In contrast, Chor and Manova (2010) exploit cross-country variation in the cost of financing within a sector. They compare sectors A and B in countries 1 and 2, all of which export to the United States. Their analysis finds that if sector A receives a relatively high level of trade credit and the interbank rate is relatively higher in country 1 than in country 2, then the relative exports of sector A to sector B in country 1 will be larger than the relative exports of sector A to sector B in country 2. This more refined analysis is able to capture the subtle effects of financial difficulties that varied across countries and over time. Finally, Chor and Manova (2010) conduct counterfactual simulations with their model to try to quan tify how severe the Great Trade Collapse would have been if central banks and national governments had not intervened to lower borrowing costs around the world. They estimate that U.S. imports in the most financially vulnerable sectors would have been substan tially lower after September 2008 without the aggres sive reduction in interbank lending rates that occurred. Alessandria, Kaboski, and Midrigan (2010) A final important contribution exploring the causes for the Great Trade Collapse is Alessandria, Kaboski, and Midrigan (2010). They develop a quantitative dynamic model of trade and production to analyze the Great Trade Collapse in the United States. Their approach is unique in that it focuses on a new channel of trade dynamics—namely, the behavior of inventory investment over the business cycle. Consider the following stylized example that Alessandria, Kaboski, and Midrigan (2010) present. Suppose a firm would ideally hold three units of a good in inventory for each unit that it sells. In other words, the firm’s ideal inventory to sales ratio is three. If a recession causes the firm’s sales to fall, its inventory-to-sales ratio will increase above its ideal level. This would lead the firm to purchase fewer goods from its supplier to hold in inventory in the next period. If the supplier is a foreign firm and the domestic firm’s inventories are all imported goods, then a decline in the domestic firm’s final sales in one period will lead to a more than proportionate reduction in its purchase of imported inventory in the following period. Alessandria, Kaboski, and Midrigan (2010) formally assess the role of inventory investment during the Great Trade Collapse by integrating a partial equilibrium model of trade and inventory adjustment into a twocountry general equilibrium model of trade. The key 2Q/2011, Economic Perspectives feature of this model is that if transaction frictions are higher for imported inventories than domestic inven tories (that is, those purchased from domestic partners) so that domestic producers with imported inventories target a higher inventories-to-sales ratio, then any shock that causes final sales to fall will have a larger effect on imported inventories than on domestic inventories. Alessandria, Kaboski, and Midrigan calibrate their model to U.S. data and find that their model with inventory decumulation generates dynamic patterns for production, trade, and inventories that are quantitatively similar to those observed during the Great Trade Collapse. A particularly good feature of this model is that the dramatic collapse in imports is followed by a sharp recovery, similar to what we have observed for the recovery following the Great Trade Collapse. Conclusion The collapse in international trade between the second quarter of 2008 and the second quarter of 2009 is one of the most dramatic features of the Great Recession. This collapse in world trade of over 17 per cent from peak to trough was massive, not only in terms of its U.S. dollar value but also by historical standards. The G-20 leaders responded to this dramatic decline in trade with three distinct policy initiatives—1) fiscal stimulus to support aggregate demand, 2) trade finance initiatives, and 3) promises to refrain from new trade barriers. To assess the likely impact of these policies, we explored in this article three main possible causes of the Great Trade Collapse—namely, 1) declining demand, 2) financing difficulties, and 3) rising trade barriers. Economists have proposed several hypotheses to explain the Great Trade Collapse; in addition to the three already mentioned, some have posited the fol lowing as possible contributing factors: differences in the composition of trade and domestic output and the behavior of imported inventories. Federal Reserve Bank of Chicago Research suggests that declining demand can explain between 35 percent and 80 percent of the de cline in trade over the period 2008:Q2-2009:Q2. The analysis we perform in this article estimates that de clining aggregate demand explains 35-50 percent of the Great Trade Collapse. With regard to the recov ery, our analysis finds a quantitatively larger puzzle; rising aggregate demand explains only 25-40 percent of the recovery in imports. The decline in aggregate income is able to explain a larger fraction of the decline in trade in a more sophisticated model that accounts for differences between durable, nondurable, and non manufacturing output, as well as the vertical structure of production. The conclusion that declining demand was the major cause suggests that of all the policy ac tions, fiscal stimulus likely had the largest impact on the trade recovery. There is some evidence that financing difficulties contributed to the Great Trade Collapse, but the pre cise quantitative significance of financial factors is difficult to assess. The G-20’s announcement in the second quarter of 2009 that it would ensure the avail ability of $250 billion for trade finance coincided with the nadir of the Great Trade Collapse. However, we cannot conclude from the coincidence in timing that government aid with trade finance caused the trade recovery. It likely had a positive impact that was dwarfed by the positive impact of the economic recovery. There is almost no evidence that trade policy barriers rose during the period of trade collapse and recovery. Historical experience with trade protection ism teaches us that the trade collapse would almost certainly have been worse if policymakers had responded to the crisis by erecting new barriers to trade. Further, it seems that the dramatic demand-driven trade recovery was only possible because there were no trade barriers in place to impede it. 67 NOTES ’Our calculation is based on data from the Organisation for Economic Co-operation and Development’s Main Economic Indicators, in which world trade in goods and services is defined as the sum of world exports in goods and services and world imports in goods and services divided by two; data are from Haver Analytics. 2For a complete list of G-20 nations, see www.g20.org/about_ what_is_g20.aspx. from SWIFT (Society for Worldwide Interbank Financial Telecommunication)—a private provider of electronic financial messaging services.

That said, this legally defined unit of observation has been used consistently since 1980 and is a useful measure for looking at long term trends. "Measures of an industry’s downstream vertical linkages capture the intensity with which the output of an industry is used as an intermediate input by other sectors. Measures of an industry’s upstream vertical linkages capture the intensity with which that industry uses intermediate inputs. (See Levchenko, Lewis, and Tesar, 2010, p. 14.) Deardorffs ’ Glossary ofInternational Economics defines an intermediate input as “an input to production that has itself been produced and that, unlike capital, is used up in produc tion” (Deardorff, 2010). 30For example, they calculate the change between the first quarter of year t and the first quarter of year t - 1, the second quarter of year t and the second quarter of year t - 1, and so on. 3’Both measures in Levchenko, Lewis, and Tesar (2010) first take the median value of the variable for each firm in the sample between 2000 and 2008. Next, they take the median of the value across all firms to use as the industry’s measure of trade credit intensity. 2Q/2011, Economic Perspectives 32The term gravity model comes from the observation that trade volumes tend to increase as the distance between any two countries decreases, similar to the force of gravity between two objects in creasing as the distance between the objects decreases. In addition, this term is also based on the observation that the trade volume for an economy grows larger as the size of an economy increases, analogous to the gravitational pull of an object becoming larger as its mass increases. 34Note that Chor and Manova (2010) are assuming that the financial vulnerability in foreign industrial sectors is identical to that of the same sectors in North America. 35The measures used in Levchenko, Lewis, and Tesar (2010) are described in detail on p. 63 and in note 31. 33From Deardorffs ’ Glossary ofInternational Economics'.

Sumit Agarwal, Souphala Chomsisengphet, and John C. Driscoll Introduction and summary Companies borrow from investors for a variety of reasons. For example, current sales revenue may not be enough to pay suppliers or employees; companies may wish to make long-term investments by buying new equipment or constructing new buildings; or they may want to have access to credit to deal with unforeseen circumstances. Large companies have a wide menu of choices for bor rowing funds, including issuing new stock or bonds. Small companies tend to have a smaller set of options. Because such companies may also be younger than large companies and, thus, have a shorter track record, or be cause they may be more reliant on the performance of a small number of key employees, these firms will face more difficulty in conveying their value to the broad class of investors who participate in the bond or stock markets. Small firms are thus often privately held (that is, their stocks are not traded on public exchanges). These privatefirms likely rely on bank loans for much of their borrowing, as banks may be better able to spend the resources to investigate the firms’ prospects.1 Such small, bank-dependent firms are vulnerable to problems in the banking system. Indeed, a number of researchers argue that monetary policy and other economic shocks that impact the supply of credit flow through banks to bank-dependent firms.2 Although banks make many traditional spot loans, in which the whole amount of the loan is provided to the firm, much business lending takes the form of a credit line, also known as a Zon« under commitment. In a loan under commitment, the bank agrees to provide funds to the firm as needed up to a pre-specified limit, at mutu ally agreed-upon terms and over a fixed period. As of the end of the second quarter of 2010, commercial banks held $1.1 trillion in commercial and industrial loans on their books, but had about $2 trillion in unused com mitments (that is, the portion of the credit line not yet used) on business credit lines.3 Federal Reserve Bank of Chicago The market for loans under commitment is impor tant because it represents a large portion of business lending and the majority of small business finance. In addition, loans under commitment may be one channel through which monetary policy and credit shocks are transmitted to the broader economy. However, a lack of available data has made it difficult to study loans un der commitment or small business lending more broadly defined. Standard government data sources on banking, such as the Reports of Condition and Income, also known as the Call Reports (produced by the Federal Financial Institutions Examination Council, or FFIEC), or the Federal Reserve System’s weekly bank credit data (H.8 statistical release), do not break out business lending by the size of the borrowing firm. Publicly traded firms are required to issue quarterly reports on their balance sheet, including details of their financing, but private firms do not have such requirements. In this article, we use a panel data set from a large bank to examine the behavior of loans under commitment made to privately held firms. The data set contains all of the characteristics of the credit lines and all of the financial information about the firms that is available to the bank. As with any lending market, the interest rate on the loan under commitment, the collateral and other re quirements for the credit line, and the amount of the Sumit Agarwal is a senior economist in the Economic Research Department at the Federal Reserve Bank of Chicago.

In the absence of further identifying assumptions, we will not know whether these prices and quantities change over time or differ across firms because of changes in factors driv ing supply or factors affecting demand for these loans. However, our data set provides us with information on both the amounts of credit that firms requested and the amounts granted. Restricting our analysis to those cases in which the amount requested is equal to the amount granted helps us to ensure that observed differ ences in prices and quantities across firms reflect differences in firms’ demand for credit rather than differences in banks’ willingness to supply credit. Still, no attempt to solve the problem of separating supply and demand is perfect, and some of our results on the determinants of credit demand may partly capture factors that affect credit supply instead. Economists have hypothesized a number of reasons why companies might choose to borrow via credit lines rather than spot loans, including the need to hedge against the possibility of a sudden deterioration in their own creditworthiness and a desire for flexibility to be able to quickly take up new investment opportunities. We look at some of the factors that affect these and other reasons underlying the demand for lines under commit ment. We find that increases in fees paid on the com mitment and the interest rate charged to the firm lead to large reductions in the size of lines obtained—in other words, the demand curve does indeed slope down ward with the cost of the loan. Increases in fees for overcharging the lines raise line demand (as firms pre sumably try to avoid such overcharges by borrowing more at the outset). Increases in mean profit growth— a proxy for future investment opportunities—lead to very large increases in credit lines, while increases in the volatility of profit growth or in cash flow (a source of internal funds) cause, respectively, large and mod erate decreases in the size of lines; these results sug gest that access to funds for flexibility is an important motive, as described in the model developed by Martin and Santomero (1997). We find weak evidence against models in which loans under commitment help firms to hedge against the possibility that their own credit ratings may decline; we estimate that the quantity of credit demanded is negatively related to measures of firm risk. If firms do use credit lines to enhance their flexibility, many of the same factors that affect their demand for the size of the line will also affect their usage of the line. Firms will not want to use all of their lines, as that would leave them at risk of not being able to fund new opportunities. We test this idea by examining whether 72 line utilization responds to the same variables that in fluence line demand. With the exception of upfront fees, all variables affect line utilization in the same way as they do line size. In the next section, we summarize the academic literature on business credit lines. We then discuss our data set and the setup for our estimation. Finally, we present our results and discuss their implications. The economics of loan commitments When a firm takes out a loan under commitment (or credit line), the bank commits to providing up to some amount of credit to the firm over a specified period. The firm is not obligated to take out the full amount of the credit line at once and, indeed, usually does not do so even over the entire duration of the contract. The bank charges the firm for setting up the line (known as the commitment fee); it may also charge other fees or penalties if the firm exceeds the line limit or other wise breaks the contract. Both spot loans and credit lines usually require the firm to post collateral. Firms face some trade-offs in choosing between spot loans and credit lines. For example, the existence of the commitment fee, holding everything else equal, makes a credit line more costly to a firm than a spot loan. The economics and finance literature provides several competing views on the relative merits of spot loans and loans under commitment and how firms choose between them. According to one view, loan commitments allow firms to hedge against any deterioration in their own creditworthiness over the period of the loan.4 If a firm suffers such a deterioration, it may have trouble getting a new spot loan. Having a partly unused line of credit would provide the firm with needed funds in this case. This option would only be available if the bank was not able to use the deterioration as an excuse to cut the size of the firm’s credit line. A second body of work argues that loan commit ments help private firms hedge against decreases in the aggregate supply of credit, or credit crunches.5 Firms may be concerned that a decrease in the supply of credit by the banking industry—such as what occurred in the aftermath of the savings and loan crisis of the early 1990s—will leave them less able to borrow. Of course, a banking industry crisis may coincide with a period of declining creditworthiness. Both of these phenomena may have been at work during the recent financial crisis. In the third quarter of 2008, commer cial bank lending to businesses expanded rapidly while the fraction of loan commitments unused dropped, sug gesting that businesses were drawing down their credit lines during a time when activity in other corporate 2Q/2011, Economic Perspectives credit markets, such as that for commercial paper, was rapidly diminishing.6 A third view contends that loan commitments are attractive to both firms and banks because they help solve information problems that make it difficult for firms to borrow on the spot markets for loans or commercial paper.7 According to this view, some firms may be par ticularly difficult to value, perhaps because they have assets that have illiquid markets or because the firms are small and rely heavily on the work of a few key in dividuals. Such firms will have difficulty borrowing in the bond and commercial paper markets since it will be difficult to convey the riskiness of the securities to the broad class of investors who participate in such mar kets. Banks are better able to investigate the quality of the firm and monitor its behavior. Credit lines also provide more protection to the bank than spot loans because the bank may have the option of cutting the unused portion of the line if circumstances change. A final view argues that the relative speed and flexi bility offered by credit lines enables firms to take advan tage of investment opportunities they might miss if they had to take the time to obtain approval for spot-market loans (see Martin and Santomero, 1997). This flexibility makes the extra costs (in the form of fees and higher interest rates) of loans under commitment worthwhile to the firm. These reasons are not mutually exclusive; it is likely that all of them contribute, to some degree, to devel opments in the market for credit lines. The empirical evidence on these explanations is a bit mixed, in part because of the data availability difficulties alluded to in the introduction. Also, with a variety of explanations, it is difficult to estimate the contribution of any indi vidual one (and many studies have focused on evalu ating one of many possible explanations). Several authors have found that macroeconomic developments in the market for bank loans appear to affect the quantity and price of loans, providing support for the second view: Borrowers take out credit lines because they are con cerned about decreases in the aggregate supply of credit.8 Shockley and Thakor (1997) find some evidence for the third view: Borrowers that appear to be harder to value (because they are less well known or have assets that are difficult to value) tend to use credit lines rather than other nonbank forms of finance, such as commercial paper. Ham and Melnik (1987) look at the determinants of usage of credit lines (that is, conditional on having obtained a loan under commitment, what fraction of that loan is used). Using a sample of 90 nonfinancial corporations, the authors find that credit line usage is positively related to total sales, borrowed reserves, and Federal Reserve Bank of Chicago whether collateral is used to secure the loan; and it is negatively related to interest rate costs (specifically, risk premiums and commitment fees). Much of this empirical work has attempted to identify what determines banks’ willingness to supply credit. The papers that have focused on the demand for credit have used data on larger, publicly traded corpora tions. As we discuss in the next section, our data allow us to study smaller firms that are not publicly traded and, we argue, to analyze demand for credit by these firms. Data and empirical strategy Data Our unique data set comes from a large commercial bank that issued lines of credit to both publicly traded and private firms. For this article, we restrict our sam ple to private firms with fewer than 500 employees. Our data set has independently audited quarterly balance sheet data on the firms from the second quarter of 1998 through the fourth quarter of 2002 and monthly loan performance information from the first quarter of 2001 through the fourth quarter of 2002. Tables 1 and 2 provide some summary statistics for the firms in our sample. The top panel of table 1 gives the distribution of firms across industries and the bot tom panel gives the distribution across geographical locations. The firms are distributed across seven broadly defined classes of industry, ranging from manufactur ing to retail and wholesale trade to services, and are located in five northeastern states. Table 2 provides means and standard deviations (a measure of dispersion) on other firm characteristics and balance sheet information. The mean age of the firms is about ten years. The firms on average hold just above $2 million in total assets and have about $630,000 in working capital. The firms in our sample have relatively robust annual growth rates of profits and sales, of about 22 percent and 25 percent, respectively. On a scale of 1 to 8, with 1 being the least risky, the average firm receives a rating of about 5. The remain ing entries in the table are characteristics of the firms’ credit lines. The firms incur an average of about $1,800 in fees, paid upfront, to take out the credit line. They pay an average of 8.41 percent plus a risk premium of 39 basis points on any amount drawn from the credit line and a penalty rate of about 2 percent on any amount drawn above the stated line amount. To obtain credit lines, 95 percent of the firms in our sample used col lateral to secure the line commitment, with about 19 percent using deposits at the bank and 76 percent using business assets as collateral. The average line com mitment for our sample firms is a little under $ 1 mil lion. Over the two-year period covered by our sample, 73 firms on average draw down a little over half of their credit line. Empirical strategy Although we can use our data to look at correlations between the quantity and price of credit lines and oth er firm and industry characteristics, in the absence of further assumptions we can’t be sure whether those relationships are driven by changes in the supply of loans or changes in the demand for such loans. However, one piece of information we observe on the loans helps us identify the difference between supply and demand: We see both the amount of the loan asked for by the firm and the amount granted by the bank. We argue that if we restrict our analysis to cases where the amounts asked for and granted are the same, the resulting differences in prices and quantities across firms will reflect differences in demand for commit ment lines rather than supply. You can think of this as firms submitting an application for a given line com mitment where the price is posted by the bank. To see this, consider two firms that happened to demand the same amount of credit, but differed in some character istic that led the bank to be less willing to lend to one firm than to the other. Then we should observe that for one firm, the amount supplied is equal to the amount demanded; but for the other, the amount supplied would be less than the amount initially demanded. Thus, the differences in the amount (and the price) transacted would be attributable in that case to differences in fac tors affecting loan supply. In contrast, by looking at cases where the amount demanded is equal to the amount supplied, we can be more confident that any differences in quantities (and prices) across firms are attributable to differences in the demand for credit across those firms. Making this restriction reduces our sample from the original data set of 1,147 firms to 637 firms. Since no identification scheme is perfect, we acknowledge that some of the factors we identify here as contributing to credit demand may also be contributing to credit supply. By allowing us to estimate the determinants of firms’ demand for loans under commitment, this ap proach also permits us to determine the degree to which some of the hypotheses about firms’ demand for credit lines are applicable. To some extent, we can evaluate the first and third hypotheses—that firms use credit lines to hedge against deteriorations in their own creditworthiness or to solve problems with informational asymmetries inherent to other forms of borrowing— by incorporating risk measures of the firm. It is a bit difficult in our sample to determine the role of the sec ond hypothesis—insurance against aggregate declines in consumer credit.

We can partially test the fourth hypothesis—that firms take out credit lines for their flexibility—by including proxies for the firm’s likely need for funds. 2Q/2011, Economic Perspectives Our main specification is: (?■ = 30 + P'Przce. + ^NetFundNeeds, + \VRisk, + ^Collaterals + P54?e,. + (^Industry, + |:i7 Statet Q. is the size of the credit line normalized by firm assets; we do this normalization because credit line demand may be very different for different sizes of firm. Price, is a set of contract pricing components, in cluding fees charged for setting up the line, fees for overdrawing, the interest rate charged on funds drawn, and the risk premium spread. NetFundNeeds.l consists of measures of the mean and standard deviation of the firm’s net need for exter nal funds, cash flow, and working capital. Martin and Santomero’s (1997) model suggests that these param eters are two important determinants of the size of credit lines. Since net need for funding is not directly observ able, we need to proxy for its mean and standard devi ation. The need for external funds will be greater the more investment opportunities are available. If firms are persistently able to find good investment opportu nities, they will be persistently profitable. Thus, we use the mean and standard deviation of net profits over our sample as our proxy for the mean and standard devia tion of net credit needs. We include cash flow and work ing capital because externally borrowed funds are needed less when more internal funds are available. Risk. is the bank’s risk rating for firm i. Collateral, consists of two dummy variables— one for the use of deposits at the bank and one for the use of business assets. Collateral should matter for two reasons. First, the posting of collateral helps reduce the riskiness of the loan to the bank, and thus has some bear ing on the first and third hypotheses for credit ration ing. Second, collateral can be considered as one of the determinants of pricing for the loans. Because collat eral has this dual role, we break it out separately from the risk and pricing terms above. We also control for other firm-level characteristics that might affect demand for funds. Age. represents the number of years that firm i has been in business and the number of years squared. If a younger firm faces more uncertainty about its growth prospects than an older firm, it is more likely to commit to a smaller line and use less of its line commitment. We also include dummy variables for the firm’s industry (IndustryI) and the state in which the firm is headquartered (State,). Although we have argued that we control for one potential problem—the difficulty in separating supply from demand—we may still face another problem. It Federal Reserve Bank of Chicago may be the case that omitted variables that affect loan supply happen to be correlated with the regressors, thereby biasing the coefficients. However, since we include all the variables observed by the financial in stitution, we are confident that the errors in the regression are not related to firm characteristics that might affect the bank’s supply of loans to the firm. Our approach in this regard is the same as that taken by Adams, Einav, and Levin (2009) for auto loans and Karlan and Zinman (2009) for other consumer loans. Results Table 3 presents the model estimates. Firms that have to pay higher upfront commitment fees, higher risk premium spreads, or higher usage fees commit to a smaller credit line, while firms that face a higher penalty for overdrawing their line commit to a larger credit line. All of the effects are economically large and statisti cally significant and jointly suggest that the quantity demanded is decreasing in the various pricing terms of the loan—that is, the demand curve slopes downward. An increase of 1 percent in upfront commitment fees decreases the line commitment by about 4 percent— a surprisingly large amount, given the relatively small average size of the fees. A 1 percentage point increase in the overcharge fee spread increases the amount of the credit line by more than 6 percent. Since 1 percent age point is large relative to the average penalty, but is well within the 5 percentage points standard deviation for that variable, normal changes in the spread lead to very large changes in the size of the credit line. A 1 per centage point increase in the interest rate—an amount slightly less than one standard deviation for that vari able—leads to about a 10 percent decline in the initial credit line, while an increase in the risk premium spread of 1 percentage point (about two standard deviations) reduces the initial credit line by about 18 percent. Proxies for net funding needs also have a very large impact on credit line demand. An increase in average net profit growth, which we would expect to be positively correlated with future need for funds, of 1 percent raises credit demand by about 16 percent. An increase of 1 percent in the standard deviation of net profit growth (which we would similarly expect to be positively related with the standard deviation of net funding needs) lowers credit demand by about 15 per cent. An increase in net cash flow of 1 percent lowers demand for credit by about 1.75 percent. Although this result has the right sign (since internal funds should reduce the net need for funds), its magnitude is small. Contrary to our expectations, having more working capital paradoxically raises credit line demand. This result may arise because working capital may be a 75 predictor of future funding needs.9 The net funding needs variables, as a group, have a larger effect on credit demand than any of the other explanatory variables, suggesting that the fourth hypothesis for what deter mines demand for loans under commitment—Martin and Santomero’s (1997) model of firms’ demand for flexibility in financing—plays an important role. An increase of 1 point on the risk rating (on an 8-point scale of increasing risk) lowers credit demand by over 1.5 percent. From Campbell (1978) and Hawkins (1982), we would have expected that firms fearing reductions in credit ratings would have demanded more credit. Our findings here do not support that idea, if we assume that already riskier firms are more concerned about deterioration. However, it is possible that rela tively less risky firms fear credit deterioration more, or pay relatively higher costs when their credit deteriorates. The use of collateral, not surprisingly, increases the demand for credit, more so when collateral is in the form of deposits rather than in the form of business assets. We also include, but do not report in the tables, other measures of firm characteristics that might affect credit demand. Younger firms hold larger lines of credit, perhaps because they fear deterioration in creditworthi ness; each additional year in business increases credit demand by about 2 percentage points. Firms whose industry classification places them in the finance, in surance, and real estate; trade; or service sectors have larger credit lines than those in mining and construc tion or manufacturing. There is no substantial variation in credit line size by state location. Credit line utilization Conditional on having chosen the size of the credit line, firms’ draws on the line should reflect the arrival of investment opportunities. But when firms must re peatedly choose lines, line usage should also influence the timing of such choices and the size of the line. If firms employ credit lines to give them the flexibility to take advantage of investment opportunities that would otherwise disappear, they should take out a new line before the current one is used up. We frequently ob serve this in our data: Firms convert the unused portion of the credit line into a spot loan and take out a new line of credit. Since utilization and the size of the credit line may therefore be jointly determined, we run the same regres sion as in table 3, replacing the size of the credit line with utilization (measured as a two-year average of the total amount drawn by the firm relative to the total credit line amount). The results, reported in table 4, are generally in line with expectations and the results reported in table 3. 76 TABLE 3 Demand for credit lines Intercept 93.39*’ (39.91) Price Log (commitment fee) -4.02*’ (1-02) Overcharge fee spread 6.42*’ (2.81) Interest rate -10.39*’ (4.09) Risk premium spread -17.83*’ (7.37) Net funding needs Mean net profit growth 15.88*’ (6.73) Standard deviation of net profit growth -14.67*’ (5.93) Log (net cash flow) -1.75 (1-21) Log (working capital) 7.80* (3.10) Risk Risk rating -1.59* (0.79) Collateral Collateral (deposits) 14.83* (5.92) Collateral (business assets) 4.17 (2.63) Firm characteristics included Years in business SIC dummies State dummies Yes Yes Yes Adjusted R-squared 0.68 Number of observations 637 ‘Denotes statistical significance at a 95% confidence level. “Denotes statistical significance at a 99% confidence level.

We find that higher upfront commitment fees are associated with greater usage of credit lines; a 1 percent increase in such fees raises utilization by about 4 percent.

Increases in interest rates and risk premium spreads lead to lower utilization rates, but the effects are much smaller than those for credit line size. The average and standard deviation of net profit growth affect utilization as expected—the former Federal Reserve Bank of Chicago increasing it (by 10 percent for each 1 percentage point increase); the latter decreasing it (by 11 percent for each 1 percentage point increase). Cash flow and working capital have negligible effects on usage, possibly be cause, conditional on having obtained the line, it is less costly for firms to use external funds (which must be paid for whether they are used or not) than internal funds. Riskier firms use smaller amounts of their credit lines; each one-step increase in risk category decreases line usage by about 3 percent. This may be consistent with the hypothesis that riskier firms are reluctant to use their credit for fear that credit will become more costly or unavailable if their condition deteriorates further. Collateral has a large but statistically insignificant effect on usage. There is no economically or statistically significant variation in utilization by age of the firm, industrial classification, or state location. Conclusion Firms borrow in order to undertake investment or to insulate themselves from macroeconomic shocks, among other reasons. Thus, a better understanding of firm borrowing not only allows us to better model in dividual firm behavior, but also may enhance our abili ty to understand business cycles. Credit lines are an important source of borrowing, especially for small firms. There are several competing explanations for the existence and use of credit lines: hedging against deterioration in creditworthiness, hedging against aggre gate reduction in credit, solving informational prob lems that make it hard for firms to borrow in other markets, or providing speed and flexibility to enable firms to take advantage of investment opportunities. Although a number of researchers have looked at the determinants of the supply of credit lines, few have looked at demand; those that have looked at demand have analyzed publicly traded firms, for which data are more readily available. In this article, we look at the demand for credit lines by privately held firms. Our findings are consis tent with predictions derivable from several models of credit line usage. Firms facing higher upfront com mitment fees, risk premium spreads, or usage fees have smaller credit lines, while those with higher overdraft fees have larger ones. Firms with greater profit growth in the past have larger credit lines, while those with more internal funds or higher volatility in profit growth have smaller credit lines. The results for line utilization are quite similar. We also find that firms rarely exhaust their credit lines; rather, they convert the unused por tions of their credit lines to spot loans and take out new lines. This last finding suggests there is a dynamic in teraction between line size and usage; it would be of 77 interest to model this relationship in order to develop new predictions and to link the estimates of firm bor rowing behavior more directly to models of economic fluctuations. Finally, although we have tried to separate the determinants of demand from those of supply, we have likely not done so perfectly. Thus, some of the effects we identify may also reflect factors that affect loan supply.

Federal Reserve Bank of Chicago 79 Fourteenth Annual International Banking Conference The Role of Central Banks in Financial Stability: How Has It Changed? November 10-11,2011 Federal Reserve Bank of Chicago In conjunction with the European Central Bank, the Federal Reserve Bank of Chicago will hold its fourteenth annual International Banking Conference on November 10-11, 2011, at the Bank. The purpose of the annual conference is to address important current issues affecting international financial markets. This year, we will examine the changing role of central banks in pursuing financial stability. Prior to the recent financial crisis, there were significant differences across countries in how and to what extent financial stability was pursued by central banks. In some countries, the central bank had an explicit stability objective but did little to actively manage stability other than to ensure liquidity access, out of fear that more active involvement might distort markets. In other countries, the central bank prepared formal stability reports and/or pursued financial stability more actively. Following the global financial crisis, significant reforms have been initiated in many coun tries to address financial stability more directly, frequently focusing on macroprudential policy frameworks in which central banks play a more active role. We are interested in examining a number of important issues associated with the recent change in emphasis at central banks with regard to financial stability. For example, what were the cross-country differences in emphasis on financial stability in the past? Did these differences appear to affect the extent of the adverse impact of the crisis on individual countries? Can systemic risk be measured and identified? What alternative macroprudential policy tools have been introduced to address systemic risk? Have views changed on how to address sources of financial instability, including asset bubbles? What are perceived to be the major future threats to financial stability? Did the financial sector grow too big within the pre-crisis financial architecture from a social cost-benefit perspec tive? Might the pursuit of financial stability have adverse societal welfare implications if certain financial activities or innovations are limited or prohibited? How potentially effective might recently introduced reforms be at achieving their stated goals? What major “gaps” still exist? These and related issues will be addressed at the two-day conference. As at past conferences, the emphasis of the conference will be on the implications for public policy. The conference will feature keynote presentations by Janet Yellen, Vice Chair of the Federal Reserve System; Mario Draghi, Governor of the Banca d’Italia (invited); and Axel Weber, former President, Deutsche Bundesbank (invited). As usual, the makeup of the conference will truly be international. Participants from some 35 countries regularly participate in the conference and include representatives of central banks, regulatory and supervisory agencies, financial institutions, trade associations, and academic institutions from around the globe. We invite you to participate in this important event. Additional information, includ ing the full agenda and conference and hotel registration details, will be posted on the conference website as it becomes available: www.chicagofed.org/lnternationalBankingConference We hope you can join us in Chicago in November.
