F ed eral R eserve Bank of St. Louis Review November 1985 In This Issue . . . In the first article of this Review, M ichael T. Belongia and C ourtenay C. Stone investigate the validity of a conventional policy recom m en d ation am ong agricul tural econ om ists: that red u cin g the federal budget deficit is a n ecessary co m p o nent of any effort to increase agricultural exports. W hile widely a ccep ted , Belon gia and Stone argue that at least three propositions m ust be tru e for this recom m en d ation to have som e legitim acy. The first two propositions require positive relationships betw een deficits and the real rate of interest an d betw een the real rate of interest and the real value of the dollar. The last proposition requires a negative relationship betw een the real value of the dollar and real farm exports. Belongia and Stone investigate these propositions by explaining the relevant eco n om ic theory behind each and offering both sim ple an d detailed statistical evidence regarding the predictions of these theories. Their analysis indicates there is considerable doubt that larger budget deficits have raised real interest rates and, consequently, the real value of the dollar. They do find su p p ort for the third proposition relating the exch an ge rate to farm exports. In view of the o th er conflicting evidence, however, the authors co n clu d e that it is safe to say the relationship betw een budget deficits and farm exp orts is unresolved. In the secon d article in this issue, "M onthly E co n om ic Indicators: A Closer Look at the Coincident Index,” Keith M. Carlson d iscu sses the C om m erce D epart m en t’s com p osite index of coincident indicators. This index co n d en ses the inform ation from the m ost im portant m onthly e co n om ic ind icators into one sum m ary m easure. The co m p o n en t indicators from w hich the co m p o site index is derived include em ployees on nonagricultural payrolls, personal incom e less transfer paym ents in con stan t (1972) dollars, industrial produ ction , an d m an u fac turing and trade sales in co n stan t (1972) dollars. After describing the coinciden t index and its co m p o n en t indicators, Carlson d iscu sses the C om m erce D ep artm en t’s scoring system . This system is b ased on seven criteria. The focus of the article, however, is on the criterion of cyclical p erform ance. An exam ination of the co m p o n en t ind icators reveals th at each ind icator generally conform s well with the National Bureau of E co n om ic Re search 's business cycle reference points, particularly w hen viewed with som e perspective. 3 Would Lower Federal Deficits Increase U.S. Farm Exports? Michael T. Belongia and Courtenay C. Stone NY farm policy experts believe that U.S. agri cultural exports w ould be increased significantly if federal budget deficits w ere red uced . One su ch ex pert, for exam ple, has co m m en ted that “a m ore nearly balanced federal budget probably w ould do as m uch as anything to im prove o u r agricultural export perfor m an ce.”1 O ther analysts also have predicted that the farm outlook will rem ain bleak until this nation d e velops “a credible plan to red u ce the en orm ous Fed eral budget deficits.”- This view is so pervasive that it might now be con sidered the conventional wisdom on the subject.' If this view is valid, it has im portant im plications for d om estic farm policy legislation, including the p en d ing farm bill.1 If federal budget deficits have seriously red u ced farm exports and, consequently, real farm incom e, then legislators should focus primarily on reducing the deficit to revive farm exports and incom e; in this case, cu rren t com m odity program s may need little fundam ental change o nce the deficit has been red u ced . If budget deficits have not contributed m ate rially to the decline in farm exports, however, then focusing attention on deficit red u ction m easures may Michael T. Belongia and Courtenay C.

It is held by a large number, perhaps even the vast majority, of policy analysts. For similar statements about the effect of deficits on exports, see Clark (1985), Downs (1985), Kraft (1985) and Modigliani (1985). “The omnibus farm legislation currently in effect is a four-year bill that was passed in 1981.

The purpose of this article is to describe the theoretical links betw een federal budget deficits and U.S. farm exports and to exam ine the em pirical evidence on these links. THE FARM E X P O R T PR O BLEM singled out as a strong, p erh ap s the prim aiy, suspect in attem pts to explain w hy farm exp orts have declined so sharply in recen t years. A p rim a fa c ie case can be m ade for the deficit explanation bv simply looking at the recent relationship betw een exp orts and the defi cit; this com p arison is show n in ch art 1 for sem i annual data since 1973. If we look only at the past four years, we see that nom inal farm exp orts declined from 1981 through 1983, rose marginally last year, and have fallen again through early 1985. During this sam e period, federal deficits, as m easured by the national incom e a c counts, skyrocketed, rising from $64 billion in 1981 to $176 billion in 1984. The association betw een rising deficits and falling exp orts app ears to be obvious. Yet, w hen the entire period is exam ined, this co n clusion is not so obvious. Deficits w ere rising and falling from 1973 (when it w as only $6 billion) to 1981. This period w as one of generally rising farm exports. Thus, the view that rising deficits adversely affect exp orts is one that seem s to be based primarily on evidence from the m ost recen t period. Such a narrow focus necessarily raises questions about the generality of the presum ed relationship and the likely effect of policies designed to exploit the relationship. To get a b etter perspective on the relationship b e tween deficits and farm exports, w e m ust focus on the 5 FEDERAL RESERVE BANK OF ST.

TH E LINKS IN T H E D EFICIT-FARM E X PO R T CHAIN The conventional view of the links betw een deficits and farm exp orts is show n in figure 1. In this fram e work, the problem s of red u ced exports, expan d ed im ports and political m easures prom oting protection for d om estic industries can be traced backw ard, stepbv-step, to their so u rce: large, persistent federal budget deficits. An exam ination of figure 1 show s that there are at least three key eco n om ic relationships that m ust exist for this conventional view to be valid. First, o th er things unch an ged, deficits m ust be re lated system atically to real interest rates (interest rates 6 79 80 81 82 83 84 1985 adjusted for exp ected inflationl; specifically, higher deficits m ust raise real interest rates and low er deficits m ust red u ce them . Second, real interest rates m ust be related system atically to the real foreign exchange value of the dollar (the dollar’s value after adjusting for differences in inflation betw een the United States and foreign countries); higher real rates m ust raise the dollar’s real value an d low er real rates m ust red u ce it:' Third, the real foreign exch an ge value of the dollar m ust be related system atically to real agricultural ex ports (agricultural exp ort receip ts ad ju sted for m ove m ents in the general p rice level); higher real exch an ge rates m u st red u ce real farm exp orts and low er e x change rates m ust increase them . The con clu sion that 5 More correctly, the second link refers to the impact of higher real interest rates in the United States vis-a-vis those in other countries. This is explained later in this article. FEDERAL RESERVE BANK OF ST.

We analyze these links in turn in the following sections. LINK # 1 : WOULD LO W ER D EFIC ITS REDUCE REAL IN T ER EST RA TES? Choosing Appropriate Deficit and Interest Rate Measures One basic problem with tiying to discern the rela tionship betw een deficits and interest rates is that the m easures w e observe m ust be "ad ju sted ,” both to eliminate potentially confounding influences and to focus the analysis on those m easures that are em p h a sized by the underlying eco n om ic theoiy. The deficit m easure can be adjusted in a variety of wavs. Three com m only used p ro ced u res are: (1) to adjust for the im pact of inflation by using a real deficit m easure; (2) to adjust for the size of the econ om y by dividing the deficit by som e m easure of spending o r saving; and (3) to rem ove the business cycle influences on the deficit. Interest rates also m ust be adjusted appropriately if we are to cap tu re the deficit's influence on them . Market interest rates — the ones that we see quoted every day — ca n be thought of as the sum of two basic com p on en ts: the exp ected inflation rate and the ex p ected (or ex a n te) real rate of interest." Changes in the deficit per se should have no effect on the exp ected rate of inflation unless the Federal Reserve is exp ected to m onetize the deficit (that is, increase its p u rch ases of governm ent bonds).7 Since ch an ges in the exp ected rate of inflation, how ever, cau se nom inal interest rates to change an d obscu re the im p act of ch an ges in the deficit, w e m ust rem ove the influence of ch an ges in inflation exp ectation s; w e m ust focus on the deficit’s im pact on the exp ected real rate of interest. The Conventional View o f the Deficit’s Impact on the Real Rate o f Interest The view that larger deficits increase the exp ected real rate of interest is based on the validity of the "interest-rate crow ding o u t” p h en om en on. Interestrate crow ding out is d em onstrated graphically in 6For discussions of the differences between nominal and real interest rates and between ex ante and ex post interest rate measures, see Santoni and Stone (1981a, 1981b and 1982); for an analysis of the problems associated with attempts to measure real interest rates, see Brown and Santoni (1981). 7For evidence that larger deficits per se are not associated with faster inflation, see Protopapadakis and Siegel (1984) and Weintraub (1981). 7 FEDERAL RESERVE BANK OF ST. LOUIS figure 2, w hich depicts the d em an d for and supply of real resou rces allocated through credit markets. The dem and curve, labeled D, is the dem and for resources by w ould-be borrow ers: con su m ers, private firms and, of cou rse, the governm ent. The supply cuive, labeled S, rep resents the am ou nt of cu rren t saving that w ouldbe lenders (savers) are willing to provide. The price that influences th ese borrow ing and lending decisions separately, and that is determ in ed jointly by the inter actions of all borrow ers and lenders, is the real rate of interest. NOVEMBER 1985 F ig u re 2 Com parison o f D e f i c i t ' s I m p a c t o n In t e r e s t R a t e s Using figure 2, it is easy to show how a larger deficit could increase the real rate of interest. If all oth er things rem ain the sam e, a larger deficit increases the dem an d in the credit m arket to D' and results in a higher price of credit as the real rate of interest rises to r,. The additional resou rces that the governm ent ob tains com e partly from additional saving (for exam ple, people red u ce their consum ption) and partly from reductions in non-governm ent borrow ing (for exam ple, private investm ent declines). The larger deficit and the resulting higher real interest rate have thus crow ded out, or red u ced , private secto r consum ption and investment. Of course, the extent to w hich the real rate of inter est actually in creases u n d er the conventional view d epends on the specific slopes of the dem and and supply cuives; the flatter are the dem and and supply curves, the sm aller the rise in the real rate of interest. An Alternative Theoretical View o f the Impact o f Deficits Interest-rate crow ding out, as d ep icted in figure 2, is predicated on the view that increases in the deficit per se have little effect on the supply of o r the dem and for credit bv co n su m ers and private firms. Instead, co n sum ers and private firms respon d by moving along their u nchanged dem an d and supply cuives in re sponse to changes in the real rate of interest p rodu ced by the increased governm ent deficit. An alternative view of how people respon d to changes in governm ent deficits suggests that the real rate of interest is essentially unaffected by governm ent deficits." This view states that people see deficits as T h is view has been popularized by Barro (1974) and Seater (1982), among others. For a recent discussion of the conventional and alternative theoretical relationships between deficits and interest rates, see Rasche (1985) and Tatom (1985); for recent evidence supporting this alternative view, see Kormendi (1983) and Protopapadakis and Siegel (1984). 8 implied taxes that eventually m ust be im posed on their future incom es to repay the larger governm ent obligations. Thus, larger deficits today are equated with larger future taxes an d red u ced future after-tax incom es. As a result, an increase in the deficit red u ces peop le’s perm anent incom es; this, in turn, red u ces the private land, thus, the total) dem an d for credit (to D), while increasing private saving and, thus, the su p ply of credit (to S). As show n in figure 2, although defi cits crow d out private investm ent an d consum ption, they have no appreciable im pact on the real rate of in te re st, w h ich re m a in s u n ch a n g e d at r„. The crow ding-out is d irect; it does not take p lace through increased real interest rates. Deficits and Expected Real Interest Rates: Some Casual Evidence The conventional view suggests that, o th er things the sam e, larger deficits are associated w ith higher exp ected real interest rates; the alternative view sug gests that they are not. Chart 2 displays the behavior of one adjusted deficit m easure and one m easure of the e x p ected real inter est rate that, accord in g to conventional theory, is in fluenced by federal deficits. The deficit m easure used is the real cyclically adjusted deficit div ided by p oten FEDERAL RESERVE BANK OF ST.

These expected inflation figures were then subtracted from the quarterly averages for the six-month Treasury bill rate for the quarters in which the surveys were taken. For more details on this method, see Holland (1984). 79 80 81 82 83 84 1985 twice as high in the later y ears than it w as in the earlier years. Similarly, the exp ected real rate rose sp e cta cu larly from early 1980 to early 1982 w hen the deficit m easure w as virtually u n ch an ged ; since then, the real rate has declined considerably, vet the deficit has clim bed substantially. Chart 3 sum m arizes the relationship betw een the deficit and the real interest rate in an alternative fash ion. It is a scatter-d iagram of the associated ch an ges in the deficit and ante real interest rate m easures. If increases (decreases) in the deficit generally w ere as sociated with increases (decreases) in real interest rates, then the vast m ajority of the associated pairs of deficit-interest rate ch an ges w ould be in the first (1) and third (III I quadrants of the ch art. As a perusal of ch art 3 indicates, however, the points are scattered fairly random ly with half of them in the “w rong" parts of the chart.

The conventional theoiy suggests that the line should slope upw ard from left to right in ch art 3; in fact, it does not. The slope, however, is not statistically significant. Thus, a simple analysis suggests that ch an ges in the deficit have no significant effect on m ovem ents in the real rate of interest.

LINK # 2 : WOULD LO W ER U.S. REAL IN T ER EST RATES RED UCE TH E FOREIGN EXCHANGE VALUE O F TH E DOLLAR? Most farm com m odities trad ed in international m arkets are priced in U.S. dollars regardless of w here they are p ro d u ced . Consequently, a set of events that raised the value of the dollar in term s of Brazilian cruzeiros, for exam ple, w ould make Brazilian soy beans less expensive than U.S. soybeans. Nations that im port soybeans cou ld use their dollars to p u rch ase cruzeiros and, hence, p u rch ase Brazilian soybeans m ore cheaply than before. B ecause of this relation ship, changes in farm exports are linked to changes in the value of the dollar. While we typically think of the value of the dollar visa-vis one or an o th er specific cou n try's cu rren cy — for exam ple, the Jap an ese yen, the Fren ch franc o r the West German mark — su ch bilateral exchange rates bv them selves, do not provide a clear picture of w hat is happening to the overall value of the dollar in foreign exchange m arkets. Instead, an /nde,v of the dollar’s value often is used to incorporate information about the m ovem ent of the dollar relative to o th er m ajor cu rrencies. One index, called the trade-w eighted ex change rate of the U.S. dollar, enables us to determ ine what is happening to the dollar's value relative to the cu rren cies of o u r m ajor trading p artners." The foreign exch ange value of the dollar is the relative price of the U.S. dollar in term s of o th er n a tion s’ cu rren cies. The actu al value of the dollar at any time is d eterm ined by the factors that underlie the dem and for and supply of dollars in foreign exchange m arkets. There currently is som e controversy over w hich factors determ ine exch an ge rates and the relative in fluences they have on exchange rate m ovem ents at 1 For a detailed discussion of the major problems associated with 3 empirical estimation of the deficit's impact on interest rates, see Congress (1985a), pp. 77-84. ,4The trade-weighted exchange rate used in this study is the Federal Reserve Board index (March 1973 = 100) of the weighted-average exchange value of the U.S. dollar against the currencies of other G10 countries plus Switzerland. Weights are the 1972-76 average total trade shares of each of the 10 countries. 12 NOVEMBER 1985 any p articu lar m om ent.' There is, however, a fairly general analytical framework that suggests four fac tors as the main influences on the behavior of ex change rates: (1) differences in inflation rates betw een countries; (21 differences in real interest rates betw een countries; (3) differences in real eco n o m ic conditions that influence trade p attern s; and (41 differences in political and o th e r risks associated w ith investm ent in specific countries."' We focus on the effects of changes in the first two factors on exch an ge rate m ovem ents. Unfortunately, ch an ges in the rem aining two factors can make it difficult to d ecip h er the actu al im p acts of changes in inflation an d real interest rate differentials on the exch an ge rate at any given m om ent. Adjusting the Exchange Rate fo r Differences in Inflation Across Nations Theoretical co n sid eration s suggest that ch an ges in bilateral and trade-w eighted foreign exch an ge values of the dollar are inversely related to differences be tw een U.S. and foreign inflation rates. If this inflation differential (U.S. m inus foreign) is positive, the value of the dollar will decline over tim e; if the inflation differ ential is negative, the dollar’s foreign exch an ge value will rise. This relationship, called pu rch asin g p ow er parity, is based on the notion that sim ilar goods traded in world markets m ust co m m an d sim ilar prices, regardless of w here they are bought and sold. F or exam ple, if a bushel of corn co sts $1.50 in the LInited States and C3 in the United Kingdom, an exch an ge rate of £ 2 per dollar w ould "equalize” the price of U.S. an d U.K. corn to all p u rch asers. If inflation in the United States drove the price of corn to S3 p er bushel, then, o th er things the sam e, the exchange rate w ould have to fall to £ 1 per dollar to bring the price of U.S. co rn back in line with U.K. corn in w orld m arkets. Of course, if changes in the value of the dollar were simply the result of ch an ges in these inflation differen- ,5For example, one analyst has noted that “there is no consensus on how exchange rates are determined. The interpretations vary widely among the various theories, ranging from the traditional approach of trade-oriented demand and supply factors, to the modern approach of asset-market mechanism and expectations. The analysis of cur rency determination is complicated by the interdependence of the exchange rates, monetary and other economic policies, and factors affecting economic and financial performance.” Poniachek (1983), p. 2.3.3. "This discussion is based on the framework developed in Isard (1980). FEDERAL RESERVE BANK OF ST. LOUIS tials, exchange rate m ovem ents w ould be neutral with respect to trade p atterns. Indeed, o th er things u n changed, exchange rate m ovem ents con sisten t with purchasing pow er parity will preserve cu rren t trade patterns. Exchange rates are affected bv o th er factors, how ever, so that their m ovem ents are not con sisten t solely with purchasing pow er parity conditions. If exchange rates rise m ore (or fall less) than inflation differentials w arrant, prices of U.S. goods will rise relative to similar goods sold by o th er cou n tries; if exchange rates rise less (or fall more) than inflation differentials w arrant, prices of U.S. goods will fall relative to foreignp rodu ced goods. This discussion suggests that, if we want to assess the effect of exchange rate m ovem ents on exp orts in general, and farm p ro d u cts in particular, w e should look at the m ovem ent in exch an ge rates after adjusting for the effects of inflation differentials. One su ch ex change rate m easure is called the real trade-w eighted exchange rate for the U.S. dollar.'7 The Impact o f Real Interest Rate Differences on the Real Exchange Rate Theoretical con sid eration s suggest that changes in the real trade-w eighted exchange rate should be posi tively related to ch anges in the real interest rate differ ential (U.S. m inus foreign). If U.S. real interest rates rise relative to foreign real rates, o th er things the sam e, the real trade-w eighted value of the dollar should rise; if U.S. real interest rates fall relative to foreign real rates, the real trade-w eighted value of the dollar should decline. The presum ption is that a positive real rate differential will attract foreign capital, while a negative differential will make investm ent abroad m ore a ttra c tive. Thus, ch an ges in the real rate differential should cau se similar ch an ges in the real trade-w eighted ex change rate.

It is a scatter-d iagram of changes in the real interest rate differential and the associated per cen t changes in the real exch an ge rate. O ther things unchanged, eco n om ic theoiy predicts that the points should lie predom inantly in the first (I) and third (III) quadrants; positive (negative) ch an ges in the real in terest rate differential should be associated with posi tive (negative) p ercen t ch an ges in the real exchange rate. This is not the case: the data points lie mainly in quadrants II and IV. The line labeled R, is the regression line relating the p ercen t ch an ges in tire real trade-w eighted exchange rate associated with the ch an ges in the exp ected real interest rate differential. It should slope upw ard from left to right; instead, it slopes dow nw ard, suggesting that an increase (decrease) in the real interest rate differential is associated with a d ecrease (increase) in the real exch an ge rate. This estim ated inverse rela tionship, however, is not a statistically significant one; that is, the claim that there is no sim ple linear relation ship betw een these variables can n ot be rejected at standard statistical significance levels. This puzzling result again suggests that d eciphering the effect of changes in real interest rate differ entials on exchange rate m ovem ents requires detailed and careful e co n o m etric analysis. Some Econometric Eiidence Em pirical studies of real exch an ge rates and real interest differentials offer a som ew hat qualified view of their relationship.

Specifically, the study foui that a 10-basis-point change in the U.S. m inus foreij real interest differential w ould cause, after two qua ters, a 0.23 p ercen t rise in the real value of the dollar. This study also found no independent effect of deficits on the real exchan ge rate.-' In general, it ap p ears that w e know very little about the extent to w hich real interest rate differentials actually affect real exchange rates. ,9Batten and Belongia (forthcoming 1986). “ The estimated coefficients from this type of statistical study are strictly valid only for small changes in variables. Therefore, the example presented should not be expanded to conjecture, for example, that a 100-basis-point change in the interest differential would cause a 2.3 percent change in the dollar’s real value. 2 Similar results were found by Bisignano (1985). 1 14 79 80 81 82 83 84 1985 LINK # 3 : WOULD A LO W ER VALUE O F TH E DOLLAR INCREASE U.S. FARM EXPO RTS?

O ther things unchanged, e co nom ic theoiv predicts that the points should lie p re dom inantly in the secon d (III and fourth (IV) quad rants; positive (negative) changes in the real exchange rate should be associated with negative (positive) changes in real farm exports. This, however, is not the case: the data points are random ly scattered through out the four quadrants and nearly half of them lie in the w rong ones. The line labeled R, is the regression line relating the p ercent changes in real farm exports associated with the p ercen t changes in the real exch an ge rate. It should slope dow nw ard from left to right and it does. The negative slope, however, is not statistically signifi can t. Thus, the possibility that there is no co n tem p o ran eous relationship betw een ch an ges in the ex change rate and farm exp orts can n ot be rejected. 16 Some Econometric Evidence Em pirical studies have show n that changes in the real exch an ge rate do affect im ports and exp orts over a considerable tim e period.

Thus, if frequently is argued that ou r n atio n ’s exporting sectors, p rod u cers of farm com m odities in particular, will continue to suffer until federal deficits are red u ced an d U.S. interest rates are brought down. In this article, w e exam ined three vital links in the conventional argum ent that ties the deficit to farm exports. With resp ect to the first link, w e noted that there is considerable theoretical controversy over w heth er larger deficits actually cau se real interest rates to increase. We found little em pirical evidence to support this view. Second, w e noted that, even if low er deficits did result in low er U.S. real interest rates, they w ould not necessarily have a salutary im p act on the real ex change rate. Apparently, o th er influences on the real exchange rate have offset the effect, if anv, of changes in real interest rate differentials in recent years. Among these o th er factors m ay be "the strong perfor m an ce of the U.S. econom y, confidence in the strength and stability of the political system in the United States, capital flight from debtor countries, [and] a substantial shift in the external position of Am erican banks. ” 6 The im portant point is that there is little 2 2 Pohl (1985). Similar comments have been made by a wide variety of 6 commentators: e.g., “At various times, other factors, which are difficult to measure, have also influenced the d o lla r... The reversal 18 em pirical evidence to show that ch an ges in the real interest rate differential have had a significant im pact on m ovem ents in the real exch an ge rate during the past 13 years. Finally, w e show ed that, although U.S. farm exp orts are inversely related to the real exch an ge value of the dollar, the dem an d relationship is inelastic and ex change rate m ovem ents have th eir full effect only over a considerable tim e period. However, even though low er exch an ge rates would, over time, increase U.S. farm exports, the failure of the first two links to be supported suggests that w e can n o t necessarily expect that low er deficits will result in a low er value of the dollar in foreign exch an ge markets.-7 None of the d iscussion above should be taken as evidence that deficits p er se are eith er good or h arm less. Nor does it prove that larger deficits have had no adverse effect on real interest rates, on the foreign exchange value of the dollar o r on farm exports. Unfor tunately, at the present tim e, there con tin u es to be in the dollar's fortunes since late 1980 may [be] related to (i) the election of a new administration committed to a more conservative approach to financial policies; and (ii) the increased risks associated with other currencies."

Recent eco n om ic perfor m an ce is a vital foundation required in the p ro cess of deciding w hat co u rse m on etary policy should take. There are m any eco n o m ic indicators released each m onth, and one problem for the m on etaiy policy maker, as well as for businesses, con su m ers and gov ernm ents, is to distill from this spate of inform ation som e assessm en t of just how well the econom y is performing. The U.S. D epartm ent of C om m erce's B usiness Con ditions Digest lists 84 different eco n om ic time series as m onthly cyclical indicators. An analysis of all, or even a substantial subset, of these indicators could provide a confusing picture to even the m ost astu te analyst.

All of the co m p o n en ts of the coin ciden t index ap p ar ently are classified as being included in (1) or (2).

Statistical Adequacy How well does the given series m easure the e co n om ic variable o r p ro cess in question? The BEA co n siders eight asp ects of this criterion: (1) Quality of the reporting system — is it set up for statistical purp oses or is it the by-product of an adm inistrative program ? (2) Coverage of eco n o m ic p ro cess — full en u m era tion, probability sam ple, etc. (3) Coverage of time period — full m onth or quarter, one day per m onth, etc. (41 Availability of estim ates of sam pling and rep o rt ing errors. (51 Frequency of revisions. (6) Length of series. (7) Comparability over time — breaks in the series. (8) O ther considerations. This detailed evaluation is co n stru cted to be primarily quantitative rath er than qualitative. Cyclical Timing How consistently does the series coincide w ith su c cessive business cycle turns? B ecau se this criterion is crucial for timely recognition of business cycle turning points, it is assigned the greatest weight of all the criteria. A ccording to the BEA, this criterion has four phases: (1) identification and dating of specific cycles for the com p on en t series; (2) deciding on reference dates (depending m ainly on the reference chronology established by the NBER); (3) m atch in g the specific cycle turning points with the reference dates; and (4) scoring the cyclical perform an ce of the p articular indicator. Conformity How regularly do m ovem ents in the specific in d ica tor reflect the expansions an d co n tractio n s of the 23 FEDERAL RESERVE BANK OF ST. LOUIS overall econ om y? For an ind icator to be useful, its specific cycles m ust parallel business cycles. C on formity is defined positively if the ind icato r rises d u r ing eco n om ic expansions and declines during co n tractions, and negatively if it m oves countercyclically. This evaluation consid ers the n um ber of business cycle phases and how they are m atch ed bv the cycle m ovem ents of the particu lar indicator. Also exam ined are false signals associated with specific cycles; that is, m ovem ents in the indicators that do not m atch gen eral expansions an d co n tractio n s. In addition, there is a consideration of am plitude. F or exam ple, larger m ovem ents than the average will tend to be m ore identifiable, thu s contributing to the usefulness of an indicator. Smoothness How prom ptly can a cyclical turn in a series be distinguished from a directional change associated with sh o rter m ovem ents? It is desirable that the cycli cal m ovem ents of the ind icator are not obscu red by relatively large and frequent irregular variations. Al though there are o th er ways of improving sm ooth n ess (for exam ple, by calculating a moving average), gen er ally su ch p ro ced u res imply a loss of tim eliness. Timeliness How prom ptly available is the particu lar series and how often is it reported ? Two asp ects are considered: (1) how frequently the figures are com piled, and (2) how prom ptly the figures are available. NOVEMBER 1985 Depending on the total perform ance score, weights are assigned to ea ch in d icator in the co n stru ction of the com p osite index. F or exam ple, nonagricultural em ploym ent receives the greatest weight (1.064) be cau se of its 87 score, followed by industrial p roduction (1.028), personal incom e less transfer paym ents in con stan t (1972) dollars (1.003), and m anufacturing and trade sales in co n stan t (1972) dollars (.905). These weights do not differ markedly, although the dif ference betw een the largest and the sm allest is substantial. Nonagricultural em ploym ent sco res high on all cri teria, followed closely by industrial p rodu ction . A c cording to table 2, the weight on industrial p roduction is red u ced by its perform an ce at cyclical peaks and by the extent to w hich it is revised. Personal incom e receives a relatively low score, mainly b ecau se of the revisions. Clearly, the w orst of the co m p o n en ts is m an u factu rin g an d trad e sales, w hich generally scores low est by ea ch criterion. The scores for the co n stru cte d com p osite index are som ew hat surprising. In particular, the total sco re is low er than that of both nonagricultural em ploym ent and industrial p rod u ction . Apparently, this reflects the fact that the com p osite index is subject to su b stan tial revision, since it has to be revised every tim e any one of the co m p o n en t series is revised. CYCLICAL PERFORM ANCE How large are the revisions? This criteria w as added separately to the list prep ared by Zarnow itz and B oschan in 1975. Series that are subject to large revi sions, especially if they involve directional change, can be troublesom e, providing m isleading signals about the p ace of eco n om ic activity. The m ost im portant criterion used in the evaluation of eco n om ic indicators is the cyclical perform an ce of the ind icator in question. Generally, to be classified as a coinciden t indicator, an in d icato r m ust turn on average betw een —3 (3-m onth lead) an d + 1 (1-m onth lag) at peaks and betw een —1 an d + 3 at troughs. The differences at peaks an d troughs reflect the historical distribution of timing. Specific peak and trough dates for each of the coinciden t indicators are sum m arized in table 3. TH E BEA SCORING SUMMARY FO R TH E COINCIDENT INDEX Specific Cycles vs. Reference Dates Revisions The scores show n in table 2 cover the period from 1948 to 1980. The BEA’s objective w as to develop a com posite index that red u ces the n um ber of false signals that m ight arise if one w ere to rely on a single indicator. The advantage of a com p osite index is that it will sm ooth out the noise in the co m p o nen t series and also cap tu re the different eco n om ic p ro cesses rep re sen ted — produ ction , em ploym ent, real incom e and real sales.

'No specific cycle, that is, no specific turning point corresponding to the indicated reference is discernible. T here is considerable variation in the lead-lag time for the co m p o n en t indicators, although the range gen erally is sm allest at cycle troughs.

The index of industrial p rodu ction has an excellent record around reference dates, especially the trough dates. It is not clear, therefore, w hy the BEA scores this ind icator so low arou n d cycle peaks, but it m ay be due to subsequent revisions arou n d su ch dates.

W hen quarterly averages of the com p on en t in d icators are co m p ared with GNP, real personal incom e less transfer paym ents correlates m ost highly, followed closely bv industrial produ ction . SUMMARY M any e co n om ic ind icators are potential can d id ates for inclusion in a list of sensitive m easures of the econom y's cyclical m ovem ents. To simplify the p ro cess of selection, th e Bureau of E co n o m ic Analysis of the U.S. D epartm ent of C om m erce has co n d en sed the list to four key indicators and, in turn, has co n stru cted a single com p osite index of coin cid en t indicators. This article describes the com p osite index and its four com p onen t indicators, with special focus on their cyclical perform ance. The four co m p o nen ts of the coinciden t index are industrial produ ction, nonagricultural em ploym ent, real personal incom e less transfer paym ents, and real m anufacturing an d trad e sales. These four w ere rated highest by the BEA using a scorin g system based on 28 seven criteria. On the basis of these criteria, no single ind icator dom inates the others as a m onthly ind icator of eco n om ic conditions. F o r the casual e co n om ic analyst, the least satisfactoiy ind icator w ould be real m anufacturing and trade sales becau se, of the four series, it is the m ost volatile on a m onthly basis. Also, it is slow to be released; the estim ate for a p articu lar m on th is not available until a m onth and a half later. The release lag for two of the oth er series is about one w eek for nonagricultural em ploym ent an d about 15 days for industrial p ro d u c tion. Although the basic d ata for real personal incom e less transfer paym ents are released in about 20 days, the inflation-adjusted series is not released until the end of the m onth for the preceding m onth. The co m posite index is released at the end of the m onth, but the first estim ate for the preced in g m onth is based on only three of the co m p o n en ts; b ecau se of the rep o rt ing lag, real m anufacturing an d trad e sales is exclu d ed from this first estim ate. An exam ination of th e cyclical perform an ce of the coinciden t index and its co m p o n en ts revealed that each series generally con form ed well with the NBER business cycle reference dates. This result is not su r prising, since turning points in eco n o m ic activity are am ong the m ost im p ortan t criteria used in the se le c tion of coinciden t series. NOVEMBER 1985 FEDERAL RESERVE BANK OF ST. LOUIS One key question relating to the cyclical reliability of an indicator is the extent to w hich it em its false sig nals. An exam ination of m onthly m ovem ents of the indicators show s that they do, in fact, give false sig nals, betw een 15 p ercen t and 30 p ercen t of the time. All of the indicators perform very well, however, w hen false signals are defined as three successive m on th s of perverse movement. Finally, som e insights into the com parative perfor m an ce of the coinciden t indicators w ere gleaned from simple correlation analysis. This analysis indicates that nonagricultural em ploym ent and industrial p ro d u ction are m ost closely related on a m onthly basis with the com posite index. These two co m p o n en t se ries also receive the greatest weight in the co n stru c tion of the index. On a quarterly basis, however, real personal incom e less transfer paym ents correlates m ost highly with real GNP. Real m anufacturing and trade sales generally perform s least satisfactorily.

APPENDIX Detailed Discussion of the Component Series of the Coincident Index Employees on Nonagricultural Payrolls Personal Incom e Less Transfer Payments in Constant (1972) Dollars This series m easures the n u m ber of persons em ployed in nonagricultural establishm ents. Data are obtained from the establishm ent survey co n d u cted each m onth by the Bureau of Labor Statistics. The data are primarily from payroll record s voluntarily rep orted each m on th to state em ploym ent security agencies by em ployers in the 50 states and the District of Columbia. Most of these d ata relate to the payroll period that includes the 12th of the m onth; data for federal governm ent em ployees represent positions o ccu p ied on the last day of the m onth. Included are full-time, part-tim e, tem p oraiy and perm an en t w orkers. W orkers on paid leave and those w ho w orked part of the pay period are in cluded. Persons on the payroll of m ore than one establishm ent are co u n ted each tim e they are re ported. E xclu d ed are p ersons on nonpav status for the entire period due to layoff, strike or leave w ith out pay; the self-em ployed an d unpaid volunteer and family w orkers; farm and dom estic w orkers; and noncivilian governm ent em ployees. This series m easures personal incom e less tran s fer paym ents in co n stan t (19721 dollars. Because transfer paym ents rep resen t the largest part of p er sonal incom e not a ccru e d in p rodu ction and som e types of transfer paym ents tend to be co u n te r cyclical, th e ir rem oval from p erso n al in com e p rod u ces a series w ith greater cyclical am plitude. The cu rrent dollar series is deflated with the im plicit price deflator for pei'sonal consum ption expenditures. Personal incom e is the incom e received by p er sons from all sou rces, that is, from participation in production, from transfer paym ents from govern m ent and business and from governm ent interest, w hich is treated like a transfer paym ent. Persons consist of individuals, nonprofit institutions, pri vate noninsured welfare funds an d private trust funds. Alternatively, personal incom e is defined as the sum of w age and salary disbursem ents, o th er labor 29 FEDERAL RESERVE BANK OF ST. LOUIS incom e, p ro p rietors’ incom e w ith inventoiy valua tion and capital con su m p tion adjustm ents, rental incom e, personal interest incom e and transfer pay m ents less personal contributions to social insur ance. Transfer paym ents to p erson s are incom e pay m ents, generally in m on etary form, for w hich the recipients do not ren d er cu rren t services. They consist of business an d governm ent transfer pay m ents. Business tran sfer paym ents include liability paym ents for personal injury, co rp o rate gifts to nonprofit institutions and bad debts incu rred by con su m ers. Government transfer paym ents include paym ents u n d er the following program s: federal old age, survivors, disability an d hospital insu ran ce; supplem ental m edical in su ran ce; state unem ploy m ent insu ran ce; railroad retirem ent and u n em ploym ent in su ran ce; governm ent retirem ent; work e rs’ co m p en sation ; veterans benefits, including veterans life insu ran ce; food stam ps; black lung benefits; supplem ental security in com e; an d direct relief. Also included are governm ent paym ents to nonprofit institutions o th er than those for work u n d er research an d developm ent co n tracts. The implicit p rice deflator for personal co n sum ption expen d itures (PCE) is a cu rren t w eighted index (1972 = 100) derived by dividing cu rren t dollar PCE by co n stan t dollar PCE for each period. It is a w eighted average of the detailed p rice indexes used in the deflation of PCE w ith com p osition of the con stan t dollar PCE in each q u arter as w eights. Index o f Industrial Production This series m easures m onthly ch an ges in the physical output of the m anufacturing, mining, and gas an d electric utility industries. F o r m an u factu r ing and mining, p ro d u cts at all stages of fabrication are included. The index does not cover p rodu ction on farms o r in the co n stru ction , transportation, Digitized for 30 FRASER NOVEMBER 1985 trade and service industries. It does, however, in clude p rodu ction at plants an d shipyards ow ned and operated by the governm ent. The ind ex is co n stru cted using d ata supplied by governm ent agen cies and trade organizations, an d u ses 1977 as the base year. It is b ased on 252 series that are co m bined with value-added w eights to create the total index of industrial produ ction . Manufacturing and Trade Sales in Constant (1972) Dollars This series m easures th e m onthly volum e of sales of m anufacturing, m erch an t w holesalers an d retail establishm ents in co n stan t 1972 dollars. The series is com piled from d ata collected ea ch m on th by the Bureau of the C ensus in the shipm ents, inventories and orders survey an d in the m erch an t w holesalers and retail trade surveys. They are adju sted to benchm arks from the five-year cen su ses of m an u factures, w holesale trade, and retail trad e an d to interim annual surveys. Basic d ata on m an u factu rers’ sales are the value of their shipm ents for d om estic u se o r exp ort. Ship m ents are m easured by receip ts, billings or the value of p ro d u cts shipped (less discounts, retu rn s and allowances) an d generally exclu d e freight charges an d excise taxes. Deflated sales are co m p u ted as follows: m an u fac tu rers’ sales are deflated by industry levels (stan dard industrial classification as defined by the Bu reau of the Census) prim arily using p ro d u ce r p rice indexes com bined w ith 1977 p ro d u ct-class sh ip m en ts w eights; w holesale sales are deflated by kind of business using ap p rop riate p ro d u ce r p rice in d exes along w ith 1 9 7 7 co m m o d ity -lin e sales weights; and retail sales are deflated by kind of business using co m p o n en ts of the co n su m e r price index w ith 1972 ce n su s com m odity-line sales weights.
