Domestic Macroeconomic Developments: Past, Present, and Future
Thank you for inviting me to the Bay Area Council 2001 Outlook Conference. As always,
the views I will be expressing are my own and are not necessarily shared by other members
of the Board of Governors or of the Federal Open Market Committee.
Before I discuss the current economic environment and recent monetary policy actions, let
me set the stage with a brief review of the extraordinary performance of the U.S. economy
in the second half of the 1990s. From 1995 to 1999, real gross domestic product grew, on
average, about 4 percent per year. This pace was significantly above that in the previous five
years, and you would have to go back to the 1960s to find even closely comparable periods
of consistently robust economic expansion. In this environment, the unemployment rate fell
to 4 percent, and the underlying rate of price inflation slowed, on net, despite very high rates
of resource utilization. Even the most optimistic of forecasters could not have anticipated
such a favorable confluence of economic events.
Productivity Growth and Cost Reductions
So, how did this confluence of positive events come about? As a policymaker, I’d like to
think that well-executed monetary and fiscal policies--each focused importantly on their
respective long-run goals of achieving price stability and reining in deficit spending-- played
some role in creating economic conditions that fostered noninflationary economic growth.
Our economy has also benefited from past actions by the government to deregulate
industries. The removal of unnecessary government regulation started more than twenty
years ago, during the Administration of President Ford, and gathered momentum during the
Carter years. It has altered the business landscape by allowing, indeed forcing, businesses to
focus more clearly on a more competitive marketplace with fewer constraints and increased
flexibility.
But the dominant force of late appears to have been a significant increase in the rate of
productivity growth: Output per hour in the nonfarm business sector--a conventional
measure of productivity--increased at an annual rate of almost 3 percent between 1995 and
1999, well above the pace earlier in the decade. Cyclical forces such as the inability of
businesses to add to their payrolls as rapidly as they would have liked in response to the rise
in demand probably played some role in these productivity gains. But probably more
important, I suspect, were longer-term, structural changes arising from the boom in capital
spending and the revolution in information technology. Let me turn to the evidence on this
point.
Technology Change and Productivity Growth
Bob Solow--the MIT economist who won the Nobel Prize in economics for his work on the

theory of economic growth--once quipped that you can see computers everywhere except in
the productivity statistics. A few years ago that situation began to change, and we now have
strong evidence that the faster productivity growth our economy has experienced is, in fact,
due partly to newer technologies.
Research by Federal Reserve Board economists Steve Oliner and Dan Sichel sheds some
light on the sources of this faster productivity growth. The high (and rising) levels of
business investment raised the amount of capital per worker and thereby boosted
productivity. About 1/2 percentage point of the increase in productivity growth over the
1995-99 period can be attributed to this so-called “capital deepening,” most of which
reflected greater spending by businesses on computers, software, and communications
equipment. Another 1/2 percentage point of the pickup in productivity growth reflected
technological innovations in the actual production of computer hardware and
semiconductors as well as better management--perhaps assisted by these high-tech
investments--of the nation’s capital and labor resources. Oliner and Sichel estimate that the
consolidated influences of high-tech investments account for about two-thirds of the
acceleration in productivity since 1995. This research supports the view that fundamental
changes are under way in our economy.
What’s So Special about this Capital?
That trend productivity has picked up and that high-tech investments are the source of the
acceleration are important facts, but by now they are not new observations. Perhaps at this
stage it would be useful to explore in greater detail this positive “shock” to the ability of our
economy to produce goods and services. What is so special about computers and other
information technologies that they can have such a strong influence on our economy?
Let me highlight three special characteristics of high-tech equipment. First, computers and
communications equipment depreciate at a very rapid pace. The current best estimate is that
computers probably depreciate about 30 percent annually, although that estimate might be
low, while other equipment probably depreciates at a rate of less than 15 percent annually.
Therefore, computers are retired, on average, after three years, and the useful life for other
equipment is about seven years. Firms must invest in computers at a faster rate than that for
other forms of capital just to maintain a given level of the capital stock. The rapid
replacement of high-tech capital means that technological progress becomes “embodied” in
the capital stock at a faster rate than is the case for longer-lived assets.
The second feature of high-tech equipment that sets it apart from other classes of capital is
the sensitivity of its demand to fluctuations in the cost of capital. Economists have debated
for decades about the magnitude of cost-of-capital effects on traditional capital goods. A
past consensus was that the cost-of-capital effect was small and very difficult to identify
empirically. A somewhat different conclusion has arisen lately when the same basic models
of investment are applied to spending on computers alone. The latest research suggests that
computers are quite sensitive to movements in the cost of capital. The combination of an
apparently high price elasticity and a rapid decline in relative computer prices -- 20 percent
per year over the past decade -- likely led to the boom in high-tech investment.
A third characteristic of high-tech investment is the magnitude of “external” or “spillover”
effects that it generates. High-tech equipment generates benefits not only to the owner of the
machine but to other agents in the economy as well. I am thinking in particular about
so-called network effects--that is, linking computers together makes possible larger
productivity gains than do computers operated as stand-alone units. Although difficult to

measure, such network effects certainly have stimulated the demand for high-tech
equipment and have helped to speed up the dispersion of new technologies.
Supporting Structural Changes
The technological changes inspired by investments in computers have enhanced the ability
of businesses to reduce their operating expenses. In many industries, investments in
information technologies have helped firms to cut back on the volume of inventories that
they hold as a precaution against glitches in their supply chain or as a hedge against
unexpected increases in aggregate demand. Product development costs have probably also
been reduced through the use of better computer hardware and software, and new
communications technologies have increased the speed with which firms can share
information--both internally and with their customers and suppliers.
This is the intersection of macroeconomics and management. Many business observers now
believe that these newer technologies are not only reducing the cost of transforming inputs
into outputs but also decreasing “interaction costs,” the costs incurred in getting different
people and companies to work together to exchange goods and services. Obviously, the line
between “transformation” and “interaction” is not clear, but consultants who have studied
this topic believe that these interaction costs account for 55 percent of all labor costs, with
some industries, such as financial services, estimated to have interaction costs as high as 70
percent of labor costs. I cannot verify these numbers, but the general concept seems useful.
Largely as a result of the increase in productivity in the recent past, we have experienced a
remarkable stability in unit labor costs. During the past five and a half years, unit labor costs
for nonfinancial corporations, which are the most accurately measured, increased an annual
average of 0.2 percent. This compares quite favorably with the experience in the preceding
ten years of a 2.2 percent annual rate of increase. If in fact “interactions” account for 55
percent of labor costs, this relatively flat trend in unit labor costs is consistent with the
concept that the newer technologies are allowing easier, less labor-intensive, interactions.
Importantly, given the high rate of depreciation and the steep declines in costs of high-tech
equipment, these savings in unit labor costs are not being undermined by offsetting increases
in unit nonlabor costs.
Moreover, given intense competition and the resultant lack of pricing “leverage,” ongoing
programs to reduce costs have become a key part of corporate strategies to maintain or
improve profit margins. The focus on cost reduction has worked to head off the development
of inflationary pressures in this expansion.
The Macroeconomic Implications of Faster Productivity Growth
Theory teaches us that the step-up in the growth rate of technological change certainly has
important implications for economic activity and inflation. The main reason policymakers
and economists are interested in the growth rate of productivity is that it helps us to
understand the economy’s potential to supply goods and services. The effects on the
economy’s ability to produce goods and services are clear, but theory predicts that a higher
level of productivity growth would also affect the demand for goods and services. The most
immediate effects would be on capital investment, as we have seen. Businesses recognize
the new technological possibilities, and capital spending accelerates to take advantage of the
new profit opportunities.
The employment and income generated by business spending on capital goods boosts
consumer outlays and sets off another round of investment spending. Through this process,
an innovation on the supply side of the economy generates a comparable increase in

aggregate demand.
It is important to emphasize that higher productivity growth translates into higher real
income growth for employees. This added income is seen most clearly in the higher wages
paid to that growing number of workers whose cash compensation is tied to company
performance either directly or through stock options. But real incomes should increase even
for workers whose compensation is not directly linked to company performance, as
profitable business opportunities bolster the demand for scarce labor.
Theory also teaches that the increase in the rate of return on capital--even if generated by a
rise in the growth rate of technical change--ultimately requires an increase in real market
interest rates. All else equal, market interest rates must rise in order to maintain equilibrium
between the higher demand for investment funds and the supply of investment funds.
This somewhat abstract description of the effects of a step-up in the growth rate of technical
change bears a striking resemblance to the developments of recent years in labor markets,
prices of goods and services, capital investments, and fixed-income markets. But there’s still
an element missing: the stock market. A higher rate of technical change that raises the
productivity and hence the profitability of capital should elevate the value of equities. Since
equity prices reflect market expectations of future cash flow and dividends, any adjustment
in profit expectations can and does lead to a resetting of equity prices. Are stocks today
overvalued, correctly valued, or undervalued? I certainly do not know, and I am not aware
of anyone who does. As a result, I believe that it would be unwise--and indeed
impossible--for the Federal Reserve to target specific levels of valuations in equity markets.
However, equity markets obviously do have spillover effects on the real economy and, thus,
need to be considered in assessing the aggregate balance of supply and demand. Given the
efficiency and forward-looking nature of financial markets, even expected future technical
innovations will have an immediate effect on equity valuations. Equity values, in turn, can
influence consumer behavior. As you know, economists often speak of the "wealth effect,"
and econometric modeling indicates that consumers eventually tend to raise the level of their
spending by 2 to 5 cents for every incremental dollar of wealth. As a consequence, equity
valuations can have a noticeable effect on consumption and on macroeconomic
performance. To put a rough number on these influences, simulations by the Board staff
using our econometric model of the economy suggest that wealth generated in the equity
markets over the past four years added about 1 percentage point to the growth rate of real
GDP.
Of late, equity markets have given up some of their gains. However, economists who have
studied the topic generally think that the consumption effect of a change in wealth generated
by the stock market begins to build in the first year and may take two to three years to be
fully felt.
Additionally, equity markets are a source of investment capital, and valuations in the stock
market are one determinant of the cost of capital for businesses. External financing
conditions, including equity valuations, are important because recent investments have
increasingly been financed from external sources. External funds raised now account for
about 20 percent of nominal capital expenditures--close to the highs of the past two decades.
The Year 2000: A Period of Transition
Productivity-led growth continued through the first half of 2000, with real GDP racing ahead
at a breakneck 5-1/4 percent annual rate. The growth of aggregate demand was clearly

outpacing even the most optimistic projections for the growth of potential supply, and the
dangers of an increase in inflation pressures were higher. In order to promote better balance
between aggregate demand and potential supply and to contain inflationary pressures, the
Federal Open Market Committee took additional firming actions, raising the benchmark
federal funds rate 1 percentage point between February and May. Even with these increases,
the Committee felt that the balance of risks to the economic outlook still was tipped toward
greater inflation.
Signs of adjustment to a more sustainable level of growth of aggregate demand began to
emerge over the course of the summer. But with no evidence either of a significant
deterioration in price trends or a serious softening in economic activity, the FOMC entered a
period of watchful waiting. As you know, monetary policy works with long and variable lags,
and the Committee believed it appropriate to monitor how its earlier actions were affecting
the economy before taking additional steps. As the second half of the year wore on, the data
confirmed that a slowdown was under way. But for a while its extent and likely duration
were still open questions. By the time of the November meeting of the FOMC, the statistical
evidence and developments in financial markets suggested that the growth of aggregate
demand had slowed to a more sustainable pace that might even be a bit below the growth
rate of the economy’s potential to produce. But with the labor markets quite tight and energy
prices rising, the Committee still saw a continuing risk of heightened inflation.
Economic conditions changed dramatically late in the year, though. By the December
meeting, the “hard” statistical data on economic expansion, which are available with a lag,
showed some signs of weakness, but aggregate economic activity still appeared to be
expanding moderately in the fourth quarter. In contrast, other, anecdotal indicators turned
decidedly more bearish. For example, warnings of slower sales and earnings growth resulted
in substantial markdowns in the valuations of many leading high-tech companies, and
consumer confidence swooned in December. Were these the signs of the inevitable “bumps
in the road” that occur during a period of transition from rapid growth to a more sustainable
pace of expansion, or were they the early warning signs of a more serious slackening in
demand? The FOMC wrestled with this issue at its December meeting. The risks clearly had
shifted toward a period of subpar growth, but as of the middle of December, the evidence in
hand did not appear sufficient to justify a rate cut.
Following the December meeting of the FOMC, Committee members remained on “high
alert” for signs of additional slowing in the pace of economic activity. As 2001 began,
evidence accumulated that sales and production were weakening. The National Association
of Purchasing Managers report suggested widespread softness among manufacturers. Auto
sales and production were taking a hit. Revisions to the data on orders and shipments of
nondefense capital goods provided hard evidence of a slowdown in business spending on
high-tech capital goods, and more companies announced disappointing sales and earnings.
Initial claims for unemployment insurance moved up further at the end of December, and
layoff announcements increased. The reports of consumer spending at year-end were
disappointing.
In light of these factors, the FOMC acted on January 3 to cut the federal funds rate 50 basis
points. Taking a policy action between meetings surprised some observers, and some have
asked, “What does the Fed know that we don't?” The answer to this question now, as in
nearly every situation in which we change policy, is--"very little, if anything." Although I
generally favor making policy decisions at our regularly scheduled meeting, we must remain
flexible and be prepared to respond quickly and firmly to developments that deviate

significantly from our expectations.
2001 Outlook
Although some fog always surrounds the outlook, there is more than the usual amount of
uncertainty at this juncture about the economic future. Private sector forecasters have been
marking down their forecasts in response to incoming data, and most now fall somewhere
between 2 and 3 percent for real GDP growth this year. Clearly, demand has weakened
faster than most businesses anticipated, and inventories have become uncomfortably high in
some sectors. But businesses are moving fast to adjust levels of production. And final
demand should be supported by the lower interest rates put in place by the financial markets
and the Federal Reserve. Consequently, I would expect a period of notable weakness early
in 2001, followed by a pickup in activity. Despite the sharp correction in “new economy”
stock prices, I believe that the underlying technical advances I discussed earlier in this talk
will continue and will provide considerable support over time for business and consumer
spending.
In its most recent announcement, the FOMC indicated that risks remain weighted toward
economic weakness. While the scenario I outlined seems the most likely to occur, I am not
sure what level of interest rates will be associated with it. This depends on a number of
developments, including the evolution of financial markets and investor appetite for risk.
Conclusion
Obviously the stance of monetary policy will play an important role in shaping the eventual
outcome. In recent weeks the Committee’s outlook changed rapidly as a result of incoming
data and anecdotal reports, demonstrating the importance of our constant and intense
scrutiny of the economy. The Federal Reserve will continue to analyze the incoming
information carefully and will act prudently and forcefully to provide the monetary and
financial conditions that will foster price stability and promote sustainable growth in output.
