Monetary Policy at a Time of Uncertainty and Tight Labor Markets
Remarks by
Jerome H. Powell
Chairman
Board of Governors of the Federal Reserve System
at
"Price and Wage-Setting in Advanced Economies,"
an ECB Forum on Central Banking
Sintra, Portugal
June 20, 2018
Nine years into an expansion that has sometimes proceeded slowly, the U.S.
economy is performing very well. Growth is meaningfully above most estimates of its
long-term trend--though admittedly, that trend is not as strong as we would like it to be.
The labor market is particularly robust, with unemployment at its lowest level since April
2000. Inflation has moved up close to our 2 percent objective, although we have yet to
see it remain near that objective on a sustained basis.
Today, most Americans who want jobs can find them. High demand for workers
should support wage growth and labor force participation--the latter a measure on which
the United States now lags most other advanced economies.1 A tight labor market may
also lead businesses to invest more in technology and training, which should support
productivity growth. And groups such as some racial and ethnic minorities that still have
higher unemployment and lower participation rates could see increasing benefits from a
tight labor market.2 In short, there is a lot to like about low unemployment.
Achieving our statutory goal of maximum employment in a context of price
stability and financial stability is both our responsibility and our challenge. Earlier in the
expansion, as the economy recovered, the need for highly accommodative monetary
policy was clear. But with unemployment low and expected to decline further, inflation
close to our objective, and the risks to the outlook roughly balanced, the case for
continued gradual increases in the federal funds rate is strong.

Current Labor Market Conditions
At 3.8 percent, the unemployment rate is below most estimates of its long-run
level, which are now clustered in the mid-4s. Many other labor market indicators also
suggest an economy near full employment. To name just a few, these indicators include
an elevated level of job vacancies. For the first time since the Labor Department began
collecting the data in 2000, there are now more job vacancies than there are people
counted as unemployed. In addition, the rate at which workers are quitting their jobs is
elevated, a sign that workers are able to find another job when they seek one. And
surveys show that businesses are finding it difficult to fill vacancies, and that households
perceive jobs as plentiful.
Some other indicators are less clear. The labor force participation rate of prime-
age workers has moved up in recent years but remains below pre-crisis levels.3 In
addition, wage growth has been moderate, consistent with low productivity growth but
also an indication that the labor market is not excessively tight.
Looking ahead, the job market is likely to strengthen further. Real gross domestic
product in the United States is now reported to have risen 2-3/4 percent over the past four
quarters, well above most estimates of its long-run trend. Expansionary fiscal policy is
expected to add to aggregate demand over the next few years. Many forecasters expect
the unemployment rate to fall into the mid-3s and to remain there for an extended period.
If that comes to pass, it will mean the lowest unemployment in the United States since the
late 1960s.

A historical comparison
Because we have so little experience with very low unemployment, it is
interesting to compare today's labor market with that earlier period. Unemployment was
below 4 percent from February 1966 through January 1970. During that time, inflation as
measured by the price index for personal consumption expenditures increased from
below 2 percent in 1965 to about 5 percent in 1970. In hindsight, unemployment is now
widely thought to have been unsustainably low at that time and to have contributed to
escalating inflation.
But how significant is this precedent for today? The U.S. economy has changed
in many ways over the past 50 years. By some estimates, the natural rate of
unemployment is substantially lower now.4 For example, the Congressional Budget
Office now estimates that the natural rate was about 5-3/4 percent (and rising) in the late
1960s, compared with 4-3/4 percent at present.5
Rising education levels do point to a decline in the natural rate since the 1960s,
because more highly educated people are less likely to be unemployed. The share of the
population with a college degree has risen from less than 15 percent in the late 1960s to
nearly 40 percent now, and the share with less than a high school degree has declined

The natural rate of unemployment is the unemployment rate over the longer term that is consistent with
low and stable inflation. It comprises both the "frictional" unemployment of people who are temporarily
between jobs or searching as they have reentered the labor force and the more "structural" unemployment
of people whose skills or physical location are not a good match for the jobs available. For more
discussion, see Janet L. Yellen (2017), "The Goals of Monetary Policy and How We Pursue Them," speech
delivered at the Commonwealth Club, San Francisco, January 18,

Contemporaneous estimates of the natural rate (or "full employment") from the late 1960s were lower
than current estimates for that period. For example, the Economic Report of the President from 1968
defined potential output as occurring when the unemployment rate is 4 percent. See Executive Office of
the President of the United States (1968), Economic Report of the President (Washington: U.S.
Government Printing Office, February), p. 61, http://www.presidency.ucsb.edu/economic_reports/1968.pdf.

from 45 percent to about 5 percent.6 Another important difference from the 1960s is that
inflation has been low and stable for an extended period, which has better anchored
inflation expectations. Today policymakers have a greater appreciation of the role
expectations play in inflation dynamics and a clearer commitment to maintaining low and
stable inflation.
Unfortunately, with the passage of a half-century and important changes in the
structure of our economy and in central bank practices, in my view the historical
comparison does not shed as much light as we might have hoped.
Questions prompted by a tight labor market
The lack of useful historical precedent leaves us with some uncertainty about the
answers to several important and challenging questions. First, estimates of the natural
rate of unemployment by Federal Open Market Committee (FOMC) participants and
others have drifted lower as unemployment has declined without much apparent reaction
from inflation. How reliable are these estimates? Natural rate estimates have always
been uncertain, and may be even more so now as inflation has become less responsive to
the unemployment rate.7 The anchoring of expectations is a welcome development and
6
Other changes in the workforce since the late 1960s seem less likely to have much affected the natural
rate of unemployment. There are many more women in the workforce now, but while women used to have
higher unemployment rates than men, that is no longer the case. And while younger workers tend to have
less stable employment patterns and higher unemployment rates than older workers, the working
population is, on net, only a little bit older now than it was in the late 1960s. (The average age of people in
the workforce declined through the 1970s as more of the baby-boom generation entered their working
years, but it increased subsequently.)

the United States, see Olivier Blanchard, Eugenio Cerutti, and Lawrence Summers (2015), "Inflation and

estimates of the natural rate, a classic reference is Douglas Staiger, James H. Stock, and Mark W. Watson

has likely played a role in flattening the Phillips curve. But a flatter Phillips curve makes
it harder to assess whether movements in inflation reflect the cyclical position of the
economy or other influences.
Second, what would be the consequences for inflation if unemployment were to
run well below the natural rate for an extended period? The flat Phillips curve suggests
that the implications for inflation might not be large, although a very tight labor market
could lead to larger, nonlinear effects. Research on this question is ambiguous, again
reflecting the limited historical experience.8 We should also remember that where
inflation expectations are well anchored, it is likely because central banks have kept
inflation under control. If central banks were instead to try to exploit the
nonresponsiveness of inflation to low unemployment and push resource utilization
significantly and persistently past sustainable levels, the public might begin to question
our commitment to low inflation, and expectations could come under upward pressure.
So far, we see no signs of this. If anything, some measures of longer-term inflation
expectations in the United States have edged lower in recent years.
Third, can persistently strong economic conditions pose financial stability risks?
Of course, strong economic conditions are a good thing! Such conditions can make the
financial system better able to absorb shocks through strong balance sheets and investor
confidence. But we have often seen confidence become overconfidence and lead to
excessive borrowing and risk-taking, leaving the financial system more vulnerable.

Indeed, the fact that the two most recent U.S. recessions stemmed principally from
financial imbalances, not high inflation, highlights the importance of closely monitoring
financial conditions. Today I see U.S. financial stability vulnerabilities as moderate and
broadly in line with their long-run averages. While some asset prices are high by
historical standards, I do not see broad signs of excessive borrowing or leverage. In
addition, banks have far greater levels of capital and liquidity than before the crisis.
Fourth, while persistently strong economic conditions can pose risks to inflation
and perhaps financial stability, we can also ask whether there may be lasting benefits. As
I mentioned, a tight labor market could draw more people into the labor force. In fact, as
the labor market has tightened, more workers have been moving back to work and off
disability rolls.9 There could also be benefits to productivity and potential growth. All
told, though, the persistence of any such "positive hysteresis" benefits is uncertain, since,
again, the historical evidence is sparse and inconclusive.
Conclusion
As is often the case, in the current environment, significant uncertainty attends the
process of making monetary policy. Today, with the economy strong and risks to the
outlook balanced, the case for continued gradual increases in the federal funds rate
remains strong and broadly supported among FOMC participants.
