Jeffrey M. Lacker
President, Federal Reserve Bank of Richmond
I am pleased to be with you tonight to discuss my views on the outlook for inflation.1 In
its most recent statements, the Federal Open Market Committee has identified “the risk
that inflation will fail to moderate as expected” as its “predominant policy concern.” This
places current inflation and the inflation outlook squarely at center stage in thinking
about the economy and monetary policy. So in my remarks tonight, I will take a closer
look at inflation’s recent behavior and the prospects for its future behavior. In doing so,
I’ll place particular emphasis on what we’ve learned in recent years about inflation
dynamics, particularly the interplay between real activity and inflation expectations. As
always, these remarks should be taken as my own personal views, and not necessarily
shared by any of my colleagues in the Federal Reserve.
Recent Inflation
To put the current situation in context, recall that under Chairman Paul Volcker, the
FOMC brought inflation down to below 4 percent in the mid-1980s. (Throughout my
remarks tonight, unless otherwise noted, I will be referring to inflation measured by the
12-month growth rate in the monthly price index for core personal consumption
expenditures.) Under Chairman Alan Greenspan, core inflation fluctuated between 3½
percent and 5 percent until 1992, but fell to near 2 percent in 1994, and below 2 percent
in March 1996. Inflation then remained between 1 percent and 2 percent more or less
continuously until April 2004. The exception was several months during the second half
of 2001 as the economy slipped into a recession.2 From 1996 through 2003, a period of
eight years, core PCE inflation averaged 1.6 percent, and was between 1 and 2 percent 90
percent of the time.
In early 2003, inflation fell, and for some months inflation was reported to be below 1
percent at an annual rate.3 This led to concern about the possibility of excessive
disinflation, and in response, the FOMC statement at the May meeting cited the risk of
“an unwelcome substantial fall in inflation,” and at the June 2003 meeting, the FOMC
reduced the target federal funds rate to 1 percent. While the Committee had not then, and
has not since, established an explicit numerical target range for inflation, the May 2003
statement was taken to many observers as establishing an implicit lower bound on the
range of inflation rates the Committee would find acceptable.4
Core inflation has increased since 2003. From a low of 1.3 percent for the 12 months
ending in September 2003, it rose to more than 2 percent in April 2004, and has
fluctuated between 2 percent and 2.4 percent ever since. Monthly readings have exhibited
wider swings in recent months, and 12-month inflation has fluctuated accordingly, falling
to 2.1 percent in November but then rising 2.4 percent again for February. (Translating
the April CPI report suggests that core PCE inflation will step up to 2.2 percent.) Given
these repeated swings, it is not surprising that it is difficult to pick out a definite trend,
and in fact, no statistically significant moderating trend has emerged yet, an issue I will
return to later in my talk. About all one can say with confidence is that core inflation is
now fluctuating around 2¼ percent.
Chairman Ben Bernanke, in his March 28 testimony to the Joint Economic Committee,
said about core inflation that “recent readings have been somewhat elevated and the level
of core inflation remains uncomfortably high.” In addition, I and several other FOMC
participants have expressed dissatisfaction with the current level of inflation. Even
though, as I noted earlier, the Committee has not established an explicit numerical
objective or range for inflation, some observers have taken recent comments as indicating
an upper bound on the range of desired inflation rates, analogous to the way the
Committee’s May 2003 statement was taken as marking a lower bound.
The central question, then, regarding the outlook for inflation is whether core inflation
will “moderate” to an acceptable rate in coming quarters. Some forecasters are expecting
inflation to decline this year and next, and many of them link this decline to the
expectation that real growth has been weak and is expected to remain below trend over
the next few quarters. The relationship between real activity and the inflation outlook,
which I will discuss in more detail later on, is important enough to warrant a look at
selected components of final demand.
Real Activity
Housing construction is the component of aggregate output that has understandably
attracted the most attention lately. The recent weakness followed a decade-long period of
sustained growth in housing activity, which was driven by favorable fundamental factors,
such as improving prospects for real income growth, unusually low inflation-adjusted
mortgage interest rates, increasing population, and the favorable tax treatment of owner-
occupied housing. By the end of 2005, though, demand appeared to have been largely
satiated in most local markets. Since then, although some markets continue to show
steady growth, many markets have seen sharp reductions in construction and homes sales,
and a slowdown in housing price appreciation. Indeed, in some locations prices have
begun to decline. The fact that housing data are typically somewhat noisier in winter
months is making it difficult to gauge whether housing demand has reached bottom as
yet. Even if it has, however, the need to work off an overhang of new homes inventories
is likely to depress new construction spending for several months to come.
One prominent feature of the expansion of housing activity was a dramatic advance in
lending to subprime borrowers, and the recent increase in delinquencies and defaults in
this sector has raised concerns. This is not the time for a thorough review of the subprime
mortgage market – that would be a separate speech.5 All things considered, the
macroeconomic effects of recent developments in the subprime market are likely to be
relatively limited, and I do not expect any significant spillovers to the rest of the
economy.
2
Business investment spending has been an impressive source of strength over much of
this expansion. Real spending on equipment and software increased at a healthy 8.7
percent annual rate from the first quarter of 2003 to the first quarter of 2006. Spending on
structures picked up at the end of 2005, increasing 14 percent in the four quarters ending
in Q3. Business investment faltered late last year though, with weaker sales of autos and
construction materials apparently playing important roles. Most of the fundamentals for
business investment are still quite positive, however; profitability is high, the cost of
capital is fairly low, and funds for new investment are readily available on favorable
terms. Thus I expect investment to gain momentum this year, and we are already seeing
some favorable signs.
Growth in consumer spending has been another source of strength in this economic
expansion. That growth has been underpinned by solid real income growth during the
recovery and favorable prospects for future income growth. Many observers
hypothesized that the drag from weakening housing markets would spill over and dampen
consumer spending. That hasn’t happened. Last year, real consumer spending rose 3.6
percent, and in the first quarter it increased at a 3.8 percent annual rate.
Some observers have questioned the outlook for consumer spending, often citing
statistics that lead them to believe that consumer debt is too high or consumer saving is
too low. I won’t argue with the data – by the usual measures saving is quite low, with the
widely cited personal saving rate clocking in at negative 1 percent for the first quarter.
But keep in mind that the personal saving rate has been on a downward trend from about
10 percent in the early 1980s to about minus 1 percent now. A number of forces could
potentially be at play here, including, for example, the significant credit market
innovations that have taken place over that period.6 I understand how historical averages
can exert a gravitational pull on the forecasts of variables like the saving rate, and I don’t
believe the downward trend is likely to persist indefinitely. But having said that, it’s not
obvious to me why we should expect that long-term trend to reverse itself beginning
precisely next quarter.
An alternative perspective on savings and consumption is that the strong recent growth in
household spending indicates optimism about future income prospects, rather than any
fundamental recklessness. The labor market is reasonably tight, with the unemployment
rate at 4.5 percent. Earnings are growing at about a 4 percent rate. The working age
population is growing at a 0.9 percent annual rate, and payroll employment has grown
significantly more rapidly, at a 1.6 percent rate for the last few years. While employment
growth won’t be above average forever, prospects for real income growth look pretty
solid. Moreover, household net worth is up to 5¾ years of disposable personal income,
and has been rising during this recovery, which suggests that savings, properly measured,
might not be so low after all. As always, real wage growth will tend to track gains in
labor productivity, and while productivity growth was fairly strong for the first several
years of this decade, the recent slowdown is a negative risk for consumer spending. On
balance, though, I expect consumer spending to remain reasonably healthy.
3
Putting this all together, I expect overall growth to come in below trend in the first half of
this year, but to return to trend by the end of the year, based on my expectation that the
housing market is likely to find a bottom some time this year and no longer be a drag on
top line growth, business investment will pick up, and consumer spending will remain
healthy.
The Phillips Curve
As I mentioned earlier, many commentators base their belief that inflation will moderate
on their belief that output growth will be below trend for the next few quarters. This
connection is based on a popular – though I will argue incomplete and potentially
misleading – understanding of the relationship between inflation and real economic
activity. This relationship is usually described by the “Phillips curve,” which typically
shows an inverse relationship between inflation and unemployment or the “output gap.”7
One way of thinking about the Phillips curve is to see it as describing a set of options
facing policy makers – as if to say, “You can have less inflation with more
unemployment or less unemployment with more inflation.” This characterization is very
much in keeping with one of the earliest expositions of the Phillips curve as a tool for
economic analysis and policy. In 1960, Paul Samuelson and Robert Solow estimated a
Phillips curve for U.S. data, following A.W. Phillips’ earlier exercise for the United
Kingdom, and indicated that this curve described the set of options available to policy
makers “in the years immediately ahead.”
This traditional view of the Phillips curve sees the relationship between the real growth
and the outlook for inflation as a structural part of the economy, that is, as invariant to
alternative approaches to policymaking. Under this view, growth below trend causes a
growing amount of “slack” in the economy, which in turn eases price pressures. And
conversely, of course, price pressures build up when aggregate demand runs ahead of the
economy’s capacity for growth, making labor and commodity markets tight. This view
sees policymakers as controlling inflation by using interest rates to engineer the
appropriate amount of slack.
But this view of the Phillips curve is out of date and can be seriously misleading. As a
purely empirical relationship, it broke down entirely during the 1970s, when inflation and
unemployment were both simultaneously elevated. Modern monetary economics now
understands the relationship between inflation and real activity as resulting from the
decentralized price- and wage-setting decisions of firms and workers facing frictions that
make very frequent price re-adjustments suboptimal. Firms set prices based on their
expectations regarding the marginal cost of production and the rate at which overall
nominal demand will change over their planning horizon. Aggregating across sellers, one
finds that the current overall price level, and thus current inflation, depends on expected
future inflation and real marginal cost. Under certain assumptions, real marginal cost
moves one-for-one with a measure of aggregate economic activity such as the output gap
or the unemployment rate.8
4
The result is a version of the Phillips curve in which current inflation depends on
expected future inflation and an indicator of current economic activity, such as
unemployment or the “output gap.” But to state it this way – with inflation depending on
a real variable – is entirely arbitrary. One could just as well write the relationship the
other way and say that unemployment, for example, depends on inflation and expected
inflation. In fact, inflation and real economic activity are the joint outcome of
decentralized decisions made by participants in the economy about demand, supply,
prices and wages. So it is just as correct (or rather incorrect) to say below-trend growth
will drive inflation down, as it is to say that falling inflation will keep growth below
trend. Because inflation ultimately depends on the actions of the central bank, those
decentralized decisions will depend on past, present and expected future central bank
policy choices. Thus, it is central banks, not the labor market, that drive inflation down.
The behavior of inflation expectations is vitally important to a central bank that is
attempting to reduce inflation. If inflation expectations are low and consistent with the
reduction in inflation that the central bank wishes to bring about, it will be important to
assure that they do not drift higher during the disinflation process. If inflation
expectations have become elevated, a sustained reduction in inflation will require
bringing inflation expectations down as well.
Inflation expectations embody assumptions – either explicit or implicit – about how the
central bank is going to conduct monetary policy in the future. One possibility is that
expectations are the result of past experience – that people simply extrapolate the recent
behavior of inflation into the future. Statistically, this approach to expectations may work
reasonably well for people most of the time, especially if the fundamental behavior of the
central bank is not changing much. People taking this approach would tend to not adjust
their expectations for future inflation until they saw movements in actual inflation. In this
case, a successful disinflation that brings down both actual and expected inflation could
be protracted and costly. With inflation expectations tied down by past experience, the
remaining mechanism for bringing down inflation is just the mechanism of the original
Phillips curve – an increase in real interest rates that slows aggregate demand and reduces
actual inflation.
Alternatively, people may take a more forward-looking approach. They may believe that
current inflation has deviated temporarily from its long-run trend, and so they may
discount recent observations. Moreover, they take into account that inflation will behave
differently in the future if the behavior of the central bank changes. This is likely to be
particularly important if the central bank communicates convincingly its intention to
behave differently. For example, in many countries inflation expectations seemed to shift
when the central bank adopted inflation targeting. Public understanding of the central
bank’s long-run goals and of how the central bank would respond to various potential
economic disturbances helps anchor inflation expectations.
Inflation Expectations
5
If inflation expectations are a key determinant of the current behavior of inflation, then
what do we know about the recent behavior of inflation expectations? There are a variety
of indicators and as you might expect, none of them is perfect. Survey measures have the
longest track record. The Philadelphia Fed compiles and publishes the Survey of
Professional Forecasters every quarter. Their most recent compilation, published just last
week, reports a mean expectation for core PCE inflation of 2.1 percent through the end of
2009. The average forecast for CPI inflation from the Blue Chip survey is 2.4 percent for
core Consumer Price Index in 2007, and 2.3 percent in 2008, which based on an assumed
gap of four-tenths between PCE and CPI inflation translates into 2.0 percent and 1.9
percent, respectively, a bit lower than the Philadelphia survey. Consumer surveys, in
contrast, yield much higher figures. Among respondents to the Reuters - University of
Michigan survey, the median expected inflation over the next year is 3.2 percent and the
median expected inflation over the next ten years is 3.1 percent. Economists typically
discount data from such consumer surveys in which respondents have little or no
economic incentive to forecast well. Professional forecasters presumably perceive a
pecuniary benefit to having a documented record of accuracy.
Measures of expected inflation can be derived from the spreads between indexed and
non-indexed U.S. Treasury securities – the so-called TIPS spread. The improvement in
recent years in the depth and liquidity of the market for indexed securities provides at
least some confidence that such measures reflect a reasonable aggregation of market
participants’ inflation expectations. The implied expectation of CPI inflation over the
next five years was around 1½ percent in early 2003, rose to near 2½ percent in 2004,
and has been trading around 2.3 percent in recent weeks. Taking off four-tenths for the
average PCE-CPI spread, this translates to around 1.9 percent. Expectations for five-year
inflation beginning five years from now have been running recently between 2.4 percent
and 2.5 percent.
Another place to look for evidence on inflation trends is the growth in labor
compensation. Hourly compensation in the nonfarm business sector accelerated from
under 4 percent in 2005 to 5 percent in 2006. This is consistent with the broad
acceleration in average hourly earnings shown in the Employment Report, and the
upswing in the Employment Cost Index. Inflation-adjusted compensation gains should
(and generally do) track labor productivity gains fairly closely. This is algebraically
equivalent to saying that the markup over unit labor costs should be fairly constant. If so,
the growth in unit labor costs should provide a gauge of expected inflation trends, the
idea being that workers and firms set current wages based on their near-term expectations
for real productivity gains and inflation. Productivity growth was relatively high early in
this decade, but has decelerated recently and averaged 1.6 percent last year. As a result,
unit labor costs have accelerated and have averaged 2.4 percent over the last two years.
The markup has been relatively steady at an elevated level over the two years, which with
rising unit labor costs is consistent with the rise in inflation we’ve seen.
If unit labor costs continue to advance at recent rates, either inflation will keep pace with
unit labor costs, or the increase in labor costs will be absorbed by firms lowering their
markups. It is true that the markup implied by the productivity and unit labor cost
6
numbers have been high by historical standards, which accords well with the recent
strength in business profits, but our understanding of aggregate movements in the markup
is limited. The markup has tended to revert to its mean, but it can deviate for long
stretches of time. So while it is possible that the markup might fall to offset a rise in unit
labor costs, if we don’t know why the markup is elevated now, its hard to have much
confidence in a forecast that it is going to come to our rescue just in the nick of time. If
the markup remains relatively high, and unit labor costs continue to advance at or above 2
percent, then we are likely to see inflation continue at about 2 percent.
Corroborating evidence on inflation expectations is provided by recent work by James
Stock and Mark Watson.9 They estimate a model of postwar U.S. inflation that allows
them to decompose inflation into a “trend” and “transitory” components, each with their
own time-varying volatility. The time-varying volatility feature allows for changes over
time in the portion of the variability in inflation that is due to long-lasting swings in trend
inflation, as we saw in the Great Inflation of the 1970s, as opposed to short-run transitory
movements in inflation. They find that the variability in the trend component of inflation
has fallen dramatically since the 1970s, consistent with other research that has
documented a fall in the “persistence” of inflation since then.10
Stock and Watson’s methodology implies that the best forecast for future inflation is the
current estimated value of the trend component, which they put at 2.1 percent (for core
PCE inflation) as of the first quarter of 2007. This measure of trend inflation has been
above 2 since the fourth quarter of 2004, and peaked at 2.2 percent in the second quarter
of 2006. Interestingly, their measure of trend was between 1.3 percent and 1.8 percent for
over eight straight years from 1996 to 2003.
The Stock and Watson framework provides a natural way to assess whether any
moderation in core inflation is evident yet. Their measure of trend inflation fell by 6 basis
points from the peak (2.17 percent) in the second quarter of last year to the first quarter of
2007 (2.11 percent). Given the shape of the probability distribution around their
estimates, this decline does not appear to be statistically significant.
Outlook
A variety of expectations measures then, point to expectations for core PCE inflation of
about 2 percent right now. What does this imply about the outlook for actual inflation,
which is now running at about 2¼ percent? The current level of inflation expectations is
likely to exert a gravitational pull on actual inflation, if monetary policy actions are not
inconsistent with those expectations and no concerted effort is made to shift expectations.
Policy actions at variance with those expectations – for example, significant easing at a
time of elevated or rising inflation – would likely call those expectations into question
and lead to a change in assessments regarding future inflation. But as long as policy
actions appear to be plausibly consistent with movement toward 2 percent inflation and
nothing else acts to alter inflation expectations, that’s likely to be the best forecast of
where inflation is headed.
7
Could inflation fall below 2 percent, say to 1½ percent? That depends. Without a prompt
fall in inflation expectations, a reduction in inflation below 2 percent is likely to be
temporary and hard to sustain. With expectations left alone, the remaining mechanism for
bringing down inflation is the traditional Phillips curve mechanism, that is, an increase in
real interest rates that slows aggregate demand and reduces both inflation and real
activity. If expectations do not adapt to lower inflation, a sustained reduction in
employment and output would be required to push inflation down.
The prospects for bringing inflation down below 2 percent thus hinge on the extent to
which a reduction in inflation expectations can be brought about. How difficult would
that be? Using changes in the target interest rate alone, the process is likely to be difficult
and time-consuming. Costly reductions in real incomes and employment would be
required until inflation expectations adapt. Without information suggesting a change in
the pattern of monetary policy conduct or clarifying the intentions of policymakers,
market participants could well interpret policy moves as the continued implementation of
past strategy.
One natural approach to bringing inflation expectations down more expeditiously, should
that be the desire, would be a strategy of clear communications about policymakers’
intentions. Just how responsive would inflation expectations be to such communications?
General conclusions are unlikely, because the results will depend on the nature of
communications, the nature of the accompanying actions, and the context in which they
are received. There are many historical examples of significant shifts in monetary policy
expectations; examples include the fiscal reforms accompanying the ends of
hyperinflations, the governance changes accompanying the adoption of explicit inflation
objectives in other countries, and the operational regime shift adopted by the Volcker-led
FOMC in 1979.
These examples involved fairly dramatic and sizable shifts in the conduct of monetary
policy, however. Shifting inflation expectations from 2 percent down to 1.5 percent or 1
percent represents a far smaller change in policy, and thus ought to be less difficult. In
fact, exactly the opposite transition was made three years ago. As I noted earlier, core
inflation was between 1 and 2 percent from 1996 through early 2004, and since early
2004 core inflation has been between 2 and 2½ percent. Inflation expectations seem to
have shifted up accordingly; for example the TIPS spread was around 1½ percent in
2003. The fact that core inflation so recently spent eight years between 1 and 2 percent
suggests that convincing the public that we were returning to such a period would not be
that difficult, especially in light of the fact that the Committee did not, during that earlier
period, announce an intention to keep core inflation within that band.
In many recent instances, FOMC actions or statements appear to have induced
simultaneous short-run movements in market participants’ expectations regarding the
path of the federal funds rate and inflation. For example, following the heavy hurricane
season of 2005, energy prices surged, policy expectations initially softened, and measures
of inflation expectations rose. Shortly thereafter, core inflation also increased.
Expectations were subsequently realigned after a number of speeches and statements by
8
FOMC members, but similar sequences occurred in early 2004 and the spring of 2006. A
similar episode occurred in the spring of 2006 in response to another round of energy
price increases. Inflation expectations rose, but were subsequently tamped down by
Committee member communications. In both cases, the movement in inflation
expectations was relatively contained, but these short-run spikes suggest a pliability of
inflation expectations in the current environment.
The outlook for inflation, then, is to an important extent contingent on policymakers’
assessments of their ability to influence the evolution of inflation expectations. Such
assessments will inevitably be inexact. Although there may be no precise historical
analogs for communication and actions to reduce inflation expectations in circumstances
like the present, my sense is that clear communications accompanied by consistent
actions could bring about a relatively prompt and low-cost reduction in inflation.
But in any event, there is little disagreement about the central importance of inflation
expectations for the conduct of monetary policy. Inflation expectations are an outcome of
monetary policy, not an autonomous help or hindrance, and central banks are as
responsible for the behavior of inflation expectations as they are for the behavior of
inflation.
Thank you.
