*I appreciate comments provided by my colleagues at the Federal
Reserve Bank of St. Louis, especially Howard Wall, Research Officer.
I take full responsibility for errors. The views expressed are mine
and do not necessarily reflect official positions of the Federal
Reserve System
There was a time when the Federal Reserve encouraged
a public perception of the mystique of policymaking. That is not
the Fed's view today, but my reading of press commentary suggests
that the old perception has not disappeared. There is, however,
a difference. Today, rather than referring to the mystique of policy,
people are more likely to refer to policy as "obtuse,"
"incomprehensible" or "deliberately confusing."
Chairman Greenspan sometimes takes delight in saying such things
as "Senator, if you understand what I just said I must have
made a mistake."
Although mystique has turned into fodder for cartoonists, and
it is healthy that we smile at ourselves from time to time, there
is a serious issue involved. Beginning about 35 years ago, developments
in macroeconomic theory began to make clear that the performance
of the economy depends critically on market expectations about how
economic policymakers will act in the future. As our understanding
of these issues has deepened, it has become clear that one of the
key dimensions of a successful monetary policy is that the policymakers
need to have well-defined goals and a clear plan as to how they
will go about achieving the goals. Both of these need to be understood
in the markets; otherwise, the economy faces the equivalent of a
broken play in football, where some members of a team think one
play is being run and others think another play is being run.
Despite the jokes about Fed policy, I think few people today have
any doubt about the Fed's objectives. Policymakers emphasize and
reemphasize the importance of achieving low and stable inflation
and that the Fed will act to the full extent of its powers, consistent
with that objective, to cushion fluctuations in income and employment.
Financial markets understand that the Fed is prepared to act decisively
in times of national emergency and financial market distress, as
evidenced by Fed actions in response to the terrorist attacks last
September 11, to the Russian default and near collapse of Long Term
Capital Management in the late summer and fall 1998 and the stock
market panic in 1987.
My aim this morning is to illuminate a part of the policy process
that is, I believe, not very well understood-the use of informal,
or anecdotal, information in the policy process. I'll discuss the
nature of this information and how we use it. I'll start, though,
by outlining the role of formal data.
Before proceeding, I want to emphasize that the views I express
here are mine and do not necessarily reflect official positions
of the Federal Reserve System. I thank my colleagues at the Federal
Reserve Bank of St. Louis for their assistance and comments, especially
Howard Wall, Research Officer, but I retain full responsibility
for errors.
The Role of Formal Data and its Pitfalls
To avoid misunderstanding, I must begin by emphasizing that the
basic picture of the economy comes from the formal data published
by statistical agencies. Among other things, the data include the
national income accounts; labor market statistics on employment,
unemployment and related measures; price and wage statistics; industrial
production and capacity utilization; financial market statistics
on monetary variables, interest rates, security prices and banking
markets; international trade and capital flows. We have available
similar data on economies around the world.
Our basic knowledge of the economy depends on the formal data.
We use these data in our econometric models. Formal data have many
advantages. We know the statistical procedures by which the data
are created and have historical records, well back into the 19th
century in many cases, from which we can study regularities of economic
behavior.
I like to think of informal data as providing insight into the
formal data. The insight runs across several dimensions, including
timeliness and potential measurement and even conceptual errors
in the formal data.
Consider timeliness. When making monetary policy decisions, members
of the Federal Open Market Committee (FOMC) need to know as much
as possible about current and future economic conditions. Unfortunately,
the formal data on which we rely lag current economic conditions.
For example, the Fed has an incomplete picture of the economy's
two most important indicators, growth and inflation. The Bureau
of Economic Analysis releases formal estimates of Gross Domestic
Product (GDP) with lags of a month or more. Moreover, the data are
subject to frequent and major revisions. Price indexes also are
produced with a lag and are sensitive to factors that may be temporary,
such as fluctuating energy prices, and measurement error. Given
these problems, it is easy to see how monetary policymaking has
often been likened to driving a car with a blacked-out windshield
and fogged-up side windows.
To get an idea of the scale of the difficulty of using formal
data, let's take a look at the timeliness and uncertainty of estimates
of GDP, the most comprehensive measure of economic conditions. Just
over two weeks ago, the advance GDP estimate was released, indicating
that real GDP had risen at an annual rate of 0.2 percent in the
fourth quarter of 2001. About two weeks from now we will see preliminary
GDP estimates for the fourth quarter and a month after that we will
see final estimates.
Since 1978, two-thirds of the revisions between the advance estimate
and the final estimate of real quarterly growth were between -0.6
and 0.9 percentage points. This means that the likely range of the
final estimate of fourth-quarter real GDP growth-which we won't
see until the end of this quarter-is between minus 0.4 and plus
1.1 percent. To compound the problem, the so-called final estimate
isn't the last estimate. Every summer, in July or August, the final
estimates are revised and every three years we get major revisions.
Since 1978, latest estimates have differed from final estimates
by an average of 1.2 percentage points in either direction. Thus,
the latest estimate for 1980, say, changes over time. As a consequence,
economists like to say that history is never what it used to be!
In principle, the estimates keep getting better as the statisticians
find improved source data, refine estimation methods, and improve
underlying concepts.
When one considers the enormous task of estimating the size of
the U.S. economy, these problems might seem small. But, for making
monetary policy decisions, they can make a critical difference.
In fact, the range of uncertainty over growth rates can imply opposite
short-run monetary policy responses. Given the uncertainty, it is
often best for policymakers to sit tight, waiting for the uncertainty
to be resolved by new information and revised data. What this means,
obviously, is that sometimes it is clear in hindsight that policy
action should have come sooner, or even in a different direction.
Of course, official growth and inflation data are not all that
we have to go on. Most financial data are very up-to-date, and futures
markets allow us to peer into the future-or at least into markets'
expectations of the future. In addition, some real economic data,
such as initial unemployment claims, auto and steel production,
and electricity consumption, are available every week. Because these
data are used to construct the official GDP estimates, they can
provide partial pictures of current-quarter GDP.
Other data are used as leading or coincident indicators. Economists
and analysts rely on past patterns of these indicators to provide
insight into the current business cycle phase. Average weekly hours
in manufacturing are a leading indicator because firms tend to adjust
work hours before increasing or decreasing their workforce. Nonagricultural
employment is a coincident indicator because it tends to rise and
fall with GDP. In addition, some data are used to identify turning
points in the economy. For example, many analysts follow the ratio
of inventories to sales because it has tended to peak at the same
time that the economy is in a trough.
While the Fed relies heavily on formal data and sophisticated
statistical methods for analyzing the data, staff and policymakers
alike spend a lot of time collecting and using anecdotal information
that we gather from an extensive network of contacts. This anecdotal
information helps us to see what is going on in the economy almost
as it is happening. Also, because it is collected from the people
who are actually making day-to-day business decisions, it helps
us to understand why trends in the data are occurring.
For the rest of this talk I am going to discuss the role that
anecdotal information plays in Fed policymaking. I will outline
the ways in which we gather this information and then describe the
various ways that we use it. I will also discuss briefly some recent
evidence that anecdotal information adds value beyond what we get
from other sources. And finally, I will touch on some of the dangers
and pitfalls of relying too heavily on anecdotal information.
How We Obtain Anecdotal Information
The Fed gathers its anecdotal information from a wide range of
sources. Directors of the Federal Reserve Banks and their branches
provide written economic reports of conditions in their regions.
Reserve Bank presidents and economists travel around their Districts
meeting with business people and bankers discussing conditions in
their industries. Reserve Banks maintain a network of industry contacts
who are contacted on a regular basis in advance of FOMC meetings.
We make additional effort to maintain contacts in bellwether industries,
such as freight and transport, whose activity is closely related
to total economic activity. We also pay close attention to the real
estate industry, where the level of activity might be a good indicator
of the confidence that people have in the future. After all, for
most people the purchase of a home is the largest financial commitment
that they will ever make. If they are willing to continue buying
homes when the economy is slowing, as has been true recently, they
must be reasonably confident about their personal economic outlook.
In addition, our eyes and ears are always open, looking for emerging
economic trends. A well-known example of this hands-on approach
is that the president of the Minneapolis Fed has been known to make
regular visits to local shopping malls to count the cars in the
parking lots. I routinely make a number of phone calls to business
contacts before FOMC meetings. I seek specialized information highly
dependent on current circumstances. For example, during one of my
trips after September 11 I struck up a conversation with a Southwest
flight attendant and learned that the airline was continuing to
hire and train new flight attendants. That information reinforced
what I knew from press reports, that Southwest was not cutting flights
and had an optimistic view of the future.
How We Use Anecdotal Information
The vast amount of anecdotal information collected throughout
the Federal Reserve System is used for a variety of purposes. Most
systematically, it is used to produce the "Summary of Commentary
on Current Economic Conditions"-commonly known as the Beige
Book-which is published two weeks before every FOMC meeting. To
produce the Beige Book, each Federal Reserve Bank gathers information
about its District through a network of contacts. The 12 District
reports are collected together by an assembling Bank, whose staff
prepares the national summary of economic conditions. The Beige
Book, by the way, is available on the web site maintained by the
Board of Governors.
The anecdotal information collected makes its way into FOMC meetings,
where Fed governors and Reserve Bank presidents present their views
on the economic outlook. In addition to their use in assessing the
state of the economy, the anecdotes might be used to illustrate
a point, thus adding impact to the comments. For example, a Bank
president could say that "the market for construction material
in my District continues to be tight and prices are rising."
Or, he could say the same thing and add, "The situation is
so tight that we have had reports of truckloads of drywall being
hijacked." The addition of the anecdote (which happens to be
an actual one from another District) adds more to the report than
could several charts or tables.
Anecdotal information also can be used to confirm or to help understand
ongoing trends that arise from the formal data. For example, during
the late 1990s, the unemployment rate fell well below what many
people thought was the level where inflation would start to take
off. If we had relied only on the formal data, the Fed might have
overlooked what firms and workers were doing to drive down the unemployment
rate and how they were responding to tight labor markets. For example,
we learned from our contacts in businesses that companies were willing
to leave positions unfilled rather than bid aggressively for labor.
My interpretation of this information was that firms were convinced
that inflation would remain low and that they dared not let wage
costs increase, because they were unlikely to be able to recover
those costs in higher prices.
For a specific example, the owner of a manufacturing firm in Louisville
told us how he was able to expand employment and production even
though most of his traditional workforce-prime aged men-were already
employed. This challenge led him to rethink his production process
to make it a better match for the workers that were available to
him. The result was that, whenever possible, his production methods
were changed to reduce the requirement for physical strength.
We heard many similar stories about how firms were providing basic
skills, making their work schedules more flexible, providing transportation
for their workers, and so forth, to cope with the rapidly changing
nature of their workforce. Without this first-hand knowledge of
firms' ability to respond to competitive challenges and new environments,
the Fed might not have known that unemployment could keep falling,
at least for a time, without inflation being ignited.
Our network of contacts is also useful for identify emerging trends.
For example, well in advance of it actually occurring, we had a
good idea that firms' health insurance premiums would increase at
double-digit rates in 2001. We knew this increase was coming before
it appeared in official data because our contacts told us in mid
2000 about the health insurance contracts they were signing for
2001.
Another good example of anecdotal information came from one of
our Branch Directors who noted in the summer of 2000 that loan demand
at his bank was falling and that other firms in his area were beginning
to experience problems. This information was important because,
at the time, the economy was growing rapidly and nearly all forecasts
indicated that rapid growth would continue. Nevertheless, reports
of this sort continued to surface throughout the rest of 2000 and
into 2001, helping the Fed to get ahead of the recession by starting
to lower its federal funds rate target early last year, even though
official GDP data available at the time suggested that the economy
was still going strong.
While most of the anecdotal information collected by the Fed is
used to supplement other information at our disposal, for some one-time
events the anecdotal reports become the primary source of information.
In these instances, standard data are not reliable guides because
history has not recorded a pattern for how the economy is likely
to respond. An example such an event was the series of terrorist
attacks on September 11th, which had immediate and dramatic economic
consequences, although we had no history to use to predict what
these consequences might be. Nonetheless, we were able to use our
network of contacts to get a good idea of the sectors that were
affected the most, weeks before any formal data were available.
We found out very quickly that the Fed's injection of liquidity
into the banking system had been successful, in that few banks reported
having liquidity problems despite the near-complete shutdown of
financial markets. We also found that retail sales came to a halt
in the two to three days after the attacks but surged back to near-normal
levels by the weekend, that manufacturers in the District were anticipating
that they would be reducing their output by an average of 10 percent,
and that auto sales for the period might be down by as much as 50
percent. Within a few weeks, our contacts told us that auto sales
in October were in fact strong, in response to the zero-interest
financing incentive offered by auto manufacturers. All of this information
was vital in the weeks immediately following the attacks when the
Fed had to react very quickly while navigating the uncharted waters
of September and October. Indeed, based on anecdotal reports and
experience, but without any substantial amount of formal data applying
to the period after September 11, the FOMC cut the intended federal
funds rate on September 17 and again on October 2.
Value Added
I have already mentioned some of the ways that anecdotal information
adds value to Fed policymaking, but my comments themselves are only
anecdotal. Recently, though, economists within the Federal Reserve
System have tried to use more technical methods to evaluate the
Beige Book as an indicator of present and future economic activity.
The first such study was done at the Minneapolis Fed and found that
the Beige Book has been an accurate predictor of real growth in
the current quarter. They also found, however, that the Beige Book
did not improve upon private sector forecasts of real growth. The
study concluded that the Beige Book's value is not in forecasting
economic activity, but in reflecting the economy. In other words,
the Beige Book was found to add value by providing insight and context
not found in formal forecasting models, while not improving on the
performance of these models.
More recently, research from the Dallas Fed has found stronger
empirical support for the Beige Book as a predictive tool. This
study found that the national summary of the Beige Book has significant
predictive content for current and future quarterly growth. Further,
it found that the Beige Book has predictive content beyond what
is provided by private forecasts. Of particular interest is that,
according to this study, the Beige Book appears to have been better
than alternative methods at identifying turning points in the economy.
Another potential source of added value is from the Beige Book's
12 regional summaries. The decentralized nature of the Beige Book
means that the Fed has an instrument for detecting regional differences
in the business cycle. Business cycle fluctuations are now thought
to be more heterogeneous across regions and sectors than they used
to be. Hence, one hears references to a "rolling recession"
that affects different regions with greatest severity at different
times. State and regional data, however, are much less complete
than national data-for example, Gross State Product data are produced
with a two-year lag. In this void, the Beige Book can help pinpoint
focal points of such a rolling downturn or a rolling recovery. In
fact, the Dallas Fed study suggests that, taken as a whole, the
regional sections of the Beige Book add predictive power beyond
what the national summary provides. Further, some of the regional
sections-including that produced by the St. Louis Fed-have been
useful on their own in predicting GDP growth one quarter ahead.
Dangers and Pitfalls
There are a number of dangers and pitfalls inherent with anecdotal
information, so a great deal of care should be taken in using it.
For one thing, despite the effort that the Fed puts into it, the
number of contacts is small from a statistical standpoint, and they
are not selected randomly. They tend to be in businesses that are
familiar to a director of a Fed Bank, who have voluntarily agreed
to serve as a contact, or whose manager or owner has been asked
to serve on a Fed Bank's advisory board. Because of this selection
process, numerous biases can arise. For example, perhaps the type
of person who would serve as a contact or be a member of an advisory
board would also tend to be more successful than the average businessperson.
If so, then the information that the Fed receives would tend to
underrepresent firms that are more likely to be experiencing difficulties.
Also, the responses might reflect the biases of the contacts rather
than be accurate representations of conditions. This bias would
not arise through any conscious misrepresentation, but perhaps through
the tendency for successful business people to be more optimistic
than the average person. An example of this occurred during a recent
lunch at our Bank when we hosted a group of residential housing
developers. The first time I went around the table asking them for
their outlook on future conditions in their industry, nearly every
one of them was quite upbeat. This near unanimity was surprising
because this was not long after September 11th and most of them
also felt that the overall economy was not in the best of shape.
I then asked them if their answers were really what they thought
would happen or if they instead reflected what they hoped would
happen. Several of them then admitted that their outlook was probably
more hope than expectations, and adjusted their answers accordingly.
The biases of the economist collecting and analyzing the anecdotal
information may also mean that it is not representative of general
economic conditions. For example, the economist might tend to pay
more attention to anecdotes that fit his or her previously held
beliefs. As a consequence, the overall impression that is conveyed
from the anecdotes in, for example, the Beige Book, might tend to
reflect the economist's personal views. It might also be that the
odd or quirky anecdotes are the ones that have the most influence
because they are the most interesting, even though they might not
be representative of general trends.
Summary and Conclusions
Because anecdotal information is inherently unscientific, the
Fed will continue to rely most heavily on formal methods when making
monetary policy decisions. Use of formal statistics is an important
discipline. Nonetheless, because these methods provide a far from
perfect picture of the economy, the Fed should continue to use anecdotal
information to help fill the gaps. Anecdotal information improves
upon our understanding of where the economy is and where it might
be going, most notably by providing information ahead of formal
data. The process of gathering the information puts us in direct
contact with people actually making day-to-day economic decisions.
The information forces us to question the formal data and provides
a view of the economy that formal methods simply miss.
This constant process of testing the formal data against the anecdotal
reports, and vice versa, strengthens our understanding of both types
of information. I know that I did not understand the scale and importance
of the effort when I came to the Fed about four years ago, and I
suspect that few observers outside the Fed appreciate the role of
anecdotal information in the monetary policy process. That is why
I thought this topic deserves some attention, and I hope I've been
successful in explaining to you how the process works.
