*I appreciate comments provided by my colleagues at
the Federal Reserve Bank of St. Louis. Robert H. Rasche, senior
vice president and director of Research, and Daniel L. Thornton,
vice president in the Research Division, provided especially valuable
assistance. I take full responsibility for errors. The views expressed
are mine and do not necessarily reflect official positions of the
Federal Reserve System.
Fed Transparency: How, Not Whether
Central bank transparency is a topic almost as discussed
as policy actions themselves. It has always been true that market
participants have wanted to know the implications of policy actions
for the likely future course of monetary policy, but the longstanding
practice of central bank secrecy frustrated their search. In recent
years, monetary policymakers have disclosed much more than they
did in the past, partly because of growing interest in being more
accountable and partly because of recognition that policy actions
will be more effective if the market understands them better.
Discussion of transparency has gone well beyond the
financial pages. The past decade has seen numerous professional
papers on transparency issues. In this literature, transparency
is taken to mean public disclosure, and much of the discussion
has centered around questions such as: How specific should central
banks be about their policy objectives? Should they announce the
weights they apply to their inflation and output stabilization objectives
in conducting monetary policy? Should central banks disclose their
economic forecasts? Should transcripts of the policy debate be published
and, if so, how soon? Should policy-making meetings be televised?
My intent today is not to review the entire range
of transparency debates but instead to concentrate on issues relating
to the effects of monetary policy information on markets and on
the effectiveness of monetary policy. I certainly do not believe
that political accountability issues are unimportant but my chosen
topic is large enough to more than fully exhaust the time available
today.
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—especially Robert Rasche,
Senior Vice President and Director of Research and Daniel Thornton,
Vice President in the Research Division—for their assistance
and comments, but I retain full responsibility for errors.
My plan is to proceed by first outlining my model
of how the economy works. That view is, I believe, the essential
starting place for a discussion of transparency. I will then discuss
two cases in which, depending on what view you have, market participants
did not interpret Fed statements correctly or the Fed did not communicate
clearly. Under either interpretation, there was some miscommunication.
I will use ‘transparency’ as shorthand
for accurately conveying accurate information including all
the information market participants need to form opinions on monetary
policy that are as complete as possible.
Fundamentals of Macroeconomic Equilibrium
Analysis of policy communication logically begins with a description
of the economic interaction between the central bank and the markets.
I’ve provided my view of this interaction on several occasions;
here I provide just enough of a sketch of this view to enable me
to discuss communication issues.(1)
At a highly abstract level, I believe that the appropriate model
of the economy is that markets behave in an efficient, fully informed
way. Equilibrium requires that market participants form accurate
expectations about the behavior of the central bank. The economy
will function most efficiently if central bank policy has two features.
First, the central bank must have clearly understood, appropriate
and feasible objectives. Second, the central bank must have a highly
regular and predictable policy rule or response pattern that links
policy actions to the state of the economy, including all information
relevant to assessing the economy’s probable future course.
Pushing the idea of a full rational expectations equilibrium one
step further, there should be a political equilibrium in which the
central bank pursues objectives broadly accepted in society. Without
broad political support, monetary policy objectives are subject
to change through normal democratic processes and such change, or
the prospect of it, adds to uncertainty about future monetary policy.
With regard to objectives, the Federal Open Market Committee (FOMC)
has stated repeatedly that one of its objectives is a low and stable
rate of inflation. Although the FOMC has not quantified that target,
for present purposes it is useful to discuss communications issues
as if the FOMC had announced a specific target. Put another way,
with regard to market behavior I believe that the difference between
an explicit target and one inferred from FOMC decisions is minimal
today and has been for some years.
The FOMC also has the objective of maximum possible stability
of output and employment. Taken together, low inflation and output
stability along the economy’s growth path are believed to
contribute to maximum possible economic growth over time. Because
of its importance to output and employment stability, it is also
useful to point explicitly to the objective of financial stability.
Stabilizing policy responses to severe market disruptions such as
a stock market crash or a liquidity crisis further contribute to
fostering maximum possible economic growth.
The FOMC implements policy by setting the intended federal funds
rate. As is well known, a central bank cannot achieve a stable outcome
for the economy if it pegs the interest rate at an inappropriate
level for any length of time. Thus, the central bank must change
its interest rate target from time to time to achieve its objectives.
In my abstract model of the economy, the market and the central
bank have the same information base; neither has an informational
advantage. As new information arrives, the appropriate interest
rate to achieve policy objectives may change. Given my assumption
that the market and the central bank have the same information,
all players respond the same way to the arrival of new information.
The central bank determines the appropriate policy response knowing
that the market also has the same information and understands its
implications for the economy and for policy actions.
At a highly abstract level, I believe that this model accurately
describes the way the U.S. economy has been working in recent years.
As we add more and more detail to the model, we find areas in which
the equilibrium is not complete. Thus, my view is that the economy
has been converging toward a full rational expectations macroeconomic
equilibrium, but is not all the way there as yet. In particular,
over the last quarter century there has been enormous progress in
improving the clarity of the Fed’s objectives and in the Fed’s
discipline in pursuing the objectives. With regard to the inflation
objective, there is a world of difference between today’s
situation and that prevailing in the 1970s.
There has also been enormous progress in provision of more accurate
and timely information about policy actions. The FOMC announces
its policy actions on the afternoon of the conclusion of each regularly
scheduled meeting, and promptly after any interim meeting. The Fed
is more open in many other ways as well; for example, the FOMC now
releases a policy statement at the conclusion of its meeting and
dissents, if any, are also disclosed at that time.
My fundamental conception of the Fed’s communication challenge
is to further the progress toward a more complete rational expectations
equilibrium. Put another way, my question is this: How might the
Fed modify its communications strategy so that the market can converge
on a rational expectations equilibrium with less error than we observe
today?
Miscommunication—Two Cases
It is instructive to consider examples in which communications
were less clear than they might have been and to analyze how such
problems might be avoided in the future. Communications successes
are also worth studying. There is a growing literature along these
lines, such as analysis of the market effects of the change in FOMC
practice in February 1994 to immediate disclosure of policy decisions
at the conclusion of FOMC meetings.
Accurate communication is far more difficult than it seems at
first glance. Complete accuracy requires that speaker and listener
interpret actions and words the same way. In a normal conversation,
individuals have an opportunity to clear up ambiguity by raising
questions about intended meaning. It is possible to ask for clarification,
or ask again, before acting. What central bank officials (and, of
course, other officials as well) say, however, can have immediate
market impact; market participants may act before ambiguities or
miscommunication can be corrected. This fact imposes special burdens
on central bankers.
To illustrate how difficult the communications process is in the
central bank context, let me relate to you an exercise I go through
at the end of each FOMC meeting. Before the decisions of the meeting
are made public, I estimate—“guess” is a much
better word—the market reaction to the policy action and press
release that are made public at 2:15 p.m. after the meeting. Then
I listen to the radio or a cable news channel to determine the how
the bond and stock markets respond. Ordinarily, but not always,
I get the direction of the market responses correct, but my estimates
of the magnitudes of the market reactions are often wide of the
mark. My personal experience is that I find it exceedingly difficult
to predict how people will interpret policy actions and the nuances
of the press release. I suspect that other FOMC participants perform
similar exercises, though I have not asked any of them.
I’ve sometimes thought I should keep a formal record of
my market predictions, but have not yet decided to do so. It could
be a sobering exercise for all FOMC members to maintain such a record.
Communication is obviously imperfect if the speaker—the FOMC
in this case—cannot predict accurately how listeners will
respond.
Now consider two specific examples of FOMC communications that
I believe were misread. The first is the evolution in the announcement
of the “tilt” in the directive and the second is the
communication last May about “an unwelcome substantial fall
in inflation.” I emphasize that I’m offering my personal
interpretation of these cases; other FOMC members may have different
interpretations.
In the early 1980s the FOMC began to vote on language pertaining
to possible future policy actions. This language was alternatively
called the “tilt,” “bias,” or “symmetry”
of the policy directive. The language was generally regarded as
applying to possible policy action through the period ending at
the next FOMC meeting. Historically, the FOMC did not release this
language until the minutes of a meeting were published subsequent
to that next regularly scheduled FOMC meeting. That meant that the
statement, when released, had no information value about the probable
direction of policy actions because the statement referred to a
period already past.
In an effort to be more transparent, the Committee decided in
December 1998 that it would release the tilt language immediately
with its policy action on the conclusion of a meeting when it expected
the information to be particularly important. The minutes of that
meeting, released in late January 1999, contain a paragraph on the
Committee’s discussion of disclosure policy. A key passage
from the minutes reads as follows:
Nonetheless, the members decided to implement the previously
stated policy of releasing, on an infrequent basis, an announcement
immediately after certain FOMC meetings when the stance of monetary
policy remained unchanged. Specifically, the Committee would do
so on those occasions when it wanted to communicate to the public
a major shift in its views about the balance of risks or the likely
direction of future policy. Such announcements would not be made
after every change in the symmetry of the directive, but only
when it seemed important for the public to be aware of an important
shift in the members' views.
At the conclusion of the meeting in May 1999, the FOMC for the
first time released a statement that included the “tilt”
in the policy directive. The formal statement referred to “the
federal funds operating objective during the intermeeting period.”
Many members of the FOMC believed that the market overreacted to
the May tilt statement, and to subsequent tilt statements as well.
The statements did attract considerable attention, and market analysts
began to speculate about changes in the intended funds rate at future
FOMC meetings based on the tilt, or symmetry, announced by the FOMC.
The market reaction to the statement released immediately after
the May 1999 FOMC meeting should not, perhaps, have been a surprise
to the Committee. The Committee had said, after all, in its the
minutes of the December 1998 meeting that it would make such an
announcement “when it wanted to communicate to the public
a major shift in its views … .”
In an attempt to clarify its communications, the FOMC established
a subcommittee to review both its policy directive and the public
announcement following FOMC meetings. Communications practice changed
in two respects. First, the FOMC would issue a statement after every
meeting. That step eliminated the possibility that the mere existence
of a statement would be treated as an unusual event signaling a
major change in policy.
The second step was a new “balance-of-risks” statement
that assessed the outlook for price stability and sustainable economic
growth in the foreseeable future. Despite the FOMC’s stated
intention that its new “balance-of-risks” was not to
be interpreted as an indictor of future FOMC actions, the evidence
suggests that it was one of the pieces of information that market
analysts did use to form expectations of a likely near-term policy
action.(2) My perception, however,
is that the balance-of-risks language did not come to have a completely
settled meaning in the market.
For my second example, consider the statement following the FOMC
meeting last May that referred to “an unwelcome substantial
fall in inflation.” In subsequent commentary in the financial
press this statement was interpreted to mean one or more of the
following things:
a) A cut in the intended funds rate at the June 2003 meeting
was likely.
b) Any increase in the intended funds rate within the next year
was highly unlikely.
c) The FOMC would implement “unconventional monetary policy
actions” such as aggressively purchasing long-term Treasury
bonds.
Interpretation (c) gained force and a major rally in long-term
Treasury markets ensued, driving the 10-year Treasury rate to a
more than 40-year low of 3.13 percent.
Speaking strictly for myself, I believe there are two important
points that the statement of May 6 tried to communicate which didn’t
really come across. First, inflation has now receded to a level
where for the first time in 40 years inflation risks are symmetric:
from the current inflation rate neither sustained increases nor
sustained decreases are desirable. Second, in the words of my FOMC
colleague Governor Bernanke, “… FOMC behavior and rhetoric
have suggested to many observers that the Committee does have an
implicit preferred range for inflation. Most relevant here, the
bottom of that preferred range clearly seems to be a value greater
than zero measured inflation, at least 1 percent or so.”(3)
On several occasions in the past I have stated that my preferred
inflation target is zero inflation, properly measured. Since I believe
that the major price indexes employed today are subject to some
upward bias and measurement error, the goal “zero inflation,
properly measured” translates into a low positive measured
rate of inflation. In my judgment, one percent measured inflation
for the consumption price index is in the neighborhood of price
stability as I define it.
To me, though, an announcement that inflation is now down to an
appropriate long-run target should not by itself have led to a sharp
decline in the 10-year bond rate. What I think happened was that
the market, seeing that the intended federal funds rate was down
to 1 percent, thought that the Fed was running out of room to implement
policy through setting a target fed funds rate. If the Fed were
to switch to setting a target for long-term interest rates, then
such a policy would reduce or eliminate for a time downside price
risk on long-term Treasury bonds. That would justify bidding the
10-year bond price up (the rate down), because the price risk would
become one-sided—bond prices could go up but not down, or
at least not down by very much very soon. Over time, however, the
market came to believe that the FOMC was not contemplating the need
for an unconventional policy in the near term, and bond prices fell.
Indeed, bond yields backed up to a level above where they had been
just before the May FOMC meeting.
Disclosure Strategy
Given my emphasis on the economic purpose of disclosure, I see
no room for merely satisfying curiosity about what goes on in FOMC
meetings. The general nature of what goes on in meetings can easily
be inferred by reading meeting transcripts, which are released with
a five-year lag. The appropriate communications goal, in the context
of how the economy functions, should be to minimize market uncertainty
about monetary policy. It is important to emphasize that uncertainty
about future monetary policy actions cannot be eliminated because
those actions depend critically on information that cannot itself
be predicted. What needs to be minimized, therefore, is uncertainty
about central bank responses to new information.
I’m going to concentrate my discussion on the policy statement
issued at the conclusion of each FOMC meeting, but some of my comments
have broader applicability. The communication at the conclusion
of each FOMC meeting is a critical one because market participants
are primed to react to news of a policy action and its rationale.
The statement is necessarily short and it sets the stage for FOMC
members to provide subsequent more thorough discussions of policy.
I’ll concentrate on two aspects of the statement. The first
is the extent to which the statement should provide a forecast in
some form of future policy actions and the second is the structure
of the statement itself.
Given my rational expectations macroeconomic model and my desire
to create a more complete equilibrium—an equilibrium in which
expectations errors are minimized—the central communications
issue is to explain to the market the nature of the policy rule
that determines how new information feeds into policy actions designed
to achieve as closely as possible the central bank’s policy
objectives. Achieving clarity with respect to policy objectives
is actually quite simple compared to explaining the nature of the
policy rule.
The fundamental problem is that there is no policy rule by which
we can calculate the appropriate policy action from observed data.
There is instead a regularity to policy of the sort “you know
it when you see it.”
Sometimes we observe a striking change in some particular variable,
such as the unemployment rate, that all but demands a policy response.
Most of the time, though, policy actions flow from an accumulation
of data most of which point in the same direction. It just is not
easy to describe “you know it when you see it.” I would
be absolutely delighted if researchers could provide a quantified
policy rule, at least as a base case. The rule suggested by John
Taylor is helpful, but very incomplete. I think it unfortunate that
we have not seen in the professional literature an evolution of
a policy rule that builds substantially on the work begun by Taylor.
But the problem is a very difficult one; for one thing, it is necessary
from time to time to discount changes in an important economic variable
because of suspected anomalies in the statistics themselves.
Thus, we have to live with the unfortunate fact that the monetary
policy world is one of “I’ll know it when I see it.”
We need to keep that fact in mind when designing communications
policy.
Explaining a policy action—elucidating the considerations
that led the FOMC to decide to adjust the intended funds rate, or
to leave it unchanged—is worthwhile. Over time, the accumulation
of such explanations helps the market, and perhaps the FOMC itself,
to understand what the policy regularities are. It is also important
to understand that many—perhaps most—policy actions
have precedent value. If the FOMC takes action A in circumstances
X, the next time circumstances X arise the FOMC should also take
action A, or have good reason not to do so. One of the advantages
of public disclosure of the reasons for policy actions is that the
required explanation forces the FOMC to think through what it is
doing and why.
Discussing future policy actions is a different matter. In my
view of the world, future policy actions are almost entirely contingent
on the arrival of new information. For that reason, I believe that
an FOMC forecast, or tilt toward, a specific future policy action
is more likely to be misleading to the market than helpful. It is
true that at the conclusion of a meeting I have a sense of the probabilities
of various future policy actions, and I suspect that other FOMC
members think about the policy process the same way. I might believe,
for example, that new information would be very unlikely to lead
me to want to raise the intended funds rate at the next meeting
but might, in combination with information already known, make the
case for cutting the intended rate. And I might assign a probability
to a future cut of 0.5, or 0.3, or some other value. But even in
this situation I would not want to rule out an increase in the intended
rate for I can certainly imagine new information that would compel
an increase.
Question: could the FOMC as a practical matter decide on the probability
and convey that probability accurately to the market? My own view
is that only rarely could the FOMC agree on what the probability
should be, and even then it would be extremely difficult to convey
that probability to the market. Moreover, if the probability is
high, it seems to me that in most cases it would make more sense
to simply take the policy action at the current meeting rather than
broadcast it as likely at the next meeting.
The old “tilt” language caused problems, I think,
precisely because different FOMC members had different interpretations
of what probabilities attached to what words. And I think the market
view was, at least sometimes, that if the FOMC chose to change the
bias, it must be doing so to announce a significant probability
of future policy action. I think some observers also tend to react
as follows: If the probability is high, why shouldn’t the
FOMC act now? If the probability is low, why talk about it? If the
probability is in a middle range, will disclosing the tilt help
the market to price securities more efficiently—that is, more
in line with the true likelihood of future policy action?
Furthermore, the tilt language was sometimes used in an effort
to reduce the number of dissents in the FOMC. In this case, the
language may have provided inaccurate information, because the majority
may not have believed that there was any significant probability
of future policy action in the direction indicated.
Another problem is that of acting consistently with guidance about
the probable direction of future policy. Sometimes new information
arrives that is clearly compelling in the direction of not
acting in accordance with the guidance. A forecast of a policy action,
made before the new information arose, may then have created a dilemma
for a central bank. The central bank then either breaks what the
market regards as a commitment or lives up to the commitment at
the cost of ignoring new information calling for a different policy
action. However, more often information will be indecisive; once
guidance is announced, the burden of proof tends to shift toward
showing why the forecasted action is inadvisable whereas without
guidance the burden of proof tends toward justifying an action.
All in all, then, I’ve come to the view that FOMC language
forecasting future policy actions is probably counterproductive
in most circumstances. I do not, however, rule out the desirability
of forecasting future policy in some cases given that the rational
expectations model from which I am reasoning is clearly an abstraction.
What I think we need to do is to analyze the circumstances under
which the abstract model provides misleading guidance with respect
to communications strategy.
It is true that policy works in part by changing expectations
and therefore the term structure of interest rates; that is the
basic argument favoring disclosure of future policy direction. However,
the crux of the matter is this: If the market fully understands
the policy rule, or policy regularity, and has the same information
the FOMC has, then an FOMC forecast of future policy direction is
useless information because it is redundant. If the market and the
Fed have the same information, then the market can determine the
probabilities that new information will arrive pointing toward future
policy actions. Understanding policy objectives and the policy rule,
the market can put itself inside the Fed’s head and make the
same guesses the Fed can make.
If information on the Fed’s thinking about its future policy
direction is not redundant, then that fact alone does not necessarily
call for the Fed to forecast future policy actions. The issue for
me is quite different. If the market doesn’t see what I see,
why not? What is the market missing, and what do we make of the
fact? Perhaps the better course would be to disclose the underlying
information the market is apparently missing, or call attention
to information the market is neglecting. That to me is a better
strategy than hinting at an unconditional policy direction, because
the essence of what the market needs to know is not the intended
federal funds rate in six weeks. What the market needs to know is
the policy response function by which the central bank acts in a
consistent way over time and one that is efficient in fostering
success in achieving policy objectives.
This discussion assumes that the market is missing something.
But, could the problem be that the market sees something I do not?
How can I be so sure that I know the appropriate direction for future
policy actions? If it is the Fed that is missing something and not
the market, then disclosing a policy tilt will clearly be misleading,
or the odds are that it will turn out to be misleading.
Historically, the FOMC (and other central banks) went to great
lengths to avoid providing guidance about future policy direction.
Indeed one of the arguments that the Fed used in the defense of
secrecy in the Merrill case in 1975 was that the immediate release
of the information in the directive or in FOMC deliberations would
produce expectations that would destabilize financial markets. That
argument is incomplete at best. Some disclosures clearly stabilize
rather than destabilize markets; secrecy can create incorrect market
guesses about what the Fed is doing. One such case arose on Thanksgiving
eve 1989, when the Open Market Desk intervened to supply reserves
for technical reasons. At this time there was no announcement of
the intended funds rate. The intervention was widely interpreted
by market participants as a signal that the FOMC had reduced its
target for the federal funds rate from around 8.50 to about 8.25
percent. It took several trading days before the market sorted out
the confusion. On this occasion secrecy produced unnecessary volatility
in financial markets. Numerous other examples provide convincing
evidence, in my view, that in general disclosure of actual policy
actions is stabilizing rather than destabilizing. But it is not
appropriate to generalize from the value of immediate disclosure
of policy actions to disclosure of “everything.”
To discuss the format of the policy statement at the conclusion
of each FOMC meeting, I’ll start with an observation. Suppose
the statement is confined to one page. With even those few words,
the richness of language and the importance of word order in conveying
meaning yields the result that the statement contains an enormous
range of possibilities. The multiplicity of possible meanings is
made even larger since each statement is read against the backdrop
of the previous one. Thus, what is relevant is not just word choice
and order but changes from the previous statement.
As an aside, the importance of statement changes can make it difficult
to improve the statement over time. To avoid misinterpretation of
changes, it is best if a changed approach or format can be announced
in advance so that the change in approach is clearly separated from
a change in policy.
If the statement is to convey policy intent accurately and with
minimal ambiguity—surely desirable characteristics in terms
of minimizing expectational errors in the market—then the
number of possible meanings must be narrowed in some way. One way
would be for the FOMC to chose among a relatively few standard phrases,
at least in language providing a summary statement of the policy
stance.
Some will regard this approach as providing “boilerplate”
language with little real meaning. My own judgment is that it is
better to provide boilerplate with clear meaning than rich language
with a multiplicity of possible meanings. It just is not true that
lots of words equals lots of disclosure and greater transparency.
Because the market responds immediately to policy actions and statements,
it is important that the FOMC not find itself in the position of
having to clarify its statements to correct misinterpretations;
explaining the explanation can add to uncertainty and raise questions
about future policy statements, which market participants might
come to expect to be clarified or interpreted. The best way to avoid
these problems is to narrow the range of phrases used in the statement.
As I explained earlier, my view is that the statement should concentrate
on explaining the policy action and its rationale, and not hint
at future policy actions. Given information available at the time
of a meeting, I believe that the standing assumption should be that
the policy action at the meeting is expected to position the stance
of policy appropriately. The purpose of the statement should be
to explain why the policy action, or lack of action, has positioned
policy appropriately given the information available.
As a matter of logic, the current balance-of-risks language creates
some ambiguity. If risks are assessed as unbalanced, why was policy
not adjusted further to create a balance going forward? A possible
answer is that an unbalanced risk assessment foreshadows future
policy action. But the “tilt” interpretation of an unbalanced
risk assessment seems at odds with the rationale for substituting
the balance-of-risks language for the previous tilt language. What
would be clearer, I think, would be to use the balance-of-risks
language to explain that information since the previous meeting
indicated that risks were becoming unbalanced in a particular way,
and for that reason the FOMC adjusted the intended federal funds
rate.
Separating growth risks from inflation risks, as in the May statement,
makes a lot of sense. When employment change and inflation data
are plotted in a scatter diagram, all four quadrants contain lots
of observations. Sometimes employment and inflation rise together,
or fall together. However, just about as often the two variables
move in opposite directions. Because all four quadrants are populated,
a summary policy judgment has to be communicated indicating the
FOMC’s weighting of the risks. It is relatively easy to explain
that a policy tightening was occasioned by a rising risk of higher
inflation and stronger employment growth, but when employment growth
and inflation are headed in opposite directions the summary policy
language needs to indicate that the FOMC acted, or didn’t,
because it gave more weight to the inflation risk than the employment
risk, or vice versa. The issue is not, by the way, that inflation
risk is more or less important than employment risk but rather that
current information might suggest that recent employment changes,
say, are transitory.
This discussion makes clear that a minimally accurate summary
statement explaining a monetary policy action is still pretty complicated.
The FOMC must weigh inflation risks, employment risks, and form
a judgment balancing or weighting the two risks. Beyond that, from
time to time special factors will intrude, such as the tragic events
of 9-11 or unusual liquidity crises.
Concluding Observations
Transparency is a worthy goal, but improving transparency is hard
work. My thinking is still evolving, but one thing I know is that
the more I consider the issue the harder it seems.
I’ve tried to present a framework for thinking about how
to improve transparency. I start with a view of the world based
on a standard rational expectations macroeconomic model. An efficient
equilibrium requires that the markets understand what the central
bank is doing. The communications challenge for the central bank
is to explain more thoroughly and completely what it is doing. That
means above all explaining how new information feeds into policy
actions. I have a lot of skepticism about forecasting future policy
actions because they properly flow from new information that is
not itself predictable.
Accurate communication requires settled meanings for words. For
any given word, we can consult a dictionary and we usually discover
that each English word has several meanings, which can be quite
different. There is no dictionary in which we can look up the several
meanings of a paragraph. The meaning of a policy statement—preferably
only one—must be established by the central bank, through
consistent practice over time and through more extended discussion
of what the language means.
I think it fair to say that systematic study of the how
of transparency is in its infancy, and hope that my remarks here
spark others to analyze these issues.
