The Fed’s Dual Mandate Responsibilities and
Challenges Facing U.S. Monetary Policy
Charles L. Evans
President and Chief Executive Officer
Federal Reserve Bank of Chicago
In the summer of 2009, the U.S. economy began to emerge from its deepest recession
since the 1930s. But today, two years later, conditions still aren’t much different from an
economy actually in recession. GDP growth was barely positive in the first half of the
year. The unemployment rate is 9.1%, much higher than anything we have experienced
for decades before the recession. And job gains over the last several months have been
barely enough to keep pace with the natural growth in the labor force, so we’ve made
virtually no progress in closing the “jobs gap.”
The Federal Reserve has responded aggressively to the deep recession and weak
recovery, cutting short-term interest rates to essentially zero and purchasing assets that
expanded its balance sheet by a factor of three. But since undertaking the so-called
QE2 round of asset purchases last fall, the Fed’s aggressive policy actions have been
on hold.
Some believe that this pause is entirely appropriate. They claim that the economy faces
some kind of impediment that limits how much more monetary policy can do to stimulate
growth. And, on the price front, they note that the disinflationary pressures of 2009 and
2010 have given way to inflation rates closer to what I and the majority of Fed
policymakers see as the Fed’s objective of 2%. These considerations lead many to say
that when adding up the costs and benefits of further accommodation, the risk of over-
shooting our inflation objective through further policy accommodation exceeds the
potential benefits of speeding the improvement in labor markets.
I would argue that this view is extremely, and inappropriately, asymmetric in its
weighting of the Fed’s dual objectives to support maximum employment and price
stability.
Suppose we faced a very different economic environment: Imagine that inflation was
running at 5% against our inflation objective of 2%. Is there a doubt that any central
banker worth their salt would be reacting strongly to fight this high inflation rate? No,
there isn’t any doubt. They would be acting as if their hair was on fire. We should be
similarly energized about improving conditions in the labor market.
In the United States, the Federal Reserve Act charges us with maintaining monetary
and financial conditions that support maximum employment and price stability. This is
referred to as the Fed’s dual mandate and it has the force of law behind it.
2
The most reasonable interpretation of our maximum employment objective is an
unemployment rate near its natural rate, and a fairly conservative estimate of that
natural rate is 6%. So, when unemployment stands at 9%, we’re missing on our
employment mandate by 3 full percentage points. That’s just as bad as 5% inflation
versus a 2% target. So, if 5% inflation would have our hair on fire, so should 9%
unemployment.
Today, I would like to explore further the implications of the Fed’s dual mandate
framework for monetary policy-making in today’s environment. And don’t worry, the
views I am about to express are my own and not necessarily those of my Federal
Reserve System colleagues.
Brief Update on the U.S. Economy
It’s useful to start with a brief update on the U.S. economy. The economic outlook
clearly has deteriorated this year. Early in 2011, most forecasters thought that the
recovery was gaining traction and that economic activity would increase at a solid—
though not spectacular—rate this year and next.
The financial repair process seemed to be progressing well, and, at least among large
firms with access to the bond market, borrowing costs were quite low. We also had
finally begun to see a long-awaited improvement in labor market conditions, with private
job gains running about one-quarter million per month during the winter of 2011 and the
unemployment rate falling about 1 percentage point over a four-month period. Higher
prices for energy and other commodities were taking a bite out of purchasing power and
the disasters in Japan were a drag, but these influences were expected to be temporary
and growth was expected to strengthen.
The news over the past several months has proved this forecast wrong. Gains in
employment have slowed markedly, and the unemployment rate has edged back up
over 9%. The earlier improvements in labor markets now appear to have reflected the
lagged influence of previous output growth and not—as we had hoped--the start of a
virtuous circle of hiring and spending. Furthermore, revised data now indicate that real
GDP began to decelerate in late 2010 and then barely edged up in the first half of this
year. Consumer spending was particularly sluggish. Importantly, the weakness in
growth began before the bulk of the effects of higher energy prices hit the economy and
before the disaster in Japan. This timing, and the continued softness of most economic
indicators into the early summer, indicates that the headwinds facing consumers and
businesses are even stronger than we thought.
What are these headwinds? First, even though credit conditions overall have been
improving, many households and small businesses still seem to be having trouble
getting credit. In addition, the repair process in residential real estate markets is
painstakingly slow, and households are still in the process of paring debt and adapting
3
to the huge losses in real estate and financial wealth that they experienced during the
recession.
Of course, these forces are not new—indeed, they are important reasons why in this
cycle forecasters never predicted rapid gains in output such as those that followed the
deep recessions in the 1970s and 1980s. But they now appear to be even deeper and
more persistent than we thought earlier in the year.
Many households and business may still feel they have inadequate buffers of assets to
cushion against unexpected shocks. This leads to cautious behavior that holds back
spending. For example, I regularly hear from business contacts that they do not want to
risk hiring new workers until they actually see an uptick in demand for their products.
They do not appear to be paring back at the moment, but they would rather sit on cash
than risk undertaking a potentially unprofitable expansion. In addition to these long-
running problems, continued uncertainty about the European debt crisis and the
difficulties dealing with the U.S. fiscal situation have held back growth.
Against this backdrop, the outlook has weakened substantially. Last June, most private
sector forecasters were expecting real GDP to increase 2-3/4% in 2011 and 3.1% in
2012. By early August, these forecasts had dropped to 1.6% and 2.7%, respectively.
This 2012 growth rate is barely above most analysts’ views of potential growth—so it
certainly won’t make much of a dent in the unemployment rate and other measures of
resource slack.
On the price front, with energy prices increasing markedly, headline inflation – as
measured by the 12 month change in the total personal consumption expenditures price
index - rose from about 1-1/4% last fall to 2-3/4% in July. Excluding food and energy,
PCE inflation has moved up from about 1% to 1-1/2% over the same period. Energy
prices have dropped sharply over the past month and the prices for many other
commodities also have softened. And with the unemployment rate still high and capacity
utilization low, resource slack is likely putting downward pressure on prices. In addition,
market measures of longer-run inflation expectations are at the low end of the range
they have been running since last November.
Putting these factors together, my outlook is for overall inflation over the medium term to
fall back towards core and remain below the 2% level I see as consistent with the price
stability leg of the Fed’s dual mandate.
Monetary Policy and the Dual Mandate
In my view, central banks should focus on medium-term inflation. Over shorter periods,
measured inflation rates are affected by all sorts of short-term influences, such as
fluctuations in food and energy prices that are beyond the control of monetary policy.
Furthermore, there are significant lags before policy actions influence inflation. So
reacting too strongly to short-run influences simply adds noise to the policy-making
process.
4
So, by this appropriate standard I think inflation likely will be below our goal of 2%. And
of course, unemployment is much above its natural rate. Thus, at the moment, there is
little conflict between our two goals. Both suggest at least some additional monetary
policy accommodation would be helpful. However, given how truly badly we are doing in
meeting our employment mandate, I argue that the Fed should seriously consider
actions that would add very significant amounts of policy accommodation. Such further
policy accommodation does increase the risk that inflation could rise temporarily above
our long-term goal of 2%.
But I do not think that a temporary period of inflation above 2% is something to regard
with horror. I do not see our 2% goal as a cap on inflation. Rather, it is a goal for the
average rate of inflation over some period of time. To average 2%, inflation could be
above 2% in some periods and below 2% in others. If a 2% goal was meant to be a cap
on inflation, then policy would result in inflation averaging below 2% over time. I do not
think this would be a good implementation of a 2% goal.1
With this in mind, I want to discuss the nature of policy-making under a dual mandate
when we are far from our goals.
What’s a Central Banker to Do? (Warning: Math Ahead)
Normally, the deviations of the real economy and inflation from our objectives are small
enough that any conflicts are minor. And the well-known Taylor Rule captures normal
policy adjustments well, appropriately weighting output gaps and inflation deviations in
the setting of our policy rate. However, the Taylor Rule is a rule-of-thumb, whose claims
of empirical validity are based on its ability to track policy during periods of relatively
modest volatility.2 The current recession is outside of the empirical experience of Taylor
Rules calibrated to describe Federal Reserve actions.
We need to look beyond heuristic descriptions like the Taylor Rule to a more complete
analysis of optimal monetary policymaking within a dual mandate framework. This topic
has been studied extensively in the macroeconomic literature. Interestingly, one of the
1 The Committee’s interpretation of its mandate often is expressed as inflation of “2 percent, or a bit less.”
This does not mean keeping inflation in a narrow band capped by 2%. The “2 percent, or a bit less”
interpretation of our price stability mandate comes from the responses to the Survey of Economic
Projections which FOMC participants submit four times per year, and in which the majority of participants
have said 2% is their long-run forecast under conditions that include appropriate monetary policy.
Because inflation is determined in the long run by monetary policy, it follows that these long-run forecasts
can be interpreted as participants’ views on the level of inflation most consistent with the Committee’s
mandate. The “or a bit less” is added because a minority of participants submit long-run forecasts that are
below 2%.
2 The exercise is described in Taylor, John B. 1993. “Discretion Versus Policy Rules in Practice,”
Carnegie-Rochester Series on Public Policy 39, pp. 195-214; and Taylor, John B. 1999. “An Historical
Analysis of Monetary Policy Rules,” in John B. Taylor (ed.) Monetary Policy Rules, University of Chicago

first modern treatments is due to John Taylor in an article published in Econometrica in
1979.3 This framework continues to be a mainstay of optimal policy analysis, as
evidenced by a large literature that includes work by Michael Woodford in recent years.4
Taylor expresses the central bank’s dual-mandate objective as monetary policymakers
attempting to minimize the weighted sum of squared deviations of inflation and the level
of output from their goal values. That is, a central bank attempts to minimize a simple
quadratic loss function like the following:
L = (π – π*)2 + λ * (y – y*)2
Here π and y are inflation and the (natural) logarithm of output, and π* and y* are the
policy goals for these variables. In most formulations, y* is the log of the level of
potential output—the level of output at which resource slack has a neutral influence on
the level of inflation. Thus, (given the properties of logarithms) y – y* is the usual output
gap, the percentage difference between actual and potential output. And π – π* is the
gap between the actual and desired rates of inflation. Ideally, we’d like both of these
gaps to be zero, but this usually won’t be the case. We measure the costs associated
with the overall deviation of actual outcomes from the ideal with the quadratic loss
function L. Note that for each policy goal, this loss function equally weights same-sized
misses above and below target.
The coefficient λ determines the relative weight policymakers give to their misses on
real output versus those on inflation. If λ is equal to 1, then a 1 percentage point
deviation of inflation from its target gets the same weight in computing the overall costs
of being away from the optimum as a 1 percentage point deviation of output from its
potential.
However, Ken Rogoff (1985) and others have argued that, in order to avoid inflationary
biases that might creep into policy, a good, conservative central banker ought to
conduct policy as if λ were less than one.5 It’s reasonably conservative to set λ equal to
¼. That means the costs of a 1 percentage point output gap are judged to be only one-
quarter as high as the costs of a 1 percentage point deviation of inflation from its goal.
So a λ of ¼ puts a good deal of weight on keeping inflation near its goal.
Given that the Fed’s mandate is expressed in terms of employment, it is helpful to recall
Okun’s Law, which says that a 1 percentage point gap between actual and potential
output corresponds to a one half percentage point gap between unemployment and its
natural rate. Making this translation in the loss function, we see that the conservative

central banker attempts to minimize the equally weighted sum of squared inflation and
unemployment deviations:
L = (π - π *)2 + 1 * (u – u*)2
where u and u* are the actual and natural rates of unemployment.6
The bottom line is that a conservative and tough-minded central banker can still value
deviations in unemployment from the natural rate equally with deviations in inflation
from its target. Accordingly, an inflation rate of 5% against an inflation goal of 2%
presents this policymaker with an equal-sized loss as a 9% unemployment rate against
a conservative estimate of 6% for the natural rate of unemployment. (I call this
conservative, because while we think a number of factors such as increased job
mismatch and extended unemployment insurance benefits have temporarily boosted
the natural unemployment rate in the U.S., these factors are not expected to persist in
the long-run).
There also is an immediate corollary: If you aren’t as riled up over 9% unemployment as
you would be over 5% inflation, then you either put even less weight on unemployment
deviations in your loss function or you think that the natural unemployment rate is
substantially higher than 6%.
I’ll address the latter possibility later. However, I now want to turn to reasons why the
challenges to policymaking in the current situation are orders of magnitude larger than
those we face during more normal times. To preview, these are because: (a) we find
ourselves in the aftermath of a Reinhart-Rogoff type financial crisis, which has resulted
in severe headwinds weighing on the recovery process; (b) the economic costs of the
vast amounts of unused resources in the economy are very large; and (c) the zero lower
bound is a constraint on standard monetary policy actions, requiring a broader monetary
policy framework if we are to provide more policy accommodation.
Additional Challenge #1: Reinhart and Rogoff’s Great Contraction and Debt
Overhang
The Financial Crisis of 2008 left an enormous obstacle in the path of the U.S. recovery.
From peak to trough, $13 trillion of wealth was erased from household balance sheets.
Although the value of households’ assets declined dramatically, their debt levels
remained roughly the same. Many borrowers took on additional debt during the period
of high and rising asset valuations, and high employment and income growth were key
fundamentals for servicing these debt payments into the future. These debt burdens are
key contributors to the headwinds I discussed earlier when I talked about the economic
6 That is, Okuns’ Law says (y – y*) = 2*(u – u*), where u and u* are the actual and natural rates of
unemployment. Making this translation in the loss function (so squaring and multiplying by λ = ¼ yields L

outlook. As I noted then, they appear to be substantially more onerous than we had
expected.
In their book This Time is Different, Carmen Reinhart and Ken Rogoff documented the
substantially more detrimental effects that financial crises typically impose on economic
recoveries.7 Recoveries following severe financial crises take many years longer than
usual, and the risk of a second recession before the ultimate economic recovery returns
to the previous business cycle peak is substantially higher. In a related study of the
current U.S. experience, Reinhart and Rogoff show that the current anemic recovery is
following the typical post-financial crisis path quite closely, given the size of the financial
contraction.8 It would be nice to point to some features of the recovery that suggest
greater progress relative to the Reinhart-Rogoff benchmark. But those are hard to come
by.
It bears keeping in mind that the Reinhart-Rogoff predictions of a slow recovery are
based on historical averages of macroeconomic performances across many different
countries at many different times. They highlight a challenge we face today, but from the
standpoint of the underlying economic analysis, there is nothing pre-ordained about
these outcomes. They are not theoretical predictions—rather, they are reduced form
correlations. The economy can perform better than it did in these past episodes if policy
responds better than it did in those situations. In my opinion, maintaining the Fed’s
focus on both of our dual-mandate responsibilities is a necessary and critical element of
an appropriate response to the financial crisis that can produce better economic
outcomes.
Additional Challenge #2: Trying New and Nontraditional Policy Responses when
the Economic Stakes are Enormous
The second critical challenge is to take actions that respect both the feasibility of what
monetary policy can accomplish and the enormous risks to the future prospects of the
U.S. economy.
For me, these risks are clear. It is painfully obvious that the large quantities of unused
resources in the U.S. are an enormous waste. And it’s not just the current loss--over
substantial periods of time, the skills of long-term unemployed workers decline, their re-
employment prospects for similar jobs fade, and these reductions in skills have a lasting
effect on the future growth potential of the economy.
As I noted in the introduction, some argue that there currently are severe limits to what
further accommodative monetary policies can do to address these risks. It is essential to

delineate clear alternative scenarios in which this additional accommodation would be
futile. Such scenarios clearly exist, but they are very dark and pessimistic interpretations
of our current situation. I am personally much more optimistic and I don’t subscribe to
this pessimistic view; but let me describe it as I understand it.
Essentially, the hypothesis that limits aggressive policy actions assumes that the
productive capabilities of the U.S. have declined markedly in recent years and that
many workers who were productively employed just a few years ago are now essentially
obsolete. In this scenario, either much of the past decade of prosperity was an illusion
or, alternatively within the space of only a few years, the productive potential of the U.S.
collapsed for some unexplained reason.
I suppose it is natural to believe that some elements of the story are true. But for me,
the evidence for this is minimal, and the implications for productive capacity are
exceedingly pessimistic. And even if it is true, the market mechanism should cause
wages and prices to adjust in order to reemploy unused resources. For example, there
should be some lower real wage that would make it profitable for firms to fund the
necessary on-the-job training for workers who need some modest acquisition of skills.
According to this pessimistic hypothesis, something is preventing the market’s pricing
mechanism from achieving such results within a satisfactory time frame.
My own view is more optimistic and, I believe, more consistent with the idea that our
best days are ahead. Without a compelling explanation for the hypothesis that the
productive capability of the U.S. has been diminished, I think the evidence favors the
belief that aggregate demand is simply much too low today. After all, today there are
roughly 14 million unemployed Americans. Only a few years ago, there were only about
half that many. It is hard to believe that an additional 7 million Americans have suddenly
lost the necessary skills to work in today’s economy, and I have not seen any evidence
supporting such a dramatic and rapid loss of skills.
In the more optimistic case to which I subscribe, the productive capacity and potential
wealth of the U.S. have not been permanently damaged and currently unused
resources are still productive. Accordingly, in my opinion, monetary policy should be
used more aggressively to increase aggregate demand. In time, a reduction in
excessive risk aversion, supported by natural market forces would reestablish the
fundamentals that previously supported stronger growth and full employment. In this
way, large social losses would be mitigated. By stimulating aggregate demand, we can
have “Morning in America, again” and our best days can still be ahead of us.
But the clock is ticking—the longer we wait, the more likely it is that unutilized skills
diminish to the point that more permanent damage takes hold.
Challenge #3: Monetary Policy Held Back by Zero Lower Bound
By now, the third obstacle is quite well-known: the federal funds rate in the U.S. is
currently constrained by the zero lower bound on interest rates. Given the economic
9
scenario and inflation outlook I have discussed, were it possible, I would favor cutting
the federal funds rate by several percentage points. But since the federal funds rate is
already near zero now, that’s not an option.
To date, the Fed’s policy-making committee, the FOMC, has used a number of
nontraditional policy tools to impart greater financial accommodation. I have fully
supported these policies. Today, however, I simply think we need to do more.
In a recent Financial Times comment, Michael Woodford of Columbia University
discussed how greater clarity in policy communications would help.9 As I see it, current
financial conditions are more restrictive than I favor, because households, businesses,
and markets place too much weight on the possibility that Fed policy will turn restrictive
in the near to medium term.
The FOMC’s announcement in August that it anticipates short-term rates remaining low
through mid-2013 was certainly a step in the right direction, because it significantly
raised the hurdle for early policy tightening. However, I think our dual mandate
responsibilities and the strong impediments of the financial crisis argue for a more
aggressive approach.
One way to provide more accommodation would be to make a simple conditional
statement of policy accommodation relative to our dual mandate responsibilities. The
goal would be to enhance economic growth and employment while maintaining
disciplined inflation performance. This conditionality could be conveyed by stating that
we would hold the federal funds rate at extraordinarily low levels until the unemployment
rate falls substantially, say from its current level of 9.1% to 7.5% or even 7%, as long as
medium-term inflation stayed below 3%.
With regard to the inflation marker, we have already experienced unduly low inflation of
1%; so against an objective of 2 percent, 3 percent inflation would be an equivalent
policy loss to what we have already experienced. On the unemployment marker, a
decline to 7.5% would be quite helpful. However, weighed against an overly
conservative estimate for the natural rate of unemployment of 6%, it still represents a
substantial policy loss—indeed, one that is higher than the policy loss from high inflation
of 3%.
Accordingly, these triggers remain quite conservatively tilted in favor of disciplined
inflation performance over enhanced growth and employment, and it would not be
unreasonable to consider an even lower unemployment threshold that would be enough
progress to justify the start of policy tightening.

There are other policies that could give clearer communications of our policy
conditionality with respect to observable data. For example, I have previously discussed
how state-contingent, price-level targeting would work in this regard.10 Another
possibility might be to target the level of nominal GDP, with the goal of bringing it back
to the growth trend that existed before the recession. I think these kinds of policies are
worth contemplating—they may provide useful monetary policy guidance during
extraordinary circumstances such as we find ourselves in today.
The trigger policy I noted above and level-targeting policies may result in inflation
running at rates that would make us uncomfortable during normal times. But we should
not be afraid of such temporarily higher inflation results today. As I noted earlier, Ken
Rogoff (1985) has written that in normal times, we may want conservative central
bankers as institutional offsets to what would otherwise be inflationary biases in the
monetary policy process. But these are not usual times—we are in the aftermath of a
financial crisis with stubborn debt overhangs that are weighing on activity. And as
Rogoff himself wrote in a recent piece in the Financial Times, higher inflation could aid
the deleveraging process.11 To quote him: “Any inflation above 2 per cent may seem
anathema to those who still remember the anti-inflation wars of the 1970s and 1980s,
but a once-in-75-year crisis calls for outside-the-box measures.”
Conclusion
Last year about this time economic conditions deteriorated to the point that we
undertook discussions on how to provide further monetary accommodation—and we
ended up with our second round of large scale asset purchases. Now, one year later,
we again find ourselves with a weakened economic outlook and again trying to decide
what further accommodation to provide. I’m sure everyone will agree that we seriously
don’t want to be in this position again at this time next year. I believe that means we
need to take strong action now.
Thanks.
