How Does a Surplus Affect the Formulation and Conduct of Monetary Policy?
This is a conference on fiscal policy, specifically on how to allocate any potential future
surpluses among debt reduction, tax cuts, and spending increases. The question you and I
might be asking right now is: What is a monetary policymaker doing here? You know, of
course, that I always enjoy visiting with my fellow NABE members. But what contribution
can I make to this important topic?
My assignment is to answer this question: How do the prevailing surplus and, especially,
decisions about the allocation of future potential surpluses affect the formulation and
conduct of monetary policy? The best way to understand the issues involved, in my view, is
through the concept of the policy mix. Using this concept will allow us to focus on the
implications of alternative combinations of monetary and fiscal policies--yielding the same
level of aggregate demand--for the real interest rate, the composition of output, and the
current account balance. And it also will help us understand the key source of the
interdependence of monetary and fiscal policy decisions.
In planning my remarks today, I intended first to discuss the analytics and the politics of the
policy mix and then to illustrate the power of the analysis by using it to explain some of the
important features of our current experience. For example, the swing in the structural budget
balance clearly helps to explain the increase in the national saving rate and the high level of
investment relative to GDP in this expansion. However, other important features of recent
macroeconomic experience--specifically the absence of a large decline in real interest rates
and the significant deterioration in the current account balance--appear at least superficially
inconsistent with the predictions from the standard analytics.
One problem, I believe, is the assumption that the recent dramatic swing in the structural
budget balance has been driven exclusively by policy. Perhaps even more important are
other developments that have affected real interest rates and the current account balance
over the same period. I could sum up these problems by noting that "ceteris" aren't always
"paribus."
I conclude by discussing the implications for monetary policy of options for the allocation
of the "potential" surplus. Because these options involve alternative policies, the standard
framework should provide appropriate guidance about projected outcomes--ceteris paribus,
of course. I focus on two ways in which fiscal policy choices could affect monetary policy.
First, fiscal policy choices will affect the interest rate consistent with full employment and
price stability. Second, a gradual reduction and ultimate retirement of the federal

government debt would require changes in the way monetary policy is implemented.
The Analytics of the Policy Mix
The policy mix is a very useful device for understanding the interaction of monetary and
fiscal policies. There are infinite combinations of monetary and fiscal policies that yield the
same level of aggregate demand. The different combinations result in different outcomes for
the level of real interest rates, the composition of output, and the current account balance.
The composition of output at a given time has implications for the level of output over time.
So the policy mix has quite important implications for macroeconomic performance.
The policy mix can be easily represented in a simple IS-LM diagram, shown in figure 1 (6
KB). This illustrates a simple model of macroeconomic general equilibrium. The IS curve
shows the combinations of interest rate (R) and output (Y) consistent with equilibrium in the
output market. The LM curve shows the combinations of interest rate and output consistent
with equilibrium in the market for money. The intersection of the curve shows the unique
combination of the interest rate and output consistent with equilibrium in all markets
simultaneously.
Let's start from a simple case in which the level of capacity is given at a moment in time and
the intersection of IS and LM curves determines the prevailing level of aggregate demand.
As long as this intersection occurs at or to the left of the capacity limit, potential output
(Y*), it determines the level of output, at least in the short run. I will assume that the
intersection takes place at potential output, so that the outcome is consistent with the broad
objectives of monetary policy: price stability and full employment. Evaluating alternative
fiscal policies at an unchanged level of output--and specifically at potential output--also
allows us to abstract from cyclical changes in the deficit and thereby to focus exclusively on
changes in the structural budget balance.
The position of the LM curve is determined in part by the stance of monetary policy. I have
drawn the conventional upward sloping LM curve predicated on a constant money stock. In
this case, we could view the level of the money stock as being adjusted by open market
operations to be consistent with the Federal Reserve's target for the interest rate.
Alternatively, we could draw the LM curve as a horizontal line at the prevailing interest rate
target set by the FOMC. The position of the IS curve is determined in part by fiscal policy,
including the level of discretionary spending and benefit and tax rates. The latter rates also
affect the slope of the IS curve, but I will abstract from that detail.
In Figure 1 (6 KB), I depict two of the infinite number of combinations of IS and LM curves
that intersect at potential output--the intersection at B corresponding to a looser fiscal and
tighter monetary policy than the intersection at A.
The first question I want to answer is, What difference does it make where the intersection
of IS and LM curves occurs for a given level of output? The answer is, It makes a world of
difference. A combination of tighter fiscal and looser monetary policy (point A compared
with point B in figure 1 (6 KB)) implies a lower interest rate, a higher share of investment
(and, in general, of interest-sensitive components of spending) in GDP, a lower value of the
dollar, and a higher level of net exports and hence of the current account surplus. Therefore,
by selecting a particular policy mix, policymakers can affect the amount of capital formation
and the current account balance.

The above simple version of the IS-LM model does not begin to do justice to the topic. In
more sophisticated models, we would see explicitly the long-run increase in output
associated with a shift in the composition of output today toward more investment. In
addition, more sophisticated models would also show explicitly the increase in the exchange
rate and the associated decline in the current account balance in response to a policy mix
that resulted in higher real interest rates. Finally, more sophisticated models could also take
into account a second dimension of fiscal policy changes. Not only do changes in tax rates
and spending affect aggregate demand, they can also affect aggregate supply, for example,
when they alter after-tax wage rates and after-tax rates of return to saving and investment.
The effect of any change in the policy mix will also be affected by supply-side incentives
incorporated in the fiscal part of the mix.
The Politics of the Policy Mix: Does Monetary Policy Respond to Fiscal Policy?
How does the choice about the policy mix get made? An interesting question! No, we do not
have a joint committee on the policy mix that considers the benefits of alternative mixes and
reaches a judgment. The policy mix is determined by sequential decisionmaking, subject to
an understanding of the structure of the economy and of the likely responses of the other
policymakers to one's policy actions.
In my view, the process works as follows. The Administration and the Congress together
make decisions that determine the fiscal part of the policy mix. Over the last 20 years, these
decisions generally have been based on considerations that have more to do with long-run
objectives such as promotion of higher longer-term growth, than with short-run stabilization.
Making these decisions takes considerable time because of the dynamics of the annual
budget process and the legislative process. The current year's decisions are incorporated and
the following years' decisions are anticipated in the fiscal policy assumptions underlying the
Federal Reserve's forecast, extending out a year or two. The Federal Reserve then sets its
policy to achieve the broad objectives assigned to it, specifically, price stability and full
employment. Fiscal decisions are, in turn, affected by budget forecasts that are partly
contingent on monetary policy assumptions.
In effect, fiscal policymakers make the fundamental decision about the policy mix.
Monetary policymakers smooth the transition to the new equilibrium, by minimizing the
effect on output relative to full employment and on prices. Because monetary policy adjusts
continuously to changes in the economy, including those resulting from fiscal policy, it
makes sense to think that fiscal policy decisions are made first and monetary policy
decisions are conditional on the fiscal decisions.
So does this mean that monetary policy responds directly to fiscal policy actions? I believe it
is more accurate to say that the Fed's response is indirect. That is, monetary policy responds
to changes in fiscal policy in much the same way that it responds to other influences on the
economy, such as equity prices, exchange rates, or the demand for U.S. exports due to
changed growth prospects abroad. Each and all of these developments affect both the
macroeconomic developments and the forecast that drive adjustments in monetary policy in
pursuit of full employment and price stability.
It is also important not to overstate the role monetary policy plays in shaping the policy mix.
Indeed, the fiscal policy decision uniquely determines the policy mix. In terms of our
diagram, the game is fundamentally over when the fiscal decision pins down the intersection
of the IS curve and the vertical line at full employment. The only question remaining is how

the LM curve will come to intersect at the same point.
One possibility, of course, is that the Federal Reserve adjusts its open market operations to
move the interest rate to this point. In a regime in which the Fed implements policy by
choosing a target for the money stock, either the money stock could be adjusted to move the
LM curve to this point, or price flexibility would ultimately get the job done, with the
emphasis on the ultimately. The role of active monetary policy is to avoid the need for price
flexibility--that is, to prevent the fiscal decision from either temporarily lowering output
below its full employment level or permanently increasing prices.
In an interest-rate regime, holding the funds rate unchanged following a shift in the IS curve
would result in an escalating disequilibrium. For this reason, an interest-rate regime has to
be modeled in terms of a policy reaction function. Under a plausible policy rule--for
example, utilizing actual or forecast output gaps and inflation rates--the interest rate would
be reset over time until it was consistent with the intersection of the IS curve and the vertical
line at potential output and price stability.
The message of such an interest rate rule is that monetary policy responds only indirectly to
fiscal policy. That is, the rule specifies the adjustment of the interest rate to changes in
output and prices (the indirect approach), not the adjustment to changes in tax rates or
spending (as would be the case in a direct approach). However, if we look at the reduced
form equation for the now endogenous monetary policy instrument, we shall, to be sure,
find--lurking on the right-hand side--the exogenous components of the fiscal policy
decision--the level of discretionary spending and the benefit and tax rates. That the response
may be indirect does not make it any less systematic.
In the "real world," of course, many factors besides fiscal policy are likely to be affecting
inflation and output. So we may rarely actually observe the interrelationships implied by the
analytics of the policy mix. That is, ceteris are rarely paribus, which brings me to my next
topic.
Comparing the Theoretical Prediction to Recent Experience
The swing from budget deficit to surplus has been much more dramatic than was expected
when the fiscal year 1994 budget was adopted. Such a dramatic swing in the budget balance
might have been expected to yield a particularly dramatic confirmation of the predictions of
the analytic model, in the form of a sharp decline in real interest rates and a significant
improvement in the current account balance.
In fact, during the period of a dramatic swing in the budget balance, real interest rates have
not declined, and the current account balance has significantly deteriorated. If you hadn't
already suspected, we are about to find out that the real world is always more complex, and
much more interesting, than our simple models. Two explanations for this conflict between
theoretical prediction and recent experience are possible. First, the preceding analysis is
fundamentally flawed. Second, it is at least incomplete. I will take the second route and
argue that the problem was that ceteris were not paribus in this episode.
Ceteris paribus, of course, means "all other things being equal." In our models, it is a way of
examining the effect of one shock, holding constant all other shocks that could effect the
variables in question. In class and in model simulations, we can always impose ceteris
paribus. Indeed, ceteris paribus was implicitly assumed all the way through the section on

analytics. In the real world, we do not have this option. In addition, in the analytics, by
holding output fixed at potential, we abstracted from the effect of cyclical influences on the
budget balance, on interest rates, and on the current account.
The key to getting the right answer in the analysis is to identify correctly the multiple shocks
that induced the swing in the ratio of deficit to GDP and that affected the real interest rate
and current account, as well as to take into account the effect of the cyclical developments. I
assumed in the analytics of the policy mix that that any non-cyclical change in the deficit
was due to a change in policy--some combination of increases in tax rates and cutbacks in
government spending. Indeed, specific fiscal policy actions make this characterization
appear qualitatively correct. But to explain the real-world outcomes we also have to allow
for the role of other influences, specifically structural change.
A portion of the swing in the budget balance was of course due to the cyclical upswing. In
our analytics, we were able to control for this by holding the level of output constant at
potential output. But to apply this to our dynamic economy, we have to allow for uncertainty
about the level of potential output at a given time and the growth in potential output over
time.
A unique feature of the recent cyclical experience has been the divergence between the
cyclical strength of the U.S. economy and that of its major trading partners--that is, the weak
expansion in Europe, the long period of stagnation in Japan, and the crises among many
emerging market economies from late 1997 through 1998. This divergence in cyclical
strength was accompanied for several years during this episode by a persistent appreciation
of the dollar, further contributing to a deterioration in the current account.
However, the more serious problem with the application of the conventional framework is
the failure to account for structural change, specifically a decline in the non-accelerating
inflation rate of unemployment (NAIRU) and an increase in trend growth. The decline in the
NAIRU, for example, would raise the equilibrium level of output and increase imports,
worsening the current account balance. More rapid trend income growth would also increase
the growth of imports and hence cause a deterioration in the current account. In addition,
higher trend productivity growth, driven by an increase in the profitability of investing in
new technology, would raise the equilibrium real interest rate and encourage capital flows to
the United States to take advantage of higher returns on capital. This in turn would lead to
an appreciation of the dollar, further augmenting the current account deficit. Once again, it
appears that the increase in the economy's trend rate of productivity growth is playing a
starring role in our explanation of recent macroeconomic developments.
In discussing the interaction between the swing in the federal budget and the increase in the
productivity trend, I have focused on how the latter may have offset the tendency of the
former to lower real interest rates. But, of course, the interaction works in both directions.
The increase in the equilibrium real interest rate, expected as a result of an increase in the
productivity trend, is also a ceteris paribus result. It depends critically on the assumed fiscal
policy rule. For example, if tax rates are constant and government spending remains a
constant share of GDP, then the higher productivity trend will, in general, yield a higher
equilibrium real interest rate. However, if real (or nominal) government spending is held
constant, the surplus will rise over time as a share of GDP, putting downward pressure on
the equilibrium real rate, offsetting, at least in part, the effect on the real rate of the higher
trend productivity.

The Surplus Conundrum and the Policy Mix
Although the discussion of the policy mix did not fully explain recent economic
performance, I still believe it offers important insights into the alternative options for
dealing with the current and projected surpluses, at least if ceteris really turn out to be
paribus. But the recent episode underscores the difficulty of actually predicting real interest
rates and the current account when unknowable shocks will surely intervene along the way.
My assignment is not to evaluate how much confidence we should have in projected
surpluses or to assess the merits of alternative allocations of projected surpluses. Rather, my
assignment is to connect fiscal and monetary policy decisions. I have emphasized the value
of evaluating fiscal policy options in models that incorporate reasonable monetary policy
reaction functions. Doing so builds in the indirect response of monetary policy to fiscal
policy changes, consistent with the logic of the policy mix. This is, in effect, the approach I
followed my discussion of the analytics of the policy mix by assuming that monetary policy
is reset--albeit indirectly--in response to a change in fiscal policy.
Retaining the projected non-social security surplus in the CBO baseline is one alternative.
The other options involve increased fiscal stimulus and, as a result, will be accompanied,
ceteris paribus, by a higher equilibrium real interest rate in the long run. They would also
likely result in a lower share of investment in output and a higher current account deficit
than the option that preserves higher surpluses. The specific outcomes will depend on the
details, especially on the nature of supply-side incentives in any spending or tax changes.
Ceteris paribus, monetary policy--run off a sensible reaction function--will end up validating
the higher equilibrium real interest rate, to keep prices from accelerating indefinitely.
The Implications of Debt Retirement for Monetary Policy Operations
One additional consequence of the choice among these options is that preserving the
surpluses would lead to a gradual decline in and ultimately the retirement of the federal
government debt. The prospects for such an outcome depend, of course, on the realized
growth rate of income and hence tax revenue and one's assumption about the starting base of
expenditures and the appropriate baseline for its rate of growth. I have already noted that
such an outcome should not be viewed as a foregone conclusion. And, even if the Treasury
debt were to be fully retired, that outcome would be likely to be transitory. Once the baby
boomers begin to retire, the social security trust fund will be progressively run down, and at
some point, the overall budget will likely move from surplus to deficit again.
Today, Treasury securities account for the bulk of the Federal Reserve's portfolio of assets.
Treasury securities are a convenient and natural choice for the Federal Reserve's portfolio
because they pose no credit risk and because the depth and liquidity of the Treasury market
facilitate open market operations. Although the Treasury market has been the traditional
vehicle for monetary policy operations in recent decades, the Federal Reserve Act provides
authority for the Federal Reserve to purchase a fairly wide range of other assets--including
obligations of federal agencies, certain obligations of state and local governments, foreign
exchange, and sovereign debt. Moreover, the Federal Reserve often supplies reserves
through repurchase transactions in addition to outright purchases. If the Treasury market
became less liquid, we could substitute longer-term RPs against eligible collateral for some
outright purchases of securities. If the existing classes of assets that the Federal Reserve is
authorized to purchase or to acquire were deemed too narrow, we could pursue technical
changes in the Federal Reserve Act to authorize transactions with a broader range of assets.
Still another option would be to expand the role of the discount window in the provision of

reserves to the banking system. The key point is that declining Treasury debt does not pose
any insurmountable long-term problem for the Federal Reserve. There would, of course, be
transitional issues as monetary policy operations adapted. But we surely maintain the
effectiveness of our monetary policy operations. So a decision about whether or not to hold
on to the surpluses and ultimately retire the government debt should not be affected by any
concern that this option might undermine the effectiveness of monetary policy.
Some have been concerned that the Federal Reserve and the Treasury might be working at
cross purposes today to the extent that reductions in the Treasury debt supply have lead to
declines in longer-term Treasury rates at a time when monetary policy is aiming to slow the
pace of economic activity to a more sustainable rate. To date, the main impact of Treasury
operations and debt management prospects has been on longer-term Treasury rates, with
only a small spillover effect on the financial variables that affect private spending decisions-short- and longer-term private interest rates, equity prices, and exchange rates. To the
extent that Treasury debt management operations affect the private interest rates or other
financial conditions that matter for private spending decisions, the FOMC can always adjust
its policy settings as appropriate to achieve its objectives.
Conclusion
In debt management as well as other fiscal policy decisions, the Administration and the
Congress should make the decisions that are in the best long-run interest of the economy.
Monetary policy cannot affect the long-run consequences of such policy decisions, but it can
adjust to smooth the economy's transition to the new equilibrium. Monetary and fiscal
policies should therefore be thought of as working as partners, rather than in competition
with each other. In addition, decisions about the allocation of the government surplus or
about debt management operations should not be limited by any concern that a gradual
decline in or even ultimate retirement of the government debt would undermine the ability
of monetary policy to achieve the broad objectives that the Congress has assigned to it.
