As 2017 begins, the US economy is in the middle of a boom,
or at least a boomlet. The official unemployment rate is at or below its target level, stock market indicators
are hitting all-time highs, and the Fed is starting to get serious about raising
interest rates. All this is reflects the expectation of an orgy of tax
cutting and infrastructure spending by the incoming Trump administration and a
new Republican Congress. If such a turn in policy comes
to pass, will it be a good thing, or too much of a good thing?
Too much, in my opinion.
Republicans like to portray themselves as the party of fiscal
responsibility, but their record says otherwise. In practice, GOP budget policy
so far this century has been consistently procyclical—expansionary
when it should show constraint, contractionary when it should support a weak
economy. All signs point to another procyclical episode in the making.
Patterns of Fiscal Policy
To set the stage, here is a little background on patterns of fiscal policy—the good,
the bad, and the ugly. Economists of all political
views show surprisingly broad agreement on the general principles. Good fiscal
policy should moderate the business cycle (or at least not make it worse) and should
do so in a way that avoids unsustainable increases in public debt. Bad policy
amplifies booms and busts. Ugly policy can lead to major crises.
First, some essential terms and concepts:
- The output gap is the difference between the economy’s level of output at the moment and the output it would produce if it were operating at full employment. During a slump, the output gap is negative. During a boom, it is positive.
- The actual balance of the government budget is the current value of government expenditures minus revenues . This is the headline deficit (-) or surplus (+) that politicians usually talk about.
- Economists pay more attention to the structural balance— that is, the surplus or deficit that would prevail if the output gap were zero.
- To estimate the structural balance, economists adjust the actual balance by removing the effects of automatic stabilizers. Automatic stabilizers are budget components like unemployment benefits and income tax revenues that vary automatically (that is, without action by policymakers) as the economy expands and contracts over the business cycle.
The structural balance is useful because it isolates changes
in policy, such as tax cuts or new spending programs. Changes in the actual
balance, on the other hand, represent the combined effect of changes in policy
and changes in the state of the economy. Even if there are no changes in policy
at all, automatic stabilizers cause the actual balance to move toward surplus
when the economy expands and toward deficit when it contracts.
We can use these concepts to identify three patterns of
fiscal policy. The simplest is a “cyclically neutral” policy that holds the
structural balance at zero throughout the business cycle. Holding the
structural balance constant does not prohibit all policy changes. Rather, it requires
that any spending changes be financed by equal changes in revenue, or equal but
opposite changes in spending elsewhere in the budget.
Under a cyclically neutral
policy, the relationship of our three key variables over the business
cycle would look like this:
Starting from zero, the output gap becomes positive as the
economy expands. Automatic stabilizers come into play as rising incomes push up
tax revenues and a strong labor market reduces outlays for unemployment
compensation, food stamps, and other transfer payments. As a result, the actual
balance of the budget moves into surplus. Once the cycle passes its peak and
the economy begins to contract, the actual budget surplus decreases. As the
output gap turns negative, automatic stabilizers operate in reverse and the
actual budget balance moves into deficit.
Cyclically neutral fiscal policy is good policy. It doesn’t
completely tame the business cycle, but it does allow automatic stabilizers to
moderate excessive booms and busts. If the target for the structural balance is
set at or near zero, the national debt will remain within sustainable levels. (Although
we set the structural balance target at zero in our example, the optimal target
may, in practice, be a little higher or lower, as
explained in this
earlier post.) For a number of years, Chile,
by some measures the most prosperous
country in Latin America, has used a version of cyclically neutral fiscal policy to good effect.
An even better pattern of policy is one that is actively countercyclical,
while holding the structural balance at or close to zero on average over the
business cycle, like this:
In this pattern, policymakers use spending cuts or tax
increases to move the structural balance toward surplus as the economy begins
to expand,. As automatic stabilizers come into play, the actual balance moves
even more strongly toward surplus. The combined effect of automatic stabilizers
and active policy changes ensures that the economy does not overheat. During a
downturn, policymakers enact stimulus measures in the form of tax cuts and
spending increases to move the structural balance toward deficit. Those
measures, together with the operation of automatic stabilizers, prevent the contraction
from turning into a deep recession.
Sweden
has used countercyclical policy with the budget balanced over the business
cycle since the early 1990s. That approach has allowed the country to prosper
while deeply reducing its once-excessive deficits and debt. However, such a
policy is not feasible for every country. For one thing, it requires good
forecasting and long-range policy planning, since countercyclical policy
changes work best when they are made somewhat in advance of cyclical turning
points. If action is delayed until the
economy overheats or falls into a deep slump, it can be too late to apply
effective restraint or stimulus. Furthermore,
combining short-run countercyclical measures with long-run structural balance year
after year requires a degree of political maturity, discipline, and agreement
across party lines that not all countries have.
Finally, we can use the same kind of diagram to illustrate
bad fiscal policy—policy that is procyclical, making the business cycle more
severe rather than moderating it. One variant of bad policy looks like this:
This variant of procyclical policy holds the actual budget
balance constant over the business cycle. When the economy enters an expansion,
policymakers increase spending or cut taxes, thus neutralizing the operation of
automatic stabilizers. That moves the structural balance toward deficit but
holds the actual balance at zero. When the economy enters a recession, higher tax
rates and discretionary expenditure cuts move the structural balance toward
surplus to offset the tendency of automatic stabilizers to move the actual
balance toward deficit. On balance, this policy pattern stimulates the economy
during booms, causing it to overheat, and then subjects it to measures that
turn moderate recessions into deep slumps.
The kind of policy illustrated in this diagram has not
actually been used in the United States, but it has been championed, in the
form of a balanced
budget amendment, by many
Congressional conservatives. A balanced
budget rule that focused on the structural balance might make sense, but one
that aims at the actual budget balance, as all proposals introduced in Congress
to date have been, is one of the worst ideas in the GOP playbook.
To be sure, even annual balancing of the actual budget would
not be the worst possible kind of fiscal policy. A really ugly policy pattern
would be one that combined procyclical stimulus during expansions
and austerity during recessions with deficits deep enough, on average
over the business cycle, to threaten the sustainability of the public debt.
Back to the real
world
It is time, now, to see what US fiscal policy looks like in
the real world. The next chart shows output gaps and deficits for the US
federal budget since the start of the twenty-first century, drawn for easy
comparison with the theoretical patterns discussed above.
The century began with the mild recession of 2001, which
lasted just eight months and followed the record-setting 120-month expansion of
the 1990s. The incoming administration of George W. Bush reacted swiftly with
the Economic Growth and Tax Reconciliation Act of 2001, which sharply cut tax
rates. In its timing, the 2001 tax cut
was countercyclical, but very large in relation to the relatively shallow
recession.
A further round of tax cuts followed in 2003, after
Republicans gained control of both houses of Congress. At the same time, the
invasion of Iraq and a continuation of the war in Afghanistan added to
federal expenditures. The combined effect of these measures swung the
structural balance from a surplus of 1.6 percent of GDP in 2000 to a deficit of
2.9 percent by 2004. Meanwhile, the business cycle was well into its expansion
phase. Taken as a whole, then, fiscal policy in these years was procyclical.
The years from 2005 to 2007 saw a moderation of the fiscal
stimulus. The structural balance moved from a deficit of 2.9 percent of GDP in
2004 to a deficit of just 1 percent by 2007. The result was mildly
countercyclical, although perhaps insufficiently so, in view of the housing
boom. The Federal debt continued to grow
in absolute terms throughout the Bush years, although it declined slightly as a
percentage of GDP in 2006 and 2007.
In 2008, the Bush administration reacted with commendable
quickness to the onset of recession and the developing financial crisis. In
February 2008, Congress passed a stimulus package that included both business
tax cuts and one-time tax rebates for individuals. That was followed by a much larger stimulus package early in
2009, soon after Barack Obama’s inauguration. In combination, these actions
were strongly countercyclical, with the structural balance moving from a
deficit of just 1 percent in 2007 to a deficit of 7.3 percent by 2009.
In mid-2009, boosted by these actions, the economy began to
recover. The federal budget continued to provide significant fiscal stimulus
for the next two years. Things changed, however, after the Democrats lost control of
the House in 2011. A series of fiscal high-wire acts followed, including a debt
ceiling crisis in 2011, a government shutdown in October 2013, and the “fiscal
cliff” crisis at the end of that year. These crises led to a series of tax
increases and spending cuts that brought an end to the stimulus. The policy change was marked
by a decrease in the structural deficit from 6.1 percent of GDP in 2011 to just
1.6 percent by 2014.
The burst of fiscal austerity came at a time when GDP was
still far below potential. In 2011, the output gap was still -4.25 percent of
GDP and the unemployment rate was over 8 percent. The premature withdrawal of
stimulus was widely regarded as procyclical, especially by the Federal Reserve, which was doing its best to speed the
recovery with its policy of quantitative
easing. Fed Chairman Ben Bernanke repeatedly warned
Congress that tight fiscal policy was undermining the pace of recovery and
making the Fed’s work much harder.
Ironically, in 2016, just as the economy was struggling back
toward something close to full employment, fiscal policy began to ease again.
The structural deficit increased from 1.6 percent of GDP in 2015 to 2.4 percent
in 2016. Projections
released by the Congressional Budget Office in August of that year, before the
election, already pointed to continued procyclical increases in the structural
deficit and a disappearance of the output gap by 2018.
As we enter 2017, with a new president and a new Congress,
those earlier projections are beginning to look too moderate. Everyone is
talking about more tax cuts, more infrastructure spending, and increases in the
military budget. The dashed lines at the far right of the above chart reflect
my adjustment of the output gap and deficit projections by +0.25 percentage
points for 2017 and 1.0 percentage points for 2018.
The bottom line:
Little to be proud of
This tour of fiscal policy in the twenty-first century shows
little to be proud of. True, the government, under both Republican and
Democratic administrations, was able to muster strong countercyclical responses
to the 2001 and 2007-2009 recessions. However, procyclical policy
predominates. Lingering and unneeded stimulus in the early years of the
expansion that followed the 2001 recession undoubtedly contributed to the housing bubble and the
financial crisis of 2008. Premature austerity after 2011 slowed the recovery
from the Great Recession, despite extraordinary measures by the Fed to provide
monetary stimulus.
Is the stage now set for the strongest dose of procyclical
fiscal policy yet? That is a very real possibility. Tax cut fever is in the
air. Despite the rhetoric of fiscal hawks, Congressional Republicans have, in
the past, found it hard to resist demands to spend the revenue generated by
economic expansions rather than using it to pay own the debt. A bad record of
fiscal policy may be about to turn ugly.
