Should the Budget be
Balanced? The Short Run
● Not always.
♦ Attempts to achieve balance during a recession
or an inflationary episode would destabilize the
economy.

Should the Budget be
Balanced? The Short Run
● The Importance of the Policy Mix
♦ The appropriate fiscal policy depends, among
other things, on the current monetary policy
stance.
♦ While a balanced budget may be appropriate
under one monetary policy, a deficit or a
surplus may be appropriate under another.

Surpluses and Deficits: The
Long Run
● More expansionary fiscal policy and tighter
money supply should produce higher real
interest rates and therefore lower
investment, slowing economic growth.
● More restrictive fiscal policy and looser
monetary policy should reduce real interest
rates and hence increase investment and
spur economic growth.

Deficits and Debt:
Terminology and Facts
● Budget Deficit = excess of a government’s
expenditures over its receipts in a period of
time
♦ A flow
● National Debt = total value of government
indebtedness at a moment in time
♦ A stock

Deficits and Debt:
Terminology and Facts
● Some Facts about the National Debt
♦ In absolute terms the debt is large, but as a
proportion of GDP it is less than one half.
♦ Some, but not all, is backed by government
assets.
♦ Before the 1980s, most of the debt was
accumulated in times of war and recession.

Interpreting the Budget
Deficit or Surplus
● Deficit rises in a recession and falls in a
boom even with no change in fiscal policy.
● Structural deficit (or surplus) = what the
deficit (or surplus) would be at full
employment
♦ Portion of the deficit unrelated to the business
cycle
♦ Shows how the deficit is related to government
policy

Interpreting the Budget
Deficit or Surplus
● On-budget Versus Off-budget Surpluses
♦ Overall budget surplus = off-budget surplus +
on-budget surplus
♦ Off-budget surplus = revenues – expenditures
of off-budget items (primarily Social Security
taxes and payments)
♦ On-budget surplus = revenues – expenditures
of on-budget items (most other items)

Bogus Arguments about the
Burden of the Debt
● Our children will be burdened by high
interest payments.
● Repayment of the debt will ruin the nation.
● A nation has a limited capacity to borrow.
Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
Budget Deficits and Inflation
● Deficits   AD
♦ Can cause inflation if economy is strong, since
AS curves slope upward

Budget Deficits and Inflation
● The Monetization Issue
♦ If the Federal Reserve takes no countervailing
actions, an expansionary fiscal policy that
increases the budget deficit will tend to
■  real GDP and prices
■Cause outward shift of the demand curve for
money
■ interest rates

Budget Deficits and Inflation
● The Monetization Issue
♦ If the Fed does not want interest rates to rise
■It can engage in expansionary open-market
operations, that is, purchase more government debt.
■The money supply will then increase.
■The portion of the deficit purchased by the Fed has
been monetized.

Debt, Interest Rates, and
Crowding Out
● Crowding out
♦ Occurs when unemployment is low
♦  deficit   interest rates   investment
+  capital stock
♦ Investment spending is thus crowded out by
government deficit.

Debt, Interest Rates, and
Crowding Out
● Crowding in
♦ Occurs when unemployment is high
♦  deficit   output   savings + 
capacity utilization 

investment +  capital stock
● Crowding-in is likely to dominate in the
short run, crowding-out in the long run.

True Burden of the National
Debt: Slower Growth
● Much of the debt prior to the 1980s was
accrued during recessions, when crowdingin probably occurred.
● Since 1980, high deficits have often
persisted along with high employment,
leading one to think that crowding-out
predominated.
Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
True Burden of the National
Debt: Slower Growth
● The arguments that a large national debt
may lead the nation into bankruptcy, or
unduly burden future generations who have
to make onerous payments of interest and
principal, are mostly bogus.
Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
True Burden of the National
Debt: Slower Growth
● The national debt will be a burden if
♦ It is sold to foreigners.
♦ It is contracted in a fully employed, peacetime
economy.
♦ In the latter case, it will reduce the nation’s
capital stock.
Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
True Burden of the National
Debt: Slower Growth
● Under some circumstances, budget deficits
are appropriate for stabilization-policy
reasons.
● Until the 1980s, the public debt was mostly
contracted as a result of wars and
recessions.
♦ Precisely the circumstances under which the
valid burden-of-the-debt argument does not
apply

True Burden of the National
Debt: Slower Growth
● However, the large deficits of the 1980s and
1990s were not mainly attributable to
recessions, and were therefore worrisome.

?
Issue Revisited: Was Fiscal
Stimulus Warranted in 2001?
● Emergency spending and first phase of tax
cut after September 11th attacks stimulated
economy.
♦ Short-run effects: stimulate AD.
♦ Long-run effects: perhaps crowding out

The Economics and Politics
of the U.S. Budget Deficit
● The deficits of the early 1980s came during
recessions and hence crowding out was not
a serious problem.
● By 1987 the economy was approaching full
employment and hence crowding out was
becoming a problem.
Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
The Economics and Politics
of the U.S. Budget Deficit
● Deficit was eliminated by
♦ raising taxes and
♦ reducing spending;
♦ an expanding economy also produced more tax
revenues.
