C H A P T E R 9: The Government and Fiscal Policy
Government in the Economy
• Nothing arouses as much controversy as
the role of government in the economy.
• Government can affect the macroeconomy
in two ways:
• Fiscal policy is the manipulation of
government spending and taxation.
• Monetary policy refers to the behavior of the
Federal Reserve regarding the nation’s money
supply.

C H A P T E R 9: The Government and Fiscal Policy
Government in the Economy
• Discretionary fiscal policy refers to
deliberate changes in taxes or spending.
• The government can not control certain
aspects of the economy related to fiscal
policy. For example:
• The government can control tax rates but not
tax revenue. Tax revenue depends on
household income and the size of corporate
profits.
• Government spending depends on government
decisions and the state of the economy.

Net Taxes (T), and Disposable Income (Yd)
• Net taxes are taxes paid by firms
and households to the government
minus transfer payments made to
households by the government.
• Disposable, or after-tax, income
(Yd ) equals total income minus
taxes.
Yd  Y  T

The Budget Deficit
• A government’s budget deficit is the
difference between what it spends (G) and
what it collects in taxes (T) in a given
period:
Budget deficit  G  T
• If G exceeds T, the government must
borrow from the public to finance the
deficit. It does so by selling Treasury
bonds and bills. In this case, a part of
household saving (S) goes to the
government.

Adding Taxes to the
Consumption Function
C  a  bYd
Yd  Y  T
C  a  b( Y  T )
• The aggregate consumption function
is now a function of disposable, or
after-tax, income.

The Tax Multiplier
• A tax cut increases disposable
income, and leads to added
consumption spending. Income will
increase by a multiple of the
decrease in taxes.
• A tax cut has no direct impact on
spending. The multiplier for a
change in taxes is smaller than the
multiplier for a change in government
spending.

The Balanced-Budget Multiplier
• The balanced-budget multiplier is
the ratio of change in the equilibrium
level of output to a change in
government spending where the
change in government spending is
balanced by a change in taxes so as
not to create any deficit.

The Federal Budget
• The federal budget is the budget of
the federal government.
• The difference between the federal
government’s receipts and its
expenditures is the federal surplus
(+) or deficit (-).

The Debt
• The federal debt is the total amount
owed by the federal government. The
debt is the sum of all accumulated
deficits minus surpluses over time.
• Some of the federal debt is held by
the U.S. government itself and some
by private individuals. The privately
held federal debt is the private (nongovernment-owned) portion of the
federal debt.

• Automatic stabilizers are
revenue and expenditure items
in the federal budget that
automatically change with the
state of the economy in such a
way as to stabilize GDP.
