spending
• Decrease taxes
• increase government
spending and taxes equally

With an MPC of 0.75,
what is the spending
multiplier?
1/MPS = 1/1/4 = 4
7
How much will real
GDP increase by with
an increase in
government spending
of $50 bil?
4 x $50 bil = $200 bil
8
What is the
tax multiplier?
The change in aggregate
demand (total spending)
resulting from an initial
change in taxes
9
What happens when
government cuts
taxes by $50 bil?
The multiplier process is
less because initial
spending increases only by
$38 bil instead of $50 bil
10
What is the formula for
the tax multiplier?
1 – spending multiplier
11
How much does real
GDP increase by with a
cut in taxes of $50 bil?
3 x $50 bil = $150 bil
12
Can we assume that the
MPC will remain fixed?
No, it can change from one
time period to another
13
Can fiscal policy be
used to combat
inflation?
Yes, this would happen
when the economy is
operating in the
Classical or Intermediate
range of the aggregate
supply curve

AD with a cut in G
spending of 25 bil?
-$25 bil x 4 = -$100 bil

18
What is the balanced
budget multiplier?
An equal change in
government spending
and taxes, which
changes aggregate
demand by the amount
of the change in
government spending
19

Federal expenditures and
tax revenues that
automatically change
levels in order to stabilize
an economic expansion
or contraction
20

21
What is a

A budget in which
government revenues
exceed government
expenditures in a given

expenditures exceed
government revenues
in a given time period

A fiscal policy that

27

To achieve long-run

Will an increase in
taxes lead to higher
government revenues?
That depends on
where the economy
is on the Laffer Curve
34
What is the
Laffer Curve?
Puts forth the idea that
increasing taxes from zero
will increase tax revenues
up to a certain point
35
What happens beyond
a certain point?
Tax revenues begin to
decline as the
economic pie begins
to shrink
36
Why does the economic
pie begin to shrink?
Workers have less
incentive to work and
investors have less of
an incentive to invest

Summary
43
Fiscal policy is the use of
government spending, taxes,
and transfer payments for the
purpose of stabilizing the
economy.
44
Discretionary fiscal policy follows
the Keynesian argument that the
federal government should
manipulate aggregate demand in
order to influence the output,
employment, and price levels in
the economy.
45
Discretionary fiscal policy requires
either new legislation to change
government spending or taxes in
order to stabilize the economy.
46
Expansionary fiscal policy is a
deliberate increase in government
spending, a deliberate decrease in
taxes, or some combination of
these two options.
47
Contractionary fiscal policy is a
deliberate decrease in government
spending, a deliberate increase in
taxes, or some combination of
these two options.
48
Using either expansionary or
contractionary fiscal policy, the
government can shift the
aggregate demand curve in
order to combat recession, cool
inflation, or achieve other
macroeconomic goals.
49
Discretionary Fiscal Policies
Expansionary
Contractionary
• Increase government
spending
• Decrease taxes
• Increase government
spending and taxes
equally
• Decrease
government spending
• Increase taxes
• Decrease
government spending
and taxes equally
50
The tax multiplier is the multiplier
by which an initial change in taxes
changes aggregate demand (total
spending) after an infinite number
of spending cycles.
51
Expressed as a formula, the tax
multiplier = 1 - spending multiplier.
52
A balanced budget multiplier is not
neutral. A dollar of government
spending increases real GDP more
than a dollar cut in taxes. Thus, even
though the government does not
spend more than it collects in taxes,
it is still stimulating the economy.
53
Combating recession and inflation
can be accomplished by changing
government spending or taxes.
54
The total change in aggregate
demand from a change in
government spending is equal to
the change in government
spending times the spending
multiplier. The total change in
aggregate demand from a change
in taxes is equal to the change in
taxes times the tax multiplier.

57
A budget surplus occurs when
government revenues exceed
government expenditures.
58
A budget deficit occurs when
government expenditures
exceed government revenues.
59
Automatic stabilizers are
changes in taxes and
government spending that
occur automatically in
response to changes in the
level of real GDP.
60
The business cycle creates
braking power. A budget
surplus slows down an
expanding economy. A
budget deficit reverses a
downturn in the economy.

According to supply-side fiscal
policy, lower taxes encourage
work, saving, and investment,
which shift the aggregate supply
curve rightward. As a result,
output and employment increase
without inflation.
63
The Laffer curve represents the
relationship between the income
tax rate and the amount of
income tax revenue collected by
the government.
