This document discusses key concepts related to fiscal policy. It defines discretionary fiscal policy as the deliberate use of changes in government spending and taxes to stabilize the economy. Expansionary fiscal policy includes increasing spending, decreasing taxes, or both. Contractionary policy refers to decreasing spending, increasing taxes, or both. The spending multiplier is defined as 1 divided by 1 minus the marginal propensity to consume. Automatic stabilizers and concepts like the budget, surplus, deficit and Laffer Curve are also explained.

Summary

44. 44
Fiscal policy is the use of
government spending, taxes,
and transfer payments for the
purpose of stabilizing the
economy.

45. 45
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.

46. 46
Discretionary fiscal policy requires
either new legislation to change
government spending or taxes in
order to stabilize the economy.

47. 47
Expansionary fiscal policy is a
deliberate increase in government
spending, a deliberate decrease in
taxes, or some combination of
these two options.

48. 48
Contractionary fiscal policy is a
deliberate decrease in government
spending, a deliberate increase in
taxes, or some combination of
these two options.

49. 49
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.

50. 50
• Increase government
spending
• Decrease taxes
• Increase government
spending and taxes
equally
Expansionary Contractionary
Discretionary Fiscal Policies
• Decrease
government spending
• Increase taxes
• Decrease
government spending
and taxes equally

51. 51
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.

52. 52
Expressed as a formula, the tax
multiplier = 1 - spending multiplier.

53. 53
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.

54. 54
Combating recession and inflation
can be accomplished by changing
government spending or taxes.

55. 55
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.

56. 56

price level

58. 58
A budget surplus occurs when
government revenues exceed
government expenditures.

59. 59
A budget deficit occurs when
government expenditures
exceed government revenues.

60. 60
Automatic stabilizers are
changes in taxes and
government spending that
occur automatically in
response to changes in the
level of real GDP.

61. 61
The business cycle creates
braking power. A budget
surplus slows down an
expanding economy. A
budget deficit reverses a
downturn in the economy.

63. 63
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.

64. 64
The Laffer curve represents the
relationship between the income
tax rate and the amount of
income tax revenue collected by
the government.

1. Contractionary fiscal policy is deliberate
government action to influence aggregate
demand and the level of real GDP through
a. expanding and contracting the money
supply.
b. encouraging business to expand or
contract investment.
c. regulation of net exports.
d. decreasing government spending or
increasing taxes.
D. The money supply is under control of
the Federal Reserve and not Congress.

67. 67
2. The spending multiplier is defined as
a. 1 / (1 - marginal propensity to
consume).
b. 1 / (marginal propensity to
consume)
c. 1 / (1 - marginal propensity to save).
d. 1 / (marginal propensity to consume
+ marginal propensity to save.
A. The spending multiplier is also
defined as 1/MPS.

68. 68
3. If the marginal propensity to consume
is 0.60, the value of the spending
multiplier is
a. 0.4
b. 0.6
c. 1.5
d. 2.5.
D. Spending multiplier = 1 / (1 - MPC) =
1 / (1 - 0.60) = 1 / 40/100 = 5 / 2 = 2.5

69. 69
4. Assume the economy is in recession and real
GDP is below full employment. The marginal
propensity to consume is 0.80, and the
government increases spending by $500 billion.
As a result, aggregate demand will rise by
a. zero.
b. $2,500 billion.
c. more than $2,500 billion.
d. less than $2,500 billion.
B. Change in aggregate demand (Y) = initial
change in government spending (G) x spending
multiplier.
Spending multiplier = 1 / 1 - MPC) = 1 / (1 - 0.80) = 1
/ 20/100 = 5
Y = $500 billion x 5
Y = $2,500 billion

70. 70
5. Mathematically, the value of the tax
multiplier in terms of the marginal
propensity to consume (MPC) is given by
the formula
a. MPC  1.
b. (MPC  1) MPC
c. 1 / MPC
d. 1  [1 / 1  MPC)].
D. The tax multiplier is also stated as Tax
multiplier = 1 - spending multiplier.

71. 71
6. Assume the marginal propensity to
consume (MPC) is 0.75 and the
government increases taxes by $250
billion. The aggregate demand curve will
shift to the
a. left by $1,000 billion.
b. right by $1,000 billion.
c. left by $750 billion
d. right by $750 billion.
A. The tax multiplier is -3 (1 - spending
multiplier) and -3 times $250 equals a $750
billion decrease. The movement is left
because consumers have less money to
spend.

72. 72
7. If no fiscal policy changes are made, suppose
the current aggregate demand curve will
increase horizontally by $1,000 billion and cause
inflation. If the marginal propensity to consume
is 0.80, federal policy-makers could follow
Keynesian economics and restrain inflation by
a. decreasing government spending by $200
billion.
b. decreasing taxes by $100.
c. decreasing taxes by $1,000 billion.
A. Change in government spending (G) x spending
multiplier = change in aggregate demand,
rewritten:
G = change in aggregate demand / spending
multiplier
Spending multiplier = 1 / (1-MPC) = 1 / (1-0.80) = 1 /
20/100 = 5
G = -$1,000/5, G = -$200 billion.

73. 73
8. If no fiscal policy changes are implemented,
suppose the future aggregate demand curve will
exceed the current aggregate demand curve by
$500 billion at any level of prices. Assuming the
marginal propensity to consume is 0.80, this
increase in aggregate demand could be
prevented by
a. increasing government spending by $500
billion.
b. increasing government spending by $140
billion.
c. decreasing taxes by $40 billion.
d. increasing taxes by $125 billion.
D. Change in taxes (T) x tax multiplier = change in
aggregate demand, rewritten:
Tax multiplier = 1 - spending multiplier
Spending multiplier = 1 / (1-MPC) = 1 / 1-0.80) = 1 / 20/100 = 5
Tax multiplier = 1 - 5 = -4, T = $600 billion/5, T = -$200
billion

74. 74
9. Suppose inflation is a threat because the
current aggregate demand curve will
increase by $600 billion at any price level.
If the marginal propensity to consume is
0.75, federal policy-makers could follow
Keynesian economics and restrain
inflation by
a. decreasing taxes by $600 billion.
b. decreasing transfer payments by $200
billion.
c. increasing taxes by $200 billion.
d. increasing government spending by
$150 billion.
C. 3 x $200 billion = $600 billion.

75. 75
10. If no fiscal policy changes are implemented,
suppose the aggregate demand curve will
exceed the current aggregate demand curve by
$900 billion at any level of prices. Assuming the
marginal propensity to consume is 0.90, this
increase in aggregate demand could be
prevented by
a. increasing government spending by $500
billion.
b. increasing government spending by $140
billion.
c. decreasing taxes by $40 billion.
d. increasing taxes by $100 billion.
D. The multiplier here is 10 (1 divided by 1/10 =
10). If taxes are increased by $100 billion
spending will go down by $90 billion. Ten
times $90 equals $900.

76. 76
11. Which of the following is not an
automatic stabilizer?
a. Defense spending.
b. Unemployment compensation benefits.
c. Personal income taxes.
d. Welfare payments.
A. Defense spending does not
automatically change levels as real GDP
changes.

77. 77
12. Supply-side economics is most
closely associated with
a. Karl Marx.
b. John Maynard Keynes.
c. Milton Friedman.
d. Ronald Reagan.
D. The most familiar supply-side
economic policy of the Reagan
administration was the tax cuts
implemented in 1981.

78. 78
13. Which of the following statements is true?
a. A reduction in tax rates along the
downward-sloping portion of the Laffer
curve would increase tax revenues.
b. According to supply-side fiscal policy,
lower tax rates would shift the aggregate
demand curve to the right, expanding the
economy and creating some inflation.
