curve?
A) the real balance effect
B) the government policy effect
C) the interest rate effect
D) the international trade effect
3) The interest rate effect occurs when
A) the Federal Reserve increases the money supply, which lowers interest rates and causes
consumers to demand more goods and services.
B) a reduction in the price level lowers the demand for money, and the resulting lower interest
rate causes businesses and others to purchase more goods and services.
C) an increase in the price level reduces the real value of the public's financial assets and causes
them to buy fewer goods and services.
D) All of the above
4) Which of the following accurately describes the real balance effect?
A) If society's aggregate wealth increases for instance, because of a stock market
boom households will demand more goods and services. This will shift the aggregate demand
curve to the right.
B) If the price level increases, this increase in the price level will increase the demand for money
and raise the interest rate. The higher interest rate will lead to increased spending on goods and
services; more real GDP will be demanded at the lower price level.
C) If the price level falls, the real value of society's financial wealth will increase. A portion of
this increased wealth will be spent on goods and services; more real GDP will be demanded at
the lower price level.
D) If you fail to record all your checks, your checkbook will not accurately reflect your real
balance.

Use the following diagram in answering the following question(s).
20) Based on the figure above, suppose an increase in aggregate wealth shifts aggregate demand

1) The aggregate demand curve is downward sloping because of the income and substitution
effects.
2) The three reasons for the downward slope of the AD curve are the real balance effect, the
interest rate effect, and the international trade effect.
3) According to the real balance effect, a reduction in the overall price level will tend to increase
the real incomes of households and cause them to demand more goods and services.
4) The real balance effect explains why the aggregate demand curve tends to shift to the right
when the price level falls.
5) The short-run aggregate supply curve will be upward sloping if some input costs are fixed in
the short run.
6) If a reduction in the price level causes more real output to be demanded, the aggregate demand
curve will shift to the right.

7) The real balance effect describes the increase in the amount of real output that is demanded
when a reduction in the overall price level increases the real value of the public's financial assets.
8) According to the interest rate effect, a reduction in the price level will increase the demand for
money and raise interest rates.
9) An increase in the overall price level should increase the demand for money, raise interest
rates, and lower the amount of real GDP demanded.
10) If a reduction in the overall price level makes U.S. products more attractive relative to
foreign products, more real output will be demanded because of the international trade effect.
11) A reduction in the overall price level in the United States will tend to make U.S. products
more attractive relative to foreign products and shift the AD curve to the right.
12) If households and/or businesses become more optimistic about the future, the AD curve will
tend to shift to the right.
13) An increase in the overall wealth of the society will tend to reduce aggregate demand
because households have satisfied more of their wants.
14) Higher interest rates will tend to shift the AD curve to the right.
15) Increases in the money supply have the same impact as increases in taxes; they both shift the
AD curve to the right.
16) The upward slope of the short-run aggregate supply curve results from the assumption that
all wages and prices are highly flexible.
17) If wages and other input prices immediately adjust upward whenever product prices rise, the
Page 23
short-run aggregate supply curve would be a vertical straight line.
18) When product prices rise, firms find it profitable to expand output because some input prices
are rigid in the short run.
19) If wage rates increase, the aggregate supply curve will shift downward.
20) Increased labor productivity will tend to shift the AS curve to the right.
21) If households and businesses become pessimistic about the future, both the price level and
the level of real GDP will tend to fall.
22) Higher tax rates would tend to raise the overall price level but lower the level of equilibrium
GDP.
23) An increase in the incomes of Japanese consumers would tend to raise the level of U.S.
exports and cause U.S. GDP to rise.
24) Lower income levels in Canada, Mexico, and other trading partners of the United States will
tend to reduce equilibrium GDP in the United States, ceteris paribus.
25) An increase in personal income taxes will shift the short-run AS curve to the right.
26) Higher levels of government spending lead to "cost- push" inflation.
27) Stagflation is caused by reductions in aggregate supply.
28) If the minimum wage is increased, the short-run aggregate supply curve will shift to the left,
reducing equilibrium GDP and raising the overall price level.
29) Bad agricultural harvests can lead to stagflation.
30) Anything that raises labor productivity will tend to shift the short-run AS curve to the left
and raise the overall price level in the economy.
31) If a reduction in aggregate supply leads to stagflation, increasing government spending will
aggravate the inflation problem.
32) Whenever stagflation exists, attempts to reduce the inflation will aggravate unemployment,
and attempts to reduce the unemployment will aggravate inflation.
33) Suppose the economy is in equilibrium at less than full employment. According to the self-
correcting model, in the long run the AD curve will shift to the right and restore full
employment.
34) If unemployment exists, the self-correcting model predicts that it will ultimately be
eliminated by an increase in aggregate supply.
35) According to the self-correcting model, the existence of unemployment ultimately leads to
wage reductions which shift the short-run aggregate supply curve and restore full employment.
36) The economy can never operate beyond potential GDP.
37) The economy cannot sustain an output beyond potential GDP.
38) If the economy is in equilibrium beyond potential GDP, the self-correcting model predicts
that aggregate demand will eventually fall.
Question Status: Previous Edition
39) If the economy is in equilibrium beyond potential, wage rates and input prices will tend to
rise in the long run.
40) Whenever the economy is in equilibrium beyond potential, wage rates and input prices will
ultimately rise, pushing the short-run AS curve to the left.
41) In the self-correcting model of the economy, the mechanism that returns the economy to
potential GDP is adjustments in both aggregate supply and aggregate demand.
42) The self-correcting model relies on adjustments in aggregate supply, not in aggregate
demand.
43) Suppose the economy is in equilibrium at potential GDP. The self-correcting model predicts
that efforts to raise output beyond potential are ultimately offset by rightward shifts of the short-
run aggregate supply curve.
44) Whenever the economy is in equilibrium below potential, unemployment ultimately leads to
falling wages which cause the AD curve to shift to the right and restore full employment and
potential GDP.
45) According to the self-correcting model, the economy can deviate from potential GDP in the
short run but not in the long run.
1) Explain in detail why more real output tends to be demanded at lower price levels than at
higher price levels.
2) Increases in the overall level of wealth will tend to shift the aggregate demand curve to the
right. Reductions in the price level cause the real balance effect which is also related to the level
of wealth but is graphed as movement along a stationary AD curve. Explain how these
phenomena differ and why they are graphed differently.
