ECON 1P92 Lecture Notes - Shortage, Potential Output, Longrun

1. In the long run, when prices are perfectly flexible:

a. aggregate supply is vertical and a market economy is self-correcting.

b. a market economy cannot self-correct.

c. government will be required to set prices to maintain equilibrium.

d. changes in aggregate demand cause equilibrium real GDP to change.

2. An increase in household wealth when the SRAS curve is upward sloping:

a. leads to an increase in the price level but has no impact on real GDP

b. has no impact on the price level but leads to an increase in real GDP

c. leads to an increase in both the price level and real GDP

d. has no impact on the price level or real GDP

3. In the long run, continued increases in aggregate demand not matched by similar increases in aggregate supply will cause:

a. an increase in the full-employment level of real GDP

b. a recessionary gap

c. a decrease in the price level

d. an increase in the price level

4. The vertical long-run aggregate supply curve implies that:

a. changes in aggregate demand will not affect the price level

b. the short-run aggregate supply curve is also vertical

c. natural or full-employment real GDP does not depend on the price level, in the long run

d. natural or full-employment real GDP is the same as the equilibrium real GDP in the short run

5. A rightward shift of the long-run aggregate supply curve illustrates:

a. economic growth

b. a recessionary gap

c. an inflationary gap

d. a decrease in natural real GDP

6. When the economy is in a recessionary gap

a. there is a surplus of labor

b. there is a shortage of labor

c. it is producing a real GDP level that is greater than natural real GDP

d. the unemployment rate is less than the natural unemployment rate

7. If the actual unemployment rate is less than the natural unemployment rate:

a. a recessionary gap exists and wages are likely to rise

b. an inflationary gap exists and wages are likely to rise

c. a recessionary gap exists and wages are likely to fall

d. an inflationary gap exists and wages are likely to fall

8. An economy in long-run equilibrium is producing:

a. a level of real GDP that is greater than its natural real GDP

b. where both the price level and real output are maximized

c. a level of real GDP equal to its natural real GDP

d. in the vertical range of aggregate demand.

a. Suppose the economy is operating at its full employment level output. Does it mean that the unemployment rate is ZERO? Explain.

b. What is the difference between a recessionary gap and an inflationary gap? Explain

c. If the actual economy is operating below its full-employment long run equilibrium, then an inflationary gap will develop. If your answer yes, explain. If your answer is no, explain

1. As prices fall, the value of people's existing assets rises and people increase expenditures. This occurs as a result of the:

a. international effect.

b. interest rate effect.

c. money wealth effect.

d. multiplier effect.

2. An increase in aggregate demand, in the long run, will change:

a. both output and the price level.

b. neither output nor the price level.

c. the price level but not output.

d. output but not the price level.

3. A change in which of the following will shift the long-run aggregate supply curve?

a. The price level

b. Aggregate demand

c. Available resources

d. Sales or excise taxes

4. If potential output exceeds actual output, the economy:

a. is experiencing a recessionary gap.

b. is in neither a short-run nor long-run equilibrium.

c. may be in a long-run equilibrium but is not in short-run equilibrium.

d. is experiencing an inflationary gap.

5. Keynes believed the economy was:

a. always moving toward potential income.

b. always at potential income.

c. always moving away from potential income.

d. fluctuating around potential income.
