FRQ # 2:

Assume the economy of Andersonland is in a long-run equilibrium with full employment. In the short run, nominal wages are fixed.

1. Assume that there is an increase in exports from Andersonland. Explain the effect of higher exports on the following in the short run:

1.  Real GDP
2. Price Level

 

1. Based on your answer in part (a), what is the impact of higher exports on real wages in the short run? Explain.
   
   
2.  As a result of the increase in exports, export-oriented industries in Andersonland increase expenditures on new container ships and equipment.

1. What component of aggregate demand will change? 
2. What is the impact on the long-run aggregate supply? Explain.

 

The foreign purchases effect on aggregate demand suggests that a

A. fall in our domestic price level will increase our imports and reduce our exports, thereby reducing the net exports component of aggregate demand.

B. fall in our domestic price level will decrease our imports and increase our exports, thereby reducing the net exports component of aggregate demand.

C. rise in our domestic price level will increase our imports and reduce our exports, thereby reducing the net exports component of aggregate demand.

D. rise in our domestic price level will decrease our imports and increase our exports, thereby reducing the net exports component of aggregate demand.

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) Assume that the long-run aggregate supply curve is vertical at Y = 3,000 while the short-run aggregate supply curve is horizontal at P = 1.0. The aggregate demand curve is Y = 2(M/P) and M = 1,500.

i) If the economy is initially in long-run equilibrium, what are the values of P and Y?

ii) What is the velocity of money in this economy?

b) Assume that the long-run aggregate supply curve is vertical at Y = 3,000 while the short-run aggregate supply curve is horizontal at P = 1.0. The aggregate demand curve is Y = 3(M/P) and M = 1,000.

i) Suppose a supply shock moves the short-run aggregate supply curve to P=1.5. What are the new short run P and Y? What will be the new long run P and Y?

ii) Suppose that immediately after the supply shock the Federal Reserve Bank wanted to hold output at its long-run level. What level of M would be required? If this level of M were maintained, what would be long-run equilibrium P and Y?

iii) If M increases to 2,000, what are the new short-run values of P and Y?

iv) Once the economy adjusts to long-run equilibrium at M = 2,000, what are P and Y?

c) Use the aggregate demand
