Reflect on the major topics of this unit and answer any three of the problems at the end of chapter seven in the text book. Be sure to consider alternative perspectives as you answer the problems.

1. Explain how the following changes in aggregate demand or short-run aggregate supply, other things held unchanged, are likely to affect the level of total output and the price level in the short run. a. An increase in aggregate demand b. A decrease in aggregate demand c. An increase in short-run aggregate supply d. A reduction in short-run aggregate supply

2. Explain why a change in one component of aggregate demand will cause the aggregate demand curve to shift by a multiple of the initial change.

3. Use the model of aggregate demand and short-run aggregate supply to explain how each of the following would affect real GDP and the price level in the short run. a. An increase in government purchases

b. A reduction in nominal wages

c. A major improvement in technology

d. A reduction in net exports

4. How would an increase in the supply of labor affect the natural level of employment and potential output? How would it affect the real wage, the level of real GDP, and the price level in the short run? How would it affect long-run aggregate supply? What kind of gaps would be created?

5. Give three reasons for the downward slope of the aggregate demand curve.

6. “When the price level falls, people’s wealth increases. When wealth increases, the real volume of consumption increases. Therefore, a decrease in the price level will cause the aggregate demand curve to shift to the right.” Do you agree? Explain.

7. Suppose the economy has a recessionary gap. We know that if we do nothing, the economy will close the gap on its own. Alternatively, we could arrange for an increase in aggregate demand (say, by increasing government spending) to close the gap. How would your views about the degree of price stickiness in the economy influence your views on whether such a policy would be desirable?

Explanation / Answer

Only 1 question answered per post.

1. a.An increase in aggregate demand in the short run, increases the output level over and above the level achieved with full employment and effects upward pressure on prices.
b. Decrease in aggregate demand in the short run, decreases the prices and output as there will be increase in resource supply leading to decrease in the resource price.
c. Increase in aggregate supply curve in short run, shifts the curve to right, with increased output caused by increase in resources and at lower prices.
d. Decrease in aggregate supply curve, indicates decrease in resources leading to less output, with increased resource prices.
