Determine whether each of the following, other things held constant, would lead to an increase, a decrease, or no change in long-run aggregate supply:

Question

a. An improvement in technology

b. A permanent decrease in the size of the capital stock

c. An increase in the actual price level

d. An increase in the expected price level

e. A permanent increase in the size of the labor force

Take a shot, I or someone else will critique your thinking. Hint: two of the answers, i believe, are movements along the long-run aggregate supply curve rather than a shift in the curve.
