Answer:
a. Reduce (or shift leftward) the long-run aggregate supply, since there will be a lower level of employment in the economy.
b. The higher interest rates will lower investment spending and hence the capital stock. A lower capital stock leads to a decrease in long-run aggregate supply.
c. The economy is experiencing greater productivity which increases long-run aggregate supply.
d. Will lead to a more productive work force, increasing long-run aggregate supply.
e. Will lead to more investment spending for capital goods. Increased capital leads to an increase in the long-run aggregate supply.
