Question

a) Suppose that there are no crowding-out effects and the MPC is 0.8. By how much must the government increase expenditures shift the aggregate-demand curve right $10 billion?

 

b. The model of Long-run Growth, proposes that fiscal policy can have lasting effects on savings, investment, and economic growth. On the other hand, the model of Aggregate Demand-Aggregate Supply suggests that the only long run effect of fiscal policy is an increase in the price level. How could you use the Aggregate Demand and Aggregate Supply model for a more accurate description of the short-run and long-run effects of an increase in government spending? Could you distinguish between different uses of government expenditures to predict their effects on prices and output?
