Suppose that there are no crowding-out effects and the MPC is .9. By how much must the government increase expenditures to shift the aggregate demand curve to the right by $10 billion?

Step 1
The multiplier effect describes how an initial change in spending leads to a larger change in national income. The formula for the multiplier (k) is given by: \[ k = \frac{1}{1 - MPC} \] where MPC is the marginal propensity to consume. Show more…

Assume that the MPC is 0.8. Assume that there is a multiplier effect and that the total crowding-out effect is $8 billion. How will an increase in government purchases of $10 billion shift aggregate demand?

If the MPC is 0.80 and there are no crowding-out or accelerator effects, then an initial increase in aggregate demand of $100 billion will eventually shift the aggregate demand curve to the right by $80 billion. $125 billion. $500 billion. $800 billion.

Suppose that a certain country has an MPC of .9 and a real GDP of 400 billion dollar. If its investment spending decreases by 4 billion dollar, what will be its new level of real GDP?
