18. If the MPC is 0.80, and if the goal is to increase real GDP by $200 million, then by how much would
government spending have to change to generate this increase in real GDP?
19. Which of the following would be an appropriate discretionary fiscal policy to use when the economy is
in a recession?
Increased government spending.
A balanced-budget reduction in both spending and taxes.
An expansion in the money supply.
20. To combat a recession, Keynesian fiscal policy recommends:
an increase in government spending.

a reduction in both taxes and government spending.
21. Assume the economy is in recession and real GDP is below full employment. The marginal propensity
to consume (MPC) is 0.75, and the government follows Keynesian economics by using expansionary
fiscal policy to increase aggregate demand (total spending). If an increase of $1,000 billion aggregate
demand can restore full employment, the government should:
increase spending by $250 billion.
increase spending by $1,000 billion.
decrease spending by $750 billion.
increase spending by $750 billion.
22. Assume the economy is in recession and real GDP is below full employment. The marginal propensity
to consume (MPC) is 0.50, and the government follows Keynesian economics by using expansionary
fiscal policy to increase aggregate demand (total spending). If an increase of $1,000 billion aggregate
demand can restore full employment, the government should:
increase spending by $250 billion.
increase spending by $1,000 billion.
decrease spending by $500 billion.
increase spending by $500 billion.
23. Assume the economy is in recession and real GDP is below full employment. The marginal propensity
to consume (MPC) is 0.90, and the government follows Keynesian economics by using expansionary
fiscal policy to increase aggregate demand (total spending). If an increase of $1,000 billion aggregate
demand can restore full employment, the government should:
increase spending by $100 billion.
increase spending by $1,000 billion.
decrease spending by $790 billion.
increase spending by $250 billion.
