ADVANCED ANALYSIS Assume that the consumption schedule for a private open economy is such that consumption C= 60 +
08Y Assume further that planned investment lo government spending G, and net exports X are independent of the level
of real GDP nd constant at lg 40, G= 0, and Xp= 10. Recall also that, in equilibrium, the real output produced () is equal to
aggregate expenditures: Y= C+lg+ G+ Xp
Instructions: Round your answers to the nearest whole number.

Suppose the Japanese economy has been experiencing slow growth. As a result, the Prime Minister, who thinks John Maynard
Keynes was the greatest economist ever, has decided to increase government spending. The Prime Minister asks the head of
the economic council to determine the increase in government spending necessary to bring the economy to full employment.
Assume there is a GDP gap of 1 trillion yen and the marginal propensity to consume (MPC) is 0.60.
What advice should the head of the economic council give the Prime Minister?
O The recessionary gap is equal to 400 billion yen.
O The inflationary gap is equal to 400 billion yen.
O The recessionary gap is equal to 625 billion yen.
O The inflationary gap is equal to 625 billion yen.
4. Other things equal, what effect will each
of the following changes independently
have on the equilibrium level of real
GDP in a private closed economy?
LO11.5
a. A decline in the real interest rate.
b. An overall decrease in the expected
rate of return on investment.
c. A sizable, sustained increase in stock
prices.
