An economy has neither imports nor income taxes. The MPC is 0.75 and the real GDP is $120 billion. The government increases expenditures by $4
billion.
The multiplier is _____ and the change in real GDP from the increase in government expenditures is _____ billion.
Ramey's estimate of the short-run "multiplier effect" of government purchases on GDP (i.e., dY/dG) is closest to
a. -1
b. 0
c. +2
d. +1
e. -2
In the economy of Keynesian Island, autonomous consumption expenditure is $50 million, and the marginal propensity to consume is 0.8. Investment is $160 million, government expenditure is $190 million, and net taxes are $250 million. Investment, government purchases, and taxes are constant—they do not vary with income. The island does not trade with the rest of the world.
If the government increases its purchases by $200 million, what will be the change in the economy's equilibrium real GDP? Show the change on the graph as well.
