The next few parts are about Country B, whose government plans to cut taxes by $24 billion
as a measure to fight the current recession. The marginal propensity to consume (MPC) in
Country B is known to be 34. There will be no crowding-out effect.

b) What is the initial effect (in billion dollars) of the tax cut on Country B's aggregate
demand? (The "initial effect" here refers to the effect on AD after only the first round of
increased spending.)
What is the total effect of the tax cut on aggregate demand? Explain why it is different
from the initial effect.
d) How does the total effect of this $24 billion tax cut compare to the total effect of a $24

You are given the following information about aggregate demand at the existing price level for an economy: (1) consumption = $500 billion, (2) investment = $50 billion, (3) government purchases = $100 billion, and (4) exports = $20 billion, imports = $40 billion. If the full-employment level of GDP for this economy is $700 billion. Marginal Propensity to Consume (MPC) of the economy is 0.5. How much government purchases would be closing the GDP-gap here? Explain your answer, and show your calculation.
