Basic Economic Concepts unit test
A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

LONG FREE-RESPONSE. Assume the economy of Ardenia is open, has a flexible exchange rate, and is currently in a recession. The unemployment rate is 9 percent while the natural rate of unemployment is 5 percent. The marginal propensity to consume is 0.75, and the recessionary output gap is $600 billion.
Draw a correctly labeled graph of aggregate demand, short-run aggregate supply, and long-run aggregate supply, and show the current short-run equilibrium relative to full-employment output.
Calculate the spending multiplier and the minimum increase in government purchases needed to close the recessionary gap, showing your work.
On your graph from part (a), show the effect of that increase in government purchases on aggregate demand and on the price level.
Assume the increase is financed entirely by government borrowing. Using a correctly labeled graph of the loanable funds market, show the effect on the real interest rate.
Given your answer in part (d), explain the effect on financial capital flows into Ardenia and on the international value of the Ardenian dollar.
Explain the resulting effect on Ardenian net exports.
