5. Problems and Applications Q11 Consider an economy described by the following equations: Y=C+I+G C-120+0.8x (Y-T) I 500-50 XT G=150 T=125 where Y is GDP, C is consumption, I is investment, G is government purchases, T is taxes, and r is the interest rate. If the economy were at full employment (that is, at the natural rate of output), GDP would be $2,850. Identify the equation(s) each of the following statements describes. Check all that apply. Statement C I G T It is an autonomous amount, independent of other factors. 0 0 0 0 It is a function of disposable income. 0 0 0 0 It depends on the interest rate. 0 0 The marginal propensity to consume in this economy is Suppose the central bank's policy is to adjust the money supply to maintain the interest rate at 3%, so = 3. When the interest rate is 3%, GDP is $ GDP at an interest rate of 3% is the full-employment level. Assuming no change in monetary policy, (Note: Assume that this change in fiscal policy has no crowding-out effect.) in government purchases by $ would restore GDP to the full-employment level. Assuming no change in fiscal policy, in the interest rate by % would restore GDP to the full-employment level.
