Consider the following Keynesian economy: Desired consumption cd=200+0.6(Y-T)- 200r Desired investment Id=300-300r Taxes T=20+0.2Y Government purchases G=152 Net exports NX-150-0.08Y-500r Money demand L=0.5Y 200r Money supply M=924 Full-employment output Y = <= 1000 In this economy, the real interest rate does not devi- ate from the foreign interest rate. a. What are the general equilibrium (that is, long-run) values of output, the real interest rate, consump- tion, investment, net exports, and the price level? b. Starting from full employment, government pur- chases are increased by 60, to 212. What are the effects of this change on output, the real interest rate, consumption, investment, and net exports in the short run? c. Using the same information as provided in part (b), in the long run what would happen to the nominal money supply, the price level, and the real money supply?
