An economy is described by the following equations:
Desired consumption Cd = 1275 + 0.5(Y - T) - 200r.
Desired investment Id = 900 - 200r.
Real money demand L = 0.5Y - 200i.
Full-employment output Y = 4600.
Expected inflation π e = 0.
Government Purchases: G = 450
Taxes: T = 450
Money supply M ? 9000
a. Write equations for the IS and LM curves.
b. Calculate the full-employment values of output, the real interest rate, the price level, consumption and investment.
