Question

Consider an economy with the following
C = 200 + 0.4(Y − T)
I = 300 − 5000r
T = 0, G = 0
L(rw, Y ) = 250 + 0.06Y − 300r
P = 1
e = 1
rw = 0.09

e is the fixed exchange rate

a. Derive the IS curve and compute equilibrium output and interest rate

b. Derive the LM curve and compute equilibrium money supply

c. Suppose the Central Bank revalues exchange rate from 1 to 0.85. Recalculate the
equilibrium output, interest rate, and money supply

d. Suppose the Central Bank devaluates the exchange rate from 1 to 1.3. Recalculate the
equilibrium output, interest rate, and money supply.
