a) Derrve the IS relation
b) Derive the LM relation.
c) Solve for equilibrium real output (Y*).
d) Solve for the equilibrium interest rate (1).
e) Solve for the equilibrium values of C and I, and verify the value you obtained for Y by
adding C, L and G.
f) Now suppose that the money supply increases to M/P =1,840. Solve for Y, i, c, and T, and
describe in words the effects of an expansionary monetary policy.
g) Set M/P equal to its initial value of 1,600. Now suppose that government spending
increases to G= 400. Summarize the effects of an expansionary fiscal policy on Y, i. C.
h) The expansionary fiscal policy in part (g) have resulted in large budget deficit (T - G =
200 - 400 = -200). Suggest a policy mix to decrease fiscal deficit to achieve a balanced
