Consider the following IS-LM model: C= 300+ 0.5YD, I=200+0.3Y-2000i, G=500, T=300

(a) Derive the IS relation. (The relationship of Y and i).

(b) The central bank sets an interest rate of 10 %. How is that decision represented in the equations? (LM relation)

(c) What is the level of real money supply when the interest rate is 10 %? Use the expression: (M/P) = 1.5.Y − 4000.i

(d) Solve for the equilibrium values of C and I.

(e) Suppose that the central bank cuts the interest rate to 8 %. Graphically show this change on IS-LM curves. What is the effect of this policy on Y, I ,C? Is this an expansionary monetary policy or contractionary policy?

(f) Let’s return to the initial situation and assume that the interest rate is set at 10%. Now suppose that taxes increase to 500. Graphically illustrate this change in IS-LM curves. What is the effect of this policy on Y, I ,C? Is this an expansionary fiscal policy or contractionary policy?
