1.Consider an IS/LM model of an economy with the following equations

C = 220 + 0.75Yd

I = 165 - 10i

G = 490 (G bar)

TR = 300 (TR bar)

T = .15Y

Ld = .2Y - 3i

M / P = 550 (M bar, P bar)

(a)Using the above data, derive the equation for the IS curve.

(b)What is the equation for the LM curve?

(c)Calculate the equilibrium level of income and interest rates. Sketch the relevant diagram.

(d)What are the values of the monetary policy multiplier with respect to income and interest rates? If the money supply is reduced by 50, what are the new market-clearing income and interest rate levels? Two Decimal Points
