Q. 1. You are Provided following ISLM information for Mishkinland:

C =100+0.8YD, I=150-20i, G=250, T=250; LM: Ms/P=100, Md/P =Y-80i

(where C=consumption, I =investment, G=government purchases, T=net taxes, i=interest rate in %, Md/P =Demand for money in real terms, Ms/P=real money supply). Note that i is in % in both IS and LM, e.g. if interest rate is 10%, 20i=200.

a) Suppose i=10%.

(i) Calculate equilibrium level of income in goods market if i=10 (in percentage as explained above)

(ii) Calculate equilibrium level of income in money market if i=10 (in percentage as explained above)

b) Is economy in equilibrium? If yes, explain, why. If not, find equilibrium level of Y and i.
