1. An economy is described by the following equations: Expenditure Sector: Money Sector: S = - 200 + (1/5)YD Ms = 400 TA = (1/8)Y - 40 Md = (1/4)Y + 100 - 5i TR = 60 I = 300 – 10i G = 70 NX = 150 - (1/5)Y Here S is saving; TA is taxes; TR is transfers; I is investment; G is government spending; NX is net exports; Ms is money supply; and Md is money demand. a) (30p) Find the IS and LM equations for this economy. Draw those equations in an IS-LM framework. b) (20p) Find the equilibrium level of output and interest rates. Calculate also the equilibrium values of investment (I), net exports (NX), and money demand (md).
