6. Consider the following IS/LM model of a closed economy: Yd = C+1+G C = 300 + 0.75(Y -T) 1 = 600 - 3000r . Y = Ya Ma /P = 0.05(Y/(r + me) ) . MS/P = Md /P G = 195; T = 400 MS = 4800; P = 2 . TTe = 0.035 a. Find the equation that describes the IS curve for this economy. b. Find the equation that describes the LM curve for this economy. c. What are the short run equilibrium values of real aggregate income (Y) and the real interest rate (r) for this economy? d. What happens to the equilibrium value of aggregate income (up or down, and by how much) when autonomous consumption rises from 300 to 400? Hint: it won't increase by (1/(1-0.75))*100. e. Why does your answer in part d differ from the impact predicted by the simple spending multiplier
