2. Suppose that in the Australian economy mpc = 0.7, mpm = 0.1, and t = 0.2; and that the following figures are in billions of Australian dollars: C = 1950 1 = 800 G = 900 EX = 380 IM = 250 T=220 TRP = 210 Recall: Y = [1/(1-mpc+(mpc*t)+mpm)]*[ C - mpc*T + mpc*TRP + I +G + EX -IM ] A) Assume that C and I decrease by $250 billion and $75 billion, respectively, due to higher interest rates, and that the government increases TRP by $40 billion. By how much will the Australian real GDP change (AYAUS)? Be specific about the sign of the change. Show your work and BOX IN your answer. [5 points]
