Let the real demand for money be Y L=1 0.2R e Its level is parameterized by 1, which is affected by multiple factors, explored below. a. Compute the equilibrating interest rate, in terms of the log of Y,R,M,P and parameter 1 b. If Y rises by 10% to Y'= 1.1Y, or 1 rises by 1% to l'= 1.17, all else equal, the equilibrium interest rate changes by approximately what percentage? Also, sketch the shifting curve(s). c. If MP rises by 10% to M'/ P'= 1.1(M / P), all else equal, the equilibrium interest rate changes by approximately what percentage? Also, sketch the shifting curve(s). d. In the 1st quarter of 2020, money supply was at M = 15.36 (M2 measured in $trillions), price level at P = .708, baseline real demand for money at 1 = 1, and GDP at Y = 21.538 (in $trillions, annual rate). What was the equilibrium interest rate, as a percentage to two decimals? (We interpreted it as the rate on Baa corporate bonds; ICE BofA.)
