Suppose that bank reserves (res) are a function of the nominal interest rate (i): res = 0.3 - 3i.The money multiplier is (cu + 1)/(cu + res), where cu is the currency-deposit ratio. Initially, suppose the real interest rate (r) equals 0.03, the expected inflation rate (pe) equals 0.03, and the currency-deposit ratio equals: cu = 0.4 - (10 × pe).The real money demand function is L(Y,i) = 0.8Y - 1500i, where Y is the level of output. The monetary base equals 100. The price level equals 1.0 initially and will not change in the short run, but will adjust in the long run.(a)Calculate the currency-deposit ratio, the reserve-deposit ratio, the money multiplier, the money supply, and the equilibrium level of output. Assume that this level of output equals full-employment output, so
you are assuming that the economy is in general equilibrium with the price level equal to 1.0. Show your work.(b)Suppose financial innovation causes the reserve-deposit ratio to decline to res = 0.2 - 3i. Calculate the new currency-deposit ratio, the reserve-deposit ratio, the money multiplier, the money supply, and the equilibrium level of output in the short run, assuming a Keynesian model with the price level fixed in the short run. Show your work.(c)Calculate the equilibrium price level in the long run. Show your work. What will be an ideal response?
Two firms, Alpha and Beta, produce identical computer hard drives. They have identical costs, and the hard drives they produce are identical. The industry is a natural duopoly
Alpha and Beta enter into a collusive agreement, according to which they split the market equally. If both firms comply with the agreement A) together they will operate in a way indistinguishable from a monopoly. B) the price of a hard drive will be equal to marginal cost. C) each firm will make zero economic profit. D) the oligopoly will produce more hard drives than a profit-maximizing monopoly would produce.
