Real money demand in an all currency economy with fixed real output and real interest rate and constant money growth and inflation rates is L = 0.20Y-560i, where Y is real income and i is the nominal interest rate. In equilibrium, real money demand, L, equals real money supply, M/P. Suppose that Y is 600 and the real interest rate, r, is 0.08. a. What inflation rate maximizes seignorage? 0.07 (Round to two decimal places.) [Hint: Use calculus to maximize seignorage, or generate a table to calculate seignorage revenue for every .02 rates of inflation between 0.00 and 0.30.] What is the maximum amount of seignorage revenue? 2.52 (Round to two decimal places.) b. Repeat Part (a) for the case in which Y = 800 and r = 0.10. What inflation rate maximizes seignorage? ☐ (Round to two decimal places.) What is the maximum amount of seignorage revenue? ☐ (Round to two decimal places.)
