On the Infinite Welfare Cost of Inflation and Other Second Order Effects
The optimal inflation rate is analyzed in a simple model of intertemporal general equilibrium where agents have an operative bequest motive and taxation is distortionary. Monetary balances are used as a productive input, and agents have perfect foresight. The optimal value of the permanent inflation rate can be approximated by a simple formula. The case in which the growth of aggregate income exceeds the social discount rate is unlikely to be important, and the optimal value of the permanent inflation rate depends on the existence of a short-run trade-oﬀ between unemployment and inflation.
