Monetary Equilibria over an Infinite Horizon.

Abstract

Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and a sequentially complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances. A public authority, inheriting a strictly positive public debt, raises revenue from taxes and seignorage. Competitive equilibria exist, under mild solvency conditions. But, for a fixed path of rates of interest, there is a nontrivial multiplicity of equilibrium paths of prices of commodities. Determinacy requires that, subject to no-arbitrage and in addition to rates of interest, the prices of state-contingent revenues be somehow determined.money; equilibrium; indeterminacy; monetary policy; fiscal policy
