In cash-in-advance models, necessary and sufficient conditions for the existence of an equilibrium with zero nominal interest rates and Pareto-optimal allocations restrict only the very long-run, or asymptotic, behavior of the money supply. When these asymptotic conditions are satisfied, they...

This paper addresses the problem of multiple equilibria in a model of time-consistent monetary policy. The author suggests that the problem originates in the assumption that agents have rational expectations and proposes several alternative restrictions on expectations that allow the monetary...
