This paper develops a general equilibrium model in which households face fixed costs associated with searching for a new supplier of consumption goods. These search costs provide firms with some monopoly power over their existing customers and generate the kind of customer flow dynamics first...

This paper characterizes optimal monetary policy in the context of a general equilibrium model with optimizing agents and staggered price setting. Starting from a steady state with positive inflation, a rapid disinflation is desirable when announcements of future monetary policy are fully...

This paper embeds two key ideas about the nature of financial innovation taken from the empirical literature into a familiar equilibrium monetary model. It provides formal support for several alternative econometric specifications for money demand that attempt to capture the effects of financial...

This paper presents a stochastic version of Townsend's turnpike model in which the aggregate endowment is distributed randomly between two sets of agents and in which agents of each type are allowed to remain at a trading post for multiple periods. Agents use money as a means of exchange when...
