Abstract

Fundamental models of money always exhibit autarkic equilibria where money has no value. In this paper we propose a simple procedure to select among equilibria in such models. Our procedure unveils a natural mapping between equilibrium behavior and the primitives of the economy, thus offering insights on the conditions under which money emerges as a medium of exchange. Overall, our results favour money over autarky, especially if agents are patient.
