Absence-of-Double-Coincidence Models of Money: A Progress Report

Neil Wallace

Winter 1997

This study describes a model built on the long-held view that the use of money as a medium of exchange is the result of an absence of double coincidence of wants. The model can account for two of the most challenging observations facing monetary theory: The disparate short-run and long-run effects of changes in the quantity of money and the coexistence of money and assets with higher rates of return. For both observations, the model's ability to provide a rich analysis depends on little more than the ingredients implicit in the absence-of-double-coincidence view.
