A note on the existence of monetary equilibria in overlapping generations models with storage

Wallace's result for an OG model with nonstochastic storage is extended, by provision of a necessary and sufficient condition for fiat currency to be valued in equilibrium in an OG model with stochastic storage. It is shown that a monetary equilibrium exists if and only if the real rate of return on currency that would obtain in the stationary monetary equilibrium exceeds the risk-free real rate of return that obtains in the nonmonetary equilibrium.
