Abstract

A trading-post model of money is used to show how exchange rates can be affected by extrinsic uncertainty. With no uncertainty in fundamentals, we demonstrate that there exist equilibria where exchange rates as well as consumption allocations follow a stationary random process. The uctuations are permanent, and they affect economic welfare. These findings also apply when the currency supplies grow at different rates. Then, the only stationary equilibria in which both monies are valued are those with uctuations: the real value of the currencies follow a stationary process, and the average return on the fast-growing currency is lower than that of the slow-growing currency.
