"Real Indeterminacy of Stationary Equilibria in Matching Models with Media of Exchange"

Abstract

In this paper, it is shown that real indeterminacy of stationary equilibria generically arises in most matching models with perfectly divisible media of exchange. In other words, the real indeterminacy follows from the condition for stationarity of holdings of media of exchange. Moreover, we present a new technique to prove the existence of stationary equilibria; especially, it is applicable to the case that both money and goods are perfectly divisible.
