Existence of Equilibria in Matching Models of Money: A New Technique

This paper develops a new technique for proving the existence and indeterminacy of monetary equilibria in money search models with divisible money. Our technique is substantially simpler than standard constructive proofs in the literature. This paper is based on the second half of Kamiya and Shimizu (2002). We are very grateful to the associate editor and an anonymous referee of this journal for their very detailed suggestions and comments.
