Abstract

This paper investigates a Trejos-Wright random matching model of money with a consumer take-it-or-leave-it offer and with individual money holdings in the set {0, 1, 2}. It is shown that three kinds of monetary steady state exist generically: (1) pure-strategy full-support steady states, (2) mixed-strategy full-support steady states, and (3) non-full-support steady states. A full-support steady state exists if and only if a non-full-support steady state exists. Stability of these steady states is also studied. Both pure-strategy and mixedstrategy full-support steady states are locally stable. However, non-full-support steady states are unstable.
