Abstract

We analyze whether or not money can be circulated as a purely transaction medium in the search theory. We obtain the following result: unless the role of a store of value added to the function of money, money does not circulate and the economy degenerates into a barter economy.

Summary

Introduction

There exist two main functions of money: transaction demand for clearing and demand for store of value. Kiyotaki and Wright [1], which is the seminal work on the search money model, insist that money can be circulated solely by the motive of transaction even though it does not operate as a store of value. The visiting opportunities of exchange in a barter economy are more frequent those in a monetary economy This leads us to the following hypothesis: unless money possesses both of the above properties, it is unable to circulate.
