There are also equilibria with genuine fiat currency circulating as the general medium of exchange. We find that… Expand
Money Holdings, Inflation, and Welfare in a Competitive Market
This paper examines an environment where money is essential and agents exchange in perfectly-competitive, Walrasian markets. Agents consume and produce a homogeneous good, but hold money to purchaseExpand
Money and exchange in an economy with spatially differentiated agents
The impact of money supply on the real variables and on utility is an important question in monetary economics. Most previous works study this impact in representative agent economies, often underExpand
Money and the Gains from Trade
This article studies the role of money in environments where in each meeting there is a double coincidence of real wants. Traders who meet at random finance their purchases through currentExpand
A contribution to the pure theory of money
We analyze a general equilibrium model with search frictions and differentiated commodities. Because of the many differentiated commodities, barter is difficult because it requires a doubleExpand
Money as a Unit of Account
We develop a theory that rationalizes the use of a dominant unit of account in an economy. Agents enter into non-contingent contracts with a variety of business partners. Trade unfolds sequentiallyExpand
Individual and Aggregate Money Demands
I construct a model in which money and bond holdings are consistent with individual decisions and aggregate variables such as production and interest rates. The agents are infinitely-lived, haveExpand
The Emergence of Commodity Money as a Medium of Exchange
This paper examines the endogenous emergence of a commodity money in a trading post economy. The commodity money is defined as the common medium of exchange and is determined by the equilibriumExpand

Government Transaction Policy, Media of Exchange, and Prices
Abstract We study government transaction policies in search-theoretic models of money. We model government as a subset of agents, who are subject to the same random matching technology and otherExpand
Monetary Exchange as a Social Convention: Emergence and Stability of an Intermediating Commodity
This paper investigates the stability of monetary exchange equilibria and the conditions necessary for an equilibrium of this type to emerge endogenously. Previous research on money as a medium ofExpand
