In this paper we study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. We show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search...

This paper 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 current production, the sale of divisible money or both. It is shown that in the absence of valued money if traders...

In this paper we compare production inefficiencies in bilateral meetings generated by two types of trading frictions: double-coincidence frictions and information frictions. For both types of frictions, money enlarges the sets of incentive-feasible allocations relative to barter. In environments...

This paper studies the role of money in asymmetric double coincidence of real wants environments where in each meeting each agent is a consumer of the other agent's production. Traders who meet at random finance their purchases through current production, sale of divisible money, or both. It is...

Many search models of money rely on the double coincidence of real wants problem to generate a role for money and, for the sake of tractability, assume money to be indivisible. In this article, we study the implications of these two assumptions for the formation of the terms of trades and the...

In search-theoretic models of monetary economies, equivalence between money and memory is referred to gift-giving economies. Kocherlakota and Iwai obtain on this basis interesting results. In this paper it is argued that such results should not be interpreted as their authors suggest it. As soon...

In this paper, we consider unemployment equilibria as the result of coordination failures problems. The existence of coordination failures is here based on the realisation of decentralised exchanges. We propose then to investigate the links between the realisation of exchanges and the...

This article addresses the difficulty introducing a new currency into a domestic economy. The aim is to study how a government can influence private agents in their decision to accept, or reject a new fiat currency. Different historical examples teach us that some conditions must be fulfilled...

This paper studies the validity of the Friedman rule in a search model with divisible money and divisible goods where the terms of trades are determined endogenously. We show that ex post bargaining generates a holdup problem similar to the one emphasized in the labour-market literature. Buyers...

This paper considers a monopolist’s supply of outside paper money in a random-matching model with divisible money and divisible goods. When binding supply announcements are feasible, the revenue-maximizing policy is characterized by an initial period where the monopolist initiates a currency...
