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 analyzes the stability of monetary regimes in an economy where fiat money is endogenously created by the government, information about its value is imperfect, and learning is decentralized. We show that monetary stability depends crucially on the speed of information transmission in...

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...

This paper investigates the role of fiat money in decentralized markets, where producers have private information about the quality of the goods they supply. Money is divisible, terms of trade are determined endogenously, and agents can finance their consumption with money or with real...

We use alternative assumptions about the divisibility of goods and money and the ability of agents to use lotteries on money to investigate to what extent the indivisibility of money is the cause for the typically inefficient production and consumption decisions in search-theoretic models of...

Models of the exchange process based on search theory can be used to analyze the features of objects that make them more or less likely to emerge as ``money'' in equilibrium. These models illustrate the trade--off between endogenous acceptability (an equilibrium property) and intrinsic...
