We compare three pricing mechanisms for monetary economies: bargaining (search equilibrium); price taking (competitive equilibrium); and price posting (competitive search equilibrium). We do this in a framework that, in addition to considering different mechanisms, extends existing work on the...

We study the effects of inflation in models with various trading frictions. The framework is related to recent search-based monetary theory, in that trade takes place periodically in centralized and decentralized markets, but we consider three alternative mechanisms for price formation:...

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...

We construct a search-theoretic model where fiat money coexists with real assets, and all assets can be used as a media of exchange. The terms of trade in bilateral matches are determined by a pairwise Pareto-efficient pricing mechanism. We do not have to appeal to exogenous liquidity...

We study the efficiency of liquidity provision by dealers and the desirability of policy intervention in over-the-counter (OTC) markets during crises. We emphasizes two OTC frictions: finding counterparties takes time, and trade is bilateral and involves bargaining. We model a crisis as a shock...

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

This paper investigates how the degree of trading frictions in asset markets affects portfolio allocations, asset prices, efficiency, and several measures of liquidity, such as execution delays, bid-ask spreads, and trade volumes. To this end, we generalize the search-theoretic model of...
