We investigate a monetary model in which the centralized market opens once, but the decentralized markets open twice in each period. We show that there may be multiple stationary equilibria.

We study a monetary model in which buyers choose search intensity and prices are considered as given in a decentralized market. We indicate that the Friedman rule may not be optimal.

In a simple search model of money, we study a special kind of memory which gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can choose to have access to a central data base which keeps track of payments made and received. We show that multiple...

This paper extends Shimer's (2005) Mismatch model to allow for endogenous mobility. Rather than work directly in the original model, I use a related framework, the stock-flow matching model (Taylor, 1995; Coles and Muthoo, 1998). One of the contributions of this paper is therefore to compare the...

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...
