Suppose that n buyers each want one unit and m sellers each have one or more units of a good. Sellers post prices, and then buyers choose sellers. In symmetric equilibrium, similar sellers all post one price, and buyers randomize. Hence, more or fewer buyers may arrive than a seller can...

We analyze models where agents search for partners to form relationships (employment, marriage, etc.), and may continue searching for different partners while matched. Matched agents are less inclined to search if their match yields more utility and if it is more stable. If one partner searches...

We analyze a two-sided search model in which we assume utility is not perfectly transferable. Except for this assumption the model is standard, yet it generates results that are quite different from those obtained in models with transferable utility. In particular, the model has multiple...

"Search-theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential. However, tractable versions of these models typically need strong assumptions that make them ill-suited for studying monetary policy. We propose a framework based on...
