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...

There are two facts about the world that we take as given: First the "law of one price" is false -- one can find many different prices for what appears to be, beyond reasonable doubt, the same good. Second, prices are set in nominal terms and appear, beyond reasonable doubt, to be sticky -- some...

We integrate search theory into an equilibrium framework in a new way and argue that the result is a simple but powerful tool for understanding many issues related to bilateral matching. We assume for much of what we do that utility is less than perfectly transferable. This turns out to generate...

There is much discussion of the relationships between crime, inequality, and unemployment. We construct a model where all three are endogenous. We find that introducing crime into otherwise standard models of labor markets has several interesting implications. For example, it can lead to wage...

We extend simple search-theoretic models of crime, unemployment and inequality to incorporate on-the-job search. This is valuable because, although the simple models can be used to illustrate some important points concerning the economics of crime, on-the-job search models are more relevant...

We extend simple search models of crime, unemployment, and inequality to incorporate on-the-job search. This is valuable because, although simple models are useful, on-the-job search models are more interesting theoretically and more relevant empirically. We characterize the wage distribution,...

The authors analyze markets where each of n buyers wants to buy one unit and each of m sellers wants to sell one or more units of an indivisible good. Sellers first set prices, then buyers choose which sellers to visit. There are equilibria where each buyer visits sellers at random and faces a...
