We analyze the implications of multiple applications by job seekers for the microfoundations of the matching function. We emphasize a coordination failure caused by multiple applications, namely, that firms can waste resources processing applicants who are ultimately hired elsewhere.

In many economies, there is substantial economic activity in the informal sector, beyond the reach of government policy. Labor market policies, which by definition apply only to the formal sector, can have important spillover effects on the informal sector. The relative sizes of the informal and...

We show that in a search/matching model with endogenous participation in which workers are heterogeneous with respect to market productivity, satisfying the Hosios rule leads to excessive vacancy creation. The reason is that the marginal worker does not internalize the effect of his or her...

We construct a bilateral search model of the housing market in which agents differ in their flow rewards while searching. Buyers and sellers enter the market with high flow rewards, but move at a Poisson rate to a state with low flow rewards if they do not transact in the meantime. We...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

Do people move to cities because of marriage market considerations? In cities singles can meet more potential partners than in rural areas. Singles are therefore prepared to pay a premium in terms of higher housing prices. Once married, the marriage market benefits disappear while the housing...
