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.

This paper uses a simple model to explore the effects of 'increasing demand risk' on business fixed investment. We show that within a putty-clay framework an increase in demand uncertainty can be expected to have two countervailing effects. On the one hand increasing risk tends to induce a firm...

This paper examines the problem of nonexistence of equilibrium in a simple search model with asymmetric information. A pure-strategy, symmetric Nash equilibrium fails to exist because adverse selection arising from steady-state considerations causes a nonconcavity in the payoff function.

In this paper we extend models of "search market equilibrium" to incorporate general equilibrium considerations. The model we treat is one with a single product market and a single labor market. Imperfectly informed individuals follow optimal strategies in searching for a suitably low price and...
