We characterize the equilibrium of a search model with a continuum of job and worker types, wage bargaining, free entry of vacancies and on-the-job search. Although on-the-job search reduces the output loss due to frictions, it increases the wage differentials. The decentralized economy with...

We study a search model where workers can send multiple applications to high and low productivity firms. Firms that compete for the same candidate can increase their wage offers as often as they like. We show that there is a unique equilibrium where workers mix between sending both applications...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) "Index for industry concentration". This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

We examine wage competition in a model where identical workers choose the number of jobs to apply for and identical firms simultaneously post a wage. The Nash equilibrium of this game exhibits the following properties: (i) an equilibrium where workers apply for just one job exhibits unemployment...

In The Netherlands, as in many countries: unemployment rates of lower educated workers are higher and more cyclical than unemployment rates of higher educated workers. In this paper we test whether this is caused by the fact that more highly educated individuals occupy simple jobs in cyclical...

We study a search model where workers can send multiple applications to high and low productivity firms. Firms that compete for the same candidate can increase their wage offers as often as they like. We show that there is a unique equilibrium where workers mix between sending both applications...

This paper shows that we can normalize job and worker characteristics so that, without frictions,

This discussion paper has resulted in an article in 'Economica', 2002, 69(273), 21-40.

In this paper we study the allocation of workers over high and low productivity firms in a labor market with coordination frictions. Specifically, we consider a search model where workers can apply to high and or low productivity firms. Firms that compete for the same candidate can increase...
