We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their skill. They face a trade-off between match quality and the cost of extended search. This trade-off differs between regions, because search is...

This paper presents a short overview of dynamic models of labor markets with transaction costs. It shows that these models have deeply renewed the understanding of job search, job flows, job creations and destructions, unemployment and wage formation. It argues that this renewal provides a very...

The focus of this paper is on the steady state of a two-sector economy with undirected search where employed and unemployed workers can search for jobs, both within a sector and between the sectors. As in the one-sector model, on-the-job search generates wage dispersion among homogeneous...

This paper studies simultaneous multilateral search (SMS) in over-the-counter (OTC) markets: when searching, an investor contacts several potential counterparties and then trades with the one offering the best quote. Search intensity (how frequently one can search) and search capacity (how many...

In this paper we consider a risk averse worker who is moving back and forth between employment and unemployment; layoffs are random and beyond the worker's influence, while the re-employment chance is directly affected by search effort. We characterize the worker's optimal savings and job-search...

This paper quantifies the importance of non-wage job characteristics to workers by estimating a structural on-the-job search model. The model generalizes the standard search framework by allowing workers to search for jobs based on both wages and job-specific non-wage utility flows. Within the...

In many countries Public Employment Agencies (PEA) offer intermediation services to help as many people as possible to find work by bringing together supply and demand. Using a unique vacancy-level data-set on the number of applicants, we find positive effects of the intermediation services on...

We study active labor market policies (ALMP) in a matching model. ALMPs are modelled as a subsidy to job search. Workers differ in their productivity, and search takes place along an extensive margin. An additional job seeker affects the quality of unemployed workers. As a result, the Hosios...

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...
