A new methodology is described which tests between various equilibrium theories of unemployment using matching data. The Paper shows how to correct econometrically for temporal aggregation effects, where the econometrician’s aim is to identify a matching process using data which is recorded...

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...

Societies are characterized by customs governing the allocation of non-market goods such as marital partnerships. We explore how such customs affect the educational investment decisions of young singles and the subsequent joint labour supply decisions of partnered couples. We consider two...

This Paper considers a matching model of heterogeneous workers and jobs, which includes on-the-job search. High-educated workers transitorily accept unskilled jobs and continue to search for skilled jobs. We study the implications of this model for the unemployment rates of high and low-educated...

We show in the framework of a new economic geography model that when labour is heterogenous and productivity depends on the quality of the match between job and worker, trade liberalization may lead to industrial agglomeration and inter-industry trade. The agglomeration force is the improvement...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

A dynamic labour matching economy is presented, in which the unemployed are either entitled to unemployment insurance (UI) or unemployment assistance (UA), and the employees are either eligible for UI or UA upon future separations. Eligibility for UI requires a minimum duration of contributions...

We analyse the efficiency of the labour market outcome in a competitive search equilibrium model with endogenous turnover and endogenous general human capital formation. We show that search frictions do not distort training decisions if firms and their employees are able to coordinate...
