How well do alternative labor market theories explain variations in net job creation? According to search-matching theory, job creation in a firm should depend on the availability of workers (unemployment) and on the number of job openings in other firms (congestion). According to efficiency...

How important is imperfect competition in the product market for employment dynamics? To investigate this, we formulate a theoretical model of employment adjustment with imperfect competition in the product market, search frictions, and convex adjustment costs. From this model, we derive a...

This paper analyzes how the aging labor force aþects the unemployment rate at the regional level in Germany. A theoretical model of equilibrium unemployment with spatial labor market interactions is used to study the eþects of age-related changes in job creation and job destruction. Using data...

This paper argues that aging of the labor force affects job creation and job destruction. To analyze this, we extend a standard model of equilibrium unemployment and search in the labor market by the distinction between age specific separation risks and a productivity differential between young...

We incorporate equilibrium unemployment due to imperfect matching into a model of trade in intermediate inputs (Ethier (1982)). Firms are assumed to be price takers and their size is given by technology. Firms enter the market as long as expected profits cover the search cost they incur...

This paper surveys recent work in equilibrium models of labor markets characterized by search and recruitment frictions and by the need to reallocate workers across productive activities. The duration of unemployment and jobs and wage determination are treated as endogenous outcomes of job...

Significant differences in unemployment in Europe have been observed across skill groups, with the least skilled suffering the highest and most persistent unemployment rates. To identify policies alleviating this problem, we study the impact of reductions in employer social security...
