The paper studies human capital accumulation over workers' careers in an on the job search setting with heterogenous firms. In renegotiation proof employment con- tracts, more productive firms provide more training. Both general and specific training induce higher wages within jobs, and with...

This article is an idiosyncratic survey of the insider-outsider theory, describing the vision underlying the theory, and evaluating salient contributions to the literature in the light of this vision. We also indicate what appear to have been dead-ends and red herrings in past research. The...

This paper explores the influence of on-the-job training on the employment effect of firing costs. It shows that on-the-job training (generating firm specific skills) causes firing costs to have a contractionary influence on average employment (over the booms and recessions of the business cycle).

Suppose insiders use their market power to push up their wages, while entrants receive their reservation wages. How will employment be affected? In addressing this question, we focus on the role of on-the-job training. We show that an insider wage hike reduces recession-time employment but, in...

Much of the political economy analysis of reform focuses on the conflict of interest between groups that stand to gain or lose from the competing policy proposals. In reality, there is also a lot of disagreement about the working of the policy: in addition to conflicting interests, conflicting...

We construct a simple equilibrium search model in which workers accumulate information about previously met employment contacts. We term the latter search capital. Here search capital (partially) insures workers against adverse shocks. The model provides a theory of job-to-job transitions that...

A matching model in the line of Mortensen and Pissarides (1994) is augmented with a lowskill labor market and firing costs. It is shown that even with flexible wages unemployment is higher among the low-skilled and increases with skill-biased technological change. The two main reasons are that...

When firms decide to post a vacancy they can hire from the pool of unemployed workers or they can poach a worker from another firm. In this paper we show that if there are two different matching processes, one for unemployed workers and another one for job-to-job transitions, then implications...

Many workers believe that personal contacts are crucial for obtaining jobs in high-wage sectors. On the other hand, firms in high-wage sectors report using employee referrals because they help provide screening and monitoring of new employees. This paper develops a matching model that can...

This paper analyzes the effect of labor and product market regulation in a dynamic stochastic equilibrium with search frictions. Modeling multiple-worker firms allows us to distinguish between the exit-and-entry (extensive) margin, and the hiring-and-firing (intensive) margin. We characterize...
