The rate of job-to-job transitions is twice as large today as the rate at which workers move from employment to unemployment. I demonstrate that, under plausible specifications, the basic job-ladder model --- the workhorse model of the literature on on-the-job search --- has no chance of...

Labour markets in different regions or countries vary significantly with respect to turnover rates, remuneration practices, investment in general and firm-specific human capital, and the frequency of employee-driven start-ups. Examples include the Silicon Valley versus Route 128 in the US, and...

We study the optimal long-term contract offered to workers when firms are financially constrained in their investment plans. To alleviate the tightness of the financial constraints, firms promise an increasing wage profile to workers, that is, they pay lower wages today in exchange of higher...

What are the sources of rapid wage growth during a worker's early career? To address this question, I construct and estimate a model of strategic wage bargaining with on-the-job search to explore three different components of wages: general human capital, match-specific capital, and outside...

This paper presents a unified treatment of and explanation for the evolution of wages and employment in the U.S. over the last 30 years. Specifically, we account for the pattern of changes in wage inequality, for the increased relative wage and employment of women, for the emergence of the...

This paper introduces a tractable general equilibrium overlapping-generations model of human capital accumulation, and shows that it provides a consistent explanation of several key features of the evolution of the U.S. wage distribution from 1970 to 2000. The framework is based on the...

This paper develops and estimates a search model in which career-specific and firm-specific matches determine job mobility and wage growth. Each worker-firm and worker-career relationship is characterized by a match that evolves stochastically over time. At each period, a worker has three...
