This study makes use of detailed student-level data from eight cohorts of first-year students at Northwestern University to investigate the relative effects of tenure track/tenured versus non-tenure line faculty on student learning. We focus on classes taken during a student's first term at...

Current and expected job tenure have fallen significantly over the last two decades. Over the same period, traditional defined benefit pensions, designed to reward long tenure, have become steadily less common. This paper uses a contract-theoretic matching model with moral hazard to explain...

This paper studies the efficient agreements about the dependence of workers' earnings on employment, when the employment level is controlled by firms. Under plausible assumptions, such agreements will cause employment to diverge from efficiency as a byproduct of their attempt to mitigate risk....

Performance pay in general amounts to only a small fraction of total pay. In this paper, we show that performance pay is nevertheless important for the level and dynamics of wages over the life cycle because of the incentives it indirectly provides for human capital acquisition and because of...

The extent to which wages rise with the accumulation of seniority(tenure) in a firm after one controls for total labor market experience is a fundamental question about the structure of earnings. A variety of studies have found a large, positive partial effect of tenure on wages. This paper...

We survey two growing bodies of research on firm-level drivers of labor market inequality. The first examines how wages are affected by differences in employer productivity. Studies that focus on firm-specific productivity shocks and control for the non-random sorting of workers to firms...

This paper develops a theoretical framework for analyzing contracting imperfections in long-term employment relationships. We focus chiefly on limited enforceability and limited worker liquidity. Inefficient severance of employment relationships, payment of efficiency wages, the relative...

This study documents a strong inverse relationship between number of pages of labor contracts in effect and the productivity observed in a sample of ten unionized plants. It is argued that this relationship reflects the productivity-inhibiting effects of increases in the number and complexity of...
