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...

In this paper I explore optimal employment contract design in a random search framework, where workers search on and off the job for employment opportunities similar to that of Lentz (2010) and Bagger and Lentz (2013). The worker determines the frequency by which employment opportunities arrive...

We analyze the contractual relation between workers and their employers when there is nominal risk. The key feature of the problem is that the consumption deflator is random and observed sometime after the effort is exerted. The worker's effort is not observable, and to induce the agent to work,...

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...

In this paper we analyze the problem of whether and/or when to replace a leader (agent) when no monetary rewards are available, and it is the leader's competence rather than effort that is being evaluated. The only decisions that the leader takes over time are whether to undertake risky but...

We provide new estimates of the return to job seniority using data similar to that used by Abraham and Farber (1987), Altonji and Shakotko (1987) and Topel (1991) as well as a new PSID sample. Topel's use of a wage and a tenure that refer to different years, his use of the Current Population...

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...
