The idea that wages rise relative to alternatives as job seniority accumulates is the foundation of the theory of specific human capital, as well as other widely accepted theories of compensation. The fact that persons with longer job tenures typically earn higher wages tends to support these...

We study the joint processes of job mobility and wage growth among young men drawn from the Longitudinal Employee-Employer Data. Following individuals at three month intervals from their entry into the labor market, we track career patterns of job changing and the evolution of wages for up to 15...

Performance evaluations for workers are typically subjective impressions held by supervisors rather than easily quantifiable measures of output. We argue that perhaps the most important aspect this is that it gives supervisors the opportunity to exercise their personal preference towards their...

A decentralized market theory of investment based on rising supply price is formulated and explained. Asset prices embody all available information in a competitive market and serve as "sufficient statistics" for future market conditions. Construction is determined myopically by marginal cost...

This paper reassesses the evidence on the assimilation and the changing labor market skills of immigrants to the United States. We find strong evidence of labor market assimilation for most immigrant groups. For Asian and Mexican immigrants the first ten years experience in the united States...

We develop an economic framework for valuing improvements to health and life expectancy, based on individuals' willingness to pay. We then apply the framework to past and prospective reductions in mortality risks, both overall and for specific life-threatening diseases. We calculate (i) the...

We consider three questions related to the choice between war in Iraq and a continuation of the pre-war containment policy. First, in terms of military resources, casualties and expenditures for humanitarian assistance and reconstruction, is war more or less costly for the United States than...
