We study dynamic task allocation when providers' expertise evolves endogenously through training. We characterize optimal assignment protocols and compare them to discretionary procedures, where it is the clients who select their service providers. Our results indicate that welfare gains from...

We look at how the arrival of an invention affects wage returns and probability of moving out of employment for white- and blue-collar coworkers of the inventor. First results suggest that older workers are hurt by the arrival of an invention. This negative effect disappears when we control for...

This paper analyzes economic behavior and the effects of training and income support policies in the low wage labor market for women. The opportunity set takes account of nonlinearities and discontinuities associated with career interruption, part-time work, and government programs. There are...

This study explores the existence of a net union premium and of the extent of rationing by quality of the resulting excess supply. The net union premium was estimated by relating changes in wages to changes in union status of the same worker in longitudinal panels (NLS and MID), and by two...

This paper is an econometric analysis of the on-the-job training (OJT) decisions of a group of white American males during 1975. The data are obtained from the Panel Study of Income Dynamics, which asked a very careful series of questions concerning the individual's OJT status. Each individual's...

There is substantial evidence from the literature on individual wage determination that length of service to the firm is an important determinant of earnings and thus of labor productivity, holding constant employee at-tributes such as age, sex, and education. Earnings growth associated with...

We investigate learning at the workplace. To do so, we use German administrative data that contain information on the entire workforce of a sample of establishments. We document that having more highly paid coworkers is strongly associated with future wage growth, particularly if those workers...

This paper estimates the dynamic returns to job training. We posit a dynamic-discrete choice model of sequential training participation, where choices and earnings depend on observed and unobserved characteristics.We define treatment effects, including policy relevant parameters, and link them...

Why has the college wage premium risen rapidly in the United States since the 1980s, but not in European economies such as Germany? We argue that differences in employment protection can account for much of the gap. We develop a model where firms and workers make relationship-specific...

Exploiting variation in welfare reform across states and over time and using relevant comparison groups, this study estimates the effects of welfare reform on an important source of human capital acquisition among women at risk for relying on welfare: vocational education and training. The...
