Several studies show that employees with firm-specific skills are more likely to be covered by employer-sponsored pension schemes than workers with general skills. Therefore it can be expected that workers with firm-specific skills retire earlier. This paper tests this prediction using US data...

Skill-biased technical change is usually interpreted in terms of the efficiency parameters ofskilled and unskilled labor. This implies that the relative productivity of skilled workerschanges proportionally in all tasks. In contrast, we argue that technical changes also affectthe curvature of...

This paper provides new evidence on the nature of occupational differences in unemployment dynamics, which is relevant for the debate between the structural or hysteresis hypotheses. We develop a procedure that permits us to test for the presence of a structural break at unknown date[...]

This paper reviews the literature on two-sided atomeless assignment models of workers to tasks. Using simple parametric examples, the fundamental differences between the comparative advantage and the scale of operations models are illustrated. Holding the distributions of abilities and tasks and...
