The paper contributes to the debate on top performance in research productivity, its persistence over time, and the impact of gender. It uses a panel data set comprising the publications of all biomedical and exact scientists at the University of Leuven in the period 1992 to 2001. We find that...

Although military conscription was widespread during most of the past century, credible evidence on the effects of mandatory service is limited. We provide new evidence on the long-term effects of peacetime conscription, using longitudinal data for Portuguese men born in 1967. These men were...

OECD labor markets have become more “polarized” with employment in the middle of the skill distribution falling relative to the top and (in recent years) also the bottom of the skill distribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partly due to...

The paper contributes to the debate on cumulative advantage effects in academic research by examining top performance in research and its persistence over time, using a panel dataset comprising the publications of biomedical and exact scientists at the KU Leuven in the period 1992-2001. We study...

We provide new evidence on the long-term impacts of peacetime conscription, using longitudinal data for Portuguese men born in 1967. These men were inducted at age 21, allowing us to use preconscription wages to control for ability differences between conscripts and nonconscripts. We find a...

This paper describes and explains some of the principal trends in the wage and skill distribution in recent decades. Increases in wage inequality started in the US and UK at the end of the 1970s, but are now widespread. A good fraction of this inequality trend is due to technology-related...
