This paper presents an analysis of the failure and completion rates of graduate students in economics at three universities in The Netherlands. We find that an indicator of the research productivity of the supervisor is an important determinant of the completion and dropout rates. However, this...

In this paper we define and estimate measures of labor market frictions using data on job durations. We compare different estimation methods and different types of data. We propose and apply an unconditional inference method that can be applied to aggregate duration data. It does not require...

Ridder and Woutersen (2003) have shown that under a weak condition on the baseline hazard there exist root-N consistent estimators of the parameters in a semiparametric Mixed Proportional Hazard model with a parametric baseline hazard and unspecified distribution of the unobserved heterogeneity....

Adult height, as a marker of childhood health, has recently become a focus in understanding the relationship between childhood health and health outcomes at older ages. However, measured height of the older individuals is contaminated by height shrinkage from aging. Height shrinkage, in turn may...

For various reasons the relationship between age and productivity is a matter of policy concern. I present new empirical research showing how productivity is affected by age. I study age effects at the individual level by analyzing data on running and publishing in economic journals. Furthermore...

We analyze the determinants of reading literacy, mathematical skills and science skills of young immigrant children in the Netherlands. We find that these are affected by age at immigration and whether or not one of the parents is native Dutch.

Intergenerational immigrant integration is central to the economic growth and social development of many countries whose populations comprise a substantial share of the children and grandchildren of immigrants. In addition to basic demographics, relevant economic theories and institutional...

This paper presents an analysis of labour market dynamics, in particular of flows in the labour market and how they interact and affect the evolution of unemployment rates and participation rates, the two main indicators of labour market performance. Our analysis has two special features. First,...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...
