In a large class of hazard models with proportional unobserved heterogeneity, the distribution of the heterogeneity among survivors converges to a gamma distribution. This convergence is often rapid. We derive this result as a general result for exponential mixtures and explore its implications...

We evaluate the effect of active labour market programs on the duration of unemployment in a reward or punish system. In Switzerland, unemployment benefits are conditional upon program attendance after 7 months of unemployment duration. In the evaluation we allow for selectivity affecting the...

The vocational employment training program is the most ambitious and expensive training program in Sweden and a cornerstone of labor market policy. We analyze its causal effects on the individual transition rate from unemployment to employment by exploiting variation in the timing of treatment...

Probably not. First, allowing the probabilities of the states of the economy to differ from their sample frequencies, the Consumption-CAPM is still rejected in both U.S. and international data. Second, the recorded world disasters are too small to rationalize the puzzle unless one assumes that...

This paper investigates whether cannabis use affects physical and mental health. To do so, information on prime aged individuals living in Amsterdam in 1994 is used. Dutch data offer a clear advantage in estimating the health impacts of cannabis use because the legal status of cannabis in the...

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...

There are large spatial disparities in unemployment durations across the 1,300 municipalities in the Paris region (Ile-de-France). In order to characterize these imbalances, we estimate a proportional hazard model stratified by municipality on an exhaustive dataset of all unemployment spells...

In this paper, we examine the disincentive effects of the public employment service on the search effort of unemployed workers and on their exit rate from unemployment. For that purpose, we specify a structural search model with fixed and variable costs of search in which unemployed workers...

The potential duration of benefits is generally viewed as an important determinant of unemployment duration. This Paper evaluates a unique policy change that prolonged entitlement to regular unemployment benefits from 30 weeks to a maximum of 209 weeks for elderly individuals in certain regions...

The transition from centrally planned to market economy involves a process of massive occupational change that has been largely neglected in the literature. This paper investigates this process using data from the 1995 Estonian Labour Force Survey. We find that between 35 and 50 percent of wage...
