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...

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...

This paper considers estimation of a pure equilibrium search model in which all heterogeneity is endogenous and due to information asymmetries, and of variations that allow better fits to the data. Measurement error and heterogeneity in the productivity levels of firms. The model is fit to a...

The aim of this article is to analyze the survival patterns of a group of family firms which have already spent at least 25 years in the market. To this end, we use the Kaplan-Meier product limit estimator supplemented with qualitative information gathered by direct observation and discussions...

This study addresses the probability of young workers seeking for promotion after vocational training. By applying semi-parametric duration analysis with competing risks to a dataset of 17 youth rosters, each of them winner of either DFB-U19-Bundesliga or DFB-Youth-Cup between 1998/1999 and...

We estimate the impact of the income earned in the host country on return migration of labor migrants from developing countries. We use a three-state correlated competing risks model to account for the strong dependence of labor market status and the income earned. Our analysis is based on...

This paper applies duration and competing risk models to individual-level data on unemployment spells from the 1993-2003 labour force surveys in Italy. We aim to assess whether labour market intervention and regulations introduced in the nineties acted in the expected direction, that is reducing...
