Bivariate duration data frequently arise in economics, biostatistics and other areas. In "bivariate frailty models", dependence between the frailties (i.e., unobserved determinants) induces dependence between the durations. Using notions of quadrant dependence, we study restrictions that this...

This survey is devoted to the modelling and the estimation of reduced-form transition models, which have been extensively used and estimated in labor microeconometrics. The first section contains a general presentation of the statistical modelling of such processes using continuous-time...

The issues of persistence in the observed labour market status of men are investigated using the British Household Panel Survey for the period 1991-97. The paper extends previous work in many directions. In particular, problems of endogenous initial conditions, and unobserved heterogeneity, are...

This paper analyzes the persistence of poverty in Sweden using a hazard rate model based on multiple spells. The model also accounts for unobserved heterogeneity and possibly endogenous initial conditions. We estimate the model on a large representative Swedish panel data set, LINDA, for the...

Based on a multiple spells approach, this paper studies the extent and the composition of chronic poverty in Germany. The results indicate that about one third of cross-sectional poverty in a given year is chronic. The characteristics that are most closely associated with long-term poverty are...

Heterogeneity in the ethnic composition of Germany's immigrant population renders general conclusions on the degree of economic integration difficult. Using a rich longitudinal data-set, this paper tests for differences in economic assimilation profiles of four groups of foreign-born immigrants...

This paper investigates the effects of labour market institutions on wage persistence among young European workers at the beginning of their careers. We use ECHP data from 1995 to 2001 for 13 EU countries and estimate a three-level random intercept probit model that allows for unobserved...
