Using data from the German Socio-Economic Panel Study (GSOEP), we analyze whether necessity entrepreneurs differ from opportunity entrepreneurs in terms of self-employment duration. Using univariate statistics, we find that opportunity entrepreneurs remain in self-employment longer than...

This paper shows that there are severe measurement errors regarding the occupational affiliations in the German Socio-Economic Panel. These errors are traced back to the survey structure: in years where occupational information is gathered from the entire employed population instead of only from...

This paper explores the difference between intentions and realizations in return migration with the help of a duration model. Using the GSOEP the results lend support to the fact that people use simplifying heuristics when trying to forecast the future; their return intentions indicate bunching...

This paper applies semiparametric regression models using penalized splines to investigate the profile of well-being over the life span. Splines have the advantage that they do not require a priori assumptions about the form of the curve. Using data from the British Household Panel Survey (BHPS)...

Posner (1995) proposes the redistribution of health spending from old women to old men to equalize life expectancy. His argument is based on the assumption that the woman's utility is higher if her husband is alive. Using self-reported satisfaction measures from a long-running German panel...

We use life satisfaction and Body Mass Index (BMI) information from three waves of the SOEP to test for social interactions in BMI between spouses. Social interactions require that the cross-partial effect of partner's weight and own weight in the utility function be positive. Using life...

In dieser Arbeit kommt ein neuer ökonometrischer Ansatz für Paneldaten zum Einsatz, welcher den Umgang mit persistenter, unbeobachtbarer Heterogenität in allgemeinen nichtseparablen und nonparametrischen Konstellationen ermöglicht. Der Ansatz geht zurück auf Hoderlein und White (2009)....

We present a semiparametric method to estimate group-level dispersion, which is particularly effective in the presence of censored data. We apply this procedure to obtain measures of occupation-specific wage dispersion using top-coded administrative wage data from the German IAB Employment...

To explore single mothers' labor market participation we analyze specific circumstances and dynamics in their life courses. We focus on the question which individual and institutional factors determine both professional advancement and professional descent. Due to dynamics in women's life course...

The paper provides new evidence on the outmigration of foreign-born immigrants. We make use of data from the German Socio-Economic Panel and employ penalised spline smoothing in the context of a Poisson-type Generalised Additive Mixed Model (GAMM), which enables us to incorporate bivariate...
