International trade patterns at the product level are surprisingly dynamic. The majority of trade relationships exist for just a few, often only one to three, years. In this paper, I examine empirically the duration in German import trade at the 8-digit product level from 1995 to 2005. I find...

This research examines re-entry into the labour force for mothers after maternity leave. The empirical analysis focuses on the first twenty-two years of post-reunification Germany, using proportional hazards models. Results show that the re-entry into part-time employment is primarily affected...

We analyze the return-migration of German immigrants using the latest data of the German Socio- Economic Panel from 1984 to 2006. We conduct a Cox proportional hazard model with years of residence in Germany as waiting time. The analysis reveals that return migration is heavily influenced by...

It is becoming more and more important to be highly skilled in order to integrate successfully into the labor market. Highly skilled workers receive higher wages and face a lower risk of becoming unemployed, compared to poorly qualified workers. We analyze the determinants of successful high...

Parkinson's law states that work expands to fill the time available for its completion and that the number of administrators in an office is bound to increase over time. An unique laboratory to test Parkinson's ideas are vehicle registration offices in Germany. Using their data we found...

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...
