Like many medical studies, the Berlin Aging Study II (BASE-II) is based on a non-random convenience sample of self-recruited participants. To study processes of selectivity in BASE-II, we used an identical questionnaire to compare BASE-II with a large, representative reference study, the German...

Like many medical studies, the Berlin Aging Study II (BASE·II) is based on a non·random "convenience sample" of self·recruited participants. To study processes of selectivity in BASE·II, we used an identical questionnaire to compare BASE·II with a large, representative reference study, the...

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)...

The paper investigates maternity leave behavior in West Germany for females being employed between 1995 and 2006 using data from the German Socio Economic Panel. The observational study focuses on the investigation of individual and family-related covariate effects on the duration of maternity...

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)....

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...
