Although sample selection bias is a frequent problem of applied research, there has been no generalization of sample selection models with binary dependent variables of interest to data with temporal error correlations. We suggest a generalized estimating equation approach to panel data selection models, considering binary responses in both equations. We demonstrate the utility of this model by a simulation ...

Individuals with a migration background represent a steadily increasing percentage of Germany's population. Although the majority of individuals with migration background lack German citizenship and are therefore unable to vote, the number of naturalized immigrants continues to rise. Accordingly, political parties have been showing greater interest in this group of potential voters. Data from ...

Panel conditioning has posed one of the main challenges to panel studies since their inception in the social sciences. Aside from the risk of reactivity to previous interviews, there is reason to expect that cumulative survey experience increases the reliability of data emanating from panel studies relative to cross-sectional surveys. This positive aspect of recurrent interviewing for data quality ...

In Germany, formal child care coverage rates have increased markedly over the past few decades. The expansion in coverage is particularly pronounced for under 3 year-olds. The present paper is concerned with how mothers’ mental and physical health is affected by whether they place their child in formal day care or not. Furthermore, the effects of formal child care usage on mother-child interaction ...

This paper will contribute to a growing body of research on the concept of public service motivation and its effects. It addresses two important though still largely unexplored questions: How stable or dynamic are prosocial attitudes, and do differences among employees or the individual changes in their attitudes over time matter, in order to explain the performance of prosocial behavior? To learn ...

A gap in research on prosocial motivation is that very little is known about its change across time, let alone, how such changes affect employee behavior. Using multiple waves of panel data, covering a period of sixteen years, this article finds that prosocial motivation is mostly stable, and there are no broader socialization effects in the private and public sector. However, when prosocial motivation ...

We explore the effects of flexible work practices (FWPs) on the work attitudes (job satisfaction and turnover intention) and non-work attitudes (leisure satisfaction and perceived health) of employees based on representative large-scale German panel data. Because unobserved individual characteristics can easily act as confounders, we estimate both pooled OLS models and individual fixed-effects models. ...

Social inequalities in health are a characteristic of almost all European Welfare States. It has been estimated, that this is associated with annual costs that amount to approximately 9% of total member state GDP. We investigated the influence of inequalities in German health care utilization on direct medical costs. We used longitudinal data from a representative panel study (German Socio-Economic ...
