Non-traditional students in higher education drop out more often than traditional students. To understand this difference more clearly, this paper examines differences between the two groups with regard to sociodemographic characteristics, study contexts and life circumstances, as well as individual assessments of prospects of academic success and the costs and returns of studying. A decomposition analysis shows that student age and study context are two factors that have a particularly strong significance for the higher tendency of non-traditional students to drop out. This paper suggests ways in which theoretical models for explaining educational decisions could be adapted with regard to the special group of non-traditional students.

Collecting life history data is highly demanding and therefore prone to error since respondentsmust retrieve and provide extensive complex information. Research has shown that responseburden is an important factor influencing data quality. We examine whether increases indifferent measures of response burden in a (mixed-device) online survey lead to adverseeffects on the data quality and whether these effects vary by the type of device used (mobileversus non-mobile).

This paper studies the evolution of three higher education wage differentials from 1996 to 2019 in Germany. We distinguish between degrees from academic universities, degrees from universities of applied sciences, and the master craftsman\craftswoman certificate. The educational reference category is a standard degree within the German vocational education and training system. Based on samples of male and female workers from the Socio-Economic Panel Study (SOEP), regression methods show that all three educational wage differentials in 2019 exceeded the ones in 1996. However, workers graduating from universities experienced an inverse u-shape pattern with a maximum of about 0.5 log points around 2012....

This piece of research, entitled „Labor market segmentation and overqualification. An analysis of employment adequacy among PhDs“, examines the employment situation of doctoral graduates in Germany using segmentation theory approaches and to takes a critical look at the measurement of employment adequacy. Two questions are adressed: 1. how do segmentation theory indicators, especially the placement within different labor market segments, influence the probability that doctoral graduates are adequately employed? And 2. how do structural conditions of the labor market affect different levels of adequacy of doctoral graduates? The study refers to the data based on the PhD-panel 2014 from DZHW. The empirical analysis showed that while ...
