The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults ...

Using quantile regression methods, this paper analyses the gender wage gap across the wage distribution and over time (1990-2014), while controlling for changing sample selection into full-time employment. Our findings show that the selection-corrected gender wage gap is much larger than the one observed in the data, which is mainly due to large positive selection of women into full-time employment. ...

The availability of childcare is a crucial factor for mothers’ labour force participation. While most of the literature examines childcare for preschool children, we specifically focus on primary school-aged children, estimating the effect of formal afternoon care on maternal labour supply. To do so, we use a novel matching technique, entropy balancing, and draw on the rich and longitudinal data of ...

Does the geographical concentration of ethnic minorities influence their descriptive representation in closed-list systems? Counterintuitive to the idea that single-member district electoral rules are necessary for minorities’ geographical representation, we argue that, in closed-list systems, parties are incentivised to allocate promising list positions to those minority candidates who are based in ...

Männer, die im Alter von 25 bis 34 Jahren mindestens einmal wöchentlich Sport getrieben haben, können ihre Bruttostundenlöhnen in den folgenden neun Jahren um 6,39 Euro mehr steigern als sportlich Inaktive.

Dass die Lebenslagen von alleinerziehenden Familien deutlich ungünstiger sind als von Paarfamilien, ist in der Literatur vielfach dokumentiert. Allerdings ist wenig darüber bekannt, inwieweit das Fehlen des zweiten Elternteils im Haushalt ursächlich hierfür ist und welche Rolle es spielt, dass es bei Müttern in verschiedenen Lebenslagen unterschiedlich häufig zu Trennungen und zum Eingehen neuer Partnerschaften ...

Daher wurde ihr Zusammenhang mit Löhnen und Erwerbslosigkeit anhand von drei unterschiedlichen Datensätzen analysiert. Beim Nationalen Bildungspanel und der PIAAC-Studie wurden die Deutschkenntnisse mittels standardisierter ...

As a result the knowledge used in production was redefined and reformers pushed for radical reform in vocational and general education. In these decades a corporate agreement across trade unions, associations of employers and state bureaucracy ...

This paper investigates how working from home affects employees’ work effort. Employees who have the possibility to work from home have a high autonomy in scheduling and organizing their work and are therefore assumed to have a higher intrinsic motivation. Thus, we expect working from home to positively influence work effort of employees. We introduce a theoretical model that analyzes whether intrinsic ...
