Economists consider personality traits to be stable, particularly throughout adulthood. However, evidence from psychological studies suggests that the stability assumption may not always be valid, as personality traits can respond to certain life events. Our paper analyzes whether and to what...

Western labor markets face major challenges caused by demographic changes. They increasingly experience a shortage of skilled workers and face the problem of an increasing disparity between a reduced group of active workers contributing to the pension scheme and a rising share of an older...

This paper estimates sibling correlations in cognitive and non-cognitive skills to evaluate the importance of family background for skill formation. Based on a large representative German dataset including IQ test scores and measures of non-cognitive skills, a restricted maximum likelihood model...

Whereas the number of paid overtime hours declined over the last two decades in Germany, a different trend can be observed for unpaid overtime. We analyze future consequences of unpaid work with respect to a worker?s career advancement, such as higher future wages and probabilities of promotion...

Empirical studies on the earnings effects of tobacco use have found significant wage penalties attached to smoking. We produce evidence that suggests that these estimates are significantly upward biased. The bias arises from a general failure in the literature to control for the past smoking...

We contribute to the literature on the relationship between cognitive abilities and labour market outcomes providing first evidence for Germany. In particular, cross-sectional data from the German Socio-Economic Panel (SOEP) are used, which include two measures of cognitive ability, one test of...
