This contribution examines whether the share price of the Borussia Dortmund GmbH & Co. KgaA (BVB) behaves according to the (capital) market efficiency hypothesis of Fama (1970). The weak form of capital market inefficiency, according to which past share prices cannot be used for predictions in...

Becoming unemployed has negative effects on life satisfaction; a transition from unemployment to employment, however, has stronger positive effects in absolute terms. The asymmetry of the non-pecuniary effect indicates a potential “omitted variable bias” in previous empirical happiness studies

This paper tests on differences between age-related reductions in the performance of men and women. The assumption that men age faster is obvious, because men′s life expectancy is generally lower. In addition to other studies on age-related reduction in human performance, this paper examines...

Becoming unemployed has negative effects on life satisfaction; a transition from unemployment to employment, however, has only small positive effects. This asymmetry indicates a potential 'omitted variable bias' in previous empirical happiness studies, with the consequence of underestimated...

This paper is the first test of differences between age-related reductions in the performance of men and women. The assumption that men age faster is obvious, because men's life expectancy is generally lower. In addition to other studies on age-related reduction in human performance, this paper...

Typically, laboratory experiments suffer from homogeneous subject pools and self-selectionbiases. The usefulness of survey data is limited by measurement error and by thequestionability of their behavioral relevance. Here we present a method integrating interactiveexperiments and representative...

German federal law has increased the potential duration of maternity leave five times since 1985. A theretical model is presented that demonstrates that the return to work hazard rate declines as potential duration cannot decline unless the mother's employment conditions or career expectations...

An unexpected increase in life expectancy has implications for private pensions (annuities). These can be offset by reducing pension payments, cross-subsidization of the pension payments, risk-taking of insurance companies or combining these policies. An empirical study of the German market of...

The positive effects of early childhood programs on children's school success have been demonstrated in the literature. However, most studies were completed in the U.S.A., where early childhood programs vary widely, based on differing auspice, regulation, cost, and other factors. In European...
