Is There a Varying Unexplained Gender Wage Gap in Germany?

The nonlinear link between height and wages in Germany, 1985-2004

Based on data of the German Socio-Economic Panel, this article investigates the relationship between height and wages by gender. Unlike previous investigations, which have been limited to an examination of linear effects, this one finds that height influences on wages are curvilinear, and more so for men than for women. More specifically, it finds that women who are shorter than average and men who ...

Are Tall People Less Risk Averse than Others?

This paper examines the question of whether risk aversion of prime-age workers is negatively correlated with human height to a statistically significant degree. A variety of estimation methods, tests and specifications yield robust results that permit one to answer this question in the affirmative. Hausman-Taylor panel estimates, however, reveal that height effects disappear if personality traits and ...

Health and Body Mass Index: No Simple Relationship

Many studies have shown that obesity is a serious health problem for our society. Empirical analyses often neglect a number of methodological issues and relevant influences on health. This paper investigates empirically whether neglecting these items leads to systematically different estimates. Based on data from the German Socio-Economic Panel, this study derives the following results. (1) Many combinations ...

Health and weight – gender-specific linkages under heterogeneity, interdependence and resilience factors

Many studies have shown that obesity is a serious health problem for our society. Empirical analyses often neglect a number of methodological issues and relevant influences on health. This paper investigates empirically whether neglecting these items leads to systematically different estimates. Based on data from the German Socio-Economic Panel, this study derives the following results. (1) Many combinations ...

The Role of Body Weight for Health, Earnings, and Life Satisfaction

Based on the German Socio-Economic Panel, the influence of the body mass index on health, earnings and satisfaction is analysed by gender. Basic results are: health worsens, income declines and satisfaction is poorer with higher body mass index. If control variables are added, estimates are split by gender and different effects of over- and underweight people are determined, the health estimates show ...

Heritability of time preference: Evidence from German twin data

Intergenerational correlations of time preference are well documented. However, there is still limited empirical evidence about the role of genetics in this transmission process. In our paper, we use data on roughly 3,000 twins from the German TwinLife project to estimate the heritability of time preference. We rely on an experimentally validated survey measure of temporal discounting, namely, self-assessed ...

The Standard Portfolio Choice Problem in Germany

We study an investment experiment with a representative sample of German households. Respondents invest in a safe asset and a risky asset whose return is tied to the German stock market. Experimental investments correlate with beliefs about stock market returns and exhibit desirable external validity at least in one respect: they predict real-life stock market participation. But many households are ...
