We analyze firms' competition to steer an advisor's recommendations through potentially non-linear incentives. Even when firms are symmetric, so that the overall size of compensation would not distort advice when incentives were linear, advice is biased when firms are allowed to make...

Anthropometric indicators, in particular the height for a particular age, are found to be lowest in South Asia compared to other geopolitical regions. However, despite the close relationship between undernutrition and mortality rates, the highest mortality rates are concentrated in sub-Saharan...

Clustered covariances or clustered standard errors are very widely used to account for correlated or clustered data, especially in economics, political sciences, or other social sciences. They are employed to adjust the inference following estimation of a standard least-squares regression or...

Bayesian methods have become increasingly popular in the past two decades. With the constant rise of computational power even very complex models can be estimated on virtually any modern computer. Moreover, interest has shifted from conditional mean models to probabilistic distributional models...

This paper explores the historical origins of the cultural norm regarding illegitimacy (formerly known as bastardy). We test the hypothesis that traditional agricultural production structures influenced the historical illegitimacy ratio, and have had a lasting effect until today. Based on data...

Despite improvements in global child health within the last three decades, under-5 mortality remains significantly high in Sub-Saharan and Asia. Both regions did not achieve the MDG target of reducing under-5 mortality by two thirds by 2015. The underlying causes of under-5 mortality differ...

This paper investigates - in a large heterogeneous sample - the relationship between social preferences on the one hand, and socioeconomic factors and political preferences on the other hand. Socioeconomic factors correlate with social preferences, and social preferences robustly shape political...

Much is known about heterogeneity in social preferences and about heterogeneity in lying aversion - but little is known about the relation between the two at the individual level. Are the altruists simply up- right persons who do not only care about the well-being of others but also about...

In our experimental setting, participants face the decision to invest into two assets which are subject to correlated information. While fundamental states and signals about fundamental states are correlated, success and default of the investment projects is determined separately. Nevertheless,...

Tournament incentives prevail in labor markets, in particular with respect to promotions. Yet, it is often unclear to competitors how many winners there will be or how many applicants compete in the tournament. While it is hard to measure how this uncertainty affects work performance and...
