This paper tests the hypothesis that a high and persistent exposure to infectious diseases increases the likelihood of civil conflicts. Diseases that are difficult to prevent and treat may reduce the opportunity costs of violent activities, both directly and indirectly. The analysis exploits new...

Over many decades, academics, policymakers and governments have been concerned with both the presence of inequalities and the impacts these can have on people when concentrated spatially in urban areas. This concern is especially related to the influence of spatial inequalities on individual...

This research argues that deep-rooted factors, determined tens of thousands of years ago, had a significant effect on the course of economic development from the dawn of human civilization to the contemporary era. It advances and empirically establishes the hypothesis that in the course of the...

There is a well-known debate about the roles of geography versus institutions in explaining the long-term development of countries. These debates have usually been based on cross-country regressions where questions about parameter heterogeneity, unobserved heterogeneity, and endogeneity cannot...

We measure the impact of individuals' looks on their life satisfaction or happiness. Using five data sets from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow putting a lower bound on the true effects of beauty on happiness. Personal beauty...

This paper studies differences in inequality perceptions, distributional norms, and redistributive preferences between East and West Germany. As expected, there are substantial differences with respect to all three of these measures. Surprisingly, however, differences in distributional norms are...

In this paper the hypothesis that partnerships between immigrants and natives are less specialized - in the sense that spouses provide similar working hours per weekday - than those between immigrants is tested. The empirical analysis relies on panel data using a two-limit random effects tobit...

This paper systematically investigates whether different kinds of personality characteristics influence entrepreneurial development. On the basis of a large, representative household panel survey, we examine the extent to which the Big Five traits and further personality characteristics, which...

Based on new, exceptionally informative and large German linked employer-employee administrative data, we investigate the question whether the omission of important control variables in matching estimation leads to biased impact estimates of typical active labour market programs for the...

We provide an explanation for the common finding that the effect of retirement on life satisfaction is negligible. For this we use subjective well-being measures for life and domains of life satisfaction that are available in the German Socio-Economic Panel (GSOEP) and show that the effect of...
