This paper analyses the relationship between locus of control (LOC) and the demand for supplementary health insurance. Drawing on longitudinal data from Germany, we find robust evidence that individuals having an internal LOC are more likely to take up supplementary private health insurance...

We study the impact of short-term exposure to ambient air pollution on the spread and severity of Covid-19 in Germany. We combine data on county-by-day level on confirmed cases and deaths with information on local air quality and weather conditions and exploit short-term variation in the...

In order to get the COVID-19 pandemic under control, most governments around the globe have adopted some sort of containment policies. In the light of the enormous costs of these policies, in many countries highly controversial discussions on the adequacy of the chosen policies evolved. We...
