Against the backdrop of an ongoing debate in most countries about the geographic (mal-)distribution of physician practices, we develop a theoretical and empirical framework to analyze how physician supply at regional level depends on demographic (population size, age structure, fertility and...

The contribution of this paper is to analyse the role of network interdependencies in a dynamic panel data model for German internal migration flows since re-unification. So far, a capacious account of spatial patterns in German migration data is still missing in the empirical literature. In the...

This paper tests the empirical validity of the neoclassical migration model in predicting German internal migration flows. We estimate static and dynamic migration functions for 97 Spatial Planning Regions between 1996 and 2006 using key labor market signals including income and unemployment...

In Germany, employees are generally obliged to participate in the public health insurance system, where coverage is universal, co-payments and deductibles are moderate, and premia are based on income. However, they may buy private insurance instead if their income exceeds the compulsory...

This paper studies how stress affects the mortality risk. Allowing for time-varying treatment effects, I find no impact of stress on the short-run mortality risk but a substantially increase in the long-run and in particular for men. This is likely caused by changes toward adverse health...

This paper studies how stress affects the mortality risk. Using a flexible approach and allowing for timevarying treatment effects, I find no impact of stress on the short-run mortality risk but a substantially increase in the long-run. The effects are especially pronounced for men. I provide...

The economic costs of chronic health conditions and severe illnesses like diabetes, coronary heart disease or cancer are immense. Several clinical trials give information about the impor-tance of individual behaviour for the prevalence of these illnesses. Changes in health relevant behaviour may...

The question of whether two drugs - namely alcohol and tobacco - are used as complements or substitutes is of crucial interest if side-effects of anti-smoking policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and...
