The Knappschaft underlies Bismarck's sickness and accident insurance legislation (1883 and 1884), which in turn forms the basis of the German social-insurance system today and, indirectly, many social-insurance systems around the world. The Knappschaften were formed in the medieval period to...

In recent years, the international community has expanded efforts in programme evaluation to improve the accountability of development projects. This paper presents approaches to implementing state-of-the-art evaluations in rural electrification projects, taking into account specific challenges...

This paper provides empirical evidence on the relationship between cross-border acquisitions and innovation activities at the firm level. In contrast to previous studies that analyze the effects on innovation in target firms, this paper investigates the effects on the investing firms. For the...

We contribute to the literature on the determinants of socioeconomic health disparities by studying how the health behavior of adolescents may arise from the degree of communication between parent and child. Parent-child communication may function as a mediator between family background 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 this paper we estimate the effects of college education on cognitive abilities and health exploiting exogenous variation in college availability and student loan regulations. By means of semiparametric local instrumental variables techniques we estimate marginal treatment effects in an...

We study effects of retirement on cognitive abilities (up to ten years after retirement) using data from 21 countries in Continental Europe, England, and the US, and exploiting early-retirement thresholds for identification. For this purpose, combines event-study estimations with the marginal...
