This paper studies the determinants of academic success using a unique administrative data set of a German university. We show that high school grades are strongly associated with both graduation probabilities and final grades, whereas variables measuring social origin or income have only a...

In this paper, we investigate in a controlled laboratory experiment physician behavior in the case of payment heterogeneity. In the experiment, each physician provides medical care to patients whose treatments are paid for either under fee-for-service (FFS) or capitation (CAP). We observe that...

We compare voluntary contributions to the financing of a public good in a symmetric setting to those in asymmetric settings, in which four players have different, randomly allocated endowments. We observe that a weak asymmetry in the endowment distribution leads to the same contribution level as...

For most of human history there existed a well-educated and innovative elite whereas mass education, market R&D, and high growth are phenomena of the modern period. In order to explain these phenomena we propose an innovation-driven growth model for the very long run in which the...

Certificate trading schemes have been discussed as a cost-efficient means of reducing land use in Germany by capping and reallocating permissions to conduct building projects. However, in contrast to the established cap & trade systems for emissions, reputation-seeking politicians would be in...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed "fair-share" rule of equal contributions relative to oneś endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution...

In this paper, we study the rational for an incumbent to launch a second brand when facing potential entry in a market with quality differentiated products and a fringe producer. Depending on market size, costs for a second brand and a potential entrant’s setup cost the incumbent might use a...

This paper studies the effect of a minimum quality standard, a compulsory labeling scheme, and the combination of both instruments in a vertical differentiation model when not all quality dimensions of products can be observed byconsumers. Both a minimum quality standard on the non-observable...

This paper measures the impact of sectoral composition, international trade and technological progress on the rising wage gap in Germany. I find a positive effect of the increasing importance of services on the rising wage gap in Germany that is comparable to the effects of international trade...

Recent empirical research has shown that income per capita in the aftermath of natural disasters is not necessarily lower than before the event. Income remains in many cases not significantly affected or, perhaps even more surprisingly, it responds positively to natural disasters. Here, we...
