The coexistence of social health insurance and private health insurance in Germany is subject to intense public debate. As only few have the opportunity to choose between the two systems, they are often regarded as privileged by the health insurance system. Applying a hazard model in discrete...

Six randomized control trials were published simultaneously in one issue of the 'American Economic Journal: Applied Economics' in 2015. The studies show no or minimal impact from providing microloans to clients and have led many researchers and policy makers to conclude that microfinance has...

Using a newly available and multifaceted dataset provided by the German Federal Statistical Office, this paper is the first to investigate both technical and cost efficiency of more than 1500 German general hospitals conducting a stochastic frontier analysis. The empirical results for the years...

This paper investigates cost and profit efficiency of German hospitals. More specifically, it deals with the question how hospital efficiency varies with ownership, patient structure,and other exogenous factors, which are neither inputs nor outputs of the production process. We conduct a...

The paper analyses how context and time dependent factors determine the impulse of R&D subsidies on firm behavior with respect to private R&D expenditures. Based on data from the German R&D survey, we combine propensity-score matching with a difference-in-difference-estimator in order to measure...

We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. 'Dictator games' with varying transfer rates used in Andreoni and...

We report the results of a combination of a dictator experiment with either a 'social planner' or a 'veil of ignorance' experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer (BHH,...
