We test the importance of social norms for market interactions associated with negative real-world externalities in a large-scale experiment with a heterogeneous population sample from Germany. The majority of experimental participants refuses to trade, thus behaving in a moral way. Our data...

The paper aims at testing Florida's concept of the Creative Class using panel data for 323 West German regions for the time period 1975 - 2004. Applying a dynamic system approach based on GMM, we find that the local concentration of the Creative Class has predictive power for the economic...

This paper investigates the long-term effects of the Paraguayan War (1864-1870) on intimate partner violence. The identification of these causal effects relies on a novel historical dataset from which I exploit the distance from municipalities to military camps during the war. Over 130 years...

Does the politico-economic system affect preferences for immigration? In this study, I show that individuals exposed to life under state socialism have formed and persistently hold different attitudes toward immigration. By exploiting the division and reunification of Germany, I estimate the...

International climate negotiations have so far failed to produce ambitious climate cooperation. We combine laboratory experiments with simulations to investigate the performance of two negotiation design features to address this failure: The Paris Agreement's ratchet-up mechanism, which requires...

Microcredit, a financial tool providing uncollateralized loans to low-income individuals, has seen a shift from joint-liability (JL) to individual liabil- ity (IL) lending models. This article tests a theory explaining this shift, focusing on borrowers matching into groups exposed to similar...

Review systems including quantitative measures as well as text-based expression of experiences are omnipresent in today's digital platform economy. This paper studies the existence of reputation inflation, i.e. unjustified increases in ratings, with a special focus of heterogeneity between...

A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners' dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they...

I investigate if, how, and why the effect of a contribution rule in a public goods game depends on how it is implemented: endogenously chosen or externally imposed. The rule prescribes full contributions to the public good backed by a nondeterrent sanction for those who do not comply. My...
