Engelmann and Strobel (AER 2004) claim that a combination of efficiency seeking and minmax preferences dominates inequity aversion in simple dictator games. This result relies on a strong subject pool effect. The participants of their experiments were undergraduate students of economics and...

We run a public good experiment in the field and in the lab with (partly) the same subjects. The field experiment is a true natural field experiment as subjects do not know that they are exposed to an experimental variation. We can show that subjects' behavior in the classic lab public good...

We implement the Rawlsian veil of ignorance in the laboratory. Our experimental design allows separating the effects of risk and social preferences behind the veil of ignorance. Subjects prefer more equal distributions behind than in front of the veil of ignorance, but only a minority acts...

We present evidence from a laboratory experiment showing that individuals who believe they were treated unfairly in an interaction with another person are more likely to cheat in a subsequent unrelated game. Specifically, subjects first participated in a dictator game. They then flipped a coin...

We analyze distributional preferences in games in which a decider chooses the provision of a good that benefits a receiver and creates costs for a group of payers. The average decider takes into account the welfare of all parties and has concerns for efficiency. However, she attaches similar...

We study experimentally whether anti-corruption policies with a focus on bribery might be insufficient to uncover more subtle ways of gaining an unfair advantage. In particular, we investigate whether an implicit agreement to exchange favors between a decision-maker and a lobbying party serves...

Crime has to be punished, but does punishment reduce crime? We conduct a neutrally framed laboratory experiment to test the deterrence hypothesis, namely that crime is weakly decreasing in deterrent incentives, i.e. severity and probability of punishment. In our experiment, subjects can steal...

We address a basic diffculty with incorporating fairness into standard utilitarian choice theories. Standard utilitarian theories evaluate lotteries according to the (weighted) utility over ?nal outcomes and assume in particular that a lottery is never preferred over getting the most preferred...

Physicians' treatment decisions determine the level of health care spending to a large extent. The analysis of physician agency describes how doctors trade off their own and their patients' benefits, with a third party (such as the collective of insured individuals or the taxpayers) bearing the...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004This paper explores predictability of behavior in coordination games with multiple equilibria. In a laboratory experiment we measure subjects' certainty equivalents for three coordination games and one lottery. Attitudes...
