Altruistic punishment is often thought to be a major enforcement mechanism of social norms. I present experimental results from a modified version of the dictator game with third-party punishment, in which third parties can remain ignorant about the choice of the dictator. I find that a...

This paper studies whether people can avoid punishment by remaining willfully ignorant about possible negative consequences of their actions for others. We employ a laboratory experiment, using modified dictator games in which a dictator can remain willfully ignorant about the payoff...

We investigate if decision makers exploit moral wiggle room in green market settings. We therefore implement a laboratory experiment in which subjects purchase products associated with externalities. In six between-subjects treatments, we alter the availability of information on the...

We test different classic migration theories by using incentivized laboratory experiments to investigate how potential migrants decide between working in different destinations. We test theories of income maximization, skill-selection, and multi-destination choice as we vary migration costs,...

Inspired by Fröhlich and Oppenheimer (1990), an experimental survey in the lab was designed to find out if preferences for three different redistribution schemes differ under a veil of ignorance. The three schemes are a stylized version of the status quo German welfare state (A), a control...

Experiments involving multiple public goods with contribution thresholds capture many features of charitable giving environments in which donors try to coordinate their contributions across various potential recipients. We present results from a laboratory experiment that introduces endowment...

We study response behavior in surveys and show how the explanatory power of selfreports can be improved. First, we develop a choice model of survey response behavior under the assumption that the respondent has imperfect self-knowledge about her individual characteristics. In panel data, the...

In addition to discrimination, market power, and human capital, gender differences in risk preferences might also contribute to observed gender wage gaps. We conduct laboratory experiments in which subjects choose between a risky (in terms of exposure to unemployment) and a secure job after...

We provide an example for an errors in variables problem which might be often neglected but which is quite common in lab experimental practice: In one task, attitude towards risk is measured, in another task participants behave in a way that can possibly be explained by their risk attitude. How...
