We experimentally investigate how firms and consumers react to a sudden cost increase in a competitive retail market. We compare two conditions which exclusively differ with respect to how difficult it is to organize and enforce boycotts. We find that cost increases translate into sudden price...

Punishing free riders might promote cooperation, but it can also lead to feuds. We use a public good game with punishment opportunities to investigate whether the threat of feuds is e¢ ciency enhancing. Treatments di¤er with respect to whether a punish- ment can trigger a feud. In the main...

In order to address the impact of regulation on ethical concerns of consumers, we study the effect of a minimum wage. In our experimental market, consumers have monopsony power, firms engage in Bertrand competition, and workers are passive recipients of a wage payment. Two treatments are...

Several authors have made attempts to improve the explanatory power of models of inequality aversion, in particular the one by Fehr and Schmidt (1999), by adding concerns for total surplus or efficiency. In this note, I point out that these attempts are misguided because they are equivalent to a...

We assess the predictive power of a model of other-regarding preferences--inequality aversion--using a within-subject design. We run four different experiments (ultimatum game, dictator game, sequential-move prisoners' dilemma and public-good game) with the same sample of subjects. We elicit two...

We study behavior in a moonlighting game with unequal initial endowments. In this game, predictions for second-mover behavior based on inequality aversion are in contrast to reciprocity. We find that inequality aversion explains only few observations. The comparison to a treatment with equal...
