This paper experimentally explores how the enforcement of cooperative behavior in a social dilemma is facilitated through institutional as well as emotional mechanisms. Recent studies emphasize the importance of negatively valued emotions, such as anger, which motivate individuals to punish free...

Lying to participants offers an experimenter the enticing prospect of making "others' behaviour" a controlled variable, but is eschewed by experimental economists because it may pollute the pool of subjects. This paper proposes and implements a new experimental design, the Conditional...

We compare a partners condition where the same small group of subjects plays a repeated public good game to a strangers condition where subjects play this game in changing group formations. Subjects in the partners condition contribute from the first period on significantly more to the public...

We study fairness and reciprocity in a Hawk-Dove game. This alllows us to test various models in one framework. We observe a large extent of selfish and rational behavior. Our results are inconsistent with leading models in this field.

Tax Liability Side Equivalence (tax LSE) claims that the statutory incidence of a tax is irrelevant for its economic incidence. In gift-exchange labor markets, firms provide a gift to workers by paying high wages, and workers reciprocate by providing high efforts. Tax LSE is theoretically...
