Introducing a peer punishment mechanism sustains contributions … stigmatization effect for the special agent as he receives substantially more peer punishment while contributions by other agents do … not change. Finally full transparency of all agents actions creates full accountability as it allows targeted punishment …

This paper studies experimentally how the endogeneity of sanctioning institutions affects the severity of punishment in … when subjects can vote on the institutional setting. We find that punishment is significantly higher when the sanctioning … institution is exogenous, which can be explained by a difference in the effectiveness of punishment. Subjects respond to …

We use an experiment to test the hypothesis that groups consisting of like-minded cooperators are able to cooperate … irrespective of punishment and therefore have a lower demand for a costly punishment institution than groups of like-minded free … riders, who are unable to cooperate without punishment. We also predict that the difference in the demand for punishment is …

Considerable experimental evidence shows that although costly peer-punishment enhances cooperation in repeated public …-good games, heavy punishment in early rounds leads to average period payoffs below the non-cooperative equilibrium benchmark.
