We investigate whether peer punishment is an efficient mechanism for enforcing cooperation in an experiment with a long time horizon. Previous evidence suggests that the costs of peer punishment can be outweighed by the benefits of higher cooperation, if (i ) there is a sufficiently long time...

The growing concentration of resources among the rich has re-ignited a discussion about whether the rich are more selfish than others. While many recent studies show the rich behaving less pro-socially, endogeneity and selection problems prevent safe inferences about differences in social...

Extensive evidence from laboratory experiments indicates that many individuals are willing to use costly punishment to enforce social norms, even in one-shot interactions. However, there appears to be little evidence in the literature of such behavior in the field. We study the propensity to...
