Development of human societies requires cooperation among unrelated individuals and obedience to social norms. Although punishment is widely agreed to be potentially useful in fostering cooperation, many recent results in psychology and economics highlight punishments' failures in this regard....

Temptation and self-control in intertemporal choice environments are receiving increasing attention in the theoretical economics literature. Nevertheless, there remains a scarcity of empirical evidence from controlled environments informing behavior under repeated temptations. This is...

Does transparent leadership promote cooperative groups? We address this issue using a public goods experiment with exogenously selected leaders who are able to send non-binding contribution suggestions to the group. To investigate the effect of transparency in this setting we vary the ease with...

Previous research offers compelling evidence that leaders suffice to effect efficiency-enhancements on cooperation, yet the source of this effect remains unclear. To investigate whether leadership effects can be attributed exclusively to the common information that leaders provide to a group,...

We report data from a laboratory experiment using dictator games to inform individual preferences over punishment outcomes. We find that many people punish after receiving disadvantageous outcomes, and those who do systematically prefer to use punishment to create self-advantageous inequality.

We report data from public goods games showing that privately-implemented punishment reduces cooperation in relation to a baseline treatment without punishment. When that same incentive is implemented publicly, however, cooperation is sustained at significantly higher rates than in either the...
