Gender, trust and cooperation in environmental social dilemmas.

This research addresses gender differences in environmental protection efforts. Recent work indicates that, across a variety of domains, women are more generous, charitable, and prosocial than men. Despite above-average levels of these motivators for cooperation, considerable experimental research points to no difference in cooperation between genders.

A normative explanation of antisocial punishment.

While much research shows that people punish free-riders, recent studies find evidence that people also engage in antisocial punishment. That is, they sometimes punish those who contribute generously to collective actions. Such sanctioning is puzzling because generous individuals increase the welfare of all group members.
