We develop a game-theoretical model of honesty and fairness to study cooperation in social dilemma games with communication. It is based on two key intuitions. First, players suffer a utility cost if they break norms of honesty and fairness, and this cost is highest if most others comply with...

Many people judge that it is permissible to harm one person in order to save many in some circumstances but not in others: it matters how the harm comes about. Researchers have used trolley problems to investigate this phenomenon, eliciting moral judgments or behavioral predictions about...

Experiments show that people give money away to other people, even when contributions are anonymous. These findings contradict the common economic assumption that people maximize their own payoffs. Here we take the approach that human altruism is shaped by a set of cognitive models for distinct...

We conduct two simple experiments in which student participants are invited to give some of the money that they have earned to an international development charity for use in one of two African countries. In the between-groups experiment, participants are given the opportunity to donate to one...

We investigate how cross-cutting ethnic and religious identities as well as the strength of individual religiosity and fundamentalism affect individual cooperation. In a repeated prisoner’s dilemma experiment, information about subjects’ religious and ethnic identities was either revealed or...

This paper presents a model of real effort provision in conjunction with rational social preference theory to predict how individuals exert effort to replace an exogenously determined “state of the world” with a preferred social outcome. Binary dictator games and real effort tasks are used...

Standard social choice experiments generally force subjects to make decisions about giving money to another person, but the ability to avoid information outside of the lab could lead to less altruistic or fair behavior than such experiments tend to suggest. I expand on the design of Dana, Weber,...

Do potential entrepreneurs exploit welfare-destroying opportunities as much as they exploit welfare-enhancing opportunities as it is assumed in several normative models? Do we need to prevent potential entrepreneurs from being destructive or are there intrinsic limits to harm others? We...

Many stated preference studies report framing effects in responses to valuation questions. Framing in stated preference studies occurs when respondents use irrelevant information contained in the question to help them value the good. This may occur because respondents are uncertain or do not...

We investigate the relationship between participation in physical activity and self reported happiness in the United States. IV estimates based on data from the Behavioral Risk Factor Surveillance System between 2005 and 2009 and County Business Patterns indicate that individuals living in a...
