Few events give the opportunity to observe the full range of human behavior as wars do. In the case of civil wars in ethnically-mixed societies, the distribution of violence across various segments of the population can provide evidence on the extent and nature of discrimination. As in the case...

The ultimatum game has been the primary tool for studying bargaining behavior in recent years. However, not enough information is gathered in the ultimatum game to get a clear picture of respondersâ?? utility functions. We analyze a convex ultimatum game in which respondersâ?? can...

There is growing evidence of systematic heterogeneity in behavior by observable characteristics, such as what one would see in a face. We ask, is there informational value in knowing these characteristics in a strategic interaction? Subjects are given the opportunity to purchase a photograph of...

We present experimental evidence consistent with statistical discrimination in a public good and group formation game. We find that behavior is correlated with race and gender, and people use race and gender to predict behavior when no other information is available. When information on behavior...

We investigate the distribution of risk preferences and the frequency of expected utility violations along the gradient of market development. To do this, we collect experimental and survey data from a random sample of the population at four sites in Peru that differ in their level of...

The existence of a beauty premium in the labor market and the male-female wage gap suggests that appearance can matter in the real world. We explore beauty and gender in a public goods experiment and find similar effects. We find a beauty premium, even though beautiful people contribute, on...

We investigate the consistency and stability of individual risk preferences by slightly manipulating the cognitive resources of subjects through sleepiness. Participants are recruited and randomly assigned to an experiment session at a preferred time of day relative to their diurnal preference...

Relying on a commonly used fixed-offer bargaining script we examine gender differences in bargaining outcomes in a highly competitive and frequently used market: the taxi market in Lima, Peru. Our bargaining script secures that only the seller can change prices and terminate negotiations, thus...

We experimentally investigate the distribution of children's time preferences along gender and racial lines. We find that boys are more impatient than girls and black children are more impatient than white children. Black boys have the highest discount rates of all groups. Most importantly, we...
