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 no more impatient than white children. However, this pattern hides the fact that black boys have the highest...

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...

One of the reasons why market economies are able to thrive is that they exploit the willingness of entrepreneurs to take risks that laborers might prefer to avoid. Markets work because they remunerate good judgement and punish mistakes. Indeed, modern contract theory is based on the assumption...

We present a series of experiments to understand the nature and extent of discrimination in urban Lima, Peru. The experiments exploit varying degrees of information on performance and personal characteristics as people sort into groups to test for statistical versus taste-based discrimination....

Crime in the mail sector can hamper the development of electronic markets. We use a field experiment to detect crime and measure its differential impacts. We subtly, and realistically, manipulate the content and information available in mail sent to households and detect high levels of shirking...

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...

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...

In the State of Georgia, agricultural irrigation permits in the Flint River Basin had been routinely granted until a moratorium was placed on permit issuance in 1999. This research exploits this policy change within a hedonic pricing framework to estimate the value of irrigation rights in the...

Lottery experiments have been performed in many contexts to test theories of risk aversion and to measure risk preferences. People are typically offered a series of lotteries with increasing expected payoffs and variances. A person with a concave utility function should switch from risky bets to...
