We explore the importance of appearance in the endogenous formation of groups using a series of experiments. Participants get to choose who they want in their group, and we manipulate the amount of payoff-relevant information on behavior, thereby making it costly to discriminate based on...

"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 judgment and punish mistakes. Indeed, modern contract theory is based on the assumption...

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 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....

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...
