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...

We experimentally investigate the distribution of children's time preferences along gender and racial lines. Black boys have significantly larger discount rates than any other demographic group. Discount rates among Black girls are comparable to rates among White girls. Although White boys...

We examine optimal incentives for charitable giving with a large-scale field experiment involving 26 charities and over 112,000 unique individuals. The price of giving is varied by offering a fixed match if the donation meets a threshold amount (e.g. "give at least $25 and the charity receives a...

We investigate the consistency and stability of individual risk preferences by manipulating cognitive resources. Participants are randomly assigned to an experiment session at a preferred time of day relative to their diurnal preference (circadian matched) or at a non-preferred time (circadian...

We examine gender differences in bargaining outcomes in a highly competitive and commonly used market: the taxi market in Lima, Peru. Examining the entire path of negotiation we find that men face higher initial prices and rejection rates. These differentials are consistent with both statistical...

This paper presents a series of experiments on discrimination in urban Lima, Peru. The experiments exploit degrees of information on performance as a way to assess how personal characteristics affect how people sort into groups, and the results show that behavior is not correlated with personal...

Friends can influence many aspects of one's life, including giving behavior. Using data on 10,000 donors from a field experiment with an online giving community, we examine the effectiveness and underlying motivations for donors to ask friends via social media to give to a charity. Asking a...

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...
