September 2014Why Do People Give? Testing Pure and Impure Altruism
with Mark Ottoni-Wilhelm, Huan Xie: w20497
The extant experimental design to investigate warm glow and altruism elicits a single measure of crowd-out. Not recognizing that impure altruism predicts crowd-out is a function of giving-by-others, this design's power to reject pure altruism varies with the level of giving-by-others, and it cannot identify the strength of warm glow and altruism preferences. These limitations are addressed with a new design that elicits crowd-out at a low and at a high level of giving-by-others. Consistent with impure altruism we find decreasing crowd-out as giving-by-others increases. However warm glow is weak in our experiment and altruism largely explains why people give.
May 2012Gender Differences in Bargaining Outcomes: A Field Experiment on Discrimination
with Marco Castillo, Ragan Petrie, Máximo Torero: w18093
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 and taste-based discrimination. To identify the source of the inferior treatment of men we conduct an experiment where passengers send a signal on valuation before negotiating. The signal eliminates gender differences and the response is shown only to be consistent with statistical discrimination. Our study secures identification within the market of interest and demonstrates that there are environments where sophisticated statistical inference is the sole source of differential gender outcomes.

April 2008How Costly is Diversity? Affirmative Action in Light of Gender Differences in Competitiveness
with Muriel Niederle, Carmit Segal: w13923
Recent research documents that while men are eager to compete, women often shy away from competitive environments. A consequence is that few women enter and win competitions. Using experimental methods we examine how affirmative action affects competitive entry. We find that when women are guaranteed equal representation among winners, more women and fewer men enter competitions, and the response exceeds that predicted by changes in the probability of winning. An explanation for this response is that under affirmative action the probability of winning depends not only on one's rank relative to other group members, but also on one's rank within gender. Both beliefs on rank and attitudes towards competition change when moving to a more gender-specific competition. The changes in competitive ...

July 2005Do Women Shy Away From Competition? Do Men Compete Too Much?
with Muriel Niederle: w11474
Competitive high ranking positions are largely occupied by men, and women remain scarce in engineering and sciences. Explanations for these occupational differences focus on discrimination and preferences for work hours and field of study. We examine if absent these factors gender differences in occupations may still occur. Specifically we explore whether women and men, on a leveled playing field, differ in their selection into competitive environments. Men and women in a laboratory experiment perform a real task under a non-competitive piece rate and a competitive tournament scheme. Although there are no gender differences in performance under either compensation, there is a substantial gender difference when participants subsequently choose the scheme they want to apply to their next per...
