Gender and Generosity: Does Degree of Anonymity or Group Gender Composition Matter?

Employing a two-by-two factorial design that manipulates whether dictator groups are single or mixed-sex and whether procedures are single or double-blind, we examine gender effects in a standard dictator game. No gender effect was found in any of the experimental treatments. Moreover, neither single- versus mixed-sex groups nor level of anonymity had any impact on either male or female behavior.
