Gender differences in interpersonal and intrapersonal competitive behavior

Gender differences in competitive behavior continue to be documented by economists and other social scientists; however, the bulk of the research addresses competition with others and excludes other economically relevant contests. In this paper, we ask: how does gender affect how individuals react to competing against themselves? In a laboratory experiment in which some subjects compete against others and some compete against themselves, we find women select into intrapersonal competition at significantly higher rates than interpersonal competition and comparatively more than men. In addition, we find that while perseverance or "grit" does not explain the gender difference in behavior, risk attitudes have some explanatory power.
