The Impact of Advice on Women's and Men's Selection into Competition

We conduct a laboratory experiment to study how advice affects the gender gap in the entry into a real-effort tournament. Our experiment is motivated by the concerns raised by approaching the gender gap through affirmative action. Advice is given by subjects who have already had some experience with the participation decision. We show that advice improves the entry decision of subjects, in that forgone earnings due to wrong entry decisions go significantly down. This is mainly driven by significantly increased entry of strong performing women, who also become significantly more confident, and reduced entry of weak performing men.
