    Résumé : "Brave Boys and Play-it-Safe Girls : Gender Differences in Willingness to Guess in a Large Scale Natural Experiment".

    • We study gender differences in a sample with over 9,000 multiple-choice math tests, where in half of the questions both wrong answers and omitted questions score 0, and in the other half wrong answers score 0 but omitted questions score +1. Using a within-participant regression analysis, we find that female participants leave more omitted questions than males under both types of scoring rules, but furthermore, the gender difference gets larger when there is a reward for omitted questions. This gender difference, which is stronger among high ability and older participants, has negative consequences for females in the final score and ranking. In a subsequent survey, female participants show lower levels of confidence and higher risk aversion, which could potentially explain this differential behavior. When both are considered, risk aversion seems to be the main factor in explaining the gender differential in the willingness to guess. A scoring rule that is gender neutral begs for non-differential scoring between wrong answers and omitted questions.
