Using an easy math task for children older than eight years and a running task for the younger ones we find that boys are much more likely to enter a tournament than girls across the whole age spectrum considered here. This gender gap is observed already with three-year olds, indicating that gender differences in competitiveness emerge very early in life. The gap is robust to controlling for gender differences in risk attitudes and overconfidence. %K teenagers %K competition %K experiment %K gender gap %K children
