Abstract: The fact that men trade more than women in financial markets has been attributed to men's overconfidence. However, evidence supporting this view is only indirect. We directly test this conjecture experimentally, by measuring confidence using monetary incentives before participants trade in a simulated market. We find that men are more confident than women in our trading task. Men also trade more, and they hold larger and less diversified portfolios than women. However, we do not find that differences in confidence explain any portion of the gender gap in trading activity. We explore alternative candidate channels such as risk aversion, financial literacy or competitiveness but find that these factors are also unlikely to play a role.
