Are two heads better than one? An experiment with novice share traders

Abstract

We compare the performance of individual and two-person teams in an electronic share-trading task. Trader profits are negatively related to the amount of trader market activity and positively related to trader confidence. While we find no evidence of a difference in trading profit between individual and team traders, profit volatility is more sensitive to trading activity for teams. Team trading profit is positively related to attitude and negatively related to perceptions of the difficulty of the task, with overall team trading activity negatively related to views of team members'abilities.
