Abstract:
We analyze how the gender composition of teams affects team interactions. In an online experiment, we randomly assign individuals to gender-homogenous or gender-mixed teams. Teams meet in an audio chat room and jointly work on a gender-neutral team task. By design, effects on team performance can only work through communication. We find that all-male teams communicate more than all-female teams and outperform teams of both alternative gender compositions. In mixed teams, males strongly dominate the team conversation quantitatively. Past exposure to gender-mixed teamwork makes females more reluctant to engage in mixed teams, while for males the opposite is true.
