In-Group Cooperation and Gender: Evidence from an Interdisciplinary Study

Wide range of group factors is of particular interest since they are the most significant reason for the differentiation of human economic behavior between two poles—altruism and egoism. This study presented the results of experiments aimed to investigate how group composition (heterogeneous vs. homogeneous in terms of a group members’ gender) affected cooperation and group outcome. Applying the methodology of experimental economics and social psychology, we found that heterogeneous groups were most effective in terms of cooperation.
