This paper investigates the impact of work group diversity on performance. Analyzing a uniquely large sample of management teams from the U.S. mutual fund industry we find that the influence of diversity on performance depends on the dimension of diversity that is analyzed. While diversity in tenure and educational diversity of fund management team members is positively related to performance, gender diversity is negatively related to performance. Age diversity has no strong impact. Our results have important implications for the optimal composition of work groups and for investment strategies of fund investors.
