Cultural diversity and team performance in the Italian Serie A

Cultural diversity features prominently in management studies. A diverse range of skills and perspectives can produce innovation and a greater variety of solutions to day to day problems. At the same time, however, the same heterogeneous approaches and experiences can result in communication and coordination problems, lack of trust and intra/intergroup conflict. We analyse a newly constructed dataset on team composition and performance for 29 teams, 1,238 players and 1,899 matches in the Italian Serie A with information on the players’ place of origin, talent, position, demographics, manager experience and other factors. We compute indices of fractionalization and polarization and find that both measures of diversity have a strong and persistent negative effect on game scores and player objective performance ratings. This research provides new important insights into the drawbacks of cultural heterogeneity in the workplace and calls for more indepth analyses of the nexus diversity-performances on team performance.
