Wearing the Same Jersey? The Impact of Players' Cultural Diversity and Shared Team Tenure on National Soccer Team Performance.

In the present paper, we empirically analyze a dataset from national soccer teams between 2004 and 2019 to investigate the impact of team members' cultural diversity on final team outcomes. Further, we examine the role of shared team tenure as a proxy of tacit knowledge and within team communications in relation to the cultural diversity-team performance relationship. After addressing a potential endogeneity issue, results from multiple instrumental variable estimation methods implied a higher level of cultural diversity enhanced on-field performance. Meanwhile, increased level of shared team tenure further strengthened the effect associated with cultural diversity on team performance.
