Employee demographic diversity and firm performance

This article examines the relationship between employee demographic diversity and firm performance measured by future stock returns for a large sample of US public companies. We use novel demographic data extracted from employees' online profiles and resumes and focus on three key aspects of employee demographic diversity: age, gender, and ethnicity. We find no evidence supportive of an outperformance associated with greater employee-diverse companies, neither using portfolio-sorting approaches nor cross-sectional and panel regressions. We also find no significant associations between employee demographic diversity and ROE, gross profit, and labor productivity.
