Summary

This study examines the impact of same-race coworkers on employee retention using Brazilian administrative employer-employee data. The research exploits unexpected worker deaths of different racial groups as exogenous shocks to analyze peer effects.

Key findings include:

• A decrease in non-white coworker share reduces non-white employees' retention by approximately 1.1 percentage points
• White employees' retention is unaffected by racial composition changes
• Non-white employees are more sensitive to peer racial composition
• Effects vary by occupation type and peer group characteristics
• Higher-skilled workers and those in less team-oriented roles show stronger effects
• Larger personal relationship ties with deceased workers reduces sensitivity to racial composition

The results suggest non-white employees have stronger preferences for same-race work environments, leading to higher voluntary turnover when exposure to same-race peers decreases. Workplace policies should consider this dynamic to promote diversity beyond recruitment.
