The effect of minority status on managerial survival in Major League Baseball is analyzed using survival time analysis and data envelopment analysis. Efficiency scores based on team performance and player salary data from 1985 to 2006 are computed and included as covariates in a survival time analysis. It is shown that when controlling for performance and personal characteristics minorities are on average 9.6 percentage points more likely to return the following season. Additionally, it is shown that winning percentage has no impact on managerial survival when efficiency is controlled for.
