We measure sources of racial inequality in stockbroker pay. Pay differences arise from sales differences. We measure the extent to which sales differences are due to performance‐support bias, whereby African American brokers receive weaker firm supports, or to forces outside the firm, including client access, selection, and consumer discrimination. Data on firm policies are matched to sales results. Data on self‐generation of accounts measure access to wealthy clients. Sales generated from accounts with sales histories show racial differences in sales arising from selection or consumer discrimination.
