Interfirm Segregation and the Black/White Wage Gap
利用两个新建的企业层面数据库，研究企业间种族隔离现象，发现黑人和白人工人的企业间分布接近随机分配，但黑人工人更集中在管理者、所有者或顾客也是黑人的雇主中，且黑/白工资差距主要发生在企业内部。
This article studies interfirm racial segregation in two newly developed firm-level databases. The authors find that the interfirm distribution of black and white workers is close to what would be implied by random assignment. They also find that black workers are clustered in employers where managers, owners, and customers are also black. These findings may be reconciled by the facts that there are not enough black employers to generate much segregation and that other forces may systematically integrate black and white workers. Finally, the authors find that the black/white wage gap is primarily a within-firm phenomenon. Copyright 1998 by University of Chicago Press.
