Labor Earnings, Discrimination, and the Racial Composition of Jobs
研究劳动力市场中黑人密度对工资率和种族工资差距的影响，发现黑人和白人的工资在黑人密度高的行业-职业-地区组中显著较低，但种族工资差距不随种族密度系统变化。
This paper examines the effect of the racial composition of labor markets on wage rates and the racial wage gap.The wage rates of white as well as black workers are significantly lower in indus try-occupation-regional groups with high densities of black work ers, while the racial wage gap does not vary systematically with respect to racial density.Interpretation of racial gap estimates can be sensitive to inclusion of a racial density variable, particu larly in sparse specifications.An explanation for the wage density relationship cannot be established, but results are most consistent with a quality sorting explanation and, to a lesser ex tent, the crowding hypothesis.
