The Importance of Cost of Living and Education in Estimates of the Conditional Wage Gap Between Black and White Women
研究发现，在控制劳动市场选择、生活成本和基于AFQT分数的教育年限后，黑人女性的工资溢价消失，说明这些因素对解释工资差距至关重要。
Abstract While evidence about discrimination in U.S. labor markets typically implies preferential treatment for whites, recent studies document a substantial wage premium for black women (for example, Fryer 2011). Although differential selection of black and white women into the labor market has been a suggested explanation, we demonstrate that accounting for selection does not eliminate the estimated premium. We then incorporate two additional omitted variables recently documented in the literature: (1) local cost of living and (2) years of education attained, conditional on AFQT score. After controlling for these variables, we find no evidence of a wage premium for black women.
