Why Do Minority Men Earn Less? A Study of Wage Differentials among the Highly Educated
用非参数匹配方法分析大学毕业生数据，发现少数族裔男性的工资差距部分源于教育测量误差，而黑人的差距中仅约四分之一能被教育等因素解释，但南方以外且父母有大学教育的黑人样本中差距可完全解释。
We estimate wage gaps using nonparametric matching methods and detailed measures of field of study for university graduates. We find a modest portion of the wage gap is the consequence of measurement error in the Census education measure. For Hispanic and Asian men, the remaining gap is attributable to premarket factors-primarily differences in formal education and English language proficiency. For black men, only about one-quarter of the wage gap is explained by these same factors. For a subsample of black men born outside the South to parents with some college education, these factors do account for the entire wage gap.
