College Choice and Wages: Estimates Using Data on Female Twins
利用明尼苏达州同卵和异卵双胞胎调查数据，评估大学质量对女性收入的影响，发现私立研究型大学能显著提高毕业生收入，且教育数量和质量分配加剧了人力资本不平等。
The authors assess the impact of college quality on women's earnings and the influence of family and individual endowments on college choice using new data from a survey of identical and nonidentical twins born in Minnesota. The estimates reject models that ignore school choice. The statistically preferred estimates suggest that Ph.D.-granting, private universities with well-paid senior faculty and smaller enrollments produce students who have significantly higher earnings later in life. Both the quantity of schooling and the quality of schooling resources are allocated to higher-endowed individuals, which exacerbates preexisting inequality in human capital and biases conventional estimates of school quality effects.
