Do Returns to Schooling Differ by Race and Ethnicity?
利用美国人口普查和全国纵向调查数据，发现不同种族和民族群体的教育回报率差异不大，但标准误较大；非洲裔和西班牙裔的回报率并不低于非少数族裔，提高低技能群体教育可能有助于减少不平等。
Using data from the U.S. Decennial Census and the National Longitudinal Surveys, we find little evidence of differences in the return to schooling across racial and ethnic groups, even with attempts to control for ability and measurement error biases. While our point estimates are relatively similar across racial and ethnic groups, our conclusion is driven in part by relatively large standard errors. ; That said, we find no evidence that returns to schooling are lower for African Americans or Hispanics than for non-minorities. As a result, policies that increase education among the low-skilled have a good possibility of increasing economic well-being and reducing inequality. More generally, our analysis suggests further research is needed to better understand the nature of measurement error and ability bias across subgroups in order to fully understand potential heterogeneity in the return to schooling across the population.
