A finite‐sample hierarchical analysis of wage variation across public high schools: evidence from the NLSY and high school and beyond
利用NLSY和HSB数据，用有限样本估计方法分析公立高中是否影响毕业生未来收入，发现学校间存在差异，但学校质量指标解释力有限，教师教育和家庭收入有微弱作用。
Abstract Using data from both the National Longitudinal Survey of Youth (NLSY) and High School and Beyond (HSB), we investigate if public high schools differ in the “production” of earnings and if rates of return to future education vary with public high school attended. Given evidence of such variation, we seek to explain why schools differ by proposing that standard measures of school “quality” as well as proxies for community characteristics can explain the observed parameter variation across high schools. Since analysis of widely‐used data sets such as the NLSY and HSB necessarily involves observing only a few students per high school, we employ an exact finite sample estimation approach. We find evidence that schools differ and that most proxies for high school quality play modest roles in explaining the variation in outcomes across public high schools. We do find evidence that the education of the teachers in the high school as well as the average family income associated with students in the school play a small part in explaining variation at the school‐level.
