The Effect of High School Courses on Earnings
利用高中及以后转录数据，估计六种高中数学课程对学生毕业近十年后收入的影响，发现高级课程效果更大，且数学课程有助于缩小低收入与中等收入家庭学生的收入差距。
We estimate the effect that six types of high school math courses have on students' earnings nearly a decade after graduation. We use High School and Beyond transcript data to differentiate courses at a more detailed level than in previous research. This enables us to show that more-advanced courses have larger effects than less-advanced ones. We also provide evidence that math courses can help close the earnings gap between students from low-income and middle-income families. Finally, by incorporating other academic subjects, we demonstrate how specific course combinations can explain the earnings premium related to an additional year of school. © 2004 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
