The Impact of College Teaching on Students’ Academic and Labor Market Outcomes
利用博科尼大学行政数据和税收记录，通过学生随机分配教师，估计大学教学对学生学业成绩和收入的影响，发现教师对两者的效果仅微弱正相关，对能力较弱的学生甚至呈负相关。
This paper estimates the impact of college teaching on students' academic achievement and labor market outcomes using administrative data from Bocconi University matched with tax records. The estimation exploits the random allocation of students to teachers in a fixed sequence of compulsory courses. We find that teacher effects on students' academic and labor market outcomes are only mildly positively correlated and that the professors who are best at improving the academic achievement of their students are not always also the ones who boost their earnings the most. For the least able students, the correlation between the academic and labor market effectiveness of teachers turns out to be negative.
