Professor Qualities and Student Achievement
分析大学教师质量的重要性，通过匹配教师的主客观特征，估计职称、薪资和感知有效性对学生成绩和学科兴趣的影响，发现主观评价有效而客观特征无效，教师差异整体影响小但存在重要异常值。
This paper analyzes the importance of teacher quality at the college level. Instructors are matched to objective and subjective characteristics of teacher quality to estimate the impact of rank, salary, and perceived effectiveness on student performance and subject interest. Student and course fixed effects, time of day and week controls, and students' lack of knowledge about first-year instructors help minimize selection biases. Subjective teacher evaluations perform well in measuring instructor influences on students, while objective characteristics such as rank and salary do not. Overall, the importance of college instructor differences is small, but important outliers exist.
