The Effect of School Rank on Personality Traits
利用高中班级内学生成绩分布差异造成的排名外生变化，发现班级排名显著提升尽责性，但对其他大五人格特质无影响，机制是感知能力和学业动机。
We study the effect of classroom rank on high-school students’ Big Five personality traits. We exploit idiosyncratic differences in the class distribution of earlier academic achievement. Such differences generate quasi-random variation in class rank for students with the same initial achievement. We find a positive and sizeable effect of rank on conscientiousness, but we find no effects on the other four personality traits. A thorough analysis of the mechanism suggests that the primary channels through which class rank improves conscientiousness are perceived ability and academic motivation.
