Achievement Rank Affects Performance and Major Choices in College
利用学生随机分配到教学班的数据，研究发现更高的班级排名能提升学生成绩，并增加他们选择相关后续课程和专业的概率，且排名变化的影响具有不对称性。
Abstract In this paper we study how a student's ordinal rank in a peer group affects performance and specialisation choices in university. By exploiting data with repeated random assignment of students to teaching sections, we find that a higher rank increases performance and the probability of choosing related follow-up courses and majors. We document two types of dynamic effect. First, earlier ranks are less important than later ranks. Second, responses to rank changes are asymmetric: improvements in rank raise performance, while decreases in rank have no effect. Rank effects partially operate through students’ expectations about future grades.
