Student beauty and grades under in-person and remote teaching
利用瑞典工科学生数据，研究发现面对面教学时，相貌出众的学生在非量化课程中成绩更高；疫情转线上后，漂亮女生成绩下降，但男生仍享有美貌溢价，暗示歧视是女生美貌溢价的关键因素。
This paper examines the role of student facial attractiveness on academic outcomes under various forms of instruction, using data from engineering students in Sweden. When education is in-person, attractive students receive higher grades in non-quantitative subjects, in which teachers tend to interact more with students compared to quantitative courses. This finding holds both for males and females. When instruction moved online during the COVID-19 pandemic, the grades of attractive female students deteriorated in non-quantitative subjects. However, the beauty premium persisted for males, suggesting that discrimination is a salient factor in explaining the grade beauty premium for females only.
