University Admission and the Similarity of Fields of Study: Effects on Earnings and Skill Usage
利用丹麦大学录取系统的断点，发现被心仪专业录取但备选专业差异大的学生，其收入和技能使用有长期显著提升；而备选专业相似的学生则无此效应。
Using discontinuities from the Danish college enrollment system, we find that students who are marginally accepted into their preferred program in a broad field that is different from their next-best choice (e.g., business rather than science) experience significant and long-lasting rewards as a result. In contrast, students whose preferred and next-best programs lie within the same broad field do not. Exploiting data from online job postings, we find that the estimated effects on skill usage similarly vary according to the degree of similarity between preferred and next-best choices.
