High School Majors and Future Earnings
利用瑞典高中录取的断点回归设计，发现工程、自然科学和商科专业比社会科学和人文学科带来更高收入，且专业回报取决于次优选择。
We study how high school majors affect adult earnings using a regression discontinuity design. In Sweden students are admitted to majors in tenth grade based on their preference rankings and ninth grade GPA. We find engineering, natural science, and business majors yield higher earnings than social science and humanities, with major-specific returns also varying based on next-best alternatives. There is either a zero or a negative return to completing an academic program for students with a second-best nonacademic major. Most of the differences in adult earnings can be attributed to differences in occupation, and to a lesser extent, college major.
