Do Less Informative College Admission Exams Reduce Earnings Inequality? Evidence from Colombia
研究了2000年哥伦比亚大学入学考试改革，发现降低考试信息量虽缩小了分数差距，但导致学生更易辍学，反而降低了高低收入学生的收入。
This paper asks whether reducing the informativeness of college admission exams reduces inequality in postcollege earnings. I examine a 2000 reform of the Colombian college admission exam that sought to reduce bias in scores. The reform reduced test score gaps between high- and low-income students by nearly 50% in some subjects, but it also decreased the exam’s predictive power for abilities that matter in college. I find that the reform caused students to attend colleges where they were more likely to drop out, which reduced earnings for both high- and low-income students.
