College Summer School
通过随机分配暑期奖学金给社区大学学生，发现该政策能显著加速学位进程，一年内毕业率提高32%，转入四年制大学的比例提高58%。
<h3>Abstract</h3> We experimentally examine whether a policy targeting college summer school enrollment can accelerate degree progress and completion. We randomly assign summer scholarships to community college students and find a large impact on degree acceleration, increasing graduation within one year of the intervention by 32% and transfers to four-year colleges by 58%. We elicit preferences for the scholarships and find substantial treatment effects on enrollment, graduation, and transfer among students with a preference <i>against</i> summer school. These results suggest that many more students could benefit from summer school than the minority who currently enroll.
