How does financial aid affect postsecondary enrollment, college choice, and student composition? We present new evidence based on a large-scale program available to high-achieving, low-income students for attending high-quality colleges in Colombia. RD estimates show financial aid eligibility raised immediate enrollment by 56.5 to 86.5 percent, depending on the complier population. This rise, driven by matriculation at private, high-quality colleges, closed the SES enrollment gap among high achievers. Moreover, a DID approach suggests enrollment of aid-ineligible students also improved because college supply expanded in response to heightened demand. With ability stratification largely replacing SES stratification, diversity increased 46 percent at private, high-quality colleges.

针对低收入学生的基于大学成绩的经济援助的上游和下游影响：哥伦比亚的 Ser Pilo Paga

经济援助如何影响中学后入学、大学选择和学生构成？我们提供了新的证据，该计划基于一项可供高成绩、低收入学生进入哥伦比亚高质量大学的大型计划。RD 估计显示，经济援助资格将立即入学率提高了 56.5% 至 86.5%，具体取决于编制者人口。在私立、高质量大学预科的推动下，这种上升缩小了高成就者之间的 SES 入学差距。此外，DID 方法表明不符合援助资格的学生的入学率也有所提高，因为大学供应因需求增加而扩大。随着能力分层在很大程度上取代了 SES 分层，私立、高质量大学的多样性增加了 46%。
