Freshman Year Financial Aid Nudges: An Experiment to Increase FAFSA Renewal and College Persistence
通过随机对照试验，研究个性化短信提醒对大一学生续签联邦助学金（FAFSA）和持续就读的影响，发现对社区大学学生效果显著，但对四年制大学学生无改善。
Abstract In this paper we investigate, through a randomized controlled trial design, the impact of a personalized text messaging intervention designed to encourage college freshmen to refile their Free Application for Federal Student Aid (FAFSA) and maintain their financial aid for sophomore year. The intervention produced large and positive effects among freshmen at community colleges where text recipients were almost 14 percentage points more likely to remain continuously enrolled through the Spring of sophomore year. By contrast, the intervention did not improve sophomore year persistence among freshmen at four-year institutions among whom the rate of persistence was already high.
