Increasing Enrollment in Income‐Driven Student Loan Repayment Plans: Evidence from the Navient Field Experiment
通过一家大型贷款服务商Navient的随机现场实验，发现向借款人提供预填好的收入驱动还款计划申请表，能使参与率提高34个百分点，并首次用实验方法评估了该政府项目对拖欠、月还款和消费的影响。
ABSTRACT We report evidence from a randomized field experiment conducted by a major student loan servicer, Navient, in which student loan borrowers received prepopulated applications for income‐driven repayment (IDR) plans. Treatment increased IDR enrollment by 34 percentage points relative to the control group. Using the random treatment assignment as an instrument for IDR enrollment, we furthermore provide local average treatment effect (LATE) estimates of the effects of IDR enrollment on new delinquencies, monthly student loan payments, and consumer spending. Our study is the first field‐experimental evaluation of a U.S. government program designed to address the soaring debt burdens of U.S. households.
