Racial Gaps in Student Loan Repayment and Default:
A Life Cycle Approach
(joint with Kartik Athreya, Christopher Herrington, Urvi Neelakantan)
Student loan default rates are significantly higher for Black borrowers than for White borrowers
and this gap persists when controlling for education attainment. Black college graduates are four times
more likely than White graduates to default on student loans while non-graduates are only about twice
as likely to default. This is despite the fact that the distribution of loan amounts is similar across Black
and White borrowers and that monthly student loan payments are often smaller for Black individuals
since they are more likely to enroll in income driven repayment plans. To what extent can observable
differences in financial circumstances account for the racial gap in student loan default rates? Are the
factors driving the gap similar for college graduates and non-graduates? Does the financial burden
associated with student debt affect choices later in life in the same way across the two groups? To
address these questions, we construct a life cycle consumption-savings model that captures observed
heterogeneity in initial wealth, human capital risk, student loan debt and repayment choices, earnings
processes, including racial wage discrimination, and unobserved heterogeneity at the time of labor
market entry. We use our model to quantify the degree to which each of these channels contributes
to the observed gap in Black-White student loan default rates over the life cycle.
