Inequality in Parental Transfers and Optimal Need-Based Financial Aid Staff Working Paper 2019-7 Youngmin Park This paper studies optimal need-based financial aid when parental transfers—unobserved by policymakers—vary across and within families of similar means. Using data on U.S. college students, I document substantial inequality in parental transfers, especially among wealthier families. I then analyze how this affects aid design aimed at reducing inefficiencies from borrowing constraints and the aid itself.
