برآورد رابطه بین نیاز مالی محاسبه شده و کمک واقعی دریافت شده با استفاده از ابزارهای تولد سه ماهه

When calculating financial need, the FAFSA does not consider the parental income of students who turn 24 years old. This paper uses the student's quarter of birth interacted with the treated cohort to instrument for financial need. Using the interaction mitigates many of the concerns regarding quarter of birth instruments. A dollar increase in financial need is associated with 15 cents in federal grants and 47 cents in loans. However, the relationship between financial need and institutional aid is, on average, small and statistically insignificant. The exception is that institutions with large endowments do allocate more aid to more-needy students.
