Florida International University (FIU) is a public university in Florida that uses a GPA threshold as part of its admissions process. Zimmerman (2014) uses fuzzy regression discontinuity design that examines students just above and just below FIU’s academic cutoff for admissions. This allows the author to calculate the impact of admissions on years of school attended and future earnings. Hendren and Sprung-Keyser (2020) utilize this work to estimate the MVPF of admission to FIU.
Pays for Itself
The total long-run cost of admission to Florida International University is determined both by federal expenditures on schooling and by the long-run impact of FIU admission on earnings, which impacts government revenue via high taxes and reduced transfers.
Zimmerman (2014) provides estimates of the total level of educational expenditures induced by an additional FIU enrollment. The author finds that admission to FIU increases total expenditures in the Florida State University System but decreases total expenditures in the Florida Community College System. (Some students who enroll in FIU would have enrolled in community college if FIU hadn’t admitted them.) Costs paid by the government are calculated by taking the increase in total expenditures and netting out the private contributions made by enrolled students. Zimmerman (2014) draws upon figures from the Delta Cost Project for estimates of yearly schooling expenditures and student contributions toward schooling expenses. All of these estimates are then scaled by the change in the relative probability of enrollment at FIU versus other schools as a result of the admission of a student to FIU. Hendren and Sprung-Keyser (2020) discount these expenditures over four years and report the total public cost per admitted student is $2,617.
Hendren and Sprung-Keyser (2020) calculate the changes in taxes paid and transfers received due to admission at FIU. The willingness to pay section below walks through in detail how they use estimates from Zimmerman (2014) to calculate the lifetime earnings gains from admission. They then apply a tax and transfer rate to determine the impact of those earnings on government revenue. The tax and transfer rate is based on estimates from the Congressional Budget Office. They find that the $142,757 lifetime earnings impact from FIU enrollment results in a fiscal externality of $27,062. When combined with the educational expenditures, that results in $24,44 net windfall for the government.
Zimmerman (2014) observes earnings changes over the course of 14 years, distinguishing between earnings declines in years 1-7 and earnings gains in years 8-14. Summing those earnings changes and discounting by 3% back to the time of initial expenditure produces an earnings rise of $25,427. Hendren and Sprung-Keyser (2020) use the earnings gains observed in years 8-14 and project those gains over the lifecycle. (In particular, they ACS data to estimate life-cycle earnings trajectories and then map the control group in Zimmerman (2014) onto those trajectories. They assume that the control group earnings remain constant as a fraction of average ACS earnings throughout the life cycle. They also assume that the percentage earnings increase for the treatment group also remains constant throughout the life cycle.) Using this projection, Hendren and Sprung-Keyser (2020) find a lifetime earnings impact of $142,757. They calculate post-tax and post-transfer earnings by incorporating a tax rate on earnings in each year. Hendren and Sprung-Keyser (2020) also subtract out individual contributions to tuition in future years, which reduces willingness to pay by $2,851. This results in a total willingness to pay of $112,844.
Combining these estimates, Hendren and Sprung-Keyser (2020) obtain an MVPF of \infty, with a confidence interval of (\infty,\infty). They also consider a specification where admission to FIU is valued at the cost of the transfer rather than based on the change in long-term earnings. This conservative method for calculating willingness to pay ignores any effect from increases in earnings but also results in a 95% confidence interval of (\infty,\infty) .
