Legacy Admissions and Social Mobility

Legacy admissions, particularly at elite colleges and universities, were thrust into the spotlight this summer when the U.S. Supreme Court effectively ended affirmative action in admissions. The ruling raised many questions, and fortunately, Harvard Kennedy School professor David Deming and Harvard Economics Professor Raj Chetty were there with some important answers—having just wrapped up a 6-year study of the impact of legacy admissions at so-called “Ivy-plus” schools. Students spend years preparing to face judgment by colleges and universities as a worthy potential applicant. They strive for report cards filled with A’s in advanced placement courses. They volunteer for service projects and participate in extracurricular activities. They cram furiously high-stakes standardized tests. They do all that only to find a big question many top colleges have is effectively: “Who’s your daddy? And who's your mother? Did they go to school here?” Using data from more than 400 colleges and universities and about three and a half million undergraduate students per year, the two economists found that legacy and other elite school admissions practices significantly favor students from wealthy families and serve a gate-keeping function to positions of power and prestige in society.

David Deming’s Policy Recommendations:

• Build a robust system of collecting and measuring the distribution of income for admitted students at colleges across the country.
• Make standardized data in student income distribution transparent and widely available to facilitate better educational policy decisionmaking.

Raj Chetty’s Policy Recommendations:

• Rework legacy admissions and other practices at elite colleges to reduce bias in favor of students from high-income families
• Improve access for low- and middle-income students to a broader array of private, public, and community colleges as a means to promote economic mobility

Raj Chetty is the William A. Ackman Professor of Public Economics at Harvard University. He is also the director of Opportunity Insights, which uses “big data” to understand how we can give children from disadvantaged backgrounds better chances of succeeding. Chetty's research combines empirical evidence and economic theory to help design more effective government policies. His work on topics ranging from tax policy and unemployment insurance to education and affordable housing has been widely cited in academia, media outlets, and Congressional testimony. Chetty received his Ph.D. from Harvard University in 2003 and is one of the youngest tenured professors in Harvard's history. Before joining the faculty at Harvard, he was a professor at UC-Berkeley and Stanford University. Chetty has received numerous awards for his research, including a MacArthur "Genius" Fellowship and the John Bates Clark medal, given to the economist under 40 whose work is judged to have made the most significant contribution to the field.

David Deming is the Isabelle and Scott Black Professor of Political Economy and the academic dean of the Harvard Kennedy School. He is also the faculty dean of Kirkland House at Harvard College and a research associate at NBER. His research focuses on higher education, economic inequality, skills, technology, and the future of the labor market. He is a principal investigator (along with Raj Chetty and John Friedman) at the CLIMB Initiative, an organization that seeks to study and improve the role of higher education in social mobility. He is also a faculty lead of the Project on Workforce, a cross-Harvard initiative that focuses on building better pathways to economic mobility through the school-to-work transition. He recently co-founded (with Ben Weidmann) the Skills Lab, which creates performance-based measures of “soft” skills such as teamwork and decision-making. In 2022 he won the Sherwin Rosen Prize for outstanding contributions to Labor Economics. In 2018 he was awarded the David N. Kershaw Prize for distinguished contributions to the field of public policy and management under the age of 40. He served as a Coeditor of the AEJ: Applied from 2018 to 2021. He also writes occasional columns for the New York Times Economic View, which you can find linked on his personal website.
