In this week’s New York Times, Dana Goldstein and Anemona Hartocollis write about the difference in enrollments at the Ivy Plus (eight Ivy League universities plus Duke, Stanford, M.I.T., and the University of Chicago) institutions when students’ family incomes are considered. The source of the data for these reporters is a paper co-authored by economists Raj Chetty, John Friedman, Emmanuel Saez, Nicholas Turner, and Danny Yagan, Income Segregation and Intergenerational Mobility Across Colleges in the United States. The paper follows their 2017 research paper, Mobility Report Cards: The Role of Colleges in Intergenerational Mobility.
