Cook, Jens Ludwig, and Justin McCrary (forthcoming, University of Chicago Press), which was made possible through generous support from the MacArthur Foundation and the Public Welfare Foundation. We thank Christopher Edley, Debby Leff, Jim Poterba, and Michael Stegman for making the volume conference and the book itself possible. We thank Jonathan Caulkins, John Donohue and two anonymous referees for valuable comments on an earlier draft, and to Clive Belfield and Henry Levin for their assistance with calculating the social benefits of dropout prevention.
