The Oxford Series on Human Capital and Economic Opportunity will present state-of-the-art research from a variety of perspectives on the problems of opportunity, human flourishing, and public policy. Volumes in the series will be grouped in accordance with these themes and will be based on the work of HCEO members. In some cases, the volumes will contain research first presented at HCEO conferences, and in others will contain specially commissioned research. The series is published by the Oxford University Press.
