Peter Q. Blair is a member of the faculty at Harvard University’s Graduate School of Education, where he codirects the Project on Workforce. An NBER research associate affiliated with the Economics of Education Program, he is the principal investigator of the Blair Economics Lab, a multi-university collaboration that focuses on supply-side issues in higher education, the effects of occupational licensing on labor market discrimination, and the link between residential segregation and educational outcomes. Four graduates of his lab are now in tenure-track roles in economics departments.

In addition to his scholarly work, Blair served as a volunteer economist with the Council of Economic Advisers during the Biden-Harris presidential transition. He is an active member of his local church, where he mentors graduate students.

Blair received his PhD in applied economics from the Wharton School at the University of Pennsylvania, his master’s in theoretical physics from Harvard, and his bachelor’s degree in physics and mathematics from Duke University. He is the youngest of seven sons and got his start understanding markets by selling fruit and vegetables with his brothers in the Nassau Straw Market in the Bahamas.
