About the BE-Lab


The Blair Economics Lab (BE-Lab) is an Economics research group based at Clemson University in the John E. Walker Department of Economics. Our research in applied micro-theory focuses on labor market discrimination, residential segregation, and supply-side questions in higher education. In addition to researchers at Clemson University, we work collaboratively with faculty and students from the Wharton School, Duke University, the University of Chicago and Cornell University.

Working Paper

 "Occupational Licensing Reduces Gender and Racial Wage Gaps: 

Evidence from the Survey of Income & Program Participation" (joint w/ Bobby Chung, Clemson)(Co-


Abstract: As a condition for legal employment, US state governments require occupational licenses of 25% of their workforce. We show that occupational licensing reduces the wage gap between black men and white men (by 43%), and the wage gap between women and white men (by 36%-40%). Black men benefit from licenses that signal non-felony status, whereas white women benefit from licenses with a human capital requirement, e.g., continuous education. Certification, a less distortionary alternative to licensing,  generates an equivalent wage premium to occupational licensing for white men, but lower wage premiums than licensing for women and black men.

Why Don't Elite Colleges Expand Supply? (joint w/ Kent Smetters, Wharton)


Abstract: While college enrollment has more-than doubled since 1970, elite colleges have only slightly increased supply, instead reducing admit rates. We show that straightforward reasons cannot explain this behavior. We propose a model where colleges compete on prestige, measured as relative selectivity or admit rates. Higher demand decreases [increases] the admit rate if the weight on prestige is above [below] a critical value, consistent with experience in elite [non-elite] colleges. The calibrated model closely replicates the data while counter-factual simulations, with prestige turned off, fails. The "prestige externality'' is Pareto inefficient, with schools and students worse off, producing large welfare losses.
