"This book is well worth reading for its models of elegant research, parsimonious theorizing, and provocative results." — American Journal of Sociology"This is a superbly written book that uses state-of-the-art techniques to build our knowledge of product market structure and labor market discrimination. The topic is central to labor economics and to public policies surrounding both industrial organization/product market regulation and to racial and gender antidiscrimination efforts." — Robert W. Drago, coauthor of Unlevel Playing Fields: Understanding Wage Inequality and Discrimination
