Labor market segmentation theory, particularly the dual labor market theory, received substantial attention from economists in the United States in the 1970s. In the 1980s, interest waned due to theoretical and empirical problems within the analysis itself, and the labor market changes emerging from the “search for flexibility” on the part of employers and government policymakers. Segmentation still remains amidst the, perhaps, more “flexible” labor markets of today. The political economy of labor market segmentation is still a useful framework for studying crucial issues facing workers in the United States.
