Regulation, unionization, and racial wage discrimination: An analysis of the trucking industry

Abstract

This article tests the hypothesis that increased product market competition of deregulation decreased employer and union wage discrimination in the motor carrier industry. Specifically, in each regulatory period, we estimate the portion of the industry racial wage differential that is due to racial differences: in driver attributes, returns to attributes, and unionization. Our findings suggest that enhanced product market competition directly reduces wage discrimination and may have a smaller indirect effect of further reducing racial wage disparities in industries with racially exclusive unions. These findings support the use of competition to reduce wage discrimination as opposed to government intervention.
