The Economics of Noncompete Clauses

For over 600 years, debates over noncompete clauses have centered on whether they function as efficient contracting tools or anticompetitive restraints on workers. This article reassesses that debate in light of recent policy attention and new empirical and theoretical research. Proponents argue that noncompetes are necessary to protect investments in training and trade secrets, increasing productivity and wages. However, recent studies indicate that the widespread use of noncompetes—frequently extending beyond roles involving sensitive information—and their enforceability lower mobility, wages, innovation, and entrepreneurship. Moreover, in many cases, less restrictive contractual terms appear to safeguard firm interests. Evidence of spillovers to other workers and across state boundaries, as well as behavioral effects even when noncompetes are unenforceable, raises questions about whether existing state-level enforcement regimes adequately address their observed impacts.
