Abstract: We study the efficiency of non‐compete agreements (NCAs) in an equilibrium model of labour turnover. The model is consistent with empirical studies showing that NCAs reduce turnover and average wages for low‐wage workers. The model also predicts that, by reducing turnover, NCAs raise recruitment and employment. We show that optimal NCA policy: (i) is characterized by a Hosios‐like condition that balances the benefits of higher employment against the costs of inefficient congestion and poaching; (ii) depends critically on the minimum wage; and (iii) alone cannot always achieve the constrained‐efficient allocation—a result that also holds for optimal minimum wage policy—yet with both policies, efficiency is always attainable. To guide policymakers, we derive a sufficient statistic in the form of an easily computed employment threshold above which NCAs are necessarily inefficiently restrictive, and show that employment levels in current low‐wage US labour markets typically exceed this threshold. Finally, we calibrate the model and show that Oregon's 2008 NCA ban for low‐wage workers increased welfare modestly (by roughly 0.1%), and that if policymakers had also raised the minimum wage to its optimal level conditional on the enacted NCA ban (a 30% increase), then welfare would have increased more substantially—by over 1%.
