Study Reveals Noncompete Clauses Harm Worker Earnings Without Protecting Secrets
Cambridge, Wednesday, 7 October 2026.
New academic research demonstrates noncompete agreements suppress worker earnings and mobility without offering superior trade-secret protection compared to standard nondisclosure agreements, regardless of whether the clauses are legally enforceable.
Quantifying the Labor Market Drag
A groundbreaking study published in The Quarterly Journal of Economics on 7 August 2026 provides empirical evidence regarding noncompete agreements [2]. Researchers Evan Starr, Bo Cowgill, and Brandon Freiberg analyzed over 14,000 job offers across two finance firms to determine the impact of these clauses [1][2]. The findings challenge the justification for widespread noncompete enforcement by linking them directly to suppressed wage growth and talent mobility [1].
The Illusion of Legal Protection
The research demonstrates that noncompetes offer no measurable benefit in protecting proprietary business information compared to standard nondisclosure agreements [1]. Crucially, unenforceable noncompetes, such as those in California, restricted mobility as effectively as enforceable ones [1][2]. This suggests the mere presence of the clause changes behavior regardless of legal validity [2].
Global Regulatory Divergence
While the Federal Trade Commission’s proposed nationwide ban on noncompetes was recently halted in court, federal agencies and state-level regulators are increasing scrutiny [1][2]. Internationally, separate employment reforms in Australia would ban non-compete clauses for lower- and middle-income workers with proposed 2027 commencement [4]. Dentons’ Q3 2026 global employment newsletter highlights similar trends in contractor classification and non-compete restrictions across 35+ jurisdictions [3].
