Abstract
We study the relationship between the enforceability of covenants not to compete (CNCs) and employee mobility and wages. We exploit a 2015 CNC ban for technology workers in Hawaii and find that this ban increased mobility by 11% and new-hire wages by 4%. We supplement the Hawaii evaluation with a cross-state analysis using matched employer-employee data. We find that eight years after starting a job in an average-enforceability state, technology workers have about 8% fewer jobs and 4.6% lower cumulative earnings relative to equivalent workers starting in a non-enforcing state. These results are consistent with CNC enforceability increasing monopsony power.
