Notes: This table reports the differential effector CNC enforceability on cumulative wage and on wage growth from initial wage, across job tenure, by industry (high-tech jobs vs. nontech jobs). The dependent variables are the log of cumulative wage at 4th, 8th, …, 32nd quarter of the job spell for Panel A, and the difference between the log of monthly wages at 4th, 8th,…, 32nd quarter of the job spell and the log of initial wage for Panel B. CNC score is measured as the 2009 CNC enforceability index scores. Data are from the LEHD (1991–2008). All standard errors are clustered by state.
