Notes: This table reports the differential effect of CNC enforceability on cumulative number of jobs taken across workers’ employment history in Panel B and on cumulative earnings across workers’ employment history in Panel A by industry (high-tech jobs vs. nontech jobs) of the worker’s first job. The dependent variables are the log of cumulative number of jobs taken at 4th, …, 32nd quarter of the workers’ employment history in Panel B and the log of cumulative earnings at 4th, …, 32nd quarter of the workers’ employment history in Panel A. The high-tech job dummy variable is that of the first job of the worker. CNC score is measured as the 2009 CNC enforceability index scores of the state where the first job of the worker is geographically located. The job-level fixed effects controls for the job characteristics of the first job of the worker. Data are from the LEHD (1991–2008). All standard errors are clustered by state.
