Notes: This table reports the differential effect of CNC enforceability on job duration by industry (high-tech jobs vs. nontech jobs). The dependent variables are dummy variables for the job spell surviving at 4th, …, 32nd quarter of the job spell for Columns 1–8, and the log of length of job spells in number of quarters for Column 9. CNC score is measured as the 2009 CNC enforceability index scores. Estimation samples are all jobs that are not right-censored by the quarter for Columns 1–8 and all jobs that started its spell in year 2000 or earlier for Column 9. Data are from the LEHD (1991–2008). All standard errors are clustered by state.
