			\item Notes: Dependent variable is the quit ratio. Standard errors clustered at the establishment level in parentheses. */ **/ *** denote significance at the 10\%/5\%/1\% level, respectively. Coefficients and standard errors are rounded at the fourth decimal.  Statistics and corresponding p-values from F-test on joint significance of (Treat $\times$ Post) and (Treat $\times$ Post $\times$ Coll. Agr.) in specification (3) and (4) are 5.08 (0.006) and 5.08 (0.006), respectively. Wage sum per capita is measured in 1000 Euros.
