All variables are defined in the same way as shown in the Appendix. Panel A exhibits the results for firms in the old economy while panel B shows the results for new-economy firms. The results are estimated based on the OLS regression model with standard errors that are robust and control for time and firm clustering. The t-statistics are reported in parentheses. ***, **, and * denote significance at the 1%, 5%, and 10% levels, respectively.
