All variables are defined in the same way as shown in the Appendix. Panel A shows the results in the marginal effect of probit model that controls for time fixed effect. Panel B exhibits the results estimated by two-stage least squares equations. The first stage equation is estimated by the OLS regression that controls for the time-fixed and industry-fixed effects. The second stage equation is estimated by probit model that controls for the time-fixed and firm-fixed effects. The t-statistics are reported in parentheses. ***, **, and * denote significance at the 1%, 5%, and 10% levels, respectively.
