Notes: OLS, firm random effects (RE), and firm fixed effects (FE) regressions of ln (Tobin’s q) on aspects of ESG and control variables for 2003-2016. All variables are winsorized at 1 and 99 percent. t-values (in parentheses) use firm clusters. Significant results (at 5 percent level or better) are in italic. *,**,***Significant at 10, 5 and 1 percent level, respectively (suppressed for constant term)
