This table reports Chair–CEO age dissimilarity (alternative measures) and IE. Regression (1) to (4) report the results from the OLS regression of the association between GAP20/15/10/5 and IE. Columns (5) to (8) report the results from the Logit regression of the association between GAP20/15/10/5 and IED. t-Statistics in parentheses. *p < 0.10, **p < 0.05, ***p < 0.01. Robust t-statistics (in parentheses) are based on standard errors clustered by firm and year. All variables are defined in Appendix
