Subgroup analyses based on CEO-CFO tenure difference. To further rule out the possibility that our results are driven by the alternative explanation that CEOs select similar and/or submissive CFOs, we test our hypotheses using firm-year observations that CEO tenure starts after CFO tenure starts (around one third of all firm-year observations in the sample). When CEO tenure starts after CFO tenure starts, it is unlikely that the CFO is selected by the CEO. If our results hold using this subsample, this would indicate that CEO-CFO LSM is less likely to be driven by this alternative selection explanation.
