Abstract: We address the question of whether using samples drawn from the ExecuComp database affects the results of empirical studies. We find significant differences between ExecuComp and non-ExecuComp firms with regard to the structure of CEO equity and cash compensation. Also, we document that specific inferences from prior work are markedly different for ExecuComp and non-ExecuComp firms. Finally, we find that ExecuComp and non-ExecuComp firms differ systematically with regard to equity ownership and other governance characteristics. In particular, CEOs of ExecuComp firms tend to have lower levels of equity ownership creating a greater separation of ownership and control while ExecuComp firms have a higher proportion and concentration of institutional ownership and are more likely to have an independent nominating committee. Overall, our results suggest that using the ExecuComp database can have a significant effect on the results of empirical corporate governance studies.
