Does one hat fit all? the case of corporate leadership structure

Recent corporate scandals have led to renewed campaigns for governance reforms, including calls for the separation of CEO and chairman positions. This paper argues that this trend ignores the possibility that differences in firm characteristics determine the appropriateness of separating or combining the two positions. I propose and test hypotheses on the determinants of leadership structure using a sample of 1,883 firms. I find that organizational complexity, CEO reputation, and managerial ownership increase the probability of CEO duality. I also find that whether CEO duality benefits or hurts the firm is contingent on firm and CEO characteristics. These results suggest that firms do consider the costs and benefits of alternative leadership structures, and that requiring all firms to separate CEO and chairman duties may be counterproductive. © 2007 Springer Science+Business Media, LLC.
