Ownership Structure and Power: Evidence from US Corporations

We examine the influence of ownership structure on a blockholder’s power in a firm. We first describe the presence and ownership stakes of blockholders in a comprehensive sample of US firms. We develop a measure of the influence of the ownership structure on a blockholder’s power and show that an average blockholder loses 12% of her potential power due to the presence and size of the ownership stakes of other blockholders. Further, the influence of ownership structure varies systematically with a blockholder’s rank and identity, with the second and nonfamily manager blockholders experiencing the largest loss of power.
