This paper argues that the structure of corporate ownership varies systematically in ways that are consistent with value maximization. Among the variables that are empirically significant in explaining the variation in ownership structure for 511 U.S. corporations are firm size, instability of profit rate, whether or not the firm is a regulated utility or financial institution, and whether or not the firm is in the mass media or sports industry. Doubt is cast on the Berle-Means thesis, as no significant relationship is found between ownership concentration and accounting profit rates for this set of firms.
