In recent years, both legal scholars and economists have sought to explain these schemes as a rough form of investor protection, shielding small shareholders from exploitation by controlling shareholders in an era when investor protection law was weak.

We argue, in contrast, that restricted voting rules generally served not to protect shareholders as investors, but to protect them as consumers. The firms adopting such rules were frequently local monopolies that provided vital infrastructural services such as transportation, banking, and insurance. The local merchants, farmers, and landholders who used these services were the firms’ principal shareholders. They commonly purchased shares not in the expectation of profit, but to finance collective goods. Restricted shareholder voting assured that control of the firms’ services would not fall into the hands of monopolists or competitors. In effect, the corporations had much the character of consumer cooperatives. This perspective also sheds light on the unusual importance given to the doctrine of ultra vires in the nineteenth century.

While current legal and economic scholarship has focused incessantly on the separation between ownership and control, the prior separation between ownership and consumption, accomplished by the late nineteenth century, was another fundamental but generally overlooked turning point in the history of the business corporation. Understanding this transformation throws light not just on historical practices, but also on contemporary debates over deviations from the rule of one-share-one-vote.
