Shareholder value maximization is the law. It ought to be the law. This is, in part, because the chief alternative available in liberal democratic societies – stakeholder capitalism – is fundamentally flawed. If executives such as those who signed the Business Roundtable’s 2019 statement on corporate purpose really tried to run their companies according to the altruistic principles laid out therein, they would find it an impossible task. Developing the set of objective and quantifiable metrics necessary to operationalize stakeholder capitalism will prove an intractable problem. Even if the requisite set of metrics could be designed, boundedly rational managers cannot reasonably be expected to balance the huge number of competing factors necessary to account for the varied interests of the firm’s many constituencies.
