Thinking through how to run companies
Opinion: canonical academic model of governance rarely the best

Limited-liability, privately owned joint-stock companies are the core institutions of modern capitalism. These entities are largely responsible for organising the production and distribution of goods and services across the globe. Their role is both cause and consequence of the revolution in the scale and diversity of economic activity that has taken place over the past two centuries.
Almost nothing in economics is more important than thinking through how companies should be managed and for what ends. Unfortunately, we have made a mess of this. That mess has a name: it is “shareholder value maximisation”. Operating companies in line with this belief not only leads to misbehaviour but may also militate against their true social aim, which is to generate greater prosperity.
I am not the first person to worry about the joint-stock company. Adam Smith, founder of modern economics, argued: “Negligence and profusion . . . must always prevail, more or less, in the management of the affairs of such a company.” His concern is over what we call the “agency problem” – the difficulty of monitoring management. Others complain that companies behave like psychopaths: a company aiming at maximising shareholder value might conclude it would be profitable – and so perhaps even its duty – to pollute the air and water if allowed to do so. It might also use its resources to obstruct an appropriate regulatory response to such (mis) behaviour.
Question of protectionThe economic argument for shareholder value maximisation and control is that, while all other stakeholders are protected by contract, shareholders are not. They therefore bear the residual risk. This being so, they need to control the company in order to align the interests of management with their own. Only then would they be prepared to make risky investments.
Yet, while shareholders do bear risks in their role as the insurers of solvency, they are not the only stakeholders to do so. A host of others are also exposed to risks against which they cannot be fully protected by contract: long-term workers; long-term suppliers; and, not least, the jurisdictions in which companies operate.
Moreover, shareholders, unlike others, particularly employees, can hedge their risks by diversifying their portfolios. A worker cannot normally work for many companies at the same time and nobody can hedge employee income by owning shares in other people, except via taxation.
The doctrine of shareholder value maximisation has allowed us to believe that the existence of these long-lived, hierarchical and powerful entities has not changed the market economy fundamentally. But, as Colin Mayer of Oxford’s Saïd Business School argues in his splendid book, Firm Commitment, this approach also misses the true purpose of the company. Companies, argues Prof Mayer, are a mechanism for sustaining long-term commitments. But such commitments will only work if it is costly for the parties to act opportunistically. Moreover, it is often in the interests of all parties to bind themselves not to behave in such a way. But, with an active market in corporate control, such commitments cannot be made. Those who make the promises may disappear before they can deliver.
