Eugene Fama divides firms into two types: the managerial firm, and the entrepreneurial firm.
The owners of a managerial firm advance, withdraw, and redeploy capital, carry the residual investment risks of ownership and have the ultimate decision making rights over the fate of the firm (Klein 1999; Foss and Lien 2010; Fama 1980; Fama and Jensen 1983a, 1983b; Jensen and Meckling 1976).
Owners of a managerial firm, by definition, will delegate control to expert managerial employees appointed by boards of directors elected by the shareholders (Fama and Jensen 1983a, 1983b). The owners of a managerial firm will incur costs in observing with considerable imprecision the actual efforts, due diligence, true motives and entrepreneurial shrewdness of the managers and directors they hired (Jensen and Meckling 1976; Fama and Jensen 1983b).
Owners need to uncover whether a substandard performance is due to mismanagement, high costs, paying the employees too much or paying too little, excessive staff turnover, inferior products, or random factors beyond the control of their managers (Jensen and Meckling 1976; Fama and Jensen 1983b, 1985). Any paucity in knowledge slows the reactions of owners in correcting managerial errors including slip-ups in the recruitment and the retention of experienced older employees.
The entrepreneurial firms are owned and managed by the same people (Fama and Jensen 1983b). Mediocre personnel policies and sub-standard staff retention practices within entrepreneurial firms are disciplined by these errors in judgement by owner-managers feeding straight back into the returns on the capital that these owner-managers themselves invested. Owner-managers can learn quickly and can act faster in response the discovery of errors in judgement. The drawback of entrepreneurial firms is not every investor wants to be hands-on even if they had the skills and nor do they want to risk being undiversified.
Many of the shareholders in managerial firms have too small a stake to gain from monitoring managerial effort, employee performance, capital budgets, the control of costs and the stinginess or generosity of wage and employment policies (Manne 1965; Fama 1980; Fama and Jensen 1983a, 1983b; Williamson 1985; Jensen and Meckling 1976). This lack of interest by small and diversified investors does not undo the status of the firm as a competitive investment.
Large firms are run by managers hired by diversified owners because this outcome is the most profitable form of organisation to raise capital and then find the managerial talent to put this pool of capital to its most profitable uses (Fama and Jensen 1983a, 1983b, 1985; Demsetz and Lehn 1985; Alchian and Woodward 1987, 1988).
More active investors will hesitate to invest in large managerial firms whose governance structures tolerate excessive corporate waste and do not address managerial slack and error. Financial entrepreneurs will win risk-free profits from being alert and being first to buy or sell shares in the better or worse governed firms that come to their notice.
The risks to dividends and capital because of manifestations of corporate waste, reduced employee effort, and managerial slack and aggrandisement in large managerial firms are risks that are well known to investors (Jensen and Meckling 1976; Fama and Jenson 1983b). Corporate waste and managerial slack also increase the chances of a decline in sales and even business failure because of product market competition (Fama 1980; Fama and Jensen 1983b). Investors will expect an offsetting risk premium before they buy shares in more ill-governed managerial firms. This is because without this top-up on dividends, they can invest in plenty of other options that foretell a higher risk-adjusted rate of return.
The discovery of monitoring or incentive systems that induce managers to act in the best interest of shareholders are entrepreneurial opportunities for pure profit (Fama and Jensen 1983b, 1985; Alchian and Woodward 1987, 1988; Demsetz 1983, 1986; Demsetz and Lehn 1985; Demsetz and Villalonga 2001). Investors will not entrust their funds to who are virtual strangers unless they expect to profit from a specialisation and a division of labour between asset management and managerial talent and in capital supply and residual risk bearing (Fama 1980; Fama and Jensen 1983a, 1983b; Demsetz and Lehn 1985). There are other investment formats that offer more predictable, more certain rate of returns.
Competition from other firms will force the evolution of devices within the firms that survive for the efficient monitoring the performance of the entire team of employees and of individual members of those teams as well as managers (Fama 1980, Fama and Jensen 1983a, 1983b; Demsetz and Lehn 1985). These management controls must proxy as cost-effectively as they can having an owner-manager on the spot to balance the risks and rewards of innovating.
The reward for forming a well-disciplined managerial firm despite the drawbacks of diffuse ownership is the ability to raise large amounts in equity capital from investors seeking diversification and limited liability (Demsetz 1967; Jensen and Meckling 1976; Fama 1980; Fama and Jensen 1983b; Demsetz and Lehn 1985).Portfolio investors may know little about each other and only so much about the firm because diversification and limited liability makes this knowledge less important (Demsetz 1967; Jensen and Meckling 1976; Alchian and Woodward 1987, 1988).
It is still unwise to still suppose that portfolio investors will keep relinquishing control over part of their capital to virtual strangers who do not manage the resources entrusted to them in the best interests of the shareholders (Demsetz 1967; Williamson 1985; Fama 1980, 1983b; Alchian and Woodward 1987, 1988).
Managerial firms who are not alert enough to develop cost effective solutions to incentive conflicts and misalignments will not grow to displace rival forms of corporate organisation and methods of raising equity capital and loans, allocating legal liability, diversifying risk, organising production, replacing less able management teams, and monitoring and rewarding employees (Fama and Jensen 1983a, 1983b; Fama 1980; Alchian 1950).
Entrepreneurs win profits from creating corporate governance structures that can credibly assure current and future investors that their interests are protected and their shares are likely to prosper (Fama 1980; Fama and Jensen 1983a, 1983b, 1985; Demsetz 1986; Demsetz and Lehn 1985). Corporate governance is the set of control devices that are developed in response to conflicts of interest in a firm (Fama and Jensen 1983b).
