Principal Agent Theory Of The Firm Essay

The principal-agent problem occurs when a principal delegates an action to another individual (agent), but the principal does not have full information about how the agent will behave. Secondly, the interests of the principal diverge from that of the agent, meaning that the outcome is less desirable than the principal expects.

Shareholder and manager

For example, a shareholder (principal) wants to maximise profits for his firm. He hires a manager (agent) to run the business. However, due to agency costs, the shareholder cannot fully know how hard the agent is working and to what extent the manager is fulfilling the contract. Also, in this situation, the manager does not share the same interest in maximising profits as the owner.

Market failure

The principal-agent problem can lead to market failure because the agent pursues his own self-interest rather than that of the principal and the business may be run in an inefficient way. In extreme cases, the mutually beneficial action may not happen because the principal lacks information.

The Principal-agent problem can also cause adverse selection – poor choices based on asymmetric information. This is where the agent has private information before a contract is written. For example, a lazy worker gets a job because the employer doesn’t know he is lazy.

Requirements of principal-agent problem

  • Multiple actors who have a different set of objectives (e.g. shareholders vs workers.
  • Asymmetric information (the agent having more information than principle.) The shareholder can see some stats like profit, but only the manager knows exactly how hard he worked or didn’t.

Examples of Principal-Agent Problem

Shareholders and managers of a company. Shareholders will wish to maximise a firm’s profits to increase their dividends. However, the manager and workers, who are responsible for day to day running of the firm, may fail to pursue profit maximisation. Instead, they concentrate on enjoying work and getting on with workers.

Landlord and tenant. The landlord owns house and rents out to tenants. He asks tenants to take care of the property and minimise electricity bills. But, tenants may open windows rather than turn down the heating.

Sub-contracting your essay. Suppose a lazy student paid a random stranger on the internet to write a dissertation. Apart from being cheating which could lead the student to be expelled, it is also an example of a principal-agent problem. The lazy student pays $500 for the essay, but the person writing the essay in anonymity has not the same motivation and may not care about the quality. They will gain $500 whatever happens to the grade.

Principal-Agent Problem and Moral Hazard

The principal-agent problem can also lead to an individual taking an excessive risk because the ultimate cost is borne by someone else. This is an example of moral hazard.

For example, an investment banker may gain a bonus for making high profits. This encourages the banker to take risky investments. If he fails and loses $700m, the losses are absorbed by the bank (or taxpayer) – not by the individual banker. This has led to major banking collapses, such as rogue trader Nick Leeson and Barings Bank (1995).

Costs of Principal-Agent Problem

Agency costs. Due to information asymmetries, principals may be unaware of how much a contract has been fulfilled. Principals may be reluctant to enter into a contract at all for the fear that they will not know what is going on. For example, a landlord may be reluctant to lend if he fears that a tenant may mistreat his property and be unable to know how it is cared for. If a mutually beneficial transaction doesn’t occur at all, this would be a significant welfare loss.

“We define an agency relationship as a contract under which one or more persons (the principal(s)) engage another person (the agent) to perform some service on their behalf which involves delegating some decision making authority to the agent. If both parties to the relationship are utility maximisers, there is good reason to believe that the agent will not always act in the best interests of the principal.”

Theory of the Firm: Managerial Behavior, Agency Costs and Ownership StructureJensen and Meckling (1976)

Inefficiency. Principal-agent problem enables agents to produce sub-optimal work. For example, managers may be profit-satisfiers – leading to higher costs and less profit.

Cost of monitoring/incentives. To try and overcome the principal-agent problem, the principal will have to spend money on monitoring and providing incentives for workers.

“However,  it  is  generally  impossible  for  the  principal  or  the  agent  at  zero  cost  to  ensure  that  the agent will make optimal decisions from the principal’s viewpoint.”

Jensen and Meckling (1976)

Overcoming Performance Related Pay

Tipping. Waiters who rely on tips for pay will have their interests more aligned with owners (principals). This can be an effective way to remove the principle-agent problem. However, due to social conventions, it is difficult to move away from tipping in all but the limited industries of restaurants and cafes

Performance Related Pay. A simple solution to give agents an incentive to work hard. However, it depends on how Performance Related Pay is implemented. Without sufficient flexibility, it can create tension in the workplace and reduce co-operation. Also, some jobs are suitable for objective evaluation, e.g. fruit pickers have an easily quantifiable output. But, other jobs, such as teaching and managers require more subjective evaluation.

Different workplace environment. Workers are motivated by a variety of factors other than pay. Some of the main motivations are not pay, but pride in work and a sense of achievement. A management structure which encourages independence and workers taking responsibility for work can be more effective than crude pay bonuses.

ONE morning, an economist went to buy a shirt. The one he chose was a marvel of global production. It was made in Malaysia using German machines. The cloth was woven from Indian cotton grown from seeds developed in America. The collar lining came from Brazil; the artificial fibre from Portugal. Millions of shirts of every size and colour are sold every day, writes Paul Seabright, the shirt-buying economist, in his 2004 book, “The Company of Strangers”. No authority is in charge. The firms that make up the many links in the chain that supplied his shirt had merely obeyed market prices.

Throwing light on the magic of market co-ordination was a mainstay of the “classical” economics of the late-18th and 19th centuries. Then, in 1937, a paper published by Ronald Coase, a British economist, pointed out a glaring omission. The standard model of economics did not fit with what goes on within companies. When an employee switches from one division to another, for instance, he does not do so in response to higher wages, but because he is ordered to. The question posed by Coase was profound, if awkward for economics: why are some activities directed by market forces and others by firms?

His answer was that firms are a response to the high cost of using markets. It is often cheaper to direct tasks by fiat than to negotiate and enforce separate contracts for every transaction. Such “exchange costs” are low in markets for standardised goods, wrote Coase. A well-defined task can easily be put out to the market, where a contractor is paid a fixed sum for doing it. The firm comes into its own when simple contracts of this kind will not suffice. Instead, an employee agrees to follow varied and changing instructions, up to agreed limits, for a fixed salary.

Coase had first set out his theory while working as a lecturer in Dundee, in 1932, having spent the prior academic year in America, visiting factories and businesses. “The nature of the firm”, his paper, did not appear for another five years, in part because he was reluctant to rush into print. Though widely cited today, it went largely unread at first. But a second paper, “The problem of social cost”, published in 1960, by which time he had moved to America, brought him to prominence. It argued that private bargaining could resolve social problems, such as pollution, as long as property rights are well defined and transaction costs are low (they rarely are). He had been asked to expound his new theory earlier that year to a sceptical audience of University of Chicago economists. By the end of the evening, he had won everyone around. Coase was invited to join the university’s faculty in 1964; and there he remained until his death in 2013 at the age of 102.

In 1991 Coase was awarded the Nobel prize for economics, largely on the strength of these two papers. But as late as 1972, he lamented that “The nature of the firm” had been “much cited and little used”. In a strange way, Coase himself was partly to blame. The idea of transaction costs was such a good catch-all explanation for tricky subjects that it was used to close down further inquiry. In fact, Coase’s paper raised as many difficult questions as it answered. If firms exist to reduce transaction costs, why have market transactions at all? Why not further extend the firm’s boundaries? In short, what decides how the economy as a whole is organised?

Almost as soon as Coase had wished for it, a body of more rigorous research on such questions began to flourish. Central to it was the idea that it is difficult to specify all that is required of a business relationship, so some contracts are necessarily “incomplete”. Important figures in this field include Oliver Williamson, winner of the Nobel prize in economics in 2009, and Oliver Hart and Bengt Holmstrom, who shared the prize in 2016. These and other Coase apostles drew on the work of legal theorists in distinguishing between spot transactions and business relations that require longer-term or flexible contracts.

Spot markets cover most transactions. Once money is exchanged for goods, the deal is completed. The transaction is simple: one party wants, another supplies. There is little scope for dispute, so a written contract can be dispensed with. If one party is unhappy, he will take his business elsewhere next time. Spot markets are thus largely self-policing. They are well suited to simple, low-value transactions, such as buying a newspaper or taking a taxi.

Things become trickier when the parties are locked into a deal that is costly to get out of. Take a property lease, for instance. A business that is evicted from its premises might not quickly find a building with similar features. Equally, if a tenant suddenly quit, the landlord might not find a replacement straight away. Each could threaten the other in a bid for a better rent. The answer is a long-term contract that specifies the rent, the tenure and use of the property. Both parties benefit.

But for many business arrangements, it is difficult to set down all that is required of each party in all circumstances. In such cases, formal contracts are by necessity “incomplete” and sustained largely by trust. An employment contract is of this type. It has a few formal terms: job title, work hours, initial pay and so on, but many of the most important duties and obligations are not written down. It is thus like a “mini-society with a vast array of norms beyond those centred on the exchange and its immediate processes”, wrote Mr Williamson. Such a contract stays in force mostly because its breakdown would hurt both parties. And because market forces are softened in such a contract, it calls for an alternative form of governance: the firm.

One of the first papers to elucidate these ideas was published in 1972 by Armen Alchian and Harold Demsetz. They defined the firm as the central contractor in a team-production process. When output is the result of a team effort, it is hard to put the necessary tasks out to the market. That is because it is tricky to measure the contribution of each member to the finished work and to then allocate their rewards accordingly. So the firm is needed to act as both co-ordinator and monitor of a team.

Chain tale

If a team of workers requires a firm as monitor, might that also be true for teams of suppliers? In some cases, firms are indeed vertically integrated, meaning that suppliers of inputs and producers of final goods are under the same ownership. But in other cases, suppliers and their customers are separate entities. When is one set-up right and not the other?

A paper published in 1986 by Sanford Grossman and Mr Hart sharpened the thinking on this. They distinguished between two types of rights over a firm’s assets (its plant, machinery, brands, client lists and so on): specific rights, which can be contracted out, and residual rights, which come with ownership. Where it becomes costly for a company to specify all that it wants from a supplier, it might make sense to acquire it in order to claim the residual rights (and the profits) from ownership. But, as Messrs Grossman and Hart noted, something is also lost through the merger. The supplier’s incentive to innovate and to control costs vanishes, because he no longer owns the residual rights.

To illustrate this kind of relationship, they used the example of an insurance firm that pays a commission to an agent for selling policies. To encourage the agent to find high-quality clients, which are more likely to renew a policy, the firm defers some portion of the agent’s pay and ties it to the rate of policy renewals. The agent is thus induced to work hard to find good clients. But there is a drawback. The insurance firm now has an incentive of its own to shirk. While the agent is busting a gut to find the right sort of customers, the firm can take advantage by, say, cutting its spending on advertising its policies, raising their price or lowering their quality.

There is no set-up in which the incentives of firm and agent can be perfectly aligned. But Messrs Grossman and Hart identified a next-best solution: the party that brings the most to any venture in terms of “non-contractible” effort should own the key assets, which in this case is the client list. So the agent ought to own the list wherever policy renewals are sensitive to sales effort, as in the case of car insurance, for which people tend to shop around more. The agent would keep the residual rights and be rewarded for the effort to find the right sort of client. If the insurance firm shirks, the agent can simply sell the policies of a rival firm to his clients. But in cases where the firm brings more to the party than the sales agent—for example, when clients are “stickier” and the first sale is crucial, as with life insurance—a merger would make more sense.

This framework helps to address one of the questions raised by Coase’s original paper: when should a firm “make” and when should it “buy”? It can be applied to vertical business ties of all kinds. For instance, franchises have to abide by a few rules that can be set down in a contract, but get to keep the residual profits in exchange for a royalty fee paid to the parent firm. That is because the important efforts that the parent requires of a franchisee are not easy to put in a contract or to enforce.

The management of ties between a firm and its “stakeholders” (its customers, suppliers, employees and investors) is another variation on this theme. A firm often wants to put restraints on the parties it does business with. Luxury-goods firms or makers of fancy sound equipment may ban retailers from discounting their goods as a way to spur them to compete with rivals on the quality of their shops, service and advice.

Inside the cubicle

If one of the challenges set by Coase was to explain where the boundary between firms and markets lies, another was for economic analysis not to cease once it reached the factory gate or office lobby. A key issue is how agreements are structured. Why, for instance, do employment contracts have so few formal obligations? One insight from the literature is that a tightly specified contract can have perverse outcomes. If teachers are paid according to test results, they will “teach to the test” and pay less regard to other tasks, such as inspiring pupils to think independently. If chief executives are paid to boost the firm’s short-term share price, they will cut investment projects that may benefit shareholders in the long run.

Mr Holmstrom and Paul Milgrom established that where important tasks are hard to monitor, and where a balance of activities is needed, then a contract should shun strong incentives tied to any one task. The best approach is to pay a fixed salary and to leave the balance of tasks unspecified. A related idea developed by Mr Hart and John Moore is of a job contract as a “reference point” rather than as a detailed map. Another insight is that deferred forms of pay, such as company pension schemes and promotions based on seniority, help cement long-term ties with employees and reward them for investing in skills specific to the relationship.

Coase noted in 1937 that the degree to which the mechanism of price is superseded by the firm varies with the circumstances. Eighty years on, the boundary between the two might appear to be dissolving altogether. The share of self-employed contractors in the labour force has risen. The “gig economy” exemplified by Uber drivers is mushrooming.

Yet firms are unlikely to wither away. Prior to Uber, most taxi drivers were already self-employed. Spot-like job contracts are becoming more common, but flexibility comes at a cost. Workers have little incentive to invest in firm-specific skills, so productivity suffers. And even if Mr Seabright’s shirt was delivered by a set of market-based transactions, the supply chains for complex goods, such as an iPhone or an Airbus A380 superjumbo, rely on long-term contracts that are often “incomplete”. Coase was the first to spot an enduring truth. Successful economies need both the benign dictatorship of the firm and the invisible hand of the market.
