Agency cost

An agency cost is the cost incurred by an organization that is associated with problems such as divergent management-shareholder objectives and information asymmetry.

The information asymmetry that exists between shareholders and the Chief Executive Officer is generally considered to be a classic example of a principal-agent problem. The agent (the manager) is working on behalf of the principal (the shareholders), who does not observe the actions of the agent. This information asymmetry causes the agency problems of moral hazard and adverse selection.

According to Ross and Westerfield (Corporate Finance, 7th edition): when a firm has debt, conflicts of interest arise between stockholders and bondholders. Because of this, stockholders are tempted to pursue selfish strategies, imposing agency costs on the firm. These strategies are costly, because they lower the market value of the whole firm. These strategies may be: 1. Incentive to take large risks; 2. Incentive toward underinvestment; 3. Milking the property.

There are various actors in the field and various objectives that can incurr costly correctional behaviour. The various actors are mentioned and their objectives are given.

Management

Management, specifically the CEO, has their own objectives to pursue. The classical ones are empire-building, risk averse investments and manipulating financial figures to optimize bonusses and stockprice-related options. The latter may be just outright fraudulent, but the first two certainly aren't. They erode the stockholders value, but a risk averse strategy is not by definition fraudulent.

Bondholders

Bondholders typically value a risk averse strategy since that will increase the chances of getting their investment back. Stockholders on the other hand are willing to take on very risky projects. If the risky projects succeed they will get all of the profits themselves, whereas if the projects fail the risk is shared with the bondholder.

Bondholders know this of course, so they will have costly and large ex-ante contracts in place prohibiting the management from taking on very risky projects should they arise, or they will simply raise the interest rate which in turn increases the cost of capital for the company.

Board of Directors

The board of directors in the literature is typically viewed as aligned with either management or with stockholders, but recent theory suggests that they too have own objectives. A very easy non-executive director is ofcourse valuable to the CEO who gets more leeway, but likewise a very critical non-executive director may be just as valuable to the stockholders. Directors further don't want to be the only ones who are critical towards the CEO, because that increases the chances of being evicted off the board. The behaviour of directors is not well known and the theory is largely scarce on this matter.

Labour

Labour is sometimes aligned with stockholders and sometimes with management. They too share the same risk averse strategy, since they cannot diversify their labour whereas the stockholders can diversify their stake in the equity. Risk averse projects reduce the risk of bankruptcy and in turn reduce the chances of job-loss. On the other hand, if the CEO is clearly underperforming the company is in threat of a hostile takeover which typically leads to job-loss as well. They are therefor likely to give the CEO quite some leeway in taking risk averse projects, but if the manager is clearly underperforming they will likely signal that to the stockholders.

Other stakeholders

Other stakeholders such as government, suppliers and customers all have their specific interests to look after and that might incur additional costs. The literature however mainly focusses on the above categories of agency costs.
