What is Agency Theory?

Definition

Agency theory is an economic and management theory that explores issues of information asymmetry and conflicts of interest in agency relationships. An agency relationship typically refers to the relationship between a principal and an agent, where the principal hires the agent to perform a task or manage an affair. Since principals and agents often have different goals and risk preferences, and agents may possess more information than principals, this can lead to agents acting in ways that are not in the best interest of the principals. Agency theory analyzes how to design incentive mechanisms and contract arrangements to reduce problems caused by these conflicts of interest and information asymmetry.

Origin

The origin of agency theory can be traced back to the 1970s, particularly the 1976 paper by Michael Jensen and William Meckling titled "Theory of the Firm: Managerial Behavior, Agency Costs and Ownership Structure." This paper systematically analyzed the problems in agency relationships for the first time and introduced the concept of agency costs, becoming a fundamental basis for modern corporate governance theory.

Categories and Features

Agency theory mainly divides into two categories: the agency relationship between shareholders and managers, and the agency relationship between creditors and shareholders. The relationship between shareholders and managers focuses on managers potentially engaging in behaviors that are detrimental to shareholders' interests, such as excessive consumption of company resources. The relationship between creditors and shareholders concerns shareholders potentially taking high-risk investments that harm creditors' interests. Agency theory emphasizes alleviating these issues through appropriate incentive mechanisms and contract terms.

Case Studies

A typical case is the collapse of Enron. Enron's management used complex financial structures and opaque accounting practices to conceal the company's true financial status, ultimately leading to bankruptcy. This is a classic agency problem where management's actions severely harmed the interests of shareholders and creditors. Another case is Apple's shareholder incentive plan. Apple successfully aligned management's interests with long-term shareholder interests through stock options and performance bonuses, reducing agency problems.

Common Issues

Common issues investors face when applying agency theory include how to effectively design incentive mechanisms to ensure agents' actions align with principals' interests and how to monitor agents' behavior to reduce information asymmetry. A common misconception is that all agency problems can be solved through incentive mechanisms, whereas in reality, more complex contract arrangements and monitoring mechanisms are sometimes required.
