Corporations enjoy four major benefits over other organization forms such as limited liability, permanency, transferability of ownership, and access to capital. These benefits, however, are available because the corporate structure separates ownership from control. Stockholders, the owners of a corporation, do not directly control the interests of a firm. They hire managers to act on their behalf, the classic principal-agent relationship.
However, the relationship is actually a bit more complicated. The owners do not hire the employees of a company themselves. They actually hire top managers, human resources department, and others to hire people to act on behalf of the owners. This complexity can be illustrated further with the set-of-contracts theory of corporate structures. This theory states that organizational relationships are complex with many potentially conflicting legal and moral obligations to stakeholders. The ability to ensure that principal-relationships positively impact each stakeholder rests on the individual relationships that make up the entire system of agency created by the complexity of corporate relationships.
