What is the main reason that an agency relationship exists in the corporate form of organization?

An agency relationship exists in the corporate form of organization primarily to separate ownership from control. Shareholders (principals) invest in the corporation but typically do not manage its operations; instead, they appoint managers (agents) to run the business on their behalf. This arrangement allows for specialization, as managers can focus on operational efficiency while shareholders benefit from their expertise. However, it also creates potential conflicts of interest, as agents may prioritize their own goals over those of the principals.
