Why a representative’s choices can drift
A principal-agent problem arises when one person or organization (the principal) hires another (the agent) to act on its behalf, but their interests do not perfectly match. The agent usually has room to make decisions, and the principal cannot observe every step. That gap creates an opportunity for choices that benefit the agent more than the person they are supposed to serve.
Imagine a company owner who pays a manager mainly for increasing this year’s sales. The manager may push discounts that boost sales quickly but weaken profits or customer loyalty later. The manager need not be dishonest: the reward simply makes one result more valuable to them than the owner’s broader, longer-term goal.
The information gap makes it hard to prevent
Economists call the difference in what each side can see information asymmetry. A client may not know whether a financial adviser recommended a product because it fits the client’s needs or because it pays the adviser more. A shareholder may see a company’s results but not every decision behind them. Monitoring can help, but it costs time and money—and too much oversight can make an agent less able to use their expertise.
Incentives can narrow the gap
Principals can try to align interests through performance measures, carefully designed pay, audits, disclosure rules, or a chance for agents to share in long-term gains. None is foolproof. A bonus tied to one number can encourage an agent to improve that number while neglecting what it leaves out; monitoring can catch misconduct but may not reveal poor judgment.
The practical challenge is to reward the outcome the principal actually cares about, not just the easiest part to count. That is why a contract’s details can shape decisions long before anyone can tell whether the representative has acted in the principal’s interest.
