Principal–agent problem

The principal-agent problem is a special idea in economics. It happens when one person acts for another person.

The person being helped is called the principal. The person doing the work is called the agent. A problem starts if these two people want different things. The agent might choose what is best for themselves instead of the principal. This mismatch in goals can cost the principal money. This loss is known as an agency cost.

This problem often happens because of a gap in information. This is called asymmetric information. The agent usually knows more than the principal does. For example, an agent might have special skills or more time. The principal cannot always see every single action the agent takes. This makes it hard to ensure the work is done right. Sometimes the agent has hidden actions or hidden information. This makes the job of the principal much more difficult.

This theory grew out of economics and institutional theory in the 1970s. There is a debate about who first created the idea. Two thinkers named Stephen Ross and Barry Mitnick both claim they started it. Ross once used a story about picking ice cream flavors to explain it. He said it was like picking a flavor for someone else. However, the most famous work comes from Michael C. Jensen and William Meckling. Their research is used by many people to study risk and uncertainty.

People use many tools to solve this problem. One way is to use money as a reward. In restaurants, diners are principals and waiters are agents. A tip is a reward to help the waiter work hard. But tips can cause new problems for the restaurant owner. A waiter might give too much food to get a bigger tip. Other jobs use commissions or profit sharing to help. Some studies show that profit sharing can raise productivity by 3 to 5 percent.

Rewards do not always have to be about money. Some bosses use praise or recognition to help. This is called non-monetary compensation. It can help workers feel a sense of pride in their work. However, paying people only for performance can sometimes cause trouble. In team jobs, individual rewards might make people less helpful to others. They might focus only on their own tasks instead of the team. Finding the right balance is a very important part of managing people.
