Principal-agent problems occur when one party (the principal) delegates decision-making authority to another party (the agent), leading to potential conflicts of interest and misalignment of goals. This situation often arises when the agent has more information about their actions than the principal, resulting in a risk that the agent may act in their own interest rather than that of the principal. These problems are significant in contexts where performance is difficult to monitor and can lead to moral hazard, where an agent takes on excessive risks because they do not bear the full consequences of their actions.
