(Finans) Also sometimes referred to as the principal-agent problem. The difficult but extremely important and recurrent organizational design problem of how organizations can structure incentives so that people ("agents") who are placed in control over resources that are not their own with a contractual obligation to use these resources in the interests of some other person or group of people actually will perform this obligation as promised -- instead of using their delegated authority over other people's resources to feather their own nests at the expense of those whose interests they are supposed to be serving (their "principals"). Enforcing such contracts will involve transaction costs (often referred to as agency costs), and these costs may sometimes be very high indeed
