Moral hazard

Moral hazard describes the change in behavior that occurs when one party is insulated from the consequences of their actions because another party bears the cost. The term originates in insurance economics, where a policyholder who is fully covered may take more risks than they would if they bore the full cost of failure. But the concept extends far beyond insurance.

In mechanism design, moral hazard is the central problem of post-contractual information asymmetry: how do you design incentives so that agents act in your interest when you cannot observe their actions? In organizational theory, it explains why delegation without monitoring produces inefficiency. In financial regulation, it captures the systemic risk created when institutions are "too big to fail" — the socialization of losses while profits remain private.

The standard prescription is better monitoring or tighter incentives. But the deeper insight is that moral hazard is not always a bug. Social safety nets deliberately create moral hazard to protect individuals from catastrophic risk; the question is whether the benefit of insulation outweighs the cost of distorted behavior. The assumption that moral hazard must be eliminated is itself a moral commitment — one that privileges efficiency over resilience.
