Moral Hazard, Insurance
The Moral Hazard
The Moral Hazard is a Moral Hazard and Insurance scenario. The core lesson: Insurance against bad outcomes makes bad outcomes more likely. You just bought comprehensive car insurance with a $0 deductible. You used to park carefully, check mirrors twice, and avoid tight spots. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.
The situation
You just bought comprehensive car insurance with a $0 deductible. You used to park carefully, check mirrors twice, and avoid tight spots. Do you still?
Background
Moral hazard is the observation that people take more risks when they're insured against the consequences. It applies far beyond car insurance: bailouts make banks riskier, severance packages can make employees less careful, and safety nets can reduce effort. The insight isn't that insurance is bad. It's that every protection against downside risk also reduces the incentive to avoid that downside. The design challenge is providing protection without destroying the incentive to be careful.
What this reveals
Moral hazard: protection degrades caution
Every form of protection against bad outcomes also reduces the incentive to avoid those bad outcomes. Insurance makes people less careful. Bailouts make institutions riskier. Safety nets can reduce effort. This isn't because people are dishonest, it's because they're rational. The design challenge is providing enough protection to prevent catastrophe without destroying the incentive to be careful.
How to counter it: When designing any protection system, insurance, guarantees, safety nets, backup plans, ask: does this protection change the behavior of the people it protects? If yes, build in incentive alignment through deductibles, monitoring, or co-investment.
A question to sit with
Where in your life has a safety net made you less careful? A backup plan, an insurance policy, a guaranteed income, a supportive parent? Was the trade-off worth it?
