00:00Moral hazard in insurance occurs when having coverage changes the insured party's behavior,
00:05making them take on more risk than they would if they bore the full financial consequences themselves.
00:10It arises because the cost of that increased risk-taking is shifted onto the insurer
00:15and ultimately other policyholders through premiums, not because people are inherently
00:20dishonest. It's a structural incentive problem. Concrete examples clarify the mechanism.
00:261. A driver with full comprehensive auto coverage may drive less cautiously or skip routine
00:32maintenance, since accident costs are absorbed by the insurer. 2. A homeowner with flood insurance
00:38may underinvest in preventive measures like elevating utilities, knowing rebuilding costs
00:43are covered. 3. In health insurance, patients with low or no co-pays tend to use more medical services
00:50than those bearing higher out-of-pocket costs, studies from Rance.
00:54Health Insurance Experiment 1970s. ADS found that cost-sharing reduced healthcare utilization
01:01by roughly 25-30% without measurable harm to health outcomes for most enrollees.
01:07The severity of moral hazard varies by context. It's higher when the insured has significant
01:13control over the insured event, health habits, driving behavior, and lower when the risk is
01:19largely external, natural disasters, death from unrelated causes. It also scales with deductible
01:25size and co-insurance rates. Lower cost-sharing generally correlates with higher moral hazard.
01:31Insurers mitigate this through deductibles, co-pays, no-claims bonuses, coverage caps,
01:37and behavior-based pricing, telematics, and auto insurance. This differs from adverse selection,
01:43which concerns who buys insurance, not how insured behavior changes afterward. The two are often
01:49confused but are distinct mechanisms. Practically, when reviewing any policy, check how deductible
01:55and co-pay structures are designed, since they directly indicate how much the insurer expects
02:01moral hazard to affect claims, and by extension, your premium. Finally, remember that everything we
02:07discussed today is for educational purposes only and does not constitute financial advice.
02:12Good luck to everyone, and see you in the next video.
