Scenario: You walk onto a used-car lot to buy a car. You are willing to pay up to $15,000 for a car of good quality but you value a lemon at $0.You are now wondering whether you should trust the car dealer regarding the quality of the car. If you choose to trust him, he can choose to cooperate or defect. If you do not trust him, neither will he earn money nor will you be able to buy a car and use it. If you trust him and he cooperates, both of you will gain because the dealer values a good-quality car at $13,000.

In the United States, the bulk of health care spending is paid by health insurance companies. Such a system is also called a third-party payer system where consumers of health care pay a nominal fee and the rest are paid by the health insurance provider.

Consumers fearing that excessive use of health care services may lead to a rise in insurance premiums tend to under-consume health care services.
Physicians concerned that insurance companies may not approve payments tend not to order expensive tests for their patients.
Consumers have an incentive to over-consume health care services because they pay prices well below the cost of providing these services.
