If you think of insurance as producing wasteful consumption of medical services, then the fact that there are forty-five million Americans without health insurance is no longer an immediate cause for alarm. After all, it’s not as if the uninsured never go to the doctor. They spend, on average, $934 a year on medical care. A moral-hazard theorist would say that they go to the doctor when they really have to. Those of us with private insurance, by contrast, consume $2,347 worth of health care a year. If a lot of that extra $1,413 is waste, then maybe the uninsured person is the truly efficient consumer of health care.
The moral-hazard argument makes sense, however, only if we consume health care in the same way that we consume other consumer goods, and to economists like Nyman this assumption is plainly absurd. We go to the doctor grudgingly, only because we’re sick. “Moral hazard is overblown,” the Princeton economist Uwe Reinhardt says. “You always hear that the demand for health care is unlimited. This is just not true. People who are very well insured, who are very rich, do you see them check into the hospital because it’s free? Do people really like to go to the doctor? Do they check into the hospital instead of playing golf?”
