The cause of America's high health care costs

Harvard economist and John Bates Clark Medal-winner Martin Feldstein identifies the cause of America's high health care costs:

Budget considerations aside, health-economics experts agree that private health spending is too high because our tax rules lead to the wrong kind of insurance. Under existing law, employer payments for health insurance are deductible by the employer but are not included in the taxable income of the employee. While an extra $100 paid to someone who earns $45,000 a year will provide only about $60 of after-tax spendable cash, the employer could instead use that $100 to pay $100 of health-insurance premiums for that same individual. It is therefore not surprising that employers and employees have opted for very generous health insurance with very low copayment rates.

Since a typical 20% copayment rate means that an extra dollar of health services costs the patient only 20 cents at the time of care, patients and their doctors opt for excessive tests and other inappropriately expensive forms of care. The evidence on health-care demand implies that the current tax rules raise private health-care spending by as much as 35%.

The best solution to this problem of private overconsumption of health services would be to eliminate the tax rule that is causing the excessive insurance and the resulting rise in health spending. Alternatively, Congress could strengthen the incentives in the existing law for health savings accounts with high insurance copayments. Either way, the result would be more cost-conscious behavior that would lower health-care spending.

I have previously made the case for greater use of health savings accounts here.
