Today's Must Read, from Paul Krugman

Paul Krugman makes an interesting observation in the case of the lion killing dentist from Minnesota, and it has nothing to do with the ethics of killing things for your personal amusement, and everything to do with the fact that "Skin in the Game" does not work to control healthcare costs:

Wonkblog has a post inspired by the dentist who paid a lot of money to shoot Cecil the lion, asking why he — and dentists in general — make so much money. Interesting stuff; I’ve never really thought about the economics of dental care.

But once you do focus on that issue, it turns out to have an important implication — namely, that the ruling theory behind conservative notions of health reform is completely wrong.

For many years conservatives have insisted that the problem with health costs is that we don’t treat health care like an ordinary consumer good; people have insurance, which means that they don’t have “skin in the game” that gives them an incentive to watch costs. So what we need is “consumer-driven” health care, in which insurers no longer pay for routine expenses like visits to the doctor’s office, and in which everyone shops around for the best deals.

………

But what if even the underlying premise, that individual choice will hold down costs, is all wrong?

As it turns out, many fewer people have dental insurance than have general medical insurance; even where there is insurance, it typically leaves a lot of skin in the game. But dental costs have risen just as fast as overall health spending, and it may be that the reduced role of insurers actually raises those costs. According to the post,

In the rest of medicine, insurers have an important function in limiting costs and promoting quality. The market power of Medicare and major national insurance companies allows them to insist on better rates for their customers when they negotiate with doctors and hospitals.

“There’s been less presence from all kinds of insurance payers in the dental sector,” explained Andy Snyder, who is in charge of oral health at the nonpartisan National Academy for State Health Policy. “Medicare does not cover routine dental services, and private dental coverage is far less common than private medical coverage. So, the dental industry has faced less of the cost containment and quality improvement pressures that the rest of the health care sector’s experienced over the last couple of decades.”

So more skin in the game is not just useless but actually counterproductive.

Bazinga!
