One big reason for this result is that doctors are taught that people should not be able to do such cost-benefit calculations, that anything with possible benefits should be done, that it is in fact unethical to take costs into account.

In our system, insurance pretty much pays whatever the doctor orders. It would be shocking if costs did not constantly increase.

I understand your interest in the moral dyad but there's also some practical and political drivers that are probably even more important. The preferential tax treatment of health benefits held over from WWII (another bad economic decision by FDR's brain trust) has long created an incentive for US companies to offer expanded health benefits in place of real wage increases. I like to say what companies offer is better understood as 'prepaid health care' than true insurance. In that light, the only way to unlock the value of the benefit is to utilize health services even when they are of low to no benefit. The advent of HSAs has pushed us away from that model a little bit but they really should be made universal, and adapted to Medicare/Medicaid. What we actually got wasn't a transition to a more stable and viable system but a reform designed to make providing employer-paid health insurance as painful as possible, the better to Cloward-Piven the system so companies would dump the entire mess back on the government.

While not defending the employers health insurance tax treatment, I have a hard time believing this is a big driver.

For one, I don't think most people value health insurance all that much. Whenever they have a chance to trade insurance for cash, they usually take the cash. Even at a 20%-30% discount, I think most people would take the cash if that were an option.

They take insurance when its free. Insurance is often free because society genuinely thinks it should be free. Such a cultural belief would remain even if you got rid of the favorable tax treatment for employer plans.

The main benefit of employer health insurance to most people is it gets them past pre-existing conditions underwriting. Those that have such conditions value that. Those that don't value that they might need it, and think those that already do deserve subsidy anyway.

If we didn't have employer health insurance we would have something like the Obamacare exchanges. Do they strike you as an improvement?

I understand that most people would take cash instead of insurance but since few people have access to health coverage at a comparable price point it doesn't seem to be an option that many people exercise. At best, you simply retain the cash that would have been paid as your portion of the premium. I don't know if many if any employers actually pass on the employer-paid funds to employees that decline coverage. That's why I focused on the way employer-provided health insurance intersected with Mr Kling's focus on over-usage of healthcare services.

Continuous coverage provisions could still exist, and I believe do exist, outside the employer-paid and group health insurance markets.

There isn't fundamentally anything wrong with the Obamacare exchanges. The problem comes more from the policy coverage requirements and other provisions.

If healthy employees could opt to keep the cash, they would do so. Then the remaining portion of the members would be more expensive, causing a death spiral. It would defeat the purpose of the group experience rating.

I know that libertarians dream of some kind of pre-existing coverage insurance, but all I've ever seen in the area in the real world is failure. The member knows more than you, they will change they behavior based on their incentive structure (many pre-existing conditions are self imposed), future medical costs over the long run are very hard to predict, and now more then ever premium comparison shopping is brutal. Even relatively simple products of this type that I've reviewed have extraordinary loss ratios. Just go look at what happened with Long Term Care Insurance, amongst many other examples.

Insurance works great when you can accurately predict risk and cost, and the member isn't particularly incented to abuse the benefit. That's really hard to do in individual long term medical insurance.

"The problem comes more from the policy coverage requirements and other provisions."

If I could design a plan however I want I would lean out the benefits to skim all the best members and leave the trash for someone else or to be uninsured. Many of the coverage requirements are super dumb, but without any it would just become a game of selection.

An awful lot of insurance is about getting people that don't need it to buy it.

The MRI that has more cost than benefits is thinking in dollar terms, not utility terms. If an MRI means that a doctor can be confident in confirming a diagnosis, or excluding a potential disease, then that reduces uncertainty, which can be a positive in utility terms, even if it is more costly.

One indication that health insurance arrangements, copays, moral hazard and other similar factors are not big cost drivers is that in affluent countries expenditures on pet medicine grow at the same or higher rate as expenditures on human medicine. This is true both in US and in Japan. Health insurance for pets is growing fast but the proportion of insured pets is still small, on the order of 5% in US.

It is hard to do a rational analysis on medical cost when the "costs" are unknown. For example, I had a 4X bypass re-plumbing of my heart with the cost of almost $250K+ if I didn't have insurance. The actual amount paid was about $50K.

If I could have obtained the same price as the insurance company did, it would have been optimal to save the almost 10K per year I was paying for my insurance from age 40 to 64 (24 yrs). I had made the mistake of being diagnosed with a blocked LAD when I was 40 and my insurance went through the roof as Prudential cut my existing contract and put me in a high risk pool.

I was forced to by insurance (very high deductible so most years it covered nothing) to get the "discount" the insurance companies get from the medical providers. Saving $240K to cover my risk would make sense.

We need open fixed pricing if you ever want to do something about medical cost.

I think doctors are in a better position to do cost benefit analysis than patients.

Expand full comment

Doctors are in a TERRIBLE position to do cost-benefit analysis.

1) They are taught that it is unethical to consider money cost when making medical decisions. And the culture of the profession ("do whatever is necessary to fix this problem!") often makes it difficult for them to see the non-monetary costs.

2) They have almost no idea what the money costs are anyway.

Well, those things can be changed with different education. But with all that, they are in a better position than the patient to do the cost-benefit analysis. But professional associations could help by doing the work for the procedures and circumstances that incur the most cost. And Medicare which does negotiate reimbursement rates, could take account of whether the provider's claims are based on good cost-benefit analysis.

No one thing is a silver bullet, but especially not pretending that the patient can choose their care as they do flavors of ice cream.

"Well, those things can be changed with different education." Which would be just about as easy--and as likely--as turning the faculty of Harvard University into libertarians. I do not think you realize how central that feeling it to medical educators. The idea, "I will only do what passes a cost-benefit test" is icky, not respectable, like farting in an elevator. A good person does not go there.

Homophobia used to be the same way. But the point is to see that where we need to go, marginal movements.

I also think it would make a marginal improvement to avoiding war if people were more loving. But it's not in my top 100 of ways to do it.

Well, there ARE a lot of supply side constraints. We could be drawing in many more foreign doctors and residencing more medical students, allowing more use of medical practitioners to do things that do not require 7 years of training. But more fundamentally, DFA, Medicare, and individual doctors need to apply benefit cost analysis to their decisions. I don't think higher co-pays would help very much. If we shifted more people away from health insurance "provided" by their employers and toward individual plans financed with partial tax credits, THAT might help in the long run by living insurance companies to put pressure on health care suppliers to come up with more cost effective innovations.

It seems two changes would have a big effect on health care efficiency and costs: (1) greatly diminish the regulation of health care insurance, and (2) require transparency on health care provider pricing.

On the first point, many people, if they had the option, would opt for real health insurance, i.e., insurance to protect against true financial catastrophe, similar to the way life and property insurance markets operate. Overall, it seems such policies would be much more affordable.

On the second point, people with real health insurance (or no health insurance) would be far more price-sensitive. Health care provider pricing transparency would thus permit something closer to a free market in medicine, with its consequent competition among providers, to develop.

>>Next time you go for an MRI, try to calculate the probability that the result will affect the treatment plan and multiply by the likely benefit of the treatment plan. My guess is that the answer will be much less than the cost of the the MRI.

As John Hall has already pointed out, this is the wrong way to calculate the benefit of the test, because it excludes the value of the information itself. How long do you expect to live? Are you likely to become disabled soon? How much should you be saving for future health and long-term care costs? For most people, this sort of information is extremely valuable.

This is just a basic error in these Robin Hanson-esque arguments about the costs and benefits of health care, and I'm disappointed to see you making it. I don't believe there is anywhere near as much non-beneficial treatment as you suggest, when factors like the long-term planning and peace of mind of the patients are included in the calculus.

"My guess is that the answer will be [the benefits will be] much less than the cost of the the MRI."

That's assuming the hospital actually knows what the costs of the MRI are. I recently had a procedure (not an MRI) that was billed at $4,600. The "negotiated price" that the hospital had with my insurance company was $491. When the actual price paid is 10% of the sticker price, something is way out of line. It seems to me that many hospital prices are not determined in any way similar to that how market prices are determined.

It might be interesting to compare bundling of (a) catastrophic insurance and (b) insulation from costs of non-catastrophic events in two large sectors: (1) health care and (2) autos.

My intuition is that most people choose "insulation" when they buy auto insurance. They choose policies that have low deductibles and broad coverage of non-catastrophic events (glass, minor collisions, etc).

Does auto insurance exhibit anything like coverage of "high cost, low benefit" service, which greatly increases costs in health care?

Here is a website with various aggregate data about auto insurance premiums:

https://www.iii.org/fact-statistic/facts-statistics-auto-insurance

Arnold shows that *insulation from costs* and *high prevalence of high cost, low benefit services* go hand-in-hand in health insurance.

By contrast, auto insurance seems to exhibit substantial insulation, but relatively low prevalence of high cost, low benefit services. This is an empirical question, I'm reporting my impression.

Perhaps "moral dyad" psychology plays little role in the auto-insurance industry. Maybe most people believe that medical patients lack agency, but that car owners/drivers have agency because car owners/drivers usually aren't ill when they have to reckon with property damage and auto-insurance adjusters.

Once a car is fixed, it's fixed. Once a person is healthy...they are never healthy. They are just less sick. Healthcare spending is theoretically infinite.

Should you spend $1,000 a month on car repairs on a care with no problems, no. Should you spend $1,000 a month trying to get your blood sugar down, everyones got an opinion dude.

Similarly understanding the prices and shopping around is easy for regular people.

Lastly, making an auto insurance claims requires you to get in a car accident, not a pleasant option. Claiming term life insurance requires you to die. Making another medical claim is perhaps an inconvenience. And many of the things that lead to medical claims are very pleasant (like sex or eating fatty foods).

There will be no healthcare reform. It will continue to eat larger and larger portions of the economy until a fiscal crisis causes a collapse.

Can you think of any sustainable healthcare system today? Is it in a large democratic western country?

Switzerland? Singapore?

Singapore isn't western and as many people will point out anti-democratic in many big ways.

Switzerland is a rather small country with a unique situation.

These are very admirable systems and I'd basically adopt Singapore's is a had a magic wand. But I don't, none of us do.

I'm basically asking if any of the big guys, USA, Germany, France, UK, (we could probably throw in Japan even if not western), etc have sustainable systems? Do any of them have medical cost trend that doesn't exceed GDP growth? Any any of them not facing huge demographic headwinds to public healthcare in the next few decades and presumably into the far future.

Do we have any reason to believe that this status quo will change? Is it going to become easier culturally or politically to get medical cost trend down to GDP growth anytime in the foreseeable future, let alone lower?

I just don't see it. I wouldn't Bet On It.

Even this most recent "reform" from Manchin is especially depressing, and I don't have a problem with drug negotiation. It's just full of the same bullshit I'm used to seeing, and I doubt it will ever save a dime. The size of the medical sector never goes down.

True for too many “services” influenced or provided by government—medical services but also military services, regulation, and debt?

‘ As individuals, we would like unlimited access to medical services without having to pay for them.’

That’s because since WWII we have been told it is a ‘Right’, provision of healthcare for all the mark of a civilised society, we fear death and are encouraged to believe medical care can eliminate death, that better medical care means a healthier nation, and if only you vote for me I shall ensure you get all the medical care you want, if need be, paid for by somebody else.

By the end of six weeks, assuming adequate supply of fresh water, without any food 100% of the population would be dead. By the end of six weeks without any medical care nearly 100% of the population would be alive.

If only half of what we in developed Countries spend on medical care, were spent on resources to provide cheap food for people in poorer Countries, our health would be measurably better and so would theirs.

Among other unpersuasive arguments, you compare absolute $ out of pocket expenses, not the *share* paid for out of pocket. Because spending per capita is so much higher in the U.S., the average person can pay more in $ than in other countries but have this be a lower share of health spending.
