Interpreting life expectancy statistics and other health care issues

Matt Yglesias and Paul Krugman weigh in on interpreting life expectancy statistics across the U.S. and the Netherlands.  The fact under consideration, from a few days ago, is that the U.S. has low life expectancy overall but superior life expectancy after you reach the age of 65.

One way to interpret this data (re: Yglesias and Krugman) is to think that the U.S. should spread Medicare to its entire population.

Another interpretation is that spreading Medicare to the entire population would lead to higher expenditures on the health of the young and lower expenditures on the health of the old, for better or worse.  "Medicare for everyone" doesn't simply replicate current Medicare outcomes across a broader swathe of the population.  Medicare works as well as it does, in part, because not everyone is on Medicare or something comparable.  The U.S. split system makes Medicare, at the same time, both more effective in terms of outcomes and more costly in dollar price terms.

In this country the old don't seem willing to accept losing their privileged "first in line" position, namely Medicare for them and few others.  And Congress won't let some egghead committee come along and cut the waste out of Medicare.  The immediate results of the current proposed plan would thus be greater health care expenditures overall, pressures on doctor supply a' la Massachusetts, an even more severe long-term insolvency for the whole system, combined with an unclear resolution for all these escalating pressures.  I don't see many people on the pro-Obama side simply coming out and admitting these increasingly obvious truths, although Andrew Sullivan deserves credit on this score.

You may or may not think that's a good deal overall and perhaps you still think it's a good deal if you assign a high enough priority to covering more of the uninsured.  Or maybe (Kevin Drum has made this argument) you think it's the only path toward long-run cost control.  But if you think it's a bad deal overall, it doesn't mean you are in denial about the fundamental facts of U.S. health care supply or for that matter in denial about the cross-sectional comparisons with Europe.  Choosing French health care institutions for the United States has never been on the table, not even in evolutionary terms.

Sullivan put it very well a few days ago.  He noted that Obama — a master communicator — can't convince most people that the proposed reform is a good deal for them because…it isn't a very good deal for most people. That includes some of the people receiving new coverage, such as those receiving the new forced employer mandates.  (NB: Their wages will go down and they really need the money!  In the shorter run their wages won't go down and some of them will lose their jobs, even with phase-in a few years from now.  I'm still waiting for good Democratic economists to condemn this idea but I fear there is so much fixation on a "victory vs. defeat" framing of the struggle, and desire to skirt the CBO, that this isn't receiving the critical analysis it ought to.)

This desire to claim and promote a more universal distribution of benefits is one reason why you see so much attention paid to the public plan option.  The competing public plan at least offers the promise that some part of the proposed health care reforms will benefit virtually everyone.  My view is that a public plan would soak up many high-risk cases, benefit those cases and few other people, and that overall a public plan is superior to mandates, not Satan incarnate, but not a cure-all for the system as a whole by any means.  Advocates remain oddly silent as to what in concrete terms the public insurer will be instructed to maximize and how that fits in with pressures to extend coverage to more people.

Plan supporters are quite willing to admit "it's not nearly as good as what we wanted," but they're in denial about how truly bad the proposed reforms are in absolute terms or as a matter of economic logic and by that term I mean the economic logic of good Democratic economics, not extreme libertarianism.

In the meantime, repeat this sentence after me: if we don't solve the costs problem, in egalitarian terms things will only get worse, no matter how many people we cover.

The Republicans on this issue are (mostly) very bad and hypocritical but that doesn't give the Democrats license to proceed without a solution.

From the comments: who lives longer?

Adam reports:

At birth, someone living in the Netherlands can expect to live 2.35
years longer than someone born in the US, but at age 65, the difference
is reversed, and someone living in the US can expect to live 0.4 years
longer than someone living in the Netherlands. This difference can be
explained by assuming that semi-socialized health care is better for
young and worse for old people, or, at least as likely, different
policies are not the main cause of the difference

One interesting feature of this data is that it can be used to argue for a number of different points of view.

Will health care reform happen? A simple guide

I presented the following theory to two notable health care commentators a few nights ago.  Congressmen are looking to sell their voters for the highest "price" possible and they know Obama really wants, and indeed needs, to win a health care victory.  As health care reform "falls apart," these Congressmen face the risk that they will get nothing for those votes.  Suddenly their cartel falls apart and they lower the price for those votes.  A deal is then possible and Obama buys the votes at the lower price.

What appears to be pessimistic news for health care reform can in fact be optimistic news.  Another implication of this theory is that a lot of the "news" along the way, concerning the fate of reform, is simply noise.

I don't know what is the "p" of an extended coverage bill passing, but I believe that p has stayed fairly constant so far.

There are plenty of games in which the equilibrium and the true offer curves are not revealed until the final period.  When it comes to health care, we're not yet at the end.

Interview with Kenneth Arrow

With Conor Clarke, it's about his classic paper on health care.  Excerpt:

…the question that I started with was why health insurance coverage was
limited. There was virtually no insurance outside of hospitalization,
which was limited and heavily taxed. When I heard about this myself, it
was just as a consumer. My first health-care plan as a professor had a
$15,000 ceiling. A ceiling? I was thinking that should be a floor!
$15,000 I can handle, but above that… it would be a problem.

The most interesting segments are the (hard-to-excerpt) remarks on the erosion of professional standards in medicine.

By the way, what will life expectancy be when population is infinite?

The effect of community rating in health insurance markets

Maybe there's been enough discussion of Paul Krugman on health care but still this caught my eye.  In a recent blog post Krugman wrote:

The reason we have restrictions on interstate sales of health insurance is that a number of states regulate insurers. In particular, some states have a form of community rating, which basically says that insurers can’t deny you coverage or charge extremely high premiums if you have a preexisting condition. And community rating will be unsustainable if individuals can buy insurance from out of state; insurance companies in states that don’t have community rating will cherry-pick the healthy, good risk people, leaving the community rating states with only the highest-cost people.

Krugman's post seems to be very approving of such community rating.  When it comes to California, which has no community rating, "insurers compete by doing their best to deny coverage to anyone who might actually need medical care."

Based on a close look at the data, Herring and Pauly write (I can't find an ungated version can you?):

Some states have implemented community rating regulations to limit the extent to which premiums in the individual health insurance market can vary with a person's health status. Community rating and guaranteed issues laws were passed with hopes of increasing access to affordable insurance for people with high-risk health conditions, but there are concerns that these laws led to adverse selection. In some sense, the extent to which these regulations ultimately affected the individual market depends in large part on the degree of risk segmentation in unregulated states. In this paper, we examine the relationship between expected medical expenses, individual insurance premiums, and the likelihood of obtaining individual insurance using data from both the National Health Interview Survey and the Community Tracking Study Household Survey. We test for differences in these relationships between states with both community rating and guaranteed issue and states with no such regulations. While we find that people living in unregulated states with higher expected expense due to chronic health conditions pay modestly higher premiums and are somewhat less likely to obtain coverage, the variation between premiums and risk in unregulated individual insurance markets is far from proportional; there is considerable pooling. In regulated states, we find that there is no effect of having higher expected expense due to chronic health conditions on neither premiums nor coverage. Overall, our results suggest that the effect of regulation is to produce a slight increase in the proportion uninsured, as increases in low risk uninsureds more than offset decreases in high risk uninsureds [emphasis added by TC]. Community rating and guaranteed issue regulations produce only small changes in risk pooling because the extent of pooling in the absence of regulation is substantial.

You'll find some unadjusted raw data for states here

Herring and Pauly, who wrote this paper in 2006, stress that what I am describing as the Krugman view is the "conventional wisdom" yet not supported by the facts.  More generally, you can think of their excellent paper is a contribution to the ongoing debate over health insurance and adverse selection.  As the authors say "there is considerable pooling."

I am not, by the way, suggesting that we should move everything to the individual insurance market or that Jim DeMint is an objective analyst of U.S. health care.

European health insurance bleg

Yana is moving to Paris for the fall semester and some (but not all) family members believe that she should buy additional health care insurance for this event.  I fear this is a market which does not work very well, since so many customers don't file claims or have repeated interactions with the company.  So I ask you all — and thank you in advance — for advice on the best way to make this transaction and find a reliable company.  Web evaluations of the leading suppliers are not obviously impressive and she won't have a French institution to cover her with a local program.

This is a post rich in health care economics, I am sorry to say.  And I know how much you all love health care economics.

Examples of free market health care

There are, however, no examples of successful health care based on the
principles of the free market, for one simple reason: in health care,
the free market just doesn’t work.

That's Paul Krugman.  I would frame this point a little differently.  There are in fact plenty of people who buy their health care in a more or less free market setting, most of all in Latin America but all over the world.  It's far from obvious that these markets fail in efficiency terms ("compared to what?" is the obvious follow-up).  For the wealthy in Latin America these markets seem to work well.  They work much less well for the poor but is that because of market failure or because these poor simply don't have much money to spend?

One possibility is that the main problem with these markets is distributional rather than efficiency.  (Krugman's third paragraph recognizes this, but he doesn't use the point to reorganize the analytics of his critique.  Also note some tricks.  When markets fail at providing insurance, ex ante this is a possible efficiency problem but ex post it will be a problem of distribution.)

Another way to state the health care problem is this: once we try to obtain distributional objectives, supply becomes less efficient.  That understanding might focus your attention on a voucher-like system, combined with deregulation. rather than government interference in provision.  Another option is for government to provide nudges to have better monitoring of HMOs or insurers, to make them more trustworthy.  Or maybe catastrophic-only insurance, to overcome the distributional problem where it is most severe.

You can understand the French system by citing the incentive for overtreatment and now we are back to the possibility of efficiency being the primary problem.  If you limit overtreatment, by organizing doctors into poorly paid, fixed salary co-ops, you keep costs down and make some parts of the distribution problem easier to solve. 

There are plenty of health care services in this country, such as laser
eye surgery
, or plastic surgery, which are supplied in more or less
market settings.  I don't consider their efficiency an open and shut case, but it's quite possible we'd be delighted if other areas of health care worked this well in terms of cost-lowering and innovation and even availability.  It could be that these services are more transparent or it could be they are simply less regulated and further removed from third-party payment.

Read this post of Bryan Caplan's and ask yourself whether the Arrow problems are in fact what motivate most of the health care intervention we observe in the U.S.  Maybe France is the country which took Arrow seriously.

It makes a difference whether you view the case against the market as starting with issues of efficiency or distribution and usually those concepts are jumbled together.

Sometimes I wonder how wealthy we all would have to be before we could just pay cash for our health care.  I call this the Pablo Escobar solution.  It's a long way away but is it imaginable at all?  Does it recede as we approach it?  Do we have to give up some distributional objectives to ever get there?  Do we simply embrace it when the poverty line is defined as standing at $200,000 a year?

Don’t take this the wrong way

The prospects for health care reform seem to be dimming.  If I were a progressive I would be wondering right now whether Medicare was a tactical mistake.  The passage of Medicare meant that most old people get government-provided health care coverage.  Yet the way to get things done in this country, politically, is to get old people behind them.  Further health care reform doesn't now seem to promise much to old people, except spending cuts on them.  Given their limited time horizons, old people don't so much value system-wide improvements, which invariably take some while to pay off.

If Medicare had not been passed, might this country have instituted universal health care coverage sometime in the 1970s?

Health care and them annie-mules, update

Anyway, when you look at the increase in spending per
capita, health care spending per person rises by 350 percent, vet
spending per dog rises by 335 percent, and vet spending per cat rises
by 340 percent..  So on this one, I think the conservatives have the
better argument, despite the flaws in the original evidence.

That is Scott Winship, here is more.  Little did the blogosphere guess that this topic would turn so popular.  I also liked the comment from the guy who wondered about the aging of America's pet population and whether illegal pet immigration might remedy the associated fiscal problems.

Questions which are rarely asked

Today it is from Megan McArdle:

Veterinary spending is rising just about in line with human medical
spending.  Kudoes to AEI for publishing a graph that seriously
undercuts one of the major conservative arguments about health care: 
that the main problem is consumers who don't bear their own costs. 
Veterinary spending is subject to few of the perversities that either
left or right suppose to be the main problems afflicting health care
spending.  Consumers pay full frieght most of the time.  They are price
sensitive, and will let the patient die if keeping him alive costs too
much.  There is no adverse selection.  There is no free riding on
mandatory care.  Government regulation is minimal.  Malpractice suits
are minimal, and have low payouts.  So why is vet spending rising along
with human spending?

There is a very nice graph in the post.

*A Brain Wider than the Sky*

The author is Andrew G. Levy and the topic is migraine headaches:

Even more remarkably, triggers seem to be culturally particular.  French migraine researchers, testing a French population, found widespread complaints about white wine and chocolate.  British researchers, testing their own countrymen and women, found red wine and cheese to be the more potent triggers.  Such anomalies might point to flaws in the studies, but more likely, they point to something mysterious about the human temperament that migraine reveals.  It's not the chemical in the wine that triggers the migraine generator, but something else inside the wine entirely, something in what the wine means to the drinker — something that might change by region, by individual, by culture, that simply obliterates the border between the somatic and the psychosomatic.

The subtitle is A Migraine Diary and you can buy this very interesting book here.  Levy outlines his struggle with migraines, their possible roots, and what they reveal about the broader human condition.  According to Levy, Asians and African-Americans are less prone to migraines and the differences may be partly genetic in origin.

Kidney Donor Chains

Virginia Postrel has an excellent piece in the online Atlantic on the shortage of transplant organs, it includes a very good discussion of both the promise and limitations of kidney swaps and donor chains.  Imagine that Mrs. Smith and Mr. Jones each need a kidney transplant.  Mr. Smith is willing but due to an incompatible blood type unable to donate a kidney to his wife.  Similarly, Mrs Jones is willing but unable to donate a kidney to her husband.  In a kidney swap, Mr. Smith donates to Mr. Jones and Mrs. Jones donates to Mrs. Smith.  Everyone is happy.

Donor chains extend this idea.  We start with an altruistic donor willing to give to anyone – by careful arrangement it's then possible to produce many transplants.  Recently, a single donor led to a chain of ten transplants!

Despite the promise of these techniques they are being underutilized.  Amazingly, the National Kidney Registry, which coordinates swaps and chains, has donors who are waiting to give.  A clear reminder that $500 bills aren't always picked up as quickly as we would like. 

Even the maximal use of swaps and chains won't solve the crisis, however. For that we are going to need better incentives to encourage more donors.

Administrative Costs

In the latest debate: Paul Krugman attacks Greg Mankiw for linking to a study by Robert Book arguing that administrative costs under Medicare are not as low as many people think.  Book defends against Krugman's attack here.  I find the debate peculiar for a number of reasons:

1)  Picking out one measure of health care "costs" to compare systems is sadly reminiscent of the arguments for socialism.  Do you remember those arguments?  Under socialism:

  • "Think of how much money we will save on advertising!"

  • "Socialism will lower costs by maximizing economies of scale!" 

  • "Money will be used for production not profits!"

Exactly these arguments are regularly trotted out in the debate over administrative costs in health care so color me unimpressed.  To be clear, the point is not that these statements are false – the point is that these premises to the argument are all in some sense true it's just the conclusion, socialism is more efficient than capitalism, which turned out to be false.  We tried that and it didn't work. In other words, you have to compare systems not arbitrarily pick out for comparison one type of costs.

2)  Closely related to this point is the bizarre habit of taking about costs without mentioning benefits.  The implicit argument appears to be that administrative costs are simply waste – this is the ancient cutting out the middleman fallacy.  Administrative benefits, for example, reduce fraud and are a necessary consequence of making it easy for patients to get second and third opinions from different doctors.

3)  Even if we could switch from a private to a public system and save administrative costs, the deadweight costs of taxation will far exceed any reasonable savings.

4)  Any savings on administrative costs is a one-time level effect but the real issue with health care costs is growth as a share of GDP.  (By the way, this same point explains why the debate over whether the public plan will discipline private monopolies is not especially important, monopoly–even if it is a  problem–could at best explain a level effect not a growth effect which is where the action is.)

5)  I'm not surprised that administrative costs under Medicare and under Canada's system suggest some potential cost reductions from moving to a single-payer system–again, Lada did save on marketing expenses–but it's a complete blunder to use Medicare administrative costs as an argument in favor of a "public option."  The whole point of the public option, so we are told, is to compete on a level footing with private plans which means marketing expenses and all the rest.     

Addendum: n.b. this post is about administrative costs not other reasons for preferring one system to another.  See also Tyler on administrative costs further below.
