New Design
We have now successfully moved from Typepad to WordPress; most of the kinks of the move and the new design appear to have been worked out. Here is the place to report, however, any remaining issues that you may be experiencing. By the way, if you are interested in moving your own blog, see here.
Will the government shut down?
Here are the Bookmaker’s odds:
Will the U.S. Congress reach an agreement on the federal spending cut bill for the rest of the fiscal year before March 4th?
YES -140 58%
NO -110 47%[The +/- Indicates the Return on the Wager. The percentage is the likelihood that response will occur. For Example: Betting on the candidate least likely to win would earn the most amount of money, should that happen.]
For the pointer I thank Samuel Arbesman. Why is there no InTrade.com market?
Addendum: InTrade now shows a 39 percent chance of a shutdown before the end of June.
Choice-based Medicare cost controls
Let’s say it’s 2027 and I’ve just turned 65. I fill out a Medicare application on-line and opt for a plan with superior heart coverage (my father died of a heart attack), not too much knee coverage and physical therapy (my job doesn’t require heavy lifting), no cancer heroics (my mother turned them down and I wish to follow her example), and lots of long-term disability.
Is that so terrible an approach? Is it obviously worse than having the Medicare Advisory Board make all of those choices for me?
Over the next few days you will read a lot of “downgrade and dismiss” directed at Paul Ryan and his plan and indeed it is quite possible his proposal is not a workable one (I haven’t read it yet). But don’t fall for the downgrade and dismiss bait, keep on returning to the question of how much individual choice should be allowed into health care cost control. Why not divvy up the cost control work between the Board and some degree of individual choice across Medicare benefits? You don’t have to combine that choice with the cost-increasing aspects of Medicare Advantage-like plans.
Many ACA defenders simply do not want to enter into a debate where the framing is “we’re all for cost control, when it comes to Medicare benefit selection it’s a question of government board vs. individual choice.”
I can think of a few reasons why individual choice will sometimes fail as a method of cost control:
1. Individuals have serious misconceptions about the science, or the badness of a particular condition, even in light of government or other third-party advice. Or perhaps individuals simply do not understand the nature of all of the choices at hand.
2. Perhaps an individual will choose “no coverage for lung cancer,” but the government cannot precommit to the outcome of no coverage. Of course as cost control becomes more pressing, we’ll have to learn precommitment for at least some issues, one way or the other, so this cannot be a decisive objection. The entire premise behind the discussion is that we cannot cover all treatments through government subsidy.
3. Over time, perhaps a government Board can rebalance the mix of coverage better than an individual can. People age, possibly lose some mental faculties, science advances, costs change, and so on.
Those are good arguments. They are good arguments for a mixed system. They are not good arguments for ruling out all individual choice of benefits. They are not good arguments for ruling out a scenario like that outlined in the first paragraph of this blog post.
Here is Megan McArdle on the difference between boards and individual choice:
It seems quite likely to me that vouchers are going to be better at controlling health care cost growth than a central committee. Every committee decision that cuts off a potentially useful treatment (and I’m afraid it can’t all be back surgery and hormone replacement therapy) will trigger a lobbying explosion from affected groups. Each treatment is a decision with a small marginal cost to the taxpayer; it’s in aggregate that they become expensive. Which means that the congressional tendency is always going to be to override–and while there are supposed to be structural barriers against this in the bill, they aren’t very strong . . .
Whereas if you put the decision about what treatments to cover in the hands of the patient, the lobbying you face is to increase the overall value of the voucher. To be sure, this will have a larger (and therefore more powerful) group behind it. But it will also come with an enormous pricetag, making it much harder for our politicians to rationalize the decision.
There are lots of comments from Reihan here. Ezra associates the Ryan reforms with Medicare Advantage. Maybe so, and maybe that’s bad, but we return to how much individual choice should we allow into health care cost control, with or without the cost-increasing aspects of the Ryan plan.
We shouldn’t let “downgrade and dismiss” distract our attention from that fundamental question about individual choice.
Haiti fact of the day
At the time the United States intervened in Haiti in 1994, the U.S. defense budget of $288 billion was 20 times the entire gross domestic product of Haiti.
[TC: And yet we still did not quite achieve our war aims.] That is from the new and interesting book by Sarah E. Kreps, Coalitions of Convenience: United States Military Interventions After the Cold War.
Here are music videos by Sweet Micky, the new President of Haiti. I’ve seen him in concert three times and it was always enjoyable.
Words of wisdom
From Kenneth Rogoff, who understands how suddenly an attack can turn:
Unusually low interest rates currently keep the carrying costs of these debts modest, and make it seem as if the day of reckoning is far off. Sadly, debt can be worked off only slowly, while rates can rise suddenly. Such a rise, if sustained, would be extremely painful for the national budgets of many countries, including those struggling in Europe. Research on sovereign default shows that markets also seldom anticipate problems in advance. By the time they lose confidence, it is too late: the option to tighten from a position of strength has evaporated.

General principles for evaluating Medicare reforms
You’ll be hearing lots about the Paul Ryan entitlement reform proposals, but here are a few more general points to keep in mind:
1. As health care develops, it becomes impossible for Medicare (or Medicaid) to cover every treatment.
2. One reform option has government experts rule which treatments are eligible for coverage, with varying degrees of Congressional input.
3. Another option is to let individuals choose in advance which treatments they will be covered for, and which not.
4. #3 can but need not be bundled with voucher and privatization ideas. Without privatization, the government offers people different Medicare packages and they choose one over the others. Government may also recommend a Medicare benefits package for an individual, without requiring that it be chosen.
5. Most plausible policy reforms involve some mix of expert restrictions (#2 )and individual choices (#3) and the real question is to figure out the right mix of the two approaches. When evaluating #2, do keep in mind the potential input of Congress, if only as a background threat.
6. Does individual choice (#3) make more sense for nursing homes and dental care (preferences really matter?), but maybe expert judgment (#2) makes more sense for cancer treatments (expertise really matters?)? I am not endorsing that comparison, it is simply an example to illustrate the issue at hand.
7. If #5 isn’t being addressed, you’re probably just getting polemics. Obligatory citation of David Hume, commit it to the flames, etc.

What determined the playing length of an audio CD?
Here is one account:
Sony had initially preferred a smaller diameter, but soon after the beginning of the collaboration started to argue vehemently for a diameter of 120mm. Sony’s argument was simple and compelling: to maximize the consumer appear of a switch to the new technology, any major piece of music needed to fit on a single CD…Beethoven’s Ninth Symphony was quickly identified as the point of reference — according to some accounts, it was the favorite piece of Sony vice-president Norio Ohga’s wife. And thorough research identified the 1951 recording by the orchestra of the Bayreuther Festspiele under Wilhelm Furtwängler, at seventy-four minutes, as the slowest performance of the Ninth Symphony on record. And so, according to the official history, Sony and Philips top executives agreed in their May 1980 meeting that “a diameter of 12 centimeters was required for this playing time.”
That is from the new and interesting book by Tim Büthe and Walter Mattli, The New Global Rulers: The Privatization of Regulation in the World Economy, the book’s home page, with free chapter one, is here. Speaking of which, Garth Saloner is another very good South African economist and he is now Dean of Stanford Business School.
The Matchmaker
The Boston Globe’s Leon Neyfakh has a good piece on Alvin Roth:
Roth has always been interested in the idea that sophisticated theories can be used to solve practical problems. As a graduate student at Stanford University, he earned a doctorate in operations research, which uses math to help organizations run more smoothly. Roth was just 19 when he started at Stanford, having quit high school without graduating at the age of 16 and finished Columbia University in three years. At just 22, he got a job as an assistant professor at the University of Illinois, and in 1977, at just 25, he was granted tenure there….
In the years since, Roth has emerged as a rare figure in the academic world: a theorist willing to dive into real-world problems and fix them. After helping the med students, he designed a better way to assign children to public schools — the system now used by both Boston and New York. He also helped invent a system for matching kidney donors with patients, dramatically increasing the number of donations that take place each year. More recently, he and one of his students have been talking with Teach for America about improving the system it uses to deploy volunteers around the country.
… Inspired by Roth’s work, these rising economists are also setting their sights on real-world problems. Some are looking at dating websites; others are interested in how universities could do better at scheduling their students’ classes. Like Roth, all of them envision a world in which economists, as unlikely as it may seem, are recognized as society’s mechanics.
One minor note, kidney exchanges are great but I wouldn’t describe the increases as “dramatic.” We will need, in addition, other ideas to alleviate the shortage of transplant organs.
Healthy living vouchers: will they work?
Matt Ridley writes:
Drawing a direct analogy with the effect of vouchers in the education system, Messrs. Seeman and Luciani suggest “healthy-living vouchers” [TC: book is here] that could be redeemed from different (certified) places—gyms, diet classes, vegetable sellers and more. Education vouchers, they point out, are generally disliked by rich whites as being bad for poor blacks—and generally liked by poor blacks. A bottom-up solution empowers people better than top-down government fiat.
So instead of spending large sums on ads to shame us into better eating habits, spend the money on vouchers handed out to the overweight and let them find whatever provider of goods or services best meets their particular dieting needs. After all, the root causes of obesity are multifarious and new ones are being added all the time—such as diet sodas, gut bacteria, genes, sleep apnea, leptin levels, medication, depression, poverty and peer pressure. So the solutions need to be multipronged, too. What works for you may not work for me.
A few points:
1. How exactly does one identify who deserves the voucher? Or does everyone get them? (Do we at this point need another middleclass entitlement?) How much does the price of the good stuff go up?
2. The vouchers can be resold on secondary markets, as food stamps often are.
3. Portfolio effects: the unhealthy person might go to the gym with a voucher and then “make it up” by performing more of the unhealthy behaviors as recompense.
4. Income effects: if the voucher boosts the real income of the unhealthy person, they may well end up buying more stuff which is bad for them. I don’t see that the proposal calls for a simultaneous, income-neutral scheme of taxation. Buying more bad stuff and also more good stuff is not a wash, which brings us to:
5. It is easier to destroy than to preserve health, which suggests limiting the bad, or persuading individuals to limit the bad, will create more health benefits than encouraging the good.
I’m all for creative thinking here, but it’s hard to see this proposal working. If nothing else, though, it shows why this problem is so hard to solve.
