Apologies to Mr. Raz
Overly-trusting Straussians
Once you've internalized the idea that people in your circle are smart and sane but occasionally make ludicrous statements for the benefit of the crowds (call it the Elsinore strategy -- feigning madness), it becomes easy to ignore craziness in your own party, particularly when there's a penalty for suggesting the alternative (see Bartlett and Frum).
In other words, we have something like conservation of cynicism. The Straussian assumes the worst about the masses, but has an excuse to assume the best about allies, even when they give every indication of being crazy and/or stupid. The result is that it has taken smart, sane conservatives far too long to acknowledge what's going on with House Republicans.
The consequences of this lack of cynicism is spelled out in detail in excellent posts by Jon Chait and Paul Krugman.
A view into the queue
-- The worst thing about the Tea Party from a Republican perspective is not the movement's extremism. If a (slightly modified) modified stag hunt is an appropriate analogy, players who decrease the chances of a successful hunt (by demanding you take unpopular positions) and who are disloyal (bolting to third party candidates when offended) are the worst possible allies.
-- When Straussianism makes people insufficiently cynical. Conservative thinkers may have underestimated the danger of a default crisis because they assumed the rhetoric coming out of the Republicans in the house was fodder for the masses rather than sincere statements.
-- Fox News and flawed control systems.
-- Political science models may tell us that spouses don't effect candidates' chances, but how far out of the range of data is Michelle Bachmann's husband?

How to improve health care for the poor
As a result, she has the correct instincts for services that would really assist the poor:
This is actually not inconsistent with other findings. For example, every time we get a health care expansion, people predict large falls in emergency room usage. Supposedly, we'll save huge sums by shifting people from expensive ER visits to cheap primary care sessions. Unfortunately, the savings have been elusive; in Massachusetts, the largest such experiment we have to date, ER visits actually rose.
Why? ER's are much more convenient. The working poor usually have much less flexibility in their schedules than the middle class. They work shifts, they may need a doctor's note to miss work, and if they don't work, they often don't get paid.
Note that this implies a totally different solution to the problem of "non-emergent ER visits": urgent care or "Minute Clinics" that work odd hours. Otherwise, you just cram even more people into the same ER space*. It is easy to come up with "Just So" stories in health care. The reforms always sound wonderful, and the benefits always unfold in a beautifully logical way. Unfortunately, people, and reality, are rarely as predictable as the models.
When you are short of money for food, leaving work to sit in an MDs office is a major sacrifice. If you are here in the Southeast and do not drive then the cost in time to make it via public transit can be huge. I have seen sick days used as a part of evaluations. I have worked in a small business where I was the only person in the store and leaving it would cause a crisis.
If you are dying of a myocardial infarct then leaving your job is clearly the right decision. But I would leg infections that started small . . . and sometimes did not progress. If I was able to get an antibiotics prescription then I'd avoid the ER.
I have tried going to "minute clinics" but they all refuse to treat because it was not on the symptom list. A last minute appointment at an MDs office was a huge issue.
I saw some good signs of improvement in Seattle where they put an urgent care clinic (open until something like 1 am) right next to the ER. I joined that HMO and it made a huge difference in my quality of life when a medical event happened.
These days I am a professor and these issues are lessened. But I think it is worth keeping in mind just how crucial these services can be for the poor, even if they are unpopular with people who work a 9 to 5 schedule.

"Looks like I picked the wrong week to quit sniffing glue"
A busy, busy end of July here on the West Coast, professionally, personally and socially. The movers come tomorrow. Perhaps I can get the OE posting queue moving shortly after that.
Words of Wisdom -- Weekend Edition
In fact, the opposite is true — ask anybody who has experienced both wealth and poverty. When you’re wealthy — when you have a nice capital buffer to absorb mistakes — you don’t worry so much about running risks, and you’re significantly happier than when you’re poor and you have to be much more worried about where your money might end up. Insurance improves living standards, it doesn’t detract from them. Let’s have more of it.

A surprisingly blunt view of finance
My reading of what the ratings agencies have said is that if the GOP somehow manages to force the Democrats to do everything their way, this will not secure our AAA; it will guarantee that we lose it, because it will show that we are currently unable to make the ugly bipartisan compromises that long-term budget balance requires, and raises the risk that sometime in the not-very-distant future, the other party will retaliate by threatening default. That's what Wall Street cares about. Not saving social security. Not lower spending. They just care about getting enough consensus to keep the checks flowing.
I think it is easy to over-estimate ideology among members of wall street because a few of them have decided to spend their wealth on political activism. But, for most businesses (especially in banking), the goal seems to be getting paid and it is worth remembering that. Narrowly averting a disaster is only of limited value if structural incentives (and poor journalism) ensure that it happens again and again.
Why we're where we are
Paul Krugman recently said
And look at what this does to incentives: no matter how badly Republicans behave, they don’t draw condemnation from the Very Serious People. All you get is tut-tutting about how politics is awful, and if only we had a third party to install Mike Bloomberg as
dictatorpresident all would be well.Pundits who won’t call out extremism without pretending that it’s symmetric aren’t a big part of our problem, but they are a part of our problem.
He's wrong. They and journalists like the Washington Post's Felicia Sonmez are a big part of our problem and more; they are a necessary condition for the mess we're in.
Josh Marshall takes an in depth look at this idea here.

Virtuous Circles
But even better is the marketing opportunity that this sort of paywall creates:
Those paying digital subscribers, however, are much more valuable than their subscription streams alone would suggest. They’re hugely loyal, they read loads of stories, they’re well-heeled, and advertisers will pay a premium to reach them. Judging by the second-quarter results, which is admittedly early days, it seems as though total digital ad revenues are going up, not down, as subscriptions get introduced: the holy grail of paywalls.
This is a principle worth keeping in mind -- there are virtuous circles as well as vicious ones. Not only does the NYT get to collect predictable revenue from a steady stream of subscribers (and predictable revenue is worth a lot), it also gets an advertising boost from being able to identify these readers. It's an amazing outcome and I remain delighted that it worked out for them.
Now I wonder if we could try and apply these principles to public health. How can we create incentives where patients identify themselves in ways that save money and are happy to do so? Because when you manage to get these sorts of two for one punches, efficiency is massively improved.

When all of your studies are ecological
By contrast, in England during the same period, the nobility and gentry didn’t conspire with the crown to exempt themselves from taxation. Instead, thanks to a number of factors—greater social solidarity, a keener sense of foreign threats, reforms that made the government itself less corrupt, and the principle of taxation only with the consent of Parliament—the wealthy of England willingly accepted higher taxes on themselves. As a result, government spending in England rose from 11 percent of GDP in the late seventeenth century to 30 percent during some years in the eighteenth century. That’s higher than U.S. federal spending today. These higher taxes on the wealthy in England, Fukuyama notes, “did not, needless to say, stifle the capitalist revolution.”
This is a persistent problem in the evaluation of programs: how do you determine the direction of causality in an ecological study? Did England become wealthy and thus feel free to raise taxes or did raising taxes allow England to prosper and become wealthy? The same issue arises with debating points made closer in time:
The idea that the economy will suffer if we modestly raise taxes on upper-income Americans is belied by recent history: we increased tax rates on the rich in 1993 and the economy created more than twenty-two million jobs; we cut them in 2001 and the economy created fewer than seven million jobs.
But it is clear that there were a lot of confounding variables between the two time periods. Still, it is interesting that most people seem to immediately see a link between raising taxes and lower economic growth. Why are we so sure about this link, given the weak relation seen historically?
It's a really challenging problem and, worst of all, one that data can't really help us with.

Mr. Glass vs. the Patent Troll
Saturday, July 23, 2011
A busy morning
This could be a mistake, argues Paul D. Spudis in “The Case for Renewed Human Exploration of the Moon.” In his study, Spudis argues that Moon exploration could reinvigorate the space program and provide a starting point for future research missions. Spudis suggests using the Moon as a testing ground for new technologies and strategies. He says the Moon’s geological make-up can teach us more about other planets and Earth’s own history. And since it has no atmosphere and a dark sky, the Moon could serve as a better home base for astronomical observation. Furthermore, Spudis specifically makes the case for human exploration, rather than just unmanned missions. As an example, he argues that trained scientists can give context to the evidence they collect, whereas robots just pick rock samples at random. He writes, “[Robots] cannot undertake scientific study, make new observations and let these observations guide subsequent work and iteratively apply the lessons learned to an evolving conceptual paradigm […] Although significant gathering of data can be done with robots, conducting science in space requires scientists.” While Spudis is realistic about the political and financial hurdles, he maintains there’s only one way to prevent NASA’s demise: “We must return people to the Moon.”from TNR

There are trigger issues in which the GOP no longer reflects the thinking of mainstream Americans of either party. In Tuesday's charade as the House put the Tea Party debt legislation to a vote, what we saw was an example of the kind of coalition voting common in Europe, where separate parties arrive at an agreement to govern. There are now essentially three parties in Congress: Democrats, Republicans, and the Tea Party. Reasonable Republicans with a sense of the possible do not subscribe to the Tea Party's implacable ideology, but they feel they must deal with it to placate its zealots. They are essentially in a coalition with a third party.from Roger Ebert
And of course, this.
Different visions of Health Care
It turns out that in the final stages of the debt negotiations, Republicans suddenly added a new demand — a trigger that would end up eliminating the individual mandate in health care reform.
This is telling, in a couple of ways.
First, the health care mandate has nothing to do with debt and deficits. So this is naked blackmail: the GOP is trying to use the threat of financial catastrophe to impose its policy vision, even in areas that have nothing to do with the issue at hand, a vision that it lacks the votes to enact through normal legislation.
Second, this is a demand Obama can’t accept, unless he plans on changing his party registration. Health reform doesn’t work without a mandate (remember the primary? Maybe better not to). And if health reform is undermined, Obama will have achieved nothing. So by adding this demand, Republicans were in effect saying no deal . . .
The alternative interpretation is that there is a large segment of the US population that would rather freedom to choose health care than efficient health care. The focus on individual decisions over public well being has implications on a whole host of medical decisions affecting issues like: disease management, fraudulent medications, antibiotic resistance and so forth.
It is hard to see a clear road forward when there is a legitimate difference in such basic questions of health care organization.
