U.S. Politics

Sen. John Barrasso (R-WY) has introduced a bill to create prizes for carbon sequestration:

This is how it would work. There would be four different levels of prizes. The first level award would go to the public or private entity that could first demonstrate a design for a successful technology that could remove and permanently sequester greenhouse gases. Second, there would be a prize for a lab scale demonstration project of the technology that accomplishes the same thing. Third, there would be an award for demonstrating the technology to remove and permanently sequester greenhouse gases that is operational at a larger, working model scale. Finally, there would be an award for whoever could demonstrate the technology to remove and permanently sequester greenhouse gases on a commercially viable scale.

It sounds like many important details would be decided by a federal commission. The prizes could have many of the promises and drawbacks of Virgin Earth Challenge.
The first three levels of the prizes appear to create incentives to create designs with little regard for commercial feasibility. If those prizes are large, they might end up rewarding technologies that are too expensive to be worth using. Small prizes might have little trouble with this due to inventors not wanting to spend much money to win the prizes, but I’d still have concerns about inventors paying little attention to reliability and maintenance costs. The fourth level appears more promising.
Bureaucrats are likely to put more effort into clarifying prize rules that the Virgin Earth group did. But it’s unclear whether any approaches that a government agency is likely to recommend will do a decent job of translating the “commercially viable” goal into a clear enough set of rules that inventors will be able to predict how the prizes will be awarded.
My advice for the commission, should it be created, is that it tie the prizes to actual amounts of carbon removed from the atmosphere over some pre-specified period, or to estimates of those amounts derived from a prediction market.

The Politimetrics provides implied probabilities of Clinton or Obama winning in November if they get the nomination, derived from Intrade prices. I’m surprised that it’s been showing recently that the difference in their electabilities has been mostly zero, with occasional indications that Clinton is slightly more electable. Most other sources of information appear to suggest that Obama has more support than Clinton among independents and Republicans.
I just did a little trading to help move the market toward showing Obama as more electable by replacing my small bet against Clinton being nominated with a bet against her becoming president, but the amount I’m willing to trade was small enough that the markets moved in the opposite direction (i.e. showed increased Clinton electability).
What could cause the markets to indicate knowledge that conflicts with what I expect?
It could be that several limitations of Intrade impair market efficiency, such as not making it easy to see what those of us who have noticed the Politimetrics site see, or having margin requirements that are not conducive to exploiting inefficiencies of this nature (even if I were more confident that the market is wrong, the expected return on investment isn’t enough to persuade me to make large trades).
It could be that Obama is sufficiently unusual that there’s more uncertainty in how he will do, so that while the most likely result is that he’d get more votes than Clinton would, there’s a greater chance of a negative surprise with him.
It could be that Clinton is expected to be sufficiently vicious if she’s losing that she would hurt Obama before giving up.
But the history shown on the Politimetrics site has swings that seem unexplained by these guesses.

Book review: Poverty and Discrimination by Kevin Lang.
This book is designed to make you feel less sure of your knowledge, and it succeeds in that goal. That’s a worthy accomplishment, although it provides much less satisfaction than a book that provides a grand vision for solving problems would. At some abstract intellectual level I liked the book, but my gut feelings often told me that reading the book was unrewarding work that I shouldn’t do unless it was assigned reading for a course I needed.
The book will dissatisfy anyone who wants to view politics as a fight between good and evil. For many issues such as the minimum wage, he provides strong arguments that the effects are small enough that we should doubt whether the issue is worth fighting about.
He gives good explanations of why it’s hard to even have clear concepts of poverty and discrimination by providing examples of how seemingly trivial or unobservable differences can create results that our intuitions say are important to our moral rules.
He provides clear evidence that some discrimination still exists, and then thoroughly explains why there’s large uncertainty about how harmful it is. He presents one moderately unrealistic model in which discrimination is common but doesn’t affect wages. Then he presents a somewhat more realistic model in which a tiny bit of discrimination produces large wage differences. But those wage differences may overstate the harm done, because they’re partly due to minorities spending less on education and to women pursuing careers in lower risk occupations or careers which allow more flexibility to take time off.
There are only a handful of places where I doubted his objectivity.
He reports one study showing evidence of racial discrimination in home loans, but fails to mention any of the contrary evidence such as the Anderson and Vanderhoff paper showing higher marginal default rates for blacks.
The final few pages on policy implications seem poorly thought out compared to the rest of the book (he says that’s the least important chapter of the book). He claims that income taxes on the bottom quintile can be reduced to zero by a 10% increase on the top quintile, but that claim depends on assumptions about how reported income changes in response to tax increases. He doesn’t indicate what assumptions his claim depends on.
He claims “The high rate of incarceration in the United States and the high level of inequality are related.” He gives a plausible theory about why inequality causes the wealthy in some countries to spend a lot protecting their wealth from the poor, but provides no evidence connecting that theory to U.S. incarceration rates.

Early this week, the Federal Reserve Board lowered interest rates at an unexpected time by a surprisingly large amount.
I see three possible explanations, which I think are about equally likely.

  • The Fed has evidence that the economy is slowing more than markets have realized.
  • The Fed has evidence that some big financial institutions have troubles that are endangering the careers of some influential people, and is bailing out those institutions in hopes that those people will use their influence to enhance the job security of the people in charge of the Fed.
  • Bernanke isn’t interested in the kind of publicity he can get by maximizing the total number of rate cuts. He realizes that a steady, predictable series of small rate cuts doesn’t stimulate the economy as well as cutting rates far enough that it isn’t easy to predict that more rate cuts will be needed (for one thing, making further rate cuts predictable creates incentives to postpone borrowing to when rates are lower). If that’s what’s happening, it’s not going to work as well as he would like this time, because the markets think the Fed is following the predictable rate cut strategy that gives them publicity for doing something at the time that the average person is most concerned about recession.

In related news, Singapore has a system which is designed to stabilize the economy rather than to provide politicians with opportunities to claim credit for doing something about the economy.
China is imposing widespread price controls and suffering power shortages which hinder production. If China were like the U.S., I’d say it’s trying to recreate the experience the U.S. had in the early 1970s. But the way Chinese politics work, the central government probably will allow local authorities to use a lot of discretion in enforcing the price controls, so the price controls will probably only produce shortages in a few industries that are dominated by large state-owned firms.

Politimetrics (associated with the Westminster Business School) has sponsored some additional Intrade contracts which will provide information about the impact of the presidential election on the country if they ever get enough liquidity. So far, there’s been no sign that much liquidity will exist.
One reason I (and presumably other traders) haven’t placed many orders is that the contracts deal with individual candidates. Since the value of the new contracts should fluctuate with the probability of the relevant candidate’s winning, and those fluctuations are currently much larger than any other factor affecting the prices, trading them would require any trader who doesn’t accept the market price to frequently monitor the prices of the underlying contracts. Nobody wants to do that unless the contracts already have significant volume.
Even if they had some liquidity, there’s a good deal of risk that the long-shot bias which appears to be common on Intrade would limit my confidence in the value of the information provided by those prices for all but the two or three candidates who are most likely to win in November (i.e. I’d probably believe what they said about Clinton relative to Obama, but I’d doubt they would be useful for voters in Republican primaries).
When it becomes clear who will win each party’s nomination, these problems will be reduced, and I’ll probably place a moderate number of orders on some of these contracts.
It should be possible to design a better user interface for decision markets of this nature so that users could place orders purely on the probable impact of a candidate’s election. Shock response futures come closer to doing that than contracts of the form “X wins and Y happens”, but can probably only indicate the direction of the impact.
I’ve created web pages at https://bayesianinvestor.com/amm/implied.html and https://bayesianinvestor.com/amm/implied4.html (which are currently being updated 4 times a day) which show implied prices (i.e. the price of the conditional contract as a percent of the price of the underlying candidate’s contract) that ought to represent what the markets think the probable effects would be if that candidate wins. Ideally traders could place orders expressed in terms of those implied prices, but that’s nontrivial to implement, and unlikely to happen unless someone pays Intrade a fair amount to create.
I’ve commented on Jed Christiansen’s blog about why I doubt the conditional contracts I’m subsidizing have had enough trading yet to produce valuable information. But the trends suggest there will be enough trading within a few weeks.

I have implemented subsidies to encourage trading of some conditional prediction market contracts that may provide useful information about the consequences of the 2008 presidential election, via a simple automated market maker (using an algorithm described near the end of http://hanson.gmu.edu/ifextropy.html). The subsidized market maker ought to provide incentives for traders to devote more thought to these contracts than they would if the liquidity was less predictable.
Intrade has agreed not to charge any trading or expiry fees on these contracts.
Some places to look for extensive description of the motivations behind these subsidies are here and here.

The contracts are:

Please read the detailed specifications at Intrade before trading them, as one-line descriptions are not sufficient for you to fully understand them.
For the first two of those contracts, the market maker will enter bids and asks of 38 contracts, and can lose a maximum of $5187.76 on each contract. For the other four contracts, the market maker will enter bids and asks of 115 contracts, and can lose a maximum of $7906.25 on each contract.
I will maintain a web page here devoted to these contracts.

Bernie Sanders has introduced a bill to replace patent monopoly protection for drugs with awards based in part on Quality Adjusted Life Years added by the drugs.
This would eliminate the harm due to monopoly pricing. It might also cause some research to be redirected from “me-too” drugs to more innovative drugs. But I suspect that it’s common enough for what initially looks like a “me-too” drug to end up having valuable advantages that such an effect will be minor.
It would probably be a bigger help to people in developing nations than all the government spending misleadingly labeled as foreign aid.
Because politics will ensure that the idea is implemented suboptimally, I would prefer that something similar (e.g. patent buyouts) be implemented by a more responsible institution such as the Gates Foundation. But the patent system has enough problems that even this imperfectly written bill might improve on the status quo.
One strange effect of political reality is that the rewards are apportioned according to either benefits to U.S. patients or world patients, and the bill provides an awfully vague description of which rule will apply to which drug.
The bill allocates 10% of the rewards to orphan drugs, presumably because the lives of people with those diseases are worth more than those with common diseases.
The bill claims generics cost 85% less than patented drugs, but gets that figure from comparing overall generic prices with overall patented prices. If the cost of manufacturing drugs differs for old and new drugs, that will be misleading. The estimates I’ve found for same-drug price declines after generic competition starts suggest the price decline is more like 30% to 50%. So the bill’s claim that it can be financed by the reduced Federal government drug spending appear to be fiction.
Besides, if it were self-financing that way, wouldn’t it indicate a big reduction in the rewards to drug development? I want to see a good analysis of why $80 billion a year is adequate to substitute for patent exclusivity. My crude attempts at analyzing it suggests it’s too low, but not by a large amount.

Support U.S. troops by paying attention to their views on the presidential candidates and voting accordingly.
Ron Paul has received the most donations from people identified as current and retired military personnel of any presidential candidate, followed by Obama and McCain. That suggests withdrawal from Iraq may be more popular with the military than it is with other voters. McCain’s strength might be a response to his military experience and/or his opposition to torture. (HT Andrew Sullivan).

Book review: Black Rednecks And White Liberals by Thomas Sowell.
Thomas Sowell is a pretty smart guy. It’s unfortunate that he wastes his skills on reinforcing peoples’ existing political opinions. Much of what he says in this book is right, but the new ideas it offers don’t seem like they ought to change the political opinions of anyone who has thought much about racial politics. And the old but wise arguments are written in a style that seems designed to turn off anyone who isn’t already a fan of Sowell’s ideas.
He presents interesting evidence that the culture of black ghettos came from parts of Britain that were uncivilized at the time its bearers moved to the southern U.S. This is the kind of subject where it’s virtually impossible for most readers to tell whether he’s being objective or selecting evidence to fit his biases. More importantly, it’s hard to tell why it matters. Some people pay lip service to the authenticity of black culture, but I find it hard to believe that the origins of the culture several centuries ago plays an important role in peoples’ choice to adopt the culture.
One interesting aspect of Sowell’s story is that the large migration from the rural south to the urban north after WWII did not result in the usual assimilation of the migrants into the culture of the area they moved to. How much of that was due to the number of migrants, to their culture, or to their race? Sowell ignores this subject.
Sowell’s argument that western civilization was responsible for the nearly worldwide abolition of slavery seems mostly right, but I’m disturbed by his exaggerations. He misleads readers into thinking that the first abolitionists were western, but a quick web search told me that Cyrus the Great wanted to abolish slavery worldwide two millennia earlier.
There are several places in the book where he makes confident, unsupported assertions as if they were certain, when I doubt anyone has enough evidence to make anything better than a rough guess. For instance, he thinks George Washington couldn’t have gotten a prohibition on slavery into the constitution without driving the south out of the union (plausible, but it depends on hard-to-verify assumptions about his powers of persuasion), and that slavery would have lasted longer without the union (a controversial enough claim that abolitionists such as William Lloyd Garrison seemed to reject it, claiming the north would be a better haven for runaway slaves if it seceded and repealed the Fugitive Slave Law). There are probably some leftists who unfairly attack Washington for failing to accomplish more than he could possibly accomplish, but I don’t see signs that they get respect from anyone who would listen to Sowell.
I’m quite suspicious of Sowell’s claim that Hitler’s pretenses of having been provoked into military action were intended only to fool people in Germany. Even if people in other countries had enough information to know Hitler was lying, it’s easy to imagine that a fair number of them were looking for a way to rationalize neutrality, and that Hitler was helping them to fool themselves.

Jury Incentives

The jury system in the U.S. originated in times when most communities were small enough that jurors were likely to feel close enough to defendants to have tribal/friendship/etc desires not to convict someone without cause, and to be sufficiently at risk from a defendant’s future crimes to take some care not to acquit the guilty. But today, those motives have broken down in many urban and suburban places, and trials are often decided by those who are too dumb to get off jury duty.
I don’t have good ideas for ensuring that jurors are chosen so that they feel like they’re part of the same small community as the defendant, so I’m hoping instead to create new incentives for jurors to care about verdicts.
Simply increasing the pay for serving on a jury would help to avoid the problem of jurors being selected for low intelligence, but I can’t tell how much of the problem that would solve.
I propose a additional ways of rewarding jurors based on results. If the jurors acquit, the jurors could get some large payment in 5 or 10 years if the defendant commits no crimes during that time, but no further payment if the defendant commits a crime. If the jurors convict, the jurors could get some large payment in 5 or 10 years unless the defendant has been exonerated or the conviction reversed on appeal.
The size of the payments would need to be carefully calibrated so that the average award is the same for juries that convict as it is for those that acquit.
Since it would take forever for the government to work out all the details needed to translate these ideas into a fair and predictable system, I’m wondering whether a private charity could implement them. Presumably there are significant legal obstacles to many kinds of payments to jurors, since it’s easy for such payments to be intended to serve the interests of one party to the trial. I can’t tell whether the relevant laws are broad enough to prohibit desirable incentives, or if so whether it’s feasible to relax those restrictions.
