"Social" science

A novel kind of crowd-sourcing is described in: In a Video Game, Tackling the Complexities of Protein Folding

"Proteins are essentially biological nanomachines that carry out myriad functions in the body, and biologists have long sought to understand how the long chains of amino acids that make up each protein fold into their specific configurations.

"In May 2008, researchers at the University of Washington made a protein-folding video game called Foldit freely available via the Internet. The game, which was competitive and offered the puzzle-solving qualities of a game like Rubik’s Cube, quickly attracted a dedicated following of thousands of players.

"The success of the Foldit players, the researchers report in the current issue of Nature, shows that nonscientists can collaborate to develop new strategies and algorithms that are distinct from traditional software solutions to the challenge of protein folding.

"The researchers took pains to credit the volunteers who competed at Foldit in the last two years, listing “Foldit players” at the end of the report’s author list and noting that more than 57,000 players “contributed extensively through their feedback and gameplay.” "

The (changing) market for law professors

The New Realities of the Legal Academy by Lawrence B. Solum

 "Abstract: This short paper is the Foreword to Brannon P. Denning, Marcia L. McCormick, and Jeffrey M. Lipshaw, Becoming a Law Professor: A Candidate's Guide, American Bar Association, Forthcoming.

"One of the great virtues of Denning, McCormick and Lipshaw’s guide is that it reflects the changing nature and new realities of the legal academy. Not so many years ago, entry into the elite legal academy was mostly a function of two things - credentials and connections. The ideal candidate graduated near the top of the class at a top-five law school, held an important editorial position on law review, clerked for a Supreme Court Justice, and practiced for a few years at an elite firm or government agency in New York or Washington. Credentials like these almost guaranteed a job at a very respectable law school, but the very best jobs went to those with connections - the few who were held in high esteem by the elite network of very successful legal academics and their friends in the bar and on the bench. The not-so-elite legal academy operated by a similar set of rules. Regional law schools were populated by a mix of graduates from elite schools and the top graduates of local schools, clerks of respected local judges, and alumni of elite law firms in the neighborhood. In what we now call the "bad old days," it was very difficult indeed for someone to become a law professor without glowing credentials and the right connections.

"But times have changed. When the Association of American Law School’s created the annual Faculty Recruitment Conference (or FRC) and the associated Faculty Appointments Register (or FAR), the landscape of the legal academy was forever changed. The change was slow in coming. For many years, candidates were selected for interviews at the FRC on the basis of the same old credentials and connections, but at some point (many would say the early 1980s), the rules of the game began to change. In baseball, a similar change is associated with Billy Beane, the manager of the Oakland Athletics, who defied conventional wisdom and built winning teams despite severe financial constraints by relying on statistically reliable predictors of success. The corresponding insight in the legal academy (developed by hiring committees at several law schools) was that the best predictor of success as a legal scholar was a record of publication. It turns out that law school grades, law review offices, and clerkships are at best very rough indicators of scholarly success. But those who successfully publish high quality legal scholarship are likely to continue to do so."
The paper itself is only 3 pages, and the abstract is a good summary...

Matching services for friends?

Robin Hanson asks "Why Not Friend Match?" I.e. why are there dating sites but not friend sites?

That isn't to say that there aren't friend matching sites (e.g. here, and here, not to mention  Facebook), but nevertheless his conjecture strikes me as plausible: we (at least initially) draw our friends from the people and places we encounter for other reasons, since friends complement our other activities. Or, as he puts it:

"Since we need friends in substantial part to serve as allies in our social world, supporting us against opposing coalitions, it makes sense to draw our friends from our existing social world. And since we need mates more for their personal quality, e.g., good genes, youth, wealth, smarts, mood, etc., it makes sense to pick them more via such features."

The international market for ironing boards

The Washington Post reports Indiana ironing-board factory faces stiff competition from Chinese companies.
"There is one factory left in the United States that manufactures the basic ironing board, and its survival against Chinese competition demands unrelenting, production-line hustle.
"The 200 people at the plant in this small town make their boards very, very cheaply and as fast as 720 in an hour. In three low-slung buildings without air conditioning, coils of cold-rolled steel are cut, welded, riveted and boxed, then loaded onto the Wal-Mart and Target trucks backed up to the loading dock. Paid with piece-rate incentives, workers emerge weary at shift's end.

"The people on the line are making pretty good money; it can work out to about $15 an hour," said Dave Waskom, 61, a tool and die maker who readied the plant's machinery for 37 years. "But they work like dogs."

"Yet loyalty and hard work are not enough.

The company survives in part because it convinced U.S. trade officials that Chinese firms were unfairly dumping ironing boards into the United States at less than fair-market value; in response, the United States levied anti-dumping taxes of 70 to more than 150 percent on its Chinese rivals."

Another live liver donation tragedy

Live liver donation remains much more dangerous than kidney donation: Donor dies after live liver transplant at CU Hospital


AURORA, Colo. - A man who agreed to donate part of his liver to help save his brother died just four days after the transplant procedure at The University of Colorado Hospital.


"It's the first death of a living liver donor in Colorado and only the fourth in the U.S.

"The death has led to a temporary halt of all live donor liver transplants at The University of Colorado Hospital. The hospital has also launched an investigation into what went wrong.

"It has reported the death to the Colorado Department of Public Health, which is conducting its own investigation.

"Ryan Arnold, 34, of Watertown, South Dakota died on August 2nd, just four days after his brother, Chad, 38, of Castle Rock, received part of his liver. "

There was an earlier death this year.

Suicide and organ donation

Assisted suicide is one of the persistently repugnant transactions, although it is the subject of a good deal of modern debate around the world. Here's a story likely to give you pause to think: Lou Gehrig's victim: Kill me for my organs 

"he ... compares his situation to a soldier in a foxhole throwing himself on a grenade to save his comrades.

"I am not suicidal," he says. "I just know that it is a matter of time before I die and wish to do a good thing for those people who have a good life expectancy"

The market for celebrity endorsements

The story under this eye-catching headline sheds some light on the endorsement biz: Paris Hilton Sued for $35M for Wearing Wrong Hair

"A company that manufactures hair extensions claimed the 29-year-old socialite breached her contract to wear and promote their product when she sported the fake locks of a competitor in 2008.
Hairtech International Inc. is seeking $35 million in damages -- 10 times what she was apparently paid under the contract. The fraud and breach-of-contract suit cites the heiress' partying as contrary to Hairtech's marketing campaign.
The filing also claims Hilton missed a launch party for the hair extension line because she was serving a stint in jail in 2007. Hilton served 23 days in 2007 after she was caught driving twice on a suspended license while on probation for reckless driving.
The filing states the company's lost $6.6 million on the launch party alone, although a jury or judge will have to decide whether Hilton owes any money if the case goes to trial."

Language exchanges

Learning a Language From an Expert, on the Web reports on various communities of language learners who help each other out.
"Livemocha, a Seattle company with $14 million in venture capital financing, mixes a social network with lessons for more than 38 of the world’s more common languages.

"The initial lessons are free, but unlocking some of the additional features requires a fee to Livemocha (starting at $10 for a set of lessons) or an agreement to correct the work of others..."

"MyLanguageExchange.com just maintains lists of people who know certain languages and want to learn others. Anyone can search the database, but only gold members, who pay $24 a year, can send e-mail easily to others."
...
"RhinoSpike.com set up a market for recordings spoken by native speakers. Anyone can post a selection of text and anyone can post a recording."
...
"Companies like RosettaStone.com, GermanPod101.com, ChinesePod.com and a surprisingly large number of other Web sites are competing to offer lessons and tutoring to students throughout the world. I found dozens of others offering what was found only on PC software a few years ago.

...
"There are even more casual approaches that come with even less infrastructure and fewer of the protections for consumers that it may offer. It is easy to find, for instance, people who want to practice languages with a free phone call through the forums run by Skype. One click and you can talk free with someone who wants to practice another language. The standard protocol is to spend half the time on one language and half the time with the other.

"Some sites, like UsingEnglish.com, englishcafe.com and Englishbaby.com, are devoted to helping people practice English but add the elements of sharing photos and interests like a dating service. "

Education as a filter--for Supreme Court justices

Yale, Harvard Law Taking Over Supreme Court
"In a new paper, Patrick J. Glen, an adjunct professor at Georgetown University Law Center, researched the legal educations of Supreme Court justices through time and found a curious pattern."
...
"However you categorize Justice Ginsburg’s pedigree, one fact would still be guaranteed by Ms. Kagan’s confirmation: For the first time in history, every sitting Supreme Court justice will have graduated from an Ivy League law school.



Mr. Glen writes, “Kagan will take the place not only of the last remaining Protestant on the Court, but also of its last non-Ivy League hold-out—the Chicago educated Justice John Paul Stevens (Northwestern Law School).”
So in some respects, the court has gotten a little more diverse over the years, with Congress confirming more racial minorities and women. But perhaps that just reflects the changing admissions processes at the nation’s top two law schools."

In this story covering her swearing in, the Times' Peter Baker writes
"Arguably, Justice Kagan made a mark from the moment she took the oaths on Saturday. She is the third woman on the current court, joining Justices Ruth Bader Ginsburg and Sonia Sotomayor. She is also the fifth justice born after World War II, making that group a majority, and she brings down the average age on the court to 64, from nearly 69. And she is the first person since William H. Rehnquist, 38 years ago, to join the court without experience as a judge.
If her installation added diversity in some ways, though, it reinforced the court’s lack of it in other areas. Her addition means the court now includes neither Protestants nor anyone without an Ivy League background. Justice Kagan joins two other Jewish justices and six Catholics. She is the sixth justice to have studied at Harvard Law School (although Justice Ginsburg later transferred to and graduated from Columbia Law School); the other three graduated from Yale Law School. And she is the fourth justice to have grown up in New York City."

Marriage, jobs, and immigration

A recent NBER paper relates two things whose interaction has fascinated me for some time (the marriage and job markets) with a third, immigration.

America's settling down: How Better Jobs and Falling Immigration led to a Rise in Marriage, 1880 – 1930 by Tomas Cvrcek, NBER Working Paper No. 16161, July 2010.

Abstract: The growing education and employment of women are usually cited as crucial forces behind the decline of marriage since 1960. However, both trends were already present between 1900 and 1960, during which time marriage became increasingly widespread. This early period differed from the post-1960 decades due to two factors primarily affecting men, one economic and one demographic. First, men’s improving labor market prospects made them more attractive as marriage partners to women. Second, immigration had a dynamic effect on partner search costs. Its short-run effect was to fragment the marriage market, making it harder to find a partner of one’s preferred ethnic and cultural background. The high search costs led to less marriage and later marriage in the 1890s and 1900s. As immigration declined, the long-run effect was for immigrants and their descendants to gradually integrate with American society. This reduced search costs and increased the marriage rate. The immigration primarily affected the whites’ marriage market which is why the changes in marital behavior are much more pronounced among this group than among blacks."

Brokers for pirate ransom

Suppose your ship were hijacked by Somali pirates, and you wanted to ransom it and the crew. How would you go about it?  You would need a middleman, someone who could get the money to the right pirates, and maybe who played a repeated game with them, to help ensure that the release would go as planned. As it happens, you might become the client of a certain kind of British law firm, whose market is now threatened by the imposition of sanctions against those who deal with certain named Somali pirates. The problem is, it may be impossible to pay a ransom without doing business with the embargoed individuals. The Financial Times reports: Somali crackdown threatens City role on ransoms

"International plans for a legal crackdown on the funding of piracy could scupper a burgeoning City industry.
"The United Nations plans for sanctions on two suspected pirates would hit the often lucrative work of the law firms, insurers and private security companies in London that quietly arrange ransoms to free kidnapped ships and crews."
...
"The government has decided to block the UN plans amid worries they could force shipowners and their advisers to stop paying ransoms or else risk prosecution.


"London’s piracy negotiation business brings together an unusual cast of characters, from hard-bitten security operatives to dapper lawyers making telephone calls to hijacked ships from offices close to the banks of the Thames.


"NYA International, a kidnap response specialist based off Bishopsgate and now part of Aon, the US insurance broker, has advised on more than 20 piracy incidents during the past 18 months or so.


"The leading ship hijack case law firm in terms of numbers of clients is said to be Holman Fenwick Willan, which has offices north-west of the Tower of London.


"James Gosling, partner at HFW, said: “Nobody wants to pay ransoms. But when it’s the only option, what the hell else do you do?” "
...
"The concern about sanctions is that, while they do not explicitly outlaw the payment of ransoms, they make it impossible in practice because of the uncertainty about where money given to pirates will end up.
“The problem is the due diligence,” Mr Roberts said. “How can you possibly know if the money is going to that [sanctioned] person or not?”
"Maritime lawyers in London say they were encouraged by a High Court ruling this year that paying ransoms wasn’t contrary to British public policy, although they admit the argument over the subject is increasingly becoming political rather than legal.
"That is why the capital’s community of piracy-related businesses is appealing to the government to hold firm in stopping the UN proposal and the sanctions it would introduce.
"As one London-based insurer, who asked not to be named, put it: “We would be very concerned if shipowners were denied a means to free pirated ships.
“There are no navies prepared to go all guns blazing to rescue people – and it wouldn’t work, either.” "

New Orleans Receivables Exchange

In several earlier posts I've been following the progress of the New Orleans Receivables Exchange.

The State of Louisiana has now passed some legislation that makes it easier for companies to sell their accounts receivable: here's the text of the Louisiana Exchange Sale of Receivables Act.

And here's an article from Inc. Magazine: A New Liquidity Solution

Korean marriage brokers for foreign brides

After a tragedy involving the death of a young woman, SKorea Cracks Down on Marriage Brokers .

"...Her death in early July has drawn attention to the growing trend of South Korean men looking overseas for brides...
"Over the past decade, a growing number of South Korean men, particularly from farming villages with dwindling populations, have been looking overseas for wives....
"They pay an average of $9,900 to brokers to connect them with young women looking for economic security, mostly from Southeast Asia and China, Heo said.

''International marriages are in a way a practical intersection of interests, bringing together South Korean bachelors and foreign women who suffer from poverty and have a romanticized notion of a prosperous life in an industrialized country like South Korea,'' Heo said.
"In 2009, 180,000 foreigners were married to South Koreans, including more than 35,000 Vietnamese women, the Ministry of Public Administration and Security said.
"Many met their spouses through the estimated 1,250 marriage brokers or matchmakers who arrange an estimated 15,000 marriages each year between South Korean men and foreign women, mostly from Southeast Asia, the Ministry of Gender Equality and Family said. "

Organ donation registration on income tax forms


"LANSING, Mich. - Michigan's secretary of state wants to make organ donation easier by adding a checkoff box on annual tax forms.
Terri Lynn Land says the box would be similar to the current section of the tax form that asks filers if they want part of their taxes to go to the State Campaign Fund.
Tax filers would have the option of marking the box which allows their names to be added to Michigan's Organ Donor Registry.
Land says the proposal allows for a convenient way for organ donors to sign up and allows every Michigan taxpayer to be reached "at virtually no cost" during current lean fiscal times. Her proposal has to go before the state Legislature."

The market for electricity

As the supply of electricity changes in response to growing numbers of wind turbines, there's more need to be able to store electricity: Wind Drives Growing Use of Batteries

"In New York and California, companies are exploring electrical storage that is big enough to allow for “arbitrage,” or buying power at a low price, such as in the middle of the night, and selling it hours later at a higher price. In the Midwest, a utility is demonstrating storage technology that can go from charge to discharge and back several times a minute, or even within a second, bracing the grid against the vicissitudes of wind and sun and transmission failure. And in Texas, companies are looking at ways of stabilizing voltage through battery storage in places served by just one transmission line."

I also recently heard of attempts to create more flexible demand by fitting households with electrical heat storage units, that heat bricks when electricity is cheap, and power the household heating system off the stored heat.

School choice in Darebin City, Victoria, Australia

It sounds like at least one school district in Australia has less bureaucracy than my colleagues and I have encountered in helping American cities reorganize their school assignment systems. Kwanghui Lim at CoRE Economics reports: Game Theory in Action: Sven Feldmann on Kindergarten Matching.

More on school choice here, and here. (And here is a video of Muriel Niederle presenting a new school choice algorithm to the San Francisco school board meeting that gave the go ahead for a redesign there.)

WHO: blood donation insufficient in developing countries

The World Health Organization reports
  • "65% of all blood donations are made in developed countries, home to just 25% of the world's population.
  • In 73 countries, donation rates are still less than 1% of the population (the minimum needed to meet basic needs in a country). Of these, 71 are either developing or transitional countries.
  • 42 countries collected less than 25% of their blood supplies from voluntary unpaid blood donors, which is the safest source.
  • 31 countries still reported collecting paid donations in 2007, more than 1 million donations in total.
  • 41 countries were not able to screen all blood donations for one or more of the following transfusion-transmissible infections (TTIs)–HIV, hepatitis B, hepatitis C and syphilis."
They recommend programs of voluntary blood donation:
"Safe blood donors are the cornerstone of a safe and adequate supply of blood and blood products. The safest blood donors are voluntary, non-remunerated blood donors from low-risk populations. Despite this, family/replacement and paid donors, which are associated with a significantly higher prevalence of transfusion-transmissible infections (TTIs) including HIV, hepatitis B, hepatitis C, syphilis and Chagas disease, still provide more than 50% of the blood collected in developing countries. WHO advocates and recommends to its Member States to develop national blood transfusion services based on voluntary non-remunerated regular blood donation in accordance with World Health Assembly resolution 28.72, which was adopted in 1975. "

Kidney Exchange in South Korea

S. Korea was a pioneer in kidney exchange. (In the U.S. population, Asians have the highest frequency of blood type B, almost equal to their frequency of A, and so the simplest exchanges of an A-B patient donor pair with a B-A patient donor pair come up more often among Asians.)
Here's a report of their experience.
J Korean Med Assoc. 2008 Aug;51(8):717-723. Korean.
Exchange Living-donor Kidney Transplantation: The Present and Future. Huh KH, Kim YS, Kim BS. Department of Surgery, Yonsei University College of Medicine, Korea. yukim@yuhs.ac Department of Internal Medicine, Yonsei University College of Medicine, Korea. Abstract The shortage of donor organs is one of the major barriers of transplantation worldwide. After the success of the direct exchange donor (swap) program in Korea since 1991, a swaparound program has been developed. Recently, a web-based (computerized) algorithm to facilitate donor kidney exchange was devised and tested in multi-center settings. An excellent longterm outcome was achieved by using the donor exchange program as an option to reduce the donor organ shortage. Herein, we discussed on the current status of the exchange donor renal transplantation in Korea, a couple of problems we have had, and future directions we have to head and make better to improve organ donation activities.

More market design in Hebrew

Forbes has an Israeli edition, and here is a Hebrew translation of the article that ran in English here.

(Here's a different market design article in Hebrew, featuring Itai Ashlagi, that I posted about earlier.)

Repugnance and/or disgust

I like to distinguish what I've called repugnant transactions from those that elicit disgust. By repugnant transactions I mean transactions that some people want to engage in and that others don't want them to (e.g. same sex marriage, or buying or selling a kidney, or ordering horse meat at a U.S. restaurant). One sign that a transaction is viewed as repugnant by a sufficiently big part of the population is if it is illegal. Disgusting transactions most often don't elicit legislation (except in a consumer protection way), e.g. it's illegal in CA to offer to sell horse meat for human consumption, but not, say, spit: the difference being that some people would like to buy and eat horse meat.

However there's no denying that part of what makes some transactions repugnant to some people is that they find them disgusting (see e.g. Martha Nussbaum on same sex marriage). There have been recent reports in the press and blogosphere on attempts to link physiological indicators of disgust to, among other things, political proclivities.

Nicholas Kristof in the NY Times gives a quick overview of some conclusions of this sort: Our Politics May Be All in Our Head

Mark Liberman at Language Log takes a closer look: Physiological politics, and suggests that at least some of the results could be artifacts of the experiment. (He has a followup here: Icktheology.)

In the context of organ transplantation, I've noted that the repugnance to sales of organs is hard to equate with a visceral disgust reaction, since there isn't repugnance to transplants in general. There may of course be specific exceptions to that, see e.g. this article in the American Journal of Transplantation:

"Specific Unwillingness to Donate Eyes: The Impact of Disfigurement, Knowledge and Procurement on Corneal Donation" (p 657-663)M. Lawlor, I. Kerridge, R. Ankeny, T. A. Dobbins, F. BillsonPublished Online: Jan 29 2010 2:23PM
