The NY Times has an article on those who wish to have their remains frozen after death, in the hope of eventual resurrection at a time when medical technology might make that feasible. Much of the story focuses on economist Robin Hanson of GMU, and his wife Peggy Jackson, a hospice worker who finds the idea unpleasant. The article goes on to say that this is quite common: many people, in particular the spouses of enthusiasts, find the idea repugnant. (It's not every NY Times article about an economist that includes references to Gilgamesh and Voldemort...)
Until Cryonics Do Us Part
"Robin, a deep thinker most at home in thought experiments, says he believes that there is some small chance his brain will be resurrected, that its time in cryopreservation will be merely a brief pause in the course of his life. Peggy finds the quest an act of cosmic selfishness. And within a particular American subculture, the pair are practically a cliché.
"Among cryonicists, Peggy’s reaction might be referred to as an instance of the “hostile-wife phenomenon,” as discussed in a 2008 paper by Aschwin de Wolf, Chana de Wolf and Mike Federowicz.“From its inception in 1964,” they write, “cryonics has been known to frequently produce intense hostility from spouses who are not cryonicists.” The opposition of romantic partners, Aschwin told me last year, is something that “everyone” involved in cryonics knows about but that he and Chana, his wife, find difficult to understand. To someone who believes that low-temperature preservation offers a legitimate chance at extending life, obstructionism can seem as willfully cruel as withholding medical treatment. Even if you don’t want to join your husband in storage, ask believers, what is to be lost by respecting a man’s wishes with regard to the treatment of his own remains? Would-be cryonicists forced to give it all up, the de Wolfs and Federowicz write, “face certain death.”
"Premonitions of this problem can be found in the deepest reaches of cryonicist history, starting with the prime mover. Robert Ettinger is the father of cryonics, his 1964 book, “The Prospect of Immortality,” its founding text. “This is not a hobby or conversation piece,” he wrote in 1968, adding, “it is the struggle for survival. Drive a used car if the cost of a new one interferes. Divorce your wife if she will not cooperate.” Today, with just fewer than200 patients preserved within the two major cryonics facilities, the Michigan-based Cryonics Institute and the Arizona-based Alcor, and with 10 times as many signed up to be stored upon their legal deaths, cryonicists have created support networks with which to tackle marital strife. Cryonet, a mailing list on “cryonics-related issues,” takes as one of its issues the opposition of wives. (The ratio of men to women among living cyronicists is roughly three to one.) “She thinks the whole idea is sick, twisted and generally spooky,” wrote one man newly acquainted with the hostile-wife phenomenon. “She is more intelligent than me, insatiably curious and lovingly devoted to me and our 2-year-old daughter. So why is this happening?” "
...
"Whether or not the human race subconsciously equates attempts to defeat death with treachery, it’s true that a general air of menace hangs over the quest for immortality in Western literature. Think Gilgamesh or Voldemort. “There is a lot of ancient cultural stereotyping about the motives and moral character of people who pursue life extension,” says James Hughes, the executive director of the Institute for Ethics and Emerging Technologies, a nonprofit organization enamored of life extension. Hughes has chosen not to participate in what he considers a worthy experiment. “Although it’s a rather marginal bet for a potentially huge payoff,” he says, “I value my relationship with my wife.” "

The Market for scientists
"It’s not an education story, it’s a labor market story,” says Harold Salzman in a Miller-McCune story by Beryl Lieff Benderly about the market for scientists:The Real Science Gap
"It’s not insufficient schooling or a shortage of scientists. It’s a lack of job opportunities. Americans need the reasonable hope that spending their youth preparing to do science will provide a satisfactory career."...
"Many young Americans bright enough to do the math therefore conclude that instead of gambling 12 years on the small chance of becoming an assistant professor, they can invest that time in becoming a neurosurgeon, or a quarter of it in becoming a lawyer or a sixth in earning an MBA. And many who do earn doctorates in math-based subjects opt to use their skills devising mathematical models on Wall Street, rather than solving scientific puzzles in university labs, hoping a professorship opens up."

Growth of kidney donation by unrelated donors
Kidney exchange has allowed more people to receive kidneys from unrelated donors, but that isn't all that's going on, it has also become more acceptable for people to receive a kidney from friends and even people who they met on the internet.
George Taniwaki--a prospective donor who publishes a very interesting blog--has a post on this, The rise of unrelated donor transplants.
It includes admirably clear data graphics and analysis.
"Even more interesting is the extremely rapid rise of alternative sources of living donors. The last three lines from the figure above are rescaled in the figure below. The fastest growing source of living donors is paired exchanges. ... Kidney exchanges have the potential of becoming the leading source of live donor kidneys within a few years."
In addition, he has some insights into some of the complicated politics of kidney transplantation, in which there is some over-claiming of "firsts."
"The final fast-growing source of donors are people who donate without a specific recipient in mind. They are called nondirected or altruistic donors. Johns Hopkins Medicine claims to have performed the first nondirected live donor transplant in September, 1999. However, UNOS data shows two earlier donors in 1998 and one in 1988, the first year data is available. In addition to increasing the total number of donations, nondirected donors also play an important role in starting donor chains in kidney exchanges. Donor chains reduce the risk to recipients of their matched donors backing out an exchange after the first transplant takes place. Thus, nondirected donors reduce the need to perform the transplant surgeries simultaneously. This simplifies scheduling personnel and operating rooms for kidney exchange transplants."

Grade inflation in law schools
The NY Times report that some law schools are retroactively raising the grades they have given to their students, in an effort to improve their prospects in the difficult market for many law grads: In Law Schools, Grades Go Up, Just Like That.
"[Loyola Law School in Los Angeles] is retroactively inflating its grades, tacking on 0.333 to every grade recorded in the last few years. The goal is to make its students look more attractive in a competitive job market.
In the last two years, at least 10 law schools have deliberately changed their grading systems to make them more lenient. These include law schools like New York University and Georgetown, as well as Golden Gate University and Tulane University, which just announced the change this month. Some recruiters at law firms keep track of these changes and consider them when interviewing, and some do not.
Law schools seem to view higher grades as one way to rescue their students from the tough economic climate — and perhaps more to the point, to protect their own reputations and rankings. Once able to practically guarantee gainful employment to thousands of students every year, the schools are now fielding complaints from more and more unemployed graduates, frequently drowning in student debt.
They have come up with a number of strategic responses. Besides the usual career counseling measures, many top schools have bumped up their on-campus interview weeks from the autumn to August, before the school year even starts, because they want their students to have a chance to nab a job slot before their counterparts at other schools do. "
...
"Harvard and Stanford, two of the top-ranked law schools, recently eliminated traditional grading altogether. Like Yale and the University of California, Berkeley, they now use a modified pass/fail system, reducing the pressure that law schools are notorious for. This new grading system also makes it harder for employers to distinguish the wheat from the chaff, which means more students can get a shot at a competitive interview. "
For a paper on grade inflation and job markets, see
Michael Ostrovsky and Michael Schwarz, 2010, "Information Disclosure and Unraveling in Matching Markets." American Economic Journal: Microeconomics, 2(2): 34–63.
It's behind a subscription wall, but here's the abstract:
"This paper explores information disclosure in matching markets. A school may suppress some information about students in order to improve their average job placement. We consider a setting with many schools, students, and jobs, and show that if early contracting is impossible, the same, "balanced" amount of information is disclosed in essentially all equilibria. When early contracting is allowed and information arrives gradually, if schools disclose the balanced amount of information, students and employers will not find it profitable to contract early. If they disclose more, some students and employers will prefer to sign contracts before all information is revealed."

Future organ replacement
I expect that your grandchildren will have the luxury of viewing all the work on kidney exchange and transplantation generally as primitive medicine ("Grandpa, they used to take an organ from one person and sew it into another??").
At the XXIII International Congress of the Transplant Society next month there will be some discussion of Stem Cells and Regeneration, along with more prosaic, current clinical issues.
A small step towards that future is reported in Science: Rats Breathe With Lab-Grown Lungs
and in the Boston Globe: N.E. researchers create functioning lung tissue--A vital step in the quest to build organs.
From the Globe: "Two teams of researchers from New England have built living, breathing lung tissue in the laboratory — feats of engineering that could speed up the development of new drugs and bring researchers a step closer to the tantalizing dream of growing replacement lungs for patients."
In the meantime, I'm cheered by the progress we're making in primitive medicine, back in these days at the dawn of the 21st century (see here and, more generally, here, or my post last summer at which a prize was awarded to Mike Rees for some of that progress).

Ribald 4th of July: memories of July 1970
The title of this post comes from a typo in an article about the 4th of July celebrations that have been conducted since 1912 at Rebild National Park in Denmark, after the land for the park was donated by Danish-Americans. Here's the story that gets the name right:
"Every July 4 since 1912, except for the two world wars, large crowds have gathered in the heather-covered hills of Rebild in Jutland, Denmark to celebrate US Independence Day.
The site of the celebration is the beautiful Rebild National Park (20 kilometers south of Aalborg), presented to the Danish nation by Danish-Americans in 1912. "
This reminds me that in July of 1970 I was in Fredericia Denmark, briefly employed by the J.P. Schmidt cigarfabrik (sold in 1982 to the Scandinavian Tobacco Group). I wasn't rolling cigars, but programming computers, or rather a computer, an IBM 360 model 20, that used a language called Report Program Generator (RPG) that apparently has descendents still in use today. (To compile, a giant stack of punchcards had to be turned upside down to be placed on the card reader...I know that some of you don't know what punchcards were...)
On July 1, 1970, the second Vietnam War draft lottery was conducted back in the United States, to determine the draft order of men born in my year. This was long before the internet, and so I waited a day for the International Herald Tribune to report on the story, but they only reported the first number chosen, and the last. I called the American consulate in Copenhagen to try to find out my lottery number, but they didn't have the whole list either (I got the impression they thought that most Americans living in Denmark at the time may have already decided not to respond to the draft...). I had to wait for a letter from my parents to arrive, telling me that I had a number that might have made me an infantryman had I been a year older, but that with the war winding down left me free to remain a student.
Two days after July 4 I heard cannon (or maybe fireworks) on the old town wall, and came in to work to hear that this was an annual celebration of the Danish victory in The Battle of Fredericia 6th of July 1849, in which the Danes had beaten back a German siege of the fortified town. I recall my colleagues told me that it had been celebrated each year since, "except when we are occupied by the Germans."
Let's all celebrate independence with a boisterous (if not ribald) 4th of July.

The market for fireworks, July 4th 2010
“Happy Fourth of July—made in China.”
"“there are virtually no fireworks being manufactured in the U.S.,” says John Rogers, who travels to China three to four times a year with the American Fireworks Standards Laboratory, a Bethesda, Md.–based nonprofit focused on consumer safety. Rogers says 90 percent of the world’s fireworks originate in China"
...
"As for the other 10 percent, James Widmann, president of Connecticut Pyrotechnic Manufacturing, says some originate in India, Spain and other parts of Europe. Mexico, he says, could eventually become a major supplier to the U.S. because of its ability to send fireworks here by truck rather than shipping them overseas—a process fraught with obstacles. “Most shipping companies don’t want to risk sacrificing 99 percent of their cargo” for the sake of the “1 percent that can blow it all up”

Sidney Siegel and Psychology & Economics
That's the subject of a recent article: Innocenti, Alessandro, "How a psychologist informed economics: The case of Sidney Siegel," JOURNAL OF ECONOMIC PSYCHOLOGY,31, 3, 421-434, JUN 2010
"Abstract: In the 1950s before Kahneman and Tversky showed how behavioral economics could bring economics and psychology into a unified framework, a social psychologist, Sidney Siegel, entered the realm of economics and laid the foundation of experimental economics. This paper gives an assessment of Siegel's effort to meld psychology and economics and shows that Siegel was not only a contributor to the methodology of experimental economics but also a pioneer of behavioral economics. Although his legacy was paramount in the work of the Nobel Prize winner Vernon Smith, Siegel endorsed a very different approach to making interdisciplinary research effective. "

Advertising versus data on dating web sites
Advertising is easier to come by than data: apparently no one really knows much about the effect of online dating sites on producing marriages and relationships. A recent story in the Washington Post points this out (while suggesting the numbers may have peaked):Are dating Web sites past their prime?
And here is an older WSJ story:Marriage-Maker Claims Are Tied in Knots--Online Dating Sites Say Hordes of People Ultimately Marry, but Their Methods Have Plenty of Hitches of Their Own,along with an online post pointing out that there may be special selection problems facing online surveys of online activity: How Many Marriages Started Online?

School choice in Spain
Flip Klijn writes:
"Hey Al,
Recently, a letter in the Spanish newspaper "La Vanguardia" questions the new mechanism to assign students to universities in Spain.
Link to the letter in Catalan:http://www.lavanguardia.es/lv24h/20100623/53951521785.html
The writer of the letter (a high school student) wonders whether the introduction of *multiple* access grades (the novelty) is desirable. He discusses a hypothetical scenario in which multiples access grades may in fact lead to an undesirable assignment.
I was happily surprised with his analysis. Basically, he implicitly describes the deferred acceptance mechanism through a simple but very nice example that has a priority structure with a cycle (as in Ergin, Econometrica 2002). Then, he makes the point that the assignment is fair (or stable) but not very desirable (since it is inefficient).
It was impossible for me to not react to the letter. My response (in Spanish) was published in the Blog section of the same newspaper:http://www.lavanguardia.es/lv24h/20100624/53951867284.html
In my response, I first mention that with a single access grade there is indeed no incompatibility between stability and efficiency. Next, I argue that in certain situations it might be convenient, however, to have multiple access grades in which case the deferred accepted mechanism is a natural candidate mechanism (referring to the original work of Gale and Shapley, 1962, and the application in the National Resident Matching Program). I also point out that the incompatibility between stability and efficiency in the situation with multiple access grades cannot be solved by using some other mechanism. Finally, I mention that the deferred acceptance mechanism is "hassle-free" (i.e., strategy-proof) and that the experience in Boston and New York (high schools) has been very positive. Therefore, there are reasons to believe that the deferred acceptance mechanism with multiple access grades will work satisfactorily in the assignment of students to Spanish universities."

Heads of government for and against same-sex marriage
Two of yesterday's news stories from very different parts of the world caught my eye.
Icelandic Leader in Milestone Gay Marriage
"Iceland's prime minister made history last week when she wed her longtime girlfriend, becoming the world's first head of government to enter a gay marriage. But fellow Nordic nations hardly noticed when 67-year-old Johanna Sigurdardottir tied the knot with her longtime partner -- a milestone that would still, despite advances in gay rights, be all but inconceivable elsewhere. Scandinavia has had a long tradition of tolerance for alternative lifestyles -- and cross-dressing lawmakers and homosexual bishops have become part of the landscape. ''There is some kind of passion for social justice here,'' respected cross-dressing Swedish lawmaker Fredrick Federley said. ''That everybody should be treated the same.'' "
While in Australia, this from the new prime minister:
Gillard against gay marriage
"Prime Minister Julia Gillard says she does not support legalising gay marriage in Australia.Labor policy on gay marriage will remain the same under her prime ministership, Ms Gillard told Austereo show today."We believe the marriage act is appropriate in its current form, that is recognising that marriage is between a man and a woman, but we have as a government taken steps to equalise treatment for gay couples," Ms Gillard said."

The market for kidneys in Iran
The Iranian economist Farshad Fatemi at the Sharif University of Technology sent me this link to his very interesting working paper The Regulated Market for Kidneys in Iran.
Among other things, it is full of institutional detail and comparisons. Here are a few things that caught my eye.
Comparing total (live plus deceased) kidney donation across countries, per million population, the most recent figures (from 2007) are Iran 27.1%; UK 33.5%; Spain 49.5%; US 54.7%. (His source is the Barcelona-based Transplant Procurement Management Organization, whose international database I have yet to fully explore.)
His description of the market for kidneys in Iran includes the following
"After the donor passes the initial tests, the administrators contact the first patient in the same waiting list as the donor’s blood type [and other components of a match]...
If the patient who is on the top of the waiting list at the moment is not ready for the transplant ..., the next patient will be called... until a ready patient will be found. Then a meeting between the two parties is arranged (they are provided with a private area within the foundation building if they want to reach a private agreement) and they will be sent for tissue tests. If the tissue test gives the favourable result, a contract between the patient and the donor will be signed and they will be provided with a list of the transplant centres and doctors who perform surgery.
When the patient and the donor are referred to transplant centre, a cheque from the patient will be kept at the centre to be paid to the donor after the transplant takes place. The guide price has been 25m Rials (≈ $2660) until March 2007 for 3 years and at this time18 it has been raised to 30m Rials (≈ $3190). This decision has been made because the foundation was worried of a decreasing trend in number of donors.
"In some cases, the recipient will agree to make an additional payment to the donor outside the system; it is not certain how common this practice is, but according to the foundation staff the amount of this payment is not usually big and is thought to be about 5m to 10m Rials (≈ $530 to $1060). The recipient also pays for the cost of tests, two operations, after surgery cares, and other associated costs (like accommodation and travel costs if the patient travels from another city). Insurance companies cover the medical costs of the transplant and the operations are also performed free of charge in state-owned hospitals.
"In addition, the government pays a monetary gift to the donor for appreciation of her altruism (currently, 10m Rials), as well as automatic provision of one year free health insurance, and the opportunity to attend the annual appreciation event dedicated to donors...
"The minimum monthly legal wage for 2007 was Rials 1,830k (later raised to 2,200k for 2008). The minimum payment of Rials 45m is around 2 years of minimum wage. "
...
"[T]o prevent international kidney trade, the donor and recipient are required to have the same nationality. That means an Afghan patient, who is referred to the foundation, should wait until an Afghan donor with appropriate characteristics turns up. This is to avoid transplant tourism. "
...
"the donors are mostly men (Table 7). This can be because of the two facts. Firstly, the ages between 22 and 35; when the donation is accepted; is the fertility age; and women are less likely to be considered as potential donors. Secondly, as we mentioned before since men are supposed as the main breadwinner of the family, it is more likely that they sell their kidneys in order to overcome financial difficulties. Female donors count for around 18% of traded kidneys in our data; it is in contrary with the Indian case where 71% of the sold kidneys were from female donors (Goyal et al. 2002)."
In his sample of 598 transplants (Table 6), 539 were "traded kidneys," 10 "non-traded" and 49 "Cadaver", i.e. the vast majority of kidney transplants were live donor transplants with compensation to the donor.
Among other things, it is full of institutional detail and comparisons. Here are a few things that caught my eye.

This decision has been made because the foundation was worried of a decreasing trend in number of donors.
"In some cases, the recipient will agree to make an additional payment to the donor outside the system; it is not certain how common this practice is, but according to the foundation staff the amount of this payment is not usually big and is thought to be about 5m to 10m Rials (≈ $530 to $1060). The recipient also pays for the cost of tests, two operations, after surgery cares, and other associated costs (like accommodation and travel costs if the patient travels from another city). Insurance companies cover the medical costs of the transplant and the operations are also performed free of charge in state-owned hospitals.
"In addition, the government pays a monetary gift to the donor for appreciation of her altruism (currently, 10m Rials), as well as automatic provision of one year free health insurance, and the opportunity to attend the annual appreciation event dedicated to donors...
"The minimum monthly legal wage for 2007 was Rials 1,830k (later raised to 2,200k for 2008). The minimum payment of Rials 45m is around 2 years of minimum wage. "
...
"[T]o prevent international kidney trade, the donor and recipient are required to have the same nationality. That means an Afghan patient, who is referred to the foundation, should wait until an Afghan donor with appropriate characteristics turns up. This is to avoid transplant tourism. "
...
"the donors are mostly men (Table 7). This can be because of the two facts. Firstly, the ages between 22 and 35; when the donation is accepted; is the fertility age; and women are less likely to be considered as potential donors. Secondly, as we mentioned before since men are supposed as the main breadwinner of the family, it is more likely that they sell their kidneys in order to overcome financial difficulties. Female donors count for around 18% of traded kidneys in our data; it is in contrary with the Indian case where 71% of the sold kidneys were from female donors (Goyal et al. 2002)."
In his sample of 598 transplants (Table 6), 539 were "traded kidneys," 10 "non-traded" and 49 "Cadaver", i.e. the vast majority of kidney transplants were live donor transplants with compensation to the donor.
Market for prayers in Iran
It's not just kidneys; selling prayers in Iran isn't repugnant either.
In Islamic Iran prayer sellers' trade is booming
"TEHRAN (Reuters Life!) - In Islamic Iran where clerics rule, unofficial "prayer sellers," who promise to intercede with the divine to solve all manner of life's problems, are seeing their business boom."
...
"Iran's clerics also believe in the power of prayer but they advise people against using prayers that lack a religious basis. Magic and superstition are both illegal under Islamic law.

"Iran's clerics also believe in the power of prayer but they advise people against using prayers that lack a religious basis. Magic and superstition are both illegal under Islamic law.
"Writing prayers quoting Shia's immaculate Imams and receiving money for that has no legal obstacle," said Grand Ayatollah Lotfollah Safi Golpaygani when asked about the religious legitimacy of the prayer sellers. "
"But referring to prayers written by hustlers without reliable sources is not permitted, and getting money for those kinds of prayers is (religiously) forbidden," he told news website hawzah.net.
"Despite what Iranian clerics say, none of YaAli's customers ask him about the basis of his knowledge, which he says is founded on the Koran.
"It is not important where his knowledge comes from, I just want my problems to be solved," said Marjan, 24, who complains it is getting harder to see YaAli as customer demand increases."

A degree is a degree
"A degree is a degree! Whether fake or genuine, it's a degree! It makes no difference!" Baluchistan province chief minister Nawab Aslam Raisani, who claims a master's in political science, shouted at a gaggle of reporters Tuesday.
This insight is from the news report Fake degree scandal roils Pakistani politics.

Espionage: the market for secret information
The newspapers this morning are full of stories about the arrest of eleven accused Russian spies, e.g. the NY Times reports In Ordinary Lives, U.S. Sees the Work of Russian Agents.
"They had lived for more than a decade in American cities and suburbs from Seattle to New York, where they seemed to be ordinary couples working ordinary jobs, chatting to the neighbors about schools and apologizing for noisy teenagers.
"But on Monday, federal prosecutors accused 11 people of being part of a Russian espionage ring, living under false names and deep cover in a patient scheme to penetrate what one coded message called American “policy making circles.” "
The story in the Harvard Crimson adds an interesting detail: Kennedy School Grad Arrested in Russian Spy Raid.
"Called the “Boston Conspirators” in a complaint filed in the U.S. District Court for the Southern District of New York, Heathfield and Foley are alleged to have met with a “former legislative counsel for US Congress” and a “member of faculty in economics.” The documents redacted the affiliation of the faculty member."
It's true that the publication process in Economics is ridiculously slow, but I thought the internet had removed the need for cells of long term sleeper spies to find out what's in our working papers...

Live kidney donation: how to ask in Chicago
Harvey Mysel, a kidney recipient who went on to found the Living Kidney Donor Network, writes to ask me to let readers know of two workshops he is offering in Chicago in July on Having your donor find you
Signaling you're not 'overqualified' in a recession
The Globe reports on Deflating credentials to land a job.
"As the tight job market forces the unemployed to apply for lower-level positions, more job seekers are “dumbing down’’ credentials, wiping graduate degrees and high-level experience off their resumes, recruiters say. Applicants say the idea is to get hiring managers to at least look at their resumes, instead of figuring someone with extra qualifications will demand a bigger salary or leave for a higher-level opportunity once the economy turns around."
...
“Somebody finds out you know that much more than they do, they get nervous,’’ Carroll said.
"That’s true, says Robert Akerlof, a post-doctoral associate at the MIT Sloan School of Management, who is working on a theory about how it can be difficult to maintain authority over overqualified workers if they think a job, or a boss, is beneath them.
"Dumbing down a resume is a way for job seekers to show that they are going to be respectful, said Akerlof, citing the “20 percent rule,’’ which states that bosses should be 20 percent smarter than their employees.
“I think it’s not so much that you’re lying about what your resume is, it’s that you’re trying to convey an appropriate attitude,’’ he said."

Misc. organ transplant links
A Review of Organ and Tissue Donation Procedures by the Royal Australasian College of Physicians nicely summarizes some of the different ways deceased donor organs are dealt with around the world.
The ‘blood group O problem’ in kidney transplantation—time to change? discusses the Eurotransplant Kidney Allocation System, which apparently allows some O kidneys to go to patients who aren't type O.
Mike Rees' revolution of non-simultaneous non-directed donor chains continues to bear fruit in unexpected ways: LOYOLA PROGRAM A RADICAL SHIFT IN LIVING DONOR KIDNEY TRANSPLANTS
"In a first, four people step forward to donate kidneys to complete strangers across the country with no strings attached."...
"It's extremely rare when someone asking for nothing in return steps forward at a hospital and offers to donate a kidney to a complete stranger.
What's rarer still is what has happened at Loyola University Medical Center -- four people have stepped forward and offered to donate kidneys to four complete strangers and none have asked for a thing in return.
"This is completely unique and totally unheard of," said Garet Hill, founder of the nonprofit National Kidney Registry, which coordinated the donations. "We have never had four donors from one institution come forward at one time to offer up kidneys for donation with no strings attached."
The selfless acts by the four have helped Loyola launch its Pay-it-Forward Kidney Transplant Program, the first of its kind in the Midwest, and the largest number of altruistic donors to ever begin such a program in the United States."
Here's a collection of kidney exchange stories and videos from MSNBC, some rather old: http://article.wn.com/view/2010/05/04/Kidney_swap_program_posts_high_success_rate/
And here's a live donor story: From Fear To Elation: Prepping To Be An Organ Donor
Deceased donor allocation policies are also a very big deal. Alex Tabarrok at MR has a thought provoking post on one aspect of the debate: Optimizing Kidney Allocation: LYFT for LIFE which touches on the issue of how it's often difficult to make changes in health care policy that aren't Pareto improvements, even if they are improvements by other measures.

Decent work research prize
When I read that the International Labour Organization had a Decent Work Research Prize, my initial thought was "finally, a research prize for the rest of us." (It's hard to do exceptional work, but doing decent work seems like an achievable goal...)
But that turns out to be a mis-reading: here's the beginning of the prize description.
"The ILO’s International Institute for Labour Studies has created a research prize to annually reward outstanding contributions to the advancement of knowledge on the ILO’s central goal of decent work for all."
That seems like a good goal too:)

Changing sexual mores in China
Swinger Tests China’s Sex Morals
"On Thursday, a court sentenced Mr. Ma to three-and-a-half years in prison, a severe penalty for a crime that the Chinese government calls “crowd licentiousness.” Mr. Ma, now China’s most famous swinger, remains defiant and plans to appeal, saying his sex life is his own business, not subject to the law as long as he causes no social disturbance, according to his lawyer, Yao Yong’an. "
...
"The case of Mr. Ma, who was arrested last August and went on trial last month, has drawn attention across China not only for its titillating details, but also because it also raises questions about an authoritarian government’s attempts to curb sexual freedom and limit privacy in a society where rapid economic growth and the ubiquity of the Internet have upended traditional values. "
...
"The Communist Party no longer maintains the kind of tight control over people’s private lives that it did decades ago. Yet, some officials still try to prosecute citizens based on laws that seem increasingly out of step with social mores. One example is criminal law 301, under which Mr. Ma and 21 fellow swingers were prosecuted, and which can result in a five-year prison term.
Chinese Internet users and even some official news organizations have debated the case."
...
"The law against group sex, generally interpreted by judges as involving three or more people, is left over from an earlier law against “hooliganism” that was used to prosecute people who had sex outside of marriage, Ms. Li said. The hooliganism law was scrapped in 1997. One notable swingers case took place in the early 1980s, when the leader of a swingers club involving four middle-aged couples was executed, she added.
At least three recent surveys have shown that prosecution of group sex does not enjoy widespread support today.
Several Chinese news Web sites posted editorials echoing that sentiment after the verdict was announced. "

NYU in Abu Dhabi
I've blogged before about the problems of establishing and maintaining universities in places whose culture may be antagonistic to university culture.
NYU seems to be attacking that from an interesting angle in it's Abu Dhabi venture, the modal student will be an American: N.Y.U. Abu Dhabi Scours Globe for Top Students
Abu Dhabi "...is where N.Y.U. will open a campus in September with an inaugural freshman class of 150 students from 39 countries."..."Although the students come from 39 countries, with 43 languages, about a third are from the United States. The next four biggest sources are the United Arab Emirates, China, Hungary and Russia. "
...
"Backed by the open checkbook of the Abu Dhabi government, the wealthiest of the seven United Arab Emirates, N.Y.U. Abu Dhabi scoured the planet for candidates. It called on the Institute of International Education, which administers the Fulbright scholarships, to help it identify 900 of the world’s top high schools, and then pressed the schools for their best students.
Though based in Abu Dhabi, students will be encouraged to spend time at some of N.Y.U.’s 16 other sites, on five continents — more traditional study-abroad centers with short-term or narrowly focused programs. In a promotional booklet, the university sketched out a hypothetical plan for film and media majors, with sojourns in Berlin, Buenos Aires, Prague and New York.
The project carries risks. While Abu Dhabi is a relatively modern, multicultural Muslim state, homosexual acts are illegal and the Internet is censored. And there is no guarantee that the seemingly limitless resources of its oil-rich government will remain so, given the precarious global economy and Middle East politics.
But the Abu Dhabi government has agreed to pay for the entire N.Y.U. project, though neither it nor the university has detailed a price. And the emirate has embraced N.Y.U.’s vision of a liberal arts institution with full access to ideas, books and the Internet. "
...
"Some in the new freshman class, including Mr. Aqel, have already used Facebook to discuss a possible civil rights club. “In a way, it’s almost a challenge because we can’t hold protests,” Mr. Aqel said. “But I think we’ll be able to find creative ways to circumvent restrictions while maintaining respect for our host country.” "

Debra Satz on noxious markets
The Stanford class day speech: Satz to graduates: Some goods should never be for sale by Stanford philosopher Debra Satz, whose interests extend to sales of kidneys
Debra Satz (2008). The Moral Limits of Markets: The Case of Human Kidneys. Proceedings of the Aristotelian Society 108 (1pt3):269-288.
From the news story on her class day address:
"What are the different characteristics of markets? Why do some exchanges prompt "extreme revulsion"? Among the examples Satz raised: child labor, body parts, reproductive services, international arms, addictive drugs.
"What makes particular markets appear undesirable or, in my terminology, noxious?" she asked. The intrinsic nature of certain goods – friendship, a person's good name, various prizes and honor – can immediately diminish their value when they are sold.
There are also extrinsic reasons that make markets noxious, and this was Satz's focus. Is the agent fully aware of the consequences of his or her actions? Do all agents have the same information? Does the market cause extreme harm to individuals? And how extreme does it have to be to make it noxious? Does it cause harm to society?
As Satz said – with a nod to Tolstoy's line about unhappy families – "Each noxious market is noxious in its own way," and there will not be agreement on these issues. For example, the sale of kidneys is among one of the most difficult questions. Sales are illegal in every developed society, she said. Kidneys can be donated altruistically while the donor is alive or after death, but no society makes donation mandatory, even in death. Some would argue that with two kidneys people have more than they need. As of June 10, more than 80,000 Americans were on the waiting list for a kidney, and many of them will die waiting, Satz said. "...
"In closing, Satz threw up two final challenges: "Noxious markets" reflect some of the most fundamental problems of our globe, and they will not go away unless and until the underlying problems are addressed. That will require public debate and a willingness to confront hard issues."

And here's Megan McArdle on Satz: What We Should Feel and What We Should Not Sell
She quotes Satz's book Why Some Things Should Not Be for Sale: The Moral Limits of Markets on the following juxtaposition of moral positions:
"[T]here is a dilemma for those who wish to use the mother-fetus bond to condemn pregnancy contracts while endorsing a woman's right to choose an abortion. They must hold it acceptable to abort a fetus but not to sell it."

Lotteries for private schools
Over at the Education Sector, there's a movie review about school choice.

A review of the film 'The Lottery'

"The Lottery" (2010), directed by Madeleine Sackler. The film opens to a wider audience on June 8. For theater listings, visit: http://www.screenvision.com/s/showing/TheLottery/.
"Newark, N.J., Mayor Cory Booker supports charter schools. But he might hesitate before encouraging everyone to see the new documentary "The Lottery," which follows four young children and their families as they vie for a spot at Harlem Success Academy, a coveted charter school across the river in New York City. In the film, Booker says he no longer attends the lotteries that over-subscribed charter schools like Harlem Success Academy use to select students because they break his heart, and because "a child's destiny should not be determined on the pull of a draw."
"Many who see "The Lottery" will likely share Booker's conflicted feelings. The film does an excellent job of showing both the promise and the limits of charter schools and public school choice. When Booker uses the word "destiny," he's not exaggerating; the families feel that winning or losing this lottery will go a long way to determine their child's future. As one prospective Harlem Success parent says in the film, "They instill in those kids from the beginning that 'my goal is to become a college graduate.' I think that if I had had that type of setting ... I think that would have made a big difference in my life."
"And yet, it's no spoiler to alert audience members that some of the families profiled will lose the lottery; more than 3,000 families apply for 475 seats. Those who stay to attend a neighborhood school will be assigned to one of 23 elementary schools. At 19 of these schools, fewer than half of the students are reading on grade level. In contrast, at Harlem Success Academy, 95 percent of third-graders read at grade level, and 100 percent score proficient on the state math exam. Thus, the stakes for these four particular families are high.
""The Lottery's" strength is in showing the audience the school choice process through the eyes of these families..."

A big kidney exchange involving four DC area hospitals, organized at Georgetown U. Hospital, including a June 15 video on the Early Show with the crowd of patients and donors.
The National Kidney Registry, a private organization, has generated a report about some of their successful activities in organizing kidney exchanges in partnership with a number of hospitals, including many nonsimultaneous chaings: The National Kidney Registry: transplant chains--beyond paired kidney donation by Veale J, and Hil G., Clinical Transplants. 2009:253-64. [I haven't been able to find the whole article yet: Pub Med lists it as "in process," but here's the abstract:]
"Abstract: The National Kidney Registry (NKR) has facilitated more than 100 transplants at 24 centers in the past 2 years and the numbers are rapidly increasing. The NKR has inherent capability for rapid change as innovations are developed and incorporated in the approach to matching donors and recipients in transplant chains. Kidneys are shipped with geotracking devices utilizing existing OPO procedures whenever patients are willing to accept them. This reduces the need for donor travel and increases the geographic area where matches can be made. Out-of-sequence transplants can be performed to improve logistics. Matching software is designed to facilitate chain transplantation and incorporates metrics that help transplant centers develop strategies to improve the chances that their patients can be transplanted. Daily match runs and close attention to repairing broken chains have been critical to growing the number of transplants that can be facilitated. A number of new innovations are expected to increase the opportunities for patients and their potential living donors."

Kidneys are shipped with geotracking devices utilizing existing OPO procedures whenever patients are willing to accept them. This reduces the need for donor travel and increases the geographic area where matches can be made. Out-of-sequence transplants can be performed to improve logistics. Matching software is designed to facilitate chain transplantation and incorporates metrics that help transplant centers develop strategies to improve the chances that their patients can be transplanted. Daily match runs and close attention to repairing broken chains have been critical to growing the number of transplants that can be facilitated. A number of new innovations are expected to increase the opportunities for patients and their potential living donors."

Father's day
Father's Day is a great academic holiday, if you think of academics as being concerned not just with ideas and institutions, but with their whole history and earliest conception. Other kinds of coauthors sometimes have difficulty figuring out who did what. But my wife agrees that my contributions were seminal. She was the biggest contributor in the subsequent, germinal stages. The division of labor has been less clear in the happy, fast decades since.
Happy Fathers' Day to all you fathers and children out there.

Indian weddings in New England: the hotel market
The Boston Globe reports: For hotels, a perfect match--Recession-hit hosts embrace Indian weddings.
"On a hot, sunny Saturday in early May, a raucous wedding procession of women in bright, shimmery saris and men in long embroidered kurtas and sunglasses danced through a hotel parking lot behind a van blaring bhangra beats. The groom brought up the rear on a dappled white horse.
"It was the first time the Marlborough Best Western had hosted a traditional Indian wedding and, in keeping with Indian culture, it was an elaborate, all-day affair, with 450 guests.

"It was the first time the Marlborough Best Western had hosted a traditional Indian wedding and, in keeping with Indian culture, it was an elaborate, all-day affair, with 450 guests.
"Best Western is among the many hotels actively pursuing this lucrative market as they struggle to make up for last year’s recession-diminished revenues.
"The InterContinental Hotel, the Ritz-Carlton, the Taj Boston, and the Westin in Waltham have all hosted Indian wedding expos in the past year. Hyatt Hotels Corp. developed an Indian wedding webinar to educate staff about ceremonial customs, cuisine, even popular brands of alcohol.
"And India New England, a newspaper published in Waltham, has had so much demand from advertisers that it put out two wedding supplements instead of one last year and plans to do the same this year.
“Literally, this market is just exploding,’’ said publisher Upendra Mishra."
..."The weddings, [wedding planner and decorator Shobha Shastry] said, typically range from $50,000 to $150,000 and can go as high as $300,000.
"The average cost of a wedding in Massachusetts, by comparison, is closer to $30,000, according to the research company the Wedding Report Inc."
..."There are about 1,500 Indian weddings a year in the region, according to India New England — more than double the number 10 years ago."

Unraveling of day care
The WSJ reports on the increasingly early reservations being made for day care:Day Care? Take a Number, Baby
"These days, many parents are so intent on getting high-quality care for their kids, that they are signing up at popular child-care centers at the moment they know they are expecting a baby—or before. Some child-care centers don't even offer applications, but merely hand parents a wait-list form. That means some kids spend the first two years of their lives on a day-care wait list.
"These days, many parents are so intent on getting high-quality care for their kids, that they are signing up at popular child-care centers at the moment they know they are expecting a baby—or before. Some child-care centers don't even offer applications, but merely hand parents a wait-list form. That means some kids spend the first two years of their lives on a day-care wait list.
"With more women than ever in the work force, many of the country's roughly 11,000 nationally accredited child-care centers are full to capacity. The rules governing wait lists are roughly the same for all of them: Slots are assigned on a first-come, first-served basis. Infant care usually has the longest wait lists. Siblings of children who are already enrolled typically get first dibs on openings, to keep families together.
"Even so, the decision-making process behind filling these coveted slots is complex.
"Directors must match up age groupings so classmates' napping and eating routines are similar. And they must coordinate children's admission to match the unpredictable "graduation" dates of older children.
"To secure a slot, directors advise wait-listing your child at least a year or more before you expect to need care. Jessica Cavens put her baby-to-be on a child-care wait list last August, as soon as she got the results of her home-pregnancy test. The child-care center director got the good news even before the baby's grandparents. Now, one year later, Ms. Cavens's baby, Peyton, has been promised a coveted slot in August in the infant-care room at Primrose School at Stapleton, Colo.
"Some child-care centers allow parents to wait-list children not yet conceived. At centers franchised by Goddard Systems Inc., with 362 schools in 37 states, directors generally accept a wait-list entry before conception as long as parents pay a refundable deposit, usually of about $200, says Joseph Schumacher, chief executive of the King of Prussia, Pa., company."Other directors accept wait-list entries with no questions asked. "I can't do a pregnancy test," says Vallerie Tribble, director of Innovation Station Child Development Center, Alexandria, Va., owned by Bright Horizons Family Solutions, Watertown, Mass.
"Alyssa Soper, director of Bright Horizons at the Prudential Center in Boston, where wait lists are about a year long, says she gets wait-list requests from families who say "they're trying or thinking about" having a baby.
"It pays to enroll all your kids at the same center. Even signing up an older sibling for after-school care or summer camp at your target center may be enough to earn his or her younger sib a slot."

Misc. kidney exchange news
A May 17, 2010 story: Innovative Transplant Procedure at Emory Opens Door to More Patients in Need
"The Emory Transplant Center at Emory University Hospital in Atlanta has recently opened its innovative Paired Donor Kidney Exchange Program, providing greater hope for patients in need of kidney transplants."
...
"Dr. Newell and his team this past month completed the third paired donor exchange surgeries involving a total of six patients - three donors and three recipients - from Texas, Colorado and Georgia. As part of this, as well as one of the two previous exchanges, Emory partnered with the Texas Transplant Institute in San Antonio, the largest independent paired donor program in the country. The program is led by Adam Bingaman, MD, a former Emory trainee who completed both his residency in general surgery and his PhD work at Emory School of Medicine. "To get the ball rolling initially on our program here at Emory, one of the first things we did was partner with the Alliance for Paired Donation," says Dr. Newell. "APD maintains a database of patients who have incompatible donors from over 50 other transplant centers, and the Alliance runs a computer program once a month to find matches between them.
"After about a year, we decided to focus on developing our own database rather than depending on APD's, and we naturally approached Dr. Bingaman about collaborating," says Newell. "Now, building our own listing of donor-recipient pairs remains paramount, an effort expedited by weekly meetings and consultations. Whenever new candidates are added, the data is shared with Dr. Bingaman's program, further increasing each patient's chance of receiving a compatible kidney from a living donor.""
Here's a paper in the June 2010 American Journal of Transplantation:
Ethical Considerations for Participation of Nondirected Living Donors in Kidney Exchange Programs

ABSTRACT Kidneys from nondirected donors (NDDs) have historically been allocated directly to the deceased donor wait list (DDWL). Recently, however, NDDs have participated in kidney exchange (KE) procedures, including KE 'chains', which have received considerable media attention. This increasing application of KE chains with NDD participation has occurred with limited ethical analysis and without ethical guidelines. This article aims to provide a rigorous ethical evaluation of NDDs and chain KEs. NDDs and bridge donors (BDs) (i.e. living donors who link KE procedures within KE chains) raise several ethical concerns including coercion, privacy, confidentiality, exploitation and commercialization. In addition, although NDD participation in KE procedures may increase transplant numbers, it may also reduce NDD kidney allocation to the DDWL, and disadvantage vulnerable populations, particularly O blood group candidates. Open KE chains (also termed 'never-ending' chains) result in a permanent diversion of NDD kidneys from the DDWL. The concept of limited KE chains is discussed as an ethically preferable means for protecting NDDs and BDs from coercion and minimizing 'backing out', whereas 'honor systems' are rejected because they are coercive and override autonomy. Recent occurrences of BDs backing out argue for adoption of ethically based protective measures for NDD participation in KE.
Paying It Forward
Tulane surgeons performed what is believed to be the first “domino” paired-donor kidney exchange in Louisiana at Tulane Medical Center. Three patients in dire need of a kidney transplant received new organs from people they had never met.

Online labor markets, as an experimental lab
There are a growing number of online labor markets (for a description of a wide range, see Work the New Digital Sweatshops By Jonathan Zittrain).
A recent paper explores their use for conducting experiments: The Online Laboratory: Conducting Experiments in a Real Labor Market by John Horton, David Rand and Richard Zeckhauser . They suggest that Amazon's Mechanical Turk is a convenient venue to do experiments, with some natural advantages (e.g. it's possible to recruit large numbers of participants, who don't need to know they are in an experiment), in which adequate control is possible.
"Abstract: "Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid – both internally and externally – as laboratory and field experiments, while requiring far less money and time to design and to conduct. In this paper, we first describe the benefits of conducting experiments in online labor markets; we then use one such market to replicate three classic experiments and confirm their results. We confirm that subjects (1) reverse decisions in response to how a decision-problem is framed, (2) have pro-social preferences (value payoffs to others positively), and (3) respond to priming by altering their choices. We also conduct a labor supply field experiment in which we confirm that workers have upward sloping labor supply curves. In addition to reporting these results, we discuss the unique threats to validity in an online setting and propose methods for coping with these threats. We also discuss the external validity of results from online domains and explain why online results can have external validity equal to or even better than that of traditional methods, depending on the research question. We conclude with our views on the potential role that online experiments can play within the social sciences, and then recommend software development priorities and best practices. "

Renting art at Brandeis
Can a university profit from artwork it owns (that has been donated to it)? Last year Brandeis University raised a storm by proposing to close its museum and sell its art (see my posts here and here.) Now it has proposed renting some of its art (here's the story from the Brandeis student newspaper, The Justice), and that too has generated some criticism. But the Globe thinks renting rather than selling is supportable, here's their editorial:Brandeis: Renting out art for art’s sake
"Brandeis University is raising eyebrows in the museum world with its plans to lend out artworks for money, but exploring this option is a reasonable way to preserve the financially strapped school’s collection.
"Last year, Brandeis considered closing the renowned Rose Art Museum and selling off some of its 7,500 objects. Had that happened, both the school and the region would have been worse off for it. Now, the Globe recently reported, the school is hiring auction house Sotheby’s as a lending broker. Collecting fees from institutions that might want to display some of the museum’s works could generate badly needed funding and might even increase awareness of the Rose as well."
Update: [6:14:18 AM] Bettina Klaus writes "saw your blogpost on renting art and remembered that my Maastricht neighbors are renting some http://www.bonnefanten.nl/en/art_lease (Bonnefanten Art Lease Contemporary art at your home)

The market for shorthand
When I was in high school in New York City in the 1960's, there was a department called Secretarial Studies that taught typing and shorthand (in two flavors, Gregg and Pitman). The students were mostly girls planning on looking for work as secretaries.
Well, recording machines changed the way people dictated letters (and computers of course changed it again), and nowadays the WSJ reports that you need a translator to recover the contents of old shorthand notes:Do You Know, Offhand, Anyone Who Knows Shorthand?As a Skill Fades, Translators Are in Demand; Ms. Sanders Charges 20.5 Cents a Word
It's probably also hard to find someone to repair buggy whips, not to mention recovering files stored in WordPerfect on floppy disks...
If anyone needs someone who once mastered Scribe (since displaced by TeX), let me know.

Heart transplant pro golfer
Until I read the story, I wasn't sure how to parse this AP headline: Heart Transplant Survivor Gets Shot at US Open
It turns out the headline means the golfer Erik Compton got _a_ shot at playing in the Open. He's a survivor of two heart transplants who wants to make a living playing golf. He's one of 156 players in possession of what he calls a Golden Ticket -- a tee time this week at Pebble Beach to play in the U.S. Open."

Universities and culture
A Campus Where Unlearning Is First reports on the challenges facing the American University in Cairo in its quest to offer an American style education to Egyptian students. It starts with what the university president calls "disorientation."
"During disorientation, the students — 85 percent of them Egyptians — are taught to learn in ways quite at odds with the traditional method of teaching in this country, where instructors lecture, students memorize and tests are exercises in regurgitation."

Live Liver donation tragedy
The Boston Globe reports: At the Lahey, a stunning, rare tragedy--Donor dies in liver transplant attempt.
"A man who agreed to donate part of his liver to help a sick relative died while undergoing the transplant procedure at Lahey Clinic in Burlington two weeks ago, the hospital said yesterday.
"A man who agreed to donate part of his liver to help a sick relative died while undergoing the transplant procedure at Lahey Clinic in Burlington two weeks ago, the hospital said yesterday.
"It was only the third death of an adult living liver donor in the United States in the two decades since the first procedure was done, according to two leading transplant surgeons. A total of 4,036 have been performed.
..."“The safety of the donor is foremost in everyone’s mind,’’ said Dr. James Markmann, chief of transplant surgery at Massachusetts General Hospital. “It is a very safe operation, but the risk is not zero. If you do enough [of these operations], it will happen. Our thoughts go out to the donor’s family. They did a wonderful thing, and it’s tragic that it ended up this way.’’
"Markmann put the risk of death at one or two in 1,000 operations and said the risks to donors are like those for any type of major surgery, including infection, but generally are less because patients are healthy. He said these risks are weighed against the benefits to recipients: 10 to 15 percent of people waiting for a liver donation die each year because of a shortage of cadaver donors. About 1,500 liver transplant candidates died last year across the United States."
"Dr. Giuliano Testa, director of liver transplantation at the University of Chicago Medical Center, said there have been just three deaths of adult liver donors, the last in 2002 at Mount Sinai Medical Center in New York. He called the Lahey team one of the most “experienced and most expert’’ in the country."
..."Until 2001, the number of liver transplants from living donors in the United States had been growing, reaching a peak of 524 that year. Since then the number has declined, with 219 operations performed last year. Of those, 24 were done at Lahey.
"Surgeons said that the Mount Sinai death may have had a chilling effect on living liver donor transplants, but that in 2002 the cadaver liver allocation system was reorganized so that organs went to the sickest patients. This change reduced the need for living donors.
"Of the 323 living donor liver transplants done in Massachusetts since 1994, 215 were performed at Lahey. This is the first donor death since the program began in 1999, the hospital said."

Dating sites that limit your options
A new paper by my HBS colleagues Hanna Halaburda and Misiek Piskorski discusses why a dating/matrimony site that limits your options (like eHarmony) might be attractive. Their paper is called Platforms and Limits to Network Effects
The idea is that, even if you would prefer to have lots of options yourself, you might prefer to be one of a small set of options your dating partners are considering.
Abstract:We model conditions under which agents in two-sided matching markets would rationally prefer a platform limiting choice. We show that platforms that offer a limited set of matching candidates are attractive by reducing the competition among agents on the same side of the market. An agent who sees fewer candidates knows that these candidates also see fewer potential matches, and so are more likely to accept the match. As agents on both sides have access to more candidates, initially positive indirect network effects decrease in strength, reach their limit and eventually turn negative. The limit to network effects is different for different types of agents. For agents with low outside option the limit to network effects is reached relatively quickly, and those agents choose the platform with restricted number of candidates. This is because those agents value the higher rate of acceptance more than access to more candidates. Agents with higher outside option choose the market with larger number of candidates. The model helps explain why platforms offering restricted number of candidates coexist alongside those offering larger number of candidates, even though the existing literature on network effects suggests that the latter should always dominate the former.

College admissions and "demonstrated interest"
Signaling is important, says a recent article in the Chronicle of Higher Ed: The Dynamics of Demonstrated Interest
"This year, American University received a record 17,000 admissions applications, a 13 percent increase over last year.
.... as colleges become more selective, they often find themselves competing with institutions a rung or two higher on the ladders of selectivity and desirability, at least for the top students.
Although there's prestige in this kind of association, there's also uncertainty. How many applicants would turn down a super-selective, big-name college to attend a somewhat less-selective, less-famous one? How do you know whether a student considers your college a top choice or a "safety school"? How does an applicant's sense of "fit" with a college relate not only to matriculation, but also retention?
"In recent years, such questions have prompted American's admissions team to look more closely at "demonstrated interest," the popular term for the contact students make with a college during the application process, such as by visiting the campus, participating in an interview, or e-mailing an admissions representative. In theory, it's a way to measure the likelihood that an applicant will matriculate—and succeed if they do.
"The practice is not new, but its importance has grown at some selective colleges in this era of ballooning applications and economic uncertainty. From 2003 to 2006, the percentage of colleges rating demonstrated interest as a "considerably important" factor increased to 21 percent from 7 percent, according to an annual survey by the National Association for College Admission Counseling. Since then, that number has held steady (another 27 percent of colleges now deem it "moderately important"). ...
"Recently, American has created more opportunities for students to do just that. The admissions office has broadened its recruitment strategies to include online chats for prospective applicants. Participation is noted in each student's file. ...
"Demonstrated interest often dovetails with another strategy for managing uncertainty: the waiting list. This year, American offered a spot on its waiting list to about 2,000 students, a seemingly large number considering that the university had accepted approximately 7,300 students for its freshman enrollment target of 1,450.
"Applicants who received waiting-list invitations from American fit a range of descriptions. Some were less competitive than the applicants the university accepted, but others were top-notch students who did not seem like a good fit for the university. In some cases, the reason was a lack of demonstrated interest, Ms. Alston says."

Teachers who tamper with standardized test scores
"John Fremer, a specialist in data forensics who was hired by an independent panel to dig deeper into the Atlanta schools, and who investigated earlier scandals in Texas and elsewhere, said educator cheating was rising. “Every time you increase the stakes associated with any testing program, you get more cheating,” he said."
From the NY Times story: Under Pressure, Teachers Tamper With Test Scores, reporting that "investigations in Georgia, Indiana, Massachusetts, Nevada, Virginia and elsewhere this year have pointed to cheating by educators. Experts say the phenomenon is increasing as the stakes over standardized testing ratchet higher — including, most recently, taking student progress on tests into consideration in teachers’ performance reviews."
Afghan child weddings
The NY Times writes about the floggings administered to twp runaway child brides, in a story that also includes some interesting background: Child Brides Escape Marriage, but Not Lashes.
The case of Khadija Rasoul, 13, and Basgol Sakhi, 14, from the village of Gardan-i-Top, in the Dulina district of Ghor Province, central Afghanistan, was notable for the failure of the authorities to do anything to protect the girls, despite opportunities to do so.Forced into a so-called marriage exchange, where each girl was given to an elderly man in the other’s family, Khadija and Basgol later complained that their husbands beat them when they tried to resist consummating the unions.

Super duper
Duper of Harvard Got Into Stanford
Student Accused of Lying to Harvard Was Admitted to Stanford, Too
"Adam Wheeler, the Delaware man charged with lying about his credentials to get into Harvard and to secure nearly $50,000 in financial aid and prizes, was later admitted to Stanford as a transfer student, Massachusetts prosecutors said in court documents released Wednesday."
"Cara O’Brien, a spokeswoman for Middlesex Superior Court in Massachusetts, told my colleague Abby Goodnough that the documents reveal that Mr. Wheeler was admitted to Stanford this year as a transfer student for the 2010-11 school year. Massachusetts authorities have said that Mr. Wheeler left Harvard last fall after university officials confronted him with allegations that much of his application for a Rhodes Scholarship had been plagiarized."

Personal data for sale
Web Start-Ups Offer Bargains for Users’ Data
The budgeting Web site Mint.com, for example, displays discount offers from cable companies or banks to users who reveal their personal financial data, including bank and credit card information. The clothing retailerBluefly could send offers for sunglasses to consumers who disclose that they just bought a swimsuit. And location-based services like Foursquare and Gowalla ask users to volunteer their location in return for rewards like discounts on Pepsi drinks or Starbucks coffee.
These early efforts are predicated on a shift in the relationship between consumer and company. Influenced by consumers’ willingness to trade data online, the sites are pushing to see how much information people will turn over."...
"New companies including WeShop, Aprizi, Blippy and Dopplr are trying to exploit the data that people seem so willing to give up. Some are even allowing shoppers to set what terms they want — free shipping, half-price discounts, only fair-trade products. They can also list what they are shopping for, like a gray cashmere sweater under $100, for instance, and let the retailers fight it out for the right to make a sale.
“The whole privacy debate has grown up around people using your data without your permission,” said Antony Lee, chief executive of WeShop. “If you want to use your data to your benefit, that’s for you to do,” Mr. Lee said."

These early efforts are predicated on a shift in the relationship between consumer and company. Influenced by consumers’ willingness to trade data online, the sites are pushing to see how much information people will turn over."...
"New companies including WeShop, Aprizi, Blippy and Dopplr are trying to exploit the data that people seem so willing to give up. Some are even allowing shoppers to set what terms they want — free shipping, half-price discounts, only fair-trade products. They can also list what they are shopping for, like a gray cashmere sweater under $100, for instance, and let the retailers fight it out for the right to make a sale.
“The whole privacy debate has grown up around people using your data without your permission,” said Antony Lee, chief executive of WeShop. “If you want to use your data to your benefit, that’s for you to do,” Mr. Lee said."

Experimental economics and market design
As I prepare my chapter on that subject for volume 2 of the Handbook of Experimental Economics, I've belatedly posted a related paper, which has a section on experiments in market design from which I'll cheerfully borrow:
Roth, Alvin E. " Is Experimental Economics Living Up to Its Promise? , in Frechette, Guillaume and Andrew Schotter (editors), in The Methods of Modern Experimental Economics , Oxford University Press, forthcoming.

Outsourcing online courtship
The Washington Post has a story about services (like Virtual Dating Assistants) that allow online courtship to be outsourced: Online dating assistants help the lonely and busy
"Last June, Valdez, now 25, founded Virtual Dating Assistants -- a company that "specializes in making the dating dreams of busy individuals come true."
"Author Timothy Ferriss popularized the concept when he wrote about outsourcing his online dating accounts to teams of competing writers in his 2007 book, "The 4-Hour Work Week."
"Valdez's Atlanta-based firm is hardly the only outfit to offer such services. Dozens of profile-writing shops such as Arlington County-based TargetLove have popped up in the past few years, and dating coaches are increasingly managing their clients' online pursuits. Not to mention the well-intentioned friends and relatives who have taken over the process for the hapless singles in their lives.
"But Valdez and his team of 45 freelance writers, including Hartshorn, do it all: write a client's profile, pick out potential matches, send introductory e-mails and message back and forth until a date is confirmed. Then they turn over the correspondence and tell the lucky fellow where and when he's meeting Madame X. (And it's almost always that gender dynamic; 80 percent of the firm's clients are men.)...
"Mark Brooks, founder of Online Personals Watch, a site that tracks Internet dating trends, says this type of outsourcing is an ethically questionable form of "misrepresentation." Still, he expects the field to grow.
"Professional matchmakers often charge $5,000 or more a year and have a limited pool of matches. Online dating sites are populated with countless singles but can require more attention than some users are willing to devote. "It may look like instant gratification, like you dive into the pool and instantly come up with a fish, but it doesn't really work like that," Brooks says. "You've got to tap, tap, tap on the keyboard quite a lot to get anywhere."

The market for young soccer players
The NY Times Sunday Magazine reports on How a Soccer Star Is Made . (Shades of both Harry Potter and Ender's Game...)
"The youth academy of the famed dutch soccer club Ajax is grandiosely called De Toekomst — The Future. ...Ajax once fielded one of the top professional teams in Europe. With the increasing globalization of the sport, which has driven the best players to richer leagues in England, Germany, Italy and Spain, the club has become a different kind of enterprise — a talent factory. It manufactures players and then sells them, often for immense fees, on the world market.
...
"Like other professional clubs in Europe and around the world, Ajax operates something similar to a big-league baseball team’s minor-league system — but one that reaches into early childhood. ... for some families, the first time they realize their boys are under serious consideration is when a letter arrives from Ajax requesting that they bring their sons in for a closer look, an invitation that is almost never declined.
...
"Ajax puts young players into a competitive caldron, a culture of constant improvement in which they either survive and advance or are discarded. It is not what most would regard as a child-friendly environment, but it is one that sorts out the real prodigies — those capable of playing at an elite international level — from the merely gifted.
...
"About 200 players train at De Toekomst at any given time, from ages 7 to 19. (All are male; Ajax has no girls’ program.) Every year, some in each age group are told they cannot return the following year — they are said to have been “sent away” — and new prospects are enrolled in their place.
...
"I asked Martin Jol, the coach of Ajax’s first team, if it was difficult for him to nurture young players knowing he would lose them just as their talent blossomed. “I think that is the purpose of Ajax, to develop players and bring them up to the first team as young as possible,” he answered. “And then we sell them, not for peanuts but for a lot of money.”
...
"In the U.S., we think of money as corrupting sport, especially youth sport. At Ajax, it is clarifying. With the stakes so high — so much invested and the potential for so much in return — De Toekomst is a laboratory for turning young boys into high-impact performers in the world’s most popular game. "
...
"Parents pay nothing except a nominal insurance fee of 12 euros a year, and the club covers the rest — salaries for 24 coaches, travel to tournaments, uniforms and gear for the players and all other costs associated with running a vast facility. Promising young players outside the Ajax catchment area usually attend academies run by other Dutch professional clubs, where the training is also free, as it is in much of the rest of the soccer-playing world for youths with pro potential. (The U.S., where the dominant model is “pay to play” — the better an athlete, the more money a parent shells out — is the outlier.)
" How the U.S. develops its most promising young players is not just different from what the Netherlands and most elite soccer nations do — on fundamental levels, it is diametrically opposed.
Americans like to put together teams, even at the Pee Wee level, that are meant to win. The best soccer-playing nations build individual players, ones with superior technical skills who later come together on teams the U.S. struggles to beat. In a way, it is a reversal of type. Americans tend to think of Europeans as collectivists and themselves as individualists. But in sports, it is the opposite. The Europeans build up the assets of individual players. Americans underdevelop the individual, although most of the volunteers who coach at the youngest level would not be cognizant of that.
...
"De Toekomst is not where you come to hear a romantic view of sport. No one pretends that its business is other than what it is. “We sold Wesley Sneijder for a ridiculous amount of money,” Versloot said. “We can go on for years based on what he was sold for.”
...
"Versloot said that, on average, one and a half products of De Toekomst per season will rise to the first team and go on to a significant, well-compensated pro career. Some of the others will gravitate to second- or third-tier pro circuits or the high amateur ranks in the Netherlands, where the best players make “black money,” under-the-table payments. The pressure to emerge from the academy as one of its top products — and to produce them — is immense. “It is always a very tense atmosphere here, for everyone,” Versloot said. “You have to just get used to it.”
...
"Fulham, like Ajax, is often a seller of talent. It recently sold a 20-year-old to Manchester United for seven million pounds, or more than $10 million. “It’s a little ugly talking about the financial terms,” Jennings said. “I don’t like to do it. It feels not too far off from the slave trade."

"Ronald de Jong invited me to go scouting with him one Saturday. He had his eye on a specific target — “a 2004,” he said, referring to a birth year. A 5-year-old whom he had seen and was checking in with every month or so. This boy might not even be in school yet, I pointed out. “I don’t think he is,” de Jong said with a slight smile, as if he recognized the absurdity. “I believe he’s in day care.”

Auction design patents
My market design colleagues and I have tried to put our algorithms for school choice, kidney exchange, and labor market clearinghouses in the public domain. But in one very competitive commercial area of market design, involving auction rules, it is not uncommon for designers to seek patents.
System and method for a hybrid clock and proxy auction is a patent issued on June 1, 2010 to Larry Ausubel, Peter Cramton, and Paul Milgrom. (Here is a link to other auction patents by Ausubel et al.)

National Kidney Foundation: End the Wait
Here's a press release from the NKF: NKF Names Co-Chairs for END THE WAIT! Exec Committee
"Transplant surgeon Dr. Francis L. Delmonico and non-directed kidney donor Bill Singleton were named the first co-Chairs of the END THE WAIT! Executive Committee, the National Kidney Foundation (NKF) announced June 4.NKF launched the END THE WAIT! initiative at the start of 2009 to address the urgent need to increase the number of organs available for transplantation in the United States."The END THE WAIT! initiative is a virtual call-to-arms that the current system of organ donation and transplantation is not sustainable to fulfill the needs of our patients. In collaboration with other major organizations in the kidney care, donation and transplant communities, we are leading this charge to address the inconsistent practices across the United States that are no longer acceptable," said John Davis, National Kidney Foundation CEO. “We know that Dr. Delmonico's vast professional experience as one of the nation's preeminent transplant experts and Mr. Singleton's personal experience as a living donor will help provide the knowledge and perspective needed to move our ambitious agenda forward and implement our END THE WAIT! recommendations.”END THE WAIT! recommendations focus on improving the donation process, eliminating barriers to donation, instituting best practices and increasing living and deceased donation.
The recently-passed Healthcare Reform Bill prohibits insurance companies from denying medical coverage to those with pre-existing conditions. In the past, living kidney donors had been viewed as having a pre-existing medical condition by some insurance companies and denied medical coverage. Certainly, such practices constitute barriers to donation and eliminating that was one of the END THE WAIT! recommendations," Davis added.
“We will continue to fight for patients to receive comparable care from one region of the country to another, for example by maximizing programs such as paired kidney donation that are not currently accessible to all patients,” said Dr. Delmonico, transplant surgeon at Massachusetts General Hospital and Professor of Surgery at Harvard Medical School. “Others priorities will focus on removing disincentives to living donation, including covering all donation-related expenses.”“The list of Americans now waiting for organs continues to increase each day,” said Singleton, a long-time NKF volunteer and former board member who became a kidney donor in December 2009 as part of the largest kidney exchange in the world to date. “I'm committed to helping other potential donors learn more about the process. I know we can help educate people and remove barriers through END THE WAIT!”

A market design collaboration between an economist and computer scientists
I've written earlier about the work on course allocation by Eric Budish. The new mechanism he proposed is by no means computationally trivial to implement, and together with Abe Othman, a computer science grad student at CMU (who took my Market Design class when he was an undergraduate at Harvard), he has been working on making this a practical too. A report of their work has now appeared:
Finding Approximate Competitive Equilibria: Efficient and Fair
Course Allocation, Abraham Othman, Eric Budish, and Tuomas Sandholm, Proc. of 9th Int. Conf. on Autonomous Agents and Multiagent Systems (AAMAS 2010), van der Hoek, Kaminka, Lespérance, Luck and Sen (eds.), May, 10–14, 2010, Toronto, Canada, pp. 873-880
Abstract: In the course allocation problem, a university administrator seeks to efficiently and fairly allocate schedules of over-demanded courses to students with heterogeneous preferences. We investigate how to computationally implement a recently-proposed theoretical solution to this problem (Budish, 2009) which uses approximate competitive equilibria to balance notions of efficiency, fairness, and incentives. Despite the apparent similarity to the well-known combinatorial auction problem we show that no polynomial-size mixedinteger program (MIP) can solve our problem. Instead, we develop a two-level search process: at the master level, the center uses tabu search over the union of two distinct neighborhoods to suggest prices; at the agent level, we use MIPs to solve for student demands in parallel at the current prices. Our method scales near-optimally in the number of processors used and is able to solve realistic-size
problems fast enough to be usable in practice.
