One of the most interesting uses of the internet as a place to work and play and buy and sell and advertise was explored by Second Life , a virtual world in which individuals and companies can purchase and develop virtual real estate, and host customers and guests. On Second Life you could have an avatar that represented you personally, and you could develop an island for yourself or your company. Many companies opened islands to see what would happen, and the news agency Reuters opened a bureau in second life. But The Reuters Second Life bureau is now closed, and some of the early enthusiasm for the site has faded.
One reason for this is that the site became increasingly sexualized, and the management is now taking steps to segregate sexual content from other kinds of commerce: Red Lights Might Save Second Life:
"In a move obviously meant to attract more mainstream users to Second Life and salvage some of the realm's lost momentum, Linden Lab will soon be moving mature content to a secondary continent within the virtual world. This has got to be a relief to all those businesses that wasted precious resources building digital offices and outlets in the pixel-based universe over the last few years.
Once touted as an essential locale for hip businesses to open up their doors, Second Life saw something of a real estate boom as companies such as Dell and IBM rushed to build their presence on Second Life's sprawling landscape. But once built, these massive corporate structures turned out to be little more than vast wastes of time and money--gigantic ghost towns in a non-existent gold rush."
The latest news is that it is now possible to take the technology private, and host your own, private Second Life: Second Life Lives Behind a Firewall.
One of the early users of this technology is Case Western Reserve University: Case Western Reserve U. Debuts Private Version of Second Life (for some reason, the isolated version of Second Life is codenamed "Nebraska." ):
"Case Western is the higher-education test site as Linden Lab, the company that runs Second Life, develops the so-called Nebraska version of the virtual world. The concept is to provide all the functions of Second Life, but to let institutions install the platform on their own servers, in their own data centers, and behind their own security systems. The new platform is “completely disconnected from the main Second Life environment,” according to a Second Life blog.
But why would a school like Case, which already has eight islands in Second Life, want to bother with a stand-alone system?
A medical school interested in performing research involving personal medical histories could use a private environment, Mr. Johnson said. Another function would be programs that focus on both adults and kids. Right now, adults need to undergo background checks to access the Second Life teen grid. One use Case envisions for the Nebraska environment would involve the campus Hispanic club providing mentors to Cleveland public-school students in the online virtual world, said Wendy Shapiro, the university’s senior academic-technology officer.
Oh, and another thing: When you host your own universe, you get “God” privileges.
“You can control everything,” said Ms. Shapiro, sounding excited at the prospect. “You can control who comes in, who gets kicked off. You can control whether people walk or fly.”"

Delaying kindergarten entry
The Telegraph discusses the problem of "summer born children," who would be younger than their kindergarten peers if enrolled according to the usual school schedule: Does it pay to delay the start of your child's schooling?. The article focuses on the American experience:
"A survey by the US Department of Education in 2007 found that 14 per cent of children aged 5 to 6 had delayed entry into school, or had parents who planned to delay their entry. In some areas - most often those where parents can afford an extra year of pricey pre-school - the level can reach as high as 25 per cent of the classroom.
The practice is more common among boys and tends to be concentrated in some geographic areas, though nearly absent in others. “Middle-class parents are savvy about wanting to know what the trends are and wanting to make sure that their kids aren't outside the norm,” says one education professor.
That's what comes across in a recent post on a parenting blog from an anxious mother in New Jersey. “I am thinking of holding my daughter back so she is emotionally ready for kindergarten,” she wrote, “but I'm also thinking about it because I worry that she will be the youngest since everyone else is holding back.”
“It's pernicious,” says Morrison, who is concerned, as are many other educators, about the effects on the rest of the student body.
Already, teachers must reckon with children who are 12 months apart in age - a big difference when they are just 5 years old. “On every dimension you can think of, you are going to have kids stretched out along a continuum,” says Beth Graue, a former kindergarten teacher, who studies school readiness at the University of Wisconsin. “You've got to accept that you are going to have gigantic five-year-old girls and tiny five-year-old boys who are going to want to do different things.” When some children begin school a year later than their peers, the range - and the challenge for the teacher - is that much bigger."
If schools are tournaments, this could make sense:
"The notion that small differences in age might make a big difference on the field is familiar terrain to Malcolm Gladwell, The New Yorker magazine writer and bestselling author. In his latest book, Outliers: The Story of Success, Gladwell studied ice hockey teams in Canada, where the game is high on the list of national priorities.
By the time kids are just 9 or 10, they are already being selected for elite teams, extra training and top coaching, and at that young age, those born nearest to the January 1 cut-off date - the oldest in each year's grouping - are usually the best, with the extra few months giving them a real advantage on the ice. With more special attention, that advantage seems to stick: Gladwell found that in any grouping of elite hockey players, 40 per cent were born in the first three months of the year. "
This sounds a bit like the reverse of unraveling, the process by which transactions become earlier and earlier in some markets. That process can feed on itself; if everyone else is recruiting early, maybe you had better do so also. It sounds like holding children back from school entry could potentially have the same dynamic: if the other children will all be a year older, maybe you should hold yours back too, especially if you're raising a future football player...

College admissions essays: who writes them, and who reads them?
In England, as in the U.S., college applications require an essay. In England, as in the U.S., some students hire professional help, some plagiarize from the internet, and many get some advice from teachers and parents. In England, unlike in the U.S., students also have the right to see the letters of reference that their high school teachers write for them.
In reaction to all this, the University of Cambridge doesn't read the essays anymore, and may not pay much attention to the letters of recommendation: Personal statements mean nothing, says Cambridge admissions head.
"Many toil for months, writing draft after draft with care and attention. Some simply cut and paste somebody else’s work from the internet. Others order tailor-made versions online for as little as £24.99.
However they do it, writing a personal statement extolling their virtues and love of study has become a rite of passage for teenagers applying to university.
Now it turns out that many of them need not have bothered.
The University of Cambridge has admitted that it pays no attention to applicants’ personal statements when deciding whom to interview or offer a place.
“With the profusion of companies and websites offering to help draft applicants’ personal statements for a fee, no admissions tutor believes them to be the sole work of the applicant any more,” said Geoff Parks, the university’s straight-talking director of admissions. Much simpler just to ignore them.
“We certainly don’t assign any marks to personal statements,” he added. “I have been told by students after they have been admitted that their schools write the personal statements. Reading a very good personal statement doesn’t tell you anything about the student because you cannot be sure that it’s the work of the person concerned.”
Although the university may use the personal statement as the basis for discussion during an interview, it is not used to judge the student. At all.
Personal references from teachers are also treated with a huge pinch of salt. Now that students can ask to see their references, teachers have stopped saying anything interesting or controversial, Mr Parks suggests."
...
"A survey of 50,000 university applications two years ago — many of them for places on medical sciences courses and at Oxbridge — found that a significant minority of students had plagiarised them from the internet. The giveaway was the 234 applicants who all began their medical school application with the same anecdote about setting fire to their pyjamas at the age of eight."
The head of admissions at Oxford, however, says they still pay attention to essays, to help them distinguish among their applicants more than they can by just looking at grades and standardized exams.
In reaction to all this, the University of Cambridge doesn't read the essays anymore, and may not pay much attention to the letters of recommendation: Personal statements mean nothing, says Cambridge admissions head.

University admissions in the UK
I've been trying to understand the semi-centralized application process for British universities, run by an organization called UCAS (Universities & Colleges Admissions Service).
It offers a common application process through which applicants can apply for up to five programs of study, with some restrictions. For example, "If you are applying for dentistry, medicine, veterinary medicine or veterinary science, you can apply for a maximum of four choices in any one of these subjects." And you can apply to only one of Oxford and Cambridge.
Students apply (mostly) by mid January, and Universities make their decisions in a decentralized way, and mostly report them back to students and UCAS by the end of March. Offers of acceptance may be either unconditional or conditional on the student achieving certain grades in upcoming exams.
Students who receive at least one offer can make a firm acceptance, an insurance acceptance, or decline. A firm acceptance is a commitment to attend (and a firm acceptance of a conditional offer is a commitment to attend if the student's grades meet the acceptance conditions). A student may firmly accept only one offer, but if that offer is a conditional one, may additionally choose to accept an additional offer as an insurance choice:
"You can accept an offer as an insurance choice if your firm choice is conditional. Your insurance choice can be conditional (CI) or unconditional (UI) and acts as a back-up to your firm choice, so if you do not meet the conditions for your firm choice but meet the conditions for your insurance choice, you are committed to that course. "
An insurance choice is also a commitment, and so students are advised that they don't need to make one.
Students are given individualized reply dates, depending on when their last decision from their five applications was received. Offers not accepted by the reply date are considered to have been declined.
Students who don't receive any offers or who decline all of those they do receive may apply to courses that still have vacancies, one additional application at a time, through a process called Extra. And, later in the year (in the summer), students who still don't have places, for example because they didn't meet the requirements of a conditional offer, can apply for vacant places through Clearing.
Here's a newspaper account from last year's Clearing process:
"Clearing fortnight is always an emotional rollercoaster. There are, after all, few sleepless nights to rank alongside the one before you get your hands on that ominous bit of paper showing your A-level results. But if you find yourself facing a column of grades lower than you’d expected, all is not lost: of the 413,000 university applicants given firm places last summer, nearly one in 10 (39,000) secured them through Clearing.
Find your course online
Thanks to the wonders of modern technology, finding a last-minute place has never been easier. Whereas applicants would once have spent days trying to secure a berth at university – waiting for individual prospectuses to reach them in the post, then painstakingly wading through in search of viable substitute courses – the internet has revolutionised this process.
Today everything can be sorted out within hours: a visit to the Ucas online Track service will confirm whether you have scraped in, or have indeed lost your place, while the Clearing website offers a handy A-Z of courses looking to fill vacancies. "
This year, early newspaper reports reflect worries that cutbacks may mean that relatively fewer places will be available at Clearing: Students face chaos with no clearing places.

Piracy and armed merchantmen
Why is this headline such an outlier? Cruise ship opens fire to beat back Somali pirates
One reason is that ship owners are concerned about the longer term effects of escalating the level of violence in their encounters with pirates. But, it turns out, there are some market design reasons too (emphasis added):
"There have been calls for commercial ships to be allowed to carry weapons to deter increasingly bold pirate gangs, who are armed with automatic rifles and often rocket-propelled grenades.
But ships with arms onboard are not allowed to dock at non-military ports.
To bypass this rule, some operators are hiring private security teams who board as the ship enters a risky stretch of water and leave once the danger has passed.
Andrew Mwangura, head of the East African Seafarers' Assistance Programme in the Kenyan port of Mombasa, criticised the Melody for carrying guns.
"There are a number of other methods which can be used to deter the pirates, having weapons on board is dangerous because it raises the stakes for the pirates," he said.
"There is a far higher risk that a crew member of a merchant vessel, or a passenger, could die if the pirates feel they must fight harder to win the ship." The International Maritime Bureau said piracy incidents nearly doubled in the first quarter of 2009, almost all of them off Somalia. There were 18 attacks off the Somali coast in March alone.
Pirates have made millions of dollars from seizing ships and taking crews hostage. A Greek ship was released on Saturday after a £1.3 million ransom was paid.
But just hours earlier a German grain carrier was grabbed in the Gulf of Aden. "

School choice in Belgium and England
School choice remains a hot topic (both academically and politically) in England and Belgium.
Estelle Cantillon will be giving a paper "School Choice Procedures: How They Matter? Theory and Evidence from Belgium," at a June conference in England: School choice in an international context: learning from other countries' experiences .
François Maniquet has written a paper (in French: Inscriptions dans les écoles : quelques enjeux et quelques solutions ) proposing that a centralized choice algorithm using either the deferred acceptance algorithm or top trading cycles should be employed in school choice in Belgium. Here is some coverage in the Belgian press (also in French): D’abord respecter les préférences scolaires; Solution centralisée pour les inscriptions

Fleeting expletives and wardrobe malfunctions: FCC vs Fox Television and CBS
Can television broadcasters, particularly of live events, be fined if the FCC deems some of the language offensive?
"Taboo language," particularly when broadcast over Federally regulated radio spectrum is a contentious class of repugnant transactions. Some of the relevant jurisprudence was discussed in a memorably titled (and clearly and informatively written) article by the OSU law professor Christopher Fairman: "Fuck," 28 Cardozo Law Review 1171 (2007).
There have been some pretty funny "workarounds" to avoid the wrath of the FCC, such as the frequent use of the neologism "frak" on the now-ended tv series Battlestar Galactica.
All this is brought to mind by the recent Supreme Court review of the case FCC v. Fox Television Stations. The FCC derives its authority to regulate language from regulations regarding sexual content. So the question before the court is, when someone like Bono says that an award is "fucking brilliant," does that statement have sexual content? (Judge for yourself, at around minute 5:40 in this video of the 2003 Golden Globes award in which U2's song "The Hands that Built America" won a best song award for the film The Gangs of NY.)
It's entertaining to read a carefully worded NY Times account of the recent Supreme Court decision sending the case back to a lower court. The column, called Gentlemen Cows in Prime Time, doesn't use any of the offensive words, and the title of the column is explained in the text:
"In 1623, the English Parliament passed legislation to prohibit “profane swearing and cursing.” Under that law, people could be fined for uttering oaths like “upon my life” or “on my troth.” In the Victorian era, the word “bull” was considered too strong for mixed company; instead, one referred to “gentlemen cows.” Times change, notwithstanding the fervent wishes of prescriptivists to keep dirty words dirty. "
Another account in plain (Anglo-Saxon) English: You Can't Say That On Television, makes it easier to understand the context of the case.
The Supreme Court also sent back to a lower court the case of Janet Jackson's Superbowl "wardrobe malfunction." The FCC had fined CBS, an appeals court eventually overturned the fine, and now the issue is up for grabs again: Court Sends Janet Jackson Case Back for Review.
"The high court on Monday directed the 3rd U.S. Circuit Court of Appeals in Philadelphia to consider reinstating the $550,000 fine that the Federal Communications Commission imposed on CBS over Jackson's breast-baring performance at the 2004 Super Bowl.
The order follows the high court ruling last week that narrowly upheld the FCC's policy threatening fines against even one-time uses of curse words on live television.
In a statement, CBS said the Supreme Court's decision was not a surprise given last week's ruling and expressed confidence the court will again find the incident was not and could not have been anticipated by the network.
Last year, the appeals court threw out the fine against CBS, saying the FCC strayed from its long-held approach of applying identical standards to words and images when reviewing complaints of indecency.
The appellate court said the incident lasted nine-sixteenths of one second and should have been regarded as "fleeting." The FCC previously deviated from its nearly 30-year practice of fining indecent broadcast programming only when it was so "pervasive as to amount to 'shock treatment' for the audience," the court said.
The FCC appealed to the Supreme Court. The case had been put off while the justices dealt with a challenge led by Fox Television against the FCC's policy on fleeting expletives.
The case is FCC v. CBS Corp., 08-653. "

Open source software
A new NBER working paper discusses the creation of "open source" marketplaces:
Half a Century of Public Software Institutions: Open Source as a Solution to Hold-Up Problem by Michael Schwarz, Yuri Takhteyev #14946 http://papers.nber.org/papers/W14946 (and an ungated version here)
As the title suggests, the paper is about (avoiding) the problem of holdup that would arise if you make a lot of complementary investments in particular software, but are then vulnerable to arbitrary increases in its price. Part of the paper's considerable charm is a long section on the history of open source software (which, because it is not proprietary, avoids much of the holdup problem). Two sections which I excerpt from below concern the 1950's, and the 1960's-'70's.
SHARE and FORTRAN
"Early on, however, IBM also had a different idea for reducing customers’ programming expenses: encouraging the clients to share software with each other. It pursued this strategy by setting up an association for its users in 1952, with a mission of helping IBM customers help each other (CampbellKelly 2003). The association was later renamed “SHARE,” the new name explicitly representing the objective of sharing knowledge and software..."
An early contributor of shared software was United Aircraft:
"To understand United Aircraft’s interest in getting other organizations to use their software for free, and in fact their readiness to put additional resources into modifying it to suit the needs of some of the other SHARE members, we must consider, first of all, that United Aircraft already had an assembly program (UASAP) that it had written for its own needs, and quite likely had made a complementary investment into software written for it. If UASAP were accepted as the standard by other members, United Aircraft could benefit from the future software that other organizations would write for it and at the same time get to keep the software that it had written for UASAP."
ARPANET and Unix
"While modern open source institutions diverge substantially from scientific institutions, both in how they attract external funding and in their handling of credit, they share important characteristics and have clear historical links, the ARPANET project being an important opportunity for a transfer of institutions."
"Among the less successful projects funded by ARPA in 1960s was a new operating system called “Multics.” Multics promised to deliver features that were of interest to AT&T and that IBM had been willing to provide in its software (Ceruzzi 2003, p. 156). AT&T’s Bell Laboratories then joined the Multics project with the hope of accelerating it and steering it closer to AT&T’s needs (Ceruzzi 2003, p. 155, also Salus 1994, p. 26). The Multics project failed, likely due to its excessive complexity. However, a number of Bell Labs researchers produced a simplified version of Multics which they called “Unix.” Unix proved an immediate success."

"In 1973 Unix was rewritten in C, a new language also developed at AT&T. While FORTRAN and COBOL had already enabled portability for certain kinds of software, a combination of C and Unix made it possible to write almost any software in a way that would allow it to be moved between computers. Doing so, however, required access to the source code, because different binary software had to be generated for each machine and modifications to the source code were often required. Being able to move software between computers also meant being able to use it on later computers, increasing the time horizons for software users. While much of the software written in 1960s (including all of the ARPANET software) was hardwarespecific and could be expected to become obsolete eventually, most of the software written for Unix in 1970s can be used today. Increased time horizons made access to source code even more important, as some users could now plan to use their software for decades."
The paper goes on to trace how changes in copyright law and the rise of cheap personal computers influenced the open source movement, including the marketing effort that led to the name "open source" replacing "free software".
Half a Century of Public Software Institutions: Open Source as a Solution to Hold-Up Problem by Michael Schwarz, Yuri Takhteyev #14946 http://papers.nber.org/papers/W14946 (and an ungated version here)
As the title suggests, the paper is about (avoiding) the problem of holdup that would arise if you make a lot of complementary investments in particular software, but are then vulnerable to arbitrary increases in its price. Part of the paper's considerable charm is a long section on the history of open source software (which, because it is not proprietary, avoids much of the holdup problem). Two sections which I excerpt from below concern the 1950's, and the 1960's-'70's.
SHARE and FORTRAN
"Early on, however, IBM also had a different idea for reducing customers’ programming expenses: encouraging the clients to share software with each other. It pursued this strategy by setting up an association for its users in 1952, with a mission of helping IBM customers help each other (CampbellKelly 2003). The association was later renamed “SHARE,” the new name explicitly representing the objective of sharing knowledge and software..."
An early contributor of shared software was United Aircraft:
"To understand United Aircraft’s interest in getting other organizations to use their software for free, and in fact their readiness to put additional resources into modifying it to suit the needs of some of the other SHARE members, we must consider, first of all, that United Aircraft already had an assembly program (UASAP) that it had written for its own needs, and quite likely had made a complementary investment into software written for it. If UASAP were accepted as the standard by other members, United Aircraft could benefit from the future software that other organizations would write for it and at the same time get to keep the software that it had written for UASAP."
ARPANET and Unix
"While modern open source institutions diverge substantially from scientific institutions, both in how they attract external funding and in their handling of credit, they share important characteristics and have clear historical links, the ARPANET project being an important opportunity for a transfer of institutions."
"Among the less successful projects funded by ARPA in 1960s was a new operating system called “Multics.” Multics promised to deliver features that were of interest to AT&T and that IBM had been willing to provide in its software (Ceruzzi 2003, p. 156). AT&T’s Bell Laboratories then joined the Multics project with the hope of accelerating it and steering it closer to AT&T’s needs (Ceruzzi 2003, p. 155, also Salus 1994, p. 26). The Multics project failed, likely due to its excessive complexity. However, a number of Bell Labs researchers produced a simplified version of Multics which they called “Unix.” Unix proved an immediate success."

Auctions of airport slots: dead in the water, again.
The latest news on plans to auction off takeoff and landing slots at NY's LaGuardia airport: DOT scraps auction plan for NYC airports .
NYC's airports are the most congested in the nation, but plans for an auction have been politically troubled from the start (see some of my related earlier posts). What is the nature of the politics? Perhaps some of the airlines that fly in and out of NYC airports actually like the congestion, since it keeps out new competition by preventing airlines that don't presently have any slots from getting any.
Freakonomics has a non-auction suggestion for relieving the congestion: Shut Down LaGuardia.

Non-simultaneous trades in basketball
One of the pleasures of market design--a pleasure it shares with good gossip--is being able to explore in detail the rules by which other people live. The NBA Salary Cap FAQ is full of such details.
It turns out that some details involved in managing an NBA team have something in common with the non simultaneous kidney exchange chains I recently blogged about. This is because NBA teams can exchange players, but the Salary Cap imposes some constraints:
What are the rules regarding trades?
"Teams under the salary cap may make trades as they please, as long as they don't end up more than $100,000 above the salary cap following a trade. But if a team is over the cap, or they are under the cap and a trade would take them more than $100,000 over the cap, then an exception is required. An exception is the mechanism that allows a team to make trades or sign free agents and be over the salary cap. Since teams are usually over the salary cap, trades are usually accomplished using exceptions."
What is the Traded Player exception?
"The Traded Player exception is the primary means used by teams over the cap for completing trades. It allows teams to make trades that leave them over the cap, but it places several restrictions on those trades. Trades using the Traded Player exception are classified into two categories: simultaneous and non-simultaneous. As its name suggests, a simultaneous trade takes place all at once. Teams can acquire up to 125% plus $100,000 of the salaries they are trading in a simultaneous trade. For example, a team trading a $5 million player in a simultaneous trade can receive one or more players whose salary is no more than 125% of $5 million, plus $100,000, or $6.35 million in return.
A non-simultaneous trade may take up to a year to complete. "
What is a non-simultaneous trade?
"A trade in which more than one player is traded away can only be simultaneous; non-simultaneous trades are allowed only when a single player is traded away (although teams can sometimes find ways to configure multi-player trades as multiple single-player trades which are non-simultaneous).
Here is an example of a non-simultaneous trade: a team trades away a $2 million player for a $1 million player. Sometime in the next year, they trade a draft pick (with zero trade value itself) for a $1.1 million player to complete the earlier trade. They ended up acquiring $2.1 million in salary for their $2 million player -- they just didn't do it all at once, or even necessarily with the same trading partner.
In the above example, after the initial trade of the $2 million player for the $1 million player, it was like the team had a "credit" for one year, with which they could acquire up to $1.1 million in salaries without having to send out salaries to match. ....
"Here is a more complicated example of a legal non-simultaneous trade: a team has a $4 million Traded Player exception from an earlier trade, and a $10 million player it currently wants to trade. Another team has three players making $4 million, $5 million and $7 million, and the teams want to do a three-for-one trade with these players. This is legal -- the $5 million and $7 million players together make less than the 125% plus $100,000 allowed for the $10 million player ($12,600,000), and the $4 million player exactly fits within the $4 million Traded Player exception. So the $4 million player actually completes the previous trade, leaving the two teams trading a $10 million player for a $5 million and a $7 million player. From the other team's perspective it's all just one big simultaneous trade: their $4 million, $5 million and $7 million players for the $10 million player. "

Organs for transplant in Japan
The London Times reports on the shortage of transplantable organs in Japan, where deceased donation is very limited due to the legal requirement of cardiac death. The article is about future possibilities of cloning human organs in sheep. Nearer at hand, the article describes how the organ shortage in Japan is made more serious by the decreasing availability of organ transplants overseas, through growing restrictions on "transplant tourism": Japanese scientist claims breakthrough with organ grown in sheep:
"The reason for Professor Hanazono’s sense of urgency — and for the entire organ harvest project being undertaken at the Jichi Medical University — lies many miles away in Tokyo and with a historical peculiarity of the Japanese legal system.
Japan defines death as the point when the heart permanently stops. The concept of brain death — the phase at which organs can most effectively be harvested from donors — does exist, but organs cannot be extracted at that point.
The long-term effect of the legal definition has been striking: organ donation in Japan is virtually nonexistent, forcing many people to travel abroad in search of transplants. In the United States, the rate of organ donors per million people is about 27; in Japan it is under 0.8.
The effect, say paediatricians, has been especially severe for children. The same law that discounts brain death as suitable circumstances for organ donation broadly prevents children under 15 from allowing their organs to be harvested.
To make matters worse, international restrictions on transplant tourism are becoming ever tougher, making Japan’s position even more untenable. To avert disaster, say doctors, Japan either needs the science of synthetic organ generation to advance faster than seems possible, or it needs a complete rethink on the Japanese definition of death. "

Market for concierge health care
Is it hard to get an appointment with your doctor, who must see patients every fifteen minutes? Perhaps you are in the market for concierge health care (as described in these two stories, one from 2005 and one from this past Sunday):
For a Retainer, Lavish Care by 'Boutique Doctors'
Despite Recession, Personalized Health Care Remains in Demand
"One promise made to patients paying for concierge service is that waiting will not be a part of their health care experience. Patients are guaranteed that phone calls will be returned promptly, appointments will be scheduled on a same-day basis if necessary, and appointment times will be honored. ...
"A relatively simple tradeoff is responsible: the extra fees collected from patients let concierge doctors, who leave regular practice for concierge medicine, slash their caseloads. Before Dr. Kaminetsky became a concierge doctor five years ago he had 2,500 patients in his practice - a standard number for most primary care internists. His list now numbers 600. "
"The practices typically charge at least $1,500 a year, with the most elite services asking $25,000 or more per family. The fees cover a thorough physical exam and enable physicians to limit the number of patients they see so they can provide premier service. "...
"Critics of concierge medicine consider it elitist and say it has widened the already significant class disparities in American medicine. They also say it has exacerbated the shortage of primary care physicians by leaving more patients to be treated by a shrinking pool of doctors.
But advocates counter that the concierge movement reflects deep exasperation with the two-hour waits and 10-minute appointments of conventional primary care. Given the burnout among physicians who must see more than two dozen patients a day, they say the concierge model may sustain doctors who would otherwise hang up their stethoscopes.
Dr. Thomas W. LaGrelius of Torrance, Calif., who leads the Society for Innovative Medical Practice Design, a professional association of concierge physicians, estimated that there were 5,000 such doctors in the United States, out of an estimated 240,000 internal medicine physicians and related subspecialists. "

Horse meets versus horse meat
The question of Why can't you eat horse meat in the U.S.? takes on special force when the horses in question are retired race horses. The NY Times reports that the slaughter of such horses for human consumption arouses special repugnance.
The article Ignoble Endings Far From Winner’s Circle reports(emphasis added):
"The most significant source of racehorse deaths is the slaughter industry, one driven by overbreeding and demand from the lucrative global meat market. According to the American Society for the Prevention of Cruelty to Animals, more than 100,000 American horses are slaughtered each year in Canada and Mexico to satisfy horse meat markets in Europe and Asia.
The slaughter of domestically bred horses represents a breach of the American covenant between horses and humans: horses bred for sport, industry and agriculture are not part of our food chain. They are not supposed to meet death in a slaughterhouse."
...
"Many owners, faced with the choice of keeping retired horses and continuing to pay for their feed and care, instead opt to sell them at auction for $300 to $500 a horse, not realizing or not caring that if they are exported they can eventually be slaughtered.
“We’ve got lots of work to do here,” Waldrop said. “The problem is far from being solved. There is a high demand for horse meat around the world, and they create a market for horses that competes with our efforts to adopt and retrain these horses.”
The last of the horse slaughterhouses in the United States were shut down in 2007. But at least four states — Montana, Illinois, North Dakota and Tennessee — have either proposed or contemplated legislation to reintroduce horse slaughter. Two bills stuck in committee in the House and the Senate would make it illegal to transport horses across state lines or to foreign countries for the purpose of slaughter. The industry should push Congress to pass pending anti-slaughter legislation."

Market for adultery, in a recession
In an earlier post, I mentioned a website that caters to married people seeking an affair. It turns out that the business is countercyclical:
Adultery business cashes in on world's recession worries
"At the Ashley Madison agency, which revels in the motto, "Life is short. Have an affair," the global economic downturn is proving a boon for business. "
"Membership has soared from one million to 3.6 million in just 12 months, and he expects another surge after the company launched a service allowing members to access the site from their mobile phones. The innovation is aimed at would-be cheaters who are nervous about leaving evidence of their infidelity on their computer at home or work.
Mr Biderman said that many couples who would otherwise have divorced were seeking affairs at the moment because of the cost of hiring lawyers and the difficulty of selling the marital home. "

Marriage and dating online in Korea
Soohyung Lee has a paper about an online marriage market in Korea, whose findings are similar in some respects to those in the papers described in my two earlier posts today, and different in others: Preferences and Choice Constraints in Marital Sorting: Evidence From Korea.
Like the paper by Hitsch, Hortaçsu, and Ariely, Lee's paper considers detailed transactional data from an online site, this one aimed at marriage rather than more casual dating, and uses the data to estimate preferences for mates, based on a variety of observable traits. Like both Hitsch et al. and the paper on Indian marriages by Banerjee, Duflo, Ghatak and Lafortune, Lee's paper looks at stable matches produced by a deferred acceptance algorithm based on the estimated preferences, and compares them to the observed marriages in population data. Unlike those two papers, the findings in Korea are that the simulated stable matchings look different than the population matchings; they are less assortative on some dimensions (such as employment in the same industry).
The paper suggests that some aspects of Korean marriage data therefore reflect choice constraints on who meets whom, and that as these constraints are relaxed (perhaps by increased use of internet matchmaking), some aspects of Korean life may change.
Market design update (5/12/09): Professor Lee sends me the following email describing how her work has proved useful in the design of the matching site, which uses an algorithm to suggest several possible dates to each participant:
"FYI, the matchmaking company partially adopted my estimates to adjust its matching algorithm. Previously, it assumed all men and all women have the same preference ranking. Under the revised algorithm, it classifies men and women based on their characteristics and allows them to have heterogeneous preference rankings (which I find in my estimation).
With the revised algorithm, the company was able to increase the probability of a proposal turning into an actual first date by a factor of 2. "

Marriage and dating online
Günter J. Hitsch, Ali Hortaçsu, and Dan Ariely have a paper about online dating and matching forthcoming in the AER: Matching and Sorting in Online Dating.
They write
"Using a novel data set from an online dating site, we first estimate mate preferences and then use the classic Gale-Shapley algorithm to predict matching outcomes. Online dating exists to facilitate the search for a partner. Our results suggest that the particular site that we study leads to approximately efficient matching outcomes (within the set of stable matches), and that search frictions are mostly absent. Hence, the site appears to be efficiently designed."
Their dataset allows them to look at all the clicks and messages of a subset of participants. So they can see which profiles people look at, and whom they choose to contact. This allows them to form estimates about preferences (on the assumption that if you browse two profiles and contact one of them, you prefer the one you contacted.) And they can observe when email addresses or phone numbers are mutually exchanged, which gives them their proxy for matches.
They compare the matchings they see both to marriages in the population at large (from Census data), and to stable matchings obtained by running the deferred acceptance algorithm, using the estimated preferences. They write:
"We saw that both actual marriages and the predicted matches from the Gale-Shapley model exhibit strong intra-ethnicity sorting patterns. However, even in the absence of search frictions it is not obvious whether same-race preferences alone cause sorting within ethnicity groups: because other attributes, such as income and education, are correlated with race, preferences over these other attributes could lead to intra-ethnicity sorting as well. To investigate what fraction of the predicted endogamy patterns is driven by same-race preferences, we remove these preferences from the utility specification and simulate the corresponding stable matches. Tables 10 and 11, panel (IV), show that intra-ethnicity sorting is strongly diminished, although small degrees of endogamy remain. These results suggest that racial sorting is mostly due to the same-race preferences; preferences for non-race attributes can not quantitatively account for the small fraction of marriages across different ethnic groups."

Marriage market in India
A recent paper by Abhijit Banerjee, Esther Duflo, Maitreesh Ghatak and Jeanne Lafortune studies marriage in Bengal: Marry for What? Caste and Mate Selection in Modern India .
The nature of this marriage market (in which courtship begins with ads and letters) allows the authors to gather data on preferences for mates, by interviewing matrimonial advertisers about their preferences over the letters they receive, and then to follow up to determine eventual marriages.
"First, the parents or relatives of a prospective bride or groom place an ad in the newspaper. Each ad indicates a PO box (provided by the newspaper), and sometimes a phone number, for interested parties to reply. They then get responses over the next few months (by mail or by phone), and elect whether or not to follow up with a particular response. While ads are placed by both sides of the market, "groom wanted" ads represent almost 63 percent of all ads placed.
When both parties are interested, the set of parents meet, then the prospective brides and grooms meet. The process takes time: in our sample, within a year of placing an ad, 44 percent of our sample of ad-placers whom we interviewed, were married or engaged although most had placed only a single ad. Of those who got married, 65 percent met through an ad, the rest met through relatives or, in 20 percent of the cases, on their own (which are referred to as "love marriages")."
They find that preferences for caste are very high (emphasis added):
"These alternative estimations methods lead to very similar qualitative conclusions: education, beauty, light skin, and high incomes are preferred. But the most striking result is that the preference for mating within one's own caste is strong: for example, we find in one specification that parents of a prospective bride would be willing to trade off the difference between no education and a master's degree to avoid marrying outside their caste. For men seeking brides, it is twice the effect of the difference between a self-described "very beautiful" woman and a self-described "decent-looking" one."
But they find that the cost of satisfying these preferences is not large, since supply and demand are well balanced within each caste, so that assortative matching that takes account of caste does not look different than simulated assortative matching on other observables when caste is ignored.
Overall, they conclude that matchings are stable, in the sense of the two-sided matching literature, i.e. they find that search and matching frictions are low enough, or preferences well enough aligned, so that matches simulated by the deferred acceptance algorithm are hard to distinguish from those they observe.

The nature of this marriage market (in which courtship begins with ads and letters) allows the authors to gather data on preferences for mates, by interviewing matrimonial advertisers about their preferences over the letters they receive, and then to follow up to determine eventual marriages.
"First, the parents or relatives of a prospective bride or groom place an ad in the newspaper. Each ad indicates a PO box (provided by the newspaper), and sometimes a phone number, for interested parties to reply. They then get responses over the next few months (by mail or by phone), and elect whether or not to follow up with a particular response. While ads are placed by both sides of the market, "groom wanted" ads represent almost 63 percent of all ads placed.
When both parties are interested, the set of parents meet, then the prospective brides and grooms meet. The process takes time: in our sample, within a year of placing an ad, 44 percent of our sample of ad-placers whom we interviewed, were married or engaged although most had placed only a single ad. Of those who got married, 65 percent met through an ad, the rest met through relatives or, in 20 percent of the cases, on their own (which are referred to as "love marriages")."

Repugnant transactions concerning brides
From the sale of child brides in Saudi Arabia to the difficulty of enforcing the laws against Suttee (self-immolation on the husband's funeral pyre) in India, marriage is a fertile area of contention about practices that many find repugnant even in cases that the parties themselves may not.
In Saudi Ariabia, a small victory for social liberals in the contest with social and religious conservatives over whether sales of children into marriage are a repugnant transaction: Victory for Saudi girl, 8, sold by her father to a 50-year-old man
"The girl, who has not been named and who has been living with her mother in the city of Onaiza, was given to the older man in marriage by her father to pay off a debt." ...
Human rights groups in Saudi Arabia and abroad have condemned the practice of child marriages. "
...
"Some attempts are being made to strengthen women’s rights. The Justice Ministry is reported to be considering reforms to impose a minimum age for marriage and to end abuses of the system by fathers of girls.
In February King Abdullah appointed Norah al-Fayez as the Deputy Minister for Women’s Education, the first woman minister in the kingdom. It has also signed up to the UN Convention on the Rights of the Child.
Despite such efforts, many traditionalists in positions of influence in government and religious life are becoming more strict in their observance of Islamic law. The country’s highest religious authority, Grand Mufti Sheikh Abdul Aziz al-Shaikh, has said that it is not against Islamic law to marry girls under the age of 15."
In India, suttee has been illegal since the 1800's, but in some Indian communities it continues to be thought of as a source of honor, and it has been difficult to entirely eradicate, in part because some instances seem to be voluntary decisions by the wives.
Like the sale of child brides in Saudia, the prospect that some of these instances may not be voluntary casts them in a different light, and changes the debate from one that might resemble the controversies involving assisted suicide to the more straightforward debates about human trafficking and murder. But the discussion is complicated by the fact that, in both Saudi Arabia and India, there is a not insubstantial community that finds such transactions appropriate.

Austin Hoggatt: 1929-2009
Austin Hoggatt, professor emeritus at the Haas School, dies at age 79
"Hoggatt served as the director of UC Berkeley's Computer Center from 1961-62. At the business school, he co-founded the Management Science Laboratory with Professor Fred Balderston in 1968 and served as its chairman. Haas School Professor Thomas Marschak said the lab, which was funded by the National Science Foundation, was the first to run computer simulations in game theory and experimental economics with human-to-computer interface.
...
"He was a pioneer in computing even before the field of computer science had emerged," said Marschak, who remembered Hoggatt collaborating with German Nobel Laureate Reinhard Selten on experimental economics and with faculty colleagues Julian Feldman and Edward Albert Feigenbaum, who went on to do groundbreaking research in artificial intelligence.
Hoggatt and Balderston co-authored an influential book, "Simulation of Market Processes," that was based on computer simulations they had conducted on the lumber industry. "The book was a breakthrough because this kind of analysis of an entire industry was not possible before the advent of computers," said Marschak."

NYC school chancellor Klein on kindergarten waitlists
NYC school chancellor Joel Klein has a straightforward description in the current issue of The Villager of the waiting list situation for Manhattan kindergartens. (He can't magically make overcrowding go away, but he can explain clearly what is going on. NYC seems to be pretty fortunate in some of its top public servants...) Here are his comments in their entirety.
A new equity and transparency in school admissions
By Joel Klein
"Registering your child for kindergarten is often stressful — many of you are preparing to send your son or daughter to school for the first time. Reports of kindergarten wait lists for the fall at public schools in District 2 have added to the anxiety this year. I want to assure families in the community that we’re taking steps to enroll all students who have applied for kindergarten as quickly and fairly as possible.
Let me begin with the facts. A total of six District 2 elementary schools have wait lists for their zoned students: P.S. 6, P.S. 59, P.S. 183 and P.S. 290 on the Upper East Side; and P.S. 3 and P.S. 41 in the West Village (although there is one combined wait list for these two schools). In all of District 2, a total of 242 students are on a wait list at the school they are zoned for. This is a much smaller number than recent news accounts have reported.
These wait lists are the result of two changes we made to the kindergarten admissions process this year. First, we eliminated the practice of first-come, first-served admissions that many schools used in the past, which gave an advantage to well-connected parents who knew when a particular school would begin registering students, and had time to wait in line that first day. Instead, this year each school accepted kindergarten applications until March 6; schools then admitted students based on a clear list of priorities, with the highest being given to the students living within the school’s zone.
Second, we asked all schools to maintain wait lists of students to whom they could not immediately guarantee a seat. Every spring it is common for schools to receive more applications from zoned students than they can actually enroll. The difference this year is that schools registered only students to whom they could guarantee a seat and placed all other applicants on a wait list. This change gives parents a clearer picture about their children’s chances of being able to attend a particular school. It also lets us immediately identify schools that are experiencing a surge in demand and work with them to find ways to accommodate it. In the past, these issues were not addressed until September.
If you’re a parent of a student on a wait list, however, you’re understandably frustrated and confused; it’s reasonable to want to know now where your child will attend school in September.
The answer is that she will almost certainly attend her zoned school. This is because three factors are reducing wait lists even as you read this. Let’s use P.S. 3 and P.S. 41, where there are currently a combined 90 zoned students waiting for a seat, as an example.
We are considering relocating the pre-kindergarten programs at P.S. 3 and P.S. 41 to nearby locations for the 2009-’10 school year. This move will open as many as 75 additional kindergarten seats at the schools, which we will offer to students on the wait list within the next week.
Second, 26 students who are zoned for P.S. 3 and P.S. 41 qualified for kindergarten gifted and talented programs this year. Many of these students either have a seat at one of the schools or are on the wait list, but will instead choose to enroll in the gifted program that we will offer them next month.
Finally, some families who accepted kindergarten placements will ultimately decide to enroll in a nonpublic school or a school outside New York City. This happens every year as families weigh their educational options, but this year’s application deadline gave families an additional incentive to apply to their zoned school — even if there was only a small chance they would want their child to attend.
All of this means that many of the students currently on the wait list at P.S. 3 and P.S. 41 will receive a placement at one of the two schools by the end of next month. Any students who remain on the wait list are still guaranteed a kindergarten seat. These students will receive a placement at a nearby school by the end of June and will be able to remain on the wait list at P.S. 3 and P.S. 41. Seats will likely open up for these students before the start of the school year, since families often move over the summer.
The combination of these three factors will also reduce or eliminate wait lists on the Upper East Side and Upper West Side. There, too, the few students who do not have a placement by the end of next month will receive one at a nearby school.
No explanation I can give will fully make up for the stress and inconvenience of being placed on a kindergarten wait list. But whether you have a child on a wait list or not, I hope you can recognize that we’re trying to bring equity and transparency to an admissions process which did not have either before this year. The families we welcome into our schools every year deserve nothing less, and the placement of every child is important to us. "

Same sex marriage in Maine
New England is now clearly the region of the country most hospitable to same sex marriage (not even counting the honorary New England state of Iowa): Maine Governor Signs Same-Sex Marriage Bill . And Maine continues the trend of having its elected politicians, not just judges, reverse this ancient repugnance.
"Gov. John Baldacci of Maine signed a same-sex marriage bill on Wednesday minutes after the Legislature sent it to his desk, saying he had reversed his position because gay couples were entitled to the State Constitution’s equal rights protections.
“It’s not the way I was raised and it’s not the way that I am,” Mr. Baldacci, a Democrat, said in a telephone interview. “But at the same time I have a responsibility to uphold the Constitution. That’s my job, and you can’t allow discrimination to stand when it’s raised to your level.”
Yet gay couples may not be able to wed in Maine anytime soon. Laws typically go into effect 90 days after the Legislature adjourns, which is usually in late June. But opponents have vowed to pursue a “people’s veto,” or a public referendum, in which Maine voters could overturn the law. "

Markets for hair, blood plasma, and eggs
A recession report from the Detroit News is headlined Michiganians mine bodies for cash to make ends meet. It reports on a number of legal ways you can monetize your body.
You can sell your hair on TheHairTrader.com, and it looks like some sales have been in the $2,000 range.
You can sell blood plasma at $50 a shot, apparently as often as once a week, judging from the seller interviewed in the story. Here's a site called bloodbanker.com on which you can search for a clinic near you.
If you are young and female you can donate eggs to help couples with fertility problems. Perhaps the lingering repugnance of selling eggs is reflected by the first of these two pricing notes.
Conceiveabilities.com states on their web site that
"ConceiveAbilities strictly adheres to the guidelines as established by the American Society for Reproductive Medicine (asrm.org) which state egg donor compensation more than $10,000 is unethical. Simply stated, a reputable agency will adhere to the guidelines and those that don’t should be viewed with extreme skepticism. "
Egg.donor.com states
"What fees are paid to the Donor?An Egg Donor's fee can range from $5,000 to $15,000. Exceptional and repeat Donors will often receive higher compensation. "

NYC school choice; various updates
The NYC high school choice process (for schools at all levels) is entering its late stages. On the high school front, although the large majority of students are matched to high schools they ranked highly on their preference lists, in a system the size of NYC (with approx 90,000 new high school students each year), there are many students who are not well matched (and for whom the upcoming appeals process may provide some relief).
The Daily News has a story featuring several such students: Education Department fails to place thousands of students in any high school on their list of picksRead more: Education Department fails to place thousands of students in any high school on their list of picks.
"Education Department spokesman Andrew Jacob said the percentage of eighth-graders who went unmatched has improved to 9% from 16% in 2004, when choice was implemented.
The number of students who got their first choice has improved to 51% from 34% since the same year, Jacob added.
"We want all of the 86,000 students who applied for high school to be able to attend a school that's right for them," he said. "Any student who's unhappy at the end of the second round can appeal it."
The problem is that the system is stretched to capacity, so that schools with excess capacity are those which are undesirable in some respects. The things that market designers know about the difficult problems of school choice don't fix this underlying problem of resources.
The NYCDOE provides a bit of information on the different kinds of high schools here, a very brief description of the admissions process here, and information about each high school here.
There are also brief descriptions of the very different, still decentralized processes for pre-kindergaten, elementary schools, and middle schools.

Waiting lists for public school kindergartens, in NYC and in England
If being on a college's waiting list is nerve wracking, having your child on a public kindergarten waitlist is positively infuriating: Kindergarten Waiting Lists Put Manhattan Parents on Edge
"The Department of Education would not say how many schools had waiting lists or how many children were on them, explaining that officials were still reviewing the information that principals in Manhattan were required to submit earlier this week (principals in other boroughs must do so by Friday). But parent advocates and public officials in pockets throughout the city said in interviews that they had heard more complaints this year than ever from panicked parents who were told that there may not be seats for their 5-year-olds at their neighborhood schools.
The notion of a waiting list for students living within a school’s zone is not unprecedented in New York; last fall, 34 schools outside Manhattan capped their enrollment, turning away neighborhood children. But this year, after a change in city policy to standardize kindergarten admissions and encourage registration earlier in the year, the waiting lists seem to have proliferated, making their way into Manhattan neighborhoods where parents often make expensive real estate decisions with a specific school in mind.
David Cantor, the chancellor’s press secretary, said that schools previously had grappled with supply and demand in an ad-hoc way, and that the Bloomberg administration’s approach was more fair. Children who are still on waiting lists at the end of June will be offered slots at other schools in their district (there are 32 across the city), and parents can keep their children’s names on the lists through the summer in hopes that spots open up. City officials expect lists to shrink as some students choose gifted and talented programs, whose placements are to be completed in mid-June, or other options.
Before, Mr. Cantor said, “students remained on wait lists without a school unless a parent knew how to navigate the system.”
“This administration’s position is that equity of access and transparency for every parent is essential,” he added. “This year, for the first time, we stepped in to quantify wait lists, assist schools in managing their wait lists, and will ensure that children have a placement offer by the end of June.”
Something similar is happening in England. The Telegraph reports Thousands of children face being denied a place at their local primary school this year following a sharp rise in demand caused by the recession and increased birth rates:
"Competition is so intense that many families will have to accept their second, third or even fourth choice school, possibly several miles from home. Some four and five year-olds could be left without any place for September. Almost a third of councils across England surveyed by The Daily Telegraph were struggling to cope with demand, with many forced to create more places by building temporary classrooms.
The problem has been blamed on rising birth rates coupled with the economic downturn, which has forced some parents to abandon fee-paying schools for state education."
...
"In Bristol, about 300 children were left without a place at any of their preferred primary schools when the first round of offers was made in February, although most have now been found a school."

Waiting lists from the colleges' point of view
May 1 was the deadline by which students admitted to colleges were supposed to send in their acceptances, so, later this week, when all the mail is in, colleges will finally be in a position to see how many students they might like to admit from their waiting lists.
Unlike rejection letters, which break off a relationship, letters informing candidates that they are waitlisted are meant to influence future behavior. One important goal of the waiting list letter is to encourage those who are most likely to attend if given a (late) offer to signal their willingness in a way that might reliably identify those who will accept an offer from the waiting list if one is offered. That way, if the college has to hurry to fill its places from its waiting list, it can make offers to those most likely to come.
Rice University's FAQ about their waiting list is interesting both for what it reveals and what it conceals:
"What is an "alternate?" What is the "waiting list?"
Your application received strong enough support from the Admission Committee to be approved for admission. However, Rice's small size (only 850 new students) prevents us from admitting all such students. As an “alternate” to the class you are given the opportunity to be placed on the “waiting list.” Students on the waiting list are considered for positions in the class that remain unfilled in May and June.
How many students are on the waiting list?
No one knows yet. Only students who respond affirmatively by May 1, 2009 will be on the waiting list. Not all of the students offered this opportunity will choose to remain an alternate, so the actual size of the waiting list will not be known until May.
How many offers will be made to wait-listed students?
The number of available spaces cannot be determined until after all admitted students respond to our offer of admission by May 1. If fewer than 850 students accept our offer of admission by that date, we will make offers from the waiting list to fill the class in May or June. Over the last four years, 174 students have been admitted from the wait list.
Is the waiting list rank-ordered?
No. All wait-listed students will be reviewed for all available spaces.
Is it appropriate for me to accept an offer of admission from another school while I wait to hear from Rice? What about other waiting lists?
Yes. All schools expect students to commit to one (and only one) school by May 1. However, students may remain on any school’s waiting list throughout the summer. The only rule is that you must withdraw your admission deposit from a school once you accept another school’s offer – you may commit to only one school at a time.
If admitted from the waiting list, how will I be notified?
Students admitted from the waiting list are contacted by telephone. Be sure we have the home phone number and cell phone number (if available) where you can be reached throughout the months of May and June. If you are planning a trip away from home, send a contact number where you can be reached to riceapps@rice.edu.
...
What can I do to increase my chances of admission?
You should update your file in writing via mail or email, informing us of your interest in Rice or spring term accomplishments.
...
It is our goal to send an update to all wait-listed students by June 1, 2009. The waitlist process will be concluded by July 1."
Update (5/8/09): A Crimson story has some information on Harvard's waitlist plans: Yield Holds Steady For 2013 :
"The first round of waitlist deliberations will run from today until the 19th. Fitzsimmons said that “at least 85 if not more” will be taken off the list in the coming weeks, as the office is still waiting to hear from some admitted students. The admissions office aims to have all decisions out by July 1, Fitzsimmons said. He added that it is possible that students admitted off the waitlist will begin hearing as early as today, but more should find out by the middle of next week. The number of students admitted from the waitlist will depend in part on the number of students who choose to defer their offers of admission for a year. So far, 31 students have elected to defer, a number that the admissions office expects to rise. This number is usually between 30-50 students and does not seem to be affected by any particular variable, Fitzsimmons said, though he added it was possible that the bad economy could cause fewer people to defer this year. "
Unlike rejection letters, which break off a relationship, letters informing candidates that they are waitlisted are meant to influence future behavior. One important goal of the waiting list letter is to encourage those who are most likely to attend if given a (late) offer to signal their willingness in a way that might reliably identify those who will accept an offer from the waiting list if one is offered. That way, if the college has to hurry to fill its places from its waiting list, it can make offers to those most likely to come.
Rice University's FAQ about their waiting list is interesting both for what it reveals and what it conceals:
"What is an "alternate?" What is the "waiting list?"
Your application received strong enough support from the Admission Committee to be approved for admission. However, Rice's small size (only 850 new students) prevents us from admitting all such students. As an “alternate” to the class you are given the opportunity to be placed on the “waiting list.” Students on the waiting list are considered for positions in the class that remain unfilled in May and June.
How many students are on the waiting list?
No one knows yet. Only students who respond affirmatively by May 1, 2009 will be on the waiting list. Not all of the students offered this opportunity will choose to remain an alternate, so the actual size of the waiting list will not be known until May.
How many offers will be made to wait-listed students?
The number of available spaces cannot be determined until after all admitted students respond to our offer of admission by May 1. If fewer than 850 students accept our offer of admission by that date, we will make offers from the waiting list to fill the class in May or June. Over the last four years, 174 students have been admitted from the wait list.
Is the waiting list rank-ordered?
No. All wait-listed students will be reviewed for all available spaces.
Is it appropriate for me to accept an offer of admission from another school while I wait to hear from Rice? What about other waiting lists?
Yes. All schools expect students to commit to one (and only one) school by May 1. However, students may remain on any school’s waiting list throughout the summer. The only rule is that you must withdraw your admission deposit from a school once you accept another school’s offer – you may commit to only one school at a time.
If admitted from the waiting list, how will I be notified?
Students admitted from the waiting list are contacted by telephone. Be sure we have the home phone number and cell phone number (if available) where you can be reached throughout the months of May and June. If you are planning a trip away from home, send a contact number where you can be reached to riceapps@rice.edu.
...
What can I do to increase my chances of admission?
You should update your file in writing via mail or email, informing us of your interest in Rice or spring term accomplishments.
...
It is our goal to send an update to all wait-listed students by June 1, 2009. The waitlist process will be concluded by July 1."

Same sex marriage in Canaan
I've posted several times about recent developments in the U.S. on the legalization of gay marriage, most recently here: Same sex marriage in Iowa, and New England . These developments involve the legality of a contract between two willing adults that third parties may find repugnant. This repugnance is of ancient origin, as I was reminded by the Torah portion read yesterday, which includes Chapter 18 verse 22 of Leviticus, which forbids (a male) lying with a male. This comes immediately after the prohibition against handing over your children "to Moloch" (which is often read as a ban on human sacrifice), and after the prohibitions against any kind of incest.
At the blog PaleoJudaica.com there's a discussion of some of the rabbinic discussion about this verse, and one of the comments points to a midrash claiming that the ancient Canaanites, who preceded Israel in the land, used to practice same sex marriage:
"The reference is to the Sifra 8:8, on Leviticus 18:2ומה היו עושים? האיש נושא לאיש והאשה לאשה, האיש נושא אשה ובתה, והאשה ניסת לשנים. לכך אמר ובחוקותיהם לא תלכוThe Hebrew can be translated as, "And what did they used to do? A man married a man and a woman a woman, a man married a woman and her daughter, and a woman married two men. Therefore it says, By their rules you shall not walk." "
So, some transactions have a very long history indeed of being regarded as repugnant. And still, views can change.

Market for sabbatical homes
Professors and some other kinds of teachers have periodic leaves, for a semester or an academic year, that don't match well with the usual rental real estate market, in which leases tend to be for a calendar year. This opens up a niche for a specialized rental market for sabbatical homes.
A professor with an upcoming leave might look to such a market both to rent his or her own home while on leave, and to rent a home where he will be spending his leave. Since other professors are the people most likely to want to rent (in either direction) for a corresponding time period, this opens up the possibility of a dedicated marketplace in which participants in this small slice of the large real estate market can efficiently find each other. (Such a marketplace may also serve to thicken the market for people with taste for the kinds of homes that professors live in, and may make it easier for owners to verify details about potential renters that make them more comfortable to temporarily rent their homes.)
When I searched on the web (under "sabbatical homes"), I found the following contenders for a share of this market, all of which appear to operate as simple listing services (i.e. they post ads, and people can then contact each other).

Update (on the market for goat rentals, as a lawn mowing substitute): This post elicited the following email from Mary O'Keeffe:
"Your post on the sabbatical rental market brought back memories of a year my husband and I spent a couple terms as visiting assistant professors at Caltech in 1981 and rented an incredibly nice luxury Pasadena townhouse from a senior professor who was on leave during the same two terms that year. We got a great below-market price and he got responsible tenants whose schedules aligned with his needs.
Anyway, I thought you might be interested in this article about the developing goat rental market in Silicon Valley:

Football bowls: market design by Congress?
Sports fans will no doubt be relieved to learn that the Feds are on the case: Congress examining fairness, financing of BCS system .
"Tackling an issue sure to rouse sports fans, lawmakers pressed college football officials Friday on switching the Bowl Championship Series to a playoff, with one Texas Republican calling the current system as unworkable as communism and joking it should be labeled "BS," not "BCS."
John Swofford, the coordinator of the BCS, rejected the idea of switching to a playoff, arguing it would threaten the existence of celebrated bowl games. Sponsorships and TV revenue that now go to bowl games would instead be spent on playoff games, "meaning that it will be very difficult for any bowl, including the current BCS bowls, which are among the oldest and most established in the game's history, to survive," Swofford said.
Rep. Joe Barton of Texas, who has introduced legislation that would prevent the NCAA from labeling a game a national championship unless it's the outcome of a playoff system, said that efforts to tinker with the BCS were bound to fail.
"It's like communism," he said at the House Energy and Commerce Committee's commerce, trade and consumer protection subcommittee hearing. "You can't fix it." "
While the BCS system is already a kind of camel (i.e. a horse designed by a committee), it is a considerable improvement over the unraveled market that came before it, in which bowl matchups were frequently mis-matches arranged several weeks before the end of the regular season, see
Frechette, Guillaume, Alvin E. Roth, and M. Utku Unver, "Unraveling Yields Inefficient Matchings: Evidence from Post-Season College Football Bowls," Rand Journal of Economics, 38, 4, Winter 2007, 967-982, with an online appendix).
I'm skeptical that Congress will push this very far, but it is good to know that the country is in such good shape that some of our Congress persons can devote their efforts to this.

College letters of rejection
Today is the day by which students must accept an offer of admission from most colleges. So it's a good time to think about those applications that were not accepted. The WSJ has a story reviewing (in the sense of a book review) the variety of ways colleges convey rejections: Rejection: Some Colleges Do It Better Than Others
"Toughest: Bates College, Lewiston, Maine. Most rejection letters, in an effort to soften the blow, follow a pattern: We're sorry, we had a huge applicant pool, all our applicants were terrific, we wish we could admit everyone. Bates, a competitive, 1,700-student college, expresses its regrets to rejected applicants and praises its applicant pool. But it delivers a more direct, and perhaps more honest, message: "The deans were obliged to select from among candidates who clearly could do sound work at Bates," the letter says."
"Stanford University sends a steely "don't call us" message embedded in its otherwise gentle rejection letter. In addition to asserting that "we are humbled by your talents and achievements" and assuring the applicant that he or she is "a fine student," the letter says, "we are not able to consider appeals." It links to a Q&A that reiterates: "Admission decisions are final and there is absolutely no appeal process." It also discourages attempts to transfer later, an even more competitive process."
"Kindest: Harvard College. Despite an estimated admission rate of about 7% this year, this hotly sought-after school sends a humble rejection letter.
"Past experience suggests that the particular college a student attends is far less important than what the student does to develop his or her strengths and talents over the next four years." "
"Most Discouraging: Boston University. To students who have family ties to the university, its letter begins: "We give special attention to applicants whose families have a tradition of study at Boston University. We have extended this consideration in the evaluation of your application, but I regret to inform you that we are unable to offer you admission."
"Biggest Spin: Numerous colleges spin the data in their rejection letters as a well-intentioned way of comforting denied students. University of California, Davis, says it had "42,000 applicants from which UC Davis could enroll a freshman class of 4,600." This implies an 11% acceptance rate. Its actual admission rate is closer to 50%, because many accepted candidates ultimately enroll elsewhere."

Cadavers for dissection by medical students
I've written before about how the purchase of cadavers (even) by medical schools for anatomy classes was for many years a repugnant and largely an illegal transaction in Europe and the U.S., but no longer. A recent review of a book of photographs of medical students posed with cadavers reveals something about the changing cultural attitudes that have accompanied this shift. Shifts of these kinds are potentially interesting to economists because of what they might tell us about changes in which transactions are regarded as repugnant more generally.
Recent news stories have covered the practice in Asia of having students treat the cadavers as honored teachers, sometimes at ceremonies attended by the families of the deceased: Taiwanese Med Students Honor Cadaver Donors.
"A Taiwanese medical school is responding to the island nation’s shortage of cadavers for study by bringing the family of the deceased fully into the program, the Wall Street Journal reports. At Tzu Chi University, medical students meet with donors' families and even compose poems to their “silent mentors” to express their gratitude. And before they wield their scalpels, they participate in a farewell ceremony."
It turns out such ceremonies have a reasonably long history. From the English language abstract of an article in a Chinese medical journal, Anatomy cadaver ceremonies in Taiwan:
"The practice of holding annual ceremonies in honor of cadaver donors in Taiwan's medical schools has a history of nearly a hundred years. It originated in Japan, where such ceremonies have been widely held in medical schools since the practice was founded by Toyo Yamawaki, who was the first medical scholar in Japan to engage in dissection of the human body and was the author of the first anatomy book to appear in Japan, the Zoshi. The practice of holding donor ceremonies was introduced into Taiwan after the Jaiwu Sino - Japanese war, when the island became a Japanese colony. The tradition was upheld in the Viceroy's Medical School, the Viceroy's College of Medicine, and Taihoku (Taipei) Imperial University College of Medicine, and continued since the restoration of Chinese power to the present. The practice of holding cadaver donor ceremonies in institutions of medical education is intended to express respect for the donor as well as to encourage the practice of cadaver donation to the benefit of medical education."
But going further back in time, it sounds as if the Asian experience may have been quite similar to the European history regarding cadavers. Here is the English abstract of an article published in Japanese on the History of collecting cadavers in Japan
"This study investigated how and from where medical students had acquired cadavers for research throughout Japanese history. At the beginning of dissection in the mid Edo era, they cut up executed prisoners granted by the Tokugawa Shyogunate to study internal body parts. After the Meiji Restoration, the social mechanism of delivering cadavers underwent a complete transformation and they began to utilize 1) dead bodies of inpatients who had received free medical treatment and 2) unclaimed bodies mainly from homes for the aged and prisons. It was quite recently that "kentai", voluntary body donation, became common practice of collecting cadavers. Consequently the history of cadavers submitted to dissection faithfully reflects the relation between medical science and society."
I can't help being reminded of the current cautious attempts in the U.S. to encourage organ donation for transplantation, about which I blogged yesterday: Tax credits for organ donors, and medals.

Tax credits for organ donors, and medals
The issue of what compensation or reimbursement if any to allow for organ donation continues to be raised, very slowly, cautiously, and modestly in American legislation. The latest attempt, in the current (111th) Congress: Living Organ Donor Tax Credit Act of 2009 (Introduced in House), proposes
"In General- In the case of an individual who donates a qualified life-saving organ of such individual for transplantation into another individual during the taxable year, there shall be allowed as a credit against the tax imposed by this chapter for the taxable year the sum of--
`(1) unreimbursed costs paid by the taxpayer in connection with such transplantation, and
`(2) any lost wages of the individual in connection with such transplantation.
`(b) Limitation- The credit allowed under subsection (a) with respect to any individual for any taxable year shall not exceed $5,000."
If this sounds excessively cautious, note that the previous (110th) Congress passed, and on October 14, 2008, President George W. Bush signed into law, the Stephanie Tubbs-Jones Congressional Gift of Life Medal Act (HR 7198) (Public Law No: 110-413). (It was passed without opposition in both houses of Congress). The Congressional Research Service summary of the law reads (emphasis added)
"10/14/2008--Public Law.
(This measure has not been amended since it was introduced. The summary of that version is repeated here.)
Stephanie Tubbs Jones Gift of Life Medal Act of 2008 - Makes any organ donor, or the family of any organ donor, eligible for a Stephanie Tubbs Jones Gift of Life Medal.
Requires the Secretary of Health and Human Services to direct the Organ Procurement and Transplantation Network to establish an application procedure, determine eligibility, and arrange for the presentation of medals.
Allows only one medal per family. Requires that such medal be presented to the donor or, in the case of a deceased donor, the family member who signed the consent form authorizing the organ donation.
Authorizes the Network to collect funds to offset expenditures relating to the issuance of medals.
Prohibits federal funds from being used to carry out this Act. "

Private sales of artworks, in a down market
Auctions are good for price discovery, and price discovery is particularly important for "common value" goods, i.e. goods whose value to each buyer may be substantially influenced by what other buyers are willing to pay. So, what should you do if you want to unload a common value asset but want to avoid disseminating potentially bad news about what it might be worth? The NY Times reports More Artworks Sell in Private in Slowdown .
"During good times, an auction is the obvious choice for any collector wanting to sell a work of art. But as the recession takes its toll, many collectors have changed strategies and retreated to the more hidden, and potentially less lucrative, world of private sales.
"For many sellers, the driving factor is fear. Fear that their friends will discover they need money. Fear that if a Picasso or Warhol, Monet or Modigliani does not sell at auction, it will be considered yesterday’s goods.
If they do not have to, fewer collectors are putting their holdings up for auction at Sotheby’s and Christie’s, where prices and profits have plummeted. But executives at both houses say business in their private-sale departments has more than doubled in recent months. "
...
" “The game has definitely shifted,” said Christopher Eykyn, a former head of Impressionist and modern art at Christie’s who is now a dealer in New York. “A lot of clients don’t want to be seen selling, so the private route is suddenly more attractive.” "
...
"There are exceptions, of course. Estates continue to go to auction because executors have a fiduciary responsibility and prices are rarely challenged after public sales.
For the auction houses, private sales are lucrative and inexpensive. Generally Sotheby’s and Christie’s charge 5 to 10 percent of the purchase price of an artwork, depending on its value and the agreement with the seller. (If a work goes to auction the houses charge sellers 25 percent of the first $50,000, 20 percent of the next $50,000 to $1 million and 12 percent of the rest.) Money earned from private transactions comes cheap, without expenses like advertising, insurance and shipping associated with auctions.
The dismal sales in New York in November, when night after night paintings by Monet and Matisse, Bacon and Warhol went unsold, meant big losses for Sotheby’s and Christie’s, which had a financial interest in most of this expensive art in the form of guarantees, undisclosed sums paid to sellers regardless of a sale’s outcome.
After the fall auctions, both houses immediately began changing the way they conduct business. In addition to announcing hundreds of layoffs, with perhaps more to come, they mostly halted the practice of guarantees and stopped giving consignors a cut in the fees they charge buyers. The days of publishing luscious catalogs have ended as well.
For their part, dealers say that their phones started ringing after Sept. 15, the day Lehman Brothers filed for bankruptcy. “It’s been pretty steady ever since,” said Steven P. Henry, director of the Paula Cooper Gallery in Chelsea. He said he had been getting inquiries about selling art from people who had investments with Bernard L. Madoff, or who had seen the value of their stock or real estate assets collapse."

Rankings of universities: vintages and coordination of expectations
US News and World Report has published its annual ranking of American universities. One thing that the rankings make clear is that, while they may move around a bit from year to year (and the precise rankings are not so informative), it takes a long time to rise to the top.
This year the first place goes to the oldest American university, founded in 1636, and spots 2 and 3 go to universities established in 1746 (as the College of New Jersey), and 1701. Two universities that opened more than a century later, in 1861, and 1891 , are tied for 4th place. The two universities tied for 6th are of different vintages, 1891 and 1755, as are the three tied for 8th place, 1754, 1838, and 1892. The top dozen ranks are filled out by universities open for business since 1769, 1855, and 1856.
At number 17, Rice University, opened in 1912, seems to be the highest ranked university on the list to have begun in the 20th century.
So, while ranking is far from perfectly correlated with age (which is in turn correlated with wealth, among other things), a university that wants to rise to the top of these rankings must take a long view.
It would be good to know more about how rankings (and changes in rankings, especially changes of more than a few places) influence the success of universities in attracting students and faculty. Compared to fundamentals, the rankings themselves shouldn't do much (although they are correlated with features that make a university a desirable place to study and teach). But rankings may also serve as a coordination device for students. For example, if two otherwise similar universities have substantially different rankings, e.g. one is listed in the top 20 and the other in the top thirty, it may be that over time the top 20 university will attract better students, and become a better university. If so, universities that concern themselves with signaling their quality by trying to raise their ranking may not be misguided.
Rankings of international universities (for which the precise rankings are even harder to interpret as being deeply informative) reveal that age is less well correlated with ranking than might appear from looking at American universities alone. For example, in this ranking and in this one, Oxford and Cambridge Universities, both so old that no reliable founding dates are known (although 1096 and 1226 are mentioned in their histories) are both in the top 10. But the much younger American universities dominate the top of the lists, where the equally old universities in continental Europe are scarce.
Update: Here's a November 2009 article from across the pond, which suggests that independence of universities from government may play a role: The American lesson: How to be top

Market for bogus colleges
Colleges not only educate students, they also give them credentials and certifications. So it is not too surprising that there is both a demand for credentials without education, and a supply.
In the United States, the focus seems to be on degrees. (If you type "college degrees" into Google, you find a number of intriguing options, including one that offers a degree in a week. Of course, maybe they have discovered a teaching and learning technology that we should all emulate...)
In Britain, it appears that the market focuses on obtaining a letter of admission, for immigration purposes: Fake colleges enable foreigners to disappear through the loophole.
"Bogus colleges set up to help foreign workers to enter Britain illegally have long been considered the biggest loophole in British immigration controls.
Often little more than two rooms over a takeaway restaurant or newsagents, the colleges have been enrolling hundreds of “overseas students” each year to enable them to obtain visas.
Phil Woolas, the Immigration Minister, described the bogus colleges last month as the Achilles’ heel in the immigration system. The Government announced a crackdown on them in 2003 but regulations did not come into force until the end of last month.
Under the new rules, all universities, colleges and schools must be approved by the UK Border Agency before they can issue visa letters to foreign students. Of the 2,100 institutions that applied for a sponsor licence, 467 have failed the vetting. More than 3,000 other colleges estimated to have been accepting foreign students have not applied for a licence."
One of the latest terrorist suspects to be arrested in Britain appears to have entered Britain from Pakistan with a visa from a bogus college: Terror suspect was enrolled at college shut down by Home Office
Update: a subsequent story, 5/21/09 Sham colleges open doors to Pakistani terror suspects
