The regulated market for cemeteries
The NY Times reports, City Cemeteries Face Gridlock.
"More than 50 years have passed since a major cemetery was established within the city, and no new burial grounds are planned. But New Yorkers continue to die, some 60,000 a year.
"Accordingly, per square foot, burial plots in centrally located cemeteries rival the most expensive real estate in the city. A private mausoleum at Woodlawn Cemetery in the Bronx can easily cost more than $1,000 per square foot.
"“We have people who would like to disinter Mom and Dad and sell the graves back to make some money,” said Richard Fishman, the director of the New York State Division of Cemeteries.
"There are state laws limiting the profits on resold graves, but the fact that people would be willing to go to such lengths, Mr. Fishman said, illustrates just how valuable burial plots have become."
...
"Other major urban areas have taken measures to alleviate similar space crunches. London allows people to be buried upright, while cemeteries in Singapore and Sydney, among others, offer “limited tenure,” cemetery-speak for digging up bodies after a certain amount of time so that the plot can be reused."
...
"It might seem that an enterprising developer could find a way to make a lucrative business out of providing burial space.
"But that has not happened.
"First, by law, cemeteries in New York State must be nonprofit institutions. There are 35 privately owned cemeteries in the city and several dozen with religious affiliations. The closer to Manhattan and major transportation, the more crowded and expensive a burial ground will be. Farther away, particularly in Staten Island and parts of the Bronx, space is available. The indigent of New York City are buried on Hart Island in Long Island Sound.
"Woodlawn, which was part of Westchester County when it was founded in 1863 but was later incorporated into the Bronx, still has burial room. It hopes to be able to offer graves for another 40 to 50 years, but that relative abundance hasn’t kept its prices down.
“We want to have enough saved so that the income from the trust, once we are closed and have nothing left to sell, is enough to maintain the cemetery,” said John P. Toale Jr., the president of Woodlawn.
"While there is a space crunch in the city, there is more space in the suburbs, and cemeteries in upstate New York can barely give away plots, state officials said. Many New Yorkers who struggled and saved to live in the city end up buried elsewhere.
"Even as the broader real estate market languished in the recession, prices for graves in the city continued skyward. The state regulates the fees a cemetery can charge for services like excavation, but graves sell at market price. So burial plots are a cemetery’s revenue-generator.
...
"Now that an end to plot sales is in sight, Green-Wood is seeking to transform its image, according to Richard J. Moylan, its president. The graveyard charges admission for guided tours, giving people a chance to saunter through time among the tombstones of the notable and the notorious. The hope is that it will become much like Père Lachaise cemetery in Paris, a magnet for tourists."

Intellectual property as trade secrets
How are English muffins baked? It's a trade secret, and one surrounded with hints of espionage: A Man With Muffin Secrets, but No Job With Them.
"The company that owns the Thomas’ brand says that only seven people know how the muffins get their trademark tracery of air pockets — marketed as nooks and crannies — and it has gone to court to keep a tight lid on the secret.
That leaves one of the seven, Chris Botticella, out of a job — and at the center of a corporate spectacle involving top-secret recipe files, allegations of clandestine computer downloads and an extreme claim of culinary disloyalty: dumping English muffins for Twinkies and Ho Hos.
Mr. Botticella, 56, delved into the mystery of Thomas’ muffinhood (hint: it has nothing to do with the fork), after Bimbo Bakeries USA bought the brand early last year. At the time, Mr. Botticella was a Bimbo vice president in charge of bakery operations in California.
But he left the company in January, apparently allowing co-workers to believe he was retiring. But he had accepted a job with the rival baker Hostess Brands, which years ago had tried to crack the muffin code.
Bimbo obtained a federal court order barring the move, and late last month an appeals panel in Pennsylvania upheld the order."
...
"Neither Mr. Botticella nor a Bimbo spokesman would comment for this article, but the legal papers in the case suggest a muffin culture more reminiscent of Langley than Drury Lane. Recipe manuals are called code books. Valuable information is compartmentalized to keep it from leaking out. Corporate officials speak of sharing information on a “need-to-know basis.”
According to Bimbo’s filings, the secret of the nooks and crannies was split into several pieces to make it more secure, and to protect the approximately $500 million in yearly muffin sales. They included the basic recipe, the moisture level of the muffin mixture, the equipment used and the way the product was baked. While many Bimbo employees may have known one or more pieces of the puzzle, only seven knew every step.
“Most employees possess information only directly relevant to their assigned task,” Daniel P. Babin, a Bimbo senior vice president, said in a written court declaration, “and very few employees, such as Botticella, possess all of the knowledge necessary to produce a finished product.” "

Medical resident training regulations
Dr. Pauline Chen, writing in the NY Times, describes the new regulations about the training of medical residents: Someone to Watch Over Me
She worries that, with the new emphasis on making sure resident physicians aren't awake too many consecutive hours, something valuable might be lost.
And here's a description in the NEJM of The New Recommendations on Duty Hours from the ACGME Task Force

Some politicians love their spouses
Bettina Klaus points me to the following cheerful story: Germany's opposition leader breaks from politics to donate kidney to wife: Frank-Walter Steinmeier prepares for operation to save life of his partner of 20 years
Interdisciplinary research
Practical market design is almost by definition an interdisciplinary activity, and fortunately Economics as an academic discipline revels in its interactions with other disciplines such as psychology, computer science, and neuroscience. Debate also breaks out periodically about the value of such work, and how to conduct it, or to assess it, or incorporate it.
So I find it very interesting (both as a market designer and an experimental economist) to follow the debate going on among philosophers about their field's so far tentative foray into "experimental philosophy." This debate recently surfaced in several short pieces in the New York Times "Room for Debate" blog.
Joshua Knobe, one of the young X-Phi pioneers, writes that experimental philosophy is A Return to Tradition:
"Traditionally, no one worried very much about the distinction between philosophy and psychology. Philosophers were just supposed to think, at a very broad and fundamental level, about the nature of the human condition. And, as a matter of course, they were supposed to make use of all the intellectual resources available to them, including psychology, history, literature, and much else besides. ...
"I find it puzzling that people sometimes regard these recent developments as somehow taking things in a radical new direction. A more natural response would be to say that they are taking things back to their old direction, back to the direction of David Hume’s immortal Treatise of Human Nature (1739), with its subtitle, "Being An Attempt to Introduce the Experimental Method of Reasoning Into Moral Subjects."
A contrary view is given by Timothy Williamson: Is It Imitation Psychology?
"The real issue concerns the most effective way for each side to learn from the other. There are philosophy-hating philosophers who would like to replace the traditional methodology of philosophy, with their stress on a combination of abstract reasoning and particular examples, by something more like imitation psychology. Without even properly defining what it is they are attacking, they use experimental results in a selective and unscientific spirit to try to discredit the traditional methodology.
"In other cases experimentalists draw lessons for morality from the results of brain scans in comically naive ways, without realizing how many philosophical assumptions they are uncritically relying on in their inferences -- precisely because they neglect traditional philosophical skills in making distinctions and assessing arguments. The danger is that the publicity such crude work attracts will give a bad name to constructive developments in which experimental results really do cast light on philosophical questions.
"Philosophy has most to contribute to the pursuit of truth by refining its own distinctive methods, not by imitating other disciplines. Philosophers are not needed as amateur experimentalists or writers of pop science. We do more to help through our skill in logic, in imagining new possibilities and questions, in organizing systematic abstract theories, making distinctions and the like. "
Following either of the above links will also connect you to the contributions by Kwame Anthony Appiah, Ernest Sosa, Brian Leiter, and Tim Maudlin.
Those of you who follow the debates about neuroeconomics will recognize the general terrain.

Easing into a national kidney paired donation program
UNOS has a press release on the progress being made towards setting up a national kidney exchange program, headlined Getting it Right: Kidney committee easing into KPD with two-step pilot project
"Some transplant centers throughout the country have been using this method, known as kidney paired donation (KPD), for several years. UNOS has now embarked on a pilot project designed to assess the feasibility of a national kidney paired donation program in which all centers could participate.
"Members of the OPTN/UNOS kidney transplantation committee began discussing the idea of kidney paired donation in 2004. They went as far as proposing a concept they distributed for public comment.
"After receiving positive feedback, the committee distributed a more fully developed proposal in August 2006. Although fleshed out, the proposal was still not ready to go to the OPTN/UNOS board of directors because of concerns about transplant law. As we know, the National Organ Transplant Act (NOTA) prohibits the sale of organs.
"In 2007, Congress definitively clarified that NOTA’s definition of “valuable consideration” did not apply to the organs in a KPD exchange. The law was later titled the Charlie W. Norwood Living Organ Donation Act in honor of the long-time Georgia representative, a lung recipient and sponsor of the bill, who died in February 2007 before the bill became law.
"Around that time, the OPTN/UNOS kidney transplantation committee had issued a request for information from experts in the field. Committee members wanted to know what centers performing KPD were doing, and how they were doing it. The
community responded generously.
"Then, in February 2008, representatives from multiple transplant centers, OPOs, universities and private organizations across the country came to UNOS to share not only their knowledge but also the software they were using for the complex
matching that KPD required.
"Members of the kidney committee wanted to proceed cautiously before taking on the considerable challenge of coordinating a national KPD system. After much deliberation, they determined that the best strategy was a two-phased pilot project" ...

In Egypt, marrying an Israeli is a repugnant transaction
Egyptians Married to Israelis to Lose Citizenship
"CAIRO (AP) -- An Egyptian appeals court on Saturday upheld a ruling that orders the country's Interior Ministry to strip the citizenship from Egyptians married to Israeli women.
"The case underlines the deep animosity many Egyptians still hold toward Israelis, despite a peace treaty signed between the two countries 31 years ago.
"The Supreme Administrative Court's decision also scores a point for Egyptian hard-liners who have long resisted any improvement in ties with Israel since the signing of the 1979 peace treaty.
..."Saturday's decision, which cannot be appealed, comes more than year after a lower court ruled that the Interior Ministry, which deals with citizenship documents, must implement the 1976 article of the citizenship law. That bill revokes citizenship of Egyptians who married Israelis who have served in the army or embrace Zionism as an ideology. The Interior Ministry appealed that ruling.
..."In 2005, former Grand Mufti Nasr Farid Wasel issued a religious edict, or fatwa, saying Muslim Egyptians may not marry Israeli nationals, ''whether Arab, Muslim, or Christian.'' The possibility of a Jewish spouse was not mentioned.
"Mohammed Sayyed Tantawi, the late Grand Sheik of Cairo's Al-Azhar, Sunni Islam's premier institution and oldest university, has said that while marriage between an Egyptian man and an Israeli woman is not religiously forbidden, the government has the right to strip the man of his citizenship for marrying a woman from ''an enemy state.''"

Online real estate markets: Yahoo and Zillow
Yahoo Pairs with Zillow on Real Estate Listings
"The deal also helps Yahoo and Zillow challenge Move Inc. (MOVE), owner of Realtor.com, the most-used real estate site."
...
"Until now, Yahoo has focused mainly on selling ads from large marketers, such as mortgage companies and credit agencies, not the local real estate agents that are Zillow's mainstay, Schultz said. In May, Yahoo was No. 3 in the online real estate market with 6.14 million users, while Zillow.com was second with 7.05 million, according to ComScore (SCOR) of Reston, Va. The market was led by Move Inc., with more than 12 million."

A four-way exchange in basketball
A regular reader alerts me to a four-way exchange in basketball (for all of you who thought those were just for kidney exchange:)
"Wednesday's four-team trade between Houston, Indiana, New Jersey and New Orleans featured the Hornets' young point guard, Darren Collison, going to Indiana, and the Rockets sending forward Trevor Ariza to New Orleans. The Rockets also got guard Courtney Lee from the Nets, while the Nets acquired forward Troy Murphy from Indiana. Indiana took on veteran forward James Posey from New Orleans to complete the deal."

Roommate matching and the social internet
Roommate matching continues to evolve, with Facebook playing a key role: Students Turn to Online Roommate Matching Services to Avoid Getting Paired With a Stranger (HT: Mike Ruberry)
The Chronicle gives a good description: Colleges Use Facebook to Let Freshmen Find Their Own Roommates
"This summer, incoming freshmen at five universities can use a Facebook application to find their roommates. Students can use the application, RoomBug, to fill out forms about their preferences for living and qualities they'd like to see in a roommate. Students can then request a match, which the other incoming freshman must confirm.
RoomBug is hardly the first service to let students match themselves: Tulane University announced a partnership with online service RoommateClick two years ago.
But RoomBug, which the company U-Match LLC just rolled out at Emory University, the University of Florida, Temple University, Wichita State University, and William Paterson University of New Jersey, tries to go where the students are.
"Everyone is on Facebook," says Robert Castellucci, the service's co-founder and sales director.
Over a quarter of the University of Florida's incoming freshmen have added the Facebook application, he says, but numbers on how many matches the service helped make are not yet available."
Maureen Dowd regrets the trend, writing in her NY Times column
"The serendipity of ending up with roommates that you like, despite your differences, or can’t stand, despite your similarities, or grow to like, despite your reservations, is an experience that toughens you up and broadens you out for the rest of life.
"So I was dubious when I read in The Wall Street Journal last week that students are relying more on online roommate matching services to avoid getting paired with strangers or peers with different political views, study habits and messiness quotients."

Pet food
Luke Stein at Stanford points me to Brian Palmer's column in Slate about where it is illegal to eat pets: Is it legal to eat your cat?
"Few states have specific laws barring the use of pets for food. The ones that do typically ban the slaughter or sale of dog and cat meat. The state of New York expressly prohibits "any person to slaughter or butcher domesticated dog (canis familiaris) or domesticated cat (felis catus or domesticus) to create food, meat or meat products for human or animal consumption." It's not clear whether the eating itself is outlawed or only the butchery. If you managed to buy dog or cat flesh from someone else who broke the anti-slaughter law, you might be OK. The law also doesn't cover ferrets, gerbils, parakeets, or other less familiar pet species. (Although the general anti-cruelty law might protect exotics.)
"California's anti-pet-eating law has a broader reach. It bars possession of the carcass, so having bought your cat steaks from someone else wouldn't be a useful alibi. The California law also protects "any animal traditionally or commonly kept as a pet or companion," rather than just Fido and Fluffy. The statute is somewhat untested, though, so no one really knows which animals are included. Pigs are not, even though they are commonly kept as pets, because they are farm animals. Horses are specifically covered by a different section of the code. There's no precedent on iguanas, goldfish, or boa constrictors.
"In most of the country, the legality of pet-eating would come down to the specific language of the general animal cruelty statute and how a judge interpreted it. Some states, such as Virginia, bar the unnecessary killing of an animal, with a specific exemption for "farming activities." In those places, it's very likely that killing a cat for dinner would get you in trouble, because the killing wouldn't be necessary, and cats aren't commonly associated with farming.
...
"Worldwide, cat and dog meat seem to be at a crossroads. China pulled dog meat off the market for the 2008 Beijing Olympics and is considering a law barring it permanently. South Korea, on the other hand, has inched toward explicitly legalizing the widespread and officially tolerated dog-meat trade."
Back in February, Roger Cohen described eating dog in China: Dog Days in China
"Now, we are appalled in the West at the notion of eating dog while considering it natural to have a dog as a pet — I own a Beagle myself (“Ned”) and I’m very fond of him. This is the inverse of the preponderant Western view of pigs: fine to eat (religious objections aside) but not to pet."

And see my earlier post: Why can't you eat horse meat in the U.S.?
This raises the question of why some people are disgusted by the idea of eating horse meat.
Michael Webster points me to the Boston Globe article "Ewwwwwwwww! The surprising moral force of disgust," which reports on a recent conference of psychologists.
"Psychologists like Haidt are leading a wave of research into the so-called moral emotions — not just disgust, but others like anger and compassion — and the role those feelings play in how we form moral codes and apply them in our daily lives. A few, like Haidt, go so far as to claim that all the world’s moral systems can best be characterized not by what their adherents believe, but what emotions they rely on.
"There is deep skepticism in parts of the psychology world about claims like these. And even within the movement there is a lively debate over how much power moral reasoning has — whether our behavior is driven by thinking and reasoning, or whether thinking and reasoning are nothing more than ornate rationalizations of what our emotions ineluctably drive us to do."

Unraveling of law internships in Israel
I recently wrote about the Unraveling of law firm interviews of 2nd year students in the U.S. It turns out that something similar is facing Israeli law students.
Assaf Romm, who just moved from Israel to Boston to study for a Ph.D. at Harvard writes:
"The Israeli market for law interns suffers from congestion. Recent ruling (first published today, see below) is that preliminary interviews could only be scheduled on third year of studies. I have many friends who were law students, and most of them signed a contract around their second year, where the interviews are scheduled around first year. Most of the interviews are conducted around the same period, and the firms are invited to the universities on certain date.
"Another interesting feature which isn't mentioned in the article is that there is also a very deep problem with the coordination between the interviews to public sector internships and private sector internships. Some (but only a very small number) of positions in the public sector are much more prestigious than any in the private section (specifically, the supreme court internships and the "Bagaz" department are considered best). Because of that, firms always make exploding offers before the public sector interviews even begin. A future-intern who decides to reject the firms' offers is usually making a high-stakes bet, because even the best cannot be sure they will get the good public internships, and if they don't get it they have to wait another year to start their internship in the private sector."
"The Hebrew article: http://www.ynet.co.il/articles/0,7340,L-3938299,00.html
"I couldn't find English translation. Here is Google translate (not a very good one, but understandable): http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http://www.ynet.co.il/articles/0,7340,L-3938299,00.html&sl=auto&tl=en "
Update: apparently this is an issue of long standing, Itai Ashlagi sends this story from Haaretz in 2008. Law students to apply for internships only from third year :
Israel Bar Association's council approved the rules governing job offers for internships, though they still require the justice minister's approval.
"In recent years, law students have started arranging a place for doing their articles as soon as they start their studies, said attorney Orrin Persky, the head of the Bar Association's committee on internships. He explained that this pressure emanated from both the students and the law firms and has created a market failure for finding such posts.
"In addition, there are a large number of complaints about students canceling their internship positions, which they had agreed to a year or two earlier.
"The new rules would require firms and all other bodies providing internships, such as the State Attorney's Office, to start interviewing no earlier than March 15 of the student's third year for the internship that will start in the following calendar year. "

"Social" science
A novel kind of crowd-sourcing is described in: In a Video Game, Tackling the Complexities of Protein Folding
"Proteins are essentially biological nanomachines that carry out myriad functions in the body, and biologists have long sought to understand how the long chains of amino acids that make up each protein fold into their specific configurations.
"In May 2008, researchers at the University of Washington made a protein-folding video game called Foldit freely available via the Internet. The game, which was competitive and offered the puzzle-solving qualities of a game like Rubik’s Cube, quickly attracted a dedicated following of thousands of players.
"The success of the Foldit players, the researchers report in the current issue of Nature, shows that nonscientists can collaborate to develop new strategies and algorithms that are distinct from traditional software solutions to the challenge of protein folding.
"The researchers took pains to credit the volunteers who competed at Foldit in the last two years, listing “Foldit players” at the end of the report’s author list and noting that more than 57,000 players “contributed extensively through their feedback and gameplay.” "

The (changing) market for law professors
The New Realities of the Legal Academy by Lawrence B. Solum
"Abstract: This short paper is the Foreword to Brannon P. Denning, Marcia L. McCormick, and Jeffrey M. Lipshaw, Becoming a Law Professor: A Candidate's Guide, American Bar Association, Forthcoming.
"One of the great virtues of Denning, McCormick and Lipshaw’s guide is that it reflects the changing nature and new realities of the legal academy. Not so many years ago, entry into the elite legal academy was mostly a function of two things - credentials and connections. The ideal candidate graduated near the top of the class at a top-five law school, held an important editorial position on law review, clerked for a Supreme Court Justice, and practiced for a few years at an elite firm or government agency in New York or Washington. Credentials like these almost guaranteed a job at a very respectable law school, but the very best jobs went to those with connections - the few who were held in high esteem by the elite network of very successful legal academics and their friends in the bar and on the bench. The not-so-elite legal academy operated by a similar set of rules. Regional law schools were populated by a mix of graduates from elite schools and the top graduates of local schools, clerks of respected local judges, and alumni of elite law firms in the neighborhood. In what we now call the "bad old days," it was very difficult indeed for someone to become a law professor without glowing credentials and the right connections.
"But times have changed. When the Association of American Law School’s created the annual Faculty Recruitment Conference (or FRC) and the associated Faculty Appointments Register (or FAR), the landscape of the legal academy was forever changed. The change was slow in coming. For many years, candidates were selected for interviews at the FRC on the basis of the same old credentials and connections, but at some point (many would say the early 1980s), the rules of the game began to change. In baseball, a similar change is associated with Billy Beane, the manager of the Oakland Athletics, who defied conventional wisdom and built winning teams despite severe financial constraints by relying on statistically reliable predictors of success. The corresponding insight in the legal academy (developed by hiring committees at several law schools) was that the best predictor of success as a legal scholar was a record of publication. It turns out that law school grades, law review offices, and clerkships are at best very rough indicators of scholarly success. But those who successfully publish high quality legal scholarship are likely to continue to do so."
The paper itself is only 3 pages, and the abstract is a good summary...

Matching services for friends?
Robin Hanson asks "Why Not Friend Match?" I.e. why are there dating sites but not friend sites?
That isn't to say that there aren't friend matching sites (e.g. here, and here, not to mention Facebook), but nevertheless his conjecture strikes me as plausible: we (at least initially) draw our friends from the people and places we encounter for other reasons, since friends complement our other activities. Or, as he puts it:
"Since we need friends in substantial part to serve as allies in our social world, supporting us against opposing coalitions, it makes sense to draw our friends from our existing social world. And since we need mates more for their personal quality, e.g., good genes, youth, wealth, smarts, mood, etc., it makes sense to pick them more via such features."

The international market for ironing boards
The Washington Post reports Indiana ironing-board factory faces stiff competition from Chinese companies.
"There is one factory left in the United States that manufactures the basic ironing board, and its survival against Chinese competition demands unrelenting, production-line hustle.
"The 200 people at the plant in this small town make their boards very, very cheaply and as fast as 720 in an hour. In three low-slung buildings without air conditioning, coils of cold-rolled steel are cut, welded, riveted and boxed, then loaded onto the Wal-Mart and Target trucks backed up to the loading dock. Paid with piece-rate incentives, workers emerge weary at shift's end.
"The people on the line are making pretty good money; it can work out to about $15 an hour," said Dave Waskom, 61, a tool and die maker who readied the plant's machinery for 37 years. "But they work like dogs."
"Yet loyalty and hard work are not enough.
The company survives in part because it convinced U.S. trade officials that Chinese firms were unfairly dumping ironing boards into the United States at less than fair-market value; in response, the United States levied anti-dumping taxes of 70 to more than 150 percent on its Chinese rivals."

Another live liver donation tragedy
Live liver donation remains much more dangerous than kidney donation: Donor dies after live liver transplant at CU Hospital
AURORA, Colo. - A man who agreed to donate part of his liver to help save his brother died just four days after the transplant procedure at The University of Colorado Hospital.
"It's the first death of a living liver donor in Colorado and only the fourth in the U.S.
"The death has led to a temporary halt of all live donor liver transplants at The University of Colorado Hospital. The hospital has also launched an investigation into what went wrong.
"It has reported the death to the Colorado Department of Public Health, which is conducting its own investigation.
"Ryan Arnold, 34, of Watertown, South Dakota died on August 2nd, just four days after his brother, Chad, 38, of Castle Rock, received part of his liver. "
There was an earlier death this year.

Suicide and organ donation
Assisted suicide is one of the persistently repugnant transactions, although it is the subject of a good deal of modern debate around the world. Here's a story likely to give you pause to think: Lou Gehrig's victim: Kill me for my organs
"he ... compares his situation to a soldier in a foxhole throwing himself on a grenade to save his comrades.
"I am not suicidal," he says. "I just know that it is a matter of time before I die and wish to do a good thing for those people who have a good life expectancy"

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

Education as a filter--for Supreme Court justices
Yale, Harvard Law Taking Over Supreme Court
"In a new paper, Patrick J. Glen, an adjunct professor at Georgetown University Law Center, researched the legal educations of Supreme Court justices through time and found a curious pattern."
...
"However you categorize Justice Ginsburg’s pedigree, one fact would still be guaranteed by Ms. Kagan’s confirmation: For the first time in history, every sitting Supreme Court justice will have graduated from an Ivy League law school.
Mr. Glen writes, “Kagan will take the place not only of the last remaining Protestant on the Court, but also of its last non-Ivy League hold-out—the Chicago educated Justice John Paul Stevens (Northwestern Law School).”
So in some respects, the court has gotten a little more diverse over the years, with Congress confirming more racial minorities and women. But perhaps that just reflects the changing admissions processes at the nation’s top two law schools."
In this story covering her swearing in, the Times' Peter Baker writes
"Arguably, Justice Kagan made a mark from the moment she took the oaths on Saturday. She is the third woman on the current court, joining Justices Ruth Bader Ginsburg and Sonia Sotomayor. She is also the fifth justice born after World War II, making that group a majority, and she brings down the average age on the court to 64, from nearly 69. And she is the first person since William H. Rehnquist, 38 years ago, to join the court without experience as a judge.
If her installation added diversity in some ways, though, it reinforced the court’s lack of it in other areas. Her addition means the court now includes neither Protestants nor anyone without an Ivy League background. Justice Kagan joins two other Jewish justices and six Catholics. She is the sixth justice to have studied at Harvard Law School (although Justice Ginsburg later transferred to and graduated from Columbia Law School); the other three graduated from Yale Law School. And she is the fourth justice to have grown up in New York City."

Marriage, jobs, and immigration
A recent NBER paper relates two things whose interaction has fascinated me for some time (the marriage and job markets) with a third, immigration.
America's settling down: How Better Jobs and Falling Immigration led to a Rise in Marriage, 1880 – 1930 by Tomas Cvrcek, NBER Working Paper No. 16161, July 2010.
Abstract: The growing education and employment of women are usually cited as crucial forces behind the decline of marriage since 1960. However, both trends were already present between 1900 and 1960, during which time marriage became increasingly widespread. This early period differed from the post-1960 decades due to two factors primarily affecting men, one economic and one demographic. First, men’s improving labor market prospects made them more attractive as marriage partners to women. Second, immigration had a dynamic effect on partner search costs. Its short-run effect was to fragment the marriage market, making it harder to find a partner of one’s preferred ethnic and cultural background. The high search costs led to less marriage and later marriage in the 1890s and 1900s. As immigration declined, the long-run effect was for immigrants and their descendants to gradually integrate with American society. This reduced search costs and increased the marriage rate. The immigration primarily affected the whites’ marriage market which is why the changes in marital behavior are much more pronounced among this group than among blacks."

Brokers for pirate ransom
Suppose your ship were hijacked by Somali pirates, and you wanted to ransom it and the crew. How would you go about it? You would need a middleman, someone who could get the money to the right pirates, and maybe who played a repeated game with them, to help ensure that the release would go as planned. As it happens, you might become the client of a certain kind of British law firm, whose market is now threatened by the imposition of sanctions against those who deal with certain named Somali pirates. The problem is, it may be impossible to pay a ransom without doing business with the embargoed individuals. The Financial Times reports: Somali crackdown threatens City role on ransoms
"International plans for a legal crackdown on the funding of piracy could scupper a burgeoning City industry.
"The United Nations plans for sanctions on two suspected pirates would hit the often lucrative work of the law firms, insurers and private security companies in London that quietly arrange ransoms to free kidnapped ships and crews."
...
"The government has decided to block the UN plans amid worries they could force shipowners and their advisers to stop paying ransoms or else risk prosecution.
"London’s piracy negotiation business brings together an unusual cast of characters, from hard-bitten security operatives to dapper lawyers making telephone calls to hijacked ships from offices close to the banks of the Thames.
"NYA International, a kidnap response specialist based off Bishopsgate and now part of Aon, the US insurance broker, has advised on more than 20 piracy incidents during the past 18 months or so.
"The leading ship hijack case law firm in terms of numbers of clients is said to be Holman Fenwick Willan, which has offices north-west of the Tower of London.
"James Gosling, partner at HFW, said: “Nobody wants to pay ransoms. But when it’s the only option, what the hell else do you do?” "
...
"The concern about sanctions is that, while they do not explicitly outlaw the payment of ransoms, they make it impossible in practice because of the uncertainty about where money given to pirates will end up.

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

New Orleans Receivables Exchange
In several earlier posts I've been following the progress of the New Orleans Receivables Exchange.
The State of Louisiana has now passed some legislation that makes it easier for companies to sell their accounts receivable: here's the text of the Louisiana Exchange Sale of Receivables Act.
And here's an article from Inc. Magazine: A New Liquidity Solution

Korean marriage brokers for foreign brides
After a tragedy involving the death of a young woman, SKorea Cracks Down on Marriage Brokers .
"...Her death in early July has drawn attention to the growing trend of South Korean men looking overseas for brides...
"Over the past decade, a growing number of South Korean men, particularly from farming villages with dwindling populations, have been looking overseas for wives....
"They pay an average of $9,900 to brokers to connect them with young women looking for economic security, mostly from Southeast Asia and China, Heo said.
''International marriages are in a way a practical intersection of interests, bringing together South Korean bachelors and foreign women who suffer from poverty and have a romanticized notion of a prosperous life in an industrialized country like South Korea,'' Heo said.
"In 2009, 180,000 foreigners were married to South Koreans, including more than 35,000 Vietnamese women, the Ministry of Public Administration and Security said.
"Many met their spouses through the estimated 1,250 marriage brokers or matchmakers who arrange an estimated 15,000 marriages each year between South Korean men and foreign women, mostly from Southeast Asia, the Ministry of Gender Equality and Family said. "

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

The market for electricity
As the supply of electricity changes in response to growing numbers of wind turbines, there's more need to be able to store electricity: Wind Drives Growing Use of Batteries
"In New York and California, companies are exploring electrical storage that is big enough to allow for “arbitrage,” or buying power at a low price, such as in the middle of the night, and selling it hours later at a higher price. In the Midwest, a utility is demonstrating storage technology that can go from charge to discharge and back several times a minute, or even within a second, bracing the grid against the vicissitudes of wind and sun and transmission failure. And in Texas, companies are looking at ways of stabilizing voltage through battery storage in places served by just one transmission line."
I also recently heard of attempts to create more flexible demand by fitting households with electrical heat storage units, that heat bricks when electricity is cheap, and power the household heating system off the stored heat.

School choice in Darebin City, Victoria, Australia
It sounds like at least one school district in Australia has less bureaucracy than my colleagues and I have encountered in helping American cities reorganize their school assignment systems. Kwanghui Lim at CoRE Economics reports: Game Theory in Action: Sven Feldmann on Kindergarten Matching.
More on school choice here, and here. (And here is a video of Muriel Niederle presenting a new school choice algorithm to the San Francisco school board meeting that gave the go ahead for a redesign there.)

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

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

More market design in Hebrew
Forbes has an Israeli edition, and here is a Hebrew translation of the article that ran in English here.
(Here's a different market design article in Hebrew, featuring Itai Ashlagi, that I posted about earlier.)
(Here's a different market design article in Hebrew, featuring Itai Ashlagi, that I posted about earlier.)
Repugnance and/or disgust
I like to distinguish what I've called repugnant transactions from those that elicit disgust. By repugnant transactions I mean transactions that some people want to engage in and that others don't want them to (e.g. same sex marriage, or buying or selling a kidney, or ordering horse meat at a U.S. restaurant). One sign that a transaction is viewed as repugnant by a sufficiently big part of the population is if it is illegal. Disgusting transactions most often don't elicit legislation (except in a consumer protection way), e.g. it's illegal in CA to offer to sell horse meat for human consumption, but not, say, spit: the difference being that some people would like to buy and eat horse meat.
However there's no denying that part of what makes some transactions repugnant to some people is that they find them disgusting (see e.g. Martha Nussbaum on same sex marriage). There have been recent reports in the press and blogosphere on attempts to link physiological indicators of disgust to, among other things, political proclivities.
Nicholas Kristof in the NY Times gives a quick overview of some conclusions of this sort: Our Politics May Be All in Our Head
Mark Liberman at Language Log takes a closer look: Physiological politics, and suggests that at least some of the results could be artifacts of the experiment. (He has a followup here: Icktheology.)
In the context of organ transplantation, I've noted that the repugnance to sales of organs is hard to equate with a visceral disgust reaction, since there isn't repugnance to transplants in general. There may of course be specific exceptions to that, see e.g. this article in the American Journal of Transplantation:

The market for once-used wedding dresses
For Sale: One White Dress, Yet to Be Worn
"AS more brides try to sell their used wedding dresses online, some have found a way to stand out from the competition: putting their gowns up for sale before even walking down the aisle.
A growing number of postings for so-called presale dresses have popped up among the listings on sites like oncewed.com, preownedweddingdresses.com and woreitonce.com.
...
"A used dress generally sells for about 50 percent off retail, whether sold before or after the wedding. But brides see an advantage to selling before the wedding because the styles are still current and other brides often can try on the same dress in stores. That, they say, enhances the likelihood of a quick sale.
...
"Zofia Gajdamowicz, 27, a bartender in Toronto who hopes to sell her Modern Trousseau dress before her wedding in late October, said she will “have to be a little more careful” if she finds a buyer.
“I already told my friends, ‘Don’t let me drink any red wine,’ ” she said."

The market for professionally taken digital photographs
I was recently the subject of a magazine story, and, before it was published, the photographer Shawn Henry came to campus to "take my picture". That phrase doesn't do justice to what he actually did, which resulted in 148 photographs, eventually edited down to 30, and then to 5 that were sent to the magazine editors to choose the final one.
Mr Henry has given me permission to link to his copyrighted photos, in case you want to see how this sausage was made: here are the 148 pictures, the 30 pictures, and the final one (this link may take a minute to load, it's to the Forbes article...)
These pictures didn't take a lot of time for him to make; as I recall, we were together for about half an hour. (Even though we were outdoors, he deployed some lights and reflectors.)
Seeing how a pro works has made me feel better both about how I often don't like either how I look in pictures, or how other people look in pictures that I take. Many of the pictures linked above were not so flattering (particularly in the set of 148), but I liked the final one. So selection from a wide variety helps. (And now I just need to lose a little weight:)
Modern electronics have probably changed not only the equipment that photographers use, but also how they work.

The market for boasting
How did people boast signal before they had blogs?
Not long ago I was the subject of a flattering profile in Forbes (which I wrote about in this earlier blogboast post).
Yesterday I received a letter in the mail from a company that "specializes in turning articles into custom designed plaques."
It's not a bad idea, and if I were a restaurant, I'd buy one right away, and post it next to the menu, preferably where it could be read from the street.

Kidney transplantation advice from the Netherlands
Two recent reports from the Netherlands give advice drawn from their active transplant program.
The (American) National Guideline Clearinghouse highlights one set of recommendations: Kidney donation. In: Guidelines on renal transplantation. European Association of Urology - Medical Specialty Society. 2009 Mar. 23 pages. NGC:007337 (full text here.)
The first three recommendations under the first category of recommendations, "Ethical Issues in Transplantation," illustrate some of the conflicting forces at work:
- "It is the right of individuals to donate as well as to receive an organ.
- "Commercially motivated renal transplantation is unacceptable. It has been widely prohibited by law and is strongly opposed by the International Society of Transplantation.
- "With the increasing success of living-donor transplants, as judged by graft and patient survival, and with the scarcity of deceased donor organs, living-donor transplants should be encouraged. "
- The altruistic living donor must give informed consent, which can only be obtained if he or she has a proper understanding of the risk involved.
They have this to say about kidney exchange:
- Paired kidney exchange if permitted by national law is a way of increasing the number of kidney transplants..
Another report, focused specifically on kidney exchange is from Clinical Transplants 2009:247-52, "On chain lengths, domino-paired and unbalanced altruistic kidney donations," by de Klerk M, Zuidema WC, Ijzermans JN, Weimar W. Dept of Internal Medicine - Transplantation, Erasmus MC, University Medical Centre Rotterdam, Rotterdam, The Netherlands.
"Abstract: Kidney transplantations with living related and unrelated donors are the optimal option for patients with end-stage renal disease. For patients with a willing--but blood-type or HLA incompatible donor--a living-donor kidney exchange program could be an opportunity. In Asia, the United States and Europe, kidney exchange programs were developed under different conditions, with different exchange algorithms, and with different match results. The easiest way to organize a living-donor kidney exchange program is to enlist national or regional cooperation, initiated by an independent organization that is already responsible for the allocation of deceased donor organs. For logistic reasons, the optimal maximum chain length should be three pairs. To optimize cross-match procedures a central laboratory is recommended. Anonymity between the matched pairs depends on the culture and logistics of the various countries. For incompatible donor-recipient pairs who have been unsuccessful in finding suitable matches in an exchange program, domino-paired kidney transplantations triggered by Good Samaritan donors is the next alternative. To expand transplantations with living donors, we advise integrating such a program into a national exchange program under supervision of an independent allocation authority. If no Good Samaritan donors are available, an unbalanced kidney paired-exchange program with compatible and incompatible pairs is another strategy that merits future development."
PMID: 20524290 [PubMed - in process]
Their conclusion that "the optimal maximal chain length should be three pairs" has certainly not been the U.S. experience: my conjecture is that they are limited to the operating rooms they can organize in a single hospital.
Kidney exchange in Haaretz
Here's an article (in Hebrew) on kidney exchange, featuring the work of Itai Ashlagi. (The article is also here.)
Update: it wasn't in Haaretz itself, but in an accompanying magazine supplement.

Economics and computer science
The links between economics and computer science are growing steadily closer, judging from this report conveyed by Noam Nisan about the Shanghai summer school in algorithmic game theory.
Paul Klemperer's "product mix auction"
Paul Klemperer writes from Oxford:
"the Bank of England has now been running my "product mix auction" for the last two months almost exactly as set out in Section 2 of "The Product-Mix Auction: a New Auction Design for Differentiated Goods" (including "paired bids" etc.)
"Although I designed it for the financial crisis when I was consulted in 2007 after Northern Rock bank run, full implementation was slow. But it is now fully implemented and running regularly (in part, so using it is not seen as a signal of crisis).
"It's perhaps best understood as a "proxy" version of a simultaneous multiple round auction. That is, bidders input their preferences, and the auction chooses the outcome that an SMRA would select assuming straightforward bidding. Because the auction is "sealed bid", it runs instantaneously (important in the Bank's financial-market context), and it therefore also less vulnerable to collusion. Another novel feature is that the auctioneer also bids its preferences about how the proportions of different varieties that it will sell will depend upon the auction prices. (By contrast, SMRA implementations I am aware of specify the number of each type of good to be sold in advance.) It's also related to Paul Milgrom's independently-invented assignment auction, but the way bidders represent their preferences is different (easier and more general in some ways).
"The Bank's specific problem is to auction loans linked to varying qualities of collateral [to inject liquidity into the banking system rapidly], but
--charge different borrowers different interest rates reflecting the different collateral-qualities [to reduce moral hazard];
--allow market conditions, as revealed by the bids, to determine BOTH the interest-rate-premium for inferior collateral AND the proportion of inferior collateral accepted [because the Bank may neither be sufficiently informed about conditions, nor wish to send a 'signal' to the market];
--permit borrowers to specify how the collateral they supply will depend upon the auction outcome [because the interest-rate-premium is not - see above - pre-specified]
"I've advised other Central Banks. Other future applications might include other purchasing "toxic assets", selling electricity, and trading biodiversity."
Peer to peer overnight accommodations
The NY Times reviews sites of "social network bed and breakfasts" on which you can reserve rooms for overnight stays in cities around the world: Europe Without Hotels.
The sites have various ways to protect against scams:
"In Paris, AirBnB has places in every arrondissement, including $13-a-night rooms in the western suburbs and $285-a-night houseboats on the Seine. As the first Web site of its kind to grab the headlines, the system has already developed a large and loyal user base. Some properties have as many as 70 user-generated reviews, which give paying guests a greater sense of confidence. It is similar to how eBay works: you’re more likely to buy from an eBay seller with good feedback." ...
"After the brief tour, I gave Mr. Mostaedi the code that allows him to collect my payment from iStopOver. That’s one of the safeguards that iStopOver offers to guests. If a listing turns out to be fraudulent or misstated, you can refuse to give the owner the code, and the fee is refunded in full. Other services offer similar protections: AirBnB withholds a host’s payment until 24 hours after guests check into an accommodation in order to fend off potential scammers, and Crashpadder uses credit card payments to verify guest identities (though it says it will monitor but not otherwise involve itself in any disputes)."

Unraveling of law firm interviews of 2nd year students
Catherine Rampell has an informative article about The Other Law School Arms Race. The date at which large law firms interview 2nd year law students (for summer associate positions that are the entry path to permanent positions after graduation) has moved earlier, to the summer before the second year begins.
"Speaking of the career paths for new lawyers, we’ve noted before that the sour legal job market has encouraged law schools to find creative ways to make their students look more attractive to employers, at least when compared with students from other schools. Intentional grade inflation is one particularly controversial tool schools have been using.
"But the arms race has found another battlefield as well: on-campus interview week.At most top schools, early in the second year of law school, dozens of law firms visit campus to conduct a round-robin of job interviews with students. These interviews are the first step to a summer associate job after the second year, and oftentimes a permanent job offer after graduation following the third year of school.
"The exact timing of this “on-campus interview week” has traditionally varied by school, and from firm to firm, thereby allowing different firms to send recruiters to Harvard one week, Columbia the next, Chicago the following week, and so on.
"But with the job market so tight, last year schools began worrying that if law firms visited them later in the fall, the few job offers available would already be gone. So many top schools bumped up their on-campus interview weeks from October to September to finally August, before the school year even starts, because they wanted their students to have a chance to claim a job slot before their counterparts at other schools did."
...
"In February the organization that creates guidelines for legal recruiting process, NALP, released new rules about how long job offers could stay open, a measure intended to curb this interviewing arms race. But the new guidelines have not so far inspired any coordinated new schedule for interviewing process. "
...
The article closes with a news release from Northwestern: Northwestern Law, Jones Day Agree to On-Campus Interviewing in September
"CHICAGO --- Northwestern University School of Law and the global law firm Jones Day announced today July 26 that the firm will conduct its on-campus interviews for 2011 summer associates in September instead of during the law school's official on-campus interviewing (OCI) program, which begins Aug. 11. In a move benefiting both students and law firms, Jones Day will conduct interviews on behalf of its 14 U.S. offices on Monday, Sept. 13.
"Jones Day joins Northwestern Law in the belief that the current recruitment system has created a competitive race among law schools and law firms to conduct on-campus interviews earlier. The result is an inefficient system that does not serve employers or student applicants well, according to the law school and law firm.
"The current system discourages the efforts of law firms to learn about all the competencies (over and above grades) of potential associates," according to David Van Zandt, dean, Northwestern Law. "It also requires firms to make employment decisions and predictions about their hiring needs too far in advance of permanent start dates.
"The compression of summer associate interviews in August is also problematic for students since it constrains their time to make sensible decisions about with whom to interview, to adjust interviewing techniques based on what they learn during the process, or to make sound decisions about offers of employment," said Van Zandt. "It contributes to a frequent lack of fit between graduates and the law firms, which inevitably leads to higher attrition levels for the firms."
"Taking this step with Northwestern will help show that a more balanced, less frenzied approach to on-campus recruiting is not only still possible, but indeed desirable for all concerned -- students, law schools and law firms," said Greg Shumaker, firmwide hiring partner at Jones Day.

"CHICAGO --- Northwestern University School of Law and the global law firm Jones Day announced today July 26 that the firm will conduct its on-campus interviews for 2011 summer associates in September instead of during the law school's official on-campus interviewing (OCI) program, which begins Aug. 11. In a move benefiting both students and law firms, Jones Day will conduct interviews on behalf of its 14 U.S. offices on Monday, Sept. 13.
"Jones Day joins Northwestern Law in the belief that the current recruitment system has created a competitive race among law schools and law firms to conduct on-campus interviews earlier. The result is an inefficient system that does not serve employers or student applicants well, according to the law school and law firm.
"The current system discourages the efforts of law firms to learn about all the competencies (over and above grades) of potential associates," according to David Van Zandt, dean, Northwestern Law. "It also requires firms to make employment decisions and predictions about their hiring needs too far in advance of permanent start dates.
"The compression of summer associate interviews in August is also problematic for students since it constrains their time to make sensible decisions about with whom to interview, to adjust interviewing techniques based on what they learn during the process, or to make sound decisions about offers of employment," said Van Zandt. "It contributes to a frequent lack of fit between graduates and the law firms, which inevitably leads to higher attrition levels for the firms."
"Taking this step with Northwestern will help show that a more balanced, less frenzied approach to on-campus recruiting is not only still possible, but indeed desirable for all concerned -- students, law schools and law firms," said Greg Shumaker, firmwide hiring partner at Jones Day.

Squirrel game theory
Natalie Angier reports on squirrel game theorists in the NY Times: Nut? What Nut? The Squirrel Outwits to Survive
"But the squirrels don’t just bury an acorn and come back in winter. They bury the seed, dig it up shortly afterward, rebury it elsewhere, dig it up again. “We’ve seen seeds that were recached as many as five times,” said Dr. Steele. The squirrels recache to deter theft, lest another squirrel spied the burial the first X times. Reporting in the journal Animal Behaviour, the Steele team showed that when squirrels are certain that they are being watched, they will actively seek to deceive the would-be thieves. They’ll dig a hole, pretend to push an acorn in, and then cover it over, all the while keeping the prized seed hidden in their mouth. “Deceptive caching involves some pretty serious decision making,” Dr. Steele said. “It meets the criteria of tactical deception, which previously was thought to only occur in primates.”

Paid drug trials
The Chronicle of Higher Ed has a (gated) story about professional volunteers for drug trials: Inside the Risky World of Drug-Trial 'Guinea Pigs'
"Mr. Abadie spent time with anarchist activists who are attracted to guinea-pigging because of the flexibility it offers. Between 1996 and 2002, that milieu was documented in Guinea Pig Zero, a Philadelphia zine published by and for activist medical volunteers.
"But Mr. Abadie's book also examines two other types of medical volunteer. First, he describes transient, economically struggling people who travel from place to place in search of lucrative trials. These volunteers are often less educated and more socially isolated than the anarchists.
"Second, Mr. Abadie spent months at an HIV clinic where patients were participating in long-term trials to determine the effectiveness of new drug combinations. That environment is very different from the Phase 1 trials described elsewhere in the book. At the clinic, the HIV patients knew they had a personal stake in the development of new drugs, and the financial compensation they received was much smaller. Even though they were taking risks by participating in the drug studies, Mr. Abadie says, those volunteers seemed to reap psychological gains."
I'm reminded that we teach kids that the tooth fairy buys their baby teeth for money. But of course many sales of body parts are regarded as repugnant transactions and are illegal, while paid drug trials are legal.
"Since 1980, when Phase 1 drug tests on prisoners were banned in the United States, university medical schools and pharmaceutical companies have depended on volunteers like Mr. Little to test the safety of new drugs. Bioethicists have devoted thousands of pages to debates about the system. Some fear that high payments for volunteers are an "undue inducement" that might tempt them to take risks against their better judgment. Others say that people like Mr. Little are consenting adults who are reasonably capable of assessing danger.
"Most of those debates have been conducted in the abstract. But now an anthropologist has produced a study of several dozen medical volunteers, including Mr. Little. Roberto L. Abadie, a visiting scholar in the health-sciences program at the Graduate Center of the City University of New York, spent a year living in youth hostels and group houses in Philadelphia, trying to get a sense of why volunteers do what they do and how they understand their risks.
"He offers his findings in The Professional Guinea Pig: Big Pharma and the Risky World of Human Subjects (Duke University Press, August). The book's primary purpose is to offer a detailed description of medical volunteering and its contexts, not to weigh in on the ethics of clinical trials. But after his year in the field, Mr. Abadie does have opinions about policy: Volunteers underestimate their long-term risks, he says, and universities should do more to protect them."..."Mr. Abadie spent time with anarchist activists who are attracted to guinea-pigging because of the flexibility it offers.

Internet dating moves (back) into the real world
Computers can provide a multitude of services, and a new class of dating services uses them not to help people meet others, but to preserve their anonymity until they decide to relinquish it: The New Dating Tools: A Card and a Wink.
"This is the next generation of online dating. Unlike traditional dating sites where members spend hours on computers writing autobiographies and scrutinizing photographs, a raft of newfangled dating tools are striving to better bridge the gap between online and real-world romance.
"Some companies offer a combination of flirty calling cards and Web pages. Others operate dating applications that use the global positioning systems in cellphones to help local singles find one another.
"All of them contend they are superior to big online dating sites like Match.com; eHarmony.com because meeting people is faster, more organic and less formal. And participants are not limited to a database of members: the world is their dating pool.
“It’s almost like you’re shopping online,” said Ms. Cheek, “but you’re shopping in real life.”
"At the same time, these hybrid dating tools still enable users to keep their names and personal information private for as long as they like.
"Ms. Cheek, an architect who works part-time in sales for a high-end Manhattan furniture company, founded one such venture, Cheek’d, which had its debut in May. Users receive calling cards to dole out to alluring strangers they encounter in their everyday lives, be it in a club or in a subway on their morning commute. Recipients of the cards can use the identification code printed on them to log onto Cheekd.com;and send a message to their admirer. A pack of 50 cards and a month’s subscription to Cheek’d, where users can receive messages and post information about themselves, is $25. There is no fee for those who receive cards to communicate with an admirer through the site."
...
"On each red FlipMe! card is an explanation for the recipient: “I’ve said ‘what if’ too many times ... not this time.” A pack of 30 cards and a three-month membership to flipmedating.com is $24.99. The cards, which all say the same thing, are sold online and in some salons and spas in the Northeast. A cellphone application is in the works."
...
"Card users said companies like FlipMe! and Cheek’d are emboldening them to approach people who might otherwise have been missed connections. They also appreciate how the companies reverse the online dating process — observe someone in person first, then send an electronic message. There’s no need to contend with false advertising on dating Web sites."
...
"Other companies are helping singles connect through location-based technology on their mobile phones. In the last few years the number of Web sites and applications like Grindr, Are You Interested? and Urban Signals, has swelled.
"One of the biggest is the free iPhone dating application Skout, which recently surpassed its millionth member. Skout uses a cellphone’s global positioning system to help users to find like-minded people within a walkable radius of one another. (For safety reasons, Skout does not identify a user’s precise location.) Those who sign up for the application create basic profiles with photographs and then use an instant message feature to communicate when they are within range of each other. Then, they can arrange a mutual meeting spot.
“It’s really combining the best of online dating and real-world people discovery,” said Christian Wiklund, Skout’s founder."

Advice for Wake County schools
It sounds like the troubled Wake County school system is about to get some advice on school choice. But, to the extent that you can judge from a newspaper story, they may not be looking for the right kind of advice, or in the right places (more about right places at the end...)
Here's the problem. Suppose you want a school choice plan, and would like to be able to say that it results in lots of families getting their first choice. That might be hard, if the most popular schools are overdemanded. But you could adopt a choice procedure that is punitive to those who fail to get the school they list as their first choice. That would present families who liked overdemanded schools with a risky decision, and the safe choice would be to choose a school (e.g. their local school) that they could be pretty confident of getting into, and saying that was their first choice. When parents feel compelled to play it safe this way, it looks like they are getting their first choice, even though they aren't really. Once upon a time that was how schools were chosen in Boston, and that kind of system is still used in some places, including Cambridge, MA.
So, here's the news story that makes me worry about this.
Idea intrigues Wake school board factions
"A controlled choice model for Wake would create a dozen or more attendance zones, each of which would reflect the makeup of Wake County - no rich zones or poor zones, said Massachusetts education consultant Michael Alves, who's helped design dozens of such systems nationally.
"Parents would be able to choose from a wide range of school offerings in their zone, with a lottery to make another choice when schools are too crowded or apply to a countywide system of magnets, Alves said. He will be in Raleigh on Tuesday for a presentation before the board committee charged with developing a new plan. Parents would not be guaranteed of getting their first choice, but in systems that use controlled choice, such as Lee County, Fla., and Cambridge, Mass., a large majority do.
"We've been looking at a number of plans from a number of districts across the country," board chairman Ron Margiotta said Wednesday. "He's very close to what we have in mind, to my understanding."
Here's some background on School choice that pays attention to making it safe for families to reveal their true preferences. Which brings me to where the Wake County school board can look for advice.
One of the world's experts on the design of school choice systems is Atila Abdulkadiroglu, who is a professor at Duke, in Raleigh NC, the largest city in Wake County. So he's on location. Here is Atila's blog on school choice.

Abandoned horses not headed for foreign tables
Speaking of the pony express, Activists Keep Nev. Horses From Going to Slaughter
"With the financial backing of the wife of oil tycoon T. Boone Pickens and others, activists on Saturday purchased almost all 174 horses up for sale at a state-sanctioned auction in Nevada to keep the horses from going to the slaughterhouse.
"Stephanie Hoefener of the Lancaster, Calif.-based Livesavers Wild Horse Rescue group said activists purchased 172 horses for $31,415. The other two horses were acquired by private individuals for their personal use, she said.
...
"The horses were rounded up by the U.S. Bureau of Land Management last month near the Nevada-Utah line and turned over to the Nevada Department of Agriculture for disposal.
"Agriculture department officials acknowledge the stray horses could have wound up at slaughterhouses because they did not have the federal protections afforded to wild-roaming horses.
"The horses are believed to be strays or descendants of horses abandoned by private owners over the years in Pilot Valley north of West Wendover.
''For advocacy groups to step up to the plate and make a financial commitment like this to save the horses, we think this is a wonderful thing,'' Nevada Department of Agriculture spokesman Ed Foster said.
"Jill Starr, president of Lifesavers, said the purchase of the horses at the Fallon auction was made possible by the financial backing of Madeleine Pickens and other donors.
"Starr said high bidders of such horses usually are representatives of slaughterhouses in Mexico and Canada. The meat of the horses is processed for sale in Europe and Asia, where it fetches as much as $25 a pound, she added. "

Express mail 1.0
The Pony Rides Again (and again)
" The heroic, nearly 2,000-mile delivery of mail across the country hemorrhaged money, from the first day a rider saddled up until the click of the transcontinental telegraph shut it down 78 weeks later. "
