Match Day for New Doctors, the book

When I blogged last month about Match Day for new doctors, I mentioned Brian Eule's new book, Match Day: One Day and One Dramatic Year in the Lives of Three New Doctors. A copy of the book arrived in my mailbox last week, with a note from the author, who had interviewed me while writing it.

I've noticed before that good science writers tend to write about scientists at least as much as they write about science. But I guess I am not in the habit of anthropomorphizing markets, since I was nevertheless surprised to read the following characterization of the market for new medical residents.

"If you wanted to put a face on this faceless machine, it would have a thick black beard, beginning to go gray. It would have a receding hairline. It would wear glasses, squint when smiling, and present a big forehead adding to its contemplative appearance. It would look, in this case, much like an economist at Harvard University named Alvin Roth."

Fortunately, most of the story is about the three couples he follows through the resident match and their first year of residency. I didn't reach a point at which I could put the book down for the first time until after the first hundred pages, since the story carried me along, and I wanted to find out where they matched. Way to go, Brian.

Real money trading in Massively Multiplayer Online Games

Want to know the current price of gold? Check out http://www.mysupersales.com/. You won't find the traditional store of value there, but rather the virtual gold used in massively multiplayer online games like World of Warcraft. You could earn gold by playing the game, and use the gold you earned in the game to buy equipment "in-game". But you can also buy gold from "gold farmers," in China and elsewhere, using real money, and having the gold delivered to you inside the game. Here's a paper by Richard Heeks of Manchester that says it's a surprisingly big business: "It employs hundreds of thousands of people and earns hundreds of millions of dollars annually. "

Real money trading for online gold also involves a set of transactions that some gamers and game operators find repugnant: operators go to great lengths to stop it. Here's a statement against the practice by the proprietors of World of Warcraft. And an article at a gamer site begins
"Is gold selling like pornography: something more of us do than admit? A shameful secret, something indulged alone and at night, in front of the screen; or during a lunchbreak, safely away from a partner, when a quick credit card or PayPal transaction will go unnoticed by others in-game?"

A further article recounts how some game operators have tried changing the rules on in-game transactions to make real money purchases less practical, while other games have decided to allow players to enter for free, and finance the game by officially selling equipment for real money:

"The most probable trend is that the games become 'free-to-play', and the operators sell gold or other in-game items by themselves. There are a lot of so-called F2P MMOs, and they mainly get revenue from selling in-game items.
"One of the most famous examples is a Chinese online game developer and operator - Giant Interactive Group, they got listed in the NASDAQ by selling in-game items in ZhengTu, a game they developed and published in China. So I don't think the game publishers will be willing to share the cake with the gold sellers.
...
"According to Vili Lehdonvirta of the Helsinki Institute for Information Technology, an expert on virtual consumerism, real money trading is now well-established outside of the MMO sphere.
"Several Korean online games successfully sell performance-based items to users," he says in his recent report Virtual item sales as a revenue model: identifying attributes that drive purchase decisions. "

Forward contracts on sporting events

How should tickets for big sporting events be sold, in advance of information about which teams will play in them? American baseball's World Series, the NCAA's basketball Final Four, and other such events are elimination tournaments. So it is known well in advance that there will be some important games, but which teams will play (and hence which fans will most want to attend) is known only quite near the event.

This makes the market less thick than it might be far in advance, and requires fast market clearing once the relevant information becomes known. In turn, this opens the market to third party brokers, and scalping.

Contingent contracts might be a solution (e.g. a market in which I can buy a ticket to the World Series contingent on the Boston Red Sox being in the game).

Felix Salmon blogs about a paper exploring a related idea (because of a fear that contingent contracts might be regarded as repugnant): Selling forwards for sporting events.

"Preethika Sainam of Indiana University, along with two colleagues from Chapel Hill, has an interesting paper suggesting that sports organizations shouldn’t sell tickets to big sporting events, like the finals of the Final Four, where the teams who will be playing are unknown. Instead, they say, they should sell options to buy tickets at a certain price once it’s known who’s going to be playing. This system, they say, will raise more money in ticket sales, will make fans happier, and will reduce scalping.
The interesting thing is that reading between the lines of the paper, it seems that selling options is actually the second-best solution to these problems. The best solution would be to replace some (but not all) of the tickets with team-specific forwards, which expire worthless if that team doesn’t make the finals. That would allow the “team-oriented” fans to buy forwards rather than tickets which they might not want if their team fails to make it to the finals; it would allow “game-oriented” fans to buy tickets to the finals just like they can right now; it would mean that many more tickets could be sold in total (for the final match-up, you can sell 32 times as many forwards as there are seats), which would reduce the supply/demand imbalance which often drives scalping.
Professor Sainam, however, reckons that the forwards idea is a non-starter, for reasons of optics: she worries, she tells me, “that fans could perceive the league as profiting unduly from the situation”. And so the options option is the next best thing. "

Update on the Economics Job Market "Scramble"

The Economics Job Market “Scramble” for New Ph.D.s opened for registration on March 24, became visible to participants the next week, and was scheduled to go dark on April 11. Its purpose was to give applicants and employers a low cost way to see who was still on the market.

It's too early to know how many interviews were conducted with the help of the scramble, or how many of those will eventually result in hires. (In fact, the market is so decentralized that there is no reliable way to gather data on that, beyond surveys that the AEA sends out to participants). But there is information on how many applicants and employers registered for the scramble.

There were 395 applicants registered, of whom 362 made further information about themselves available at a URL.
223 of these show up when sorted as 2009 PhD candidates, 47 as 2008 Ph.D.s, and 125 before 2008. (These numbers aren't quite right, since they account for all the candidates, and I noticed at least one without a Ph.D.)

There were 78 employers, advertising 87 positions. 17 of the 87 positions were not made visible (even) to registered applicants; these employers preferred to be able to contact applicants but not to be contacted by them.

The visible employers consisted of
20 universities with graduate programs
18 four year colleges
10 consulting or research
7 Federal government
4 Banking or finance
2 other

The registered employers who chose to remain invisible consisted of:
8 Universities with grad programs
3 four year collegs
3 Federal government
2 consulting or research
1 banking or finance

Good luck to all those still seeking a match.

Market for sugar daddies

Not all dating sites have marriage as their goal.

The NY Times Sunday magazine has an article called Keeping Up With Being Kept, about the website SeekingArrangement.com, which advertises itself as "the elite sugar daddy dating site, for mutually beneficial relationships." As the site makes clear, money is part of the benefit in one direction, but as the story also makes clear, the line between dating and sex work is fuzzy, and some of the relationships that develop are potentially rewarding.

Apparently the law is on the side of the site: "...since the 1970s, courts have ruled that as long as the woman is paid for some service besides sex — housecleaning, companionship — the arrangement is not the equivalent of prostitution."

The complication is summed up by one young woman who apparently has some experience with this marketplace:

"“When these sugar-daddy relationships go the way I think they should go, the lines are pretty blurry between that and a typical boyfriend-girlfriend relationship,” she said. “And when they go the way I don’t think they should go, the lines are blurry between that and sex work.” "

The website also suggests that you "Visit our other dating sites: SeekingMillionaire.com (Millionaire Dating) & SeekingFantasy.com (Adult Dating)"

The Times story puts the matter in (market) context by considering some of the history of courtship :
"MOST PEOPLE WOULD LIKELY BE appalled to learn that a daughter — or father — was using SeekingArrangement.com. Beth Bailey, a Temple University historian of courtship, said that her first reaction to the site was “revulsion.” But when she reconsidered it within the historical context of dating, she had a somewhat different response.
Heterosexual relationships, including marriage, have long involved economic transactions, but Bailey points out that when men provided financial security, they traditionally did so in exchange for a woman’s sexual virtue (and potential to bear and rear children), not for sexual thrills. For that, they often turned to prostitutes and mistresses, involving a more frank money-for-sex exchange. It’s only in the last century that money has been traded — albeit indirectly — for sexual attention from “respectable” unmarried women. In the early 1900s, courtship shifted from girls’ porches or parlors to a commercial venture: a date. Etiquette manuals of the time were explicit — boys were to pay for meals, entertainment and transportation, and in return, girls were to provide well-groomed company, rapt attention and at least a certain amount of physical affection."

Market design and experimental economics

Noam Nisan asks "should “algorithmic game theory” (in the broad sense) also put significant energy into experimentation? " Or should experiments remain in the province of economists, and market designers who deal with human (as opposed to computer) agents? He sees some possibilities that computer scientists should also entertain experiments, about the connection between computerized systems and their human users.

This of course raises the possibility that the interaction of computer science theorists with economists will expand to include psychologists doing cognitive engineering, the part of human factors engineering most concerned with cognition, and human-computer interaction. (Here's my favorite cognitive engineering website, soon to be updated.)

Nisan also has some interesting asides, and one particularly caught my eye:
"I never quite understood the difference between experimental economics and behavioral economics. My impression is that it is simply a question of your attitude towards game theory: experimental-pro, behavioral-con. The anti-game-theory bias is probably not that of its founders Kahneman and Tversky. Shortly after winning the Nobel prize in economics in 2002, I heard Kahneman talk at a dinner held by the Hebrew University’s rationality center. His point was that while most psychologists would immediately dismiss the economic assmptions of rationality as absurd regarding human beings, the greatness of his co-author Tversky was to realize that there was an important underlying truth to this point of view, and hence that it was interesting to carefully study its limitations. "

I think that this view was more accurate in the early days. Today, I think that "behavioral economics" means the broad effort to include (a little or a lot) psychology in economics, and in that sense (to paraphrase),we are all behavioral economists now, whether or not we do experiments. Experimental economists, however, do experiments.

Why can't you eat horse meat in the U.S.?

The first sentence of Repugnance as a Constraint on Markets asks "Why can't you eat horse meat" in California? The answer is that it's against the law. But while similar bills to outlaw the sale of horse meat for human consumption have passed by big majorities in the U.S. House of Representatives, they have never managed to pass into law. Nationally such bills are opposed (as they were in California) by many horse breeders, cattle ranchers, and veterinarians. Nevertheless, the department of Agriculture removed funds for inspection of slaughterhouses.

Now the NY Times reports: Surge in Abandoned Horses Renews Debate Over Slaughterhouses .

"Emaciated horses eating bark off trees. Abandoned horses tied to telephone poles. Horses subsisting on feces, walking among carcasses.
As the economy continues to falter, law enforcement officers in Kentucky and throughout the country are seeing major increases in the number of unwanted and neglected horses, some abandoned on public land, others left to starve by their owners.
The situation has renewed the debate over whether reopening slaughterhouses in the United States — the last ones closed in 2007 — would help address the problem. Some states, Missouri, Montana and North and South Dakota, for example, are looking at ways to bring slaughterhouses back. "

Malls

Shops provide positive externalities to each other. Both stores and restaurants like to be where there is good foot traffic from other restaurants and stores, and some stores like to cluster together (jewelers, and automobile dealers) to draw comparison shoppers who might not make the journey to a destination that had only a single shop. Part of the problem that towns face in nurturing thriving Main Street/downtown shopping districts is that it is hard to get the right mix when each commercial tenant negotiates separately with each landlord.

Malls--privately owned shopping centers--attempt to internalize this externality, and provide that right mix. (So, not all tenants of a mall have to pay the same rent per square foot; some tenants may provide traffic that raises the profitability of other tenants.) The marketplace designer is the mall owner, sometimes in negotiation with the tenants. (This is what led in Massachusetts to the Solomonaic judicial ruling that a burrito is not a sandwich, when Panera bread sued a mall claiming that the clause in its lease guaranteeing that it would be the mall's only sandwich shop was violated when the mall leased space to a burrito chain.

In the current recession, in which commercial real estate is hard to fill, malls are struggling to keep a mix of tenants who will draw traffic for each other: Malls Test Experimental Waters to Fill Vacancies . While some malls will fail, others may manage to bring new kinds of tenants (the article suggests wave machines and community colleges).

The stakes are high, since many malls are designed as easy-to-park-at destinations that must draw shoppers to them. If some shops go dark, malls will face the same kind of struggle as do less planned retail commercial neighborhoods.

Market for eggs and sperm

The Boston Globe reports Recession spurs egg and sperm donations
Giving provides extra income.

"Couples, and some single women, pay $20,000 to $30,000 for an egg donation, in vitro fertilization, and transfer to the recipient. Donors generally must be healthy nonsmokers between ages 21 and 32 with a good family health history, "reasonably educated and reasonably attractive," Benardo said. Screening involves physical, psychological, and genetic testing. If accepted, the woman undergoes hormone injections, then a surgical procedure to remove her eggs. Fees paid to the donor generally range from $5,000 to $10,000. Recipients choose prescreened donors."
...
"In Charlestown, NEEDS (National Exchange for Egg Donation and Surrogacy) also reports a 25 percent increase. "Very few of them will say just straight out it's for the money," said NEEDS manager Jan Lee. "They don't want to sound like a money-grabber. We ask them if they're applying because they need the money or out of the goodness of their heart, and they say both." "
...
"[Dr. Vito Cardone, founder of Cardone Reproductive Medicine & Infertility] cautions against women seeing this as a gold mine.
"The money that's given is limited; it's not going to be something to create a yearly revenue to get them through life," he said.
He believes in compensating women for their time and trouble but said there needs to be "some ethics to it" - both an altruistic motive and a monetary limit.
"When I see people who want to 'sell' their eggs for $20,000 or more it makes no sense, because then it becomes commercial, like selling any other thing," he said. "There has to be a little bit of kindness, because these couples have had a lot of hardship and desire a child very strongly." "
...
" Sperm donations are also on the increase, although they pay much less - an average of $85 to $100 per donation. Such "banks" generally require that the donor be at least 5-foot-8, a college student or graduate between the ages of 18 and 38, and in good health.
California Cryobank, which has offices in Cambridge, recruits largely on college campuses and asks each donor for a year's commitment, with the average donor contributing 2-3 times a week.
In the past six months, applications are up 20 percent, said Scott Brown, communications manager. "I think the recession has certainly opened up interest," he said. But less than 1 percent of applicants are chosen, based on family history, a physical exam, and analyses of blood, urine, and semen. "It's tougher to get into the Cryobank than into Harvard," Brown said."

Repugnant transactions: cartoon edition

Prophet Muhammad Cartoon Goes on Sale in Denmark

"A Danish press freedom group said Wednesday it is selling copies of a cartoon of the Prophet Muhammad that caused outrage across the Muslim World.
Some 1,000 printed reproductions of a drawing depicting Islam's prophet wearing a bomb-shaped turban are being sold for 1,400 kroner ($250) each, said Lars Hedegaard, chairman of the Danish Free Press Society.
...
Hedegaard said Danish artist Kurt Westergaard, who drew the cartoon in 2005, had given the society permission to produce the copies and sell them. Each numbered copy has been signed by Westergaard, Hedegaard said.
...
Westergaard has been living under police protection since an alleged plot to murder him was discovered last year.
Twelve cartoons depicting the prophet, including the one by Westergaard, were published in the Jyllands-Posten newspaper in 2005.
The following year, they triggered massive protests from Morocco to Indonesia, with rioters torching Danish and other Western diplomatic missions. Some Muslim countries boycotted Danish products."

Same sex marriage in Iowa, and New England

Another legally banned transaction between two willing adults that some third parties find repugnant has fallen, this time in Iowa: Gay Marriages Expected to Begin in Iowa April 24.

The different roles of judges, politicians, and voters in this matter are interesting to consider.

"The Iowa Supreme Court on Friday unanimously upheld a lower-court ruling that rejected a state law restricting marriage to a union between a man and woman.
...
"Only Massachusetts and Connecticut currently permit same-sex marriage. For six months last year, California's high court allowed gay marriage before voters banned it in November."

In MA and CT also, the ban on same-sex marriage was ended by judges, not legislators or voters.

Now in Vermont, a legislature has moved: Vermont Legislature Makes Same-Sex Marriage Legal .

"The Vermont Legislature on Tuesday overrode Gov. Jim Douglas’s veto of a bill allowing gay couples to marry, mustering one more vote than needed to preserve the measure.
The step makes Vermont the first state to allow same-sex marriage through legislative action instead of a court ruling. The law goes into effect Sept. 1."

The NYC high school match, continued

When I recently blogged about The NYC High School Match, I focused on the many students who received one of their choices. As I mentioned, "The NYCDOE reports that of 86,000 students looking to enter the 9th grade, 44,012 students received their first choice school, and 7,455 could not be assigned to any of their (up to 12) choices."

Those unmatched students will now go through a supplementary match process. Many of them likely ranked many fewer than 12 choices, and will now have to select among schools that still have vacancies. Needless to say, this is a serious setback for some of them. (Here's a story from the Daily News: Parents fume as kids miss cut for top city high schools).

Michael Hickins, a reporter from Information Week (who writes that his daughter just went through the process) was referred to me by the NYCDOE, because of the work I did to help design the process, along with my colleagues Atila Abdulkadiroglu and Parag Pathak. Here is how our conversation (and others he had) is reflected in his report: NYC Board Of Ed's Algorithm Not Academic.

Helping kids get into good schools is one of the most important things we can do for them, and this is why it's important for schools to use modern matching technology, as NYC does, to try to get as many kids well matched as possible. It's agonizing that we can't provide enough great school places for everyone. There's only so much that can be done with matching technology, which can allocate existing places, but doesn't create good new schools. School systems need our support in other ways as well.

Markets for organs

In Reward Organ Donors , Sally Satel writes in the Asian WSJ about the recent changes in Singapore law regarding compensation for donors (see my previous posts here and here). She goes on to outline the design of the kind of market she would like to see, and ways in which perceived repugnance might be addressed.

"My colleagues and I suggest a system in which a donor can accept a reward for saving the life of a stranger. A third party (the government, a charity or insurer) would provide the benefit and newly available organs would be distributed to the next in line -- not just to the wealthy. Donors would be carefully screened for physical and emotional impediments to safe donation, as is currently done for all volunteer living kidney donors. Moreover, they would be guaranteed follow-up medical care for any complications.
Many people are uneasy about offering lump-sum cash payments. A solution is to provide in-kind rewards, such as a down payment on a house, a contribution to a retirement fund or lifetime health insurance, so the program would not be attractive to people who might otherwise rush to donate on the promise of a large sum of instant cash.
Not only will more lives be saved through legal means of donor rewards, but fewer people will haunt the black-market organ bazaars of places like China, Pakistan, Egypt, Colombia and Eastern Europe. The World Health Organization estimates that 5% to 10% of all transplants performed annually -- perhaps 63,000 in all -- take place in these clinical netherworlds."

Kidney donors (and advertising)

Several recent stories about kidney transplants are worth noting, not least for their focus on donors: how to find one, how their gifts are effectively used, and how they are and might be compensated. (This leads to some thoughts on the various roles that advertising, through personal communication, news stories, and commercially, might play at various points).

At Salon, Whaddaya have to do to get a kidney around here? Frances Kissling writes about the gratifying responses she received when she carefully let her friends know that she was in need of a kidney transplant. She writes:
"I think I instinctively knew what I had to do. I'd spent a lot of my time raising money, and I had that Bible verse "ask and you shall receive" burned into my consciousness. I decided to compose an e-mail about my need. In it, I shared my sense of the adventure before me and asked if anyone would like to give me one of their kidneys. I noted: "To be dependent on the generosity of others is a new experience for me and I am thinking a lot about what it means to share one's body with another person. Also trying to figure out how I ask for a gift that I really want without expectation or making friends and colleagues uncomfortable." "

About the ongoing discussion of providing compensation for donors, whe writes
"Even without incentives, no group of do-gooders is treated with more suspicion by the medical community than living organ donors. Even a free glass of orange juice or an unnecessary lollipop given to a donor is interpreted by some leaders in the field as a "bribe" or a crime. Appropriate concern for the international organ trafficking problem (WHO estimates that the annual total of internationally trafficked kidneys is about 6,000) has so distorted the concept of altruism and eroded the principle of mutual respect that potential kidney donors are denied the basic safety net that a just and giving society should provide people who offer to risk their own lives to save the lives of others. And let's be clear. The best way to stop first-world people with money from exploiting poor people by bargain basement organ trafficking is to procure more organs from well-informed, healthy and autonomous people in the first world."

Among her bottom lines: if you need a kidney, let your friends know.

From Australia, Kidney Exchange is making continued progress: the news story Chain of goodwill saves lives reports that Western Australia's Paired Kidney Exchange Program has performed an altruistic donor chain, involving three transplants. As the technology progresses for effectively using altruistic kidney donations to enable multiple transplants, the benefits of such donations increase. And as the news of this spreads, it is likely more altruists will be moved to donate.

This brings me to the subject of advertising.

Apart from letting their friends and acquaintances know (and sometimes in preference to doing that) people in need of transplants sometimes advertise (see e.g. the story Ads, Billboard Plead for Organ Donations, or the site MatchingDonors.com).

In a column in the Los Angeles Times about how all sorts of transactions (particularly on the web) are funded these days by advertising, Joshua Gans is interviewed on the subject of repugnant transactions
"According to Joshua Gans, an economist at Melbourne Business School in Australia..., there's a social norm against repugnant transactions, such as paying for a kidney. In the last few years, too many transactions have become repugnant. "And if you need to make money to pay for the content ... and you can't get the consumers to pay, what do you do? Sell a related product, advertising," Gans told me. The good news is that at this point, I'm pretty sure The Times' sales staff will sell space on their kidneys."

Could someone actually finance a kidney donation by advertising? Jeff Ely at Cheap Talk offers this suggestion under the heading Organs for Money:
" I wonder if the following transaction would be considered taboo. I need a kidney, you have a spare. By law, I cannot pay you for the kidney and you would not give it to me without compensation. So instead I buy five minutes of primetime network TV air, say in the middle of American Idol, to broadcast my documentary about you telling the world what a heroic human being you are, how you saved my life and where to send you donations."

(In the nothing is too bizarre to contemplate category, Tyler Cowen at Marginal Revolution points to a laptop company that offers to help defray the cost of well attended funerals in return for being allowed to advertise at them: Advertising markets in everything)

More on recommender systems for escorts

Scott Cunningham of Baylor writes:

"I saw today your post on the screening sites that prostitutes use ["Problem customer" registries for prostitutes]. I just wanted to pass along to you a paper I'm currently working on with Todd Kendall called "Prostitution 2.0: Estimating the Effect of the Internet on the Market for Commercial Sex in the US."
http://business.baylor.edu/scott_cunningham/Research_files/pro20-4.pdf
"We have been surveying online prostitutes for the last 10 months using data collected from The Erotic Review, which is a large "mall" that clients use to record detailed information about prostitutes in various cities. In the course of the surveys, we have been studying the way in which the Internet has facilitated improved screening, and even in some cases, signaling between clients and prostitutes. One of the more ingenious things that we have found is a case of signaling from clients to prostitutes wherein they send letters of recommendation to prostitutes, usually in the form of sending along information [from] another prostitute with whom they've already visited. This, we argue, has enabled prostitutes to update their beliefs that a new client is not a cop (or a violent client) because these letters are relatively more expensive for cops to send. A case in point - see this story about two police officers who were sleeping with prostitutes in Beaumont, Texas allegedly in order to make a case on a drug trafficker. When the public learned, the men were fired, and the officers are now suing the Beaumont, Texas police department for wrongful termination. (It's suggestive that indeed the private costs of using these kinds of methods are prohibitively high for cops, which we argue is evidence that the costs of signaling type to prostitutes is such that the separating equilibria and not the pooling equilibria is more likely to be happening). "

Here is The Erotic Review, and here is what they say about customers getting recommendations from escorts:

"TER White List
If you have a good reputation with the ladies, encourage them to visit the TER White List and submit a referral for you. The TER White List is an easy way for providers to give positive references about members they have seen. "

The NYC High School Match

The New York City Department of Education reports that the new high school match process continues to work well: More Than 80 Percent of Students Admitted to a Top Choice High School for Fourth Consecutive Year.


"The Department of Education conducts extensive outreach to families about the high school admissions process, beginning during the sixth grade. High school applicants receive the annual, 500-page High School Directory, which provides them with information about every high school. They also receive several other publications that guide them through the admissions process. In addition, the Department of Education hosts Citywide high school fairs, workshops, and information sessions for several months before students’ applications are due. Middle and high school administrators, guidance counselors, parent coordinators, and community partners help students and families evaluate their options and make informed choices.

"Students can list up to twelve high school programs on their applications in order of preference. Schools also rank students. Then, students are matched to the school they ranked highest that also ranked them. The admission process consists of three rounds: the first round for students applying to the City’s Specialized High Schools, the main round (this round), and the supplementary round for students not matched during the main round. "


The NYCDOE reports that of 86,000 students looking to enter the 9th grade, 44,012 students received their first choice school, and 7,455 could not be assigned to any of their (up to 12) choices.(The figures they give are for what we called rounds 1 and 2 of the new system, described in our paper discussed in a previous post, Matching students to high schools in NYC . The unmatched students will next be informed of the schools that still have vacancies, and be asked for a new preference list of up to 12 choices. Here's a link to the paper again: Abdulkadiroglu, Atila , Parag A. Pathak, and Alvin E. Roth, "Strategy-proofness versus Efficiency in Matching with Indifferences: Redesigning the NYC High School Match,'' revised, November, 2008, American Economic Review, forthcoming. )

Repugnance, and regulation of new markets: surrogate wombs

One of the reasons that people are reluctant to consider legalizing markets for new and possibly repugnant transactions is that it is easy to imagine that bad things can happen in new markets. (Credit default swaps, anyone?). The question of whether it should be legal to buy and sell kidneys for transplantation is the example I've most frequently written about.

But now comes a story about the market for surrogate wombs. A company that did the matchmaking between infertile couples and surrogate moms, and had the couples set up escrow accounts to make guaranteed payments to the surrogate mom over the course of the pregnancy, has collapsed, and the funds with which it was entrusted have disappeared. Here's the story in Slate: If you stop paying a surrogate mother, what happens to the fetus?

"That's the scenario unfolding in California. The victims are couples and surrogates who met through SurroGenesis, a company "dedicated to assisting infertile couples to have a baby through third-party assisted reproduction." Hiring a surrogate through the company is expensive, as you'll see from its long list of fees. But don't worry: The company offers to "arrange for opening of [a] trust account" that will cover your expenses. Specifically, according to the Los Angeles Times, its clients say "SurroGenesis recommended that prospective parents set up trust funds administered by the Michael Charles group," its partner company.
The parents handed over the money. From this, the companies were supposed to pay the surrogates. Now, the Times reports, payments have stopped. In fact, the New York Times adds, "SurroGenesis told clients on March 13 via e-mail that their money was gone. Lawyers say that as much as $2 million may be missing, with some couples losing as much as $90,000."
...
"Surrogates aren't mercenaries. But they do need to be paid for their sacrifices. With every week that passes, they endure more of pregnancy's burdens. They submit to exams, tests, and other procedures. They take on serious medical risks. They forgo activities that might harm the fetus. They lose the ability to commute to and work at other jobs. They have bills to pay. At least one abandoned surrogate says she has received an eviction notice.
"If you stop paying your surrogate, she needs to quit and find another job, just like any other worker. But surrogacy isn't like any other job. The only way to quit a pregnancy is to abort it."

So, we've got a very bad market failure here. Either surrogacy needs to be better regulated, or private institutions have to emerge that will provide more security for these difficult transactions.

Is this kind of failure a reason to make surrogacy illegal? I think that would be way premature; I'm guessing there are happy children being brought up in loving families, borne by surrogates who feel well compensated. But it does mean that, when we debate whether to legalize selling kidneys, for example, the "market design" questions of how any such market might be regulated, and whether the worst failures could reliably be avoided, should be at the center of the discussion.

"Yup, the law (in Massachusetts) would make it a very serious crime — tantamount to child pornography — to make, and distribute "with lascivious intent," "any visual material that contains a representation or reproduction of any posture or exhibition in a state of nudity" involving anyone age 60 or over, or anyone who has "a permanent or long-term physical or mental impairment that prevents or restricts the individual’s ability to provide for his or her own care or protection."
..."The bill text is here; the provisions that would be amended are here and here; and the definitions of "elder" (anyone age 60 or older) and "person with a disability" ("a person with ) are here. "

A no-longer repugnant marriage transaction?

The Telegraph reports: Gordon Brown has opened talks with Buckingham Palace on removing the 308-year-old law which bars members of the Royal Family from marrying Roman Catholics.

"Monarchs and members of their family in the order of succession have been banned from marrying Roman Catholics since the Glorious Revolution of 1688, when the Catholic James II was overthrown in favour of the Protestant William of Orange. The prohibition is enshrined in the Bill of Rights passed that year, and the 1701 Act of Settlement.
Rewriting the Act of Settlement requires the consent of all 53 Commonwealth countries, and Mr Brown hopes to discuss the proposal at the Commonwealth summit in November. He has already held private talks about his plans with some Commonwealth leaders.
Sources close to the Prime Minister stressed that the plans would not undermine the Establishment of the Church of England, and that the monarch would retain the role of head of the Church."
...
"During the current Queen's reign, two members of the Royal Family - Prince Michael of Kent and the Earl of St Andrews - renounced their rights of succession after marrying Roman Catholics. Last year, it was announced that Autumn Kelly had renounced her Catholic faith before she was able to marry Mr Phillips."

"Dr Harris said of his Bill: "The Bill will remove the uniquely discriminatory stipulation which currently exists - that an individual in the line of succession to the throne can have a civil partnership with a Catholic, can marry a Muslim or atheist, but can not marry a Catholic."

College admissions: waiting lists

Today is the day when the most highly selective (i.e. lowest percentage of admits) colleges will inform students who they have decided to admit in their regular admissions cycle. (The Ivies are due to announce at 5PM Eastern time, Stanford and some others tomorrow...most less selective colleges and universities have already announced...).

The prospects for college admissions this year sound a little confusing, at least in the NY Times: I'll start with a longish quote that gives the gist of their analysis, and then follow with some comments of my own.

For Top Colleges, Economy Has Not Reduced Interest (or Made Getting in Easier)
"Representatives of Harvard, Stanford, Dartmouth, Yale, and Brown, among other highly selective institutions, said in telephone and e-mail exchanges in recent days that applications for the Class of 2013 had jumped sharply when compared to the previous year’s class. As a result, the percentage of applicants who will receive good news from the eight colleges of the Ivy League (and a few other top schools that send out decision letters this week) is expected to hover at – or near – record lows.
"Bill Fitzsimmons, dean of admissions and financial aid at Harvard since 1986, said that the 29,112 applications Harvard received this year represented an all-time high, and a 6-percentage point increase from last year. He said the percentage of applicants admitted would be 7 percent, down from 8 percent a year ago. Dartmouth said that the 18,130 applications it received was the most in its history, too, and that the 12 percent admitted would be its lowest.
"Stanford said that the 30,350 applications it received represented a 20 percent increase, and that while it estimated a 7.5-percent admission rate, which would be its lowest, it declined to specify a final figure until later in the week.
"Yale, Brown, Columbia, Cornell and Princeton declined to release their final admission rates in advance of sending out most of their decision letters via e-mail at 5 p.m. eastern time on Tuesday. But Brown said it had received 21 percent more applications, overall, compared to a year ago; Yale was up 14 percent; Columbia was up 13 percent and Cornell was up 3 percent. Princeton said that, as of January, it had tallied a 2 percent increase in applications, but anticipated the pool had gotten even larger since then. At the University of Pennsylvania, the number of applications increased by 4 — to 22,939, from 22,935.
"However, applications to highly selective colleges were not up universally. Many of the best-known liberal arts colleges had fewer applications this year."

The reduced applications to liberal arts colleges are probably good news for the high school seniors who made those applications. But it is much less clear that the increased numbers of applications to selective universities will be such good news for those universities (or quite such bad news as the story anticipates for their applicants). In particular, while there may be record numbers of high school graduates this year, it seems likely that they are also applying to more universities than they have in the past.

This may be recession related, as people look for more competing financial aid offers. But it may also just be everyone's reaction to being told by their high school guidance counsellor that this year may be unusually competitive, so that no one can count on getting in at the schools they traditionally expected to go to. That is, if everyone else is applying to more universities, and if additionally, in reaction, universities are going to admit a smaller percentage of applicants, then a rational response is to apply to more schools yourself.

But if this is the case, and if universities' preferences are correlated (as they must be, since they all like high grades and exam scores), then many universities will be admitting the same applicants. Since applicants can accept only one offer of admission, this may mean that the percentage of admitted students who accept their offers ("yield") will be unusually low for many elite universities. (Maybe not for Harvard.)

If that is the case, there should be an unusual number of admits from wait lists this year. Universities have likely prepared for this by putting lots of students on their wait lists. But still, there should be some movement on those lists this year.

So, if you are a high school senior on a wait list, stay cool.

Singapore kidney update

To follow up on my post yesterday about Organ donation and compensation in Singapore: new legislation, Sally Satel points me to The Human Organ Transplant (Amendment) Bill-Closing Speech by the Health Minister, Khaw Boon Wan.

It contains a number of points, not least of which is that the new legislation will legalize Kidney Exchange in Singapore. (It's interesting to note that they are thinking of legislating simultaneous exchange.) More interestingly, the speech elaborates on the manner in which the legislation is meant to continue to prohibit "organ trading," while allowing the reimbursement of donor expenses by the recipients.

All of this will make it interesting to see how procedures in Singapore evolve. Will willing donors become abundant, and will they thrive in the long term? Will the availability of compensation crowd out the familial donors who drive kidney exchange? Will it be possible to restrict payments to expenses and lost wages? As Jeff Ely noted yesterday in his post Organs for Money, "Whether or not the new laws truly legitimize organ sales, markets have a way of organizing themselves around and in-between the cracks of legislation."

Some excerpts from the speech (emphasis added):

"(II) Allow Paired Matching4. All supported the proposal to allow paired matching. Dr Fatimah called for the establishment of a “systematic, proactive and well-organised living donor registry” to support paired matching. I agree. The National Organ Transplant Unit of the Ministry of Health will take charge of this.
5. The same unit will also take charge of setting up a Donor Care Register to monitor the health of the donors. Mdm Halimah and some other Members are curious about the long term health of the living donors. If the donors are well selected, there is good medical evidence overseas to suggest that there are few adverse medical impacts. But there is little local research on this. The proposed register will help us track long-term clinical outcomes and allow us to better understand the long-term impact of organ donation, if any.
6. Prof Thio asked how “pair matched” organ transplants will be regulated. She noted that in other jurisdictions, the transplant surgeries are carried out simultaneously to avoid situations where one of the donors decides to back out. Dr Lim Wee Kiak stressed the need to carry out such procedures simultaneously. Indeed, this will be the requirement for paired matching, that the surgeries will all have to be done simultaneously. Our Bill includes provisions for subsidiary legislation to be made to regulate organ transplant arrangements, including mandating that paired transplants be simultaneously performed, if this is necessary. We can achieve such an outcome administratively since the operations are carried out in our hospitals, but we will study if there is a need for an explicit regulation."
...

"(III) Allow Payment for Living Donors
7. Let me now address the more controversial issue of payment for living donors.
Safeguards against Organ Trading
8. While all Members supported the good intention to reduce the financial losses incurred by donors through reasonable payment, Members were concerned that it might lead to organ trading, and Singapore becoming a regional organ trading hub. For example, Miss Sylvia Lim was concerned that the reimbursement value could become a backdoor to organ trading. During the public consultation stage, the World Health Organization and many Singaporeans expressed a similar concern.
9. Let me reiterate that this Bill does not legalise organ trading. During the public consultation, decriminalising organ trading and the Iranian model were often cited. But this Bill is not to legalise organ trading. Hence, Mdm Halimah’s concern about the Bill affecting Singapore’s relationship with its ASEAN neighbours does not arise. Our Bill in fact contains an amendment to raise the penalty on syndicates involved in organ trading. The Bill is to catch up with what many OECD countries have already done for many years. In drafting our amendments, we took reference from similar legislations in several of these countries. We are correcting our current extreme position of criminalizing all kinds of payment to the donor. For example, currently donors are charged by the hospitals for all their transplant-related medical and surgical expenses. The recipients are prevented by HOTA from reimbursing the donors for these expenses. The proposed amendments will bring us in line with jurisdictions such as the US and UK to allow some payments to be made to the donor.
10. Let me also clarify that we are not making it compulsory to reimburse living donors. We are merely allowing organ recipients, if they wish, to make some payment to cover the financial losses incurred by their donors. In fact, I will not be surprised if many living donors continue the current practice of not requiring any reimbursements from the recipients. This would address the concern of some members that low income recipients may not be able to afford such payment. But in the event that some donors may need such reimbursements and the recipients agree to do so, the law should not prevent it from happening.
11. I must also explain that reimbursement only applies to living donors. It does not apply to cadaveric donation where allocation of organs will continue to be based on tissue matching, time on the waiting list and other clinical factors as objectively determined by an expert committee. Hence the concern of Mdm Halimah and Mr de Souza about rich patients jumping the queue for the cadaveric organs does not arise. Indeed, as carefully pointed out by Mr Sam Tan, the Bill does not discriminate against the poor. Among living donors today, there is a mix of high and low income donors.
12. But as Members put it, the real challenge in donor reimbursement lies in the practical difficulties of making a distinction between what is reasonable payment and what is inducement. I agree with Members that the key lies with putting in place appropriate safeguards. ..."
...

"21. Some of the Members asked who would pay the donors. The organ recipients would make the payment. Some Members suggested that a third party should administer the payment. Some payments will indeed be via a third party. For example, reimbursement for hospital expenses incurred by the donor can be done via the hospital. But there will also be payments which are made directly between the donors and the recipients, without going through a third party. Mdm Halimah suggested that part of the payment can be made via the donor’s Medisave Account. I think it is a good idea, provided the CPF rule allows such a voluntary contribution. Mr Ang Mong Seng suggested having a trust to hold half of the money received by the donor to ensure that it is not frittered away. But such arrangements are best left to the donor and recipient to decide."

"Problem customer" registries for prostitutes

High end prostitutes and others who do business as "escorts" are vulnerable to booking bad customers, who may be abusive, fail to pay, be undercover police officers, insist on unsafe sex, or simply fail to keep their appointments. Because the services prostitutes sell are largely illegal, and because their customers may be anonymous, the market design problem of establishing a recommender/reputation feedback system to identify problem customers is considerable.

But there are several efforts in this direction, including sites which attempt to be available to the profession only (e.g. ProviderBuzz and DangerZone411), and, more accessibly, the National Blacklist Deadbeats Registry (Serving the Escorts Community)
"Our Vision: To see the day when female escorts (meaning; adult service providers, sex workers, call girls, courtesans, etc.) can work free from harm, and with peace of mind from pests, scammers, abusers, harassers, and stalkers."

The site (which requires a paid subscription to be able to search the reports) invites escorts to report and (try to) identify problem customers. The "incident report" form prompts the reporter for any available information identifying the customer (name, email address or phone number, "stated occupation," etc.), for a full physical description, and for a description of the incident, including an address (but with the warning "DO NOT put your address if the incident was at your incall location. You do not want to show YOUR address!")

Organ donation and compensation in Singapore: new legislation

A new law was passed on March 24 in Singapore, allowing compensation for live organ donation. It's not yet clear what this will mean in practice: I excerpt below from a number of stories.

Singapore allows payment for living organ donors
"After a heated two-day debate, in which some legislators raised concerns that the new law might lead to open organ trading, four of the 84 members of parliament abstained the final vote and one voted against, the Straits Times newspaper reported.
...
"Not all legislators were convinced, although Health Minister Khaw Boon Wan had assured parliament that the new law "is not to legalise organ trading."
"We are correcting our current extreme position of criminalising all kinds of payment to the donor," Khaw said.
Singapore already had a legal system to prevent organ trading, he said. "And we will be strengthening it," Khaw added.
The new law, which also contained some other changes, allows living organ donors to be reimbursed the costs for items like travel, accommodation, costs of domestic care and child care, loss of income and long-term medical care.
..
"Another dissenter, Halimah Yacob, said that many foreign workers in Singapore, who are hit hard by the recession, could become "a ready and vulnerable pool of organ donors to be exploited and abused.""To a desperate foreign worker, even a reimbursement of S$10,000 would be attractive compared to going home empty-handed with a huge debt waiting for him," the report quoted her as saying.
The Singapore government proposed to change the law after ailing retail magnate Tang Wee Sung was jailed for a day and fined S$17,000 in June last year for trying to buy a kidney from an Indonesian donor.Tang finally received a kidney from former organised crime boss Tan Chor Jin, who was hanged in a Singapore prison in December for the killing of a nightclub owner."

A tough moral choice : Slew of safeguards promised as MPs approve recompense for organ donors, though five remain unconvinced.
"IT WAS a moral dilemma Health Minister Khaw Boon Wan apologised for imposing on Members of Parliament, after two days of intense debate.
Their tough choice: Should they correct the unfairness against: altruistic organ donors by allowing them reimbursement for their financial losses, but at the risk of opening a backdoor for abuse? "

Singapore allows financial payment to organ donors
"Previously, it was illegal for a living donor to be financially compensated but the issue came to a head last year when a local tycoon was jailed for one day for attempting to pay off a prospective Indonesian kidney donor.
"This is a bill about fairness, being fair to donors who do suffer financial consequences as a result of their act of donation," Health Minister Khaw Boon Wan told parliament Tuesday during the final debate on the issue.
"I know the controversial nature of paying donors," Khaw said. "But we also realise that it is unfair to allow genuine donors to bear all the financial consequences of their altruistic acts."
Khaw said he disagreed with the suggestion made by some lawmakers that foreign donors be barred from accepting financial compensation to prevent exploitation of nationals from poor countries.
"How can we discriminate against the foreign donors in this fashion?" Khaw said.
"Once we decide that some payments can be ethically made, our law cannot unfairly discriminate against organ donors based on their nationalities," he said."

Singapore's Human Organ Transplant Act dates from 1986, when it instituted an opt-out system for all of the country's non-Muslim citizens. Under the law, citizens could opt out of becoming organ donors, but all those who did not would be considered as organ donors upon their death, and would in turn receive priority (over those who opted out) for receiving deceased organs. Unusually among countries with opt out policies, organ donation has been enforced even over the objections of next of kin.
As amended in January 2008, the Human Organ Transplant Act (HOTA) now includes Muslim citizens of Singapore.

Giving anonymously, for a fee

How to give money to a friend anonymously (and be sure that it is received)? Try Giving Anonymously, established "to facilitate giving in such a way that "money" does not hinder friendship." They will send along your gift via their own check, and send you a copy of the cancelled check.

Anonymity when giving charity has a long history. It plays a big role in Jewish thought, for example, as codified by the 12th century scholar Rabbi Moshe ben Maimon (aka Maimonides, or the Rambam).

When looking at repugnant transactions, often the addition of money is what arouses repugnance (e.g. kidney donations don't arouse the repugnance of kidney sales). Something like that seems to be at work here; you might like to give someone a gift, they might need and want one, but the complications of giving and receiving money from a friend might prevent an otherwise mutually desired transaction from going through.

What is the price of anonymity? Doing it through this particular anonymizing service costs $2.50 + 2.5% of your gift.

Update (and sign of the hard times): Today's Boston Globe has a story on a related theme: Colleagues pitch in to ease the pain.
"As the economic downturn persists, specialists who follow workplace trends say more employees are trying to save colleagues' jobs through voluntary pay cuts or freezes, furloughs, and donations. "

Markets for (viewing) bodies

Among the oldest repugnant transactions are those that involve dealing with the dead. In the early 1800's, British medical schools illegally purchased cadavers for anatomy classes from grave robbers called "resurrection men," because the only cadavers legally available for dissection were the bodies of executed murderers. (The Harvard Medical School is in Boston rather than Cambridge, I understand, because of an arrangement offered by the city of Boston to supply unclaimed cadavers.) But those constraints have been relaxed over time, and in my 2007 paper Repugnance as a Constraint on Markets, I used as an example the "Bodyworlds" museum shows that tour the world, allowing museum goers to see cadavers (posed as if engaged in lifetime activities) in detail previously available only to medical students (and here is an essay on the value of that experience to medical students: Dead Body of Knowledge).

But while the laws governing the trade in corpses have been relaxed, there remain considerable feelings of repugnance about desecrating corpses, and these museum shows have also aroused opposition. The latest news is that such a show is planned as a travelling exhibit in Israel. Judaism has strong norms about respect for the dead, and it seems likely that there will be considerable controversy: Controversial 'Body Worlds' exhibit based on preserved human bodies scheduled to arrive in Israel next month. Various religious body gearing up for battle against show, arguing it violates the dignity of the dead .

(Meanwhile, elsewhere in the Middle East, the tensions between secular and religious, ancient and modern, is of a very different sort:
Hardline Saudi Clerics Urge TV Ban on Women, Music.
" ''No Saudi women should appear on TV, no matter what the reason,'' the statement said. ''No images of women should appear in Saudi newspapers and magazines.'' ")

Google's auction for TV ads (and some thoughts on Practice and Theory)

Noam Nisan at Algorithmic Game Theory posts a preliminary version of his paper Google's auction for TV ads.

It is part of a post titled AGT and practice, which is worth reading along with the paper. In the paper, Nisan and his coauthors first describe the Google system and some of its requirements, then outline a (too) simple model (an ascending auction of the Demange, Gale, Sotomayor line), and then discuss ways in which the model is too simple.

All of this made me think of writing a post sometime called "Practice and Theory." I don't know that I have enough to say on that right now, but the main idea would be to reflect on some of the ways that market design, and the theoretical work that supports it, differ from traditional (theoretical) game theory.

In a traditional theory paper, a problem is presented, along with a model of that problem, and an exact solution. Producing such a paper is a bit like finding a fixed point: in the course of proving the theorem, it may be necessary to adjust the model, and the statement of the theorem, and perhaps the definition of the problem, in order that the parts all fit together properly.

In a market design paper, in contrast, the problem and to a large extent the model may be fixed in advance, and so what has to be adjusted is the solution. Sometimes an exact solution can't be found (perhaps an impossibility theorem shows that there is no exact solution), and instead some sort of approximate solution is found. Traditional theorists sometimes look at the results and say that they don't look like a good theory paper, which should find an exact solution. Part of our job as market designers, and theorists who do market design, is to help explain this difference.

Update on scalping

My old friend the sports economist Larry DeBrock writes to update my recent post on Scalping and intermediation:

"...the Cubs won a big lawsuit in 2003 after they set up a wholly separate firm “Premium Ticket Services” and transferred GREAT seats to them before opening tickets to the general public. They made some tremendous markups (reported to be 30 times face) on these seats.
Attached is the law review paper about this case.
Jasmin Yang, A Whole Different Ballgame: Ticket Scalping Legislation and Behavioral Economics?, 7 VAND. J. ENT. L. & PRAC. 111, 111 (2004)."

I can't resist adding that, long, long before Larry became Dean of the College of Business at the University of Illinois in Urbana Champaign (so long ago that it was still called the College of Commerce, and the Rand Journal was still the Bell Journal), he coauthored what I always hoped would become the definitive paper on strikes in major league baseball.

Market for book reviews: Amazon version

Here's a nice description of how Amazon's reviews are ordered: at the top are the ones rated most useful, both positive and negative: The Magic Behind Amazon's 2.7 Billion Dollar Question

"Even the behavior of clicking Yes or No is elegant. Amazon tracks who rates each review as helpful, allowing each person to only vote once. This prevents "gaming the system" by voting for a friend's (or your own) review multiple times. Clicking either Yes or No pops up a quick message, saying the vote will take effect within 24 hours. (This delay also reduces gaming.)
Amazon quietly bumps the three most helpful reviews to the top. It tries to balance positive and negative reviews, so shoppers get a balanced perspective. An interesting side effect is how these selected reviews get more votes. If they are controversial (in that not everyone agrees they were helpful), their ratio goes down, allowing the most helpful reviews to bubble up past them."

And here is a discussion of how online recommendation systems might decrease the total diversity of products: Online Monoculture and the End of the Niche (HT to MR)

Algorithmic Game Theory blog

Noam Nisan the eminent Hebrew University computer scientist, has a new blog, called Algorithmic Game Theory.

For economists who may not yet know, Nisan is one of the pioneers on the interface of computer science, game theory, and economics. He's also one of the editors of the book Algorithmic Game Theory, and the advisor of a host of students and postdocs whose work we are going to need to be familiar with as the connections between CS and Econ grow closer.

''Not everything that is immoral has to be illegal'

The quotation in the title of this post is from Romanian Justice Ministry legal expert Valerian Cioclei, and it comes from the NY Times story Romania Weighs Decriminalizing Consensual Incest .

"Three European Union nations -- France, Spain and Portugal -- do not prosecute consenting adults for incest, and Romania is considering following suit.
...
"Incest is defined as sexual intercourse between people too closely related to marry legally. In the United States, all 50 states and the District of Columbia prohibit even consensual incest, although a few states impose no criminal penalties for it..."

Incest is surely one of the prototypical repugnant transactions, namely one that people don't like to have others engage in. Such repugnance is often reflected in law, but by no means always. (E.g. there is no law against going to the front of a long line at the supermarket checkout counter and asking a person near the front to sell you their spot, i.e. to move to the back of the line and let you into their place in return for a cash payment. But here's a story of an economist , Oz Brownlee, who, after trying to do that, decided that the best course of action was to leave the store without buying anything.)

A famous article by Jonathan Haidt (Haidt, J. (2001). The emotional dog and its rational tail: A social intuitionist approach to moral judgment. Psychological Review. 108, 814-834 ) begins with an example of consensual incest.
"Julie and Mark are brother and sister. They are traveling together in France on summer vacation from college. One night they are staying alone in a cabin near the beach. They decide that it would be interesting and fun if they tried making love. At very least it would be a new experience for each of them. Julie was already taking birth control pills, but Mark uses a condom too, just to be safe. They both enjoy making love, but they decide not to do it again. They keep that night as a special secret, which makes
them feel even closer to each other.
What do you think about that, was it OK for them to make love?

"Most people who hear the above story immediately say that it was wrong for the siblings to make love, and they then set about searching for reasons (Haidt, Bjorklund, & Murphy, 2000). They point out the dangers of inbreeding, only to remember that Julie and Mark used two forms of birth control. They argue that Julie and Mark will be hurt, perhaps emotionally, even though the story makes it clear that no harm befell them. Eventually,
many people say something like “I don’t know, I can’t explain it, I just know it’s wrong.” But what model of moral judgment allows a person to know that something was wrong, without knowing why?"

Haidt (and colleagues, particularly Paul Rozin) have studied the emotion of disgust, and think that a lot of moral judgements may be mediated by the disgust reaction (whose initial evolutionary significance is presumably to prevent us from eating spoiled food, etc.). This makes a lot of sense for incest (because evolution should help us avoid inbreeding, with the excessive concentration of recessive genes in offspring).

I suspect that many of the more clearly economic transactions that are or have been regarded as repugnant are less closely tied to hard-wired disgust. That is not to say that, as people who are culturally acclimated to find some kind of transaction repugnant (e.g. charging interest on loans was repugnant for centuries in Europe), we may not be able to recruit our disgust reaction to make sense of things we disapprove of. Just as not every repugnant transaction is against the law, they may not all originate with (or even activate in a secondary manner) feelings of disgust. (See my other posts on repugnant transactions for a variety of examples...)

Update: see an article on disgust and moral judgement in the March 2009 issue of The Jury Expert (a very task oriented journal focused on picking and persuading jurors): Grime and Punishment: How Disgust Influences Moral, Social and Legal judgments

School choice in Belgium: update

In an earlier post, I discussed some of the problems in the school choice systems in Belgium, and noted that Estelle Cantillon had organized a conference on the subject in Brussels in January.

Estelle's conference has had some effect. She writes "The parliament of the French-speaking Community will adopt tomorrow a new school enrollment decree. The article says that it will be centralized (coordination among networks), that parents will be asked for their preferences, ... The details will be worked out after the elections in June. " Inscriptions: un nouveau décret, trois mesures

Economics Job Market “Scramble” for New Ph.D.s

To candidates on the economics job market (and to graduate placement directors): the scramble opens for registration tomorrow (March 24), and is open one week only (registration closes on March 30). There's no special benefit to registering on the very first day, but if you haven't registered by the last day you can't participate, so, if you're planning to register, don't wait til the last day (behavioral economist's advice).

The back story on this is that new Ph.D.s in economics have been busy since the first days of the year interviewing for jobs. The first stage of the interviewing process was at the annual professional meetings in early January. For jobs at universities, the latter stage of the interviewing process involves "flyouts," campus visits at which the candidate meets the faculty, and gives a research seminar or teaching demonstration, or sometimes both. While many jobs have been filled by now, there are both candidates and jobs still available. Many of the still unmatched candidates and still unfilled jobs are already engaged with each other in the courtship process, and are slowly working towards offers and acceptances. However there are also people and jobs still available who failed to connect with each other in the earlier parts of the market.

To make it easier for people and jobs to connect at this late stage of the market, the American Economic Association's Ad Hoc Committee on the Job Market* started a simple "scramble" in the 2005-06 academic year. It is a pair of web pages on which candidates and jobs can list their continued availability. See the Scramble Guide for details. This year's scramble opens tomorrow, March 24, and stays open for registration for a week. After that it becomes visible to registered participants on both sides of the market.

It doesn't attempt to do any more than make the two sides of the market more visible to each other, and after two weeks it closes. Once registration closes on March 30, the site is passive, it isn't updated. It is up to candidates and jobs to contact each other.

There is one new feature this year, which I'm slightly ambivalent about. Some departments that entered the scramble last year complained that they were overwhelmed by the large number of new applications they received. Faced with the threat of employers declining to participate in the scramble, the Committee decided to allow employers to register but withhold their information from job candidates. So this year there will be some "invisible" employers registered for the scramble, who will be able to see the candidates and contact those they wish, but whose own contact information will not be available.

So far, the scramble hasn't been a giant part of the market; most jobs have (fortunately) been arranged earlier, through the regular process. Last year, in the 2008 scramble (following the 2007-08 job market) 100 employers and 361 applicants registered. We conducted a followup survey of employers and received 30 replies. Of those employers who responded, 22 contacted people in the scramble, 19 interviewed someone from the scramble, and 10 hired someone from the scramble (one hired two people from the scramble) . 17 of the 22 respondents who contacted applicants in the scramble were academic economics departments, as were 8 of the 10 respondents who reported hiring through the scramble.

Every economist is important. Good luck to those still on the job market.

To summarize. 2009 Job Market Scramble Important Dates:
March 24: Registration Opens
March 30: Registration Closes
April 1 : Scramble Website will open for viewing by registered participants only
April 11: Scramble Viewing will close

The Harvard of Auctioneering

I was struck by this line in a story in the NY Times:
"The auction itself began at 10:15 a.m. when Rob Nord, a professor of bid calling at the Missouri Auction School (“The Harvard of Auctioneering”), started with Lot 1: four diamonds varying in weight from 1.1 to 1.4 carats."

Here is the story: Selling the Diamonds the Government Doesn’t Need , which is about how the US government sells off items seized in the course of federal crimes, and, lately, acquired by the government in other ways.
"Mr. Levin, who, on average, takes a 10 percent cut from his auctions, has been very busy of late. In the last few years alone, he has sold for the government smuggled horses in Arizona, stolen cab medallions in Boston, 54,000 pounds of smoked Chinese scallops, a shipping container of blue jeans, illegally marketed Freon and a million packs of untaxed cigarettes.
"Tapping what could be a growing market, Mr. Levin recently secured a contract with the Federal Deposit Insurance Corporation to auction furniture, fixtures and equipment seized from failed banks around the country."

And here is the website of the Missouri Auction School, which does indeed mention that it is called the "Harvard of Auctioneering." Here are some sentences from the description of their course (I have always thought that the different chants used by auctioneers of different products in different places would be worth study):
"The classroom portion includes small group sessions learning the auction chant from leading auctioneers from around the country. It also includes those top auctioneers sharing business insights and secrets with the entire class."

Market for childrens' books

Bestsellers in any category are what make publishing profitable. But childrens' books must be very special, because a bestseller can have high sales for a long time, as new generations of the target audience are born. I've always thought that this must be especially true for those books made of thick cardboard, suitable for chewing on as well as reading, since each new reader needs a new copy (chewing cuts down on the used book/hand me down market). But I hadn't guessed just how big the revenue stream is.

Both of my children enjoyed "The Very Hungry Caterpillar," which celebrates its 40th birthday this week: Happy birthday, hungry caterpillar!

" 'The Very Hungry Caterpillar,' who eats his way through the book, leaving a trail of holes behind, has sold 29 million copies and has licensing deals, Newsweek reports, of $50 million annually. With the money, Carle established the Eric Carle Museum of Picture Book Art in Amherst, Mass.; its exhibits have celebrated works by Dorothy Kunhardt ("Pat the Bunny"), Arnold Lobel ("Frog and Toad") and Maurice Sendak ("Where the Wild Things Are"). "

Scalping and intermediation

The resale of tickets for concerts and sporting events, at higher prices than those at which they were initially made available, is often regarded as "scalping," a repugnant transaction that is illegal in some states. (See e.g. Greg Mankiw's post about resales of Jay Leno tickets...)

But the lines are getting less clear, as artists and sporting venues try to make use of the secondary market themselves, to benefit from the higher prices enabled by discriminatory pricing:
Concert Tickets Get Set Aside, Marked Up by Artists, Managers .

"Less than a minute after tickets for last August's Neil Diamond concerts at New York's Madison Square Garden went on sale, more than 100 seats were available for hundreds of dollars more than their normal face value on premium-ticket site TicketExchange.com. The seller? Neil Diamond."

..."Secondary ticket sales are viewed by Ticketmaster, concert promoters and artists as one of the biggest -- yet thorniest -- sources for revenue gains. In 2006, Ticketmaster launched TicketExchange in response to pressure put on its profit margins by secondary-ticket sellers such as StubHub. But in doing so, it opened the company to criticism by ticket brokers, fans and politicians, who accuse the ticketing giant of profiteering and obfuscation.
Ticketmaster is moving to distance itself from some parts of the secondary ticketing market. It is in the process of hiring an investment bank to try to sell another resale service, TicketsNow, according to people familiar with the matter.
Virtually every major concert tour today involves some official tickets that are priced and sold as if they were offered for resale by fans or brokers, but that are set aside by the artists and promoters, according to a number of people involved in the sales."

One of the interesting things about this story is how Ticketmaster and the artists seek to put some distance between themselves and the secondary market. Luke Coffman (who you can try to hire next year), has a paper that seeks to understand this: Intermediation Reduces Punishment .

As part of his investigation into how people view economic transactions, he runs experiments that show that charging a high price through an intermediary may be seen as less blameworthy than charging a high price directly, even if going through an intermediary means that the ultimate price charged is higher than it would have been with a direct sale. And, he finds, this doesn't seem to result from confusion; apparently putting some distance between yourself and an act that may be regarded as blameworthy dilutes the blame, even in the eyes of observers who understand that you are doing it for that reason.

The "middleman" view of scalping gets some support from Trent Reznor of the band Nine Inch Nails (courtesy of Eric Crampton's blog Offsetting Behavior, for which HT to MR).

Luke will be talking about his work on intermediation, and related work on how people perceive the moral content of economic transactions, in our Experimental Economics class today.

Match Day for new doctors

Today is the third Thursday in March, Match Day for young doctors seeking their first job through the National Resident Matching Program (NRMP).

Here is the NRMP press release. Almost 30,000 applicants (11,000 from foreign medical schools) sought the 22,427 first year positions available in this year's match. About 95% of the available positions were filled through the match, the rest are filled in a post-match "scramble." (The organization of the scramble is under discussion, and here's the WSJ's account of it.)

The NY Times covers match day with a story and a picture: A Medical Student’s Rite of Passage . As in many discussions of labor markets, the author finds that many medical students wish they had more control over where they are going. Some of them attribute this loss of control to the match process, while others know something about how the medical market worked before the match. (Among the online comments on the story is this one:
"I wish they did something like this for law students. The job experiences and training available to new lawyers are extremely uneven. Plus it is on the law student to secure that first job on the open market, with no real guarantees of getting hired."

There's a new book by Brian Eule, Match Day: One Day and One Dramatic Year in the Lives of Three New Doctors, that follows three women through the match, one of them now his wife. I haven't seen the book yet, but I talked to him a number of times while he was writing it, and he once gamely sat through a lecture in my Market Design class.

788 couples went through the match this year as couples (some others may go through without identifying themselves that way, and the NY Times story remarks that some were disappointed not to have gotten jobs together). For the technically inclined, here's an account of how the new couples algorithm works to allow couples to express their preferences over pairs of jobs (and of the design process that led to the new match algorithm that's been in use since 1998):

Black market kidney sales in the Phillipines

Last Friday I was part of a panel at Harvard at the National Undergraduate Bioethics Conference , at which a panel consisting of me, Frank Delmonico, and Nir Eyal, and moderated by Dan Brock, was asked to consider the question "Should willing sellers be permitted to sell body parts to willing buyers?".

Among other things, I defended the point that the performance of a potentially regulated legal market can’t be well predicted from the performance of unregulated, illegal markets. Frank largely disagrees with that, and expects that any regulation short of attempting to ban organ markets outright will inevitably deteriorate into the kinds of illegal markets we see in some parts of the developing world. Regardless, it's good to pay attention to the black and grey markets around the world. Here's an account of such a market in the Phillipines: No Turning Back. Some aspects of this market are quite black (the subject of the story is threatened with retribution if he changes his mind once medical tests have been paid for), and some are grey (quite a few medical tests are done, although perhaps not to the standard we would like), and some are not even so grey (the subject of the story is paid, and gets a motor vehicle and a house out of it, and would do it again).

"Lito, 23, a resident of Gumaca, Quezon, who sold one of his kidneys, knew the stakes just got higher when he was told before the transplant procedure that he could not back out anymore. A friend of his decided to pull-out. “They are hunting him down. They want to have him killed." ... "On February 14, 2007, the friend accompanied Lito to a house in Barangay Tikalan, a village in San Juan, Batangas where a man named “Junior” who was referred to by his men as the “manager,” housed other would-be donors.“Junior” is also an organ donor. The following day, Lito and nine others were brought to a private hospital laboratory in front of the National Kidney and Transplant Institute (NKTI) where many people were having their blood samples taken. They also underwent a number of tests. X-rays were also taken. Junior paid for the procedures. " ... "For over a month after the first tests, Lito shuttled back and forth from Batangas to Metro Manila in order to undergo various tests in different hospitals. In each of the trips, he was accompanied by either “Junior” or one of his men. The purpose, he was told, was to look for a match. ... "Back home in Gumaca, Lito found that money has a way of slipping easily between one’s fingers. In his case, it lasted only for six months. Almost half of the amount he got from selling his kidney—about P40,000—went to the payment of debts. With the rest of the money he was able to buy a tricycle and a small dwelling. Months later, however, he had to pawn the tricycle to pay for his daughter’s hospitalization. Lito does not regret going through the operation. “I was in dire straits,” he explained. If he did not go through it, he said, he would not have been able to pay his debts. Besides, he said, he did it for his family’s sake. “I am ready to give up my life, for the sake of my family.” "

Market for information

Mostly we think it is good for information to be freely available, but one place where we often do not is in the adversarial system of trial by jury. The rules of evidence permit judges to decide what evidence is admissable, and what is not. I have served on juries in which we were instructed not to read news accounts of the trial we were part of. Sometimes juries are sequestered, so that they cannot have much contact with the outside world. That has all gotten a little harder to enforce, now that everyone has Google in their pocket: Mistrial by iPhone: Juries’ Web Research Upends Trials .

"Last week, a juror in a big federal drug trial in Florida admitted to the judge that he had been doing research on the case on the Internet, directly violating the judge’s instructions and centuries of legal rules. But when the judge questioned the rest of the jury, he got an even bigger shock.
Eight other jurors had been doing the same thing. The federal judge, William J. Zloch, had no choice but to declare a mistrial, wasting eight weeks of work by federal prosecutors and defense lawyers."
