Match Day!

This year's schedule for announcing the results of the resident match ends today, when most graduating medical students will learn where they have been matched.

Over the last few days, those who were not matched in the main match learned of this, so that they could "scramble" to match by the time that their colleagues would learn of their matches.

Here's this year's schedule:

March 15, 2010--Applicant matched and unmatched information posted to the Web site at 12:00 noon eastern time.
March 16, 2010--Filled and unfilled results for individual programs posted to the Web site at 11:30 a.m. eastern time.
Locations of all unfilled positions are released at 12:00 noon eastern time. Unmatched applicants may begin contacting unfilled programs at 12:00 noon eastern time.
March 18, 2010--Match Day! Match results for applicants are posted to Web site at 1:00 pm eastern time.

Next year this will all play out differently, since the NRMP has decided to organize a "managed scramble":

"The NRMP Board of Directors has voted to proceed with implementation of a "managed" Scramble for the 2012 Main Residency Match. Under the plan, unfilled positions must be offered and accepted through the NRMP R3 System during Match Week. Offers will be made every three hours Wednesday - Friday of Match Week, and applicants will be able to receive multiple simultaneous offers. Match Day will be moved from Thursday to Friday. Questions should be directed to nrmp@aamc.org."

Right now there is pressure on the number of residencies that can be funded, so there may not be as much problem with congestion as would otherwise be a concern. We'll have to wait until next year to find out. (I wasn't involved in this latest design discussion.)

Who would sell kidneys, if kidney sales were legal?

Not just the poor, according to a new (and sure to be controversial) study conducted by interviewing people at regional rail and urban trolley lines near Philadelphia.

The Annals of Internal Medicine has just published an article
Regulated Payments for Living Kidney Donation: An Empirical Assessment of the Ethical Concerns by Scott D. Halpern, Amelie Raz, Rachel Kohn, Michael Rey, David A. Asch, and Peter Reese.

It finds: "...participants' willingness to donate increased significantly as their risk for kidney failure decreased, as the payment offered increased, and when the kidney recipient was a family member rather than a patient on a public waiting list (P [lessthan] 0.001 for each). No statistical interactions were identified ...between payment and income (odds ratio, 1.01 [CI, 0.99 to 1.03]). The proximity of these estimates to 1.0 and narrowness of the CIs suggest that payment is neither an undue nor an unjust inducement, respectively. Alerting participants to the possibility of payment did not alter their willingness to donate for altruistic reasons (P = 0.40). "

The lead author, Scott Halpern, is at Penn, affiliated with the Center for Health Incentives.

Wiseguy Tickets

If I were planning to break the laws on ticket resales, I think I would refrain from calling my company Wiseguy Tickts: 4 Charged in Concert Ticket Resale Scheme

"Federal prosecutors in New Jersey said on Monday that four men operating under the name Wiseguy Tickets had broken into online sites, buying more than one million tickets to some of the country’s most popular musical and sporting events and then reselling them for more than $25 million in profit.
In its 43-count indictment, the prosecutors say the men built a computer network that created thousands of fake accounts and built a program that could outsmart the ticketing software that creates oddly shaped letters intended to require human verification.
The events affected by the scheme cut across a wide swath of the entertainment business, from Hannah Montana concerts to Broadway shows and New York Yankees playoff games. The verification systems of many major online ticket vendors, including Ticketmaster, Telecharge and Major League Baseball, were breached."

B2B finance

Page 14 of a recent report by Morgan Stanley focuses on The Receivables Exchange, about which I have posted previously. (The Morgan Stanley report emphasizes: " This is not a research report and was not prepared by Morgan Stanley research department. It was prepared by Morgan Stanley sales, trading, banking and other non-research personnel. Past performance is not necessarily a guide to future performance.") Here it is.

The report has some recent performance statistics, and says "The Receivables Exchange, a private company, started trading on November 18, 2008 to bring private capital to the market for SME [small/medium enterprise] credit. Via The Receivables Exchange, an SME can auction its receivables to the highest bidder(s) for a substantial advance rate. The Receivables Exchange provides straight-through processing and acts as collateral agent and servicer, using an innovative approach to mitigate default risk."

Here are my previous posts about the Receivables Exchange, which strikes me as quite an interesting venture in disintermediation of credit. (Full disclosure; I'm on their advisory board.)

New clearinghouse for new doctors in Scotland

There have been some changes in the SCOTTISH FOUNDATION ALLOCATION SCHEME, the program that matches new medical graduates to their first positions (which would be called residencies in the US) in Scotland.

Two features stand out in comparison to the American system (the NRMP).

First, employers may not submit preferences, but rather are all constrained to rank potential employees by their exam scores.

Second, couples cannot submit preferences over pairs of positions. Instead, each member of the couple submits a rank ordering of individual positions, and the algorithm combines these into a joint preference over pairs that is a function of the submitted rank order list and a table of compatibilities of positions.

"To accommodate linked applicants, a joint preference list is formed for each such pair, using their individual preference lists and the programme compatibility information. If such a pair, a and b, have individual preferences p1, p2, . . . , p10 and q1, q2, . . . , q10 respectively (with a the higher scoring applicant), then the joint preference list of the pair (a,b) is (p1,q1), (p1,q2), (p2,q1), (p2,q2), (p1,q3), (p3,q1), (p2,q3), (p3,q2), . . ., (p9,q10), (p10,q9), (p10,q10) (except that incompatible pairs of programmes are omitted)
In the main body of the algorithm, the members of a linked pair are handled together, so the match of the pair (a,b) to the programmes (p,q) will be accepted only if each of these programmes either has an unfilled place or a lower scoring applicant who can be displaced. A complication arises when one member x of a linked pair has to be withdrawn from a programme p because his/her partner was displaced from their current assigned programme. In this case, some other applicants may have been rejected by p because of the presence of x, and any such applicant a must be withdrawn from their current programme, if any, and have their best achievable preference reset to p. (A corresponding, but more complex reset operation is needed if a is a member of a linked pair). This reset operation thereby allows a further opportunity for applicant a to be matched to programme p.
The algorithm terminates when every single applicant and linked pair is either matched or has been rejected by, or displaced from, every entry in their preference list with no possibility of reconsideration by a programme that has had a withdrawal.
The final matching is stable for single applicants, as before, but also for linked pairs, in the sense that:
there can be no linked pair (a,b) of applicants who would prefer to be matched to compatible programmes (p,q), and at the same time, each of p and q has an unfilled place or an assigned applicant with a lower score than a and b respectively."

New school choice system in San Francisco

Board Approves New Student Assignment System for San Francisco Schools (now here)

Most of the last minute discussion was about what priorities different kinds of students will have at different kinds of schools. That is something that is likely to be adjusted from year to year. But the nice thing is that the underlying choice architecture will make it safe for parents to state their true preferences however the priorities are adjusted.

From the press release: "The choice algorithm was designed with the help of a volunteer team of market design experts who have previously been involved in designing choice algorithms for school choice in Boston and New York City. Volunteers from four prominent universities contributed to the effort, including Clayton Featherstone and Muriel Niederle of Stanford University, Atila Abdulkadiroglu of Duke University, Parag Pathak of MIT, and Alvin Roth of Harvard.
“We are pleased that the district has decided to adopt a choice architecture that makes it safe for parents to concentrate their effort on determining which schools they prefer, with confidence that they won’t hurt their chances by listing their preferences truthfully,” said Niederle and Featherstone, the Stanford research team."

Here are Rachel Norton's comments (she's a school board member with a blog), and here's the story from the SF Chronicle. Here are some of my recent posts on school choice; many of the recent ones tell the SF story as it unfolded.

Now, on to implementation.

Raffle for a human egg

The Times of London reports: IVF doctors to raffle human egg

"A FERTILITY clinic is raffling a human egg in London to promote its new “baby profiling” service, which circumvents British IVF (in vitro fertilisation) laws.
The winner will be able to pick the egg donor by racial background, upbringing and education. Payment for profit is illegal in Britain, but the £13,000 of free IVF treatment will be provided in America. "
...
"The eggs are provided by American donors aged between 19 and 32, all of whom are university students or graduates. Overweight women or smokers are not accepted onto the donation programme Before picking a donor, the British women scan detailed anonymised profiles, including the donors’ motives for selling. The profiles include recordings of the women talking about their attitudes, as well as pictures taken of them in their childhood. They only provide an up-to-date photo if they enter serious negotiations.
Women egg donors in America can make $10,000 (£6,600) a time if they are well educated and with desirable physical characteristics.
The sale of their eggs was condemned yesterday by Josephine Quintavalle, founder of Comment on Reproductive Ethics, a pressure group, who said the infertility market had plumbed new depths.
“In no other branch of medicine would the ruthless exploitation of the vulnerable be tolerated. These women selling their eggs are taking a huge risk with their health and future fertility simply because they need the money.”
In Britain, donors have to agree to be identified and contacted by any resulting offspring when they reach the age of 18.
Payments are restricted to a maximum fee of £250 for expenses, and as a result donors are in extremely short supply. "
...
"The lure of payment means there is no shortage of would-be egg donors in America. GIVF receives up to 500 applications a month, but only about five will pass the two-month screening programme. "
...
"In Britain, only 956 of the 36,861 women who had IVF in 2007 received donor eggs. Half of those were egg sharers and of the remainder many were friends or relatives of the women being treated.
The number of donors is boosted by an arrangement whereby women receive free treatment if they agree to share their eggs with another patient who has no useable eggs at all. The drawback is that anyone undergoing fertility treatment necessarily has inferior eggs, so the chances of pregnancy for both women is relatively poor.
Egg donation is a protracted and painful process that requires treatment with potentially dangerous drugs. A donor has to undergo a course of treatment aimed at stimulating her ovaries to produce a dozen or more eggs in one menstrual cycle, instead of the single ripe egg released every month in natural conditions.
Bridge Centre staff admit they were bemused by the GIVF free egg offer from America. “They are much more market-driven than we are, and they do have some rather more creative techniques,” said Michael Summers, a senior consultant in reproductive medicine at the Bridge."

The debate over whether it's ok for women to sell eggs is not over in America. Kim Krawiec at Faculty Lounge asks How Is An Egg Donor Like A Prostitute?
"A few weeks ago, House Bill 3077, which would make it illegal to compensate women for oocyte donation, easily passed the Oklahoma house by a vote of 85-8. Said Rep. Rebecca Hamilton, D-Oklahoma City, the bill’s author, fertility clinics "could use donor eggs all they want; they just can’t go out and solicit women with money.” According to news reports, Hamilton has likened the practice to prostitution, claiming that “it turns doctors into predators.”
The debate harkens back to an exchange in September, in which Dr. Naomi Pfeffer drew fire for a statement to the Motherhood in the 21st Century Conference at the University College London that compared egg donors to prostitutes. As reported in The Times:
British couples who travel abroad for IVF treatment and buy other women’s eggs are engaging in a form of prostitution, a fertility conference was told yesterday. . .
Professor Pfeffer, who researches controversial developments in medicine, told the Motherhood in the 21st Century Conference at University College London: “The exchange relationship is analogous to that of a client and a prostitute. It’s a unique situation because it’s the only instance in which a woman exploits another woman’s body….
These women are being encouraged to take real risks with their health through ovarian stimulation and egg retrieval. It commodifies women’s bodies and treats their reproductive capacities as a service.
So, what sort of crazy person would compare an egg donor to a prostitute?
I would. But not for the reasons that either Hamilton or Pfeffer have in mind.
As I argue in the recently posted, A Woman’s Worth, an egg donor is much like a prostitute in the following sense: both are selling something that is often expected or encouraged to be given for free or at a reduced price, despite its high economic value. "

School choice in Britain

A story in the Telegraph appears to report the remarkable fact that some schools in Britain are more popular than others, and are over-demanded: School admissions: half lose out in some areas
"Half of children in some areas have been rejected from their preferred secondary school amid fierce competition for the most sought-after places. "
...
"In Birmingham, only two-third of children gained places in their preferred school, a fall compared with last year.
The squeeze on places has led some over-subscribed schools to run controversial “lotteries” in which names are effectively picked from a hat.
The system is employed to stop middle-class parents jumping the queue for the best schools by buying homes in the catchment area.
Lotteries are believed to be used in at least one school in a third of local authorities. Hertfordshire council told the Telegraph yesterday that seven schools had employed the system.
Michael Gove, shadow schools secretary, said: “Unfortunately too often too many parents don’t get the school they want. The reality is that it is only the rich who can guarantee the kind of education they want for their children.” "

Elliott Spitzer on government’s role in the market

Government’s proper role in the market, in the Boston Review.

Spitzer writes from the point of view of a former Attorney General of New York (as opposed to real estate heir, former Governor, or Greek tragedian).

"To sum up, I want to leave you with ten points:
• Only government can enforce integrity and transparency in the marketplace; self-regulation is a failure.
• Only government can take necessary steps to overcome market failures, such as negative externalities or monopoly power.
• Only government can act to preserve certain core values in the market, such as prohibitions on discrimination.
• Too-big-to-fail is too-big-not-to-fail.
• We’re suffering from the Peter Principle on Steroids, and it will get us into deeper trouble.
• Taxpayers have been getting the short end of the stick in everything we’ve been doing. The Treasury Department is not negotiating for us.
• Risk is real, and no complex scheme of financial instruments can make it go away.
• We have de-leveraged the wrong way, by socializing risks and privatizing benefits. The government has accepted all the debt obligations of the private sector, and taxpayers now owe this money.
• The only way to reform corporate governance is to get the owners—the shareholders—of companies involved and actually paying attention.
• All of this is very tough: being able to diagnose a problem is a whole lot easier than mustering the will to fix it. "

Law faculty recruitment

The Association of American Law Schools (AALS) helps organize law faculty recruitment, with services including a database of candidates called the Faculty Appointments Register, a job advertisement service called the Placement Bulletin, and a dedicated Faculty Recruitment Conference (different from the annual meeting of the organization), which this year took place Nov 5-7.


Here's an account of the experience from a survivor: One Candidate's Experience in the AALS Hiring Process

"As you can imagine, my experience at the hiring conference mainly consisted of running up and down staircases, from one building to the next and back again. I scheduled 15 interviews on Friday and began my day with seven back-to-back. My eight years of competitive speech tournaments, which also consisted of running from room to room talking all day long, were good preparation. I think the best advice that I got about the hiring conference was from Dean Blake Morant, who advised the candidates at an opening session to “be our most authentic selves” and “bring up the energy level in the room” during each interview. "
...
"One of the most interesting and craze-inducing aspects of the hiring process was the law school hiring discussion on Prawfs Blawg. The four threads, which began on August 19th, have received well over 1300 comments. I admit that I read the threads nearly every day in the weeks before and after the hiring conference. I’m not sure that I know why, except that I felt that I was part of a large anonymous community of people who were just as freaked out and insecure as I was. I suppose its better to be in such a community of such people than be alone.
If I have learned anything from this process, it is that nobody really knows the secret to success and, in fact, the process is so individualized to particular hiring committees in a particular year at a particular school, that there likely is no secret. This is extremely frustrating to wanna-be law professors because we are analytical people. We (sometimes desperately) want to know the rules and the facts so that we can weigh our odds and predict our futures.
One big gaping hole getting in the way of our analysis is the lack of data on the members of the candidate pool. A few schools do a great job advising their alumni and keeping track of those in the process (shout out to Akiba Covitz!). Most don’t, and nobody aggregates that data. It appears that AALS doesn’t release it either (other than to the schools in the FAR forms themselves). So the candidates are left to guess who their competition is and how they stack up."

Kidney exchange news from Britain

David Manlove writes:

Dear Al,

I just wanted to pass on some KE news: the first 3-way kidney exchange in the UK has just been announced:

http://news.bbc.co.uk/1/hi/health/8552162.stm
http://news.bbc.co.uk/1/hi/health/8554930.stm
http://www.hta.gov.uk/newsandevents/htanews.cfm/837-First-pooled-transplants-performed-in-the-UK.html

Also I've been successful with a grant proposal to NHS Blood and Transplant and they will be funding us (i.e., me and former PhD student Gregg O'Malley; hopefully Peter Biro will be involved too) to work for a year on delivering a software package to enable them to carry out the quarterly matching runs for themselves, without having to send the data to us. The NHSBT collaboration builds on the work we've been doing together over the last 3 or so years (we've been involved in the quarterly matching runs since July 2008): http://www.organdonation.nhs.uk/ukt/about_transplants/organ_allocation/kidney_(renal)/living_donation/paired_donation_matching_scheme.jsp.

Our paper describing some aspects of this work appeared in the new journal Discrete Mathematics, Algorithms and Applications (vol. 1, no. 4, pp. 499-517, 2009, here. Also here are some slides from a talk I gave at a workshop in Bristol last year: http://www.cs.bris.ac.uk/Research/Algorithms/BAD09/Talks/BAD09-Manlove.pdf. I will be giving an updated version at a workshop on Matching Theory and Mechanism Design organised by Elena Inarra in Oxford next Tuesday.

Hopefully NHSBT will be bringing in domino paired chains triggered by altruistic donors in the near future - we are still trying to convince them of the merits of never ending altruistic chains!

Reading, writing and apologizing about repugnant transactions: Repugnance at multiple levels

A story in Al Jazeera concerns conflicting views of repugnant transactions--things that some people think other people shouldn't do--on multiple levels. The story concerns judicial flogging of women for adultery in Malaysia, a newspaper editorial against that practice by a non-Muslim editor, a government threat to close the newspaper for publishing the editorial, and a religious ruling that Muslims should not read the editorial.

The Al Jazeera story is here: Malaysia - Caning the messenger?

The Malaysian newspaper, The Star, has withdrawn the editorial from its website, but the Al Jazeera story concludes with this paragraph containing a link to a copy of the offending editorial:

"For people who want to make up their own mind about the issue, the text is still available here, but here's a clear warning, this article has already been deemed unacceptable by some Muslims. Those who agree with Mais - that non-Muslims should not comment on matters pertaining to shariah law - are strongly advised not to follow the link."

The multiple levels of repugnance remind me of another recent story in the news: Danish newspaper provokes uproar with apology over Muhammad cartoon
"A Danish newspaper was accused yesterday of betraying the freedom of the press after it apologised to Muslims for offence caused by its reprinting a cartoon showing the Prophet Muhammad with a bomb-shaped turban.
Politiken, a leading Danish newspaper, had printed the cartoon as a gesture of solidarity after three people were arrested for planning to kill the cartoonist, Kurt Westergaard. "

I guess I'll have to add reading and apologizing to my growing list of repugnant transactions, which already included adultery and publishing.

"Tissue rights"

Who has the rights to a cell line created from cancerous tissue? The NY Times reviews the book “The Immortal Life of Henrietta Lacks” (Crown Publishers), by the journalist Rebecca Skloot.

A Lasting Gift to Medicine That Wasn’t Really a Gift

"The notion of “tissue rights” has inspired a new category of activists. The question that comes up repeatedly is, if scientists or companies can commercialize a patient’s cells or tissues, doesn’t that patient, as provider of the raw material, deserve a say about it and maybe a share of any profits that result? Fewer people these days may be willing to take no for an answer. "

Embryo exchange in Georgia

It's not what it sounds like, and it doesn't have tax consequences:

Embryo Exchanges and Adoption Tax Credits by
Sarah B. Lawsky and Naomi Cahn

Abstract: The “Option of Adoption Act,” a Georgia law that was introduced by a staunchly anti-abortion Georgia state representative, establishes procedures for genetic donors to relinquish their rights to embryos before birth and permits, but does not require, embryo recipients to petition a court for recognition that they are the legal parents of a child born to them as a result of an embryo transfer. This article clears up what seems to be widespread confusion about a fairly straightforward question of tax law related to such embryo “adoptions.” Notwithstanding various sources' claims to the contrary, neither a Georgia adoption tax credit nor a federal adoption tax credit is available for “adopting” an embryo.

Matching for adoption

"In most cases, a successful domestic adoption is the result of a match between a birth mother (BMO hereafter) who seeks to relinquish her child, and prospective adoptive parents (PAPs hereafter). The underlying matching process involves a bilateral search characterized by several layers of mediation: Typically, adoption agencies represent BMOs, while PAPs work vis-à-vis adoption agencies, lawyers, or facilitators. In this paper, we exploit the unique nature of a new data set documenting the operations of an adoption facilitator. We analyze the preferences of PAPs over the attributes of babies relinquished for adoption, the BMOs’ choices, and the factors that determine ultimate outcomes (i.e., a successful adoption, a decision to parent by the BMO, or the child’s placement in foster care).

That is from the paper Gender and Racial Biases: Evidence from Child Adoption, by Mariagiovanna Baccara , Allan Collard-Wexler, Leonardo Felli , and Leeat Yariv.

The paper has a market design aspect:
"Despite the social value of a well-functioning matching process that delivers suitable parents to every child, adoption has not received much attention by the economics literature. Our analysis of parents’ preferences, combined with the identification of factors facilitating an ultimate match, opens the door to policy interventions aimed at increasing the efficiency of this process."

Same sex marriage in Mexico City: starting today

Gay Marriage Puts Mexico City at Center of Debate : "A new Mexico City law goes into effect March 4 that will allow same-sex couples to marry and adopt children, propelling the city to the forefront of the global gay rights movement."
The law seems to have survived the expected judicial challenge: Mexico's Supreme Court Upholds Gay Marriage Law , and here's a nice story about the (ongoing) debate in yesterday's Washington Post, With same-sex marriage law, Mexico City becomes battleground in culture wars

Here are my other posts on same sex marriage, which strikes me as an excellent example of how views and laws can change regarding repugnant transactions.
