College admissions in the UK, update
Act fast to snap up a place
Competition to make it to university through clearing will be more intense this year as applicants chase fewer places
Guide to Clearing: essential information on universities in the clearing system
John O’Leary outlines some of the pros and cons of 40 UK universities likely to be offering the most places through clearing this year
A-level system will not help students 'trade up'
Pupils who do better than expected in exams will miss out on places at leading universities because courses are already full.
"Those who are unfairly marked down in A-level exams could lose their place, even if they successfully appeal and later get a higher grade. Some courses are closed to British applicants even though they still have places for foreign students. This is because for financial reasons the Government restricts the number of British students that universities can recruit. Overseas students pay higher fees and do not receive the grants or subsidised loans available to home students. "
There's also a guide to the mysteries of college admissions on this side of the pond: How to get into an American university
Students are increasingly looking across the Atlantic for university – but the application system can seem daunting.
"One of the main differences between the US and here is that there is no central body that handles the admissions, as Ucas does in the UK. "
Here are my earlier posts on British college admissions:

Mazel tov to Methodist Hospital in San Antonio
"The transplant team at Methodist Specialty and Transplant Hospital performed their first exchange procedure in March 2008 and completed the 50th procedure just 19 months later, with 42 of the exchange transplants performed in just the past 10 months. "
Update: here's a link to the hospital's news release, which makes clear that they are performing all these exchanges primarily among patients in Texas: Methodist Specialty and Transplant Hospital Reaches National Milestone with 50th Paired Kidney Exchange Transplant
Competition among stock exchanges
"While the exchange has been under assault since the beginning of the decade, its decline has accelerated in recent years as aggressive competitors have emerged. Today, 36 percent of daily trades in stocks that are listed on the New York Stock Exchange are actually executed on the exchange, down from about 75 percent nearly four years ago. The rest of are conducted elsewhere, on new electronic exchanges or through dark pools. "
..."Unlike the Big Board, the new electronic exchanges are virtually unknown outside financial circles. Direct Edge, the largest, is in Jersey City. Another, the BATS Exchange, is based in Lenexa, Kan. Both are only about five years old. But each now accounts for about a 10th of daily United States stock trading. "
I'm reminded of Estelle Cantillon's paper with Pai-Ling Yin on a battle between London and Frankfurt exchanges: Competition between Exchange: Lessons from the Battle of the Bund

More on repugnant language
Oxford University Press has just issued a new edition of The F-Word. Their blurb begins:
"We all know what frak , popularized by television's cult hit Battlestar Galactica , really means. But what about feck ? Or ferkin ? Or foul --as in FUBAR , or "Fouled Up Beyond All Recognition"? In a thoroughly updated edition of The F-Word , Jesse Sheidlower offers a rich, revealing look at the f-bomb and its illimitable uses. Since the fifteenth century, no other word has been adapted, interpreted, euphemized, censored, and shouted with as much ardor or force..."

Peer effects in learning and teaching, but not in golf
The second paper does find peer effects in random groupings of cadets at West Point, and the third paper finds that students do better when their teachers have better colleagues, i.e. they find that the teachers experience peer effects as measured by the performance of their students.
*The three papers are:
"Peer effects in the workplace: Evidence from random groupings in professional golf tournaments," by Jonathan Guryan, Kory Kroft, and Matthew J. Notowidigdo.
"The Effects of Peer Group Heterogeneity on the Production of Human Capital at West Point," by David S. Lyle.
"Teaching Students and Teaching Each Other: The Importance of Peer Learning for Teachers," by C. Kirabo Jackson and Elias Bruegmann.

Paul Milgrom: Nemmer's Prize Lecture and Conference
His talk will be followed by a conference in his honor tomorrow.
Here's the abstract of Paul's talk:
"Market design has become an exciting area of economics research, with many of its findings useful for setting detailed rules in real markets. For matching markets, most proposed designs aim to be "straightforward" - making it a dominant strategy for participants to report information truthfully. But some recent matching and auction designs sacrifice incentive-compatibility conditions to give priority to various other desiderata. This lecture reviews the goals of market design and the unavoidable trade-offs that are sometimes required, and explores how economists should seek to resolve these trade-offs. "
Here's the conference lineup:
Vijay Krishna (Pennsylvania State University): Auctions and Information
Larry Ausubel (University of Maryland): Auctions with Multiple Objects
Panel Discussion: Market Design.Moderated by Rakesh Vohra (Northwestern University): Susan Athey (Harvard University), Preston McAfee (California Institute of Technology), Alvin Roth (Harvard University), Paul Milgrom (Stanford University)

Voters find same sex marriage repugnant in Maine
"Maine voters overturned the state’s same-sex marriage law yesterday, delivering a potentially crushing blow to gay-rights advocates after a year when their cause seemed to be gaining momentum with legislative and legal victories in four states."...
"The “people’s veto’’ came six months after Maine’s law was approved, and one year after California voters rejected gay marriage by a similar margin."
So same sex marriage has been moved out of the repugnant category in several states by courts, and by legislatures, but not yet by voters. As the AP report notes (ungrammatically),
"Gay marriage measures have lost in every state, 31 in all, in which it has been put to a popular vote. "

The DARPA network challenge
Noam Nisan has some thoughts on this at AGT, and points out that very quickly some people started to offer to share the prize among those who would notify them of individual balloon's locations, conditional on the team formed in this way winning. Here's a wiki for people to share market design ideas on how to form a winning team.
Note that this is an aggregation of information problem a little like a prediction market, even though it is for postdiction rather than prediction...

Blackmail, legal and illegal
Doing it on your own is illegal, but if you do much the same thing by threatening a lawsuit, it is legal.
"Blackmail is a “wonderfully curious offense,” to use the phrase of Paul H. Robinson, a professor at the University of Pennsylvania Law School and his coauthors in a recent paper. A threat to tell the truth is no crime, and neither is asking someone for money. But if you demand money to prevent the truth from being told, Professor Robinson said, you’ve crossed the line. At its core, he explained, the offense is “a form of wrongful coercion.” "
However you can threaten to sue if a settlement is not reached first, and that isn't blackmail.
"Those confrontations, however, did not cross the line into the criminal realm, he said, because they had been sanitized by lawyering. Attorneys, he noted, can create a legal filing that promises to bring out unpleasant facts in depositions or during trial; a settlement is not, technically, a payoff. He called it “wrapping an extortion threat in a legal cloak.”
It happens all the time, said Gerald B. Lefcourt, a criminal defense attorney in Manhattan. “Threatened lawsuits, and even filed lawsuits, are often no more than blackmail,” he said.

Compensating donors: how about bone marrow?
"Prohibiting someone from making money for donating an irreplaceable kidney is one thing. But what about donating bone marrow, which replenishes itself within weeks?
That question is at the heart of a new lawsuit, filed Monday, challenging the constitutionality of the federal law that prohibits compensating bone marrow donors. The plaintiffs want to make modest recompense for such donors legal — say, paying partial tuition for a college student or making a mortgage payment for a first-time home buyer.
In the lawsuit filed Oct. 26 in the U.S. District Court for the Central District of California, cancer and blood disease patients and health care advocates are suing U.S. Attorney General Eric Holder Jr. to enjoin enforcement of provisions of the National Organ Transplant Act of 1984 that criminalize compensating donors. They argue the statute violates due process rights and interferes with public health.
"This constitutional challenge is about an arbitrary law that criminalizes a promising effort to save lives," the complaint states. A bone marrow transplant is often the "only hope" for tens of thousands of Americans diagnosed with a deadly blood disease such as leukemia. "There is a desperate shortage of unrelated marrow donors, particularly for minorities," the complaint says.
Offering modest incentives to attract more donors could end that shortage, argued Jeff Rowes of the Arlington, Va.-based Institute for Justice, who is the lead attorney for the plaintiffs. "
Megan McArdle links to the Institute of Justice press release, and suggests that inclusion of bone marrow in the National Organ Transplant Act was simply a mistake.
A paper on bone marrow donation recently appeared in the American Economic Review, you can find an ungated version here: One Chance in a Million: Altruism and the Bone Marrow Registry
by Ted C. Bergstrom, Rod Garratt, and Damien Sheehan-Connor.
The paper argues that (because of the need for bone marrow matches to be perfect on the 6-vector of Human Leukocyte Antigens, and because of different distributions of these by race and ethnicity), we would get more bang for the buck by investing in recruiting more minority donors than additional random donors.
As it happens, for non-minority donors, the present policy in many places is just the opposite of compensating donors; if you want to register as a bone marrow donor you may have to pay the costs, presently around $65.

Market design in science fiction
"I hope you're doing well. I've been greatly enjoying your mechanism design blog.
I'm not sure if you like science fiction, but if so, I thought you'd be amused to know that a recent scifi novel includes a plot point based around mechanism design. The novel is Eye of the Storm by John Ringo.
The basic gist is that, in previous books, the US had to create a humongous army to fight off an alien invasion. It then dropped down to only nominal force levels for a few decades (during which the ex-soldiers didn't age because of "rejuv" technology). Now they need to quickly create a new army, so to start with they've called up enough soldiers for a couple of divisions. The mechanism design part is that they decide to staff the divisions by letting officers use points to bid on their positions and subordinates. Some of the more talented officers decide to collude to game the system.
I've gone ahead and copied in the relevant chapters, in case you find it amusing. "
If I could have figured out how to create an "after the jump" break on this blogger I would have included the long, interesting excerpts Stephen included, which, among other things, had sniping in a combinatorial auction as a critical strategy.

The "Netflix for academic journals"
"By opening the largest online rental service for scientific, technical, and research journals, the company Deep Dyve is hoping to do for academic publications what Netflix has done for movies: make them easily accessible and inexpensive for everyone.
The Web site has been an academic-journal search engine since 2005 and unveiled its rental program this week. Now anyone can “rent” an article—which means you can view it on your computer without ownership rights or printing capabilities—for as little as 99 cents for 24 hours. Users can also subscribe for monthly passes. Currently the site has 30 million articles from various peer-reviewed journals.
William Park, chief executive of Deep Dyve, says the model will not only allow more people to read articles they might otherwise not see, but will actually encourage users to purchase more content from journals. He says that now, only about 0.2 percent of people visiting journal Web sites go on to buy articles, because they don’t know exactly what they are getting from just a title and an abstract.
“Nobody would buy a car without at least evaluating it first,” Mr. Park says. “The same is true for anything, whether it’s a dollar or $10,000.”
Mr. Park says that Deep Dyve has revenue-sharing partnerships with hundreds of publications (about 80 percent of which are scientific) and hopes to expand to more of the humanities within the coming months."
Forced Labor
The terms "debt bondage" and "bonded labor" appear to be terms of art for involuntary servitude in various forms.
The book is mostly about the developing world, although there is a chapter on "Trafficking for Forced Labor in Europe," concerning migrant workers. The book has no chapter on the United States (where newspaper reports about involuntary servitude mostly seem to focus on illegal immigrants caught up in forms of indentured servitude, and sometimes deal with prostitution). I would be glad if that is because the 13th Amendment to the U.S. constitution is largely effective:
"Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."

Hours per week worked by (young) surgeons
The report argues that frequent handoffs allow patient information to be lost, as doctors have less chance to observe changes in a patient's condition.
"Surgeons across the country say patients are much less safe in the NHS since the August introduction of European Working Time Regulation (EWTR) 48 hour working limits as continuity of care for patient collapses, this is the damning assessment of a survey of NHS surgeons. Services are only being held together by a ‘grey market’ of doctors willing to covertly breaking the legislation to maintain care for patients."
..."The College surveyed 900 surgeons - almost an eighth of the UK surgical workforce – with responses from more than 360 consultants and more than 500 trainees to see how surgical services were faring under the new working time restrictions. It found some alarming results:
...
"A third say handover arrangements are inadequate in their hospital and 23 per cent say they cannot stay involved in all stages of individual patients clinical care that require their expertise."
...
"Patients are being lost and at increased risk of dying as a direct result of so many shift changeovers and rotas which leave no time available to handover. Trainee surgeons across the country are staying on unpaid after the hours limit because they want to see through care for patients. They are also taking on additional paid locum work in the hope of gaining the training opportunities they cannot get in their formal working week. Meanwhile hospitals are relying on this goodwill because they know they couldn’t stay open without them. As a result there is an emerging grey market in hospital cover with doctors true working hours being kept off the books."
On the other side is the argument that sleepy doctors endanger patients. We don't let airline pilots work long hours, why should the doctors who staff emergency rooms and operating rooms be different?

College admissions in Illinois, conclusion?
Richard Herman, chancellor of the University of Illinois at Urbana-Champaign, has resigned in the wake of an admissions scandal in which well-connected applicants were put on a "clout list" and given preferential treatment, the Chicago Tribune reported on Tuesday. Mr. Herman, who made a remorseful apology to the faculty after a state panel found he was the "ultimate decision maker" for clout-listed applicants, will join the university's faculty. His resignation follows those of the university president last month and several trustees.
