American Math Monthly reprints Gale and Shapley 1962

The journal is available on jstor and to members, but here is some of the front material. The paper itself is well worth reading, and I've posted a link to an un-gated version below.


THE AMERICAN MATHEMATICAL MONTHLY VOLUME 120, NO. 5 MAY 2013
A Letter from the Editor 383
Scott Chapman

"...This month, we honor the Nobel Prize-winning accomplishments of Lloyd Shapley. Shapley’s 1962 MONTHLY paper “College Admissions and the Stability of Marriage,” co-authored with David Gale, is well-known to long-time MONTHLY readers. According to Google Scholar, the Gale/Shapley paper has been referenced over 2500 times (among MONTHLY articles, only Li and Yorke’s 1975 paper “Period three implies chaos” has been referenced more). Hence, when the announcement was made late last year that Shapley and Alvin E. Roth had been awarded the Nobel Prize in Economics “for the theory of stable allocations and the practice of market design,” it
was not a surprise that the 1962 MONTHLY paper was cited by The Royal Swedish Academy of Sciences. I did find it surprising that many of the younger members of the MONTHLY Editorial Board were completely unaware of this paper. Vadim Ponomarenko wrote me the following: “The article is not only short and ground breaking, but really well-written and interesting. I think the MONTHLY should republish this article in its entirety.” Thus was born the idea to honor Shapley by reprinting his article.
I thank Ehud Kalai, a long-time colleague of Shapley’s and the James J. O’Connor Professor of Decision and Game Sciences at the Kellogg School of Management at Northwestern University, for offering to write a Foreword to Gale and Shapley’s work.
I believe that his Foreword speaks for itself, but add that the MONTHLY Editorial Board sees the reprinting of Gale and Shapley’s paper as a special opportunity to open this classic piece to a new generation of mathematicians."



Foreword: The High Priest of Game Theory 384
Ehud Kalai

"In “Von Neumann, Morgenstern, and the Creation of Game Theory” [1] Robert Leonard describes a 1948 public lecture presented by John von Neumann at the RAND Corporation in Santa Monica. The lecture was interrupted by a young voice from the back protesting “No! No!, that can be done much more simply!” According to Hans Speier, a director at RAND, you could have heard a pin drop as von Neumann said “come up here, young man. Show me.” The young man goes up, takes the piece of chalk, and writes down another derivation as von Neumann interrupts and says
“not so fast, young man. I can’t follow.” The young protestor was Lloyd Shapley, and following this incident he was awarded a stipend to study game theory at Princeton, a fortunate occurrence for the future of game theory.
More than a half a century later, the 2012 Nobel Prize in economics was awarded to Lloyd Shapley and Alvin Roth. Roth opened his Nobel Prize lecture with the following sentence: “Lloyd, when I began studying game theory your work touched every part of it and shaped it, and you were an inspiration not just for me but for the whole generation of game theorists that followed you. . . .” Robert Aumann, the 2005 Nobel Laureate game theorist who often introduced Shapley as the “High Priest of Game Theory,” stated in his Nobel Prize Lecture that Lloyd Shapley is the “greatest game theorist of all times.”...

The culture of universities (and the importance of hyphens)

I've blogged before about universities and how university culture interacts with the larger culture.
I am reminded of this by a recent Times Higher Education article that I saw in Inside Higher Education, about changes being made in some of the new universities that are trying to get going in Dubai: Adjustments in Dubai

The following paragraph illustrates the clash of cultures, and also the importance of properly placing hyphens (think about what it would mean, for the paragraph and for Dubai, if each hyphen were moved a word earlier...)

"The buzz of activity at Heriot-Watt's campus is surely exactly what was planned when the Dubai Knowledge Village, the first "knowledge free-zone" opened in Dubai in 2003. Like the country's "media free-zone" and "business free-zone," it was set up to allow organizations to operate without the constrictions of Islamic-based Emirati laws."

 The article goes on to say that a large proportion of the students at the British universities in Dubai are Indian students who are unable to go to British universities for one reason or another. One reason for this, apparently, is that within Dubai there is some difficulty in emigrating from the free-zone back to the -free zone:

"International employers in Dubai may be happy to accept courses offered via the free zone's own independent accreditation system, which is overseen by international quality review, but the powerful Emirati government is believed to favor courses that follow its own accreditation model. It is clearly a factor in deciding which institution to attend, according to one student.
"I want to study at one of the UK or U.S. universities at DIAC, but it's very hard to get a civil servant job with these qualifications," she observes. "

How restaurants deal with no-shows

Here's an article from eater.com with interesting details on the different marketplace institutions being tried to limit no-shows at high end restaurants...from abolishing reservations, to overbooking, to credit card reservations with penalties, to a theater-ticket model.  How Restaurants Can Deal With No-Show Diners

HT: Neil Dorosin (who points out that somewhat similar issues arise in school choice, since schools also suffer from no-shows when the school year begins)

Experimental social science conference at Stanford

West Coast Experiments Conference, May 10, register by May 1....http://ps-experiments.ucr.edu/conference/western


WCE.2013, Stanford University: The sixth annual meeting of the West Coast Experiments Conference will be held at Stanford University on Friday, May 10.
We encourage anyone with an interest in experiments to attend; graduate students are especially welcome, as well as those who are new to experimental research. The WCE conference is organized more as a methods "workshop" than as a venue to engage in subfield debates. Presenters focus on one or two methodological take away points of their experimental work. The goal is to give the audience applied, practical advice on methods and design in a way that will help them improve their own experimental research.
The WCE conference is a single day meeting, starting at 9 and ending after dinner. Although we do not have the money to cover travel or lodging expenses, we will provide all meals on that day and we promise a good conversation.

The conference will be held in the Koret Taube Conference Center at the Stanford Institute for Economic Policy Research (SIEPR), located at 366 Galvez Street.
Presentations include (in no particular order):
Social experiments that really matter in the real world:
Advances in statistical methods for counterfactual inference:
  • Guido Imbens (Stanford Graduate School of Business): Some comments on stratification and re-randomization in randomized experiments
  • Luke Keele (Penn State Political Science): Conditioning on posttreatment quantities with structural mean models
Experimental design in political psychology applications:
  • Jennifer Merolla (CGU Political Science): Methodological issues surrounding the use of theDynamic Process Tracing Environment (DPTE)
  • Eric Dickson (NYU Political Science): "Legitimacy and Enforcement: An Experimental Investigation" (using experimental games to measure psychological quantities and parse psychological mechanisms, joint work with Sandy Gordon and Greg Huber)
  • Gabriel Lenz (Berkeley Political Science): Identifying the effect of candidate appearance on vote choice (without assigning candidates to plastic surgery....)
Ted Miguel (Berkeley Economics) also will give an update on the Berkeley Initiative on Transparency in the Social Sciences (BITSS) at lunchtime.

Funding
The conference is made possible by generous funding from the Institute for Research in the Social Sciences at Stanford, the Stanford Institute for Economic Policy Research, and the Stanford Department of Political Science.

Carbon emissions permits are cheap in Europe

The NY Times has the story: In Europe, Paid Permits for Pollution Are Fizzling

"More important, though, than lost jobs and diminished payouts for traders and bankers, the penny ante price of carbon credits means the market is not doing its job: pushing polluters to reduce carbon emissions, which most climate scientists believe contribute to global warming.

"The market for these credits, officially called European Union Allowances, or E.U.A.’s, has been both unstable and under sharp downward pressure this year because of a huge oversupply and a stream of bad political and economic news. On April 16, for instance, after the European Parliament voted down the proposed reduction in the number of credits, prices dropped about 50 percent, to 2.63 euros from nearly 5, in 10 minutes.

“No one was going to buy” on the way down, said Fred Payne, a trader with CF Partners.

"Europe’s troubled experience with carbon trading has also discouraged efforts to establish large-scale carbon trading systems in other countries, including the United States, although California and a group of Northeastern states have set up smaller regional markets.

"Traders do not mind big price swings in any market — in fact, they can make a lot of money if they play them right.

"But over time, the declining prices for the credits have sapped the European market of value, legitimacy and liquidity — the ease with which the allowances can be traded — making it less attractive for financial professionals."

The NY Times debates whether prisoners should be able to donate organs


Organ Donors Behind Bars

DEBATERS

INTRODUCTION

Nicole Bengiveno/The New York TimesWould the recipient of this organ care whether it came from a prisoner?
Utah recently became the first state to explicitly permit general prisoners – not death-row inmates – to donate their organs if they die while incarcerated. Should more states have laws like this? Should prisoners be allowed to make live donations to people other than family members? And with nearly 118,000 people in the U.S. waiting for hearts, kidneys, livers and other life-saving transplants, why not include death-row inmates?

Tickets For Apple’s WWDC 2013 Sell Out In Under 2 Minutes, Compared To 2 Hours In 2012


Tickets for Apple’s annual Worldwide Developer’s Conference went on sale today at 10 AM Pacific, 1 PM Eastern, and as expected, sold out in record time, at just under 2 minutes. Tickets for the developer-focused event at San Francisco’s Moscone West, which features presentations and one-on-one time with Apple’s own in-house engineers, sold out in just two hours in 2012, in under 12 hours in 2011, and in eight days in 2010.
...
This year also marks the first time Apple has provided advance notice regarding when tickets would go on sale, which almost definitely contributed to the faster-than usual sell-out this time around. Imagine a crop of millions of developers around the world hovering over their computers, waiting for the buying process to go live.
The quick sell-out is made more impressive by the fact that sales of the $1,599 tickets were limited to just one per person, and five per organization, tracked by individual Apple ID. During a previous keynote, former CEO Steve Jobs said that there were over 5,000 attendees at the show, which means that Apple potentially just made as much as $8 million in roughly 90 seconds in gross revenue from the event.
Apple’s developer economy is now a massive industry, having paid out $9 billion in total to developers, at a rate now of around $1 billion per quarter. Both iPhone and iPad audiences continue to grow, and Apple’s tablet especially showed tremendous progress during Apple’s most recent fiscal quarter. While Mac sales seem to be either flat or on the decline, the global growth of the iOS user pool more than makes up for that, and iOS as a platform is still the primary revenue driver when it comes to mobile apps and advertising. Combined, those factors mean interest in tickets for WWDC isn’t likely to flag anytime soon.

Skepticism about presumed consent in organ donor registration

Donate Life California posts a skeptical account of proposals to switch from opt in to opt out: An Attractive Concept with Unattractive Results

"72% of Californians and 75% of Americans who can become organ donors actually donate and save lives at the time of their deaths. Second,  California’s actual donation rate of 32.3 nDPM (normalized Donors per Million population[iv])  leads the US ‘s 26.1 nDPM and every country in the world except for Spain’s 33.5 nDPM[1] Meanwhile all other countries trail donation in California and the US; whether they have Presumed Consent or Explicit Consent laws."
...

"Most significant in this assessment of PC vs EC is the fact that the European countries that developed and maintain presumed Consent in their laws do not rely on it to actually recover organs.  A 2012 survey of practices reports[vi] that donation professionals in all of these countries require family consent prior to recovery of organs. The fact that all countries that have PC laws do not actually rely on the right of the state to take organs speaks to the public trust and autonomy issues that arise when countries seek to claim any type of property, and makes it clear that the variance in donation rates is a function of cultural and operational aspects rather than legal characteristics of their donation programs."

Gay marriage in France

Here's the story from the Guardian about what appears to be the end to a contentious transition in France from an illegal, repugnant transaction (actually, not just marriage, but also adoption, so two repugnant transactions) to transactions fully sanctioned by law, although still with substantial numbers of opponents:

France approves same-sex marriage: Passing of law allowing gay couples to marry and adopt children comes after heated debate in parliament and weeks of protest

France has become the 14th country to legalise same-sex marriage , pushing through François Hollande's flagship social change after months of street protests, political slanging matches and a rise in homophobic attacks.
After 331 votes for and 225 votes against, there were chants of "Equality. Equality." in the French assembly, where the Socialists have an absolute majority. But thousands of riot police and water cannons were in place near the parliament building in Paris in advance of planned demonstrations against the law.
The right to marriage and adoption for everyone regardless of sexual orientation has proved bitterly divisive in France, triggering the biggest conservative and rightwing street protests in 30 years. Recent weeks have seen more than 200 arrests as police teargassed late-night demonstrators near parliament. More than 172 hours of heated debate in the assembly and the senate meant the bill was one of the most debated in recent history, with furious clashes and a near fist-fightbetween politicians.
One rightwing MP warned the government was "killing children" by allowing same-sex married couples to adopt and one senator warned gay marriage would open the way to people being able to marry animals or objects. MPs in favour of the bill received death threats, skinheads attacked a gay bar in Lille, and gay rights groups reported a rise in homophobic attacks.
Before the vote, the speaker of the assembly ordered the expulsion of noisy protesters from the public gallery, calling them "enemies of democracy".
The vote makes France the ninth country in Europe to legalise same-sex marriage and the first ceremonies could take place this summer.

Recommender algorithms for labor market search

Aki Ito has written a nice story at Bloomberg News about ongoing efforts to design labor market search engines to deal with congestion: Algorithms Play Matchmaker to Fight 7.7% U.S. Unemployment: Jobs

She writes about sites like AfterCollege and CareerBuilder and Burning Glass, as well as the online IT marketplace ODesk.

There's a lot going on in labor market matching and matchmaking, and lots of good market design  problems in that space.

Is freedom to do social science research like freedom of the press?

 A group of British social scientists (who appear to mostly be involved in survey research) think that the current system of institutional review of research in Britain is better suited to medical experiments than to social science.

Here's the story:


Social Science Ethics
March 14, 2013 - 3:00am
British social scientists are drawing up a common set of ethical principles aimed at freeing research from what they see as excessive ethics oversight frameworks that hamper their ability to improve social understanding.
According to Robert Dingwall, professor of social science at Nottingham Trent University, a "free" social science research base is as important to a healthy democracy as a free press. But in the past decade, British and international funders have required universities to vet all research involving human subjects via institutional ethics committees.
"You can imagine how outraged journalists would feel if they had to pre-check with a committee that their questions would not upset someone," he said.
Dingwall, a member of an Academy of Social Sciences working group on the issue, said committee members often had no expertise in ethics or the research field in question, and were primarily concerned with the university's reputation. Their risk aversion fed back to academics, who were often disinclined to undertake research that could incur disapproval even if it was potentially important.
The situation was exacerbated, Dingwall said, by the application to social science of frameworks developed for biomedicine. He said the balance of individual risk and social benefit was different in the social sciences because most research posed a minimal risk to individuals and offered significant benefit to the community.
He said that although the U.S. and Canada have recognized that the regulatory system was in crisis, Britain has yet to join efforts to redress it.

Paul Milgrom's Wikipedia page (and 65th birthday present)

Today is Paul Milgrom's 65th birthday, and is the second day of a conference in his honor that has brought his students and other admirers from all over the world. Joshua Gans led the creation of the birthday present, which involved bringing  Paul Milgrom's Wikipedia page up to snuff. As Joshua announced at the dinner last night, it is presently the longest Wikipedia page for any living economist (maybe for any economist, I didn't get that clear...). Here's a picture of it being presented to Paul in scroll form, held up by those of his students who were present:

Someone was pretending to be me on Google+ (a story with a happy ending)

The internet is home to a variety of scams, and some of them involve trying to manipulate Google search results. So I was surprised and dismayed, but not entirely shocked, when I noticed that someone was pretending to be me, by establishing a Google+ page for a company called Market Design, whose web page was....this blog.

What could be in it for them?  Well, maybe they were really trying to pretend that by hiring them you were hiring me. But maybe they just were moving up in Google searches through the links that this blog gets.  Here's what you saw if you searched for "market design" on Google:


The first result, on the left, is my blog. But there's an item under it called "Google+ page" and an address, which both link to the spoofer, who is also on the right, with a phone number and a map, and a picture that if you click on it gets you to one of my blog posts.

If you clicked on the link that says Google+ page under the link to my blog, you got to this page, on which my blog URL was clearly displayed as the company web page:



On 4/7/13 I filled out a problem report on the Google+ profile page, and I wrote a review disclaiming any connection between their site and me or my blog...

Apparently Google pays attention to this kind of complaint. When I checked back on 4/9/13 the spoofer was already nowhere to be found.

A recent email confirmed this:

Bangladesh protesters demand blasphemy law with death penalty for bloggers

One repugnant transaction  isn't repugnant enough for protesters in Bangladesh:

Bangladesh protesters demand blasphemy law
"Hundreds of thousands of marchers call for law that would include death penalty for bloggers who they say insult Islam."

"The religious group, which has the backing of country's largest party Jamaat-e-Islami, organised the rally in support of its 13-point demand including enactment of a blasphemy law to prosecute and hang what they call atheist bloggers.
...
"Under the country's cyber laws, a blogger or Internet writer can face up to ten years in jail for defaming a religion."

Interview with the late Dr Joseph Murray, about the first kidney transplants and related matters

Great interview, conducted in 2000. Lots of detail. For example, he practiced on dogs, removing a dog's kidney and then transplanting it into the same dog, to practice the surgical techniques for kidney transplants without immunological complications...and discussion of repugnance... and of the generosity and courage of early transplant patients ...and the relationship between basic and applied science (18 minutes for the whole thing).

Here's the video from the Nobel site (I can't figure out how to upload it): http://www.nobelprize.org/mediaplayer/index.php?id=732 .

Here are my earlier posts on Dr. Murray who shared the 1990 Nobel Prize in Physiology or Medicine for "...discoveries concerning organ and cell transplantation in the treatment of human disease"

As it happens, a new model of unraveling of markets just came by email:
 STRATEGIC UNCERTAINTY AND UNRAVELING IN MATCHING
MARKETS, by FEDERICO ECHENIQUE AND JUAN SEBASTIAN PEREYRA

From their introduction:
"Strategic unraveling in our model proceeds as follows. There is a loss in efficiency when some agents go early: Information about the quality of the matches arrives late, so it is better for efficiency to wait until the information has arrived to make a match. If some agents go early anyway, this forces later matches to be less efficient. The result is a negative externality that makes it more tempting for all agents to go early. It may push some additional agents over the threshold by which they decide to go early. In turn, these additional agents going early makes it even more tempting to go early|and so on and so forth."
