Congestion and competition in college admissions (in the WSJ)

Is college admissions ripe for re-design?  (The problems outlined are real, but I'm skeptical that there's the consensus needed for a major overhaul...)

How to Fix College Admissions
Getting into a top school is a stressful, unpredictable process. Here are 10 ways to make it fairer and more transparent.  By Melissa Korn

"We asked college admissions officers, high school and private counselors, parents, students and others for ways to make the system fairer, more transparent and less painful for everyone involved. Here are 10 of their ideas—some easy to implement, others just meant to start a conversation—to reform the status quo.
...
"2. Limit the number of colleges to which students may apply. Thanks in part to the ease of applying online—especially through the Common Application, which allows applicants to use one basic form for hundreds of colleges—36% of students submitted seven or more applications in 2017, up from 10% in 1995. “The number of clicks you can make on the Common App causes congestion in the system,” says Alvin Roth, a Nobel Prize-winning Stanford University economist who helped to design the system that matches new doctors with residency programs.

"Schools pursue aggressive outreach, urging even fairly unqualified applicants to apply, then boast every spring about how many they rejected, as if exclusivity is proof of quality. Ballooning application numbers, combined with stagnant class sizes, cause acceptance rates to slide even lower into the single digits at places like Columbia and Pomona. As a result, high-school seniors apply to more schools just in case, and the vicious cycle continues—creating havoc for schools that can’t predict their yields. The overall yield rate for new freshmen at U.S. colleges fell to 34% in 2017 from 48% in 2007.
...
"Almost nobody needs to submit 20 applications; a reasonable limit would be as low as a half dozen, assuming that students receive meaningful counseling. High schools could enforce the cap by only agreeing to submit a certain number of official transcripts to colleges. The College Board and ACT could also limit distribution of SAT and ACT results, but they have little incentive to do so, since they make money from sending scores.
...
"9. ...Even more radical, schools could try some version of the algorithm used to determine matches for medical residency programs, which involves programs and medical students ranking one another and then being paired up by a computer system. This would be a heavy lift, however, as colleges would need to coordinate their procedures to rank candidates, run the computer program and inform all parties about the outcomes."

Seema Jayachandran on the Banerjee, Duflo, Kremer Nobel, in the NYT

The Economic View column of the NY Times, by someone who knows the subject, and the subjects very well:

When a Disappointment Helped Lead to a Nobel Prize
The winners of this year’s Nobel in economics did pioneering field experiments that sometimes didn’t work as expected.  By Seema Jayachandran

"The negative finding about textbooks was important in the development of Mr. Kremer’s career. “I’m happier when I find that something works,” he said. “But I’m not in despair if I don’t — the key thing is listen and learn from it.”

Who is a refugee? Remembering U.N. High Commissioner for Refugees Sadako Ogata

The Lancet recalls the life and work of Sadako Ogata, born 16 September 1927; died 22 October 2019.

Sadako Ogata
"Sadako Ogata began to transform UNHCR, the UN Refugee Agency, almost as soon as she became UN High Commissioner for Refugees in 1991. At the time, the Gulf War had displaced more than a million Iraqi Kurds and thousands were blocked from crossing into Turkey. They were in desperate need just inside the Iraqi border. Ogata quickly sought to expand UNHCR's rules to allow it to provide aid not only to refugees but also to people displaced within their own country. “Most of the senior leaders in UNHCR were against providing assistance to those Kurdish refugees because they were inside Iraq”, said Izumi Nakamitsu, who was based in Turkey at the time for UNHCR and accompanied Ogata on her first mission as High Commissioner to visit the displaced Kurds. “The refugee law says that you're not a refugee until you cross the border and senior officials advised her against providing protection and assistance. But she instinctively felt this was wrong”, said Nakamitsu, who is now a UN Under-Secretary-General and High Representative for Disarmament Affairs. Ogata's insistence that UNHCR provide aid to people who are internally displaced is one of her lasting legacies."

Divorce as a repugnant transaction

A recent obituary reminds me that divorce used to be a repugnant transaction, to which there were barriers even when both partners in a marriage were eager to end it on agreed upon terms.  It was a repugnant transaction because of the way we regard marriage as a protected transaction.

Jerome Wilson, Key in Revamping New York Divorce Law, Dies at 88
As a legislator in 1966, he led a commission that pushed to broaden the legal grounds for divorce. New York had been the last state to recognize only adultery.

"Jerome L. Wilson, a former Democratic state senator from Manhattan who helped liberalize a rigorous 18th-century law that had left New York as the sole state that required a spouse to prove adultery as the only legal ground for divorce, died on Friday
...
"The amended act, which took effect on Sept. 1, 1967, added four other grounds for divorce: cruel treatment, abandonment for two years, the sentencing of a spouse to prison for five years or more and a couple’s living voluntarily apart for at least two years.
...
"In the second year after the law went into effect, the number of divorces granted in New York ballooned to 18,000 in all five categories, compared with 4,000 granted only for adultery during the last year that the old law was in effect.

"Supporters of the changes said the new law also reduced instances of perjury (because so many estranged spouses had to lie about allegations of adultery) and end runs by wealthier couples who could afford to fly to Mexico or Nevada and remain there for two weeks to qualify for a divorce.
...
"Mr. Wilson’s first marriage, in 1957 to Frances Roberts, ended in divorce."

Paying participants in economic experiments, in Ireland, in jeopardy

On Wednesday I received some email correspondence about a difficulty being faced by experimental economists in Ireland, who may be forbidden from paying participants in experiments, at least if the money comes from research grants

The issue has to do with this sentence on page 6 of the research grant guidelines of the Irish Research Council.
"Participants in surveys/focus groups/workshops or other such project related activities may not
be paid..." although their travel expenses can be reimbursed.

I dashed off the following statement in support of efforts to make sure that this policy isn't interpreted as preventing standard economics experiments.

“Laboratory experiments in Economics largely depend on specifying precisely and attempting to measure or  control  the incentives of the participants in an experiment. Almost always this involves paying the participants in ways that conform to the incentives the experimenter is trying to create.  [Paying subjects] is a well established and almost universal practice in experimental economics, and often necessary for publication in internationally recognized economics journals.”

Regulations gone awry -- an example from transplantation

A general lesson of market design is that participants have big strategy sets, so any given set of rules can have unanticipated undesirable consequences.  Here's an example from transplantation. Transplant centers are regulated in part based on their one-year survival rate.

Here's a story from the BMJ:

US hospital is accused of keeping vegetative patient alive to boost its transplant survival rate

"Federal agents are investigating a New Jersey hospital accused of keeping a patient with catastrophic brain damage alive for a year and barely consulting his family, in order to keep its one year transplantation survival rate from falling to a level where the programme’s Medicare certification might be withdrawn.

"The Centers for Medicare and Medicaid Services, which has its own law enforcement agency, will lead the investigation into Newark Beth Israel Medical Center. The hospital has launched its own internal probe.
...
"Newark Beth Israel’s heart transplantation programme is among the top 20 in the country by volume. A banner on the hospital’s facade says, “1000 hearts transplanted. Countless lives touched.”

"But in 2018, its one year survival rate fell significantly below the 91% national average. Young’s death would bring the average down to 81%, which staff feared would trigger sanctions from the public payer."

Academic (computer science) conferences as marketplaces

Eppstein and Vazirani propose a centralized marketplace for computer science conferences:

A Market for TCS Papers??
November 19, 2019 by Kevin Leyton-Brown

By David Eppstein & Vijay Vazirani

"No, not to make theoreticians rich! Besides, who will buy your papers anyway? (Quite the opposite, you will be lucky if you can convince someone to take them for free, just for sake of publicity!) What we are proposing is a market in which no money changes hands – a matching market – for matching papers to conferences.

"At present we are faced with massive inefficiencies in the conference process – numerous researchers are trapped in unending cycles of submit … get reject … incorporate comments … resubmit — often to the next deadline which has been conveniently arranged a couple of days down the road so the unwitting participants are conditioned into mindlessly keep coming back for more, much like Pavlov’s dog.

"We are proposing a matching market approach to finally obliterate this madness. We believe such a market is feasible using the following ideas. No doubt our scheme will have some drawbacks; however, as should be obvious, the advantages far outweigh them.

"First, for co-located symposia within a larger umbrella conference, such as the
conferences within ALGO or FCRC, the following process should be a no-brainer:

1). Ensure a common deadline for all symposia; denote the latter by S.

2). Let R denote the set of researchers who wish to submit one paper to a symposium in this umbrella conference – assume that researchers submitting more than one paper will have multiple names, one for each submission. Each researcher will provide a strict preference order over the subset of symposia to which they wish to submit their paper. Let G denote the bipartite graph with vertex sets (R, S) and an edge (r, s) only if researcher r chose symposium s.

3). The umbrella conference will have a large common PC with experts representing all of its symposia. The process of assigning papers to PC members will of course use G in a critical way.

"Once papers are reviewed by PC members and external reviewers, each symposium will rank its submissions using its own criteria of acceptance. We believe the overhead of ranking each paper multiple times is minimal since that is just an issue of deciding how “on-topic” a paper is – an easy task once the reviews of the paper are available.

4). Finally, using all these preference lists, a researcher-proposing stable matching is computed using the Gale-Shapley algorithm. As is well-known, this mechanism will be dominant strategy incentive compatible for researchers." 

"With a little extra effort, a similar scheme can also be used for a group of conferences at diverse locations but similar times, such as some of the annual summer theory conferences, STOC, ICALP, ESA, STAC, WADS/SWAT, etc.

Matching officers to branches at West Point


West Point grads get assignments through new branching system
By Brandon OConnor

"During a ceremony Nov. 13, 1,089 members of the Class of 2020 at the U.S. Military Academy received their assignments for which branch of the Army they will start their careers in upon graduation.
...
"This year marked the first time West Point has assigned branches using the Army's new Market Model Branching System, which will be rolled out to ROTC next year. The new model paired cadets with a branch by considering how they ranked the 17 branches as it has in years past, but for the first time the commandants of each branch also had a vote in which cadets received their branch.

Following branch week in September, the cadets in the Class of 2020 locked in their branch preferences for the sixth and final time. They each ranked the branches one through 17, or one through 15 for female cadets who opted out of armor and infantry. Each cadet was also ranked as most preferred, preferred or least preferred by each branch based on their branch resumes and interviews, which cadets were given the option to take part in for the first time this year.

Before locking in their preferences, cadets were given information about how each branch ranked them as well as the results from a simulation using their fifth branch preference list which showed them where they would have been placed. The cadets then had the chance to use that information to adjust their preferences before locking them in for the final time.

Sunsdahl said they saw movement within the cadets' top four preferences following the simulation as cadets moved up the branches they had a better chance of receiving based on the commandant's feedback and moved down branches where their chances were lower.

"That was the market working, which helped branches get who they wanted as well," Sunsdahl said. "We talk cadet preference a lot, but branches got more of the people they wanted this year than they have in past years. That's where that commandant vote meant something. Now when somebody goes into a branch, the cadet wants to be there, and the branch wants them. It's a win-win."

Following the application of the matching algorithm, which was adapted from the medical residency matching program, and final adjustments made by West Point's branching board, 96% of the cadets in the class were placed into one of their top three preferences.

Overall, 80% of the class was placed into a combat arms branch, a 5% increase over last year. For the first time, cyber was considered a combat arms branch along with infantry, armor, engineer, air defense, field artillery and aviation. The 40 cyber spots, up from 25 last year, accounted for almost the entirety of the increase in combat arms spots."

First kidney exchange in Denmark

The first Danish incompatible patient-donor pair has received a transplant in an exchange with a pair in "another Scandinavian country."

Mette skaffede sin mand en nyre ved at sende sin egen til en fremmed
Første dansker har fået en nyre takket være nyt nyrebyttesystem.
[Google Translate: Mette obtained her husband a kidney by sending her own to a stranger
First Danes have got a kidney thanks to a new kidney replacement system.]

"At the Kidney Association, there is great enthusiasm about the new method in kidney transplantation.

- I would go so far as to say that it is a revolution in living organ donation, says the association's vice-president, Malene Madsen.

Right now, there are approximately 400 patients at home who are on a waiting list for a new kidney. And for them it will have a huge effect if the donor chains really get going."

Kidney exchange in Time Magazine

Time celebrates kidney exchange:

Kidney Swaps Are Revolutionizing a Broken Organ-Donation System in the U.S.

"While kidney swaps can be performed at most transplant centers across the U.S., the majority are facilitated by the National Kidney Registry. Other swaps are organized by the United Network for Organ Sharing, the Alliance for Paired Kidney Donation, or arranged in-house at the transplant center itself with incompatible patient pairs."

Aiming for diversity in Brooklyn schools

The Washington Post  has the story:

What happened when Brooklyn tried to integrate its middle schools  By Laura Meckler

"New York City, with more than 1 million students, is far and away the nation’s largest school district — and one of its most segregated. Resistance to integration dates to the 1950s, when mothers in Queens staged an early demonstration against busing.

"Now, in fits and starts, the city is becoming a laboratory of experimentation, examining whether it’s possible to tackle the stratification that courses through urban districts.

"First, Mayor Bill de Blasio (D) tried — and has so far failed — to overhaul the admissions process for eight elite specialized high schools, which admit few black or Hispanic students. He is now considering a recommendation for a citywide plan to eliminate most gifted and talented programs, which attract a disproportionate number of white and Asian students.
...
"Under the old system, criteria set by each school played a big role in deciding who went where. Certain middle schools required high test scores and excellent behavior ratings from elementary school, and affluent families gravitated to them. Over time, various schools won reputations for excellence, and with each passing year, their incoming classes grew whiter and wealthier.
...
"Under the new plan, family preference still matters, but 52 percent of sixth-grade seats at each school are reserved for children from poor families or for those learning English, reflecting the demographics of the district as a whole. The city’s goal is for each school to include 40 percent to 75 percent priority-group students by the program’s fourth year.
...
"This sort of plan is possible only because a significant number of middle-class and wealthy families live in the area covered by the integration plan, Kahlenberg said. If there are too many poor kids, he said, meaningful integration is not possible. By Kahlenberg’s calculations, integration is possible in nine of the city’s 32 school districts.

Others caution that it won’t work anywhere if affluent parents leave the public schools. When Mike Bloomberg was mayor, he worked to attract and keep these families by giving them considerable control over school placement. If you take that power away, these parents may choose private schools or to move, said Joel Klein, schools chancellor under Bloomberg.

“If you look at many urban school districts, you will find they are overwhelmingly minority because the middle class has already moved out,” Klein said."

NYC school choice: long lines for high school tours (and some confusion about first choices)

The high school choice process in New York City uses an algorithm that makes it safe for families to list high schools in their order of preference over them.  But forming well-informed preferences is no easy task.

The NY Times has a story about long lines forming for tours of a desirable public high school:

Why White Parents Were at the Front of the Line for the School Tour
The high stakes of high school admissions in New York — and the lengths some go to get any small advantage.  By Eliza Shapiro

"Parents who pay $200 for a newsletter compiled by a local admissions consultant know that they should arrive hours ahead of the scheduled start time for school tours.

"On a recent Tuesday, there were about a hundred mostly white parents queued up at 2:30 p.m. in the spitting rain outside of Beacon High School, some toting snacks and even a few folding chairs for the long wait. The doors of the highly selective, extremely popular school would not open for another two hours for the tour.

"Parents and students who arrived at the actual start time were in for a surprise. The line of several thousand people had wrapped around itself, stretching for three midtown Manhattan blocks.
...
"Many New Yorkers cannot leave work in the middle of the afternoon, and some students surely did not know that the open house — or even the school — existed in the first place."
**********

The story goes on to talk about the matching system for high schools, which uses a deferred acceptance algorithm.  Parag Pathak points out to me that one paragraph contains a sentence that is easy to interpret incorrectly:

"Beacon, unlike Stuyvesant, does not have an admissions test. But to win a spot, students must have high standardized test scores and grades, along with a strong portfolio of middle school work and admissions essays. Students are much less likely to be accepted if they do not list Beacon as their top choice." (emphasis added)

Parag writes about this line: "while factually correct, the statement creates a misleading impression: a student is only less likely to get Beacon if they didn't list it as their top choice in the case that they were assigned their first choice school instead.  And most people who apply to Beacon list it first because it's their top choice. "

The manner in which the deferred acceptance algorithm (with students proposing) makes it safe for families to state their true preferences can be summarized this way: If you list Beacon as your second choice, and don't get your first choice, then your chance of admission to Beacon is the same as if you had listed it as your first choice.

Of course, even with that guarantee, a family's choice may not be simple if they would have liked to rank order 15 schools, and are only allowed to list 12. Then they have to consider whether, if they are rejected by their first choice, they are likely to be accepted by Beacon, or whether rejection from their first choice is a signal that they might not be competitive at Beacon either. (In which case, listing Beacon as first choice wouldn't have helped...)

Interview with Parag Pathak on schools, and market design

From Business Insider:
Parents choosing high schools for their kids place more value on the students already enrolled than on the school's effectiveness, according to a study by MIT economist Parag Pathak

"A solution to school matching might be attainable, but the bigger challenge remains. "It's a success in terms of matching systems getting out there," Pathak said. "But it shines a spotlight on bigger problem - the scarcity of good schools."
...
"The rise of "market-design economics" has attracted a new type of person to the profession, he said. "Our folks are much more humble. We really like to get our hands dirty from very real problems," he added. "The mindset is more of an engineer — how would we put those ideas to use in actually building something in society?"

Liver Paired Exchange: Ready for Prime Time in North America?

An editorial in the November 2019 Liver Transplantation considers, among other things, how liver exchange might be more coercive than live liver donation, because real or imagined incompatibilities might no longer serve to excuse an ambivalent donor from going through with the donation. (I recall discussions like this at the outset of kidney exchange, and my sense is that, in those days, the doctors thought that they could still excuse ambivalent donors by indicating that they weren't healthy enough to donate...)

Liver Paired Exchange: Ready for Prime Time in North America?
Talia B. Baker M.D

"The evolution of kidney paired exchange (KPE) in the United States has expanded transplant options for ABO‐incompatible and human leukocyte antigen–incompatible living donor pairs.1 The success of KPE has prompted consideration of liver paired exchange (LPE). Although the idea seems promising, its application has been limited to a handful of centers in Asia.2-4
...
"In the United States, approximately 3,000 patients are removed from the liver waiting list each year because they become too ill or die prior to transplant.7 Although living donor liver transplantation (LDLT) is established as the primary source of donor allografts in many parts of Asia, it constitutes approximately only 4% of liver transplants in the United States.7 The potential number of living donor and recipient pairs that might be suitable for LPE in the United States is unknown and largely unexplored.
...
"The indications for LPE are more complex than in KPE where immunological factors drive the process. In LPE, anatomical factors, such as hepatic mass (ie, graft‐to‐recipient weight ratio and percent of future liver remnant), and anatomical considerations, such as arterial and biliary variants, will also importantly be considered.
...
"coercion, which remains one of the greatest ethical concerns for the evaluation of any living donor, will have to be considered in a more robust manner. Concerns about coercion may be exacerbated by indirect exchanges, such as in LPE, because a reluctant or hesitant donor may no longer be able to invoke ABO incompatibility, size, or anatomical incompatibility as a reasonable and accepted way to withdraw from consideration as a living donor.9 ...
"Often, transplant centers are able to select the most willing donors based on their commitment to step forward, expressing unwavering interest and determination to donate. This system inherently allows willing, but ambivalent, donors to be excused based on objective medical measures (most commonly ABO incompatibility or anatomical issues) without having to admit their ambivalence. In contrast, LPE may remove or limit this potential by offering alternative options for exchanges, thereby inadvertently exposing or subjugating ambivalent donors. "

Is repugnance to foie gras contagious?

The Guardian has the story from the UK, focusing on a particular restaurant, and its proprietor, who has withstood protests:

Pressure grows on British chefs after New York bans foie gras
Restaurateurs and MPs are turning against the delicacy after years of intense animal rights protests

"New York’s authorities have decided to ban shops and restaurants from selling it and campaigners want London – indeed, the whole of Britain – to follow suit.

“Banning it is a fad,” he says. “New York is just following a fad, going with the flow. If it is ethically raised, then I don’t see a problem. If they are [forcibly] fed on an industrial scale, I think that’s wrong. But the foie gras we serve comes from a family who look after their geese.”

"His stance is not one that most animal welfare campaigners agree with. Making foie gras generally relies on force-feeding ducks or geese for about two weeks, causing their livers to expand dramatically. Some farmers claim force-feeding – known as gavage – is unnecessary, but in France, where 98% of the foie gras eaten in Britain is made, a pâté can only be called foie gras if gavage is used."
