Debate on kidney exchange in Germany

On Friday in Berlin I found myself in a debate with the chairman of the Research Committee of the Bundestag, the German Parliament, about legalizing kidney exchange in Germany. I proposed that a minimal amendment of the law, which now only allows close relatives to donate, would be to also allow them to be the intended donors of their close relatives in kidney exchange. However it doesn't seem as if this is going to happen anytime soon (it looks like only the Free Democratic Party in inclined to support it...)

The medical newspaper ärztezeitung has the story
Transplantation
Lebendspende breiter aufstellen
Beim Thema Organspende rücken die Lebendspenden zunehmend in den Fokus. Ein Nobelpreisträger befeuert die aufkommende Debatte.
[Widen living donation
With regard to organ donation, living donations are increasingly coming into focus. A Nobel Prize winner fuels the emerging debate.]

"Nobel laureate Professor Alvin Roth submitted on Friday morning a proposal on how the living donation of kidneys in Germany could be broadened. Instead of considering only first and second degree relatives, spouses, registered partners and close friends as potential donors in the transplantation law, the pair organ exchange of living donors should also be possible, he said at the Nobel Prize Dialogue of the Leopoldina in Berlin. The aim of this model is to increase the chances of being able to mediate compatible organs to dialysis-dependent patients.

"The chairman of the Research Committee of the Bundestag, Ernst Dieter Rossmann (SPD) advised in his reply to not overburden the population in Germany. First, the contradiction solution must be introduced and its effect on the donor numbers to be waited, he warned.

"At the end of October, the Greens warned against commercialization and organ trade if the so-called cross-donation was introduced. At the FDP, the considerations have fallen on fertile ground."

Rank order voting in NY (and in xkcd)

Vox has the story:
New York City adopts ranked-choice voting, a major milestone for the reform
The biggest city in the US is joining a voting reform movement.

"New York City has become the latest — and most populous — city to adopt ranked-choice voting, a major milestone for voting reform efforts.

Voters in the city overwhelmingly approved Ballot Question 1 on Tuesday, enabling voters to begin using ranked-choice voting in local primary and special elections beginning in 2021.

New York City joins 20 other cities around the country, as well as multiple states, that have already started using this method in various elections. Maine, notably, implemented ranked-choice voting for the first time in a federal election in 2018.

Ranked-choice voting works much like its name suggests. Instead of picking just one candidate on the ballot, voters rank their top five in order of preference.

Once those votes are cast, they are counted in the following way, Lee Drutman explains:

Ranked-choice voting lets voters mark their first-choice candidate first, their second-choice candidate second, their third-choice candidate third, and so on. Each voter has only one vote but can indicate their backup choices: If one candidate has an outright majority of first-place rankings, that candidate wins, just like a traditional election.

But if no candidate has a majority in the first round, the candidate in last place is eliminated. Voters who had ranked that candidate first have their votes transferred to the candidate they ranked second. This process continues until a single candidate gathers a majority."

Lifetime medical insurance for kidney donors?

Reason has the story:

New York Might Compensate You for Your Kidney
But it's just health insurance, not cash
LIZ WOLFE 11.6.2019

"On Friday, New York State Sen. James Skoufis (D–Woodbury), introduced a bill that would provide kidney donors with free health insurance for life. Skoufis' bill, S.B. 6827, would establish a kidney donor insurance fund from which the payouts would come. The new incentives would not apply retroactively to people who have already donated kidneys.

"In New York State, there are 8,006 individuals who are candidates for a kidney transplant as of October 2019, but in 2018 just 521 people in the state who chose to serve as live kidney donors," Skoufis notes in the bill's memo. "Clearly, additional incentives are required to encourage people to give the gift of life."

von Neumann award to Susan Athey

Susan Athey is the recipient of the 2019 John von Neumann Award.

"The John von Neumann Award, named after John von Neumann is given annually by the Rajk László College for Advanced Studies (Budapest, Hungary), to an outstanding scholar in the exact social sciences, whose works have had substantial influence over a long period of time on the studies and intellectual activity of the students of the college. The award was established in 1994 and is given annually. In 2013, separately from the annual prize, Kenneth J. Arrow was given the Honorary John von Neumann Award."

Controversial markets, at Humboldt University

This evening I'll be speaking at Humboldt University:

BSE Lecture on "Controversial markets" by Nobel Laureate Alvin E. Roth

Wann: 07.11.2019 von 14:30 bis 15:45

Wo: Humboldt-Universität zu Berlin, Dorotheenstraße 24, 10117 Berlin, Fritz-Reuter-Saal, 3rd floor

Abstract:Markets need social support to work well. So do bans on markets, since without sufficient social support, bans can be ineffective and can sometimes lead to active black markets. I’ll describe some examples of how these tensions have played out differently in different places, for example, for markets for surrogacy, prostitution, and drugs. A particular example will be the almost (but not quite) universal ban on monetary markets for kidneys, and how this has influenced the treatment of kidney disease and the organization of kidney transplantation around the world, including the development of kidney exchange, which is growing worldwide, but is effectively banned in Germany by current German transplant law.

"If you want to attend the lecture, please register by giving the subject "Registration BSE Lecture Alvin Roth" as well as your name and your institution via email to veranstaltungen@hu-berlin.de.

"After the lecture, at 16:00, up to 25 students (Master's and PhD) as well as Postdocs will have the opportunity to attend a round-table discussion with Alvin Roth in which he will address your questions. This round-table discussion will be held at room 2070a at HU's main building (Unter den Linden 6, 10117 Berlin)."
************

Tonight I'll also speak at an event organized by the Einstein Institute, concerning how changes in the current German transplant law could make kidney exchange practical in Germany.

MIT celebrates Nikhil Agarwal

Optimizing kidney donation and other markets without money
MIT economist Nikhil Agarwal analyzes the efficiency of markets that match suppliers and consumers but don’t use prices.

“In economics,” Agarwal says, “we often [assume] there’s the demand, the supply, the price, and the market clears, somehow. It just happens.” And yet, he says, “That’s not how a lot of markets work. There are all these different important markets where we do not allow prices.”

Scholars in the field of “market design,” therefore, closely examine these nonfinancial markets, observing how their rules and procedures affect outcomes. Agarwal calls himself a specialist in “resource allocation systems that do not use prices.” These include kidney donations: The law forbids selling vital organs. Many education systems and entry-level labor markets, for example, also fit into this category. "

I've followed Nikhil's work for a long time--here are some other posts that mention his work.

Unraveling and (lack of) self confidence by Dargnies, Hakimov and Kübler

Online, in Management Science, a behavioral look at unraveling via early exploding offers:

Self-Confidence and Unraveling in Matching Markets
Marie-Pierre Dargnies , Rustamdjan Hakimov, Dorothea Kübler
Published Online:22 Oct 2019https://doi.org/10.1287/mnsc.2018.3201

Abstract
We document experimentally how biased self-assessments affect the outcome of labor markets. In the experiments, we exogenously manipulate the self-confidence of participants in the role of workers regarding their relative performance by employing hard and easy real-effort tasks. Participants in the role of firms can make offers before information about the workers’ performance has been revealed. Such early offers by firms are more often accepted by workers when the real-effort task is hard than when it is easy. We show that the treatment effect works through a shift in beliefs; that is, under-confident agents are more likely to accept early offers than overconfident agents. The experiment identifies a behavioral determinant of unraveling, namely biased self-assessments. The treatment with the hard task entails more unraveling and thereby leads to lower efficiency and less stability, and it shifts payoffs from high- to low-quality firms.

Kidney donation in Israel

In Israel, as in the U.S., a lot of living kidney donations to strangers come from people associated with faith based organizations. Tablet Magazine has the story:

TO SAVE A STRANGER’S LIFE
Kidney donations are on the rise among Orthodox Israelis
By Sara Toth Stub October 28, 2019

"Koplovich is among the growing number of religiously observant Israelis who are volunteering to donate kidneys to people they have never met, ultimately doubling the number of kidney transplants taking place in the country each year. Officials credit the increase in living donors to improved surgical techniques, increased social welfare benefits, and the work of a nonprofit organization called Matnat Chaim, which raises awareness about and facilitates live kidney donations, especially among Orthodox Israelis.
...
"Rabbinic authorities, whose often stringent definitions of brain death have led to Israel’s relatively low rate of organ transplants from deceased people, are now actively encouraging live donations of kidneys, the most in-demand organ, especially as the danger to the donor has been reduced, according to recent research by Koslowsky, and nephrologists Walter Wasser and Geoffrey Boner, published in the journal BMC Nephrology.
...
"Two Jewish organizations in the United States, Kidney Mitzvah and Renewal, also raise awareness about and facilitate live kidney donation/
...
"All kidney donations and transplant pairings made through Matnat Chaim are overseen by the government-appointed National Committee for Kidney Donations, which also makes sure there is no commercial component involved.

"But donors coming through Matnat Chaim can choose the characteristics of their recipient, and most Jewish donors choose to donate to a fellow Jew. Although bioethicists are generally divided over directing organs to certain types of people, Israeli health officials allow the practice, saying that it has helped increase the overall number of kidneys available.
...
"While Miran Epstein, a medical ethicist at Queen Mary University of London, acknowledges that every donated kidney ultimately helps everyone waiting for a kidney, he said an organization that allows donors to stipulate certain characteristics of potential recipients—including religious affiliation—in effect practices conditional organ donation, which Israel and many other countries don’t allow. When accepting matches made through Matnat Chaim, the government-run transplant system is undermining its own ethics guidelines and public trust, he said: “The ethnic-religious condition is effectively concealed behind the fiction of directed donation. There is no doubt that Matnat Chaim has shortened the waiting list, but the question is, at what price?”

"Meanwhile, Ashkenazi said that the country’s kidney exchange program—where relatives and friends of those in need of a kidney, but who don’t match, donate to a stranger, whose family or friends in turn donate to their relative—often brings together Jewish and Arab donors and recipients."

Egon Balas, 1922-2019

I only now learned that Egon Balas passed away in March, at the age of 96.

I last saw him in 2017, full of energy at an IFORS conference in Quebec City. We became friends in Pittsburgh, where he was the leader of the OR community at CMU.

He came to operations research in the second half of his life, after an incredibly dramatic first half. Here's a link to his CMU obituary:

March 19, 2019, Remembering Egon Balas

"His early life included two imprisonments—one for joining the communist party to oppose the Nazis during World War II and the second by the communist party after the war in a Stalinist purge. He later became one of the world’s foremost experts in mathematical optimization after joining Carnegie Mellon in 1967."

Here's the WSJ obituary:

Egon Balas, Jailed and Tortured in Romania, Found Salvation in Math

After losing his faith in Marxism, academic discovered a genius for devising algorithms and solving business problems

And here's the obit from the Pittsburgh Post Gazette:

Video Interview: Peter Singer on Global Kidney Exchange

Peter Singer discusses Global Kidney Exchange, and his recent article in the Lancet, in this interview on the Practical Ethics blog at Oxford.

Video Interview: Peter Singer on The Global Kidney Exchange Programme
Published November 1, 2019 | By Katrien Devolder

"In this interview with Katrien Devolder, Peter Singer defends the Global Kidney Exchange (GKE) programme, which matches donor–recipient pairs across high-income, medium-income, and low-income countries. The GKE has been accused of being a form of organ trafficking, exploiting the poor, and involving coercion and commodification of donors. Peter Singer refutes these claims, and argues that the GKE promotes global justice and reduces the potential for people in need of kidneys in low-income and medium-income countries to be exploited."

Global Kidney Exchange in the Lancet, by Minerva, Savulescu and Singer

And you can find all my posts on global kidney exchange here.

Update: and here's the press release for the Lancet article, from Princeton's University Center for Human Values:
Peter Singer makes the case for Global Kidney Exchange Program
Thursday, Oct 31, 2019

"Professor Peter Singer is one of three bioethicists who have published an argument in The Lancet, one of the world’s leading medical journals, in favor of a Global Kidney Exchange program that matches donors and recipients across low and middle-income (LMIC) countries with pairs in high income countries.

Singer co-authored the paper with Oxford University Professor Julian Savulescu and Francesca Minerva, a postdoctoral fellow at the University of Ghent, in Belgium.

The three argue that, far from representing a form of organ trafficking, as some critics have suggested, a Global Kidney Exchange program would reduce suffering and save the lives of rich and poor patients alike."

No more foie gras in New York City

The NY Times has the story:

Foie Gras, Served in 1,000 Restaurants in New York City, Is Banned
Animal cruelty concerns led the City Council to approve the ban, which takes effect in 2022. One chef’s reaction: “What’s next? No more veal?”

"The New York City Council overwhelmingly passed legislation on Wednesday that will ban the sale of foie gras in the city, one of the country’s largest markets, beginning in 2022.

New York City will join California in prohibiting the sale of foie gras, the fattened liver of a duck or goose, over animal cruelty concerns."

Global Kidney Exchange in the Lancet, by Minerva, Savulescu and Singer

Here's a clear-eyed account of Global Kidney Exchange, from three moral philosophers, forthcoming in The Lancet. You can read the whole thing at the link:

The ethics of the Global Kidney Exchange programme
Francesca Minerva, Julian Savulescu, Peter Singer
The Lancet (online first, Published:October 29, 2019 DOI:https://doi.org/10.1016/S0140-6736(19)32474-2 )

Summary: The Global Kidney Exchange (GKE) programme seeks to facilitate kidney transplants by matching donor–recipient pairs across high-income, medium-income, and low-income countries. The GKE programme pays the medical expenses of people in medium-income and low-income countries, thus enabling them to receive a kidney transplantation they otherwise could not afford. In doing so, the programme increases the global donor pool, and so benefits people in high-income countries by improving their chances of finding a donor match. Nevertheless, the GKE has been accused of being a form of organ trafficking, exploiting the poor, and involving coercion and commodification of donors. We refute these claims, arguing that the GKE promotes global justice and reduces the potential for people in need of kidneys in low-income and medium-income countries to be exploited. Misguided objections should not be allowed to prevent the GKE from realising its potential to reduce suffering and save the lives of rich and poor patients alike.

*************
The article is very clearly written, it is well worth reading the whole thing.

In a related announcement at the University of Melbourne, Professor Singer and his colleagues have a summary (with pictures):

MAKING THE CASE FOR THE GLOBAL KIDNEY EXCHANGE
The Global Kidney Exchange, which aims to expand the kidney donor pool, has been criticised as ‘organ trafficking’, but the counter argument is that it will save the lives of rich and poor patients alike

By Professor Julian Savulescu and Professor Peter Singer, University of Melbourne, and Dr Francesca Minerva, University of Ghent

"Our paper, published in the medical journal The Lancet, provides an ethical defence of the program.

"GKE has been compared to organ selling, a practice considered immoral by many and illegal in most places. However, as nobody gets paid for giving up their kidney through the GKE programme, this comparison does not hold true"

NCAA takes steps to allow college athletes to be compensated

Here's the NY Times:

N.C.A.A. Considers Loosening Rules for Athletes Seeking Outside Deals
The governing body for college sports appeared to soften its long-held stance that athletes should not profit from their fame. But it gave no details and said any rule changes required much more discussion.

"ATLANTA — The N.C.A.A. Board of Governors, under increasing pressure from legislatures around the country, voted Tuesday to pave the way for college athletes to profit off their fame, but the decision came with an elephant-size caveat: Any policy changes must maintain clear distinctions between amateur athletes and professional ones.

The vote was a surprising turn by the N.C.A.A., which for years has resisted calls for athletes to be compensated for the use of their names, images and likenesses. The board was responding to a report from a committee studying the issue and was expected to do little more than give the committee extra time to do its work.

The N.C.A.A. president, Mark Emmert, acknowledged that the passage of a bill in California that would permit sponsorships, the emergence of more than a dozen others like it nationwide and calls for change from prominent athletes like LeBron James had nudged his organization into action."

Interviews in the Medical Physics residency match (too many, and what to do about it..)

Medical physics has a residency match, and like other residency matches it is suffering from (apparently) too many interviews.

Here's a signed editorial in the Journal of Applied Clinical Medical Physics (one correlate of it being an editorial rather than a paper is this:
"Received: 4 September 2019 | Accepted: 5 September 2019")

Some considerations in optimizing the Medical Physics Match
by Richard V. Butler1, John H. Huston1, George Starkschall2
1Department of Economics, Trinity University, San Antonio, TX,
2Department of Radiation Physics, The University of Texas MDAnderson Cancer Center, Houston, TX

"In 2018, 79% of graduates of CAMPEP‐accredited graduate programs were accepted into residency programs.4 Consequently, to ensure a match, candidates interview at many programs. There is also a harmful feedback mechanism here. As applicants apply to more programs, the acceptance rate at each program declines. Consequently, applicants may apply to even more programs to increase their perceived probability of acceptance into a program. This is costly for the candidates in terms of travel expenses, and costly for the interviewing faculty in terms of time away from research, clinic, and teaching.
...
"Because the problem of optimal applications is an economics problem, there has been a search for solutions and a developing literature on the subject. Balter et al.5 show that limiting the number of applications candidates can submit is superior to limiting the number of applications a program can evaluate. Entering an application limit into the Gale/Shapley algorithm that underlies the matching process, the authors conclude that "the optimal limit in the number of applications balances the tradeoff between being unmatched and gaining a better match in the aggregate, and the benefit can be considerable if the graduates'preferences over the positions are not very correlated.
...
"Another approach to a solution is "signaling." A program would be permitted to notify a small number (somewhere between three and five) of applicants prior to interviews that it is seriously interested in them. This gives the applicant useful information about his/her chances at that particular program and so makes the benefit function a bit less fuzzy. Because the problem in medical physics seems to be more at the interview stage than the initial application stage, some form of signaling by institutions offering residencies might help reduce uncertainty so that at least some applicants could focus on the places where they have good chance and pass on visits to some of their more marginal options."

Organ and tissue procurement: back and forth between LA Times and OneLegacy

Even in the era of social media, it remains difficult to conduct an argument with someone who buys ink by the truckload.

The LA Times ran a series of stories on tissue procurement:
Full Coverage: The Times’ investigation into how companies that harvest body parts upend death investigations

This was followed by a press release from OneLegacy, the big S. California organ procurement organization (OPO), disputing a number of points and objecting to the overall tone of the articles:
Inaccurate and Sensationalized Los Angeles Times Article Likely to Cause Unnecessary Deaths and Suffering
"—A highly-inaccurate and tragically sensationalized article in a recent edition of the Los Angeles Times is likely to lead to deaths and suffering while causing severe damage to the donation and transplantation community."

and this in turn was followed by a rejoinder in the LA Times:
OneLegacy issued a statement on an L.A. Times investigation; The Times responds
By MELODY PETERSEN OCT. 27, 2019
"“The Times stands firmly behind these important stories, which were the product of months of meticulous reporting and careful editing,” said Scott Kraft, managing editor of The Times."

Ed Green, 1948-2019

Ran Shorrer at Penn State passes on the news that his colleague Ed Green died Saturday morning after a long fight with cancer. Ed and I were colleagues at the University of Pittsburgh in the late 1980s. He was a scholar's scholar and a gentle man.

Perhaps his most famous paper is Green and Porter (1984), which outlined how cartels could effectively coordinate on high prices even when they could only imperfectly monitor one another, by engaging in price wars when defection was suspected:

ECONOMETRICA: JAN 1984, VOLUME 52, ISSUE 1

Noncooperative Collusion under Imperfect Price Information

https://doi.org/0012-9682(198401)52:1<87:ncuipi>2.0.CO;2-6
p. 87-100

Edward J. Green, Robert H. Porter

Recent work in game theory has shown that, in principle, it may be possible for firms in an industry to form a self-policing cartel to maximize their joint profits. This paper examines the nature of cartel self-enforcement in the presence of demand uncertainty. A model of a noncooperatively supported cartel is presented, and the aspects of industry structure which would make such a cartel viable are discussed.

Ed also has a series of papers with his wife, Ruilin Zhou.

Interview with Péter Biró on kidney exchange and related matters

The interview touches on Peter's history, and on developments in kidney exchange.

Az algoritmus, ami életeket ment - interjú Biró Péterrel
[Google Translate: The algorithm that saved lives - interview with Péter Biró ]

Google translate gives a pretty readable version...

" Unfortunately, Hungarian colleagues are very busy with their basic tasks, so despite their good intentions, they can devote little resources and attention to creating a Hungarian kidney exchange program. Since 2016, there has been a so-called COST Action program in Europe, which promotes European networking on kidney exchange. I recently visited an economist in Padua on this topic and went to a leading nephrology surgeon there. We talked about how the Italian system could be improved and agreed to test the practicalities of this with the Padua data. By the way, this center carries out most of the living donor kidney transplants in Italy."

Auction results: Nobel medals of John Nash and Reinhard Selten

The auction is over, and (unlike in some previous auctions) all of the items sold. The highest profile items, namely the Nobel medals and diplomas, went for $735,000 (Nash) and 225,000 (Selten).
