Deaccessioning art in the time of corona virus--

 Art museums have long frowned on selling art from their collections, and have been frowned upon when they do so. (It used to be not ok to sell art, except to buy different art, but not e.g. to fix the roof over the art...).  That's changing, "temporarily," in response to the financial crisis museums are facing during the coronavirus pandemic.  (It will be interesting to see if the old repugnance prohibitions can be restored later...)

Here's an April story from the Washington Post:

This is how bad things are for museums: They now have a green light to sell off their art

By Sebastian Smee

"To counter the constant temptation to regard art works as a way to get quick cash, the museum world heavily polices the sale of works from permanent collections — otherwise known as deaccessioning. The powerful Association of Art Museum Directors, made up of directors of museums in the United States, Mexico and Canada, has long frowned on any museum that sells off art for purposes other than acquiring new art.

"AAMD’s frowns have an effect. Museums that dare to ignore its guidelines — as the Berkshire Museum in Pittsfield, Mass., did in 2018, ultimately selling more than 20 works from its collection to raise money for a renovation — are censured, sanctioned and publicly shamed. For a renegade — or perhaps simply desperate — museum director, a decision to sell works from the collection, even if it’s to raise money deemed necessary for survival, might mean career death.

"However, in an unprecedented move, and as a direct result of the coronavirus pandemic, the AAMD has recently relaxed its guidelines. It’s too soon to gauge the effect, but it is already big news in the art world. Once unthinkable, the notion of selling off a Claude Monet or two to plug a budgetary hole — or to fend off a total financial meltdown — is suddenly something to contemplate.

"According to AAMD, museums may now “use the proceeds from deaccessioned works of art … to support the direct care” of their collection.

...

"AAMD says it recognizes “the extensive negative effects of the current crisis on the operations and balance sheets of many art museums.” It acknowledges, too, the impossibility of knowing when revenue streams might return to normal.

"The new guidelines are temporary, and are “not intended to incentivize … the sale of art.” But their effect may do just that."

Brooklyn Museum to Sell 12 Works as Pandemic Changes the Rules

Museums selling their art has long been frowned upon, but recent financial pressures have sent works to the auction block at Christie’s. The proceeds would pay for the care of the collection.

Virtual conference on Zero/Minimal Intelligence Agents, October 22 – 24, 2020

 A remarkable 1993 JPE paper by Gode and Sunder showed that random bids and offers constrained only not to be money losing could converge in a sense to competitive equilibrium in double auction markets:

Allocative efficiency of markets with zero-intelligence traders: Market as a partial substitute for individual rationality

DK Gode, S Sunder - Journal of political economy, 1993 - journals.uchicago.edu

We report market experiments in which human traders are replaced by" zero-intelligence" programs that submit random bids and offers. Imposing a budget constraint (ie, not permitting traders to sell below their costs or buy above their values) is sufficient to raise the allocative efficiency of these auctions close to 100 percent. Allocative efficiency of a double auction derives largely from its structure, independent of traders' motivation, intelligence, or
learning. Adam Smith's invisible hand may be more powerful than some may have thought; it can generate aggregate rationality not only from individual rationality but also from individual irrationality.

In October, there's a conference following up on the idea that some market institutions may have desirable properties that don't depend on the rationality of the agents.

Job matching under constraints by Kojima, Sun, and Yu in the September AER

 From the September AER, the latest in a distinguished string of papers initially motivated by aspects of the clearinghouse for new doctors in Japan:

Kojima, Fuhito, Ning Sun, and Ning Neil Yu. 2020. "Job Matching under Constraints." American Economic Review, 110 (9): 2935-47.  DOI: 10.1257/aer.20190780

Abstract: Studying job matching in a Kelso-Crawford framework, we consider arbitrary constraints imposed on sets of doctors that a hospital can hire. We characterize all constraints that preserve the substitutes condition (for all revenue functions that satisfy the substitutes condition), a critical condition on hospitals' revenue functions for well-behaved competitive equilibria. A constraint preserves the substitutes condition if and only if it is a "generalized interval constraint," which specifies the minimum and maximum numbers of hired doctors, forces some hires, and forbids others. Additionally, "generalized polyhedral constraints" are precisely those that preserve the substitutes condition for all "group separable" revenue functions.

Here's the first paragraph:

"Hiring entities often face various types of constraints. In the United States, firms that receive favorable treatments from governments often promise to hire at least a certain number of workers (Byrnes, Marvel, and Sridhar 1999): floor constraints. In Chinese cities, the household registration system distributes quotas to employers for transferring  employees’ registrations from other places (Chan and Zhang 1999): type-specific ceiling constraints on hiring nonlocals. In rural India, a health subcenter is often required to be staffed by exactly one male and one female (Kapoor 2011): type-specific constraints with exact quotas. These are restrictions on the set of employees that an employer is allowed to hire. Inspired by a classical framework for studying job markets (Kelso and Crawford 1982), this paper studies how all possible restrictions of this type impact the substitutes condition on revenue functions of the employers, a condition known to be critical for the existence and certain regularity properties of competitive equilibria (Kelso and Crawford 1982; Gul and Stacchetti 1999; Milgrom 2000; Hatfield et al. 2019; Kojima, Sun, and Yu 2020a)"

and, from the Conclusions section:

"In a classical paper on the difficulty for rural hospitals in filling all of their positions in the National Resident Matching Program, Roth (1986) concludes that “this maldistribution seems unlikely to be changed by any system that does not involve some element of compulsion, or some change in the relative numbers of available positions and eligible students.” Our analysis suggests that in job matching with adjustable salaries, a compulsion in the form of floor or ceiling constraints may be a possible solution: one of the appealing properties of such a policy is that it preserves the substitutes condition and thus the existence of competitive equilibria under standard assumptions (Kojima, Sun, and Yu 2020a)."

On allocating scarce vaccines

 From the NBER working papers this week:

Do Black and Indigenous Communities Receive their Fair Share of Vaccines Under the 2018 CDC Guidelines?

Parag A. Pathak, Harald Schmidt, Adam Solomon, Edwin Song, Tayfun Sönmez, M. Utku Ünver

NBER Working Paper No. 27817   September 2020

Abstract: A major focus of debate about rationing guidelines for COVID-19 vaccines is whether and how to prioritize access for minority populations that have been particularly affected by the pandemic, and been the subject of historical and structural disadvantage, particularly Black and Indigenous individuals. We simulate the 2018 CDC Vaccine Allocation guidelines using data from the American Community Survey under different assumptions on total vaccine supply. Black and Indigenous individuals combined receive a higher share of vaccines compared to their population share for all assumptions on total vaccine supply. However, their vaccine share under the 2018 CDC guidelines is considerably lower than their share of COVID-19 deaths and age-adjusted deaths. We then simulate one method to incorporate disadvantage in vaccine allocation via a reserve system. In a reserve system, units are placed into categories and units reserved for a category give preferential treatment to individuals from that category. Using the Area Deprivation Index (ADI) as a proxy for disadvantage, we show that a 40% high-ADI reserve increases the number of vaccines allocated to Black or Indigenous individuals, with a share that approaches their COVID-19 death share when there are about 75 million units. Our findings illustrate that whether an allocation is equitable depends crucially on the benchmark and highlight the importance of considering the expected distribution of outcomes from implementing vaccine allocation guidelines.

Covid has slowed transplants in the UK

The Evening Standard has the story:

Organ transplant waiting list jumps to five-year high due to pandemic, new NHS figures show

by Naomi Ackerman 

"The number people waiting for an organ transplant has soared to five-year high as a result of the coronavirus pandemic, new NHS figures have shown.

"NHS Blood and Transplant (NHSBT) said this week that an estimated 6,700 people are currently in need of a transplant across the UK - up from 6,138 prior to the start of the pandemic.

"The health body has estimated that the increase in patients waiting - expected to be the highest since 2015-16 - comes after services were impacted by the effects of the pandemic.

...

"It is hoped that the waiting list can be shortened going forward following the introduction of a new law in May, making organ donation "opt-out" rather than an active choice.

...

"The law will see that families are still consulted before organ donation goes ahead - the reason is why health officials have implored people to make their wishes about donation known to their families.

"NHSBT has said that thousands of "transplant opportunities" have been missed in recent years. In 2018-19, it reported that 835 families declined to support organ donation - with many families saying they did not know what their relative would have wanted."

Economies in the Time of Coronavirus (in English and Chinese)

 Here's a short essay I wrote for the Luhohan Academy in June, published on their web site in July in English, and the Chinese translation in the Caixin online magazine.

Economies in the Time of Coronavirus

by Alvin E. Roth

Here's the first paragraph:

"Years from now we will look back on the Covid-19 pandemic as a source of much new information, not just about epidemic disease and how to manage it, but about structural features of the world’s economies that were made clearer by the crisis and how it was handled, both well and badly.  In the meantime, we can begin to speculate about what we will have learned when the pandemic is history, and what we must still learn to prepare for dealing with its continuation, and with future pandemics."

...

here's another paragraph:

"Testing policies will have to keep in mind what economists know well, which is that there may be perverse incentives in play. Some people will be very eager to return to work, and might be willing to do so even when they risk spreading infection. Others may be happy to work from home (especially if there is risk of infection at work) and may not wish to return to work even when they themselves do not pose a risk to others. And if those who have been infected and have recovered  (e.g. who test positive for antibodies) are treated differently than others, some people may feel a need to expose themselves to infection in order to enter this privileged class. So who conducts the tests, and how they are reported and recorded, will be important."

A proposal for non-simultaneous kidney exchange in pairs and chains and with deceased donors...

 Here's an ambitious proposal, that may face  obstacles to implementation, but which provides some clarity about the inefficiencies of current practice.

Unpaired Kidney Exchange: Overcoming Double Coincidence of Wants without Money

Mohammad Akbarpour, Julien Combe, Yinghua He, Victor Hiller, Robert Shimer, Olivier Tercieux

NBER Working Paper No. 27765, September 2020, pdf

Abstract: For an incompatible patient-donor pair, kidney exchanges often forbid receipt-before-donation (the patient receives a kidney before the donor donates) and donation-before-receipt, causing a double-coincidence-of-wants problem. Our proposed algorithm, the Unpaired kidney exchange algorithm, uses “memory” as a medium of exchange to eliminate these timing constraints. In a dynamic matching model, we prove that Unpaired delivers a waiting time of patients close to optimal and substantially shorter than currently utilized state-of-the-art algorithms. Using a rich administrative dataset from France, we show that Unpaired achieves a match rate of 57 percent and an average waiting time of 440 days. The (infeasible) optimal algorithm is only slightly better (58 percent and 425 days); state-of-the-art algorithms deliver less than 34 percent and more than 695 days. We draw similar conclusions from the simulations of two large U.S. platforms. Lastly, we propose a range of solutions that can address the potential practical concerns of Unpaired.

Politics and medicine, at Stanford and in Washington--an open letter from Stanford docs about corona virus policies

 Politics and medicine can combine poorly, particularly in a politicized pandemic.

Here's an open letter from over a hundred faculty at Stanford's Medical school, disowning the positions about pandemic policies taken by one of their former colleagues, now in Washington, by way of Fox News. (Here's the letter in full; to see the signatories click on the link...)

An Open Letter from Stanford Doctors [Update: the letter has been taken down from the Stanford medicine website, but here is another copy...]

"As infectious diseases physicians and researchers, microbiologists and immunologists, epidemiologists and health policy leaders, we stand united in efforts to develop and promote science-based solutions that advance human health and prevent suffering from the coronavirus pandemic. In this pursuit, we share a commitment to a basic principle derived from the Hippocratic Oath: Primum Non Nocere (First, Do No Harm).

"To prevent harm to the public’s health, we also have both a moral and an ethical responsibility to call attention to the falsehoods and misrepresentations of science recently fostered by Dr. Scott Atlas, a former Stanford Medical School colleague and current senior fellow at the Hoover Institute at Stanford University. Many of his opinions and statements run counter to established science and, by doing so, undermine public-health authorities and the credible science that guides effective public health policy. The preponderance of data, accrued from around the world, currently supports each of the following statements:

●  The use of face masks, social distancing, handwashing and hygiene have been shown to substantially reduce the spread of Covid-19. Crowded indoor spaces are settings that significantly increase the risk of community spread of SARS-CoV-2.

●  Transmission of SARS-CoV-2 frequently occurs from asymptomatic people, including children and young adults, to family members and others. Therefore, testing asymptomatic individuals, especially those with probable Covid-19 exposure is important to break the chain of ongoing transmission.

●  Children of all ages can be infected with SARS-CoV-2. While infection is less common in children than in adults, serious short-term and long-term consequences of Covid-19 are increasingly described in children and young people.

●  The pandemic will be controlled when a large proportion of a population has developed immunity (referred to as herd immunity) and that the safest path to herd immunity is through deployment of rigorously evaluated, effective vaccines that have been approved by regulatory agencies.

●  In contrast, encouraging herd immunity through unchecked community transmission is not a safe public health strategy. In fact, this approach would do the opposite, causing a significant increase in preventable cases, suffering and deaths, especially among vulnerable populations, such as older individuals and essential workers.

"Commitment to science-based decision-making is a fundamental obligation of public health policy. The rates of SARS-CoV-2 infection in the US, with consequent morbidity and mortality, are among the highest in the world. The policy response to this pandemic must reinforce the science, including that evidence-based prevention and the safe development, testing and delivery of efficacious therapies and preventive measures, including vaccines, represent the safest path forward. Failure to follow the science -- or deliberately misrepresenting the science – will lead to immense avoidable harm.

"We believe that social and economic activity can reopen safely, if we follow policies that are consistent with science. In fact, the countries that have reopened businesses and schools safely are those that have implemented the science-based strategies outlined above.

"As Stanford faculty with expertise in infectious diseases, epidemiology and health policy, our signatures support this statement with the hope that our voices affirm scientific, medical and public health approaches that promote the safety of our communities and nation."

Here's a recent NY Times story on Dr. Atlas, a radiologist:

A New Coronavirus Adviser Roils the White House With Unorthodox Ideas

Dr. Scott Atlas arrived at the White House as a coronavirus contrarian, questioning controls like masks. He has angered top health officials while pushing a suite of disputed policy prescriptions.

By Noah Weiland, Sheryl Gay Stolberg, Michael D. Shear and Jim Tankersley,  Sept. 2, 2020

"Before joining the task force, Dr. Atlas pitched his ideas as a health commentator on Fox News, which is in part how he attracted Mr. Trump’s attention. His arrival at the White House has coincided with less visible roles for Dr. Birx and Dr. Fauci, the director of the National Institute for Allergy and Infectious Diseases."

**********

Of course, medicine isn't the only kind of science that has been caught up in Washington lately. (I write this from smoky California, where climate change seems quite real).

Nor is it the only part of medicine that has been caught up in politics around the world: I'm reminded of yesterday's post about the politics of global health care.  Science seems to be slowly gaining on politics there, and so I'm hopeful that's a general trend, although sometimes slow and uneven, with a high ratio of heat to light.

Global Kidney Exchange supported by the European Society of Transplantation's committee on Ethical, Legal, and Psychosocial Aspects of Transplantation .

Quite some time ago, the European Society for Organ Transplantation (ESOT) charged its committee on Ethical, Legal, and Psychosocial Aspects of Transplantation (ELPAT) with the task of evaluating those aspects of global kidney exchange (GKE). GKE had been greeted in some quarters with a number of dramatic accusations (e.g. that it was a form of organ trafficking), and the ELPAT committee tried to consider each of them.  Interestingly, the committee included members who I surmise started with a wide range of views, from cautious support to active hostility to GKE.

The final report, just published in Transplant International,  (which is the official journal of ESOT) is one that I think the committee can be proud of.  While you can tell that some committee members retain reservations about GKE, they nevertheless all agreed on a report that finds all of the principal objections raised against GKE to be unfounded.  Together with the even more clearly stated support for GKE in the Lancet, I think that this may mark a turning point: it certainly marks that GKE is receiving growing (and well deserved) support. 

Global Kidney Exchange: opportunity or exploitation? An ELPAT/ESOT appraisal

"Summary: This paper addresses ethical, legal, and psychosocial aspects of Global Kidney Exchange (GKE). Concerns have been raised that GKE violates the nonpayment principle, exploits donors in low‐ and middle‐income countries, and detracts from the aim of self‐sufficiency. We review the arguments for and against GKE. We argue that while some concerns about GKE are justified based on the available evidence, others are speculative and do not apply exclusively to GKE but to living donation more generally. We posit that concerns can be mitigated by implementing safeguards, by developing minimum quality criteria and by establishing an international committee that independently monitors and evaluates GKE’s procedures and outcomes. Several questions remain however that warrant further clarification. What are the experiences and views of recipients and donors participating in GKE? Who manages the escrow funds that have been put in place for donor and recipients? What procedures and safeguards have been put in place to prevent corruption of these funds? What are the inclusion criteria for participating GKE centers? GKE provides opportunity to promote access to donation and transplantation but can only be conducted with the appropriate safeguards. Patients’ and donors’ voices are missing in this debate." 

Here's their introduction:

"In 2017, Rees et al. [1] introduced “Global Kidney Exchange” (GKE), an international kidney exchange program that facilitates cross‐border exchanges between immunologically incompatible donor–recipient pairs in high‐income countries (HIC) and biologically compatible but financially impoverished donor–recipient pairs in low‐ to middle‐income countries (LMIC). GKE aims to overcome immunologic barriers in the developed world and poverty barriers in the developing world. The underlying rationale is that financial barriers prevent transplantation much more frequently than organ scarcity. The number of patients dying annually worldwide from end‐stage kidney disease due to inadequate financial resources far exceeds the number of patients in developed countries placed on kidney transplantation waitlists [1-3]. GKE has the potential to expand the genetic diversity of the donor pool which may help to transplant difficult‐to‐transplant, highly immunized patients [1]."

As they debunk the main arguments that have been made against GKE, I thought that some of these remarks were among the most interesting:

"Removing financial barriers to organ donation is an internationally agreed objective, enshrined, among others, in the World Health Organization’s (WHO) Guiding Principles on Human Cell, Tissue and Organ Transplantation and in the CoE Convention [13, 15]. These organizations highlight that prohibition of organ payments does not preclude reimbursing expenses incurred by the donor, including the costs of medical procedures [13, 17]. Given that countries’ legislation vary in their approach to what constitutes illicit payment versus legitimate reimbursement, it is doubtful whether GKE violates the nonpayment principle under all circumstances. For example, the University of Minnesota’s legal team vetted GKE and agreed to proceed. Other hospital legal teams have followed suit [1]."

...

"“[e]xploitation occurs when someone takes advantage of a vulnerability in another person for their own benefit, creating a disparity in the benefits gained by the two parties” [9]. It is hard to see, however, that this description of exploitation can be readily applied to GKE. Primarily, it is not clear that there is a significant disparity in benefits between recipients. Each patient receives a kidney transplant, and as Minerva et al point out, benefits are arguably greater for LMIC recipients, who get the additional benefit of their follow‐up care being paid for [33]. The same is true for the donors, who each obtain the desired benefit of their intended beneficiary receiving a transplant. Rather than there being a morally troubling disparity in benefit, GKE appears to offer either roughly equal benefit, or greater benefit for those who are allegedly exploited."

"It is also unconvincing to consider GKE exploitative on other grounds. Rather than failing to protect the vulnerable, it seems that GKE addresses specific vulnerabilities by offering protection to those who are (i) vulnerable to death from kidney failure or (ii) vulnerable to losing a loved one due to kidney failure. It is similarly unconvincing to suggest that GKE treats people merely as a means to an end. Instead, one can see that participants in LMIC are respected as individuals, with measures put in place to protect their welfare and to ensure that their participation is voluntary."

...

The claim that donors and recipients in LMIC are too poor or vulnerable to voluntarily engage in GKE is also debatable and could be seen as paternalistic. First of all, the risk that voluntariness is undermined does not apply specifically to GKE or to LMIC alone, but applies to living donation more generally [35].

...

"The proclamation that countries have to be self‐sufficient was first declared by the 2008 DoI and the WHO [73, 74] and has rapidly gained momentum since [75-77]. The argument to ban GKE because of the need to achieve self‐sufficiency raises various implications however. First of all, it implies that the need for countries to become self‐sufficient is more important than the lives that can be immediately saved through GKE. Is achievement of self‐sufficiency so important that it overrides life‐saving alternatives? Who has the authority to decide which approach should get priority? Why is it required that countries become self‐sufficient in organ donation and transplantation, while it is universally accepted for countries to rely on global exchanges of all other types of goods and services?

 ***********************

The ESOT/ELPAT committee apparently operated under rules that prevented them from investigating some claims that required evidence, so they included some questions for us in their paper, which we answer in the comment that appeared in the same issue of TI. (For example, there was some confusion about what escrow meant in connection with the money provided for the foreign donor and recipient's medical expenses after their return home...)

In any event, the large number of co-authors to our comment (21!) is another expression of the broad and international support that GKE is achieving.

Here's the full first paragraph:

"We read with great interest and appreciation the careful consideration and analysis by Ambagtsheer et al. of the most critical ethical objections to Global Kidney Exchange (GKE). Ambagtsheer et al. conclude that implementation of GKE is a means to increase access to transplantation ethically and effectively.1,2 These conclusions by their European Society of Transplantation (ESOT) committee on Ethical, Legal and Psychological Aspects of Transplantation (ELPAT) represent a step forward toward a greater understanding and an open, honest debate about GKE. Taken together with the strong endorsement of GKE by Minerva et al. in Lancet  and the positive position statement of the American Society of Transplant Surgeons (ASTS), Ambagtsheer et al. successfully dispel previously raised doubts 5-13 to which we have previously responded .2,14-17"

Plasma in Canada, and repugnant transactions--a podcast interview

 I was recently interviewed by Kate van der Meer, a Canadian patient affected by the plasma shortage of 2019. Her experience inspired her to look deeper into the plasma supply chain and raise awareness to the negative implications of the Voluntary Blood Donations Act. Part of this awareness campaign is the Plasma For Life Podcast Series, of which this interview is a part.

Fuhito Kojima wins the 2021 Japanese Economic Association Nakahara Prize

 Congratulations to Fuhito Kojima, who is the 2021 winner of the Nakahara Prize of the Japanese Economic Association, which is awarded each year to an exceptional economist under the age of 45.

You can find the announcement (in Japanese) here. Google translate works well, and you can see the list of previous winners.

Here's part of the English announcement (which I can't find on the web...)

"The 2021 Japanese Economic Association Nakahara Prize

Professor Fuhito Kojima

"The Nakahara prize was established in 1995 and is funded by a donation from Mr. Nobuyuki Nakahara. The aim of the prize is to honor and encourage young researchers under the age of 45 to publish internationally recognized research. 

It is a great pleasure to announce that the 2021 Nakahara prize has been awarded to Professor Fuhito Kojima. Born in 1979, Professor Kojima received BA in economics from the University of Tokyo, and earned Ph.D. in economics from Harvard University in 2008. He was Assistant, Associate and then Full Professor of Economics at Stanford University, and he is Professor of Economics at the University of Tokyo from September 2020.

Professor Kojima’s research is focused on matching theory and market design. He has made a number of important contributions to the field. Many of his researches are motivated by various kinds of constraints imposed on matching problems in real life. His research significantly contributes to widening applicability of the theory to real matching markets.

Child marriage in Somalia

 The Guardian has the story:

'A race against time': the new law putting Somalia's children at risk of marriage: Child marriage in the country has increased during coronavirus – and now a newly-tabled bill would allow children as young as 10 to marry   by Moulid Hujale

"According to the latest government figures, 34% of Somali girls are married before they reach 18, and 16% of them before their 15th birthday.

"While children are married off for different reasons, such as the economic benefit of a dowry, and an increase in child marriage cases has been reported during the coronavirus pandemic, early marriage is rooted in Somali culture. An old Somali saying goes: “Gabadh ama god hakaaga jirto ama gunti rag,” which loosely translates as “a girl should either be married or in a grave”.

"Marriage under 18 is not illegal, although Somalia’s constitution prohibits it and the country is signed up to several international treaties promising to tackle it. In July 2014, the government signed a charter committing to end child marriage by 2020. But in August, the Somali parliament tabled a controversial bill that would allow a child to be married once they reached puberty, which can mean 10 years old. The sexual intercourse related crimes bill would also allow marriage if parents consented. The UN has called the bill “deeply flawed”.

Transplant transport: direct commercial flights boost deceased donor transplants, by Wang, Zheng, and Dai

 Alex Chan draws my attention to this paper on airline transport of kidneys for transplant:

Does Transportation Mean Transplantation? Impact of New Airline Routes on Sharing of Cadaveric Kidneys

Abstract

Nearly 5,000 patients die every year while waiting for kidney transplants, and an estimated 18% of procured kidneys are discarded. Such a polarized co-existence of dire scarcity and massive wastefulness has been mainly driven by insufficient pooling of cadaveric kidneys across geographic regions. Although numerous policy initiatives are aimed at broadening organ pooling, they rarely account for a key friction — efficient airline transportation, ideally direct flights, is necessary for long-distance sharing due to the time-sensitive nature of kidney transplantation. Conceivably, transplant centers may be reluctant to accept kidney offers from far-off locations without direct flights. In this paper, we estimate the effect of the introduction of new airline routes on broader kidney sharing. By merging the U.S. airline transportation and kidney transplantation datasets, we create a unique sample tracking (1) the evolution of airline routes connecting all the U.S. airports and (2) kidney transplants between donors and recipients connected by these airports. We estimate the introduction of a new airline route increases the number of shared kidneys by 7.3%. We also find a net increase in the total number of kidney transplants with the introduction of new routes. Notably, the post-transplant survival rate remains largely unchanged, though average travel distance increases after the introduction of new airline routes. Our results are robust to alternative empirical specifications and have important implications for improving access to the U.S. organ transplantation system.
