Dealing with shortages of deceased donors in a future with fewer automobile accidents

Sometimes you find out that someone has already worried about something that you haven't even thought of worrying about.  I worry about some aspects of transplantation, and I sometimes think about driverless cars, but here's an article about a worry that is nowhere near the top of my list.  However the short article below (it's a comment on another article) raises some interesting points about how society may want to rethink increasing organ donation as we see (I hope) ever fewer deaths from automobile accidents:

How Do You Donate Life When People Are Not Dying: Transplants in the Age of Autonomous Vehicles

Zoe Corin, Roee Furman, Shira Lifshitz, Ophir Samuelov & Dov Greenbaum (2018) , The American Journal of Bioethics, 18:7, 27-29, DOI: 10.1080/15265161.2018.1478024

"While there are differences of opinion as to when autonomous or self-driving cars will actually invade our roads—some car manufacturers are predicting consumer-ready self-driving cars as early as 2021—there is broad consensus that their inevitability is assured. And while there are clear positive social consequences that will result from self-driving cars and trucks, there are also a number of often less appreciated negative externalities. Balanced against the saved lives, minimized commutes, reduction in pollution, and general decrease in daily stress are the driving-related job losses and the reality that there will be fewer organ donors."
...
"There are no quick fixes, and current laws already place significant restrictions on the organ acquisition process. Buying and selling organs is nearly universally objectionable, unethical, and illegal (Ludin 2008). Some countries even ban any benefit, or any form of valuable consideration whatsoever, in exchange for an organ (Caulfield et al. 2014
Caulfield, T.E. NelsonB. Goldfeldt, and S.Klarenbach2014Incentives and organ donation: what’s (really) legal in Canada?Canadian Journal of Kidney Health and Disease 1: 7.[Crossref][PubMed], [Google Scholar]). Some jurisdictions go even beyond this altruistic-only donor requirement, and allow live donations only among blood relatives (India 1994Government of India. 1994. Transplantation of Human Organs Act, 1994.http://wwwmedindianet/tho/thobill1asp. [Google Scholar]).
...
"However, even these universal attitudes have some specific exceptions: In many countries, blood donors are paid, and sperm and egg donors can receive thousands of dollars in remuneration. But just because a handful of tissue donations have been commodified (albeit sometimes obfuscated as gifts with financial consideration), it is not clear that this cash for contribution system will expand anytime soon to include other types of living donations, such as liver lobes or kidneys. To wit: While New York sperm donors can make more than a thousand dollars a month (Lewinnov 2016
Lewinnov, T201610 things to know about being a sperm donor, New York Times, Nov. 3 2016. [Google Scholar]), surrogacy contracts are still void and unenforceable by law (New York 2014New York. 2014. N.Y. Dom. REL. Law §§ 121-124 Surrogate Parenting Contracts Organ Donation and Recovery Improvement Act (2004). [Google Scholar]).
Nevertheless, in light of the need for organs, a number of jurisdictions have tried to indirectly incentivize donation, either through financial or non-financial mechanisms. Such incentives include paying for funeral costs of non-living donors, or for the out-of-pocket expenses directly associated with transplantation (US 2004)."

The King and Lloyd (in special issue of Games and Economic Behavior in Honor of Lloyd Shapley)

Games and Economic Behavior has published a
Volume 108, Pages 1-614 (March 2018)

The first paper in the special issue is this Introduction



Introduction to the special issue in honor of Lloyd Shapley: Eight topics in game theory

David's introduction concludes with "Some remembrances of Lloyd," by various authors.  Here is mine: 


The King and Lloyd
By Alvin E. Roth

My first long conversation with Lloyd was when I visited him in 1974, having just finished my Ph.D. dissertation. I made what felt like a pilgrimage to see him at the RAND Corporation in Santa Monica, to tell him about my work.  

My last long conversations with Lloyd were in December, 2012, when we both attended the Nobel Prize celebrations in Stockholm. A careful observer might have noted that we had both aged a little since our first meeting. Lloyd walked with a cane, and that led to a small bit of logistics.

When you receive the Nobel from the King of Sweden, the King presents you with two packages, containing the diploma and the medal, which you hold with your left hand so that the two of you can shake hands. Lloyd was concerned about how he would manage this with his cane, and so we agreed that I would walk with him and hold his cane while he received the packages and shook hands, and return it to him immediately afterwards. Hence the picture below.



A subsequent encounter with the King had a touch of game theory. The night after the awards ceremony (and a very big dinner party in the City Hall) there is another dinner party in the royal palace, followed by a reception. At some point Lloyd was fatigued and ready to return to the hotel. But royal protocol dictates that no one should leave before the King, and that when the King leaves the party is over, and everyone leaves. So if the King had been told that one of his guests of honor was ready to go home, he would have felt obliged to depart and end the party to make this possible. To avoid ending the party prematurely, Lloyd therefore exited through the kitchen with the help of palace staff, without passing by the King and without alerting him and disrupting the party.  I thought it very appropriate that he exited with this small game-theoretic flourish.

How storks became non-kosher

When I speak about repugnant transactions--transactions that some people would like to engage in but others think they shouldn't--I don't normally include dietary restrictions of a religious sort, like those which make food kosher or hallal (or vegetarian or vegan) since those restrictions are normally applied by people to themselves, not to others.  Thus most observant Jews don't think that non-Jews should keep kosher, and many vegetarians think that what you eat is a matter of personal preference.

However, within a religious community, what is allowed can be a matter of public discussion.  Haaretz has a (late breaking) account of the discussion of storks, in medieval Spain.  Perhaps storks aren't kosher because of a translation error?

How Rashi Got the Jews to Stop Eating Storks
A young rabbi in medieval Spain, scandalized by local laxness, sparks a bitter battle over bird on the plate
By Elon Gilad Jul 30, 2018

"During the second half of the 11th century, Rashi labored on his commentary of the Bible and the Babylonian Talmud, which became and still are highly influential. It was in these that Rashi identified the khasida with the stork, apparently for the first time.

Rashi could not read Arabic and was thus cut off from the traditions of the Geonim. He based his commentary of the oral tradition he received from his teachers, and his own power of logic.

With regard to the identity of the 20 unclean birds listed in the Bible, Rashi apparently did not receive a precise identification of each one. He writes in his commentary that the anafa, the bird coming right after the khasida in the list, was a heron - “I think.”

He may have been more certain regarding the khasida, since he doesn’t qualify that its identification was based on conjecture, but it probably was.
...
The influence of Rashi’s commentaries was immense. Once Rashi identified the khasida with the stork, this became the traditional view among European Jews with in just a few generations. Over time this tradition spread throughout the Jewish world, and into Christian vernacular translations of the Bible.

The identification of the khasida with the stork began to spread throughout Spanish Jewry as we have seen with the arrival of Asher ben Jehiel and his family at the turn of the 14th century, and Spanish Jews gradually stopped eating the bird.

When the Jews of Spain were expelled in 1492, they took the ban on stork to Jewish communities throughout the Arabic-speaking world, and these communities too stopped eating storks. Eventually all Jews accepted Rashi’s identification of the biblical khasida with the stork and today all Jews accept that storks are not kosher."

Presumed consent: too early to declare failure, but cautions are plentiful

Frank McCormick points out a recent report in the journal Health Policy indicating that the Welsh move from opt-in to opt-out or ('deemed consent') for deceased organ donation has not so far been successful at raising transplant rates:

Welsh 2013 deemed consent legislation falls short of expectations
by Jordan Alexander Parsons

"Abstract: Wales, in 2013, was the first country in the United Kingdom to pass legislation introducing presumed (or deemed) consent for organ donation, and remains the only one. It was introduced in an attempt to increase the number of life-saving transplants taking place in the UK, in a move that policy makers hoped would mirror Spain’s success. More recently, pressure has been mounting for England to follow suit, with a public consultation currently in progress. However, the Welsh system has been far from a success, raising the question of why campaigners are so adamant that it should be replicated. Before the Welsh Government introduced the Human Transplantation (Wales) Act there had been no strong evidence to suggest it would make a difference, with countries boasting both high organ donation rates and presumed consent legislation demonstrating no clear causal relationship between the two facts. In addition, a recent report evaluating the Act has highlighted its failure to improve donation rates, and has even presented some potentially concerning statistics that may suggest a negative impact. This paper first considers presumed consent in other countries – Spain and Brazil – before illustrating the underwhelming progression of Wales’ new system and the need to look to other options."

Here's a paragraph that strikes me as important, because family consent is important in Wales, and automatic inclusion on the deceased donor registry reduces the signal value that the deceased wished to be a donor:

"Under the Welsh system, the deceased is deemed to have consented to donation unless (1) a decision as to donation by the deceased is in force, (2) the deceased had appointed a person or persons to make the decision on their behalf, or (3) a relative of friend of long standing objects on the basis of views held by the deceased and it is reasonable to assume the objection is accurate [2]. It is down to the medical team to determine whether a relative’s objection is their own, or one based on the views of the deceased. Unsurprisingly, doctors have not shown willing to challenge these objections, despite their legal right to; they consider it inappropriate to go against the wishes of the family."
**************

Here is a related article, which raises other potential problems:
Presumed consent will not automatically lead to increased organ donation
Sharif, Adnan
Kidney International , Volume 94 , Issue 2 , 249 - 251

"a review of the latest available data (2016) from the Global Observatory on Donation and Transplantation suggests no significant difference in overall transplantation activity between presumed versus explicit consent countries, with increased deceased organ donor rates balanced by decreased living donor rates among presumed consent countries (Table 1). Whether the consent process is presumed or explicit has no bearing on many inter-related factors that influence organ donation rates. For example, Coppen et al.4 observed a strong correlation between mortality rates and organ donation numbers (Spearman’s r = 0.81, P < 0.01) and that, after controlling for differences in relevant mortality rates, there was no significant influence of presumed versus explicit consent on organ donation rates."

Blockchains, smart contracts, and incomplete contracts (and Prysm Group, a startup consulting firm on all that)

There's a lot of talk lately about smart contracts, i.e. contracts written in executable code, but less talk about how all contracts are incomplete (and therefore subject to renegotiation, dispute resolution and issues of residual control), a subject for which Oliver Hart won a recent Nobel.


So I was glad to see this article in Forbes:

Nobel Prize Winner Joins Blockchain Startup To Fix Smart Contracts
by Michael del Castillo

"Long before blockchain was cool, Nobel Prize-winning economist Oliver Hart was into contracts. As far back as 1976, the doctor of economics from Princeton University had been exploring how corporations use contracts to interact, and what happens when things go wrong."

The article is sparked by the fact that Oliver and Preston McAfee, who recently retired from being Chief Economist at Microsoft, have become advisors to a startup consulting company called Prysm Group, which aims to advise blockchain companies about contracts, incentives, and economics generally.

Here's the press release:

"Prysm Group provides blockchain organizations with counsel in the complex economic fields of contract theory, market design, game theory, and social choice."

The founders of Prysm Group are two economists who I met when they were graduate students at Harvard, Cathy Barrera and Stephanie Hurder (who I've blogged about before, here, and here).

Welfare in a behavioral world

This is a behavioral economics intensive week at Stanford, with the experimental SITE session just ended, and the Psychology and Economics session underway.

There are a lot of hard problems in behavioral economics: in some senses, it's harder to figure out what people may do if we aren't perfectly rational. But a particular problem is how we should take care of each other, if it isn't always clear how to evaluate someone's welfare.

For example, we had two talks in the earlier SITE session on paternalism--under what circumstances can we make people better off by giving someone else the power to make choices for them?  More generally, if people aren't always good at making choices, how can we tell what's good for them, i.e. how can we evaluate welfare?

Doug Bernheim and Dmitry Taubinsky tackle this question in a chapter in the forthcoming

Handbook  of  Behavioral  Economics,  Volume  1, edited by B.  Douglas  Bernheim,  Stefano  DellaVigna,  and  David  Laibson.

You can find it here as an NBER working paper:

Behavioral Public Economics
B. Douglas Bernheim, Dmitry Taubinsky
NBER Working Paper No. 24828
Issued in July 2018


"This chapter surveys work in behavioral public economics, emphasizing the normative implications of non-standard decision making for the design of welfare-improving and/or optimal policies. We highlight combinations of theoretical and empirical approaches that together can produce robust qualitative and quantitative prescriptions for optimal policy under a range of assumptions concerning consumer behavior. The chapter proceeds in four parts. First, we discuss the foundations and methods of behavioral welfare economics, focusing on choice-oriented approaches and the measurement of self-reported well-being. Second, we examine commodity taxes and related policies: we summarize research on optimal corrective taxes, the efficiency costs of sales taxes that are not fully salient, the distributional effects of sin taxes, the use of non-price policies such as nudges, the tax treatment of giving, and luxury taxes. Third, we examine policies affecting saving, including capital income taxation, commitment opportunities, default contribution provisions for pension plans, financial education, and mandatory saving programs. Fourth, we detail the manner in which under-provision of labor supply and misunderstandings of policy instruments impact optimal labor income taxation and social insurance. We close with some recommendations for future work in behavioral public economics."

Repugnant prediction markets on a blockchain (Augur)

Augur is a decentralized (i.e. unmoderated) prediction market, built on a blockchain.  Somewhere there is a fundamental law of internet that says that anonymity leads to bad manners, and for a prediction market, that means death pools.

Here's the story from CCN, a news service that focuses on cryptocurrencies and blockchains:

Assassination Markets Let Augur Users Gamble on Trump Murder

"this market exists, and, though not the most popular bet on Augur, more than 50 shares have been traded on it as of the time of writing. Similar markets, moreover, exist for a number of other public figures, allowing users to gamble on whether 96-year-old actress Betty White and U.S. Senator John McCain — who has been diagnosed with brain cancer — will survive until Jan. 1, 2019."

Deceased donor chains: Market design language is entering transplantation

Here's some more argument in favor of starting kidney chains with deceased donors, from the journal
Clinical Transplantation Volume 32, Issue 7:

Lessons from Uber and Airbnb: Why we should link the deceased and living donor pools

by Avi Baskin  Ariella Maghen  Tom Mone  Jeffrey Veale

"Deceased donor organs are currently underutilized and undervalued, particularly in kidney chains, similar to how parked cars and vacant homes were before Uber and Airbnb. The ride‐sharing company Uber has been hailed for allowing people to drive their cars to generate more benefit from this underutilized resource. Similarly, Airbnb enables people to rent out their unused property, increasing the potential of an otherwise missed opportunity. Together, Uber and Airbnb represent a new era, amplifying the benefit of cars and property that would be otherwise underused.

"Likewise, the world of transplantation should take note as software programs and mathematical algorithms could also be applied to maximize the benefits of available kidneys for transplant."
*********

The authors are all transplant professionals, not an economist among them. We've come a long way from the days when it was hard to convince the transplant community that kidney transplantation, and kidney exchange in particular, could be usefully thought about in connection with markets, marketplaces, and market design.

Two bills aimed at increasing the number of transplants

The Niskanen Center has a post on two proposed pieces of legislation (together with some thoughts on why incremental policy oriented work is important):

TWO NEW BILLS WILL HELP WITH THE KIDNEY SHORTAGE. BUT PAYING DONORS COULD HELP EVEN MORE.
BY SAMUEL HAMMOND

Here's the  first paragraph of their article, and the  last.


"Last week, the Organ Donation Clarification Act was released by Rep. Matt Cartwright (D-PA) with 14 cosponsors. The bill would clarify the National Organ Transplant Act’s (NOTA) definition of “valuable consideration,” making it clear that donors can be compensated for medical expenses and lost wages. It would also permit the U.S. government to run pilot programs to test the viability of noncash rewards to incentivize donors. And now this week, Rep. Tom Rice (R-SC) has announced a set of amendments to NOTA that seek to orient the Health Resources and Services Administration toward increasing organ procurement, rather than simply distributing an inadequate supply."

...
"At the same time, the Niskanen Center’s overall mission eschews ideal theories in favor of pragmatic policy change. Thus, as much as I’d love to see someone like Al Roth appointed as the organ transplant czar, with a mandate to design an optimal market in organs, politics is a long game of persuasion and compromise. That’s why the two new bills from Reps. Cartwright and Rice remain immensely important, even if they don’t nearly go far enough."

Interview on market design and repugnance with Yale sophomore Eric Wallach

Here's the transcript of a recent telephone interview I did with , a sophomore at Yale, for The Politic, Yale’s undergraduate journal of politics and culture.

 An Interview with Alvin Roth

Here's the one Q&A he chose as a highlight, at the top of the page:

"How do you approach issues that may be ethically constrained? Do you think there’s a way to minimize the value judgements you make as an economist?
It’s interesting you ask the question that way. For a long time, economists seemed to agree with the implicit assumption of your question that we should minimize the ethical judgements we make. I’m not sure that’s a universal position anymore. Among economists, there’s some discussion that maybe we should be taking ethical positions about some of the markets we see, and especially with repugnant markets."

Transcripts of conversations are a bit disorganized, but this interview covered some issues  different from the ones I normally get asked about (and it's short).

Politico summarizes the Backpage story

Here's an article for those who haven't been following this first amendment/prostitution/human trafficking story...

The Sex-Trafficking Case Testing the Limits of the First Amendment
How a couple of crusading journalists made a fortune selling adult escort ads and in the process became unlikely and widely reviled First Amendment advocates.
By PAUL DEMKO July 29, 2018

Many of the people quoted focus on the motivations of the protagonists (get rich, versus defend the First Amendment press freedoms...). I wonder what role if any those questions will play in the legal proceedings.


Here are my other posts about  Backpage and related matters.

How to split the check using social skills or mechanism design

The Washington Post ran a column yesterday that offers advice on
How to split the check without the accusations and awkwardness.

The article points out that restaurants' point of sale software can help if you alert the waiter before you order.

For other fair-division problems, here's a website, Spliddit , that offers tools (and the underlying references to the literature) to help:


If your problem meets the assumptions of the underlying model, you can take it from there.

This seems to be a project of Ariel Procaccia and various colleagues, with Hervé Moulin   as an advisor.

He has another site, RoboVote, which seems more like a general social choice tool for aggregating information or preferences.
