Mike Rees in India to help remove obstacles to kidney exchange

The Times of India reports:
Paired kidney donations may mitigate patients’ agonizing wait

"On Tuesday, at an event organized by Gift Your Organ Foundation, Dr Michael Rees, CEO, Alliance for Paired Kidney Donation, USA, and Dr Eric Velez, founder of ProRenal, a Mexico-based organization, discussed the possibilities of paired kidney transplants that can be a solution for Indian patients. The duo played key roles in making the world's first-ever global paired transplant possible.
...
"The US, in 2017, brought required amendments to its National Organ Transplant Act (NOTA) to allow paired donations. Alliance for Paired Kidney Donation has a transplant matching software that does the matching between donors and recipients.

"In Mexico, 1.2 lakh people suffer from end-stage renal disorder and only 2600-2800 patients undergo transplants every year, said Dr Eric Velez.

"Shalini Rajneesh, principal secretary, health and family welfare, said Alliance for Paired Kidney Donation agreed to share their software with the Jeeva Sarthakate Society of Karnataka (earlier known as ZCCK) for free. The state-owned society works on organ transplants and coordinates with patients awaiting organs through the registry. "The software does a perfect match between donors and recipients to allow the swap transplant," she said.

"Asked if the legal framework allows live kidney donation between unrelated donors, she said as a long-term plan, the government will look into the issues and bring in required amendments. The main barrier is people do not want to donate and there is a need to create awareness, she added.

"Currently, transplants among unrelated donors are put through a series of checks to ensure that it does not lead to kidney racket.

'Transplants between spouses getting tougher'

"Dr Sankaran Sundar, a nephrologist who has coordinated more than 2,500 transplants so far, said the existing legal framework makes it difficult for patients to pursue transplants among unrelated donors.

"Karnataka has seen only six swap kidney transplants. Even among the spousal donors (when the couple want to share a kidney), it's been difficult to get approval from the authorization committee. When the kidney transplant is between a father/mother and son/daughter, or between siblings, it's easy to establish relationship. But when it is between a couple, it's tough, as marriage certificate has also been found to have been doctored in many cases," said Dr Sankaran Sundar."

The threshold structure of Top Trading Cycles (TTC) by Leshno and Lo

A new look at top trading cycles:

The Simple Structure of Top Trading Cycles inSchool Choice
Jacob D. Leshno and Irene Lo  April 25, 2017

Abstract: "Many cities determine the assignment of students to schools through a school choice mechanism. The prominent Top Trading Cycles (TTC) mechanism has attractive properties for school choice, as it is strategy-proof, Pareto efficient, and allows school boards to guide the allocation by specifying priorities. However the combinatorial description of TTC makes it non-transparent to parents and difficult for designers to analyze. We give a tractable characterization of the TTC mechanism for school choice: the TTC assignment can be simply described by n^2 admission thresholds, where n is the number of schools, and these thresholds can be easily observed after running the mechanism. To calculate these thresholds, we de fine TTC through trade balance equations. In a continuum model these equations correspond to a differential equation whose solution can give closed form expressions for the admission thresholds.

The model allows us to compute comparative statics, and evaluate welfare. As applications of the model we solve for optimal investment in school quality, explore the design of the priority structure, and provide comparisons between TTC and other school choice mechanisms that help explain empirical findings. To validate the continuum model we show that it gives a good approximation for strongly converging economies. Our analysis draws on an interesting connection between continuous trading procedures and continuous time Markov chains."

School choice in Chicago: GoCPS

Here's an account from New Schools for Chicago:
Chicago Board of Education Approves the Single Application
"Yesterday, the Chicago Public Schools Board of Education voted unanimously in favor of moving to a single application for all public high schools in the city. This decision comes just after a recently released report from the Institute for Innovation in Public School Choice (IIPSC) and New Schools for Chicago outlining the feedback and recommendations of parents from across the city. "
**********

And here's a news story from WTTW:

"The Board of Education voted unanimously Wednesday to approve a new common application for students entering district high schools this fall. The new model, called “GoCPS,” is aimed at transparency and efficiency in that application process, according to CPS Chief Education Officer Janice Jackson.

“We cannot have a system that allows some people to feel that they can access with ease while others feel like it’s too complicated and choose to disengage," she said. "So moving forward, GoCPS allows us to bring more people into the fold, but it also allows us an opportunity to use technology to support them.”

In the current system, students can fill out multiple applications and receive offers from high schools.

With GoCPS, students will fil out a single application, rank their school choices and receive a maximum of two offers – one each from a selective and non-selective school. If they choose to reject those offers, students would go through the process a second time and receive new offers.

If those too are rejected, the student would be placed in their neighborhood school with the option to apply for a transfer within the first 20 days of the school year."

Paul Milgrom on the history of spectrum auctions


How obscure science led to spectrum auctions that connected the world
BY PAUL MILGROM,  04/30/17 07:00 AM EDT

"The incentive auction I helped design is an innovation building on decades of economic theory research on auctions dating back to the Nobel-prize winning work of William Vickrey and to work by my own research advisor, Robert Wilson, in the 1960s with funding from the Atomic Energy Commission. What interest did this Cold War era agency have in theoretical auctions? Well, nothing, but they were highly interested in advancing the field of game theory – a then obscure branch of mathematics used in economics that aims to understand how individuals strategize and act in competitive situations.


Over more than 30 years, Wilson, I, and others continued to advance this seemingly esoteric field, until the FCC issued its first proposed rulemaking on developing a spectrum auction that referenced our work. Together with Preston McAfee, who had independently been developing similar ideas, we worked with the FCC to design the first spectrum auction in 1994. The simultaneous multiple round auction we invented has since been used for dozens of spectrum auctions here and around the world. Collectively, these have been called the greatest auction in history, delivering more than $60 billion for the federal government since the early 1990s and enabling the robust wireless communications we enjoy today.

In 2014, the three of us received a Golden Goose Award for our work in this obscure field of social science and its unexpected application to spectrum auctions. None of us envisioned such an auction when we began our study, we were driven by a curiosity in human behavior and markets, not data flying around the country. But the auctions we designed have nonetheless helped change the way we all communicate, consume media, and do our work.

The auction that closed last month was the first of its kind, both because it was two-sided, engaging both TV broadcasters as sellers and mobile operators as buyers, bidding in a single auction, and because the choices of which TV broadcast rights to buy and how to reassign continuing broadcasters needed to respect more than a million constraints to avoid interference among uses. Designing such a complex process brought together a new generation of researchers in both economic and computer science.

When the dust had settled, we were able to repurpose channels 38-51 from broadcast TV uses to free 70 megahertz of spectrum for the growing mobile broadband sector (plus 14 megahertz for wireless microphones). This will enable continuing innovation in broadband and bring better coverage to rural communities. The auction also raised nearly $20 billion in revenue, with more than $7 billion to federal coffers to be used for debt reduction.

Our work on auction design is just one example of how research that may sound obscure or even silly has often benefited society. The Golden Goose Award was founded five years ago to celebrate stories like ours, and it has recognized colleagues of mine like Al Roth whose studies of how to make perfect marriage matches now informs medical residency assignments and kidney exchanges, among many other researchers. In each case, a small investment of federal money returned huge benefits to our nation. And all led to outcomes the researchers never would have predicted when they started."

The 28th Jerusalem School in Economic Theory: Mechanism Design, June 27 - July 6, 2017

The 28th Jerusalem School in Economic Theory

Mechanism Design

Event date: June 27 - July 6, 2017 

Organizers:
    Eric Maskin, General Director (Harvard University)
    Elchanan Ben-Porath, Codirector (The Hebrew University)
    Stephen Morris (Princeton University)



    Mechanism design is the “reverse engineering” part of economic theory. Normally, economists study existing economic institutions and try to predict or explain what outcomes the institutions generate. But in mechanism design we reverse direction: we start by identifying the outcomes we want and then ask what institutions could be designed to achieve those outcomes. The theory has found wide application in auction design, pollution control, public good provision, and elsewhere.

Israel transplant investigation

The Israeli organization Matnat Chaim (Gift of Life), founded by Rabbi Yeshayahu Heber, is under investigation about whether it encouraged families to contribute to the organization in order to receive a shorter waiting time for a kidney transplant.

Organ donor organization suspected of moving donors to head of line for money
Police currently investigating an organization specializing in organ donor mediation, on suspicion of receiving money to provide donors with organs before others in line for transplants.
Omri Efraim & Rotem Elizera|Published:  31.03.17 , 15:06

"Israel Police is carrying on an investigation into Matnat Chaim, an organization that helps find organ donations for those in need of a transplant. The investigation is centered on claims that the organization charged for a "donation" intended to push forward those who paid it, despite there being other people in front of them in line waiting for the same organ donation.
...
"The police stressed that the investigation is a very delicate one, involving people who are suspected of paying the extra fee out of a wish to facilitate a vital transplant that for a member of their family.

Matnat Chaim stated that "We know nothing about the investigation carried against (the organization—ed), and so we do not find it necessary to respond." The organization has so far aided in some 400 transplants in Israel. It only works with organ donors wishing to donate organs for zero pay."
**********
Here's another story with a bit more detail:

Police launch inquiry into kidney transplant organizationCops investigating claims that Matnat Chaim bumped patients to top of recipient list in exchange for donations

"The probe follows a complaint from the Health Ministry that recipients were bumped to the top of the list in exchange for donations to the organization.

Police have taken evidence from organ recipients, their families and other sources in the ongoing investigation.

A police spokesperson explained that the investigation was complex and sensitive. The organization is suspected of encouraging relatives of those in need of transplants to make donations to the organization in order to shorten the waiting time to receive a kidney.
...
"Over 400 healthy people have donated a kidney through the organization.
...
"In the past, the organization has said that it had never agreed to accept donations in exchange for promoting a patient in the waiting list. It said that “it completely rejects any suggestion of any hint of wrong-doing.”

Talking to nephrologists about kidney exchange

Most conversations about kidney exchange (aka kidney paired donation, kpd) are with transplant professionals. But kidney patients start out being referred to a nephrologist, and so it was good to be able to talk to nephrologists at the recent meeting of the National Kidney Foundation.

My talk was about how kidney exchange has made a lot of progress, and become a standard part of transplantation, but that there's still room for it to grow and help more patients get transplants.   In that regard I focused on two recent initiatives, starting a non-directed donor chain with a deceased donor kidney, and global kidney exchange to bring developing world patient-donor pairs into American kidney exchange to the mutual benefit of both kinds of pairs.

Here's a news story from Nephrology News (with a headline that unfortunately disses the many pioneers of kidney exchange):

Father of kidney exchange says it’s time for a refresh

And here's a story that focuses on starting kidney exchange chains with a deceased donor kidney, from the Dutch Nier nieuws (Kidney news)

'Start donatieketting met overleden donor'
("Start donation chain with deceased donor")

Organ transplantation in Iran

Robert Gutman draws my attention to this article from the English language Iranian Financial Tribune:  Sunday, April 23, 2017 Strides in Organ Transplant

I'm not sure where the claim in the first sentence of 50,000 organ transplant "surgeries" comes from, but the rest of the article (which seems to talk about a total closer to 5,000 transplants) is an interesting view of the situation in Iran.


"Over 50,000 organ transplant surgeries were conducted during the last fiscal year that ended on March 20.
Around 2,500 kidney, 802 liver, 119 heart, 30 pancreas and several intestine and lung as well as 1,040 bone marrow transplants were performed in Iran during the period, said Seyyed Mohammad Kazemeini, head of the Organ Transplant Management Office at the Health Ministry.
“This impressive number of transplant surgeries has helped save many lives as well as more than $1.8 billion in foreign exchange, as patients would otherwise have paid huge amounts for the medical help abroad. Some were even treated free,” the official was quoted as saying by ISNA.
However, he regretted that insurance companies still refuse to cover expenses of organ transplants despite a government directive last year.
“Insurance companies are not complying and the Health Ministry has to draw on its own resources to provide free services for some patients,” he said and hoped the ministry’s support would continue.
“During this year’s New Year holidays (March 21- April 2), 93 transplants were performed,” which shows the preparedness of the medical fraternity.
Iranian organ transplant teams are capable of providing assistance and training to neighboring countries, he said.
Last year a team of experts from Mashhad, capital of the northeastern Khorasan Razavi Province, carried out 47 renal transplants in Afghanistan, and medical teams from Shiraz, capital of the southwest Fars Province, conducted 20 operations in Pakistan and Tajikistan.
Shiraz University of Medical Sciences is known for its accomplishments in liver transplants and the hospitals under its coverage are among the top medical centers in the world with regard to the number of surgeries performed. On average, 500 liver transplants and 300 kidney surgeries are annually undertaken in Shiraz, which also has the distinction of performing the first kidney transplant in Iran in 1968 at the prestigious Namazi Hospital.
A specialized hospital is now planned to be established in Shiraz for organ transplants.
Iran ranks third worldwide in organ donation and is the only country in the world that has addressed the shortage of transplant organs through a legal payment system since 1988 when living non-related donation (LNRD) was legalized,  making it the only country where organ sale is legal.
There are currently 46 organ transplant centers in the country and 25 facilities for organ donation.
  Increase in Brain-Dead Organ Donation
According to Kazemeini, people’s tendency to donate organs of brain-dead patients in their families has increased significantly.
“Last year, 57% of transplant kidneys were donated by brain-dead patients,” he said.
In the past organ donation or sale by living people was predominant. The acceptance of organs of brain-dead patients has improved remarkably due to legal and religious decrees and widespread awareness campaigns on the issue.
Organ transplant is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ.
Today, over 1.4 million people have voluntary organ donation cards in the country. On average, 700 organ donations (nine per million people) are made annually according to official statistics.
Organs that have been successfully transplanted include heart, kidney, liver, lung, pancreas, intestine, and thymus. Worldwide, kidneys are the most commonly transplanted organs, followed by liver and heart. Organ donors may be living, brain dead, or dead via circulatory death.
In the fiscal year that ended in March 2016, from among the 8,000 people confirmed as brain dead at Iranian hospitals, 1,400 kidneys (and 2,300 organs) were donated.
Kidney transplants account for nearly 75% of all organ replacement surgeries while liver and heart transplants comprise 22% and 3% of the total number. More than half of all transplanted kidneys (56%) were from brain-dead donors and 44% were from living people.
Kazemeini had earlier pointed to Iran’s top position in the field of kidney transplant in the Middle East. On average, 3,000 kidney transplants are conducted every year and Iranian surgeons have transplanted over 35,000 kidneys so far."

Market design at Harvard Business School

Here's the announcement of a new HBS course on market design:

Making Markets

Course Number 1764
Professor Thomas R. Eisenmann
Associate Professor Scott Duke Kominers
Spring; Q3Q4; 3 credits
24 sessions
Paper
Markets are everywhere - and where they’re not, you can build them!

Career Focus

Over the past twenty years, entrepreneurs have created and captured enormous value by launching new marketplaces. Examples include Airbnb, Alibaba, ClassPass, Craigslist, eBay, eHarmony, Etsy, Gerson Lehrman Group, Google, IEX Group, Lending Club, Kickstarter, OpenTable, Rakuten, Uber, Upwork, and many more.
Making Markets (M²) is intended for students who want to manage in marketplace environments and remedy market failures by building new platforms and marketplaces from scratch or by redesigning existing ones - or who want to advise or invest in entrepreneurs who pursue such opportunities.

Educational Objectives

Students will learn how to identify market failures and determine when those failures create opportunities to launch or redesign marketplaces.
First, we will explore how markets function and what makes them fail. Next, we will examine how effective marketplace design-or redesign-can address market failures and improve efficiency, liquidity, and fairness. Then, we will take the entrepreneur’s perspective, studying the key barriers to organizing new marketplaces and devising strategies for overcoming them. Along the way, we will pay special attention to settings in which marketplaces create more value for transaction partners than relying only on unmediated exchanges. As we will see, marketplace design can often “square the circle,” solving seemingly intractable problems simply by reducing transaction costs or barriers to entry.
Case contexts will range from ultra-local (e.g., the HBS EC course lottery) to truly global (e.g., container shipping); will examine private and public/social enterprise settings; will profile both online and offline marketplaces; and will span all stages of marketplace launch and development.

Course Content

Through case studies, simulations, and the occasional interactive lecture, M² will examine the design, launch, and management of marketplaces and marketplace platforms. Core lessons include:
  • The Structure and Purposes of Markets: Markets create value by enabling parties to execute mutually beneficial transactions - exchanging goods, say, or sharing ideas. They are everywhere that transacting parties face incentives - from classic contexts like financial or product markets to dating, recruiting, and the sharing economy.
    Some markets are completely unstructured, but most are subject to at least some rules that shape participation. In this course, we will focus in particular on markets that are organized through marketplaces that combine rules for participation with infrastructure to facilitate interactions and transactions.
  • Common Sources of Market Failure: In many markets, institutional frictions combine with incentives to produce suboptimal outcomes - socially wasteful transactions occur, or productive ones do not. When such market failures occur, entrepreneurial opportunities arise: reshaping the market to improve efficiency creates value that can be captured(!).
    To understand how to fix markets, however, we must first understand how and why market failures occur. The course will classify different types of market failures, and highlight entrepreneurial responses to each.
  • Strategies for Launching and Managing Marketplaces: When launching a marketplace or other market intervention, it is essential to mobilize a critical mass of market participants so that there is enough liquidity for valuable transactions to occur. Once running, a marketplace must maintain balance between its supply and demand sides, or else participants may leave to transact elsewhere. Yet at the same time, marketplaces must avoid crowding that makes it hard for participants to find high-value transaction partners.
    The course will provide strategies for promoting participation and trust in marketplaces, especially early on. Then, we will learn techniques for growing marketplaces, and combating the problems that marketplaces face at scale, such as congestion, “unraveling” (e.g., when recruiters pressure candidates with early and exploding offers), and the risk of disintermediation.
  • Types of Marketplace Mechanisms: Markets work in many different ways. Some compel participants to seek out their own transaction partners; others use centralized transaction discovery and execution systems like auctions and recommendation algorithms. The mechanisms that a marketplace uses to identify and process transactions can be the difference between success and failure.
    Choosing among marketplace mechanisms requires careful attention to market participants’ needs and transaction attributes. The course will provide guidelines for adopting mechanisms best suited for different market contexts.

School choice in Indianapolis: podcast of my talk at the Economic Club of Indianapolis

Here's a link to the broadcast of my talk on radio WYFI in Indianapolis, on markets, marketplaces, Who Gets What, and school choice with unified enrollment which is coming to Indianapolis next year.
