Abstract

The market for kidney exchange was created to address the shortage of kidneys for donations. The market allows patients with a willing but incompatible live donor to swap donors, so that they can perform transplants, and has grown to about 800 transplants per year. This paper uses detailed administrative data to describe the functioning of this market. The most striking finding is that the market is fragmented into dozens of small platforms instead of working in a single large platform, with most transactions happening in platforms that operate within a single transplant center. This may lead to substantial inefficiency if there are increasing returns to scale to matching patients in a large, thick market.

A Regulated Market for Kidneys

Abstract

The persistent shortage of kidneys for transplantation is a global problem for end-stage renal disease (ESRD) patients. Many countries have tried to address this issue by increasing deceased donation, by introducing kidney exchange programs, and by optimizing the allocation algorithms. Despite such efforts, the problem of shortage is growing in most countries, with more than 100,000 people waiting for a kidney transplant only in the U.S. Iran is the only country in the world that has introduced a different program of living unrelated renal donation, which includes two kinds of monetary compensation of donors: a "gift for altruism" from the government to donors, as well as an additional compensation from the patients themselves. We will discuss the impacts of this program on waiting times, organ shortage, and its equilibrium effects on other kinds of live donation.

Strategic Behavior in the Kidney Waitlist

Abstract

A transplant can improve a patient's life while saving several hundred thousands of dollars of healthcare expenditures. Organs from deceased donors, like many other common pool resources (e.g. public housing, child-care slots, publicly funded long-term care), are rationed via a waitlist. The efficiency and equity properties of design choices such as penalties for refusing offers or object-type specific lists are not well understood and depend on agent preferences. This paper establishes an empirical framework for analyzing the trade-offs involved in waitlist design and applies it to study the allocation of deceased donor kidneys. We model the decision to accept an offer from a waiting list as an optimal stopping problem and use it to estimate the value of accepting various kidneys. Our estimated values for various kidneys is highly correlated with predicted patient outcomes as measured by life-years from transplantation (LYFT). While some types of donors are preferable for all patients (e.g. young donors), there is substantial heterogeneity in willingness to wait for good donors and also substantial match-specific heterogeneity in values (due to biological similarity). We find that the high willingness to wait for good donors without considering the effects of these decisions on others results in agents being too selective relative to socially optimal. This suggests that mild penalties for refusal (e.g. loss in priority) may improve efficiency. Similarly, the heterogeneity in willingness to wait for young, healthy donors suggests that separate queues by donor quality may increase efficiency by inducing sorting without significantly hurting assignments based on match-specific payoffs.

The 1% Steps for Health Care Reform Project (including kidney exchange)

 The goal of the 1% Steps for Health Care Reform Project is to shift the way we think about health care spending in the US and offer a roadmap to policy makers of tangible steps we as a country can take to lower the cost of health care in the US. We want to leverage leading scholars’ work to identify discrete problems in the US health system and offer evidence-based steps for reform. We will continually update the project with new proposals that are based on the latest academic research.

Here is their full list of Policy Briefs.

Here's one on kidney exchange:

Expanding Kidney Exchange

Authors: Nikhil Agarwal, Massachusetts Institute of Technology; Itai Ashlagi, Stanford University; Michael Rees, The University of Toledo Medical Center; Alvin Roth, Stanford University

Here's one paragraph:

"Policy Proposal: This brief discusses three specific proposals for expanding kidney exchange. First, policy makers should eliminate financial disincentives for participating in kidney exchange platforms by including medical and administrative costs specific to kidney exchange in reimbursements from the Medicare program. Second, policy makers should direct the federal contractor UNOS (United Network for Organ Sharing) to allow kidney exchange chains to be initiated by deceased donors. Third, Medicare should pay for the costs of a global kidney exchange that allows exchanges involving patients in different nations."

And here's some discussion by Nikhil Agarwal with Zack Cooper:

A landmark market design paper, on school choice in NYC, by Abdulkadiroglu, Agarwal, and Pathak

When market design was young, it was a game played by game theorists.  As it matured, and we wanted market designs be adopted, implemented, and maintained, it became a kind of economic engineering. But for market design to become a fully mature part of economics, not only must designs move into practice, and be monitored and maintained, they must also be evaluated.*

So I find myself thinking again about this paper from the December AER that I already blogged about:

Abdulkadiroglu, Atila, Nikhil Agarwal, and Parag A. Pathak, “The WelfareEffects of Coordinated Assignment: Evidence from the New York City High SchoolMatch,”American Economic Review, 107(12), December 2017, 3635–3689.

I think of it as the third of three papers: the first two were about the engineering aspects of the NYC high school match, the first school choice design of its kind:
Abdulkadiroglu, Atila , Parag A. Pathak, and Alvin E. Roth, "The New York City High School Match,American Economic Review, Papers and Proceedings, 95,2, May, 2005, 364-367.
and
Abdulkadiroglu, Atila , Parag A. Pathak, and Alvin E. Roth, "Strategy-proofness versus Efficiency in Matching with Indifferences: Redesigning the NYC High School Match,'' American Economic Review, 99, 5, Dec. 2009, pp1954-1978. 

Now, in this third paper, two of the original designers (Abdulkadiroglu and Pathak) together with one of the new generation of market design investigators  (Agarwal) evaluate the impact on students of the current centralized school choice system (it uses a deferred acceptance algorithm) in comparison to the decentralized ("uncoordinated") system it replaced.  

The new system produces a stable matching, which good evidence suggests is helpful in keeping the system healthy in the long term in a school system like NYC, in which the school principals are also strategic players.  But aside from being long lasting, how good is the system for students?

Using the (ordinal) rank order lists submitted by students in the new system, the paper measures welfare by estimating a cardinal random  utility model, with (cardinal) tradeoffs among school attributes being measured in terms of the additional distance a student is willing to travel to be at a more preferred school.

The uncoordinated system suffered from congestion, with many students having to be placed administratively in a school for which they had expressed no preference.  They find that these schools were by and large significantly less desirable.

They find that the new system improves welfare over the old by 80% of the gains that could be achieved by a utility-maximizing allocation made independent of other constraints. They further find that changes in the algorithm (e.g. choosing a different stable matching, among the multiple that arise from random tie-breaking) would have very little effect on welfare.

The biggest difference is that under the old system, only about half the students were placed in the "main round" (now occupied by the deferred acceptance algorithm), whereas in the new system this number immediately climbed to over 80% (with some additional subsequent gains). So students who used to be administratively assigned are now largely assigned instead to a school over which they have expressed a preference. That turns out to be very good for them.

Market design is coming of age...
###########

* Of course, not all steps in the market design process have to be accomplished by the same individuals, but in this case that's an extra plus.  And of course other  school choice markets have been investigated by these and other investigators, but in most cases those markets were not designed by economists, so that's another extra bonus here too, especially since features of the design (which encourage truthful reporting of preferences) add to the ability to estimate welfare gains.

The welfare effects of centralized school choice in NYC, by Abdulkadiroglu, Agarwal and Pathak in the AER

The Abdulkadiroglu, Agarwal and Pathak paper on the effects of school choice in NYC has now come out in the December 2017 AER ( 107(12): 3635–3689).

They find substantial welfare effects in moving from NYC's old decentralized high school choice system (in which individual schools made uncoordinated acceptance decisions, so some students received multiple offers while others got none) to the stable matching system (using the deferred acceptance algorithm with single tie-breaking) now used. They don't find big gains from trying to reach a student optimal stable matching by revising the tie-breaking decisions.

The Welfare Effects of Coordinated Assignment:Evidence from the New York City High School Match
By Atila Abdulkadiroglu, Nikhil Agarwal, and Parag A. Pathak

"Coordinated  single-offer  school  assignment  systems  are  a  popular  education  reform.  We  show  that  uncoordinated  offers  in  NYC’s  school  assignment  mechanism  generated  mismatches.  One-third  of  applicants were unassigned after the main round and later administratively placed at less desirable schools. We evaluate the effects of the new coordinated mechanism based on deferred acceptance using estimated student preferences. The new mechanism achieves 80 per-cent of the possible gains from a no-choice neighborhood extreme to a utilitarian benchmark. Coordinating offers dominates the effects of further algorithm modifications. Students most likely to be previously administratively  assigned  experienced  the  largest  gains  in  welfare  and subsequent achievement."

Topics in Market Design: Econ 287/365: Winter quarter, Itai Ashlagi

Itai Ashlagi will be teaching Econ 287 this quarter, on topics in market design.  It's highly recommended.

He writes that the syllabus below is very tentative, and will depend in part on how many of the enrolled students took Econ 285 (Ostrovsky and Roth) in the Fall (back in 2023:-)

Topics in Market Design 2024, Itai Ashlagi

Market design is a field that links the rules of the of the marketplace to understand frictions, externalities and more generally economic outcomes. The course will provide theoretical foundations on assignment and matching mechanisms as well as mechanism design. There will be emphasis on theories at the intersection of economics, CS and operations as well as applications that arise in labor markets, organ allocation, platforms.

The class will further expose students to timely market design challenges and will we will host a few guest lectures. The class offers an opportunity to begin a research project. Students will reading critique papers, present papers and write a final paper.
