Forges, Haeringer and Iehle on matching

Appariement: des modeles de Lloyd Shapley a la conception de march es d'Alvin Roth.

Francoise Forges ,  Guillaume Haeringer,, Vincent Iehle

Here's the English summary:


Matching: from Lloyd Shapley's models to Alvin Roth's market design.

Summary
Alvin Roth and Lloyd Shapley have received in 2012 the Sveriges Riksbank prize in economic sciences in memory of Alfred Nobel, for their work on the centralized organization of some economic markets, which rely on the matching of agents of two different types (students and schools, for instance). Shapley is the co-author, with David Gale, of the seminal paper of the area, which proposes an algorithm to reach a stable matching. Roth directed the reform of the entry level labor market for American physicians (the National Resident Matching Program) and the design of a market for kidney transplants. After having surveyed these contributions, we also give an account of Shapley's leading role in game theory.

Yan Chen chosen president-elect of Economic Science Association

Here's the announcement from the University of Michigan (one will come from the ESA after the international meetings in Zurich this summer):
Yan Chen chosen president-elect of Economic Science Association

Professor Yan Chen has been chosen as the president-elect of the Economic Science Association (ESA), a professional organization devoted to using controlled experiments to learn about economic behavior.

Experimental methods allow researchers to control economic institutions, information, policies, and other important variables, both in the laboratory and in the field. Experiments have provided important information about economic behavior in a variety of subdisciplines of economics, including game theory, consumer behavior, industrial organization, public finance, and labor economics.

The ESA membership includes economists interested in the results of such experiments, as well as scholars in psychology, business, political science, and other related fields. The association publishes a quarterly journal, Experimental Economics, sponsors conferences, and maintains online discussion groups for its members.

The president-elect serves for two years, followed by two years as president. Among Chen’s responsibilities as president will be the planning of the annual meeting and oversight of the association’s journals. She is currently a member of the association's executive committee, serving a three-year term which was to end in 2015.

The association’s current president, Al Roth, won the Nobel Memorial Prize for economics in 2012.

New in Iran: Donate one of your kidneys to be exempted from military service

There's a new development regarding kidney donation and sales in Iran. Google translate renders the headline Donate one of your kidneys to be exempted from military service

I am assured on good authority that the story says that kidney donors will be exempted from military service.

Here's how Google Translate renders the story:

"Acting Human Resources department Stadkl Armed Forces exemptions from military service the soldiers announced the donor organ. According to ISNA, General Moussa Kamali on donor exemption from military service, said the donor organ to make it happen efficiency, We'll exempt him from military service. According to him, for example, people who donate one of his kidneys has been the inclusion of medical waivers are exempt from military service. Stadkl Armed Forces Acting Human Resources department stating Srfdashtn donation card member, was not the reason for exemption from military service, said those who donate their organ, even during military service are exempt from military service."

Economic rewards to motivate blood donations, by Lacetera, Macis and Slonim

This just out in Science: Economic rewards to motivate blood donations. It suggests that old conclusions need to be revisited based on new evidence.

"The position and guidelines of the World Health Organization (WHO) and several national blood collection agencies for nearly 40 years have been based on the view that offering economic incentives to blood donors is detrimental to the quantity and safety of the blood supply (1). The guidelines suggest that blood should be obtained from unpaid volunteers only (2). However, whether economic incentives positively or negatively affect blood donations (and other prosocial activities) has remained the subject of debate since the positions were established (2–8).

"Evidence consistent with the WHO position came originally from uncontrolled studies using nonrandom samples and, subsequently, from surveys and laboratory studies indicating that economic incentives can “crowd out” (decrease) intrinsic motivations to donate and can attract “worse” donors (9). This evidence arguably affected policies, such as bans on compensation for blood and organ donations in many countries.
...
"With a few early exceptions based on small, nonrepresentative samples (12), field trial evidence on how economic incentives affect blood donations has been absent. But field-based evidence from large, representative samples has recently emerged. The results are clear and, on important questions, opposite to the uncontrolled studies, surveys, and laboratory evidence preceding them."
...
"Conclusion

"In light of the recent evidence, it is time to re-examine policy guidelines for increasing and smoothing blood supply, including whether incentives can play a role. There are efforts under way from different parts of society toward using rewards to increase donations. The U.S. 9th Circuit Court of Appeals' 2012 ruling legalizing compensation for bone marrow donations through apheresis was initiated by private individuals (32). A company prompted a 2010 European Court of Justice ruling that allowed importation of blood products obtained from compensated donors (33). Researchers and clinicians have noted that some WHO guidelines (e.g., emphasis on exclusive use of nonremunerated donors and centralizing blood collection organizations) are unintentionally adversely affecting blood collection in sub-Saharan Africa (34).

"In addition to economic incentives, policy-makers should consider nonpecuniary rewards (e.g., symbolic and with social recognition) and various appeals. Debates on ethical issues around giving rewards for donations (35) should be encouraged. But there should be little debate that the most relevant empirical evidence shows positive effects of offering economic rewards on donations."

Same sex marriage in Latin America

Things are changing all over the Americas regarding this no longer so repugnant transaction: How Latin Culture Got More Gay

"BRAZIL is potentially poised to become the third and largest country in Latin America to legalize same-sex marriage, following a judicial order on Tuesday. Argentina was the first, in 2010, after the government brushed aside objections from Cardinal Jorge Bergoglio of Buenos Aires, now the pope. The Uruguayan legislature followed suit last month. Mexico City has allowed such unions since 2010, and the Mexican state of Quintana Roo since 2011.
...
"These developments not only undermine stereotypes about machismo, but also the assumption that the prominence of Catholicism makes progressive change impossible. Same-sex marriage is legal in Belgium, Portugal and Spain, and Ireland recognizes civil unions. As the United States Supreme Court debates same-sex marriage, perhaps it should consider the precedent set by other nations of the Western Hemisphere."

Deceased donor waiting lists in Germany: scandal and aftermath

In an article entitled "Trust is Everything," Sue Pondrom reports in the American Journal of Transplantation (May 2013, vol 13 issue 5 pp1115-6) on the aftermath of a German transplant scandal.

"After a scandal regarding transplant corruption in Germany, the Deutsche Stiftung Organ transplantation (DSO), Germany's organ procurement organization, has announced that organ donations in the country were down nearly 13% by the end of last year.

"Public confidence in Germany's transplant system has suffered dramatically since newspapers throughout the country described cases of waitlist manipulation over the last 10 years at four liver transplant centers: University of Göttingen, University of Regensburg, Munich Klinikum rechts der Isar hospital and University Hospital Leipzig. At all four centers, doctors falsified liver patient medical records to indicate the patients were also undergoing dialysis. As a result, those patients were erroneously moved up the waiting list."

Post ATC post

Well, I'm back from the American Transplant Congress in Seattle, and it was quite nice to see multiple sessions on various aspects of kidney exchange, which has now graduated to the status of one of the standard ways of arranging kidney transplantation.

Here's the ATC's coverage of my Sunday talk: Keynote: Medical Community, Economist Collaboration Essential in Kidney Exchange

Alvin E. Roth, PhD: ‘Economics is about more than money and prices. It's also about organization, cooperation and coordination.'

If ever an endeavor existed that calls for careful, thoughtful collaboration, it is paired kidney exchange. Nobel laureate economist Alvin E. Roth, PhD, addressed the challenges in such exchanges and what economists can bring to this collaboration when he delivered Sunday's Keynote Lecture, "Kidney Exchange: An Economist's Perspective."

"Many things must happen to bring kidney transplant donors and recipients into the operating room," said Dr. Roth, the Craig and Susan McCaw Professor of Economics at Stanford University and the George Gund Professor Emeritus at Harvard University. "For some of those things, it has proven beneficial to look beyond the boundaries of the medical community to economists and market designers. Economics is about more than money and prices. It's also about organization, cooperation and coordination. 

Interdisciplinary collaboration is common in market design because market designers help experts in specific areas organize to achieve their goals. Dr. Roth said some remarkable transplant surgeons have collaborated with him and his colleagues in the ongoing effort to increase transplantation through exchange.

Even more collaboration will be required to coordinate among the multiple organizations involved in kidney exchange. A collaborative system that encompasses the largest pool of patients theoretically would produce the most transplants, but large organizations can be bureaucratic and inhibit innovation if not properly structured, he said. Some of the fastest-moving, entrepreneurial, innovative transplant organizations have been arranging the most transplants.

"Collaboration among kidney exchange programs is going to be important," Dr. Roth said. "However, we will have to put some careful thought in how to do it." 

In discussing logistics, he praised the non-directed, non-simultaneous donor chain as an innovation that has allowed the exchange of more kidney donations and has led to an increasing number of transplants. The chain begins with a non-directed donor, i.e. one who does not have an intended recipient and who donates to a patient in the kidney exchange pool of patient-donor pairs. That patient's donor continues the chain by donating to another patient in the pool, and so on, typically ending in a donation to a patient who has no donor.

"The ability to make non-simultaneous donations has allowed these chains to become quite long," Dr. Roth said. "That, in turn, has produced many more kidney transplants, which can include more of the most highly sensitized patients."

As more transplant centers have become adept at kidney exchange, there is a growing tendency for them to hold back their easy-to-match patients from the centralized kidney exchange pools to match these patients in their own centers. The consequence has been that hard-to-match patients are overly represented in kidney exchange pools.

"Easy-to-match patients in the mix are good for hard-to-match patients," Dr. Roth said. "We need to find ways to make it reasonable for the easy-to-match pairs to be in the large kidney exchange pools."

Finance also is an issue. Kidney exchange involves collaboration among hospitals, each of which may have different charges for nephrectomies, for example. One solution may involve developing a standard acquisition charge to make live kidney donation as uniform as it already is for deceased donor kidneys.

And expect kidney exchange design to remain in flux.

"The design of how kidney exchanges are organized is an ongoing process that has to change in reaction to changes in how transplant centers behave and what the patient pool looks like," Dr. Roth said. "We shouldn't think of it as something that is fixed in time but something that requires constant attention." 

5 Are Convicted in Kosovo Organ Trafficking

Here's the story from the NY Times: 5 Are Convicted in Kosovo Organ Trafficking

"Five people were convicted Monday in Pristina, the capital of Kosovo, in connection with an elaborate organ-trafficking network that lured poor people to the country to sell their kidneys and other organs to wealthy transplant recipients from Israel, the United States, Canada and Germany. Organs sold for as much as $130,000 each.
"The defendants, all Kosovars, were tried before a panel of two European Union judges and one Kosovar judge. A special prosecutor for the union, Jonathan Ratel, called the case a landmark because doctors had been convicted.
...
“The sole and driving motive for this exploitation of the poor and the indigent was the opportunity for obscene profit and human greed,” Mr. Ratel, the prosecutor, said Monday. “In every sense this was a cruel harvest of the poor.”
...
"According to the indictment in the case, traffickers in the network promised payments of up to $26,000 to poor people in Turkey, Moldova and Russia to persuade them to travel to Kosovo and donate an organ. They were asked to sign false documents saying they were donating to a relative for humanitarian reasons.

"Two dozen donors were taken in by the scheme; many were never given any compensation and were released without adequate medical care."
...
"Mr. Ratel said the Dervishis were aided by Dr. Yusuf Sonmez, whom he called a notorious international organ trafficker. Dr. Sonmez is a fugitive and may be in South Africa, Mr. Ratel said."

An economist goes to a surgery conference: American Transplant Congress, May 18-22

An unusual thing about giving a talk at a transplant conference is that it comes with a series of pre- (and perhaps post-) announcements...not that I'm feeling any pressure...

Don't Miss featured Keynote Speaker & Nobel laureate Alvin E. Roth, PhD, presenting

"Kidney Exchange: An Economist's Perspective" 
Sunday, May 19, 5:45 - 6:15 pm

With decades of experience and knowledge in experimental economics, game theory, and market design, Dr. Roth will provide insight into how he has applied economic theory to real-world problems at this year's ATC meeting.

Dr. Roth serves as the Craig and Susan McCaw Professor of Economics at Stanford University and the George Gund Professor of Economics and Business Administration Emeritus at Harvard University. He contributed to the National Bureau of Economic Research paper on kidney exchange, which was published in the Quarterly Journal of Economics.

Dr. Roth was awarded the Nobel Memorial Prize in Economic Sciences jointly with Lloyd Shapley for his work on the theory of stable allocations.

Here's an ATC press release:

Nobel Laureate to Describe How Economics Play Key Role in Kidney Exchange

Nobel laureate Alvin E. Roth, PhD, will discuss the economics of kidney exchange when he delivers the Keynote Lecture.

Nobel laureate Alvin E. Roth, PhD, has applied his economics expertise to strategies for organizing paired kidney donation exchange effectively, and he will share insights he has gained from this work when he presents the Keynote Lecture "Kidney Exchange: An Economist's Perspective" Sunday evening, May 19.

"This lecture will be an opportunity to offer an economist's perspective to a community of clinicians, surgeons and other health professionals, and explain what I see as some of the issues involved in implementing kidney exchange effectively," he said. "As an economist, I study how exchanges can be organized, and there is a great deal that has been, and can be, done to help organize kidney exchange."

The issues of organization emerge at different levels — within a transplant center, within a kidney exchange network, in collaboration among kidney exchange networks and in the development of national policy for kidney exchange. While much of the conversation focuses on what kinds of kidneys are suitable for the different patients needing transplantation, Dr. Roth said, attention also needs to be paid to how to make kidney exchange work well for transplant centers so that it can continue to grow.

Dr. Roth comes to the lecture with decades of contributions in game theory, market design and experimental economics, and in applying economic theory to solutions for real-world problems. He ventured into the real-world problem of kidney exchange when he and economist colleagues wrote a National Bureau of Economic Research paper "Kidney Exchange," which was ultimately published in the May 2, 2004, edition of the Quarterly Journal of Economics. They corresponded with transplant surgeon luminary Francis L. Delmonico, MD, and immunologist Susan L. Saidman, PhD, of Massachusetts General Hospital, Boston, and ultimately collaborated in forming the New England Program for Kidney Exchange (NEPKE) in 2005. Dr. Roth also worked with transplant surgeon E. Steve Woodle, MD, urologist Michael A. Rees, MD, and colleagues in developing the Paired Donation Consortium in Ohio and the Alliance for Paired Donation.

Currently, Dr. Roth is the Craig and Susan McCaw Professor of Economics at Stanford University and the George Gund Professor of Economics and Business Administration Emeritus at Harvard University. He was awarded the Nobel Memorial Prize in Economic Sciences jointly with Lloyd Shapley for his work on the theory of stable allocations and the practice of market design.

and here's the ATC pre-talk post this morning (now I better finish preparing the talk...)

Transplant surgeons and economists are joining forces to implement efficient, effective paired kidney donation exchange systems. Learn how economics plays a role in this endeavor when Nobel laureate Alvin E. Roth, PhD, speaks about "Kidney Exchange: An Economist's Perspective" during the Keynote Lecture at 5:45 pm today in Room 6E. He won the Nobel Memorial Prize in Economic Sciences jointly with Lloyd Shapley, PhD, in 2012 for his work on the theory of stable allocations and the practice of market design. 

"Organized kidney exchange clearinghouses arose out of collaborations between transplant professionals interested in improving patient care by expanding the number of transplants, and economists interested in market design. Transplant institutions have their different interests and ways of looking at patient care, and treating people with end-stage renal disease is a multi-billion dollar industry in the United States, so it's not surprising to find that sometimes complicated economic interests are also at play," said Dr. Roth, the Craig and Susan McCaw Professor of Economics at Stanford University and the George Gund Professor of Economics and Business Administration Emeritus at Harvard University. 

Exploring how those economic and medical institution interests can interact will help all parties involved determine how to move forward, Dr. Roth said. Kidney exchange will require innovations in how to arrange, coordinate and conduct surgeries, and in how to assemble and organize efficient clearinghouses. Therefore, paired kidney exchange is a natural area of collaboration between surgeons and economists. 

Issues of organization entail the various levels of kidney exchange, he noted. Within a single transplant center, the question is how to organize surgeries to obtain the most suitable transplants for the most patients. At the next level, there is the question of how different transplant centers can coordinate with one another in a kidney exchange network. And then there are questions about how different kidney exchange networks function and interact with each other. Thus questions about organizing kidney exchange nationally are often at least partly about economics. 

A recent challenge is that many transplant centers now have enough experience with kidney exchange to conduct their own exchanges internally among their patient-donor pairs. The unintended result, Dr. Roth said, is that kidney exchange pools now consist increasingly of highly sensitized patients. One response to an over-representation of highly sensitized patients is the development of long non-simultaneous, non-directed donor chains to match compatible kidneys for these patients. 

"We have to figure out ways to get more of the easy-to-match pairs into pools where they can be matched with harder-to-match pairs," he said. "Suppose you have many highly sensitized patients, and when you find a compatible kidney from an incompatible pair that would work for another pair, it's unlikely the receiving pair can donate a kidney back. That's why chains are particularly important for highly sensitized patients. Long non-directed donor chains are beneficial to the most highly sensitized patients. Transplant centers can exchange paired kidney donations on a national level and still perform the surgeries in their own centers." 

What can transplant surgeons, clinicians and allied health professionals do? Attend Dr. Roth's lecture, understand the benefits of kidney exchange and contribute to growing it. Transplant professionals and economists alike are still working out how to make kidney exchange work well for patients, donors and transplant centers. 

"Working those things out will make it easier for transplant centers to enroll their patients and donors," Dr. Roth said. "There are gains to achieve through collaboration among transplant professionals with different kinds of expertise. It is a great privilege as an economist to be able to contribute to this endeavor. It is good that transplant professionals interested in kidney exchange have been able to look outside of what is known just in the surgical community to bring in other kinds of help. It is good for us as economists that we are able to obtain these insights from surgical experts so that we can assist them."

An Alliance for Paired Donation reception: "Business Attire"

Art and Economics in Fresno

I received the following, unusual email:

I am writing to let you know about my exhibition "ImPOSSIBLE CONVERSATIONS?" at the Fresno Art Museum. 

It is roughly based on your research in matching theory.

Thank you for the inspiration,

Sonya Rapoport

ImPOSSIBLE CONVERSATIONS? is an interactive artwork that updates the Pattern and Design (P&D) art pieces that I created  from 1966 to 1968. I had painted iconic abstractions directly onto kitchy patterned linen from closeout sales. The results became my Funky P&D artwork.

Upon learning about the 2012 Nobel Prize in Economic Science for Marketing Design and Matching Theory, I was inspired to update the P&D work according to the research of its winners, Alvin Roth and Lloyd Shapley. 

ImPOSSIBLE CONVERSATIONS? pays tribute to Marketing as Andy Warhol's work pays tribute to Celebrity. The updated P&D work consists of ten stable images composed of a black and white, 8 x 10" glossy photograph of a 60's P&D painting placed on a New York Times Advertisement. I titled each of these ten stable art works with an unstable media headline, such as "Find Your Magic." The titles are "unstable" because I invite viewers to reassign the titles to a "stable" image of their choice. I track the results in a Matching Theory algorithm.

The work of Nobel laureates Roth and Shapley seeks to optimize how people, such as medical students and job applicants, and institutions, like residency programs and companies, find and select each other in order to create stable matches.

ImPOSSIBLE CONVERSATIONS? demonstrates both restricted and unrestricted mechanisms for matching. I organized data-gathering events in which groups of ten participants picked one "unstable" title and matched it with one "stable" composite image. I then removed this newly named work, leaving only nine titles for re-matching with the nine remaining composite images. This restricted mechanism of matching continued until all titles were assigned to a composite image. During the exhibition at the Fresno Art Museum, participants will engage in the unrestricted mechanism of matching any title to any composite image, previously selected or not.

In ImPOSSIBLE CONVERSATIONS? I try to merge art with economic science. By encouraging people to interact with my composite artworks, I created a simplistic model of the Marketing Design and Matching Theory to demonstrate the difference between the restricted and unrestricted selections.

Donate Life California solicits living kidney donors

Donate Life California Launches Living Donation California

"SACRAMENTO, Calif., May 14, 2013 – Living Donation California launched today as a first-of-its-kind, state-authorized information and referral service to inspire and inform people to be altruistic living kidney donors. Through its website, www.LivingDonationCalifornia.org, the free service provides information about living kidney donation and refers potentially eligible individuals for evaluation at a transplant center.

“There is a national shortage of kidneys available for transplant, and the need is especially acute in the State of California. By encouraging people to be altruistic kidney donors, Living Donation California gives hope to the thousands of transplant-eligible Californians who spend years on dialysis – years they could be spending more time with family, working and living healthy, active lives,” said Lisa Stocks, Board President of Donate Life California, administrators of the state’s organ and tissue donor registry who together with fifteen kidney transplant programs developed the Living Donation California initiative.

In California, kidney transplant candidates wait up to ten years, and for many patients twice as long as the national average, for a kidney transplant from a deceased donor. Circumstances allowing for organ recovery at the time of death are a rare (less than one percent) occurrence, so the state’s transplant community is focused on increasing living donation to help the large and growing number of Californians in need of kidney transplants.

The vast majority of living kidney donors are family or close friends of their recipients. A small but growing percentage are altruistic donors who offer the gift of a kidney without expectation of receiving anything in return. Federal law prohibits buying and selling organs for transplant, although in some cases living organ donors may be reimbursed for travel and other expenses incurred during the donation process. However, altruistic donors commonly feel greatly empowered by their choice to donate a kidney."

14th ACM Conference on Electronic Commerce June 16-20, The University of Pennsylvania

Here, from David Parkes is the call for participation in the EC conference at Penn in June. Note the deadlines of May 24 for hotels and May 28 for registration.  It looks like market design will be well represented, including two tutorials called just that by Utku Unver and Tayfun Sonmez.  I'll speak about developments in kidney exchange:

Kidney Exchange: where we’ve been and where we can go from here

Abstract: I’ll give an overview of the growth of kidney exchange and of the computational, economic, and behavioral issues that arise.  Kidney exchange has grown into an enterprise involving many hospitals and overlapping exchange networks, and in the process the set of strategic players has changed, and so has the patient pool. I’ll discuss how the market design has evolved to keep pace with these changes, and further challenges that remain, for the medical community, for economists, and for computer scientists.

Marginal Revolution: Manhattan meets Disney World

Tyler Cowen at MR writes today about this repugnant market, described in the NY Post: Rich Manhattan moms hire handicapped tour guides so kids can cut lines at Disney World

And Minnesota makes 12 (states that have legalized same sex marriage)

As more states legalize same sex marriage, its status as a repugnant transaction isn't yet history. Minnesota's move was hardly bipartisan: Minnesota Senate Clears Way for Same-Sex Marriage

"Gay couples will be permitted to wed in Minnesota starting in August, making it the 12th state to permit same-sex marriage and the first in the Midwest to take such a step outside of a court ruling.

"The State Senate, controlled by Democrats, voted 37 to 30 on Monday to allow same-sex marriages, after approval by the State House last week. Gov. Mark Dayton, also a Democrat, had urged lawmakers to pass the measure and said he would sign the bill on Tuesday afternoon.
...
"Nationally, advocates of same-sex marriage lauded Minnesota’s move, saying it would add momentum to similar efforts elsewhere, including in at least one other Midwestern state, Illinois, which is considering a provision legalizing same-sex marriage. Critics of the Minnesota measure, meanwhile, predicted that the vote on Monday would carry a lasting political price for the state’s Democrats in coming elections. They also said that barring a sweeping ruling by the United States Supreme Court establishing same-sex marriage as a right, other states were not likely to follow Minnesota’s lead in a sudden wave of legislative changes.

"In a way, Monday’s vote was a startling shift in the conversation in this state. For much of 2012, Minnesotans had been debating an amendment to the state Constitution that would have done the opposite — define marriage as between a man and a woman. While 30 states have adopted such provisions, Minnesotans in November rejected the amendment and sent majorities of Democrats to both chambers of the State Legislature, setting off an intense new push to legalize same-sex marriage.
...
"The issue had pitted this state’s most urban area, around the Twin Cities, against rural sections of the state where lawmakers said support was more uncertain. In both chambers, voting fell along largely partisan lines.

In the end, four Republicans in the State House and one in the State Senate voted to allow same-sex marriage, while two House Democrats and three Senate Democrats voted no."

Choices of low achieving students in NYC high school choice

The Institute for Education and Social Policy has a report out on NYC high school choices, and how these differ for high and low achieving students. (I blogged about news reports of this and related studies here.)

The study itself, by Lori Nathanson, Sean Corcoran and Christine Baker-Smith, all of NYU is here:
High School Choice in New York City: A Report on the School Choices and Placements of Low-Achieving Students

Here's the summary of the executive summary:


Key Findings
• Low-achieving students were matched to schools that were lower performing, on average, than
those of all other students.
• These differences in placements were:
- Driven by differences in students’ initial choices—low-achieving students’ first-choice
schools were less selective, lower-performing, and more disadvantaged;
- Not a consequence of low-achieving students being less likely to receive their first
choice—overall, lower-achieving and higher-achieving students were matched to their top
choices at the same rate.
• Both low- and higher-achieving students appear to prefer schools that are close to home. Thus,
differences in students’ choices likely reflect, at least in part, the fact that lower-achieving
students are highly concentrated in poor neighborhoods, where options may be more limited.

Looking back at the first year of New Orleans' One App school choice system

New Orleans families should get their choice list in by the deadline of May 24 (don't wait til the last minute).  In the meantime, the Times-Picayune recaps last year's experience: Ben Franklin Elementary, McMain top OneApp choices for 2013-14

"In their first year in the unified New Orleansschool enrollment system, the five Orleans Parish School Board direct-run schools punched above their weight. Going into the 2013-14 school year, Ben Franklin Elementary was the most popular choice for younger students and McMain was the most popular high school, according to new OneApp data provided to NOLA.com | The Times-Picayune. 

"OneApp, now in its second year, aims tostreamline the school enrollment process in New Orleans' decentralized, two-district system. Families fill out one application and a computer algorithm matches students to open seats, by random lottery plus a few priority factors such as having a sibling in a school or, for the elementary years, geographic catchment area.

"All the schools in the city participate except for OPSB's popular charters and a handful of state-authorized charters that can take students from outside Orleans Parish. TheRecovery School District started the program and continues to lead it."
