The Amsterdam court rules on school choice

Hessel Oosterbeek sends the following update on the school choice court case seeking to allow the exchange of school places that were allocated by a deferred acceptance algorithm with multiple tie breaking.  He writes: 

"Attached is a link to the decision of the judge in Amsterdam. Important considerations for the judge are that: i) trading would harm students who have a higher position on the waiting lists, and ii) allowing trade this year makes the system unusable in the future. The judge also writes that the rules were clear.

Overall it reads that the judge is well informed."

Google Translate allows you to make reasonable sense of the judge's decision in English...

Here is a blog post, also in Dutch, but Google Translate does a good enough job so that you can see that this is a pretty detailed discussion of various algorithms, strategy-proofness, the judge's decision, etc. It seems that the public discussion is going on at a pretty high level:

Video conversation about Who Gets What on Yahoo! Finance


Below is a link to a Yahoo! Finance video interview (about 5 minutes), made when I was in NYC for the launch of  Who Gets What and Why the first week in June. Unlike most of the interviews I've done, this one has video footage added, so instead of always looking at me and the interviewer, there are scenes of things that we're talking about--the stock exchange, an Amazon warehouse, etc..

Scott Kominers on market design (and a conference in August)





Prof. Scott Duke Kominers: ‘There are many new areas of market design worth exploring’


Kominers 1
Prof. Scott Duke Kominers is a Junior Fellow at the Harvard Society of Fellows, a Research Scientist at the Harvard Program for Evolutionary Dynamics, and an Associate of the Harvard Center for Research on Computation and Society. He also will be a General Co-Chair at AMMA 2015, The Third Conference on Auctions, Market Mechanisms and Their Applications. We talked with him about the upcoming conference and about the most interesting potential areas in market design and the challenges this field will face in the near future.

AMMA 2015 will be held August 8-9, 2015 in Chicago. What will the main focus of the conference be?

AMMA focuses on the theory and practice of market design, at the intersection of economics, computer science, operations research, and applied math.

What are, in your opinion, interesting potential areas researchers in the field of market design should take into account?

Prof. Scott Duke Kominers, General Co-Chair at AMMA 2015

Market design has already proven useful in addressing real-life problems in settings like school choice, entry-level labor markets, kidney exchange, and auction design. Financial market design has flourished recently, as has the design of intellectual property markets. Personally, I am especially excited about “generalized matching,” which blends together ideas from matching and auction theory to show how markets with complex contract structure can be cleared using relatively simple mechanisms. I think there’s a lot of potential for generalized matching mechanisms to be useful in new real-world applications. In addition, there are many new areas of market design worth exploring: market designers are starting to think about the structure of healthcare marketplaces and adoption services. And of course, online platforms are everywhere. Furthermore, a popular press book on market design has just been published: http://www.hmhbooks.com/whogetswhat/index.html.

What challenges do you expect market design will face in the near future?

I think one of the greatest challenges going forward is about translation: we need to find good ways of teaching what we know about marketplace design to policymakers, entrepreneurs, and other practitioners. In some cases, there is work to be done in understanding how to simplify our mechanisms in ways that would make them more accessible to their users. Meanwhile, on the research side, market design has traditionally mixed powerful theory with empirical analysis, experiments, and computational methods. As we build more and more technical facility with our existing tools, and as we add new approaches to our toolkits, it is increasingly challenging – but also increasingly important – to make sure that we let real-world structure guide our methodological choices in applied work.

Changes in repugnance over time

Bloomberg news has some animated graphics showing the change over time in repugnance--as measured by laws at the state level--for six issues that were or are controversial in America: interracial marriage, prohibition, women’s suffrage, abortion, same-sex marriage, and recreational marijuana.

This Is How Fast America Changes Its Mind, By Alex Tribou and Keith Collins

All of those have now had Federal rulings, except for recreational marijuana, which as of this writing has been legalized only in Colorado, Washington, Oregon and Alaska.  Stay tuned...

Financial support for organ donors in New Zealand? A new bill proposed...

New Zealand's parliament will debate a bill to increase the financial support offered to organ donors.

Member’s Bill will boost financial support for organ donors

Member’s Bill will boost financial support for organ donors

Chris Bishop, National List MP based in the Hutt Valley, is delighted the Financial Assistance For Live Organ Donors Bill, a Member’s Bill in his name, has been drawn from the ballot and will be debated by Parliament.
The purpose of the Bill is to increase the financial assistance provided to people who, for altruistic reasons, donate kidney or liver tissue for transplantation purposes.
The Bill will increase the support for donors from the equivalent of the sickness benefit to the equivalent of 80 per cent of the donor’s pre-operation earnings – the same formula applied to income support for ACC recipients. The Bill also provides for the payment of childcare assistance for those who require it during their convalescence.
“I was inspired to pick up this Member’s Bill, which was originally put forward by Hon Michael Woodhouse, after talking to Sharon van der Gulik at one of my first meetings as a candidate in the election last year,” Mr Bishop says. “She had been living with renal failure for more than two years and needed 15 hours of dialysis a week – before her son donated one of his kidneys to her.
“At the public meeting, Mrs van der Gulik spoke of the financial hardship that her son faced in the six weeks he spent recovering from the procedure. She argued he deserved more. I agree.
“If this Bill passes into law, greater support will be available to people like Mrs van der Gulik’s son.
“Organ donation rates in New Zealand are improving, but are still too low. It’s important they increase - live kidney donation is the least expensive form of treatment for end-stage renal failure, and significantly improves life expectancy.
“This Bill is a small but important and helpful step to increasing the number of people who donate organs.
“Wider work to increase the number of donors is being led by the Minister of Health. Budget 2014 allocated $4 million over four years to set up a National Renal Transplant Service to increase the number of live kidney donor transplantations. The funding covers donor liaison co-ordinators and continuation of the New Zealand Kidney Exchange programme. Last year's funding increase builds on the $4 million invested in Budget 2012 to raise awareness and encourage more people to donate organs,” says Mr Bishop.

Elias, Lacetera and Macis on the repugnance of paying for organs or prostitution: a survey experiment


Markets and Morals: An Experimental Survey Study
Julio J. Elias , Nicola Lacetera , Mario Macis

PLOS One. Published: June 1, 2015DOI: 10.1371/journal.pone.0127069

Abstract: Most societies prohibit some market transactions based on moral concerns, even when the exchanges would benefit the parties involved and would not create negative externalities. A prominent example is given by payments for human organs for transplantation, banned virtually everywhere despite long waiting lists and many deaths of patients who cannot find a donor. Recent research, however, has shown that individuals significantly increase their stated support for a regulated market for human organs when provided with information about the organ shortage and the potential beneficial effects a price mechanism. In this study we focused on payments for human organs and on another “repugnant” transaction, indoor prostitution, to address two questions: (A) Does providing general information on the welfare properties of prices and markets modify attitudes toward repugnant trades? (B) Does additional knowledge on the benefits of a price mechanism in a specific context affect attitudes toward price-based transactions in another context? By answering these questions, we can assess whether eliciting a market-oriented approach may lead to a relaxation of moral opposition to markets, and whether there is a cross-effect of information, in particular for morally controversial activities that, although different, share a reference to the “commercialization” of the human body. Relying on an online survey experiment with 5,324 U.S. residents, we found no effect of general information about market efficiency, consistent with morally controversial markets being accepted only when they are seen as a solution to a specific problem. We also found some cross-effects of information about a transaction on the acceptance of the other; however, the responses were mediated by the gender and (to a lesser extent) religiosity of the respondent—in particular, women exposed to information about legalizing prostitution reduced their stated support for regulated organ payments. We relate these findings to prior research and discuss implications for public policy.

Ransom as a repugnant transaction--the U.S. relaxes its position

The U.S. is revisiting laws and policies against paying ransom to pirates, terrorists and other hostage takers.

In New Hostage Policy, U.S. Will Not Prosecute Families for Paying Ransom

"After a six-month review that included discussions with families of people held overseas, the White House said the government will continue its longstanding policy of not making concessions to hostage-takers.

But it will no longer threaten families who decide to pay ransoms. The government may communicate with hostage-takers and intermediaries, and it may help families who are trying to pay ransom, the White House said."

Obama Announces New Hostage Response, but No U.S. Ransoms

"The president reasserted the main plank of U.S. policy that, unlike some allies, the government would not make concessions or pay ransom to hostage takers, saying this would enrich the militants and encourage further abductions.

However, he set out a more cooperative policy in which the government would work with the families, and said a special presidential envoy would be appointed to coordinate the efforts of law enforcement and diplomats.

Government officials would now be allowed to communicate and negotiate with hostage takers.

The new approach was drawn up over six months after complaints by families that their initiatives to free relatives had been discouraged and sometimes blocked by officials who threatened legal action if they raised a ransom privately.

He said - as did a separate statement from the Justice Department - that such threats should never happen again, and that no American had been prosecuted for paying a ransom.

The new approach, set out in a presidential directive, allowed "communication with hostage takers by our government, the families of hostages or third parties who help these families," Obama said."

Kidnapped Missionary Was Freed as U.S. Tested Hostage Policy Shift - Family

"The family of a U.S missionary kidnapped in Nigeria earlier this year said on Thursday it paid a ransom to secure her release in March while receiving around-the-clock guidance from federal agents under a newly changed hostage-response policy."

An ancient repugnance crumbles: Same sex marriage is a right, in all 50 of the United States

Here's the NY Times headline: Same-Sex Marriage Is a Right, Supreme Court Rules, 5-4

"Justice Anthony M. Kennedy wrote the majority opinion in the 5 to 4 decision. He was joined by the court’s four more liberal justices."

We're all a little more equal today.

But the close vote means that understanding repugnant transactions--transactions that some people would like to engage in, and others wish to prevent--is important.

School choice in Amsterdam goes to court over tie-breaking

Hessel Oosterbeek sends me this article in Dutch about the very current controversy playing out in Amsterdam over this year's school choice results:

Het beest in de Amsterdamse ouder is los,
which Google Translate renders as
The beast in Amsterdam's parent is loose

Some background to the current controversy can be found in a paper by Oosterbeek and his coauthors which was influential in the Amsterdam school choice design (which used student-proposing deferred acceptance with multiple tie-breaking):

"The performance of school assignment mechanisms in practice," by Monique de Haan, Pieter A. Gautier, Hessel Oosterbeek, and Bas van der Klaauw.

Abstract: "Theory points to a potential trade-off between two main school assignment mechanisms; Boston and Deferred Acceptance (DA). While DA is strategyproof and gives a stable matching, Boston might outperform DA in terms of ex-ante efficiency. We quantify the (dis)advantages of the mechanisms by using information about actual choices under Boston complemented with survey data eliciting students’ school preferences. We find that under Boston around 8% of the students apply to another school than their most-preferred school. We compare allocations resulting from Boston with DA with single tie-breaking (one central lottery; DA-STB) and multiple tie-breaking (separate lottery per school; DA-MTB). DA-STB places more students in their top-n schools, for any n, than Boston and results in higher average welfare. We find a trade-off between DA-STB and DA-MTB. DA-STB places more students in their single most-preferred school than DA-MTB, but fewer in their top-n, for n ≥ 2. Finally, students from disadvantaged backgrounds benefit most from a switch from Boston to any of the DA mechanisms"

The city of Amsterdam adopted multiple tie-breaking, with the consequence that some post-assignment trades now seem possible between students.  And this is where the beast in Amsterdam's parents (some of whom are lawyers) has been loosed. Here's Google Translate again, on the news story:

"Moreover, there is a side effect that parents can not stomach: a class can sit next to each other two children who are both disappointed in the school they were assigned, whereas if they would swap, both overjoyed to be made ​​with a spot on their favorite school. A child who is placed in a school where he really did not want it (tenth place on his preference list), through an exchange would nevertheless may still end up at No. 1. And yet you can not. There is, every year it again what in Amsterdam that the beast in the parent disconnect when it comes to the choice of school of the child.
...
"A father of a girl who wants to be very happy in music and dance, with a spot on the Geert Groot School, turned to Sprenkeling for an exchange. To facilitate this exchange, harnessed the lawyer with 32 other parents a lawsuit against the dome of high schools Osvo. The aim is to consider the new placement system this year as a test. Only next year should really not be exchanged. "

I understand from Hessel that a judge is expected to rule soon on whether families may exchange school places...
