Description

Markets are an ancient institution for matching the supply for a good or service with its demand. Physical markets were typically slow to evolve, with simple institutions governing trade, and trading partners generally facing a daunting challenge in finding the “right” partner. The information technology revolution, however, has generated a sea change in how markets function: now, markets are typically complex platforms, with a range of mechanisms involved in facilitating matches among participants. Recent trends point to an unprecedented level of control over the design, implementation, and operation of markets: more than ever before, we are able to engineer the platforms governing transactions among market participants. As a consequence, market operators or platforms can control a host of variables such as pricing, liquidity, visibility, information revelation, terms of trade, and transaction fees. Given these variables, market participants often face complex problems when optimizing their own decisions. In the supply side such decisions may include the assortment of products to offer and their price structure, while in the demand side they may include how much to bid for different goods and what feedback to offer about past purchasing experiences. The decisions made by the platform and the market participants interact, sometimes in intricate and subtle ways, to determine market outcomes.

In this workshop we seek work that improves our understanding of these markets, both from the perspective of the market operator and the market participants. With respect to the former we are particularly interested in work that derives useful insights on how to design these markets, taking into account their operational details and engineering and technological constraints. With respect to the market participants, we seek work that introduces novel approaches to optimize their decisions and improves our understanding of their interactions within the market. We look for a mix of approaches including modeling, theory, and empirics, using a wide range of tools drawn from operations management, game theory, auctions and mechanism design, optimization, stochastic modeling, revenue management, econometrics, or statistics.

The list of markets to be studied includes but it is not restricted to:

• Online marketplaces, such as eBay, Etsy, etc.
• Internet advertising, including sponsored search and display ad exchanges
• Sharing economy markets, such as Uber/Lyft, AirBnb, etc.
• Online labor markets, such as Amazon mTurk, Upwork, Thumbtack, etc.
• Procurement markets, such as technology-enabled government procurement
• Health care exchanges
• Financial exchanges

The Retail Market for Illicit Drugs

Outlawing a market is often the first step in the design of the illegal black market that results. Here's a paper from the most recent AER on the market for crack cocaine:

A Structural Model of the Retail Market for Illicit Drugs
By Manolis Galenianos and Alessandro Gavazza

Abstract: We estimate a model of illicit drugs markets using data on purchases of  crack  cocaine.  Buyers  are  searching  for  high-quality  drugs,  but  they determine drugs’ quality (i.e., their purity) only after consuming  them.  Hence,  sellers  can  rip  off  first-time  buyers  or  can  offer  higher-quality drugs to induce buyers to purchase from them again. In  equilibrium,  a  distribution  of  qualities  persists.  The  estimated  model  implies  that  if  drugs  were  legalized,  in  which  case  purity  could be regulated and hence observable, the average purity of drugs would  increase  by  approximately  20  percent  and  the  dispersion  would decrease by approximately 80 percent. Moreover, increasing penalties may raise the purity and affordability of the drugs traded by increasing sellers’ relative profitability of targeting loyal buyers versus first-time buyers.

Who Gets What and Why in Spanish for Latin America

Here's the Spanish translation of my book Who Gets What and Why, for Latin America, published by Oceana.

Lo que sea de cada quien. La economía de las relaciones y el diseño de mercado

I gather from Manu Vespa that "Lo Que Sea De Cada Quien" is an idiom common in some parts of Latin America which means something like "To Each His Own." (More literally it seems to be "Whatever could be for each person..."

Google translate renders the title as "Whatever it is for each one. The economy of relationships and market design"

The Spanish translation for Spain was a much more literal "Who gets what and why":

Surrogacy in China: available but illegal

The Global Times has this story:
Surrogacy to ‘remain illegal’ By Liu Caiyu  

"China will not legalize surrogacy and will crack down on the crime, China's top health authority said Wednesday, after the People's Daily published an article hinting at support for the practice for older mothers.

Surrogacy is a complex problem involving law and ethics, and most nations and regions in the world ban any form of surrogacy and punish participating institutes and personnel, said Mao Qunan, a spokesperson with China's National Health and Family Planning Commission (NHFPC), said Wednesday during a press conference in Beijing.

"The commission and the government will continue to crack down on surrogacy and ensure the public can get safe and effective assisted reproductive technology," Mao said.

Since China eased its one-child policy in 2014, allowing couples to have a second child if either parent is an only child, and further loosened it to allow all couples to have two children in January 2016, more older mothers are trying to conceive, but are finding it difficult, a People's Daily article on Friday said.

The article quoted a doctor as saying that nearly 90 percent of women cannot conceive naturally after the age of 45. The average age for a final pregnancy is around the age of 40, although the number of older women giving birth has seen a continuous increase.

Among the 90 million families in China eligible to have a second child, 60 percent of the women are above 35 years old and 50 percent are over  40, data released by the NHFPC in January 2016 shows. In 1996, only 0.4 percent of women above 45 gave birth, rising to 4 percent in 2005 and 10 percent in 2015, it said.

Although China has a huge demand for surrogacy services, from both an ethical and legal standpoint, it is not feasible to legalize it now, Xia Yinlan, a professor at the China University of Political Science and Law,  told the Global Times.

"Legalizing surrogacy could worsen the problem of trafficked women, which is not humane and would increase discrimination against women," said Xia."

Incentives in Computer Science--Tim Roughgarden

There was a time when only economists worried about incentives, but as this great looking computer science course by Tim Roughgarden shows, that time is long past...

CS 269I: Incentives in Computer Science

Instructor:

• Tim Roughgarden (Office hours (note new time): Mondays 12:15-1:15 PM, Gates 474. Email: tim@cs.stanford.edu.)

Prerequisites: Mathematical maturity at the level of undergraduate algorithms (CS161). Programming maturity at the level of 106B/X.
Course Description: Many 21st-century computer science applications require the design of software or systems that interact with multiple self-interested participants. This course will provide students with the vocabulary and modeling tools to reason about such design problems. Emphasis will be on understanding basic economic and game theoretic concepts that are relevant across many application domains, and on case studies that demonstrate how to apply these concepts to real-world design problems. Topics include auction and contest design, equilibrium analysis, cryptocurrencies, design of networks and network protocols, matching markets, reputation systems, and social choice. Possible case studies include BGP routing, Bitcoin, eBay's reputation system, Facebook's advertising mechanism, Mechanical Turk, and dynamic pricing in Uber/Lyft.

Donor sibling registry: matching donor-conceived sibs

The Donor sibling registry is a matching service to help identify half siblings of  "donor conceived people," i.e. people who were conceived from donor sperm or eggs, and who may know only an anonymized donor number.  If your numbers match, you might want to arrange a meeting...

Who can be a common law couple?

Being a couple is about a lot of things, including survivor rights and medical visitation and decision-making rights...

Inseparable Israeli Sisters Fighting to Be Recognized as a Common Law Couple
"A day in court with two nonagenarian sisters, refugees from the Holocaust and constant companions, who seek the unprecedented status so that the one who lives longer can inherit the other's old-age allowance."

"The claimants, it turned out, are asking the National Insurance Institute to recognize each of them as being eligible to receive a next-of-kin allowance upon the other’s death. Effectively, they want the NII to grant them common-law status recognition.
A disturbing thought ran through the judge’s head. “Are you telling me that …” she said to attorney Igra who, guessing her thought, dismissed it with an “Absolutely not,” and placed before the judge a court ruling stating that sexual relations are not a condition for common-law recognition.
Relieved, the judge went on to sum up the lives of the two sisters in a few sentences, as she began reading her judgment. The claimants have lived in the same unit of a protected housing project since 2007. The claimants never married, are single and have no children. The claimants have a joint back account, and their old-age allowances have always been deposited in that account. The claimants manage their income and their expenses from the same bank account. The claimants purchased adjoining burial plots. The claimants’ only journeys abroad took place between 1995 and 1998, and always together, according to the Interior Ministry’s border inspection records.
...
"The Labor Court, though acknowledging the innovation and feasibility of the claim, did not accept it"

This request was not accepted by the Israeli court, but it is food for thought.

Reducing disincentives to living organ donation in New York State

Josh Morrison of Waitlist Zero is pictured in this encouraging story:

Albany considers bill to pay live organ-donors' costs
Supporters want to remove economic barriers that they say keep many potential donors from coming forward

"A new bill could make New York the first state in the country to directly compensate living organ donors—who typically donate a kidney or a portion of their liver to a transplant patient—for lost wages, child care and other expenses.

The Living Donor Support Act, introduced by Democratic Assemblyman Richard Gottfried of Manhattan and Republican Sen. Kemp Hannon of Long Island, chair of the Senate Health Committee, has broad support from lawmakers. It already unanimously passed Hannon’s committee, and it has 18 Senate co-sponsors and 27 Assembly co-sponsors.

In addition to helping donors with expenses, the bill seeks to increase education about the option of living transplants for patients, who are disproportionately poor and members of minority groups.

“Our goal is to make transplants easy to ask for and easy to give,” said Josh Morrison, executive director and co-founder of Waitlist Zero, a Brooklyn-based nonprofit that championed the bill. Morrison donated one of his own kidneys as a good Samaritan five years ago at the age of 26.

For dialysis patients in particular, getting a kidney transplant from a living donor could save money and improve their quality of life, but patients often aren't informed of that option, Morrison said."

Fifty shades of stigma: repugnance for legal but kinky sex

As a wider variety of sexual behavior becomes free of legal restrictions, some are still misunderstood or regarded as repugnant by much of the population, including medical professionals, even as they are featured (gently) in popular books and movies like “Fifty Shades of Gray.”

The Journal of Sexual Medicine explores the extent to which practitioners of kinky sex may feel that they cannot be frank with their physicians:

"Fifty Shades of Stigma: Exploring the Health Care Experiences of Kink-Oriented Patients"
Jessica F. Waldura, MD, Ishika Arora, BS, Anna M. Randall, DHS, John Paul Farala, MD, Richard A. Sprott, PhD

Abstract: "The term kink describes sexual behaviors and identities encompassing bondage, discipline, domination and submission, and sadism and masochism (collectively known as BDSM) and sexual fetishism. Individuals who engage in kink could be at risk for health complications because of their sexual behaviors, and they could be vulnerable to stigma in the health care setting. However, although previous research has addressed experiences in mental health care, very little research has detailed the medical care experiences of kink-oriented patients."

Results: "...The study found that kink-oriented patients have genuine health care needs relating to their kink behaviors and social context. Most patients would prefer to be out to their health care providers so they can receive individualized care. However, fewer than half were out to their current provider, with anticipated stigma being the most common reason for avoiding disclosure. Patients are often concerned that clinicians will confuse their behaviors with intimate partner violence and they emphasized the consensual nature of their kink interactions."

Hardy Hendren and the resident match

The journal Surgery has published (early online) an account by Hardy Hendren, recounting the drama at the origin of the resident match:
The 1951 Harvard student uprising against the intern match
Don K. Nakayama, MD, MBAa, , , W. Hardy Hendren III, MD, FRCSb
a Departments of Surgery, Florida International University, Sacred Heart Medical Group, Pensacola, FL
b Harvard Medical School, Massachusetts General Hospital, and Children's Hospital Boston, Boston, MA
Available online 18 January 2017
[Update: the published version appears in Volume 161, Issue 6, June 2017, Pages 1728-1734]

Here's the first paragraph:
"In the fall of 1951, a group of Harvard medical students led by W. Hardy Hendren, III organized a national movement against the newly instituted match that would assign graduating seniors to hospital internship programs. Before then, hospitals with intern positions to fill rushed to secure commitments from students, who in turn accepted the first decent offer that came their way. Knowing that students could not risk waiting for a better offer, hospitals pushed them into making early commitments. When some students began getting offers in their junior and sophomore years, medical schools, professional groups, and hospitals organized the National Inter-association Committee on Internships to deal with the issue. The intern match was thus organized and scheduled to take place in 1952. When the plan was announced in mid-October 1951, Hendren recognized that the proposed algorithm placed students at a disadvantage if they did not get their first choice of hospitals. Facing resistance at every step from the National Inter-association Committee on Internships and putting his standing at Harvard Medical School at risk, Hendren led a nationwide movement of medical students to change the procedure to one that favored students' choices. Their success [less than] 1 month later established in the inaugural match the fundamental ethic of today's National Resident Matching Program to favor students' preferences at every step of the process."

In my book Who Gets What and Why, I wrote about Hendren and these events in part as follows p138):
"One student who noticed this flaw in the proposed design was Hardy Hendren. He was preparing to graduate from Harvard Medical School in 1952, just as the clearinghouse was getting started. When he told me about it years later over lunch in Cambridge MA, he had already retired (in 1998) from Boston Children’s Hospital, where he had been chief of surgery. (His colleagues had given him the nickname “Hardly Human,” for the long, complicated surgeries he was able to conduct.) Hardy entered the Navy during WWII, in 1943 when he was seventeen, and trained as a pilot before returning to college and medical school. As you can imagine, with that background, as he prepared to seek his first job as a doctor, he wasn’t shy about expressing his concerns that the clearinghouse was unsafe for students.
"Hardy also wasn’t one to wait around for bureaucrats. And so, with a group of fellow students, he formed the National Student Internship Matching Committee, which organized opposition to the proposed algorithm. The Committee recommended that it be replaced with a different way of processing the preference lists to determine a match: it became known as the Boston Pool Plan. This was, in fact, the algorithm that was finally implemented when the clearinghouse was used to match students and positions in 1952."

After some discussion of stability, and the fact that the Boston Pool Plan is equivalent to the hospital proposing deferred acceptance algorithm, I wrote (p141):
"Back in 1952, economists hadn’t yet figured out any of this, which makes Hardy Hendren’s insight and his committee’s grassroots efforts all the more impressive."

Ken Arrow (1921-2017)

How will we do Economics without Ken Arrow?

After living to a vigorous 95, he passed away today after a mercifully short illness.  He was in the hospital for about two weeks, then went home. He had ups and downs, but a week and a half ago I found him dressed and at his computer.

 Even when he was feeling poorly, he was always the smartest person in the room.

Update, April 29:
The Lancet remembers Ken Arrow. Their obituary is gated, but here are two sentence that I contributed...

 "When asked if Arrow is indeed up there with there with greats, the Stanford University Professor of Economics Alvin Roth, himself a Nobel Laureate, answers with a corrective twist. “The greats are up there with him”, he replies. “He was arguably the most important economist of the 20th century.”

" “He was always the smartest person in the room”, says Roth, “but he wore it very lightly”

Travel bans and rank order lists for the resident match

Residency programs have to submit their rank order lists of applicants by Feb 22. Should they try to match with doctors from countries subject to a possible renewed US travel ban?

Travel Ban Confusion Complicates Match Day Decisions

"UPDATE:  The Trump administration announced February 16 that it would discontinue its legal push in appeals court to reinstate their travel ban, but would instead issue a new, revised immigration order next week. No other details were given.

As medical school students look ahead to Match Day on Friday, March 17, some international students have additional anxiety in light of the uncertainty surrounding President Trump's executive order banning travel for people in seven Muslim-majority countries.

Residency programs also have to decide whether they will hold spots for students from the targeted countries who may not be allowed to come to the United States if legal rulings change.

First comes decision day February 22, when preferences must be ranked by both programs and students.

"Some applicants are concerned that the program directors won't rank them and there's concern from programs on whether the students can begin training on time," Mona Signer, president and CEO of the National Resident Matching Program (NRMP), told Medscape Medical News.

Trump's executive order, issued on January 27, aims to prevent citizens of seven majority-Muslim countries — Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen — from entering the United States for 90 days. It suspended entry of all refugees for 120 days and barred refugees from Syria indefinitely. A federal judge has since imposed an emergency stay, halting the key parts of the executive order.

The administration's next step is unclear, but news sources have reported that Trump may take the fight to the Supreme Court or issue a revised order.

According to the Association of American Medical Colleges (AAMC), 260 medical students have applied to US residency programs from the seven countries the ban covers.

Questions include whether the ban will be reinstated, and, if it is reinstated, whether medical students would be exempted. Some worry the ban could spread to other countries. Last year, 3769 non-US citizens who studied medicine abroad matched into a US residency program, according to the American College of Physicians."

Offensive trademarks

Can repugnant speech also be intellectual property? The Supreme Court has a case that touches on this. The NY Times has this recent story: Justices Appear Willing to Protect Offensive Trademarks

"The Supreme Court on Wednesday appeared deeply skeptical about the constitutionality of a federal law that denies protection to disparaging trademarks. Almost every member of the court indicated that the law was hard to reconcile with the First Amendment.

The court’s decision in the case, concerning an Asian-American dance-rock band called the Slants, will probably also effectively resolve a separate one in favor of the Washington Redskins football team.

The law denies federal trademark protection to messages that may disparage people, living or dead, along with “institutions, beliefs or national symbols.”

Malcolm L. Stewart, a deputy solicitor general, said the trademark law does not bar any speech, as the Slants remain free to continue to use their name. The law “places a reasonable limit on access to a government program rather than a restriction on speech,” he said, and so “does not violate the First Amendment.”

Continue reading the main story

But Justice Elena Kagan said that even government programs may not discriminate based on speakers’ viewpoints.

“The point is that I can say good things about something, but I can’t say bad things about something,” she said of the law. “And I would have thought that that was a fairly classic case of viewpoint discrimination.” Viewpoint discrimination by the government, the Supreme Court has said, is presumptively unconstitutional.

Justice Anthony M. Kennedy said the law interfered with free expression.

“We have a culture in which we have T-shirts and logos and rock bands and so forth that are expressing a point of view,” he said. “They are using the market to express views.”

Memorial conference for Professor Reinhard Selten, April 28

Memorial conference for Professor Reinhard Selten
Friday, April 28th 2017, Bonn,

Reinhard Selten was a pioneer of the analysis of strategic interaction of both fully rational players (game theory) and boundedly rational humans (experimental economics). From 1984 until his death in 2016, he was associated with the University of Bonn, where he established one of the first experimental laboratories in economics. In 1994, Selten was awarded the Nobel Memorial Prize in Economic Sciences, together with John Harsanyi and John Nash, for their pioneering analysis of equilibria in the theory of non-cooperative games.

To honor his outstanding contributions to Economics, the University of Bonn and the University of Cologne are hosting a memorial conference for Reinhard Selten. The aim is to bring together renowned speakers presenting work connected to or inspired by Selten’s research. The conference will take place on Friday, April 28th 2017 at the Günnewig Hotel Bristol in Bonn, Germany. To help us with our planning, please register as soon as possible if you plan to attend!

Vatican statement on organ transplantation

When I posted recently about the Vatican conference on organ trafficking and transplant tourism I focused on the participation of China, and the reaction it drew.

Now I've had a closer second look at the conference statement  (whose title is Statement of the Pontifical Academy of Sciences Summit on Organ Trafficking and Transplant Tourism). (UPDATED LINK HERE: https://www.pas.va/en/events/2017/organ_trafficking/final_statement.html )

It's a very tough statement, which casts quite a broad net when talking about "crimes against humanity." Here's the opening paragraph:

"In accordance with the Resolutions of the United Nations and the World Health Assembly, the 2015 Vatican Summit of Mayors from the major cities of the world, the 2014 Joint Declaration of faith leaders against modern slavery, and the Magisterium of Pope Francis, who in June 2016, at the Judges’ Summit on Human Trafficking and Organized Crime, stated that organ trafficking and human trafficking for the purpose of organ removal are “true crimes against humanity [that] need to be recognized as such by all religious, political and social leaders, and by national and international legislation,” we, the undersigned participants of the Pontifical Academy of Sciences Summit on Organ Trafficking, resolve to combat these crimes against humanity through comprehensive efforts that involve all stakeholders around the world."

Here's the paragraph defining what those crimes against humanity are, which to my eye seems to conflate three very different things. It is number 1 in their list of recommendations.

"That all nations and all cultures recognize human trafficking for the purpose of organ removal and organ trafficking, which include the use of organs from executed prisoners and payments to donors or the next of kin of deceased donors, as crimes that should be condemned worldwide and legally prosecuted at the national and international level."

That is, if I read the full statement correctly (you should read it yourself), they are proposing that 

1. taking organs from executed prisoners, 
2. making payments to living donors, and 
3. making payments to next of kin of deceased donors 

should all be considered crimes against humanity.  

Incidentally, the phrase "crimes against humanity"  is one that I hear most often in the context of genocide, although I recognize that it is also used for other horrific crimes that target populations.

I am not encouraged that this will lead to a sensible discussion about either incentives for donation or (even) removing financial disincentives.

Doctor assisted suicide in Colorado: repugnance outlives legalization

You can figure out much of this story from the headline (but there's more): Colorado’s aid-in-dying law in disarray as big Catholic health systems opt out

...
"A third big health system in the state, HealthONE, has decided it won’t dispense life-terminating medications or allow patients to take them on the premises of its eight hospitals. But HealthONE, which is not faith-based, won’t impose similar restrictions on its doctors. A spokeswoman declined to provide details.

"The state’s law, which became effective last month, requires that such patients be 18 or older, have six months or less to live, be mentally competent, and ask for aid in dying twice over 15 days, in addition to a separate written request.

“Everyone is in a mad scramble figuring out what they’re doing to do and how they’re going to do it,” said Jennifer Moore Ballentine, president of The Iris Project, a Colorado consulting firm that is running a series of seminars on the new law over the next few weeks.

Colorado’s aid-in-dying law contains “conscience” provisions allowing physicians, nurses, and pharmacists to “opt out” of participating. Health systems can also bar the practice on their premises. Other states where aid in dying has become legal — Oregon, Washington, California, Vermont, and Montana — have similar provisions, and Catholic health care systems in those states have taken advantage of it.

But the Colorado law specifically states that health systems can’t prohibit doctors who work for them from discussing end-of-life options with patients or writing prescriptions to be taken off-site. This provision was crafted to prevent health systems from erecting barriers to access; only Vermont has a similar rule, but it doesn’t have a heavy concentration of Catholic hospitals.

Advocates for Colorado’s law say the two big Catholic health systems may be testing that provision."

The politics of assisted suicide / death with dignity

My discussions of assisted suicide / death with dignity as a repugnant transaction included a recent post noting that in the most recent elections, Colorado joined the states (including California) that allow physicians to prescribe lethal drugs to mentally fit, terminally ill adults who want to end their lives.

It's therefore interesting to note that Supreme Court nominee Judge Neil M. Gorsuch has a 2006 book The Future of Assisted Suicide and Euthanasia suggesting that this is never justified. The publisher's website says:
 “The Future of Assisted Suicide and Euthanasia provides the most thorough overview of the ethical and legal issues raised by assisted suicide and euthanasia--as well as the most comprehensive argument against their legalization--ever published.”

In other (related) news, 
House committee moves to block D.C.’s assisted-suicide law

"In a rare step, a House committee voted 22 to 14 Monday night to block a law that would make assisted suicide legal in the District, opening a new front in the conflict between congressional Republicans and the overwhelmingly Democratic capital city.

It was one of only a handful of times in the four-decade history of D.C. home rule that members of Congress have tried to use their constitutional power to overturn a city law, and the first attempt since the GOP took control of both Congress and the White House in January.

The vote was largely along party lines, as 21 Republicans and one Democrat, Rep. Jim Cooper of Tennessee, voted yes while 13 Democrats and one Republican, Darrell Issa of California, voted no."
