"Black market" surrogacy in England, and subsequent legal complications

Organizing markets without a strong legal framework can be tricky; here's a British surrogacy story from the law blog Above the Law: I Want To Put A Baby In You: Underground Surrogacy And The Burger King Baby

"Last month, an English court held that a surrogate to an “underground” arrangement could nevertheless keep custody of the baby she carried. This was despite the fact that the surrogate was not genetically related to the child. Instead, she was hired via a “secret” matching service and matched with a gay couple. They hoped to be parents through surrogacy for a second time.
The intended parents and surrogate met only once for 30 minutes. Unfortunately, the meeting was at a Burger King. And now, this poor child is forever linked to the fast-food franchise.
After the meeting, the surrogate was flown to Cyprus. (As I mentioned previously, Cyprus is a hot destination for surrogacy arrangements.) There, she underwent the transfer of two embryos to her uterus. The eggs were from a donor, and one was fertilized by one of the intended parents and the second egg was fertilized with sperm from the other intended parent. The transfer was successful, and the surrogate became pregnant with twins. But sadly, she later miscarried one of the babies.
Issues continued to mount. The intended parents missed payment deadlines. The surrogate learned that the couple’s first surrogate had a negative review of the intended parents. Ultimately, the surrogate decided to keep the remaining child. She lied, and told the intended parents that she had miscarried both babies. But she was caught when the intended parents saw her very pregnant toward the end of the pregnancy.
The intended parents brought legal action against the surrogate to try to obtain their child. But they also had unclean hands. They had offered to “pay” the surrogate 9,000 pounds in exchange for carrying the baby. While British law allows “reimbursement” of expenses to a compassionate surrogate, no “paying” of a surrogate is permitted. Additionally, the court held that the surrogate herself had a learning difficulty that made her consent to the agreement invalid.
Ultimately, the court awarded full custody to the surrogate—I hope that learning difficulty isn’t too severe—while the intended parents get very limited visitation rights:  one weekend every eight weeks.
While it sounds shocking to award a surrogate the parental rights over a child to which they have no genetic connection, this unfortunately happens throughout the world. Even in the United States. And “underground” surrogacy arrangements are not unusual.
...
"the Chinese Ministry of Heath all but outlawed surrogacy in 2001. So the estimated 10,000 surrogacy births in China a year are all via its underground surrogacy industry. And due to the illegality of the arrangement, intended parents in China can lack legitimate parental rights to their children born via surrogacy."
...
"It Happens To U.S. Too. Surrogates change their minds in the United States as well. In the Robinson case, a gay couple in New Jersey asked the sister of one of the men to carry their children for them. Like the China case, this one also involves twin girls. The children were not related to the sister, but the result of an anonymous egg donor and the sperm from the spouse of her brother. After the girls were born, the relationship between the surrogate and the intended parents deteriorated..."

Acquiring the first thousand customers in a two-sided market

HBS Working Knowledge has a nice piece about a case study by Professor Thales Teixeira,

How Uber, Airbnb, and Etsy Attracted Their First 1,000 Customers

On Airbnb:
"founders Brian Chesky and Joe Gebbia thought like customers themselves, trying to figure out where they would go if Airbnb didn’t exist. It didn’t take them long to figure out the answer: Craigslist. The entrepreneurs figured they could do a better job of making apartments appealing than the online classified site, but first they had to siphon away its customers. To do that, Chesky and Gebbia created software to hack Craigslist to extract the contact info of property owners, then sent them a pitch to list on Airbnb as well.

The strategy worked. With nothing to lose, property owners doubled their chances of finding a potential renter, and Airbnb had a ready supply of homes with which it could attract customers."

Repugnant transactions in Saudi

The NY Times has an interesting story on Saudi Arabia: A Saudi Morals Enforcer Called for a More Liberal Islam. Then the Death Threats Began.

Some of the story focuses on repugnant transactions:

"Their embrace of technology runs counter to the history of Wahhabi clerics rejecting nearly everything new as a threat to the religion. Formerly banned items include the telegraph, the radio, the camera, soccer, girls’ education and televisions, whose introduction in the 1960s caused outrage."
...
"The government has sought to control the flow of religious opinions with official fatwa institutions. But state-sanctioned fatwas have provoked laughter, too, like the fatwa calling spending money on Pokemon products “cooperation in sin and transgression.
While the government seeks to get more women into the work force, the state fatwa organization preaches on the “danger of women joining men in the workplace,” which it calls “the reason behind the destruction of societies.”
And there are fatwas that arm extremists with religious justification. There is one fatwa, still available in English on a government website and signed by the previous grand mufti, that states, “Whoever refuses to follow the straight path deserves to be killed or enslaved in order to establish justice, maintain security and peace and safeguard lives, honor and property.”
It goes on: “Slavery in Islam is like a purifying machine or sauna in which those who are captured enter to wash off their dirt and then they come out clean, pure and safe, from another door.”

Medical tourism: cataract surgery in Britain

Britain is both an origin and a destination for medical tourism--travel to get better or cheaper medical care--and not everyone is happy to be on the receiving end.

The Telegraph has the story: Health tourists jump queue for cataract operations on NHS as British patients wait up to eight months

"Health tourists are being given cataract surgery on the NHS ahead of British patients because their conditions are considered more of a priority, it has emerged.

Hundreds of people from countries including Zimbabwe and Nigeria have been offered the eye operations before UK taxpayers, official figures show.

They have been fast-tracked by medics as their conditions are said to be "very complex and urgent", while some hospitals have waiting times of almost eight months.

Cataract surgery is the most common treatment provided on the NHS and 300,000 operations are carried out each year."

Donating a kidney today, and getting a promise of a living donor kidney in the future for someone you specify

Here's a news release from UCLA: ‘Gift certificate’ enables kidney donation when convenient and transplant when needed

"The program allows for living donors to donate a kidney in advance of when a friend or family member might require a kidney transplant.
...
"It is such a simple concept," Veale said. "It's the brainchild of a grandfather who wanted to donate a kidney to his grandson nearing dialysis dependency, but the grandfather felt he would be too old to donate in a few years when his grandson would likely need a transplant."

The release goes on to mention two such advanced donations that have already been made.
***********

Here's a related announcement: Voucher Allows You To Donate A Kidney Now, Secure One For Later

"Already, 9 other hospitals across the U.S. have joined UCLA and agreed to honor the voucher program. Recently, the Ethics Committee of the American Society of Transplant Surgeons also voted in favor of the voucher program and sent the matter to their executive committee for formal approval.  "

Investing in countries of first refuge, in return for integrating refugees into their economy

The NY Times has a story about Jordan: If a Carrot for Jordan Works, Syrian Refugees Will Stay Put

"Jordan, which has 650,000 Syrian refugees registered with the United Nations inside its borders, has long made it nearly impossible for them to work legally, citing concerns about high unemployment among its citizens. But under the new experiment, the government has given out 13,000 work permits to Syrians, and is promising to issue up to 50,000 by year’s end — and tens of thousands more in the future.

"In exchange, the World Bank is giving Jordan a $300 million interest-free loan, the likes of which are traditionally reserved for extremely poor countries in Africa. Western nations, including the United States, have offered roughly $60 million to build schools to accommodate Syrian children. And Jordan is close to clinching what it wants most: tax-free exports to the European Union, especially garments stitched in its industrial export zones.

"In short, Western leaders are using their financial and political leverage to convince Jordan that it is worthwhile to help refugees improve their lot in this country so they do not cross the Mediterranean Sea in flimsy rafts in search of a better life in Europe. It is a stark shift for both donor countries and Jordan, which, after absorbing generations of refugees from wars across the Middle East, had tried to keep Syrians from establishing a permanent foothold.

“Some may say this is the one shot that the government has to extract a lot of money,” Stefan Dercon, a professor at Oxford University and the chief economist at the British government’s development aid agency, which supports the effort in Jordan. “I would say it is also the only shot that it will have to really reform its economy and create jobs, with substantial international funding.”

"Jordan is not the only country trying to leverage Europe’s anxiety about refugees and migrants. Turkey has negotiated a deal that involves taking back most of those who traveled across the Aegean Sea into Greece in exchange for $6.6 billion in European aid and a proposed waiver of visas for Turks entering Europe.

"Europe is also promising over $4 billion in aid to several African countries in exchange for their help in stemming the exodus out of the continent. Even Sudan, long under European and American sanctions for its human rights record, is reaping money as part of the package. Libya is getting assistance from Europe to keep migrant boats from crossing the Mediterranean, an approach that Human Rights Watch describes as outsourcing “the dirty work to Libyan forces.”
...
"The Jordan deal, announced in February as part of the Jordan Compact, is described optimistically by its framers as “turning the Syrian refugee crisis into a development opportunity.” Its goal is to draw new foreign investment and create jobs for both Jordanians and Syrians. The risk, its proponents privately point out, is that no new investments will pour in, Jordan’s economy will continue to languish and local resentment will grow.

"Until recently, barely 5,000 Syrian refugees had work permits. The International Labor Organization, a United Nations agency that supports and devises work policies, estimated that 50,000 people in Jordan worked off the books — roughly the number that the government is promising to legalize this year alone.

For Jordan’s leaders, grappling with debt and an economy growing at an anemic 2.4 percent, access to the European market is a critical incentive."

Market design and cultural context: from an interview in Japan

When I was in Japan in April I spoke at Tokyo Institute of Technology. Here's a brief account that just appeared in English, highlighting some remarks I made that markets have cultural contexts: Professor Alvin E. Roth interviewed in Contemporary Society class

"A student asked why Roth engages in fieldwork such as operating room visits to conduct his research. The professor pointed out that markets have too many unwritten rules and are too complex to understand only through books. There are also many culture-related rules that need to be learned through direct experience. If someone designs the Japanese market, that person should be Japanese, someone who truly understands Japanese culture. This comment visibly moved the audience and will undoubtedly motivate students as they pursue their future study and research activities."

Howard Raiffa (1924-2016)

Multiple emails this morning tell that Howard Raiffa passed away peacefully last night. He was an early game theorist, a hero of decision theory, and an institution builder (as well as an institution) at Harvard and elsewhere. (He was also the advisor of my advisor, Bob Wilson.) A gentle man and an intellectual giant.

Here is a picture of Howard and Estelle I took at dinner in Cambridge in 2012. They were high school sweethearts, throughout their long life together.

Updates:

July 11: here's the email announcement from HBS
"To:  HBS Community
From:  Nitin Nohria
Re:  Sad news -- Howard Raiffa

I am very sorry to let you know that Howard Raiffa died peacefully at his home in Arizona on Friday July 8 following a long battle with Parkinson's.  He was 92 years old.  He is survived by his wife, Estelle, and his two children, Mark and Judy.

Howard, the Frank Plumpton Ramsey Professor of Managerial Economics, came to Harvard Business School in 1957 through the generosity of the Ford Foundation as one of a small cadre of discipline-based scholars.  He was interested in the resolution of conflict through mediation and arbitration, and several times during his career he either invented an entirely new field or changed an existing field so fundamentally that he earned recognition as its reinventor -- from decision analysis to game theory to negotiation analysis.  He authored and co-authored seminal works such as Applied Statistical Decision Theory and Decisions With Multiple Objectives.  An epitome of One Harvard before the phrase was coined, he interests spanned boundaries, and he is credited as a founder of the modern Kennedy School (where he held a joint appointment beginning in 1969) and had close ties as well with the Law School and School of Public Health.  He also served as the founding director of the International Institute for Applied Systems Analysis in Austria.

Here at HBS, he was gentle and demanding mentor to many, and a friend and colleague to many more.  While he officially retired from the faculty in 1994 he remained on as an advisor for some time after.

While we do not yet know of plans for a memorial service, we will be sure to communicate any information as it is learned, as well as a full obituary once it is finalized.

Our thoughts and sympathies are with his family and other loved ones."

Howard Raiffa, Mathematician Who Studied Decision Making, Dies at 92
"Howard Raiffa was born in the Bronx on Jan. 24, 1924, the son of Jacob Raiffa, who sold wool products, and the former Hilda Kaplan. He graduated from Evander Childs High School, where he was captain of the basketball team. Math was his best subject, but he dreamed of being a basketball player or coach.

He was attending City College when he enlisted in the Army Air Corps, where he was a radar specialist. He earned a bachelor’s degree in mathematics in 1946, a master’s in statistics and a doctorate in mathematics, all from the University of Michigan in Ann Arbor.

In 1945, he married Estelle Schwartz. She and his daughter survive him, as do a son, Mark, and four grandchildren."

Kidney exchange and school choice in German (two interviews)

School choice in Indianapolis

The Indy Star has the story on the changes to come: School choice made easier for Indy parents

"The good news is that change is coming. A new non-profit organization, Enroll Indy, launched by a Mind Trust Education Entrepreneur Fellowship, is working with Indianapolis Public Schools, the Mayor’s Office and the State Charter School Board to streamline the school application process for public school families. Its plan includes a new school information source for parents to learn about their options; a robust effort to work directly with families on navigating the process; a streamlined application that includes both IPS and charter schools; a shared deadline across all schools and a much-needed window of transparency into school enrollment.
For nearly a year, stakeholders in both IPS and the charter sector have worked together on recommendations focused on making enrollment more efficient, equitable and transparent. As such, Enroll Indy is poised to launch a system this fall that will dramatically improve access for all families.
This new system not only will make the enrollment process easier for all families, but it will provide robust data and information to our city as a whole. It will provide new information on the type of schools families want and where they want them, meaning districts and authorizers will be able to collaborate strategically to meet the needs of families, rather than starting schools with no information on the neighborhood’s needs or wants. This data also will enable us to ensure schools are behaving fairly and serving all students, not just those who are easiest to educate."

The global system of refugee protection


I'm at the Center for Migration Studies (CMS*) in New York, attending a conference on the global system of refugee protection, and how it interacts with a myriad of related concerns, among which security has become prominent.

Refugee protection/resettlement is a wicked problem, in all the senses of the word. After the first day of discussion I have to admit its complexity is head-breaking.

Everything having to do with refugee resettlement is complicated by the highly charged political environment in which it is now discussed, and the big consequences this can have. For example, Fiona Adamson of the University of London's School of Oriental and African Studies showed some refugee/migrant-inspired posters from the recent Brexit campaign to take Britain out of Europe, like this one.

Campaign against research misconduct in the Netherlands

Inside Higher Ed has the story: The Dutch Fight for Research Integrity (and the url is more informative than the headline--https://www.insidehighered.com/news/2016/06/23/netherlands-starts-major-campaign-against-research-misconduct )

"There are two parts of the Dutch investigation into research integrity: a program called Fostering Responsible Research Practices, which will include a national survey of researchers and research grants into the area, and a fund for replication studies of important “cornerstone” research that has been relied on to make policy or has attracted lots of media attention.
The programs are set to be signed off soon and calls for proposals are expected before the end of the summer.
The mass survey of researchers in the Netherlands will encompass all disciplines, including humanities scholars, who, like scientists, can be “selective” in their use of sources, he said. The anonymized results will be reported back to universities so they can judge the extent of the problem."

The papers are by and large critical of recent reforms, including school choice.  New Orleans Recovery School District has mostly charter schools.
**********

And here's a paper just published in the AER that looks at the effects of charter schools, using the fact that some non-charters have been taken over, which changes the selection criteria (students already in a takeover school are grandfathered in...)

American Economic Review 2016, 106(7): 1878–1920
Atila Abdulkadiroğlu, Joshua D. Angrist, Peter D. Hull and Parag A. Pathak
Charter takeovers are traditional public schools restarted as charter schools. We develop a grandfathering instrument for takeover attendance that compares students at schools designated for takeover with a matched sample of students attending similar schools not yet taken over. Grandfathering estimates from New Orleans show substantial gains from takeover enrollment. In Boston, grandfathered students see achievement gains at least as large as the gains for students assigned charter seats in lotteries. A non-charter Boston turnaround intervention that had much in common with the takeover strategy generated gains as large as those seen for takeovers, while other more modest turnaround interventions yielded smaller effects.

Civil servants study market design in Melbourne

The Centre for Market Design in Melbourne is offering a course leading to a Specialist Certificate in Economic Design:

"Sixty international and national government decision makers completed the Specialist Certificate in Economic Design in Canberra last Friday (24 June 2016) with the aim of deepening their economic knowledge.
"The new graduate course, accredited by the University of Melbourne, and developed and taught by the Centre for Market Design (CMD) brings policymakers up-to date with the latest developments in microeconomics.
"It provides public servants with a conceptual framework for analysing policies and evaluating their effect, with emphasis on the resource and information constraints policymakers and market designers face.
...
"Economic design includes the design of procurement mechanisms and sales auctions, double-auctions in two-sided markets, algorithms for matching (e.g. students to schools, or children to kindergarten), and the writing of performance contracts.

Can a family that has decided to end life support decide a loved one should be a living donor?

Transplantation is a field full of the kind of wrenching discussions that you might expect to find as hypotheticals in a philosophy class. The WSJ follows one such discussion:
The Difficult Ethics of Organ Donations From Living Donors

"The family proposed that doctors put Mr. Osterrieder under anesthesia and perform surgery to remove a kidney for transplant. Like any living donor, he would be expected to survive the procedure. Then, a few days later, the ventilator would be removed and he would be allowed to die.

“Just the feeling something good would come out of this helped us,” says Kim Shuster, 31, one of Mr. Osterrieder’s daughters.

"A labyrinth of federal and state rules and regulations, as well as those of individual transplant centers, guide organ procurement. The family met with the hospital’s ethics committee, spoke with doctors and talked among themselves. Everyone wanted to make sure the choice reflected Mr. Osterrieder’s wishes, but there was also discussion about how the family might feel if their decision made news and strangers, not to mention relatives, criticized them.

"Kathy Osterrieder says she, her children and son-in-law all agreed, “if any of us are not on board, we won’t do this.” Whatever happens, she told them, “we have to survive as a unit.”

"The ethics committee gave its approval, and the hospital reached out to the federally designated organ-procurement service that helps coordinate donations in the region. The organization’s leaders were moved. But when they put out a call to 14 different transplant centers to find a surgeon to perform the operation, “we could not find a surgeon who was willing,” says Kurt Shutterly, chief operating officer of the Center for Organ Recovery and Education, based in Pittsburgh.

"The surgeons didn’t feel it was ethical to remove Mr. Osterrieder’s kidney without his direct authorization, Mr. Shutterly recounts. They also worried, he says, that if a living donor died soon after the procedure, it might jeopardize an institution’s entire transplant program.
...
"Earlier this year, an Organ Procurement and Transplantation Network and UNOS working committee wrote a report about the ethical considerations of a type of “imminent-death donation,” in which a living donor through a surrogate donates an organ before the planned withdrawal of ventilator support. The committee found that, under certain circumstances, the practice may be ethical, but some people who read the report expressed significant enough concerns that the committee determined, for now at least, that it didn’t want to move forward with trying to change UNOS policy. The report is expected to be posted soon for public comment.

“It is powerful to think that someone at the end of life, who has suffered a lot of illness, would want to do something to help someone else by being a living donor,” says Peter Reese of the University of Pennsylvania, chairman of the OPTN/UNOS ethics committee.

"And yet, despite the fact that offering an organ is an exquisitely personal decision, transplantation is a highly communal process, from the involvement of many medical disciplines in the extraction of the organ to the decision about who receives it. “If all those people don’t agree and we try to push this forward, we run the risk of undermining the whole enterprise,” Dr. Reese says. “Organ transplantation requires public trust to a massive degree.”

Who finds sales of genetically modified food repugnant? (Hint: they are disgusted)

Here's a paper on a source of firm opposition to genetically modified food:

Sydney E. Scott, Yoel Inbar, and Paul Rozin
Evidence for Absolute Moral Opposition to Genetically Modified Food in the United States
Perspectives on Psychological Science May 2016 11: 315-324

Abstract

Public opposition to genetic modification (GM) technology in the food domain is widespread (Frewer et al., 2013). In a survey of U.S. residents representative of the population on gender, age, and income, 64% opposed GM, and 71% of GM opponents (45% of the entire sample) were “absolutely” opposed—that is, they agreed that GM should be prohibited no matter the risks and benefits. “Absolutist” opponents were more disgust sensitive in general and more disgusted by the consumption of genetically modified food than were non-absolutist opponents or supporters. Furthermore, disgust predicted support for legal restrictions on genetically modified foods, even after controlling for explicit risk–benefit assessments. This research suggests that many opponents are evidence insensitive and will not be influenced by arguments about risks and benefits.
