The UAE may soon allow organ transplants

The Gulf News has the story. (I hadn't realized that transplantation was a repugnant transaction in the United Arab Emirates. In fact it sounds as if they still have a way to go...)

The UAE may soon allow organ transplant--Some 68% of respondents on a UAE national survey said they were willing to donate organs if they were brain-dead

"The deceased organ donation programme, which is now available in all other GCC countries except for the UAE, might soon become a reality in this country too, said Dr Farhad Janahi, assistant professor and renowned kidney transplant surgeon at Mohammad Bin Rashid University of Medicine and Health Sciences (MBRU) at the Dubai Health Care City (DHCC).
...
"Dr Janahi told Gulf News: “At present there are over 2,000 kidney patients on dialysis in the UAE on a waiting list for kidney transplants alone. Deceased organ donation programme is now a reality in all other Gulf Cooperation Council countries and this survey’s findings indicate that the people of UAE are ready for a new law on deceased organ donation.”
...
"The results of this survey were presented at the first UAE Organ Donation forum held last week at the DHCC which was held under the patronage of the Chairperson of Dubai Health Care City Authority (DHCCA), Princess Haya Bint Al Hussain, wife of His Highness Shaikh Mohammad Bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, and was attended by 50 transplant experts, religious leaders and donors, among other attendees, and also highlighted means to expand organ transplantation services in the UAE.
...
"Dr Amer Ahmad Sharif, chief executive officer, Education Sector, DHCCA, said, “Creating a platform such as the first UAE Organ Donation Forum to discuss legislations, exchange ideas will help us reduce the gap between the demand and supply of human organs for transplantation.”

Clearinghouses for IOU's in the 13th through 18th centuries: by Borner and Hatfield

Here's a market design/economic history paper about early financial clearinghouses, forthcoming in the Journal of Political Economy:

The Design of Debt Clearing Markets: Clearinghouse Mechanisms in Pre-Industrial Europe
Lars Borner, and John William Hatfield

Abstract
We examine the evolution of the decentralized clearinghouse mechanisms that were
in use throughout Europe from the 13th century to the 18th century; in particular,
we explore the clearing of non- or limited-tradable debts like bills of exchange. We
construct a theoretical model of these clearinghouse mechanisms and show that the
specific decentralized multilateral clearing algorithms known as rescontre, skontrieren
or virement des parties, used by merchants in this period, were efficient in specific historical
contexts. Our analysis contributes to the understanding of both the emergence
and evolution of these mechanisms during late medieval and early modern fairs and
their robustness during the 17th and 18th centuries.

Georgia plans national matchmaking service as marriage rate falls (the country, not the U.S. state)

The Guardian has the story:
Georgia plans national matchmaking service as marriage rate falls
National database of singletons proposed to help pull country away from ‘demographic catastrophe’.

"A nationwide headcount of eligible bachelors and bachelorettes has been announced in Georgia, apparently in a bid to help tackle the slowing birth rate.

Georgia’s non-profit Demographic Development Fund (DDF) believes that a drop in the rate of marriages and births has brought the small post-Soviet nation to the cusp of a “demographic catastrophe”.

They say apps such as Tinder won’t adequately tackle the problem, and that a government-backed dating service is needed instead.

“We will take a census of all singles, widows, widowers, the divorced and enter their details in a database,” Davit Khizanishvili, the fund’s president, announced.

The DDF has already started to profile Georgia’s singletons, taking note of personal details such as “weight, height and zodiac sign” and adding them to the database, which they say will be administered by a special agency."

Results of the 2015 Medical School Enrollment Survey

Results of the 2015 Medical School Enrollment Survey

"Key findings include:
 • Medical school enrollment has grown 25 percent since 2002–2003, and 30 percent growth should be achieved by 2017–2018. In 2006, in response to concerns of a likely future physician shortage, the AAMC recommended a 30 percent increase in first-year medical school enrollment by the 2015–2016 academic year (over 2002–2003 levels). Using the baseline of the 2002–2003 first-year enrollment of 16,488 students, a 30 percent increase corresponds to an increase of 4,946 students. The survey results indicate that the 30 percent goal will likely be attained by 2017–2018. Enrollment growth could be accelerated if any of the seven applicant or candidate schools in the Liaison Committee on Medical Education (LCME) pipeline attains preliminary accreditation.

• Schools are increasingly concerned about the availability of graduate medical education opportunities for their incoming students. Medical schools reported concern about enrollment growth outpacing growth in graduate medical education (GME). Half of medical schools reported concerns about their own incoming students’ ability to find residency positions of their choice after medical school, up from 35 percent in 2012. Concern about GME availability at the state and national levels declined somewhat since 2013, yet it still remained high.

• There has been a large increase in the percentage of schools experiencing competition for clinical training sites from DO-granting schools and other health care professional programs. In 2015, 85 percent of respondents expressed concern about the number of clinical training sites and the supply of qualified primary care preceptors. Seventy-two percent expressed concern about the supply of qualified specialty preceptors. There has been a large increase in the percentage of schools experiencing competition from DO-granting schools and other health care professional programs, from about a quarter of schools in 2009 to more than half of schools in 2015. Forty-four percent of respondents reported feeling pressure to pay for clinical training slots, though the majority of schools currently do not pay for clinical training.
...
• Enrollment increases at DO-granting schools continue to accelerate. First-year enrollment at DO-granting schools in 2020–2021 is expected to reach 8,468, a 185 percent increase from 2,968 students in 2002–2003. Combined first-year enrollment at existing MD-granting and DO-granting medical schools is projected to reach 30,186 by 2020–2021, an increase of 55 percent compared with 2002–2003. "

Organizing organ donation by social media

In the NY Times, David Bornstein writes about the efforts by Organize to bolster organ donor registries by prompting statements of intent on internet media:
Using Tweets and Posts to Speed Up Organ Donation

"One group attacking the question is Organize, which was founded in 2014 by Rick Segal’s son Greg, and Jenna Arnold, a media producer and educator who has worked with MTV and the United Nations in engaging audiences in social issues. Organize uses technology, open data and insights from behavioral economics to simplify becoming an organ donor.

This approach is shaking up longstanding assumptions.

For example, in the last four decades, people have most often been asked to register as an organ donor as part of renewing or obtaining a driver’s license. This made sense in the 1970s, when the nation’s organ procurement system was being set up, says Blair Sadler, the former president and chief executive of Rady Children’s Hospital in San Diego. He helped draft the Uniform Anatomical Gift Act in 1967, which established a national legal framework for organ donation. “Health care leaders were asking, ‘How do we make this more routine?’” he recalled. “It’s hard to get people to put it in their wills. Oh, there’s a place where people have to go every five years” — their state Department of Motor Vehicles.

Today, governments allow individuals to initiate registrations online, but the process can be cumbersome. For example, New York State required me to fill out a digital form on my computer, then print it out and mail it to Albany. Donate Life America, by contrast, allows individuals to register online as an organ donor just by logging in with email or a Facebook or Google account — much easier.

In practice, legal registration may be overemphasized. It may be just as important to simply make your wishes known to your loved ones. When people tell relatives, “If something happens to me, I want to be an organ donor,” families almost always respect their wishes. This is particularly important for minors, who cannot legally register as donors.

Using that insight, Organize is making it easier to conduct social media campaigns to both prompt and collect sentiments about organ donation from Facebook, Twitter and Instagram.

If you post or tweet about organ donation, or include a hashtag like #iwanttobeanorgandonor, #organdonor, #donatemyparts, or any of a number of other relevant terms, Organize captures the information and logs it in a registry. In a year, it has gathered the names of nearly 600,000 people who declare support for organ donation. Now the big question is: Will it actually increase organ donation rates?

We should begin getting an idea pretty soon. Organize has been working with the Nevada Donor Network to test its registry. And in the coming months, several other states will begin using it."

Mathematical Matchmaking--Algorithms That Address Real-World Problems

By James Case

Who Gets What—And Why. By Alvin E. Roth, Houghton Mifflin Harcourt, New York, 2015, 272 pages, $28.00.

Case likes the book but warns the non-economist reader as follows:
"In closing, it should be mentioned that by classifying matchmaking venues as markets, Roth gives the impression that economists are uniquely qualified to design and modify them, though nothing in the traditional economics curriculum seems particularly relevant. On the contrary, students of combinatorics, computer science, and/or operations research (in which Roth himself received his doctoral degree) would seem at least as well prepared for the task. "

A repugnant gun transaction

USA Today has the story of the on again, off again and once more on again auction of a notorious gun:
George Zimmerman's auction of Trayvon Martin gun back on
The url is more informative:  http://www.usatoday.com/story/news/2016/05/12/george-zimmerman-auctions-gun-used-trayvon-martin-killing/84271998/

"George Zimmerman tried a second time Thursday to auction off the firearm he used to kill 17-year-oldTrayvon Martin in Florida in 2012 after the first gun-selling website yanked the listing minutes before bidding was to begin on the "piece of history."

A statement posted on the website GunBroker.com said listings are user generated, and that the company reserved the right to reject any at its discretion.

"Mr. Zimmerman never contacted anyone at GunBroker.com prior to or after the listing was created and no one at (the website) has any relationship with Zimmerman," the company wrote in its statement.

It added, "We want no part in the listing on our web site or in any of the publicity it is receiving."

The listing, which got more than 185,000 views, was replaced at mid-morning Thursday by a message that said, without elaboration, "Sorry, but the item you have requested is no longer in the system."

Zimmerman told the Orlando Sentinel that GunBroker.com was not "prepared for the traffic and publicity surrounding the auction of my firearm. It has now been placed with another auction house."

The new listing for the Kel-Tec PF-9 9mm firearm was posted on unitedgungroup.com.

Zimmerman wrote in both listings that that he was "honored and humbled" to announce the sale of the weapon and set the bidding to start at $5,000. Similar firearms normally sell on the site for around $200.

"The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin on 2/26/2012," he wrote.

Zimmerman, 32, noted the Justice Department returned the weapon to him recently and it still bears the case number written on it in silver permanent marker.

"This is a piece of American History," he wrote. "It has been featured in several publications and in current University text books."

Zimmerman, then a neighborhood watch volunteer, shot and killed Trayvon in February 2012, in a confrontation as the unarmed teenager was heading back to a relative's house in Sanford, Fla., after buying snacks at a convenience store.

A jury found Zimmerman, who alleged that Martin was trying to bash his head on the pavement during a struggle, not guilty of second-degree murder and manslaughter."

Should prostitution remain illegal in the U.S?

The NY Times is on the case:

Should Prostitution Be a Crime?

A growing movement of sex workers and activists is making the decriminalization of sex work a feminist issue.

By EMILY BAZELONMAY 5, 2016

"Three months earlier, at a meeting attended by about 500 delegates from 80 countries, Amnesty voted to adopt a proposal in favor of the “full decriminalization of consensual sex work,” sparking a storm of controversy. Members of the human rights group in Norway and Sweden resigned en masse, saying the organization’s goal should be to end demand for prostitution, not condone it. Around the world, on social media and in the press, opponents blasted Amnesty.
...
"In the United States and around the globe, many sex workers (the term activists prefer to “prostitute”) are trying to change how they are perceived and policed. They are fighting the legal status quo, social mores and also mainstream feminism, which has typically focused on saving women from the sex trade rather than supporting sex workers who demand greater rights. But in the last decade, sex-worker activists have gained new allies. If Amnesty’s international board approves a final policy in favor of decriminalization in the next month, it will join forces with public-health organizations that have successfully worked for years with groups of sex workers to halt the spread of H.I.V. and AIDS, especially in developing countries. “The urgency of the H.I.V. epidemic really exploded a lot of taboos,” says Catherine Murphy, an Amnesty policy adviser.
...
"At the Amnesty conference, Muñoz told the crowd that she thinks decriminalization would have benefits for many people by bringing the sex trade out from underground. “I believe in the empowered sex worker,” she said. “I was one. But the empowered sex worker isn’t representative of the majority of sex workers. It’s O.K. for us to be honest about this.” She was referring to the social and economic divide in the profession. Activists in the sex-workers’ movement tend to be educated and make hundreds of dollars an hour. The words they often use to describe themselves — dominatrix, fetishist, sensual masseuse, courtesan, sugar baby, whore, witch, pervert — can be self-consciously half-wicked.

Some of their concerns can seem far removed from those of women who feel they must sell sex to survive — a mother trying to scrape together the rent, say, or a runaway teenager. People in those situations generally don’t call themselves “sex workers” or see themselves as part of a movement. “It’s not something people we work with would ever talk about,” says Deon Haywood, the director of Women With a Vision in New Orleans, an African-American health collective that works with low-income women and trans clients. Some of them sell sex, Haywood says, because it’s more flexible and pays better than low-wage work at businesses like McDonald’s.

Human rights advocates tend to focus on people in grim circumstances. “Like many feminists, I’m conflicted about sex work,” says Liesl Gerntholtz, executive director of the women’s rights division at Human Rights Watch, which took a stand in favor of decriminalization four years ago. “You’re often talking about women who have extremely limited choices. Would I like to live in a world where no one has to do sex work? Absolutely. But that’s not the case. So I want to live in a world where women do it largely voluntarily, in a way that is safe.

Buying old drugs and raising their price is a repugnant transaction on Capitol Hill

Valeant Chief, at Senate Hearing, Concedes Mistakes on Steep Drug Prices

"The chief executive of Valeant Pharmaceuticals International, which has been harshly criticized for its practice of raising prices on old drugs, said during a tense hearing on Capitol Hill on Wednesday that the company had made “mistakes,” while lawmakers accused him and others connected to Valeant of favoring profits over patients’ needs.

“Let me state plainly that it was a mistake to pursue, and in hindsight I regret pursuing, transactions where a central premise was a planned increase in the prices of the medicines,” J. Michael Pearson, the chief executive, said at the hearing."

Los Angeles starts to discuss common enrollment school choice

The LA Times has the story:
How realistic is L.A. Unified's common enrollment application plan?

"According to a report that district employees prepared for the board of education in October and obtained by The Times in April, the district would favor a website like that of Boston Unified School District, in which parents can come to one website, enter their preferences for their child and receive suggestions on schools that fit the criteria. The information technology department recommended hiring a vendor to create this "search engine," according to the report.

The paper also suggests moving the application timeline to the fall semester, and creating one common application for all L.A. Unified schools. This would allow the district to compete with charter schools that have their lotteries early in the school year.

Unlike some other districts that have adopted this kind of process, L.A. Unified would not include independent charters. During a budget meeting in March, superintendent Michelle King told board members this single enrollment system would be a way to keep students, and the revenues they bring, in traditional public schools.

The discussions come as more students abandon district schools in favor of charter schools.

Right now there are about 10 kinds of public school options for families, including neighborhood schools, magnets, open enrollment, and zones of choice. Even if parents know that they have options and figure out what the alphabet soup of words means, the enrollment and application dates are at different times of the year, from October through March."

Matching with (sexual) contracts, by Arcidiacono, Beauchamp, and McElroy

Quantitative Economics, Volume 7, Issue 1 (March 2016)

Terms Of Endearment: An Equilibrium Model Of Sex And Matching

Peter Arcidiacono, Andrew Beauchamp, Marjorie McElroy

Abstract

We develop a two‐sided directed search model of relationship formation that can be used to disentangle male and female preferences over partner characteristics and over relationship terms from only a cross section of observed matches. Individuals direct their search for a partner on the basis of (i) the terms of the relationship, (ii) the partners' characteristics, and (iii) the endogenously determined probability of matching. Using data from the National Longitudinal Study of Adolescent Health, we estimate an equilibrium matching model of high school relationships. Variation in gender ratios is used to uncover male and female preferences. Estimates from the structural model match subjective responses on whether sex would occur in one's ideal relationship. The estimates show that some women would ideally not have sex, but do so out of matching concerns; the reverse is true for men. Counterfactual simulations show that the matching environment black women face is the primary driver of the large differences in sexual activity among white and black women.
