"Tissue rights"

Who has the rights to a cell line created from cancerous tissue? The NY Times reviews the book “The Immortal Life of Henrietta Lacks” (Crown Publishers), by the journalist Rebecca Skloot.

A Lasting Gift to Medicine That Wasn’t Really a Gift

"The notion of “tissue rights” has inspired a new category of activists. The question that comes up repeatedly is, if scientists or companies can commercialize a patient’s cells or tissues, doesn’t that patient, as provider of the raw material, deserve a say about it and maybe a share of any profits that result? Fewer people these days may be willing to take no for an answer. "

Embryo exchange in Georgia

It's not what it sounds like, and it doesn't have tax consequences:

Embryo Exchanges and Adoption Tax Credits by
Sarah B. Lawsky and Naomi Cahn

Abstract: The “Option of Adoption Act,” a Georgia law that was introduced by a staunchly anti-abortion Georgia state representative, establishes procedures for genetic donors to relinquish their rights to embryos before birth and permits, but does not require, embryo recipients to petition a court for recognition that they are the legal parents of a child born to them as a result of an embryo transfer. This article clears up what seems to be widespread confusion about a fairly straightforward question of tax law related to such embryo “adoptions.” Notwithstanding various sources' claims to the contrary, neither a Georgia adoption tax credit nor a federal adoption tax credit is available for “adopting” an embryo.

Matching for adoption

"In most cases, a successful domestic adoption is the result of a match between a birth mother (BMO hereafter) who seeks to relinquish her child, and prospective adoptive parents (PAPs hereafter). The underlying matching process involves a bilateral search characterized by several layers of mediation: Typically, adoption agencies represent BMOs, while PAPs work vis-à-vis adoption agencies, lawyers, or facilitators. In this paper, we exploit the unique nature of a new data set documenting the operations of an adoption facilitator. We analyze the preferences of PAPs over the attributes of babies relinquished for adoption, the BMOs’ choices, and the factors that determine ultimate outcomes (i.e., a successful adoption, a decision to parent by the BMO, or the child’s placement in foster care).

That is from the paper Gender and Racial Biases: Evidence from Child Adoption, by Mariagiovanna Baccara , Allan Collard-Wexler, Leonardo Felli , and Leeat Yariv.

The paper has a market design aspect:
"Despite the social value of a well-functioning matching process that delivers suitable parents to every child, adoption has not received much attention by the economics literature. Our analysis of parents’ preferences, combined with the identification of factors facilitating an ultimate match, opens the door to policy interventions aimed at increasing the efficiency of this process."

Same sex marriage in Mexico City: starting today

Gay Marriage Puts Mexico City at Center of Debate : "A new Mexico City law goes into effect March 4 that will allow same-sex couples to marry and adopt children, propelling the city to the forefront of the global gay rights movement."
The law seems to have survived the expected judicial challenge: Mexico's Supreme Court Upholds Gay Marriage Law , and here's a nice story about the (ongoing) debate in yesterday's Washington Post, With same-sex marriage law, Mexico City becomes battleground in culture wars

Here are my other posts on same sex marriage, which strikes me as an excellent example of how views and laws can change regarding repugnant transactions.

Same sex marriage in Washington D.C., starting yesterday

Gay Marriage Is Now Legal in Washington
"Gay-rights advocates hailed the day as a milestone for equal rights and a symbolic victory as same-sex marriage became legal in the nation’s capital.
Washington is now the sixth place in the nation where same-sex marriages can take place. Connecticut, Iowa, Massachusetts, New Hampshire and Vermont also issue marriage licenses to same-sex couples.
Despite failing in court, opponents of the law vowed to fight another day. "

And here is the failure in court:
SUPREME COURT OF THE UNITED STATES No. 09A807
HARRY R. JACKSON ET AL. v. DISTRICT OF COLUMBIA BOARD OF ELECTIONS AND ETHICS ET AL. ON APPLICATION FOR STAY
[March 2, 2010] CHIEF JUSTICE ROBERTS, Circuit Justice.

"Petitioners in this case are Washington D. C. voters who would like to subject the District of Columbia’s ReligiousFreedom and Civil Marriage Equality Amendment Act of 2009 to a public referendum before it goes into effect... Without addressing the merits of petitioners’ underlying claim, however, I conclude that a stay is not warranted. "

Same sex unions in the Anglican church

Across the pond: Anglican bishops back end to ban on gay civil partnerships in church "Gay couples could soon be allowed to “marry” in church after a decision by Anglican bishops and other clergy to support a relaxation of the ban. Senior bishops in the Lords have told The Times that they will support an amendment to the Equality Bill next month that will lift the ban on civil partnership ceremonies in religious premises. The amendment would remove the legislative prohibition on blessings of homosexual couples and open the door to the registration of civil partnerships in churches, synagogues, mosques and all other religious premises." ... "The Church of England, which along with the wider Anglican Communion is divided over gay ordinations and same-sex blessings, will maintain its official ban. But if the legislative prohibition is lifted, as seems likely, the Church’s own ban is likely to be ignored by some clergy." ... "The Quakers have called for the law to be changed to give same-sex partners the same status in their ceremonies as heterosexual couples. They joined forces with Liberal Judaism and the Unitarians to support an amendment to the Equality Bill giving religious organisations the freedom to register civil partnerships. Lord Alli’s amendment would remove the bar in the Civil Partnership Act 2004 on religious premises being used for civil partnerships — and also the prohibition on religious language being used in such ceremonies. This would in effect end any remaining distinction between civil partnerships and marriage and increase the pressure on the established Church to take a more liberal line on same-sex relationships. It would also deepen the schism in the Anglican Communion over gay blessings and gay ordination."

Academic job markets in the Humanities

The American Academy of Arts and Sciences has issued a new report as a result of a set of surveys of Humanities departments. Here is the announcement:

"Challenges to Humanities Revealed in New Survey
The humanities continue to play a core role in higher education and student interest is strong, but to meet the demand, four-year colleges and universities are increasingly relying on a part-time, untenured workforce. Those are among the findings from the Humanities Departmental Survey. The survey includes data collected from English, foreign language, history, history of science, art history, linguistics, and religion departments at approximately 1,400 colleges and universities. It is the first comprehensive survey to provide general cross-disciplinary data on humanities departments. "

"Across the humanities, but especially in English and combined English/foreign language departments, the professoriate at four-year colleges and universities is evolving into a part-time workforce. During the 2006-2007 academic year, only 38 percent of faculty members in these departments were tenured. English departments had the greatest proportion of non-tenure-track faculty (49 percent)."

Assisted suicide, the debate continues in England and Switzerland

Assisted suicide, a widely repugnant transaction, continues to be the subject of public discussion in England. The Telegraph reports a new poll: Assisted suicide: 4 in 5 say do not prosecute.

"The public’s support for a change in the law on assisted suicide and euthanasia was uncovered by the YouGov poll following a succession of high profile court cases.
Three quarters of those polled said the law should be amended to allow assisted suicide, a crime punishable by up to 14 years in prison. "...

"Sir Terry Pratchett, the author who suffers from Alzheimer’s disease, is due to deliver a lecture in which he will call for assisted suicide "tribunals" that would give the terminally ill permission to end their lives. In the Richard Dimbleby Lecture, he will offer himself as a test case for just such a tribunal... Sir Terry, who prefers the term "assisted death", will say that permission to end his life will make each day more precious, and that doctors should not be forced to help the terminally ill to die. ... "If I knew that I could die, I would live. My life, my death, my choice." "

The WSJ has an article about the Swiss assisted suicide clinic Dignitas, and the debate going on in Switzerland about the the laws governing assisted suicide:
Assisted-Suicide Pioneer Stirs a Legal Backlash

"From the start, Mr. Minelli has kicked up controversy for his willingness to help foreigners die. Most groups in Switzerland don't assist foreigners. Dignitas only helps foreigners. The number of foreigners Dignitas helps each year—132 in 2007, compared to 91 in 2003—has increasingly left the Swiss uncomfortable with the country's growing reputation for "suicide tourism." As of the end of last year, Dignitas had helped a total of 1,046 people to commit suicide. "...

"Under Swiss law, it is illegal for a person to assist a suicide for their own "selfish" reasons. But there are otherwise no limits on helping someone to die. By contrast, most countries allowing assisted suicide require the person to be terminally ill or demand that a doctor assist the suicide. Switzerland is also the only country permitting right-to-die organizations to help foreigners die.
"At the moment, there is really no law," says Andreas Brunner, a Zurich prosecutor who has fought for greater restrictions on right-to-die organizations, particularly Dignitas. "You have to have some rules and standards. The worst solution is what we have now."
As medical advances prolong lives even for the seriously ill, the debate over assisted suicide is surging elsewhere.
In Oregon—the one state in the U.S. where assisted suicide is legal—doctors are allowed to help only state residents who are expected to die within six months.
The U.K., which has restrictive laws on euthanasia, was forced in a court case last fall to clarify whether it would prosecute Britons who help family members make the trip to Switzerland to die. (It won't.) Luxembourg legalized euthanasia last year. Activists in Belgium and the Netherlands are pushing to broaden the group of patients who can avail themselves of assisted suicide to the elderly, minors and chronically ill. "...

"In 2008, when neighbors' complaints forced Dignitas out of the rented apartment it had long used for suicides, Zurich city officials refused permission for a new venue.
So, Mr. Minelli organized suicides in cars, a hotel room and his own home, drawing the ire of local officials. For a time, he was forced to use the industrial site criticized by Mr. Gall. "Someone who is used to a five-star hotel can't come to Dignitas and expect the same," Mr. Minelli says.
The Zurich prosecutor's office spoke with family members who complained about the 10,000-Swiss-franc fee Mr. Minelli charges people to die, but found insufficient grounds to open an inquiry. One rival right-to-die organization asks for nothing beyond a 45-Swiss-franc membership fee, while another charges 4,000 Swiss francs. Mr. Minelli says the fee helps with his legal and lobbying expenses. "...

"Mr. Minelli argues that making assisted suicide available removes a taboo around suicide, helping people who want to kill themselves open a dialogue and seek help. About 70% of people who get the green light from Dignitas for an assisted suicide never contact the group again, proving the palliative effect of knowing help is available, he says. "
...
"A vote is planned in March on a bill that would sharply restrict the activities of right-to-die organizations. For instance, two doctors must testify that a person is terminally ill, thus ruling out assistance for the chronically or mentally ill. The person seeking help must have given long consideration to his wish to die before doctors can prescribe lethal drugs. Moreover, right-to-die groups would be barred from accepting payments beyond those covering the costs of the suicide. The government also tabled a second bill that would ban assisted suicides altogether. "

The debate has taken a dramatic turn, beginning with a BBC narrator stating on air “I killed someone once.”
The Prime Minister has weighed in too: Gordon Brown: don't legalise assisted suicide.

Economics job market scramble

If you are a new economics Ph.D. and the market is going slowly, hang in there. Similarly if you are a department or other employer who is still trying to fill a position. There's still lots of action left in the market.

If you are still on the market near the end of March, you should think about registering for the 2010 Job Market Scramble

Important Dates:
March 23: Registration will Open
March 30: Registration will Close
April 1-12: Scramble Website will open for viewing by registered participants only
April 12: Scramble Viewing will Close

See the Scramble Guide for more detailed information.

Brief Description:
Occasionally prospective employers of new Ph.D. economists exhaust their candidates before hiring someone during the winter/spring "job market" period. Similarly, new economics Ph.D.s seeking a job sometimes find that all of the prospective employers with whom they have interviewed have hired someone else before they have secured an appointment.
To address these problems, the AEA has established a "Job Market Scramble" web site to facilitate communication between employers and job seekers in late spring. In March, employers that continue to have an open position previously listed in Job Openings for Economists (JOE) may post a short notice of its availability (with a link to the JOE listing). Similarly, new or recent economics Ph.D. job seekers still looking for a position may post a short announcement of their continued availability, with a link to their application materials (C.V., papers, references). The web site will open for viewing to those who have listed a position or availability soon after listings close. There is no charge for the "Job Market Scramble."

In each of the last four years between 67 and 100 employers have participated in the scramble, and (despite low response rates to the post scramble survey of participants) the AEA's Ad Hoc Committee on the Job Market (which I chair) has been able to confirm that more than 10% of the jobs offered through the scramble have been filled through contacts initiated via the scramble.

The market for cooked food (and thoughts of D'Artagnan at Maastricht)

The market for pleasure boats ranges from canoes to yachts, and air transport ranges from economy class to big private jets, but the market for cooked food must rival them in its range. Here's an account of an enterprise yacht/jumbo jet meal: The D’Artagnan Anniversary Party.

"To mark the 25th anniversary of her company, D’Artagnan, Ariane Daguin, a native of the Gascon region in the southwest of France, flew in over two hundred of her countrymen for a week-long celebration in New York. ... What’s more, throughout the week Ms. Daugin installed a handful of Michelin-starred Gascon chefs in some of the most venerated kitchens in the city. The collaborations between the visiting chefs and their hosts culminated last Sunday in what D’Artagnan billed as, “The 32 Star Dinner: A Progressive Dining Experience.” Thirty-two is the total number of Michelin and New York Times stars achieved by the group of chefs responsible for the meal, which, true to the epicurean spirit of the evening, was served not in one restaurant, but in four: cocktails, hors d’oeuvres, and the first two courses at Daniel, the next at Jean-Georges, two more at Per Se, and dessert at Le Bernardin. The buses that chauffeured us from stop to stop were filled with Gascon Armagnac."

(The headline of the article had led me to think it might be about the historical D'Artagnan, whose experience of Maastricht, in 1673, was more unfortunate than mine in 2009:)

Living Liver and Kidney Donation

The American Journal of Transplantation has assembled a "virtual issue" of articles they have published on various aspects of live donation, including kidney exchange. It seems to be ungated.

Living Liver and Kidney Donation

Guest Editor: Dr. Jonathan Bromberg
"This virtual issue of the American Journal of Transplantation is focused on living donation. For practical purposes, the articles are restricted to only liver and kidney donation. It would not be an overstatement to say that donation has probably been the number one issue to dominate the field for the last decade, as organ quality and availability determine all activities in transplantation. The breadth of importance and ramifications of donation are reflected in the wide variety of articles and topics that cover this area of interest. Novel sources of donors, such as altruistic, anonymous, and non-directed donation among others are covered in the first section. While considered even unusual a few years ago, many of these sources are now firmly partly of the mainstream of living donation. Exchanges, swaps, chains, and dominos are included in the second section, reflecting the evolution of the field as ever more complex donor and recipient algorithms are implemented, and their attendant ramifications on quality, cost, and outcomes. The third section covers organ utilization and outcomes, with an emphasis on matching the optimal donor with the correct recipient, and comparing deceased to living donor organs. The fourth section covers regulatory issues at the national and local levels, and their influence on donation and outcomes. The fifth section comprises issues relating to the donor and donor safety. The work-up process, safeguards, operative techniques, short term outcomes, and very long term outcomes are major issues the have dominated recent trends. The sixth and last section covers educational issues as they related to donor and family knowledge and attitudes toward donation, and that affects donation rates. These reports should provide the reader with a comprehensive view of issues in living liver and kidney donation, and the diverse paths taken that have moved the field forward."

Herb Scarf explains mathematical economics

Herb Scarf (who certainly knows) explains what is mathematical economics to a Humanities audience. His powerpoint slides for that talk are here, along with videos of some other talks (that I wasn't able to download, however).

His examples include matching of medical residents, school choice, and kidney exchange.

The Future of Same Sex Marriage

The University of San Francisco Law Review's Spring Symposium, held today, is on The Future of Same-Sex Marriage.

I like the sound of the first panel discussion, called
Crunching the Numbers: Examining empirical data regarding the material consequences of denying or recognizing same-sex marriage.

Stability may be hard to achieve in decentralized matching

So says a paper by Muriel Niederle and Leeat Yariv: Decentralized Matching with Aligned Preferences

Abstract. We study a simple model of a decentralized market game in which firms make directed offers to workers. We focus on markets in which agents have aligned preferences. When agents have complete information or when there are no frictions in
the economy, there exists an equilibrium that yields the stable match. In the presence of market frictions and preference uncertainty, harsher assumptions on the richness of the economy have to be made in order for decentralized markets to generate stable outcomes in equilibrium.

Compatible pairs in kidney exchange

The question of whether compatible patient-donor pairs should be invited to take part in kidney exchange is gaining some exposure with recent articles and news items in the medical literature. The issue is that if kidney exchange is restricted to patients who are incompatible with their live donors, we will be seeing many fewer blood type O donors than are in the general population, so exchanges will be more difficult to find, and there will be fewer transplants than if there weren't such a shortage. (Since O donors don't have a blood type incompatibility with any recipient, most of them will be compatible with their intended recipients; O donors are only incompatible if there is some other, immunological incompatibility.)

Here's a story from the most recent, Feb 2010 Nephrology Times: Dramatic Increase in Transplant Rates Projected if Compatible Pairs Are Included in Kidney Swaps

It follows up on a recent article by Lloyd Ratner, of Columbia University/New York–Presbyterian Hospital, reporting such a three-way exchange (Transplantation, 2010;89:15-22). The story also interviews some of the other pioneering surgeons involved in kidney exchange, including Frank Delmonico, Bob Montgomery and Steve Woodle.

Inviting compatible pairs to participate in exchanges seems like a very good idea indeed. (An early discussion, with simulations to provide quantitative estimates of the effect of including compatible pairs (which is quite large), was reported in Table 1 of:
Roth, Alvin E., Tayfun Sonmez, and M. Utku Unver, "A Kidney Exchange Clearinghouse in New England" American Economic Review, Papers and Proceedings, 95,2, May, 2005, 376-380. )

Market design at Yahoo!

Here's a project description from Yahoo! Research: Microeconomics and Market Design
By Michael Schwarz and David Reiley


What are the effects of complexity in mechanism design? Participating in an auction mechanism (or any market institution) requires time and effort on the side of the buyers. That in turn may lead some buyers to bid very conservatively, or not to participate at all, in order to economize on effort. We lack a theory for quantifying the complexity of a mechanism.


Auction theory and matching theory offer models and algorithms for allocating goods or matching market participants. However, the majority of markets do not use structured mechanisms (such as auctions and matching algorithms). Why are some markets (such the medical residency match) using centralized matching procedure while other markets (such as the purchases of automobiles with various options packages) do not? Answering this question may help to design structured market mechanisms for the markets where chaotic negotiations rule the day.

Understanding when and how reputations emerge, and how to improve the designs of structured reputation systems. Reputations of individuals and businesses play an important role in economic and personal life. With some exceptions, most notably in electronic commerce, the mechanisms for accumulating reputation are informal rather than structured.

How should a firm set posted prices for a menu of products? Although economics offers a theoretical framework for how to set prices, most theory assumes omniscience about demand. To build a practical pricing engine, one needs a system that generates exogenous price variation and then uses it to calculate appropriate prices going forward. Yahoo! offers thousands, even millions, of different advertising products, so estimating a demand system suffers from the curse of dimensionality as well as practical constraints (perceived fairness, etc.) in generating price variation. We are looking for better theory and econometrics for the problem of building a pricing engine.

Choosing schools (in NYC and SF)

I've written elswhere about the school choice process for public schools in San Francisco and for high schools in New York City. But, regardless of whether the process is a good one or not, the problem facing parents who have to decide how much they like each school can be a tough one, especially if there are a lot of schools.

Two articles help you feel the pain:

New Plan on School Selection, but Still Discontent discusses San Francisco, and
It’s a nightmare to apply for high schools in city discusses New York.

Some more background information here.

Determining death for deceased organ donation

Darshak Sanghavi, writing a while ago in the NY Times Sunday Magazine, discusses When Does Death Start?

"Organ transplantation must abide by the so-called dead-donor rule: a person has to be declared dead before any vital organs can be removed. Yet organs have to be alive if there is any hope of successful transfer to a recipient. Medical professionals have handled this paradoxical situation — finding a dead body with live organs — by fashioning a category of people with beating hearts who are said to be brain-dead, usually after a traumatic head injury, and who are considered just as dead as if they had rigor mortis.
To diagnose brain death, doctors typically go through a checklist of about a dozen items, including assessing reflexes like blinking, coughing and breathing, which are all controlled by the brainstem. The criteria are extremely strict, and only a tiny fraction of severely brain-injured people meet them."

Before brain death, the traditional definition of death involved irreversible cessation of heart beat, and you can also donate after cardiac death (DCD), but things have to move fast, since once circulation stops the organs begin to die. "D.C.D. requires doctors to confront the shadowy question of exactly when somebody dies after the heart stops."

In the U.S., we seem to be converging on a 5-minute rule.

Kim Krawiec on selling virginity

Kim Krawiec has a post commenting on recent news stories and linking to a new paper: Like A Virgin? We Sell That Here!

"A few days ago, an anonymous 19-year-old New Zealand student offered her virginity to the highest bidder on the Web site http://www.ineed.co.nz/ under the name "Unigirl," saying she would use the money to pay for her tuition. According to Unigirl, more than 30,000 people have viewed her ad and over 1,200 made bids before she accepted a $32,000 offer. Story from NPR. (HT: Tonja Jacobi)
Though the story is creating a ruckus, including international press, the attention pales in comparison to that bestowed on the very similar story of “Natalie Dylan,” a pseudonym adopted by a 22-year old UC San Diego graduate who auctioned her virginity on the website of the Moonlight Bunny Ranch, a Carson City brothel, in January of 2009 in order to foot the bill for graduate research in women’s studies. In contrast to Unigirl’s paltry returns, Dylan reportedly received over 10,000 bids, the highest of which was $3.8 million, receiving both condemnation and praise in the auction process. Critics have argued that she is degrading herself and women generally, risks exporting Nevada’s poor morals to the rest of the country, and is selling something (virginity) for profit that should be cherished and freely given.
In an article I posted to SSRN over the weekend, A Woman’s Worth, I consider the reactions to Dylan’s virginity auction plan and the possible motivations underlying those reactions. What drives the attention and controversy generated by the Dylan auction? What are the perceived harms associated with Dylan’s actions, and in what ways are they greater than the harms associated with similar common activities? "

And here's the abstract to her paper on SSRN:

A Woman's Worth
Kimberly D. Krawiec Duke University - School of LawFebruary 6, 2010 North Carolina Law Review, Forthcoming

Abstract: This Article examines three traditionally “taboo trades”: (1) the sale of sex, (2) compensated egg donation, and (3) commercial surrogacy. The article purposely invokes examples in which the compensated provision of goods or services (primarily or exclusively by women) is legal, but in which commodification is only partially achieved or is constrained in some way. I argue that incomplete commodification disadvantages female providers in these instances, by constraining their agency, earning power, and status. Moreover, anticommodification and coercion rhetoric is sometimes invoked in these settings by interest groups who, at best, have little interest in female empowerment and, at worst, have economic or political interests at odds with it.
