A new report, Treatment of End-Stage Organ Failure in Canada; 2000 to 2009 draws on data from CIHI's Canadian Organ Replacement Register (CORR). (The report can be accessed directly here.) A news report focusing on kidney transplantation is here: Kidney transplants can save millions in dialysis costs: organ transplant report.
From the news summary:
"The number of people living with kidney failure more than tripled in Canada in the last 20 years, new statistics show, but experts hope to save lives and millions of dollars in dialysis costs by expanding organ donor programs.
"A report released Thursday by the Canadian Institute for Health Information shows that at the end of 2009, there were 37,744 people being treated for end-stage renal disease, with 59 per cent of them on dialysis and 41 per cent living with a functioning kidney transplant.
"Kidney failure rates appear to be stabilizing, but the supply of organs available for transplant has not kept pace with growing demand.
About 3,000 people were on waiting lists for a transplant in 2009. If they all received a transplant, it could result in annual savings of $150 million, the institute estimated.
...
"As for transplants, Nickerson said deceased donation tends to be better than average in Quebec and Atlantic Canada, at between 16 and 19 donors per million population.
"If you look at the U.S., the average donation rate is around 26 to 28 donors per million; if you look at Spain, it's up in the 30 donors per million range," Nickerson said.
"Donation rates can be significantly higher than what they are currently in Canada. And we've been stuck at this sort of 14 to 15 national average for a number of years now."
...
"CIHI estimated the annual cost of hemodialysis treatment at $60,000 per patient, compared to a one-time cost of $23,000 for a transplant plus $6,000 per year for medication.
Nickerson said savings are about $250,000 over five years.
"Sixteen to 20 years is the average expectancy of a living donor kidney transplant," he said, adding that deceased donor transplants would probably last 10 to 12 years.
Between 2000 and 2009, there were 10,641 kidney transplant procedures registered in the Canadian Organ Replacement Registry. Of these, 11 per cent were re-transplants. Of the 9,430 kidney-only first transplants, 61 per cent used deceased donor kidneys.
Since 2006, the number of living donor kidney transplants has been stable, fluctuating between 440 and 461 transplants per year.
...
"Canadian Blood Services recently launched a paired kidney exchange registry, which allows pairs to receive and donate a kidney from among other registered pairs even if they're not matches for each other.
Nickerson said 185 pairs are registered, and 65 kidney transplants have been done that otherwise wouldn't have occurred.
"And we know that this is only the beginning," he said.
"We estimate that we should have on an annual basis another 200 to 250 pairs joining annually and that we can facilitate about half of them finding transplants on a yearly basis."

Swiss parliament proposes to decriminalize incest
Switzerland considers repealing incest laws
"The upper house of the Swiss parliament has drafted a law decriminalising sex between consenting family members which must now be considered by the government.
"There have been only three cases of incest since 1984.
"...children within families will continue to be protected by laws governing abuse and paedophilia.
"Daniel Vischer, a Green party MP, said he saw nothing wrong with two consenting adults having sex, even if they were related.
"Incest is a difficult moral question, but not one that is answered by penal law," he said.
"Barbara Schmid Federer of The Christian People's Party of Switzerland said the proposal from the upper house was "completely repugnant."
"I for one could not countenance painting out such a law from the statute books."
The Protestant People's Party is also opposed to decriminalising the offence which at present carries a maximum three year jail term.
A spokesman for the party said: "Murder is also quite rare in Switzerland but no one suggests that we remove that as an office from the statutes."

Homophobia: gay sex remains a repugnant transaction for many
If a repugnant transaction is one that some people want to engage in and others don't want them to, then sex is surely the most ancient. Some of this comes from the desire to control procreation (and be able to identify the father of each child), but that doesn't account for the repugnance of homosexual sex.
Elsewhere I've posted how this ancient repugnance seems to be crumbling, as same sex marriage slowly becomes legal in more places (and as the U.S. armed services have been slowly pushed to more clearly welcome the service of gay soldiers). But two recent articles make the point that homosexual sex is still a widely repugnant transaction.
Gays in Africa face growing persecution, human rights activists say
"In Uganda, a bill introduced in parliament last year would impose the death penalty for repeated same-sex relations and life imprisonment for other homosexual acts. Local newspapers are outing gays, potentially inciting the public to attack them, activists say."
"In Uganda, we look at homosexuality as an abomination. It is not normal," said Nsaba Butoro, Uganda's minister on ethics and integrity and a vocal supporter of the bill. "You are talking about a clash of cultures. The question is: Which culture is superior, the African one or the Western one?"
"More than two-thirds of African countries have laws criminalizing homosexuality. In May, a judge in Malawi imposed a maximum prison sentence of 14 years with hard labor on a gay couple convicted of "unnatural acts" for holding an engagement ceremony. Malawi's president pardoned the couple after international condemnation, particularly from Britain, Malawi's largest donor.
"Gays have also been attacked this year in Zimbabwe, and in Senegal their graves have been desecrated. Gays in Cameroon have been attacked by police and targeted in the media. In Gambia, President Yahya Jammeh has vowed to expel gays from the country and urged citizens not to rent homes to them.
"One exception is South Africa, whose constitution was the first in the world to outlaw discrimination based on sexual orientation and is among a few countries in the world that have legalized same-sex marriages."
And here's an article closer to home: Gay Bashing at the Smithsonian, about an artwork removed from the exhibit by the National Portrait Gallery recently.

European carbon markets suspended
The suspension of trading on European carbon emissions markets has been covered fairly widely, with the most interesting (and critical) story I've seen being this one from the Telegraph. European carbon market suspended over fraud fears: "The European carbon market has been thrown into turmoil after the scandal-hit scheme was suspended for a week over suspicions of fraud."
"More than €2bn (£1.7bn) of trade is likely to be disrupted after the European Commission said it would prevent transactions until January 26.
"The suspension follows allegations that 475,000 carbon credits worth €7m were stolen in a hacking attack on the Czech carbon register. It appears that the intangible allowances were bounced between eastern European countries before disappearing without a trace."
...
"This is not the first challenge to the credibility of the €90bn annual market in carbon allowances
"Under the flagship scheme, companies need permits to emit carbon dioxide as part of the global fight against climate change and polluters are granted a certain number of emissions allowances that can be traded.
"But it has been plagued by fraud, with Europol estimating that carbon trading criminals trying to play the system may have accounted for up to 90pc of all market activity in some European countries during 2009. Fraudulent traders mainly from Britain, France, Spain, Denmark and Holland pocketed an estimated €5bn. Carbon allowances are particularly susceptible to fraud because they are high value, intangible and easily moved between different countries."

Kidney chains in India, and a millionaire nondirected donor
Kidney chains are coming to India, and one of the first (maybe the first) non-directed donors is a millionaire businessman: Kidney donation chain bank set up in Trichur
"19 January 2011 TRIVANDRUM — A leading industrialist in Kerala has set into motion a novel kidney donation chain by deciding to donate one of his kidneys to a stranger.
"Kochouseph Chittilapally, owner of V-Guard group of companies, signed the papers to donate his kidney to 48-year-old Joy from Palai on the occasion of the launch of a kidney bank at Trichur on Monday.
"The bank was set up by the Kidney Federation of India (KFI), founded by Fr Davis Chiramel, who had shown the way by donating one of his kidneys to a stranger one-and-half-years ago. The kidney chain — the first of its kind in India — is possible because of a new type of organ donation called a paired donation, in which a person who needs a kidney can get one by bringing up a donor.
"Joy became eligible to get the kidney after his wife, Jolly, agreed to donate her kidney to one Shamsuddin. His wife, Sainaba, will give her kidney to one John, and whose mother in turn will donate her kidney to Baiju.
"The chain ended here as Baiju could not get a donor among his close relatives. Fr Chiramel is not disappointed. He said he will be able to launch another chain shortly as there were people willing to donate their kidneys. “I was flooded with calls after the kidney bank was launched. Out of 150 callers I had till Tuesday afternoon, 10 were willing to donate their kidneys. We will get them medically examined and put them in the chain if they are fit to donate their kidneys,” the priest said."

Barter in a recession
In a Tight Holiday Season, Some Turn to Barter
"The proliferation of Web sites with names like Swap.com and SwapMamas have moved swaps from the home and the community center to online bazaars with millions of users. No industry figures exist on the number of for-profit startups, but officials at one of the largest, Swap.com, said they have over a million registered users and an inventory of 15 million items at any given time.
"ThredUP opened business in April as a clothing exchange site and expanded this month to toys. Mrs. Spitzer signed up as a member in August.
She said that she used to buy new clothes for her three children, all under age 7, every couple of months and then give them away as her children outgrew them. But after she joined ThredUP, she began viewing her children’s hand-me-downs as currency."
Swap.com and ThredUP charge a small fee for each trade ($1 and $5). I didn't see such a fee on SwapMamas, which also encourages people to offer their used goods as gifts when they don't find a coincidence of wants, and has a reputation system that is intended to make frequent givers also favored recipients of gifts.

Greg Lewis' market design course at Harvard
My colleague Greg Lewis will be teaching a market design course this semester, and sends this email:
"I just wanted to advertise the market design course I'm teaching this semester (Econ 2056b). The syllabus can be found here. It's designed to be a complement to both Al and Peter's class (Econ 2056) and Ariel's IO class (Econ 2610), and it's a mix of theory and structural empirical techniques.
I've mixed up the style of the course a bit from past years: from pretty much the second week on, we'll be alternating between lecture and discussion --- which means the students will have to work a little harder and participate more, and hopefully get more out in the end.
Hope to see you there!
Cheers
Greg"

Economics job market in Europe
The big marketplace for new Ph.D. economists is the one that takes place in North America each year in early January (see this recent paper), but in recent years the Royal Economic Society has attempted to get one going in Europe.
The 6th PhD Presentation Meeting of the Royal Economic Society is going on this weekend, on Saturday 15th and Sunday 16th January 2011 at City University London.
"The aim of the event is to provide a service both for UK and European university economics departments wishing to recruit lecturers, and for PhD students seeking academic jobs in the UK or elsewhere in Europe. This annual meeting has grown to be an extremely successful event, well supported by both students and potential employers. The event consists of two days of students’ presentations and poster sessions. Participating institutions (pdf) attend these presentations and are also allocated a room at the conference site in order to arrange individual appointments with participating PhD candidates (pdf) during the course of the conference. "
Good luck to all those on the market.
(For departments interested in the theory of matching, I notice that one of the new Ph.D.s in attendance is Alex Nichifor, who is a coauthor of a very good paper: Stability and Competitive Equilibrium in Trading Networks . (His coauthors are John Hatfield, Scott Kominers, Mike Ostrovsky, and Alex Westkamp, and his Ph.D. advisor is Bettina Klaus.))

Tribal customs of academic disciplines
Some of the different ways that different academic disciplines organize their scholarship, and the signals they send about it, are discussed in a recent column in the Chronicle of Higher Education about tenure reviews.
"A fair analysis of a tenure candidate requires that the committee members know (or learn) about the culture of the relevant academic discipline, particularly with respect to norms of publication numbers, venues, authorship order, conference presentations, invited talks, and student or postdoctoral advising.
"Considerable variation in those features exists across academe, even within science and engineering fields. Whereas one academic discipline might value short publications in highly selective conference proceedings over peer-reviewed journal articles, another requires peer-reviewed journal articles (in high-impact journals) as the primary indicator of productivity. Similarly, one discipline might alphabetize author order, another always has the "brains behind the project" as the last author, and another considers the first author listed to be the most important. Some fields expect assistant professors to have advised one or more Ph.D. students through to the completion of their degree, but in other fields that would be considered unusual."
The different customs of publication order present some opportunities in interdisciplinary collaborations of the kind that arise in market design, particularly since the authors publishing outside of their disciplinary journals are freed from the burden of sending signals.

In France, civil unions aren't just for same sex couples
A pacte civil de solidarité in France is a civil union, something like a civil marriage, originally intended to help same-sex couples formalize their relationship, without expanding the official scope of marriage. But these civil unions are easier to dissolve than formal marriages, and (the NY Times reports), opposite sex couples are also finding this less formal kind of union attractive: In France, Civil Unions Gain Favor Over Marriage
"French couples are increasingly shunning traditional marriages and opting instead for civil unions, to the point that there are now two civil unions for every three marriages.
"When France created its system of civil unions in 1999, it was heralded as a revolution in gay rights, a relationship almost like marriage, but not quite. No one, though, anticipated how many couples would make use of the new law. Nor was it predicted that by 2009, the overwhelming majority of civil unions would be between straight couples.
"It remains unclear whether the idea of a civil union, called a pacte civil de solidarité, or PACS, has responded to a shift in social attitudes or caused one. But it has proved remarkably well suited to France and its particularities about marriage, divorce, religion and taxes — and it can be dissolved with just a registered letter."
Meanwhile, in Britain, which also has civil partnerships, a lawsuit is underway to change the fact that both same sex marriage and different sex civil partnerships are illegal:
"Eight British couples will argue that the twin bans on same-sex marriages and heterosexual civil partnerships are unlawful and should be reversed.

"Over the last two months four homosexual couples have all been refused marriage licenses at register offices across England, while four heterosexual couples were turned away when they applied for civil partnership status.
"The couples will file a joint application to the court today, which is the fifth anniversary of the first civil partnership ceremonies in England."

Pictures from a matching conference (and a new matching paper)
I returned from Milan to the following cheerful message from Atila Abdulkadiroglu:
Dear all,
I hope you have had a cheerful holiday season, happy new year to you all.
I thought it would be better late than never, so here are also some photos from the "Roth and Sotomayor: Twenty Years After" conference: http://duke.edu/~aa88/RothandSotomayorTwentyYearsAfter/
This is all of the photos I got from our media relations person, I hope she got all of us at least in the first photo.
I would also like bring your attention a recent paper of mine:
"Generalized Matching for School Choice" ( http://duke.edu/~aa88/articles/GeneralizedMatching.pdf )
This paper makes the case that neither a one-sided matching model nor a two-sided matching model is adequate enough to capture some salient features of the school choice problem. It introduces a natural generalization to the matching models, and a natural extension of the stability notion. It characterizes student optimal stable matchings and introduces a new matching algorithm, Stable Transfer Cycles, that reduces to TTC when the problem is one-sided and becomes equivalent to Gale-Shapley's student optimal stable matching mechanism when the problem is two-sided.
Comments would be most welcome."

Specialized dating sites for the disabled
Searching for a mate is hard work, and it can be hard to find a match if you have special needs. So there's a demand for specialized dating sites: Difference Is the Norm on These Dating Sites
"Several dating Web sites for singles with health problems have started up in the last few years. Ms. Nevius joined Dating 4 Disabled, a site for people with an array of disabilities, including paralysis and multiple sclerosis. Other sites include NoLongerLonely, for adults with mental illness, and POZ Personals, for people who are H.I.V-positive."
...
"He said the worst part of dating was the anxiety over disclosing his H.I.V. status. Getting to know someone in an online community of people with H.I.V. allows relationships to form without the burden of the big reveal hovering overhead.
“Here everyone knows you have H.I.V.,” he said, “so it gets that barrier out of the way.”
"Another site, Prescription4Love, has communities dedicated to sexually transmitted diseases and physical disabilities, but also to other diseases that don’t conjure images of romance and intimacy, like diabetes and Parkinson’s. The site was created by Ricky Durham, whose late brother suffered from Crohn’s disease — a condition that came with literal baggage.
“He was a good-looking boy,” Mr. Durham said. “But when do you tell a girl that you have a colostomy bag? The first date? The third? There’s no good time.”
"Awkward issues that come with an illness can be discussed frankly and openly in an online space in which everyone is dealing with something out of the ordinary.
“Sexuality, travel, mobility, pain: Everything takes on a different dimension,” said Merryl Kaplan, who is in charge of member services for Dating 4 Disabled.
"The anonymity of the Internet allows people to be forthcoming and honest about what they are truly looking for in a companion. Among the almost 12,000 members of Dating 4 Disabled, for example, many specify the types of disabilities they would be open to dealing with in a long-term relationship.
“Like anyone else, people with disabilities have different preferences,” Ms. Kaplan said. “Someone with good mobility may prefer someone also mobile; others don’t limit at all.”
"Several dating Web sites for singles with health problems have started up in the last few years. Ms. Nevius joined Dating 4 Disabled, a site for people with an array of disabilities, including paralysis and multiple sclerosis. Other sites include NoLongerLonely, for adults with mental illness, and POZ Personals, for people who are H.I.V-positive."

"He said the worst part of dating was the anxiety over disclosing his H.I.V. status. Getting to know someone in an online community of people with H.I.V. allows relationships to form without the burden of the big reveal hovering overhead.
“Here everyone knows you have H.I.V.,” he said, “so it gets that barrier out of the way.”

Tips, Tip Pooling, and Tip Credits
Restaurant wait-staff in the United States make a significant part of their incomes in tips left by satisfied or habit-driven or social-norm-conscious patrons (but this isn't a post about the large behavioral literature on restaurant tipping, e.g. here). A consequence of this is that restaurants and certain other employers can receive "tip credits" that release them from the obligation to pay the minimum wage, since their employees will be having part of their wage paid by their customers.
There's a body of law about what employers can and cannot do with tips (e.g. require them to be pooled, shared with non wait-staff, etc.), and about what constitutes a tip (e.g. not all "service charges" go to the server): see e.g. NoLo.com's Tips, Tip Pooling, and Tip Credits: What Service Employees Need to Know
There are presently a number of lawsuits going through the courts about this, and some new legislation, discussed in an op-ed in the NY Times by Tim and Nina Zagat of Zagat's fame: Adding Fairness to the Tip
With the new year have come some new regulations in NY: New Rules Impose Systems for Sharing of Tips
"The new regulations apply to workers in restaurants and hotels and cover a number of issues, including who should pay for laundering “wash-and-wear” uniforms, like special T-shirts. The rules also raise the minimum wage for tipped employees, to $5 from $4.65 an hour for food service workers and to $5.65 from $4.90 an hour for service workers, a category that includes coat check workers in a restaurant or porters in hotels. (There is a separate minimum for workers at resort hotels.)
"The new rules also define the job categories that are eligible for shares in tips from the dining room: food service workers only, including waiters, bartenders and bussers, as well as sommeliers and hosts, provided they are not managers.
"The new rules allow restaurants to dictate both the system and the percentage allocated to each job category. Gratuities can be combined in a pool, to be divided by all the staff members who have helped a team effort. Or, individual servers can collect their own tips and give portions, or shares, to members of the team.
"The Labor Department will require that employers keep records of tip pools and shares; the records could be examined during investigations undertaken by the department on its own or in response to complaints.
...
"Higher-end, full-service restaurants tend to favor the pooling of tips, because it breeds less squabbling over stations and shift assignments, provides an incentive for teamwork and encourages the servers to police their own performance.
"The new regulations generally limit the pool to service workers in the dining room who interact with customers directly — like waiters — or indirectly, like servers who ferry plates from the kitchen to a station where another server picks them up and delivers them to the table. But bartenders, who prepare beverages for the dining room in a role analogous to that of a cook, can also share in the tip pool, even though kitchen staff members cannot.
“A lot of this arises from custom and tradition,” Ms. Lindholm said. “If you’re looking for perfect logic in this, it isn’t there.”

Wikipedia fundraising, randomized experiments
You know those fundraising appeals that appear at the top of Wikipedia pages? They are randomized so that reliable information can be collected about which ones attract donations.
The Wikimedia team writes:
"Since August, the Fundraising Committee has been running banner & landing page tests. These have evolved from weekly Thursday afternoon tests, which helped us get all of our systems in order and determined which messages would best motivate our donors before the launch of the fundraiser - to almost daily tests introducing new banners and landing pages as we continue to tweak our current campaign.
"Check out the Fundraising Updates page where we discuss what we've learned so far and upcoming tests and challenges."

Slavery in the U.S.
At the conference I'm attending in Finland, there's been a good deal of discussion (with more to come) of repugnant transactions, with an undercurrent of concern that globalization and other kinds of encroachment of markets on traditionally non-market ways of allocating resources will inevitably cause things presently regarded with repugnance to become more customary.
It's good to remember that our repugnance at certain transactions doesn't have to diminish over time (as does happen with many formerly repugnant transactions like same sex marriage). Slavery (and indentured servitude, and other forms of servitude) were once regarded with much less repugnance--certainly much less nearly universal repugnance--than they are today.
The NY Times recently published a Civil War era map of where slaves were in the United States in 1860:
Visualizing Slavery
"South Carolina, which led the rebellion, was one of two states which enslaved a majority of its population, a fact starkly represented on the map."
