Fishing as an endangered but protected transaction

Here in New England, the plight of the fishing industry, and particularly of independent fishermen who operate small "day boats" from local harbors, is in the news. Three issues compete for attention: how to sustainably manage vulnerable fish populations, while keeping fishing profitable, particularly for the small independent fishermen who are seen as needing protection from larger, corporate fishing fleets.  Small fishermen are to New England what small family farms are in other areas of the country.

Here's a story from the Globe.

Change in fishing rules altering storied industry: Regulators to look at ways to protect fleet
"PLYMOUTH — Scores of fishermen have stopped going to sea in the past year as controversial new rules take hold that could fundamentally alter the storied fishing economy, culture, and communities of New England.

"The region’s scenic harbors already shelter hundreds fewer fishing boats than a decade ago, but some worry that smaller boats may vanish altogether: There are some signs the new rules, which assign groups of fishermen a quota on their catch of cod and other bottom-hugging fish, could accelerate a trend of consolidating those boats into far fewer, more efficient vessels. Some small-boat fishermen are selling or leasing their allotment to others under the new rules because they cannot turn a profit.

"“This may not be the end of fishing, but it is the end of fishing as we know it,’’ said Steve Welch, as he tinkered on one of his two boats, the Holly & Abby, in Plymouth. Nearby, his dog Hudson ate mussels that seagulls dropped on an icy dock.
Welch leased the fishing privileges on both his boats and laid off three workers this year. “We are talking jobs, tradition, culture,’’ he said. “All that will be left are large boats owned by corporations with deep pockets.’’ 
...
"However, it is inevitable, Grant said, that some fishermen will be pushed out of business for good because there are still not enough fish for all the fishermen. And that is a hard thing to take.
Fishing is not what [these fishermen] do; it is who they are,’’ Grant said. “It helps define the community. You can’t say that about selling tires. They are a cultural icon.’’
...
"Still, there are some bright spots with the new rules. Some $5 million in federal funds has been allotted to New England states to buy fishing permits and lease them back, often at a reduced price, to vulnerable fishermen. Some fishermen say the new rules are successful, allowing them to keep catching bottom-dwelling fish while others are diversifying to go after more abundant species.
But some fishermen, like Welch, wonder whether there will be small fishermen left when the fish finally come back.
I’ve been fishing for 33 years,’’ Welch said, proudly pointing out how he overhauled the electrical and hydraulic system on the Holly & Abby. “I’m a small, independent business owner. That should have value.’’"

SBE 2020: Future Research in the Social, Behavioral & Economic Sciences

The NSF has made available all 244 papers received in response to its request SBE 2020: Future Research in the Social, Behavioral & Economic Sciences


I earlier blogged about the  subset of 48 Economics "Grand Challenge" white papers posted by the American Economic Association, which includes some related to market design.

The market for used books

There have always been markets for used books, and it's one of the markets that has been most changed by the internet. I recently received an email that seems to indicate another change, this one aimed at increasing the supply of used books. The email was from Amazon.com, and the subject line referred to a book I bought a few months ago: "Sell Back "36 Arguments for the Existence of God: A Work of Fiction"

The message went on to say
Dear Amazon.com Customer,

Customers who purchased textbooks from Amazon.com may be interested in an easy way to get great prices for used titles through our Textbook Buyback Store.

Unraveling of pathology fellowships

A forthcoming paper in the journal Human Pathology gives a detailed account of the unraveling of the market for Pathology subspecialty fellowships, including the now familiar path towards earlier offers more diffuse in time, and to the increased hiring of internal candidates. It's an unusually thorough report that details some of the special pathologies of the Pathology labor market, and also compares it to the experience of other subspecialties such as Gastroenterology.

"Unlike the application process for first-year Pathology Residency, which is run through the National Resident MatchingProgram, applications for Subspecialty Pathology Fellowships are not coordinated by any consistent schedule. Competition for Subspecialty Pathology Fellowships has consistently resulted in undesirable drift of the fellowship application process to dates that are unacceptably early for many fellowship applicants. Responding to widespread dissatisfaction voiced by national pathology resident organizations, in 2007, the Association of Pathology Chairs began evaluation and potential intervention in the fellowship application process. Three years of intermittently intense discussion, surveys, and market analysis, have led the Council of the Association of Pathology Chairs to recommend implementation of a Pathology Subspecialty Fellowship Matching program starting in the 2011 to 2012 recruiting year, for those Applicants matriculating in fellowship programs July 2013. We report on the data that informed this decision and discuss the pros and cons that are so keenly felt by the stakeholders in this as-yet-incomplete reform process."

That's from the abstract of

"Pathology subspecialty fellowship application reform 2007 to 2010" by James M. Crawford MD, PhD,  Robert D. Hoffman MD, PhD, W. Stephen Black-Schaffer MD, in Human Pathology (2010)

Sales by museums

The NY Times reports on a Philadelphia museum's sales of parts of its collection to finance renovations, and on the controversy this has caused: Museum Sells Pieces of Its Past, Reviving a Debate

"A galloping horse weather vane sold for about $20,000, and the cigar store Indians brought in more than $1 million. A Thomas Sully oil painting of Andrew Jackson netted $80,500, and a still life by Raphaelle Peale, part of the family that put portraiture in this city on the map, was auctioned at Christie’s for $842,500.

"These were just a few of more than 2,000 items quietly sold by the Philadelphia History Museum over the last several years, all part of an effort to cull its collection of 100,000 artifacts and raise money for a $5.8 million renovation of its 1826 building.

In doing so the museum stepped into the quicksand of murky rules, guidelines and ethical strictures meant to discourage museums everywhere from selling collections to pay bills. It is one of the hottest issues in the museum world today. With budgets shrinking in a bad economy, the pressure to generate revenue is growing along with fears that museums are squandering public trusts meant to preserve the artifacts of the past for future generations.

The National Academy Museum in New York, Fisk University and Brandeis have all recently drawn fire — and even sanctions — for selling or planning to sell artworks, and none of them sold as many works as the museum here.

"In general art and objects are supposed to be sold only to finance acquisitions, though different museums are governed by different standards. Art museums, regulated by a formal code of the Association of Art Museum Directors, may not sell work for any other reason.

"As a history museum, though, this institution — formally called the Philadelphia History Museum at the Atwater Kent — is subject to separate, less stringent guidelines put forward by other associations. So museum officials say the installation of new carpet, paint and lighting were all legitimate expenses to be paid from the proceeds under the guidelines of the  American Association of Museums, which say that sales can be used for the “direct care” of a collection. Adding to the confusion, there is a third set of standards maintained by theAmerican Association for State and Local History permitting proceeds to go toward the “preservation” of a collection, a similarly broad term.

"The New York State legislature, confronting this maze of precepts, recently considered passing a law that would make selling collections — the art world term is deaccessioning — to pay operating expenses illegal. It never made it to the Assembly floor because museums opposed it."

And here's another story about a librarian who submitted her resignation over deaccessioning: Small Town, Big Word, Major Issue
"Deaccessioning is the kind of word that makes eyes glaze over and can seem to be the preserve of dusty intellectuals and large museums. But it’s just a fancy name for the sale or giving away of art and artifacts by museums and other cultural organizations, and the dust-up here in this city of about 5,000 demonstrates that such debates occur in all kinds of places, big and small, where people feel protective about materials in their care.
With her personal gesture of protest in late September, Ms. Phillips stepped into a growing public controversy surrounding institutions that have sold or considered selling parts of their collections, which have been entrusted to them for the public’s benefit. Some say such sales can compromise collections, and others argue that museums, libraries and historical societies have to cull their collections periodically, particularly if there is pressure to pay their bills.
In Little Falls, library officials said they were selling things to raise money, not to cover operating costs, which institutions try to avoid, but to preserve other artifacts.
“We don’t have the space to take care of some of these items,” said Chester P. Szymanski III, the library’s president. “We’re not a museum. We’re a library.”

Kidney transplantation in Canada

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

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.
