I am The Fixer in the IMF's Finance and Development magazine

The Fixer, it turns out, is the title of a profile of me, based on an interview, and on conversations with some of my old and not so old colleagues, published in the IMF's Finance and Development magazine.

(The title makes me think of the Malamud novel, which isn't bad when you recall that the fixer was a handyman...and which is a lot better than thinking of the corrupt politicians who could "fix" your speeding tickets... A handy man is a characterization worth trying to live up to, sort of like Keynes' dentists...)

Possibilities for kidney exchange in Mexico

Last week Mike Rees and I spoke at the Centro Medico ABC in Mexico City, to try to help them organize kidney exchange in Mexico.  I'm looking forward to seeing what develops...

Here is some media coverage in Spanish...I can't tell (from Google translate) how clearly various conversations are reported...since I don't speak Spanish, some interviews were also conducted through translators.

Shane Greenstein on a false history of email

Sometimes people believe that they deserve more credit than they're getting, and Shane Greenstein writes about a man who believes he should be credited with inventing email.  (Earlier this morning I mistakenly identified the author of the post as Shane's co-blogger Joshua Gans; apologies to both.) Apparently the fellow who thinks he invented email and should get the credit for it is pretty clearly mistaken, but the Huffington Post took the bait, and so Shane organizes his post about how that makes HuffPo a much less trustworthy news source than he had hoped. (Apparently some things on the internet just aren't true...)  HuffPo and the Loss of Trust

"Now for the detail: HuffPo published a multipart history of email that is historically inaccurate. Yes, you read correctly. More specifically, a few of the details are correct, but those are placed next to some misleading facts, and these are embedded in a certifiably very misleading historical narrative. The whole account cannot be trusted.
The account comes from one guy, Shiva Ayyadurai, who did some great programming as a teenager. He claims to have invented electronic mail in 1978 when he was fourteen. He might have done some clever programming, but electronic mail already existed by the time he did his thing. Independent invention happens all the time in technological history, and Shiva is but another example, except for one thing. He had his ideas a little later than others, and the other ideas ended up being more influential on subsequent developments. Shiva can proudly join the long list of geeky teenagers who had some great technical skills at a young age, did some cool stuff, and basically had little impact on anybody else.
Except that Shiva won’t let it go. This looks like nothing more than Shiva’s ego getting in the way of an unbiased view.
Look, it is extremely well established that the email systems in use today descended from a set of inventors who built on each other’s inventions. They did their work prior to 1978. For example, it is well documented that the “@” in every email first showed up in 1971. Ray Tomlinson invented that. Others thought it was a good idea, and built on top of the @. We all have been doing it ever since. Moreover, this is not ancient history. Tomlinson has even written about his experiences, and lots of people know him. This is easy to confirm.
Though Ayyadurai’s shenanigans were exposed a few years ago, he persists. In the HuffPo piece yet again he pushes the story in which his inventions played a central place in the history of electronic mail. This time he has a slick infographic telling his version of things, and he managed to get others to act as shills for his story. He also now accuses others of fostering a conspiracy against his views in order to protect their place in history and deny him his.As if. “A teenager invented electronic mail” might be a great headline, and it might sound like a great romantic tale, but this guy is delusional."
Shane focuses on trust in news sources, but I can't help sympathize a bit with the delusional guy.  I know of many cases in which someone feels, often with considerable justice, that they don't get the credit they deserve. That's part of the problem with apportioning credit, and it may be a near universal feeling. You can certainly witness it among academics, and probably also among top athletes who don't make it to the Olympic podium or the Hall of Fame, and maybe even among some of those who do. Maybe a good sanity check on whether you are delusional is if you think there's a conspiracy...

David Warsh on Stanford Econ

David Warsh, in his role as economist-watcher, in The Providence Journal today (along with some observations about the market for newspapers):


"The Stanford University buildup in economics, financed by the riches of Silicon Valley, continues apace. Susan Athey and Guido Imbens, of Harvard, a married couple, last week accepted an offer. Previously announced was the decision of Alvin Roth, of Harvard Business School, to relocate to Palo Alto. Other offers are said to be in the works.


"Athey and Roth are market designers, at the forefront of especially exciting developments in present-day economics, in which the nexus with technology is especially germain. (Imbens is a highly rated econometrician.) Athey started a research laboratory for Microsoft in Cambridge that has since grown to considerable size. I don't suppose that the leadership of economics itself is in any danger of tipping out of Massachusetts. But it's clearly easier to make things happen on the Left Coast."

Paywalls create conflict of interest between newspapers and journalists

Journalists, like academics, want their writing to be read. Newspapers, like academic publishers, like to be paid for what they sell. Journalists, like academics like to make their papers available on the web. A recent email from the editor of the Boston Globe Ideas Section makes this clear:

"As you may know, this fall the Globe launched a spiffy new web site devoted exclusively to the newspaper. You may also have noticed it means Ideas is now behind a paywall. However, we have a "one click free" policy from any outside links -- and to provide you those links, and an easy way to keep up with Ideas, we've started a Boston Globe Ideas Facebook page. We also have a Twitter feed, @globeideas. Of course we'd love it if you subscribed to Bostonglobe.com -- but we're also making it easy for you to read and share Ideas stories for free by following one of our accounts."

Lending library for newspapers (help wanted ads, mostly)

Sonia Jaffe points me to this article: Renting a read from 'newspaper landlords'

"Garum Tesfaye is one of Addis Ababa's "newspaper landlords," a group of entrepreneurs in the Ethiopian capital who rent out papers to people too poor to buy them.
...
"For 20 to 30 minutes, these readers can get their hands on a newspaper for a fraction of the price of having to buy it. If they keep the paper longer than their allotted rental time, they have to pay extra.
"A newspaper in Addis Ababa costs about six birr (35 U.S. cents) to buy. In contrast, it costs only 50 Ethiopian cents (less than one U.S. cent) to rent one.
"If 20 readers read this single paper at the rate of 50 cents, I will make 10 birr (about 60 U.S. cents)," says Tesfaye, whose business serves a regular customer base that visits his makeshift roadside shop each day.
"Most of the readers focus on vacancies rather than regular news," Tesfaye says."

NSF ScienceLives interviews me on market design

The NSF writes about market design by interviewing me...
Economist Finds Best Matches for Students and Schools
By Ellen Ferrante, National Science Foundation

Some of the questions are about market design, and you'll have to click on the link above if you want to read my answers to those.  But some of the questions were designed to personalize science, and here are those, and my answers...

"What is the best piece of advice you ever received?
"There’s no limit to what a person can accomplish if he isn’t worried about who gets the credit. "

"What was your first scientific experiment as a child?
"I went to public school in NYC, and as I recall we had science fairs each year starting in grade school. The first projects I recall weren’t experiments; they were demonstrations, little bits of engineering. I remember that I built a carbon arc furnace out of boards, a flower pot, curtain rods and pieces of carbon from the core of a flashlight battery.

"What is your favorite thing about being a researcher?
"You can schedule your own mind. There are plenty of jobs in which a person has an opportunity to solve interesting problems, but a researcher, particularly an academic researcher, gets to choose which problems to work on.

"Who has had the most influence on your thinking as a researcher?
"I think my older brother Ted first persuaded me that science was exciting, and I learned a lot from my Ph.D. advisor at Stanford, Bob Wilson. Over the long term, the group of people from whom I’ve learned the most are my students and post-docs and co-investigators; I’ve been very fortunate in who I’ve been able to work with. "

"If you could only rescue one thing from your burning office or lab, what would it be?
"As often as not there’s a student or postdoc in my office. I’d rescue him or her. "

And here's the picture they ran, over the caption "Al Roth and Marilda Sotomayor photographed with their 1990 book “Two-Sided Matching,” at the conference Roth and Sotomayor: Twenty Years After, held at Duke University in May, 2010. Credit: Marilda Sotomayor"

The market for boasting

How did people boast signal before they had blogs?

Not long ago I was the subject of a flattering profile in Forbes (which I wrote about in this earlier blog boast post).
Yesterday I received a letter in the mail from a company that "specializes in turning articles into custom designed plaques."

It's not a bad idea, and if I were a restaurant, I'd buy one right away, and post it next to the menu, preferably where it could be read from the street.

Your penny for my two cents: micropayments on the web

Even if you are prepared to pay a penny for my thoughts, the transaction costs would likely deter you, unless the payment can be made automatically. This is the problem facing micropayments in particular, and it makes it hard for newspapers to charge for news.

Harvard's Neiman Journalism Lab reports on Google's marketplace proposal, which would allow customers to maintain a Google account that could be billed without requiring the customer to maintain accounts or reveal information to each content provider: Google developing a micropayment platform and pitching newspapers: “‘Open’ need not mean free”

Virginia Postrel on Kidney Exchange, and other (less distinguished) news coverage

Virginia Postrel's latest article in the Atlantic is about kidney exchange: ...With Functioning Kidneys for All.

She writes well (check out her Dynamist blog). In addition, as someone who gave one of her kidneys to a friend, she writes with a personal as well as a professional interest and authority. Her article mostly talks about kidney exchange as it is developing in the U.S., but also discusses possible donor compensation, and the international black market.

The article is well worth reading, and contains interesting links (including to this paper, in the New England Journal of Medicine, about a ten-transplant kidney chain, of which I'm happy to be among the coauthors).

It's a great thing to have kidney exchange covered in the press, because that allows more potential kidney exchange candidates to hear about the possibility, and it allows potential donors to know just how big an impact they could have. On this latter point, Postrel's article points out that
"Since the current transplant system extols altruism, one way to end the [long deceased donor waiting] list would be to find more altruists. With, say, 50,000 new living donors, deceased donation could easily pick up the slack. Again, the numbers aren’t that big. The Southern Baptist Convention includes 42,000 member churches; the United Methodist Church, whose Web site earlier this year featured the quote, “As United Methodists, we’re life savers,” counts more than 34,000 U.S. congregations. If each congregation produced just one new living donor, the waiting list would disappear. "

But press coverage is a bit puzzling. Not all of it is as careful and accurate and well reported as the Postrel article. (Which is not to say that even inaccurate coverage still isn't a good thing, for the way it spreads the news.) But I've been a little bemused at the way coverage sometimes simply follows press releases. Here's a story for those of you who find media an interesting subject.

Remember that NEJM article I mentioned above? It got a lot of press when it came out in March, maybe because the NEJM embargoes its articles until a day before publication, and that creates some buzz. That journal article reported a novel, non-simultaneous chain of transplants which begain in July 2007, in which 10 donors gave kidneys to 10 recipients, involving 6 transplant centers in 5 states. The innovative surgeon who was responsible for organizing that, Mike Rees, was the lead author of that article, and is the founder of the Alliance for Paired Donation. I thought the coverage was pretty accurate, perhaps because it was a news story that was about an article in a medical journal that the reporters could refer to.

But not all press releases are about peer-reviewed journal articles. This past week there have been a lot of stories about another remarkable accomplishment, another such chain, which accomplished 8 transplants, almost as many. It was organized out of Johns Hopkins, one of the leading hospitals doing kidney exchange in the U.S. It's not surprising that Hopkins surgeons should be among those pushing this kind of innovation forward; two of them who were involved in this new chain were among the coauthors of the NEJM article. And, while the accomplishment, so soon after the NEJM article, is noteworthy, the news coverage is in some ways as remarkable.

Here's the lead paragraph of the first of two stories about it in the Washington Post: "A Maryland transplant surgeon says he and doctors at four hospitals in four states have transplanted eight kidneys and he considers that the largest series of multi-kidney donations ever. "

The second Post story, the next day, repeats that claim (under the headline Successful Eight-Way Chain of Surgeries Involving Johns Hopkins Is a First:
"The first-of-its-kind surgery -- believed to be the largest chain of donations in history -- involved hospitals in four cities..."

The Post isn't alone. A few days later, after a chance to do some more in depth reporting and fact checking, the (July 11) CBS evening news reports on how one of the patients experienced "...a surprise rescue - the chance to be a part of the biggest multi-city, multi-patient domino kidney exchange ever."

There are three surprises for those interested in news reporting. First, the surgeon quoted above in the first Post story is one of the coauthors of the NEJM article about the earlier, larger chain, so that quote was an odd slip of the tongue (or, maybe he was misquoted, or maybe that's what's required to get kidney exchange the press coverage it deserves). Second, the AP and Post and CBS evening news reporters weren't aware of the earlier chain despite all the press coverage it received, including this (March 12) story (also) on the CBS Evening News about the earlier chain: A Transplant Surgeon Matches 10 Donors With Recipients In The Longest Chain In History .

But the third surprise is that there's a really great human interest story about this latest, Hopkins led chain. It's not just about the surgeons, it's also about the donors. One of the donors was a Hopkins hospital administrator, who had seen first hand the good that kidney donors can do, and wanted to help a friend, but turned out to be incompatible with that friend. That is just the kind of situation that kidney exchange was invented to help. (How do I know this? I read the Hopkins press release, which was headlined
Johns Hopkins leads first 16-patient, multicenter 'domino donor' kidney transplant.

The subheadline was "Johns Hopkins vice president 1 of the donors".

So, hats off to the Hopkins surgeons and their talented colleagues at Barnes-Jewish Hospital in St. Louis, INTEGRIS Baptist Medical Center in Oklahoma City and Henry Ford Hospital in Detroit. And a deep bow to the donors. As for the reporters, yours is a noble craft too; kidney exchange is complicated, keep trying.

(And thank you, Virginia, for your thoughtful story in the Atlantic.)

Market for information

Mostly we think it is good for information to be freely available, but one place where we often do not is in the adversarial system of trial by jury. The rules of evidence permit judges to decide what evidence is admissable, and what is not. I have served on juries in which we were instructed not to read news accounts of the trial we were part of. Sometimes juries are sequestered, so that they cannot have much contact with the outside world. That has all gotten a little harder to enforce, now that everyone has Google in their pocket: Mistrial by iPhone: Juries’ Web Research Upends Trials .

"Last week, a juror in a big federal drug trial in Florida admitted to the judge that he had been doing research on the case on the Internet, directly violating the judge’s instructions and centuries of legal rules. But when the judge questioned the rest of the jury, he got an even bigger shock.
Eight other jurors had been doing the same thing. The federal judge, William J. Zloch, had no choice but to declare a mistrial, wasting eight weeks of work by federal prosecutors and defense lawyers."

Science journals and science journalism

After my recent post The production of news: The NEJM news cycle about the effects of the New England Journal of Medicine's news embargo policy on the production of news stories, I corresponded with two of the young leaders in the new economics of media, Matt Gentzkow and Jesse Shapiro. They pointed out that, aside from increasing the number of stories, an embargo might increase their quality, by preventing a "race to the bottom" in which the shortest, least well reported stories can come out before more carefully researched stories. With an embargo, reporters don't have an incentive to rush to publish, they know they can work on their story up until the embargo expires.

A separate issue was raised in an article Matt pointed me to, one that I had already noticed sharply distinguishes scientific journals like the NEJM and Science, which publish short articles weekly, from journals like the ones economists normally publish in, which publish longer articles, much less frequently, and with much longer delay. In Ingelfinger, Embargoes, and Other Controls on the Dissemination of Science News, Vincent Kiernan explores not only the effect of embargos, but also of the "Ingelfinger rule" (named after a former NEJM editor), which is that NEJM, Science, etc. won't publish an article that has in any substantial way been made available before publication. So, in particular, papers appearing in those journals can't first be posted on the web as working papers.

This is in stark contrast to the way economists work; the usual practice these days for an economist who finishes a paper is to put it up on the web even before it has been submitted for publication. Economics journals function as the archival sources of papers, not as the place they are first distributed. And this predates the internet; economists have communicated via pre-publication working papers at least since I entered the business, after the invention of the printing press, but before the word processor.

Partly this difference has to do with the speed of publication. A paper accepted by Science or the NEJM will likely appear not too many months after it has been submitted, while the process at most economics journals takes well over a year (and two is not so unusual). As a result, the weekly science journals seek to be a combination of science journals and science news sources, in a way that economics journals do not.

The difference between the two was first brought home to me in 1990, when I received a call from the then editor of Science, which turned into a proposal that I write an article for them summarizing work I had done studying various labor markets for new doctors. I had circulated a working paper on that subject in 1989, and at the time of the phone call from Science it was forthcoming in the American Economic Review, in 1991. I told the editor of Science that I would have to check with the AER, but that if I wrote the article, it would state clearly that it was a summary of the longer AER article. He replied that he would like to have the article, provided the short summary in Science came out before the original article in the AER.

I called Orley Ashenfelter, who was then the editor of the AER, and he said something very close to "go ahead and give Science the summary, a five page paper can't scoop a twenty five page paper." His feeling was that as long as the AER had the definitive version, there was no problem. And that is how I came to have two papers on that subject, published out of order, in

Roth, A.E., "New Physicians: A Natural Experiment in Market Organization," Science, 250, 1990, 1524-1528.
and
Roth, A.E., "A Natural Experiment in the Organization of Entry Level Labor Markets: Regional Markets for New Physicians and Surgeons in the U.K.," American Economic Review, Vol. 81, June 1991, 415-440.

(These papers were posted to the web so long ago that they are html versions made from the original text files, rather than pdf versions of the actual publications.)

The production of news: The NEJM news cycle

My previous post was about the recent kidney exchange innovation by the Alliance for Paired Donation, just reported in today's issue of the New England Journal of Medicine. That NEJM immediately attracted some press, and in this post I consider the role that the NEJM's press embargo policy might play in generating news stories about some of the articles they publish.

The press policy of the NEJM is communicated to authors as follows (emphasis added):
"Your Brief Report will appear in the March 12, 2009 issue of the New England Journal of Medicine (NEJM). This information is confidential. There is a press embargo on the contents of the issue until 5:00 PM ET on Wednesday March 11, 2009. On Friday, March 6, 2009 the content of the March 12, 2009 issue will made available to reporters who have agreed to respect our embargo. "

That is, a week before publication, the NEJM makes the forthcoming issue available to reporters who have agreed not to write about it until a specified time the next week.

To better understand how this kind of policy plays out, I asked a public relations person about the NEJM and their policy, and got the following reply:
"...they have a reputation of being one of the best PR machines there is. Their embargo is one of the toughest on the planet as well; reporters and any others who violate it are dead for the rest of their lives in getting information on future NEJM articles. Anyone in the medical writing community knows and fears this."

At 9 pm on March 11, four hours after the embargo ended, here's what a Google news search for "kidney exchange" looked like (note the link to "all 217" news articles):

Kidney-transplant chain broadens donations
Boston Globe - ‎1 hour ago‎
Dr. Frank Delmonico of Massachusetts General Hospital, one of the architects of the New England Program for Kidney Exchange, disagreed. ...
New Computer Models Successfully Link Donors And Kidney Transplant ... Science Daily (press release)
Living Kidney Donation Chains May Help More Get Transplants U.S. News & World Report
Chain results in 10 kidney swaps among strangers The Associated Press
Pittsburgh Post Gazette
all 217 news articles »

The first of these articles, in the Globe, was written by a reporter who talked to several of the participants, concentrating on those in Boston (which is where the economists on the team all reside, and also where another kidney exchange program, the New England Program for Kidney Exchange was started). The second (in Science Daily) is a press release issued by Boston College (where my economist colleagues Tayfun Sonmez and Utku Unver both teach). Some of the remaining stories have original content, but many are largely if not completely taken from some of the original reporting and press material. (I like the story that ran in the Washington Post, because it has a slideshow that shows off Mike Rees, the innovative--and apparently good looking--surgeon who is the lead author of the NEJM article, and a figure of emerging importance in the national discussion of kidney exchange).

So...I've written a lot of articles that attract little or no press, and certainly not a flood in a few hours. While kidney exchange is undoubtedly a subject with wider popular appeal than, say, the lattice structure of fixed points, I'm guessing that the NEJM's embargo policy plays at least some role (recall the comment that they are one of the best PR machines...). Here are three hypotheses--one psychological and two economic--about why the embargo might matter.

Hypothesis 1 (behavioral/psychological): telling reporters they can't publish before 5PM Wednesday makes them want to write about the story more...

Hypothesis 2. (coordination equilibrium): telling reporters that no one can publish before 5PM Wednesday reassures them that the time they put into the story won't be wasted, they won't be scooped by someone else who finishes their story earlier.

Hypothesis 3. (common value/winner's curse): in the absence of an embargo, a reporter tempted to try to write the first story might be worried that the absence of previous stories means that the subject isn't as interesting as it looks, won't be picked by editors, etc. To put it another way, whoever writes the first story might be (like the high bidder in a common value auction) the person who thought it was the most interesting, and the fact that no one else agreed how interesting it was might mean that he has overestimated its value. But, when there is an embargo, this kind of negative selection can't be going on; no one else could have published earlier, so the absence of earlier stories isn't a negative signal.

(Blogs, incidentally, seem to work on a different schedule; here are the March 12 takes by Steve Levitt and by Tim Harford on the original story...)

Update: television works on a different schedule still: Mike Rees was interviewed later that evening (March 12) on the CBS Evening News: A Transplant Surgeon Matches 10 Donors With Recipients In The Longest Chain In History

Kidney Exchange

Miller-McCune magazine has an article on kidney exchange that gives a pretty good view of some current developments (having to do with exchanges involving compatible as well as incompatible pairs, and chains of transplants started by non-directed donors): Making a Market for Kidneys.

"Using game theory and market-design software, doctors are arranging kidney-transplant "swaps" — sometimes in long chains — to give more people with renal disease better transplant options and healthier futures."

The story mentions both the New England Program for Kidney Exchange, and the Alliance for Paired Donation, the two innovative kidney exchange networks with which Tayfun Sonmez, Utku Unver and I have worked extensively. (One of my longstanding frustrations with the ways in which stories make it into the news, however, is that, while I am mentioned by name in the story, my colleagues are not. I invariably mention this frustration to reporters when they call, but often it doesn't help. It must say something about the market for news, although I'm not quite sure what.
