The NSF celebrates kidney exchange

Over at Science Nation, the NSF  published a short news article yesterday, together with a video, to  note the success of NSF funded research in helping establish kidney exchange (also called kidney paired donation, KPD).

Here's the article:
New Software Matches More Kidney Donations, Faster: Game theory and market dynamics inspire new software that streamlines complicated matches

"With support from the National Science Foundation (NSF), Harvard University economist Alvin Roth helped develop a suite of computer programs that match living kidney donors with recipients. His team includes market designer Itai Ashlagi and operations researcher David Gamarnik at MIT and economists Utku Unver and Tayfun Sonmez at Boston College."
...
"Transplant surgeon Michael Rees at the University of Toledo Medical center is CEO of the Alliance for Paired Donation (see www.paireddonation.org) [says]
..."game theory and market design have come together to find practical solutions for kidney disease patients."

 And here's the 2-minute video:
(Key question in the video, read in an incredulous tone: "What's an economist doing organizing kidney transplants?" Answer: "Turns out, an understanding of game theory and market dynamics is key...")

Market design for radio spectrum: new NSF program

Here's an   announcement that recently went out from the National Science Foundation:

"Dear Colleagues,

"I am writing to you today because of a just published NSF solicitation with the title “Enhancing Access to the Radio Spectrum (EARS)” [and a submission deadline of June 14, 2012]. The complete solicitation can be found here: http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=503480 .

"The synopsis reads:

“The National Science Foundation's Directorates for Mathematical and Physical Sciences (MPS), Engineering (ENG), Computer and Information Science and Engineering (CISE), and Social, Behavioral, and Economic Sciences (SBE) are coordinating efforts to identify bold new concepts with the potential to contribute to significant improvements in the efficiency of radio spectrum utilization, and in the ability for traditionally underserved Americans to benefit from current and future wireless-enabled goods and services. EARS seeks to fund innovative collaborative research that transcends the traditional boundaries of existing programs, such as research that spans disciplines covered by two or more of the participating NSF directorates.”

"A number of economists participated in an EARS Workshop here at the NSF in 2010. The final workshop-report can be found at: http://www.nsf.gov/mps/ast/nsf_ears_workshop_2010_final_report.pdf .

"It is my hope that you could spread the word among potentially interested social scientists who may want to submit an interdisciplinary proposal that has social science as its central component.

"According to the solicitation:

“The key research areas of interest to the EARS program include, but are not limited to, those that impact a wide range of technologies, applications, and users. Some broad examples and general topic areas include, but are not limited to:”

...

-       " Security of wireless signals and systems in the context of spectrum sharing.

-        ...

-      " Economic models for spectrum resource sharing. There exists a need for interdisciplinary research in the areas of market and non-market-based mechanisms for spectrum access and usage to efficiently organize the sharing of scarce spectrum resources. Examples of research themes include, but are not limited to, real-time auctions, market design, spectrum valuation, spectrum management for the home user and managing mixed-rights spectrum.

-        New and novel measurement-based spectrum management techniques, including agent-based systems, policy-based spectrum management, local and scalable spectrum management.”

"I would be thankful if you could forward information about the solicitation to other potentially interested researcher.

"Please feel free to send us any suggestions you may have to ensure that Social, Behavioral and Economic Sciences will be prominently represented among the EARS proposal submissions."

What does the NSF do? What should it do? Reports from and about the Social, Behavioral and Economic Sciences, and Dec 1 Webinar

What should the National Science Foundation division of Social, Behavioral and Economic Sciences be doing? They asked and we answered, and now they're having a webinar to report the results: here's the email announcement.

Dear Colleague:

Just a year ago, we stopped accepting SBE 2020 white papers.  The papers were released to the public in February and now we have completed a report, Rebuilding the Mosaic, which briefly describes the process, some of the themes we identified, and the programmatic implications of what we learned.  The report is available at: http://www.nsf.gov/sbe/sbe_2020/index.cfm, and we expect to host a webinar/town hall on December 1.  The login details are below.

All of your papers contributed to our thinking about the future of research in the SBE sciences, and we continue to be amazed at and grateful for your participation.  I hope that you will take a moment to read the report – all of the papers are listed in Appendix 5.  For the foreseeable future, we also expect to maintain the website (http://www.nsf.gov/sbe/sbe_2020/index.cfm), where the papers can be individually found and downloaded, since the report cannot substitute for the many ideas that you have shared with us and with the American people.

Although I have written to you before to express my appreciation, one more time, let me say:

Thank you.

Earlier, in a statement to Congress, Dr. Gutmann highlighted some of the tangible benefits derived from market design work that the NSF has supported:

Statement of
Dr. Myron P. Gutmann,
Assistant Director, Social, Behavioral, and Economic Sciences 
National Science Foundation

Before the Committee on Science, Space, and Technology Subcommittee on Research and Science EducationUnited States House of Representatives

"3.1 SBE research has resulted in measurable gains for the U.S. taxpayer

Matching markets and kidney transplants. Researchers in economics at Harvard University, the University of Pittsburgh, and Boston College have applied economic matching theory to develop a system that dramatically improves the ability of doctors to find compatible kidneys for patients on transplant lists. Organ donation is an example of an exchange that relies on mutual convergence of need. In this case, a donor and a recipient. This system allows matches to take place in a string of exchanges, shortening the waiting time and, in the case of organ transplants, potentially saving thousands of lives.¹⁰ Similar matching markets exist in other contexts, for example, for assigning doctors to residencies.

Spectrum auctions. Spectrum auctions have generated $54 billion for the U.S. Treasury between 1994 and 2007 and worldwide revenues in excess of $200 billion. Researchers at Stanford University and the California Institute of Technology, supported by grants from SBE, developed the simultaneous ascending auction mechanism as a technique for auctioning off multiple goods whose values are not fixed but depend on each other. The mechanism was then tested experimentally and further refined before being implemented by the Federal Communications Commission. In this auction, all of the goods are on the selling block at the same time, and open for bids by any bidder. By giving bidders real-time information on the tentative price at each bid stage, bidders can develop a sense for where prices are likely to head and adjust their bids to get the package of goods they want. This process enables "price discovery," helping bidders to determine the values of all possible packages of goods. These auctions not only raise money, but ensure efficient allocation of spectra so that the winners of the auction are indeed the individuals who value the spectra the most. Applied with great benefit for the U.S. taxpayer in the FCC spectrum auctions, this method has also been extended to the sale of divisible goods in electricity, gas, and environmental markets.^11"

Here's an earlier post on congressional testimony:

NSF Social, Behavioral and Economic Sciences--attack and defense

NSF Social, Behavioral and Economic Sciences--attack and defense

As budget talks go on in Washington, the Social, Behavioral and Economic Sciences division of the National Science Foundation has become a specific focus of discussion (as distinguished from support for other science funded by NSF). The Consortium of Social Science Associations posts a number of documents, including Talking Points, which highlights some of the economics research funded by NSF over the years, including several research streams in market design (e.g. spectrum auctions and kidney exchange).

"According to the Consortium of Social Science Associations (COSSA), amendments will probably be offered to disproportionately cut or completely eliminate funding for the National Science Foundation's Social, Behavioral, and Economic (SBE) Sciences Directorate when NSF's 2012 appropriations are voted on by the House.
...
"Amendments to cut NSF/SBE funding are most likely to be submitted when the spending bill comes to the House floor in the first week of August.

"We are calling this to your attention now because there might not be enough time for AEA members to express their opinions once the amendment is proposed and before it is voted on. Economists of all people understand the need to take action to deal with the U.S. fiscal challenge. But these amendments might target the social sciences for disproportionate funding reductions and possibly elimination. Economic research has profound value for society and we want to make sure that this is understood by policymakers. Although the NSF budget for the social and behavioral sciences is small (in FY2010 $255 million out of a total NSF budget of $7 billion), eliminating it would have very negative consequences for economic research and economic policy.

"The following are some reasons why Republicans and Democrats both should oppose this amendment:
• Unique Role: NSF’s SBE Directorate is the only place in the Federal government with a broad mandate to maintain and strengthen the basic science of economics. It provides over one-half of all external support by the Federal government for basic research in economics. SBE’s Economics Program current budget is only $26.5 million. Although other government agencies, private foundations and the private sector support applied and some basic economics research, none have the resources and the incentives to support the new methods, data and broad range of substantive research funded by NSF. Severe cuts in an already small NSF budget for economics would be a major blow to the infrastructure needed to support the best research on extremely complex and important economic questions.

• Very High Return on Past Investments: Since 1994 spectrum auctions have generated more than $50 billion for the U.S. Treasury and worldwide revenues in excess of $200 billion. Researchers at Stanford University and the California Institute of Technology, supported by grants from NSF, developed the simultaneous ascending auction mechanism as a technique for auctioning off multiple goods whose values are not fixed but depend on each other. The mechanism was then tested experimentally in a laboratory, also financed by NSF, before its implementation by the Federal Communications Commission. These auctions not only benefit the US taxpayer, but ensure efficient allocation of spectra so that the winners of the auction are indeed the individuals who value the spectra the most. This method has also been extended to the sale of divisible goods in electricity, gas, and environmental markets.

• Innovation and Adoption of New Technologies: SBE funded a number of awards that have resulted in fundamental advances in our understanding of the economic factors that encourage innovation and the adoption of new technologies. For example, Nicholas Bloom at Stanford University was awarded a Faculty Early CAREER Development award for his research into the role innovation plays in determining economic productivity and growth. This research includes developing new data collection methods for measuring management practices and adoption of information technology (IT) in business. Using an innovative double-blind survey, he has been able to gather systematic evidence about the effects of specific management practices on the success and failure of firms. His research also has shed new light on the links between increased use of IT and patterns of international trade between the US and less developed countries. Other
work supported by SBE contributes to our understanding of how uncertainty shocks affect decisions made by businesses that in turn contribute to macroeconomic fluctuations.

• Lives Saved: Researchers in economics at Harvard University, the University of Pittsburgh, and Boston College have applied economic matching theory to develop a system that dramatically improves the ability of doctors to find compatible kidneys for patients on transplant lists. Organ donation is an example of an exchange that relies on mutual convergence of need; in this case, a donor and a recipient. This system allows matches to take place in a string of exchanges, shortening the waiting time and, in the case of organ transplants, potentially saving thousands of lives. Similar matching markets exist in other contexts, for example, for assigning doctors to residencies or students to schools.


• Millions Lifted out of Poverty: Microfinance has spread very rapidly in the last decade, raising the hope that it has the power to lift millions out of poverty by providing them with access to capital. Loans are often given to groups of five to ten women who are jointly liable for the loan to the group. Basic research findings from SBE grants have led to important practical advice for microfinance practitioners. SBE grantee Esther Duflo was named by TIME magazine one of the 100 most influential people in the world in 2011 for her work this area.

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.

Economics "Grand Challenge" white papers

The American Economic Association has published what appears to be the full set of 'white papers' in Economics submitted to the NSF in reply to their earlier request:

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"

NSF "Grand Challenge" white paper on market design

The National Science Foundation has asked for two-thousand-word 'white papers' on challenges worth exploring over the next decade.

Here's mine, on Market Design.

Abstract

In the past fifteen years, the emerging field of Market Design has solved important practical problems, and clarified both what we know and what we don’t yet know about how markets work. The challenge is to understand complex markets well enough to fix them when they’re broken, and implement new markets and market-like mechanisms when needed.

Among markets that economists have helped design are multi-unit auctions for complementary goods such as spectrum licenses; computerized clearinghouses such as the National Resident Matching Program, through which most American doctors get their first jobs; decentralized labor markets such as those for more advanced medical positions and for academic positions; school choice systems; and kidney exchange, which allows patients with incompatible living donors to exchange donor kidneys with other incompatible patient-donor pairs.

These markets differ from markets for simple commodities, in which, once prices have been established, everyone can choose whatever they can afford. Most of these markets are matching markets, in which you can’t just choose what you want, you also have to be chosen. One of the scientific challenges is to learn more about the workings of complex matching markets, such as labor markets for professionals, college admissions, and marriage.

Dual career couples

Although dual career couples in academia aren't strictly speaking (only) a gender concern, the best collection of resources on academic couples I've found is on a site organized through an NSF program for the advancement of women in science and engineering careers.

It consists of links to reports both on what academic couples do, and on what universities do (or should do) to accomodate them and hire them.  One Stanford report, called Dual-Career Academic Couples: What Universities Need to Know surveyed full time faculty at 13 research universities and found that 36% had partners employed in academia. (And of course many other professors are part of two-professional-career households even if their partner isn't an academic.)

So this is a big and growing issue for the academic labor market, likely to play out in different hiring policies, and employment patters for urban and rural universities.

There are obviously some market design issues, as well as strategy issues. For example, there are now legal restrictions on what you can ask a potential employee about her/his marital status. But academic couples also have to decide to what extent to do joint searches that involve/inform the potential employers at an early stage.

The AAUP has just released a set of Recommendations on Partner Accommodation and Dual Career Appointments (2010). Here's an accompanying story from Inside Higher Ed, which outlines some of the contradictory impulses behind the AAUP recommendations (which suggest both that partner hires should not be as adjuncts, nor should they come at the expense of adjunct positions): Doing 'Dual Career' Right.

Here are my earlier posts on couples, including discussion of how the couples match plays out for medical residents (and a link to a recent paper).

Congressional briefing, postscript

On March 15, 2010 I gave a 15 minute presentation as part of a Congressional Briefing on the usefulness of Economics (particularly economic research supported by the NSF). Here are my slides: Improved Markets for Doctors, Organ Transplants and School Choice. (My talk focused on how early NSF-supported game theory research had led to recent developments in market design.)

The slides take a little while to load, since they contain a few photos. Speaking of photos, afterwards there were some photo opportunities, and I was happy to be included in the one above with my new Senator from MA, Scott Brown, who I wish the very best of luck in his demanding new job.

Mentoring (and a pet peeve: maybe women should be athena-ed?)

There are lots of reasons to think that young employees of many kinds may benefit from mentoring, and, because networks of various sorts may be important, employees from underrepresented populations may particularly benefit if their mentor can help them connect.

This is the idea behind the recent NBER report Can Mentoring Help Female Assistant Professors? Interim Results from a Randomized Trial
by Francine D. Blau, Janet M. Currie, Rachel T.A. Croson, Donna K. Ginther

Abstract: "While much has been written about the potential benefits of mentoring in academia, very little research documents its effectiveness. We present data from a randomized controlled trial of a mentoring program for female economists organized by the Committee for the Status of Women in the Economics Profession and sponsored by the National Science Foundation and the American Economics Association. To our knowledge, this is the first randomized trial of a mentoring program in academia. We evaluate the performance of three cohorts of participants and randomly-assigned controls from 2004, 2006, and 2008. This paper presents an interim assessment of the program’s effects. Our results suggest that mentoring works. After five years the 2004 treatment group averaged .4 more NSF or NIH grants and 3 additional publications, and were 25 percentage points more likely to have a top-tier publication. There are significant but smaller effects at three years post-treatment for the 2004 and 2006 cohorts combined. While it is too early to assess the ultimate effects of mentoring on the academic careers of program participants, the results suggest that this type of mentoring may be one way to help women advance in the Economics profession and, by extension, in other male-dominated academic fields. "

On a less serious note, I've always wondered whether "mentor" was the right word for an advisor for female professors, particularly if the advisor is also female. The reason is that Mentor is a male character in Homer's Odyssey who only appears to give advice in the beginning of the story. In fact, the goddess Athena is giving the advice, disguised as Mentor (presumably because advice from someone with a grey beard was given more weight in those days than from someone advising while female, however divine). So maybe, nowadays, female professors should be athena-ed?

A LEAP forward at Harvard

Here is an email announcement I received today from my colleague Raj Chetty:

I am writing to introduce the Lab for Economic Applications and Policy
(LEAP) at Harvard. The mission of LEAP is facilitate policy-relevant applied research, with the ultimate aim of injecting scientific evidence into policy debates.

LEAP has three components. First, we fund faculty and student research, such as pilot field experiments or empirical studies that could not be easily or quickly funded through the NSF or other grant agencies. The LEAP executive committee (Larry Katz, Guido Imbens, Brigitte Madrian, and myself) will review applications on a rolling basis and authorize funding within 4-6 weeks. The application form is available at our temporary website:
http://economics.harvard.edu/leap. Please spread the word about these new funding opportunities among your graduate students.

Second, we run a visitor program that brings in two leading researchers every semester to visit the department and teach short topics courses related to their research. This year’s visitors are Jon Skinner, Stephen Coate, Doug Staiger, and Richard Blundell.

Finally, we have a cluster of offices on the 2nd floor of Littauer that includes a lounge to facilitate interaction among faculty and students.
This space includes visitor offices as well as a rotating office used by junior faculty at HKS and HBS. We plan to hold a small inaugural reception in the lounge at 3:15 on Wed Feb. 10 before the labor/pf seminar, and invite you to join us then to learn more about LEAP.

We look forward to working with you at LEAP!

NSF survey of earned doctorates

The NSF reports on doctoral degrees granted by American universities: National Science Foundation, Division of Science Resources Statistics. 2009. Doctorate Recipients from U.S. Universities: Summary Report 2007–08. Special Report NSF 10-309. Arlington, VA. Available at http://www.nsf.gov/statistics/nsf10309/.

The number of earned doctorates in Economics went from 800 in 1978 (when 27% were to women) to 1091 in 2008 (when 34% were to women).
