Kidney exchange: Further utilization of donors via listed exchange

College of Administrative Science and Economics, Koç University, Sarıyer, İstanbul, 34450, Turkey

Abstract

There is a set of incompatible patient–donor pairs and these pairs are matched pairwise. A match between two pairs corresponds to a paired kidney donation, where pairs exchange donated kidneys, or a paired listed exchange, where the first donor donates a kidney to the deceased donor wait-list, the first patient receives the kidney of the second donor, and the second patient receives a priority on the wait-list. We characterize the set of exchanges with the maximum number of transplants from the set of pairs. This characterization generalizes the well-known Gallai–Edmonds Decomposition Theorem.

Near Feasible Stable Matchings with Complementarities, by Nguyen and Vohra

Here's an interesting new paper on couples in matching markets. When couples are present, the set of stable matchings may be empty, but a "small" perturbation of the problem that increases the capacities of some employers and decreases the capacity of others, restores the existence of stable matchings.  (I haven't yet fully absorbed this, e.g. its impact on overall employment...)

Boot camps for new software developers

Tamar Lewin in the NY Times has the story on a new kind of educational institution, designed to quickly produce software developers: Web-Era Trade Schools, Feeding a Need for Code

"SAN FRANCISCO — A new educational institution, the coding boot camp, is quietly emerging as the vocational school for the digital age, devoted to creating software developers.
These boot camps reflect the start-up ethic: small for-profit enterprises that are fast (classes are two to four months), nimble (revising curriculum to meet industry needs) and unconcerned with SAT scores or diplomas. Most are expensive, but some accept a share of the graduates’ first-year earnings or a finder’s fee from employers as payment.
Most important, at a time when so many young people are underemployed, most graduates, especially those from highly selective boot camps, quickly find well-paying jobs. In a recent survey of 48 boot camps, Course Report, an online boot camp directory, found that three-quarters of graduates were employed, with raises averaging 44 percent from their pre-boot camp pay and an average salary of $76,000."

Congratulations to Jean Tirole

Hearty congratulations to Jean Tirole, who won the 2014 Nobel Prize in Economics.

Or did he win The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, or perhaps the Nobel Memorial Prize in Economics?


Here are some data, from Google Ngrams...



And here's Shakespeare on the subject:
"What’s in a name? that which we call a rose
By any other name would smell as sweet"

Congratulations again, Jean, on a well deserved award, whatever it's called.

Helping low income students with college applications


David Leonhardt in the NY Times recently wrote about ‘A National Admissions Office’ for Low-Income Strivers, about a nonprofit company called Questbridge.

He writes that it "has quietly become one of the biggest players in elite-college admissions. Almost 300 undergraduates at Stanford this year, or 4 percent of the student body, came through QuestBridge. The share at Amherst is 11 percent, and it’s 9 percent at Pomona. At Yale, the admissions office has changed its application to make it more like QuestBridge’s."
...
"QuestBridge has figured out how to convince thousands of high-achieving, low-income students that they really can attend a top college. “It’s like a national admissions office,” said Catharine Bond Hill, the president of Vassar.
...
"College admissions officers attribute the organization’s success to the simplicity of its approach to students. It avoids mind-numbingly complex talk of financial-aid forms and formulas that scare away so many low-income families (and frustrate so many middle-income families, like my own when I was applying to college). QuestBridge instead gives students a simple message: If you get in, you can go.
...
The group’s founders, Michael and Ana Rowena McCullough, are now turning their attention to the estimated $3 billion in outside scholarships, from local Rotary Clubs, corporations and other groups, that are awarded every year to high school seniors. The McCulloughs see this money as a wasted opportunity, saying it comes too late to affect whether and where students go to college. It doesn’t help the many high-achieving, low-income strivers who don’t apply to top colleges — and often don’t graduate from any college.

“Any private scholarship given at the end of senior year is intrinsically disconnected from the college application process,” Dr. McCullough said, “and it doesn’t have to be.”

They plan to offer prizes in some cases to high school juniors, like a summer program or a free laptop, to persuade them to apply. To win the prize, the junior would need to fill out a detailed application, which could become the basis for his or her college application. The idea draws on social science research, which has shown that people often respond better to tangible, short-term incentives (a free laptop) than to complicated, longer-term ones (a college degree, which will improve your life and which you can afford). Two pilot programs started with donors — one focused on New Yorkers, one on low-income Jewish students — have had encouraging results, the McCulloughs say.
...
"It has an early application deadline, in late September, and a long application form, designed to get students to tell the story of their lives.

"Crucially, the program promises a scholarship not just for one year but for four. As Mrs. McCullough, the organization’s chief executive, said, “Unless you make that kind of promise to the students and their parents, they’re going to worry, ‘Will the schools really pay for all four years?’ ”
...
"The winners of the scholarships — which colleges pay for, as they do for much of QuestBridge’s budget — go through a matching process. They attend their first choice among any of the 35 participating colleges that admit them. Hundreds of scholarship finalists who don’t win are admitted separately to the colleges, through a more typical admissions process, often with nearly full scholarships. The students form a support network for one another, they say."
...
"As much as QuestBridge has grown, it of course remains tiny relative to the population of college-ready, low-income teenagers. Only a small slice of them will attend colleges with the resources to offer full scholarships. That’s why the larger lessons of QuestBridge are so important.

"What are they? One, the complexity of the financial-aid process is scaring students away from college. “You don’t even know what it’s talking about half the time,” Mr. Parker said of the federal form. The Obama administration has taken steps to simplify it, but a full revamping would require help from Congress.

"Two, large amounts of well-meaning scholarship money — from private sources as well as from Washington and state governments — is fairly ineffectual. It helps many students who would graduate from college regardless, rather than those with the skills to graduate who are at risk of not doing so.

"Three, not every problem created by inequality is fiendishly difficult to solve.

"Yes, many of them are, from growing gaps in health and family structure to struggling public K-12 schools. Yet some gritty teenagers, like Ms. Trickey and Mr. Slate, still figure out a way to emerge from high school with stunning résumés. They’re on track to become quintessentially American success stories — and far too many of them still end up falling short."

Market design at Stanford, Fall 2014 (current course materials)

The URL of the Stanford course on market design that I'm teaching with Muriel Niederle this quarter is too long to fit into the heading of this blog, but here it is if you'd like to see our class materials, which are the slides presented so far:
https://coursework.stanford.edu/portal/site/F14-ECON-285-01 


F14-ECON-285-01 - Matching and Market Design

Course Information
Term:FALL 2014
Instructor(s):Muriel Niederle, Alvin Roth
Long Description

F14-ECON-285-01 This is an introduction to market design, intended mainly for second year PhD students in economics (but also open to other graduates students from around the university and to undergrads who have taken undergrad market design). It will emphasize the combined use of economic theory, experiments and empirical analysis to analyze and engineer market rules and institutions. In this first quarter we will pay particular attention to matching markets, which are those in which price doesn't do all of the work, and which include some kind of application or selection process. In recent years market designers have participated in the design and implementation of a number of marketplaces, and the course will emphasize the relation between theory and practice, for example in the design of labor market clearinghouses for American doctors, and school choice programs in a growing number of American cities (including New York and Boston), and the allocation of organs for transplantation. Various forms of market failure will also be discussed. Assignment: One final paper. The objective of the final paper is to study an existing market or an environment with a potential role for a market, describe the relevant market design questions, and evaluate how the current market design works and/or propose improvements on the current design.


Update: I hadn't realized that you need a Stanford login to get to the course page, and I haven't figured out a way around that...:(
