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...:(

The brains of psychopaths (serial killers) and extraordinary altruists (nondirected kidney donors)

First, the altruists, in PNAS:
Neural and cognitive characteristics of extraordinary altruists
Abigail A. Marsha,1, Sarah A. Stoycosa, Kristin M. Brethel-Haurwitza, Paul Robinsonb, John W. VanMeterc, and Elise M. Cardinalea

Abstract: "Altruistic behavior improves the welfare of another individual while reducing the altruist’s welfare. Humans’ tendency to engage in altruistic behaviors is unevenly distributed across the population, and individual variation in altruistic tendencies may be genetically mediated. Although neural endophenotypes of heightened or extreme antisocial behavior tendencies have been identified in, for example, studies of psychopaths, little is known about the neural mechanisms that support heightened or extreme prosocial or altruistic tendencies. In this study, we used structural and functional magnetic resonance imaging to assess a population of extraordinary altruists: altruistic kidney donors who volunteered to donate a kidney to a stranger. Such donations meet the most stringent definitions of altruism in that they represent an intentional behavior that incurs significant costs to the donor to benefit an anonymous, nonkin other. Functional imaging and behavioral tasks included face-emotion processing paradigms that reliably distinguish psychopathic individuals from controls. Here we show that extraordinary altruists can be distinguished from controls by their enhanced volume in right amygdala and enhanced responsiveness of this structure to fearful facial expressions, an effect that predicts superior perceptual sensitivity to these expressions. These results mirror the reduced amygdala volume and reduced responsiveness to fearful facial expressions observed in psychopathic individuals. Our results support the possibility of a neural basis for extraordinary altruism. We anticipate that these findings will expand the scope of research on biological mechanisms that promote altruistic behaviors to include neural mechanisms that support affective and social responsiveness."


Here's a news story on the article: Who Would Donate a Kidney to a Stranger? An ‘Anti-Psychopath’
"In recent decades, psychopathy is something that’s captured the attention of both academics and the mainstream. Psychopaths play big roles in movies and even occasionally on public radio, and there’s evidence that a few of them may be in your company’s boardroom right this minute. 
But emerging research is changing how experts understand the condition. “There was a time when people thought of psychopaths as this sort of unique group of individuals — as in, there were normal people, and there were psychopaths,” said Georgetown University psychologist Abigail Marsh. “But now we’re finding that psychopathic traits work the same as other mental-illness symptoms. So with psychopathy, like almost anything else, people will have more or fewer of those traits, and so you have people at one end and most people in the middle.” Marsh calls this the “caring continuum,” and its existence, she said, “begs the question: What’s at the other end of the curve?”
New research she just published in Proceedings of the National Academy of Sciences suggests an answer: If the dark, scary end of the caring continuum is inhabited by psychopaths, way down at the other end is a group of what she calls “anti-psychopaths” — ultra-do-gooders who are extraordinarily compassionate, prosocial, and empathetic.
Marsh wanted to study the characteristics of these sorts of people, so she sought so-called “altruistic kidney donors” who offer up a kidney to anyone who needs it (as opposed to those who donate a kidney to a friend or loved one), figuring they would fit the bill."

Australian discussion of market design

For some reason, the public discussion of market design in business and government in Australia seems to hit a lot of the right notes, at least as superficially reported in the press. I don't always have the context to know what they are talking about, and whether I agree or disagree, but I like discussions that operate on the level of market design.

 For example, here's a story on the market for something they call vocational and educational training:
VET market ‘doesn’t work for everybody’: BCA’s Jennifer Westacott

"FAD-DRIVEN market reforms have left vocational education and training more disjointed than ever, according to two of the country’s biggest employer groups.

"Business Council of Australia chief executive Jennifer Westacottsaid that governments were pursuing contestable funding as “a policy vision in and of itself”, with no clear idea of why they were doing so.

We can’t just say let the market work, because it doesn’t always work for everybody — and I say that as the queen of capitalism,” Ms Westacott told the TAFE Directors Australia conference.

“It doesn’t often work for disadvantaged people, it doesn’t work in certain locations (and) it doesn’t work for emerging skills. Whenever you hear people say, ‘Let the market just run,’ you say: to what end and what purpose?

“Market reform has to be about outcomes, not fads.”

"Ms Westacott said she did not think it would ever be possible to establish a “completely free” market in VET. She said locational issues, low demand for some qualifications and special needs of some student groups would force governments to assert a degree of control.
...
"Ms Westacott acknowledged that market design was no simple task. “If this were easy, they’d do it,” she said."

Who prefers centralized to decentralized matching?

Here's a paper that looks at the question of centralized versus decentralized matching from an interesting angle:

 College Admissions with Entrance Exams: Centralized versus Decentralized
Isa E. Hafalir, Rustamdjan Hakimov, Dorothea Kübler, Morimitsu Kurino
September 2, 2014

Abstract: " We theoretically and experimentally study a college admissions problem in which colleges accept students by ranking students’ efforts in entrance exams. Students’ ability levels affect the cost of their efforts. We solve and compare equilibria of “centralized college admissions” (CCA) where students apply to all colleges, and “decentralized college admissions” (DCA)
where students only apply to one college. We show that lower ability students prefer DCA whereas higher ability students prefer CCA. The main predictions of the theory are supported by experiments, yet we find a number of differences that render DCA less attractive than CCA compared to equilibrium benchmark."

The paper begins with a description of some of the variety in college admissions around the world, before concentrating on the two extreme cases:

"In some countries, the application and admission process is centralized. For instance, in Turkey university assignment is solely determined by a national examination called YGS/LYS. After learning their scores, students can apply to a number of colleges. Applications are almost costless as all students need only to submit their rank-order of colleges to the central authority.1 On the other hand, Japan has a centralized “National Center test,” too, but all public universities including most prestigious universities require the candidate to take another, institution-specific secondary exam which takes place on the same day. This effectively prevents the students from applying to more than one public university.2 The admissions mechanism in Japan is decentralized, in the sense that colleges decide on their admissions independent of each other. In the United States, students take both centralized exams like the Scholastic Aptitude Test (SAT), and also complete college-specific requirements such as college admission essays. Students can apply to more than one college, but since the application process is costly, students typically send only a few applications (the majority being between two to six applications, see Chade, Lewis, and Smith, 2014). Hence, the United States college admissions mechanism falls in between the two extreme cases.

1. Greece, China, South Korea, and Taiwan have similar national exams that are the main criterion for the centralized mechanism of college admissions. In Hungary, the centralized admission mechanism is based on a score that combines grades from school with an entrance exam (Biro, 2012).
2. There are actually two stages where the structure of each stage is as explained in Section 4. The difference between the stages is that the capacities in the first stage are much greater than those in the second stage. Those who do not get admission to any college spend one year preparing for the next year’s exam. Moreover, the Japanese high school admissions authorities have adopted similar mechanisms in local districts. Although the mechanism adopted varies across prefectures and is changing year by year, its basic structure is that each student chooses one among a specified set of public schools and then takes an entrance exam at his or her chosen school. The exams are held on the same day. Finally, institution-specific exams that prevent students from applying to all colleges have also been used and debated in the United Kingdom, notably between the University of Cambridge and the University of Oxford. We thank Ken Binmore for pointing this out."

Medically assisted dying: debated in the NY Times

Here's the debate on medically assisted dying  in Tuesdays NY Times:

UPDATED OCTOBER 7, 2014 12:53 PM

Expanding the Right to Die

INTRODUCTION

André da Loba
Some readers who commented on a Room for Debate forum about the dismal state of elder care said they wanted to be able to end their lives on their own terms to avoid a drawn-out, onerous death. A 29-year-old woman with terminal brain cancer has announced a campaign to support physician-assisted suicide leading up to her own death next month. Since Oregon became the first state to legalize physician-assisted suicide for terminally ill patients, Montana, New Mexico, Vermont and Washington have permitted it.
Should the right to die be expanded further, and if so, what should the standards be?
