Lower Grades for Male Spectators When Their Team Wins

(p. C4) Big-time college-football teams may build school spirit, but they also hurt the grades of male students in the bleachers–at least when the teams are winning, a study suggests.

Economists at the University of Oregon tracked the grades of students there (athletes on all teams excluded) from 1999 through 2007, mapping them against the record of the Ducks, whose fortunes varied from season to season.

Simple Heuristics Can Work Better than Complex Formulas

(p. C4) Most business people and physicians privately admit that many of their decisions are based on intuition rather than on detailed cost-benefit analysis. In public, of course, it’s different. To stand up in court and say you made a decision based on what your thumb or gut told you is to invite damages. So both business people and doctors go to some lengths to suppress or disguise the role that intuition plays in their work.
Prof. Gerd Gigerenzer, the director of the Max Planck Institute for Human Development in Berlin, thinks that instead they should boast about using heuristics. In articles and books over the past five years, Dr. Gigerenzer has developed the startling claim that intuition makes our decisions not just quicker but better.
. . .
The economist Harry Markowitz won the Nobel prize for designing a complex mathematical formula for picking fund managers. Yet when he retired, he himself, like most people, used a simpler heuristic that generally works better: He divided his retirement funds equally among a number of fund managers.
A few years ago, a Michigan hospital saw that doctors, concerned with liability, were sending too many patients with chest pains straight to the coronary-care unit, where they both cost the hospital more and ran higher risks of infection if they were not suffering a heart attack. The hospital introduced a complex logistical model to sift patients more efficiently, but the doctors hated it and went back to defensive decision-making.
As an alternative, Dr. Gigerenzer and his colleagues came up with a “fast-and-frugal” tree that asked the doctors just three sequential yes-no questions about each patient’s electrocardiographs and other data. Compared with both the complex logistical model and the defensive status quo, this heuristic helped the doctors to send more patients to the coronary-care unit who belonged there and fewer who did not.

Internet Companies Respect the Value of Your Time

JainArvindGoogleEngineer2012-03-08.jpg “Arvind Jain, a Google engineer, pointed out the loading speed of individual elements of a website on a test application used to check efficiency, at Google offices in Mountain View, Calif.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) Wait a second.

No, that’s too long.
Remember when you were willing to wait a few seconds for a computer to respond to a click on a Web site or a tap on a keyboard? These days, even 400 milliseconds — literally the blink of an eye — is too long, as Google engineers have discovered. That barely perceptible delay causes people to search less.
“Subconsciously, you don’t like to wait,” said Arvind Jain, a Google engineer who is the company’s resident speed maestro. “Every millisecond matters.”
Google and other tech companies are on a new quest for speed, challenging the likes of Mr. Jain to make fast go faster. The reason is that data-hungry smartphones and tablets are creating frustrating digital traffic jams, as people download maps, video clips of sports highlights, news updates or recommendations for nearby restaurants. The competition to be the quickest is fierce.
People will visit a Web site less often if it is slower than a close competitor by more than 250 milliseconds (a millisecond is a thousandth of a second).
“Two hundred fifty milliseconds, either slower or faster, is close to the magic number now for competitive advantage on the Web,” said Harry Shum, a computer scientist and speed specialist at Microsoft.
. . .
(p. A3) The need for speed itself seems to be accelerating. In the early 1960s, the two professors at Dartmouth College who invented the BASIC programming language, John Kemeny and Thomas Kurtz, set up a network in which many students could tap into a single, large computer from keyboard terminals.
“We found,” they observed, “that any response time that averages more than 10 seconds destroys the illusion of having one’s own computer.”
In 2009, a study by Forrester Research found that online shoppers expected pages to load in two seconds or fewer — and at three seconds, a large share abandon the site. Only three years earlier a similar Forrester study found the average expectations for page load times were four seconds or fewer.
The two-second rule is still often cited as a standard for Web commerce sites. Yet experts in human-computer interaction say that rule is outdated. “The old two-second guideline has long been surpassed on the racetrack of Web expectations,” said Eric Horvitz, a scientist at Microsoft’s research labs.

Upper Class “Have Lost the Confidence to Preach What They Practice”

(p. 9) The problem, Murray argues, is not that members of the new upper class eat French cheese or vote for Barack Obama. It is that they have lost the confidence to preach what they practice, adopting instead a creed of “ecumenical niceness.” They work, marry and raise children, but they refuse to insist that the rest of the country do so, too. “The belief that being a good American involved behaving in certain kinds of ways, and that the nation itself relied upon a certain kind of people in order to succeed, had begun to fade and has not revived,” Murray writes.

“Crises Are an Inevitable Concomitant of Risk”

(p. 11) Some economic risks are worth taking, and crises are an inevitable concomitant of risk. Crises, like firm failures, can be seen as a manifestation of the Schumpeterian process of creative destruction. The role for economic analysis is to ensure that the creation dominates and that the destruction is not too costly.

“Amazed by the Short-Term Psychology in the Market”

(p. A1) Even after European leaders appeared to have averted a chaotic default by Greece with an eleventh-hour deal for aid, worries persist that a debt disaster on the Continent has merely been delayed.

The tortured process that culminated in that latest bailout has exposed the severe limitations of Europe’s approach to the crisis. Many fear that policy makers simply don’t have the right tools to deal with other troubled countries like Italy, Spain, Ireland and Portugal, a situation that could weigh on the markets and the broader economy.
“I don’t want to be a Cassandra, but the idea that it’s over is an illusion,” said Kenneth S. Rogoff, a professor of economics at Harvard and co-author of “This Time Is Different: Eight Centuries of Financial Folly.” “I am amazed by the short-term psychology in the market.”

Few Jobs from Billions Feds Spent on Green Stimulus

WindFarmTexas2012-02-29.jpg “County Commissioner Rosaura Tijerina supported tax breaks for the Cedro Hill wind farm, but it brought few new jobs.” Source of caption and photo: online version of the WSJ review quoted and cited below.

(p. A1) Alfredo Garcia was among the residents of Webb County, Texas, banking on a windfall from federal stimulus money.

Mr. Garcia expanded his Mexican restaurant from 80 to 120 seats, anticipating a rush of new patrons springing from the nearby Cedro Hill wind farm, a project built with the help of $108 million from U.S. taxpayers.
When construction ended, Cedro Hill had just three employees and Mr. Garcia’s restaurant, Aimee’s, filed for bankruptcy protection. “Nobody came,” said Mr. Garcia, a county judge who closed Aimee’s last year, putting 18 people out of work.
Companies have received more than $10 billion to create jobs and renewable energy by building wind farms, solar projects and other alternatives to oil and natural gas under section 1603 of the American Recovery and Reinvestment Act of 2009. The program expired in December, and President Barack Obama proposed last week that Congress revive it in the 2013 budget.
On federal applications, companies said they created more than 100,000 direct jobs at 1603-funded projects. But a Wall Street Journal investigation found evidence of far fewer. Some plants laid off workers. Others closed.
The discrepancies highlight broader challenges calculating the economic benefits of stimulus spending. Jobs have been an important measure influencing distribution of more than $800 billion in stimulus money, which also has included tax breaks and spending on roads, sewers, schools, health and public assis-(p. A10)tance. Yet the number of jobs created or saved is largely based on formulas, mathematical models and reports by recipients, rather than actual tallies.

Amateurs Can Advance Science

(p. C4) The more specialized and sophisticated scientific research becomes, the farther it recedes from everyday experience. The clergymen-amateurs who made 19th-century scientific breakthroughs are a distant memory. Or are they? Paradoxically, in an increasing variety of fields, computers are coming to the rescue of the amateur, through crowd-sourced science.
Last month, computer gamers working from home redesigned an enzyme. Last year, a gene-testing company used its customers to find mutations that increase or decrease the risk of Parkinson’s disease. Astronomers are drawing amateurs into searching for galaxies and signs of extraterrestrial intelligence. The modern equivalent of the Victorian scientific vicar is an ordinary person who volunteers his or her time to solving a small piece of a big scientific puzzle.
Crowd-sourced science is not a recent invention. In the U.S., tens of thousands of people record the number and species of birds that they see during the Christmas season, a practice that dates back more than a century. What’s new is having amateurs contribute in highly technical areas.

(p. 2) PHONING: A friend of mine bought me an Ideos phone on the street in Kenya for about $80. This is an Android phone that’s a bit smaller than an iPhone, but a lot cheaper. This is really exciting because at that price point, hundreds of thousands and soon millions of smartphones are going to be sold across Africa. The impact for people’s access to knowledge in some very difficult places is enormous.

Big Data Opportunity for Economics and Business

(p. 7) Data is not only becoming more available but also more understandable to computers. Most of the Big Data surge is data in the wild — unruly stuff like words, images and video on the Web and those streams of sensor data. It is called unstructured data and is not typically grist for traditional databases.
But the computer tools for gleaning knowledge and insights from the Internet era’s vast trove of unstructured data are fast gaining ground. At the forefront are the rapidly advancing techniques of artificial intelligence like natural-language processing, pattern recognition and machine learning.
Those artificial-intelligence technologies can be applied in many fields. For example, Google’s search and ad business and its experimental robot cars, which have navigated thousands of miles of California roads, both use a bundle of artificial-intelligence tricks. Both are daunting Big Data challenges, parsing vast quantities of data and making decisions instantaneously.
. . .
To grasp the potential impact of Big Data, look to the microscope, says Erik Brynjolfsson, an economist at Massachusetts Institute of Technology’s Sloan School of Management. The microscope, invented four centuries ago, allowed people to see and measure things as never before — at the cellular level. It was a revolution in measurement.
Data measurement, Professor Brynjolfsson explains, is the modern equivalent of the microscope. Google searches, Facebook posts and Twitter messages, for example, make it possible to measure behavior and sentiment in fine detail and as it happens.
In business, economics and other fields, Professor Brynjolfsson says, decisions will increasingly be based on data and analysis rather than on experience and intuition. “We can start being a lot more scientific,” he observes.
. . .
Research by Professor Brynjolfsson and two other colleagues, published last year, suggests that data-guided management is spreading across corporate America and starting to pay off. They studied 179 large companies and found that those adopting “data-driven decision making” achieved productivity gains that were 5 percent to 6 percent higher than other factors could explain.
The predictive power of Big Data is being explored — and shows promise — in fields like public health, economic development and economic forecasting. Researchers have found a spike in Google search requests for terms like “flu symptoms” and “flu treatments” a couple of weeks before there is an increase in flu patients coming to hospital emergency rooms in a region (and emergency room reports usually lag behind visits by two weeks or so).
. . .
In economic forecasting, research has shown that trends in increasing or decreasing volumes of housing-related search queries in Google are a more accurate predictor of house sales in the next quarter than the forecasts of real estate economists. The Federal Reserve, among others, has taken notice. In July, the National Bureau of Economic Research is holding a workshop on “Opportunities in Big Data” and its implications for the economics profession.

In China the Rich and Creative Prepare to Vote with Their Feet

ShiKangBeijingMillionaire2012-02-22.jpg “Shi Kang, a millionaire writer living in Beijing, started thinking about emigrating after a long road trip last year around the U.S.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. A1) BEIJING–This time last year, Shi Kang considered himself a happy man.

Writing 15 novels had made him a millionaire. He owned a luxury apartment and a new silver Mercedes. He was so content with his carefree life in Beijing that he never even traveled overseas.
Today, a year later, Mr. Shi is considering emigrating to the U.S.–one of a growing number of rich Chinese either contemplating leaving their homeland or already arranging to do it.
. . .
(p. A12) A survey published in November found that 60% of about 960,000 Chinese people with assets over 10 million yuan ($1.6 million) were either thinking about emigrating or taking steps to do so. The U.S. was the top destination, followed by Canada, Singapore and Europe, according to the survey by the state-run Bank of China and Hurun Report, which analyzes trends among China’s wealthy.
. . .
Mr. Su was no dissident, though. Like many of his generation, he turned his attention to getting rich. Today, at 46, Mr. Su runs his own aerospace technology company and estimates his own net worth, including the various properties he owns, at around 80 million yuan, or close to $13 million.
His main reason for leaving, he says, is the business environment. “The government has too much power,” he says. “Regulations here mean that businessmen have to do a lot of illegal things. That gives people a real sense of insecurity.” He said four of his distributors have also applied for investment immigration to Canada.
. . .
“The problem is that government power is too great,” Mr. Su says. “When the economy is going up, they think that everything they are doing is right.” If they don’t change, he worries, “another revolution will come soon.”
. . .
The current migrant wave is different in that they are escaping neither poverty nor political unrest–and many say they are leaving for good. The Hurun survey showed that the average respondent had 60 million yuan in assets and was 42, old enough to remember the 1989 Tiananmen crackdown, but young enough to have learned how to prosper in a market economy.
Deng Jie fits the profile. Twenty-seven years ago, in the fledgling years of China’s market reforms, he began his career in a state-run ceramics factory in Beijing, sharing a cramped dormitory with colleagues and earning 50 yuan a month (about $13 in those days).
Today, at 48, he runs his own chemical pigments business and lives with his wife and daughter in one of the three luxury apartments he owns. In dollar terms, he is a millionaire several times over. His properties alone have appreciated by 800% in a decade.
Yet the hope he felt for his country in the 1980s, he says, has “been doused with bucket after bucket of cold water.” He cited a host of concerns, including rampant corruption among the officials he deals with, and new labor regulations that he says have made his work force too costly and demanding.
“I’m representing a lot of other people like me,” he says. “We used to want to contribute to the nation. But now we just feel so disappointed. China cannot continue like this. It has to change.”
