In India’s Public Education System, Teachers Are Often Truant

Matt Ridley has a chapter in his recent The Evolution of Everything, where he cites evidence the low quality of public education in much of the less-developed world. The quality is so low that many poor parents scrimp to pull together modest funds to send their children to modest private schools where the teachers actually show up.

(p. A1) DEORIA, India — The young man, having skipped school, was there to plead his case, but Manoj Mishra was having none of it. When the truant offered a letter from a relative of a government minister pleading for leniency, Mr. Mishra grabbed it and, with a frown, tore it in half and dropped it to the floor.

Similar scenes played out repeatedly in Mr. Mishra’s fluorescent-lit office recently, as one truant after another appeared before him, trying to explain an absence from school.
But these were not students who had been pulled in for truancy. They were teachers.
Mr. Mishra, a district education officer in India’s most populous state, Uttar Pradesh, is fighting one of the biggest obstacles to improving the largest primary school system in the world: absent teachers. His tough punishments and refusal to back down, chronicled in the local newspapers, have turned him into a folk hero. As he walks along the dusty streets of the wheat-farming villages a couple of hours’ drive from Nepal, older people touch his feet in a sign of respect. Young women pull out their phones and take selfies by his side.
When Mr. Mishra arrived in Deoria in 2014, 40 percent of the district’s teachers were absent on any given day from its 2,700 schools, he said in a recent interview. Nationwide, nearly 24 percent of rural Indian teachers were absent during random visits for a recent study led by Kar-(p. A6)thik Muralidharan at the University of California, San Diego. Teacher absences run as high as 46 percent in some states.
. . .
With the largest population in the world under the age of 35, India is trying to grow by leveraging what is often called the “demographic dividend.” To prepare more than 200 million primary school children for jobs in a modern work force, India passed legislation a decade ago that more than doubled education spending, increased teacher salaries and reduced class sizes.
But children’s already low performance has fallen. Pratham Education Foundation, a nonprofit that conducts an annual household survey, reported that in 2005 about 60 percent of fifth graders in rural India — where most people live — could read at a minimum second-grade level, but that in 2014 less than 50 percent could.
Teacher truancy is among the more prominent causes of that failure, experts say. Teaching jobs pay well and are sometimes obtained through political connections. But those who get them often do not want to travel to the remote areas where many schools are. In areas with weak local governance, not showing up has become the norm, and people feel powerless to complain.

New Middle-Skill Jobs Combine Technical and Social Skills

DemingGraphOnMathSocialSkillJobs2015-10-18.jpgSource of graph: online version of the NYT article quoted and cited below, based on Deming paper cited further below.

(p. 4) For all the jobs that machines can now do — whether performing surgery, driving cars or serving food — they still lack one distinctly human trait. They have no social skills.

Yet skills like cooperation, empathy and flexibility have become increasingly vital in modern-day work. Occupations that require strong social skills have grown much more than others since 1980, according to new research. And the only occupations that have shown consistent wage growth since 2000 require both cognitive and social skills.
The findings help explain a mystery that has been puzzling economists: the slowdown in the growth even of high-skill jobs. The jobs hit hardest seem to be those that don’t require social skills, throughout the wage spectrum.
“As I’m speaking with you, I need to think about what’s going on in your head — ‘Is she bored? Am I giving her too much information?’ — and I have to adjust my behavior all the time,” said David Deming, associate professor of education and economics at Harvard University and author of a new study. “That’s a really hard thing to program, so it’s growing as a share of jobs.”
. . .
“If it’s just technical skill, there’s a reasonable chance it can be automated, and if it’s just being empathetic or flexible, there’s an infinite supply of people, so a job won’t be well paid,” said David Autor, an economist at the Massachusetts Institute of Technology. “It’s the interaction of both that is virtuous.”
Mr. Deming’s conclusions are supported by previous research, including that of Mr. Autor. Mr. Autor has written that traditional middle-skill jobs, like clerical or factory work, have been hollowed out by technology. The new middle-skill jobs combine technical and interpersonal expertise, like physical therapy or general contracting.
James Heckman, a Nobel Prize-winning economist, did groundbreaking work concluding that noncognitive skills like character, dependability and perseverance are as important as cognitive achievement. They can be taught, he said, yet American schools don’t necessarily do so.

Technology Extends Capabilities of Older Japanese

(p. A1) TOKYO–At an office-building construction site in the center of Japan’s capital, 67-year-old Kenichi Saito effortlessly stacks 44-pound boards with the ease of a man half his age.
His secret: a bendable exoskeleton hugging his waist and thighs, with sensors attached to his skin. The sensors detect when Mr. Saito’s muscles start to move and direct the machine to support his motion, cutting his load’s effective weight by 18 pounds.
“I can carry as much as I did 10 years ago,” says the hard-hatted Mr. Saito.
Mr. Saito is part of an experiment by Obayashi Corp. , the construction giant handling the building project, to confront one of the biggest problems facing the company and the country: a chronic labor shortage resulting from a rapidly aging population. The exoskeleton has allowed Mr. Saito to extend his working life–and Obayashi to keep building.
. . .
(p. A14) The Fujisawa Aikoen nursing home about an hour outside Tokyo started leasing the “hybrid assistive limb,” or HAL, exoskeletons from maker Cyberdyne Inc. in June.
In Hokkaido, 60-year-old potato-pickers use rubber “smart suits” making it easier to bend over. Baggage handlers at Tokyo’s Haneda airport employ similar assistance.
In cases where older people simply can’t do the job or aren’t available, Japanese manufacturers are turning to robots, which help them keep costs down and continue growing.
Bank of Tokyo Mitsubishi UFJ, Japan’s largest bank, employs a small robot speaking 19 languages to greet customers, while a Nagasaki hotel staffed mainly by robots opened in July. Komatsu Ltd. is developing self-driving vehicles for construction sites, while industrial robot maker Fanuc Corp. is designing machines that repair each other.
Toyota Motor Corp. is testing in homes its “human support robot,” a videophone/remote-controlled android that allows family and friends to perform tasks for distant elderly people as if they were in the same home. In one demonstration, a young man uses a tablet to look around a bed-bound older man’s room, then directs the robot to open the curtains and bring the older man a drink.
SoftBank Group Corp. earlier this year drew global attention when it put on sale in Japan an automaton called Pepper, which it called the world’s first robot capable of understanding emotions. One of the earliest uses for the 4-foot-tall white humanoid is as a nursing helper.
In a Kanagawa Prefecture test, Pepper entertained a room of 30 80- to 90-year-olds for 40 minutes. He led them in light exercises and tested their ability to recognize colors and letters. Women patted his head like a grandchild.
Showing a video of Pepper with a dementia patient on another occasion, Shunji Iyama, one of the developers, says the robot may sometimes work better than people. “That man keeps repeating himself over and over again,” Mr. Iyama said. “If Pepper were human, he’d get fed up, but he just repeats the same reaction and doesn’t get tired.”

To Get the High-Hanging Fruit, Grow Shorter Trees

Dr. Gennaro Fazio, a plant breeder and geneticist with the USDA’s Agricultural Resource Service tells us . . . :

“In taller apple trees, the fruit that is high up, exposed to the sun, ripens the fastest. Low-hanging fruit doesn’t get much sun, and it’s not as ripe — not so delectable, you could say — as the higher fruit. You want to pick the low-hanging fruit last, so it has more time to develop.”

But according to Fazio none of this ultimately matters: the idiom “low-hanging fruit” has been rendered totally and utterly irrelevant by the changing nature of apple tree genetics.
When “low-hanging fruit” became a metaphor in the late 1960s, the majority of apple trees in the U.S. were 25- to 30-foot tall goliaths–and the only fruits within reach were those that lingered on lower branches. Today, however, the majority of apple trees are what arborists refer to as “dwarfs.”
. . .
Once hesitant that the smaller trees wouldn’t produce as much fruit, apple growers realized dwarf trees were actually far more profitable. “Farmers get a higher yield per acre,” says Heather Faubert, of the Rhode Island Fruit Growers Association. “With the taller trees, you could only plant about 20 trees per acre; now, you can get as many as 2,000 in the same space.”
The result of these smaller trees is that the lowest-hanging fruits are actually no longer the easiest to pick. In fact, picking them requires repeatedly bending over to knee-level, a maneuver that can prove incredibly straining on the lower back.
“The ergonomics of picking apples have completely changed,” says Fazio. “It really no longer makes sense to go for the low-hanging fruit. The phrase is irrelevant.”

George Washington as Entrepreneur

(p. C7) While Washington was only an adequate battlefield general, Edward G. Lengel, who oversees George Washington’s papers at the University of Virginia, makes a strong case in “First Entrepreneur” that he was a superb military administrator–skills he learned as a young man serving in the French and Indian War as an aide-de-camp for commanding officers. By carefully monitoring all aspects of the complex business of running a military operation, he held his ragtag army together despite a frequent lack of money, clothing, weapons and food. Without Washington’s management, the Continental Army would likely have disintegrated and the Revolution fizzled out. Mr. Lengel brings needed attention to this vital and neglected aspect of Washington’s generalship.
Washington was also a superb administrator of his own assets. Born to modest wealth, he married into much more and worked hard and creatively to maximize his return on investment. By the end of his life he was one of the new country’s richest men.
Tobacco, the cash crop that had brought prosperity to Virginia, was declining in profitability by the mid-18th century. It exhausted the soil, and prices had been falling on the British market. Washington began to rotate and diversify his crops, import better seed, and exploit Mount Vernon’s other assets, such as the springtime fish runs up the Potomac.
By the end of his life, Washington was not only growing new crops but manufacturing as well, turning his wheat production into both whiskey and flour. When the American inventor Oliver Evans developed a new, more productive type of flour mill, Washington quickly installed one. When the king of Spain sent him a donkey, named Royal Gift, Washington put him to work fathering mules, which were more efficient than horses at farm work. As Mr. Lengel makes clear, Washington was always a bottom-line man, a fact that makes this often remote figure more human.

Spread of Dynamic Pricing Increases Economic Surplus

The theory of consumer and producer surplus implies that total economic surplus will be greater when pricing changes as supply and demand shift. Dynamic pricing increases the extent to which that is possible, and so should increase the total economic surplus (which is the sum of consumer surplus and producer surplus.) Dynamic pricing should also reduce the time consumers waste waiting for the product or service, when pricing is below the market clearing level (like when there are more people seeking a taxi, than there are taxis at the location).

(p. B1) Adult passes to the Indianapolis Zoo used to cost $16.95. Now they set customers back $8 or $30–or almost anywhere in between.
The zoo prices tickets like airfares, changing prices daily based on advance sales and expected demand. It discounts cold weekdays in February and boosts prices after school groups book dozens of tickets. Since introducing such dynamic pricing last year, the zoo’s admission revenue has grown 12%.
. . .
Backed by vast amounts of data and powerful software, more businesses are varying prices by the day, the hour, or even the minute. Online sellers have used such tactics for years, but frequent price (p. B4) changes are increasingly common in the physical world, amplifying the effects of supply and demand on everything from parking spots to golf-course greens fees.
. . .
Previously, a taxi at rush hour went to “the person who happened to be on the right street corner,” said Ian McHenry, the president of Beyond Pricing, which helps homeowners price their rented guest rooms like big hotels. Now, rides go to people willing to pay more, and fewer people “hit the jackpot and get that underpriced reservation or baseball ticket or open cab.”
. . .
“This is not a passing fad,” said Peter Fader, co-director of the University of Pennsylvania’s customer-analytics initiative. Amazon is making dynamic pricing the norm, he said, “and then it’s going to become imperative for the brick-and-mortar players to figure out how to do this.”
The trend is good for business, helping companies charge more for in-demand items and offload surplus goods. Caberfae Peaks ski resort in Cadillac, Mich., said its revenue per customer has surged 17.6% since it began dynamically pricing its advance-sale tickets five years ago.
Variable pricing can also influence behavior. Uber and Lyft raise prices during peak times in part to lure more drivers onto the road.
Highway operators use dynamic pricing to regulate traffic. Over the past two years, Ferrovial SA unit Cintra has opened several toll roads in the Dallas area that can change prices every five minutes to keep speeds above 50 miles an hour. The toll for one 7-mile stretch, for instance, fluctuated between 90 cents and $4.50 in a recent week.
The Indianapolis Zoo said it adopted dynamic pricing in part to limit crowds after opening a new orangutan center last year. The strategy worked: two-thirds of guests visited on weekdays this summer, compared with 57% in 2013.
And Gogo Inc. shifts the price of its in-flight Internet between $8 and $40 based on a flight’s route, day and time to limit the number of users and keep speeds high.
Andrew Sullivan, a products manager at a California manufacturer, recently paid $34 for the Wi-Fi. “It’s a drag as a consumer,” he said. “You’re not getting any additional value when you’re paying twice as much for the same commodity.”
Consumers typically resist dynamic pricing when it is introduced, but then quickly acclimate, Mr. Fader said. Five years ago, Major League Baseball teams caught flak when they began changing ticket prices based on factors such as date, opponent, weather forecasts and seats remaining.
“Now pretty much every one of them is doing it routinely, and doing it with a remarkable lack of backlash,” Mr. Fader said. “The first time, it’s ‘That ain’t right.’ The second time, it’s all right.”

Uber Attracts Older Drivers for the Freedom, Flexibility, Adventure and Money

(p. B1) When Carol Sue Johnson, 73, wheels her silver Mazda S.U.V. out of her driveway in suburban Minneapolis, she doesn’t know how much money she will make driving for the ride-hailing service Uber, but she’s sure she will have an adventure.
Her passengers run the gamut, she said, from three visiting Chinese business executives who were surprised to see a female driver, to teenagers needing a ride to hockey practices or games.
When one group of teenagers “started to get too rowdy,” said Ms. Johnson, who goes by Sue, “one of them told the others to stop because ‘Grandma’s in the car.'”
. . .
(p. B4) For most senior drivers, the biggest advantage is the extra income. Many of those who continue working after 65 do so because they would be too poor otherwise, according to a new report from the labor-backed Economic Policy Institute that found the current retirement system inadequate.
But driving for a ride-booking service, some retirees said, also can offer more than money.
“I love the freedom, the flexibility — and the cash coming in every week,” said Maureen Mahon, 59, who first saw an Uber advertisement on the side of a bus in Manhattan. Ms. Mahon, who lives in Brick Township, N.J., said she had been laid off twice in recent years from Wall Street, and has been driving intermittently since mid-2014.
“I meet businessmen, college kids on their way out for the night, folks going to parties, pretty much the whole range,” she said. “You can drive as much or as little as you like. If the weather’s bad or you have a doctor’s appointment, you just don’t turn on the app.”
Another attraction, compared to driving a taxi, is safety, since customers are screened and no cash is exchanged. So, too, is the opportunity for drivers to shape the job on their own terms.
Driving for Uber “is like a game,” said Stephen B. McPhail, 66, a former charter bus driver who lives in Covington, Wash., south of Seattle. “I like to map out how I spend my time to make the most money.”
An early riser, he gets up at 4:30 a.m. to land several airport rides. Typically, he said, “I work five hours to make between $100 and $150 a day, and I can be done as early as 10 a.m.”

Arbitrary Two Degree Climate Threshold Is Not Backed by Research

(p. A1) Many researchers have argued that a rise in the planet’s average global air temperature of two degrees or more above preindustrial levels would usher in catastrophic climate change. But many others, while convinced the planet is warming, say two degrees is a somewhat arbitrary threshold based on tenuous research, and therefore an impractical spur to policy action.
“It emerged from a political agenda, not a scientific analysis,” said Mark Maslin, professor of climatology at University College London. “It’s not a sensible, rational target because the models give you a range of possibilities, not a single answer.”
Policy makers tend to assume the two-degree target expresses a solid scientific view, but it doesn’t. The exhaustive reports published by the United Nations Intergovernmental Panel on Climate Change are considered to be the most comprehensive analysis of the science of global warming. Yet the two-degree limit isn’t mentioned in a single IPCC report.
. . .
(p. A12) William Nordhaus, a professor of economics at Yale University, appears to have been the first to mention the two-degree figure in a paper published in 1977. But rather than making a robust scientific calculation based on the physics of climate change, his paper argued that a rise of two or more degrees would put the earth’s climate outside the observable range of temperature over the last several hundred thousand years.
. . .
In October 2014, David Victor, a professor of international relations at the University of California, San Diego, and Charles Kennel, a professor at the Scripps Institution of Oceanography in La Jolla, Calif., wrote a sharp critique of the two-degree benchmark in the journal Nature.
They argued that the yardstick was scientifically weak because it captured only a tiny portion of the planet’s climate profile. More than 93% of the extra heat, they noted, ends up in the ocean and not in the atmosphere.

Bernanke’s “Astonishing” Admission that He Tried, and Failed, to Save Lehman

(p. B1) It is astonishing to hear a former Federal Reserve chairman acknowledge that he may have misled the public as part of an agreement with another senior government official about one of the most crucial moments in recent financial history — and that he now questions whether he should have “been more forthcoming.” But that is what Ben S. Bernanke says in his new memoir, “The Courage to Act: A Memoir of a Crisis and Its Aftermath.”
That crucial moment? The bankruptcy of Lehman Brothers. Mr. Bernanke, in perhaps the most candid explanation of Lehman’s 2008 collapse, writes that he and Henry M. Paulson, then the treasury secretary, purposely obfuscated when asked about Lehman’s demise early on, allowing a narrative to develop that the government had purposely let the firm fail.
“In congressional testimony immediately after Lehman’s collapse, Paulson and I were deliberately quite vague when discussing whether we could have saved Lehman,” Mr. Bernanke writes. “But we had agreed in advance to be vague because we were intensely concerned that acknowledging our inability to save Lehman would hurt market confidence and increase pressure on other vulnerable firms.”
. . .
(p. B4) He writes that it was simply impossible to save Lehman, pointing to the nearly $200 billion of losses that Lehman’s creditors have since suffered. No one has come forward on the record, nor has any contemporaneous document been produced in the past seven years that said the government had found a way to save the company and specifically chose not to do so for political reasons, a point Mr. Bernanke alludes to in his book. “I do not want the notion that Lehman’s failure could have been avoided, and that its failure was consequently a policy choice, to become the received wisdom, for the simple reason that it is not true,” he writes. “We did everything we could think of to avoid it.”

Economists Blame Weather for Missed Forecast

(p. C8) Dozens of economists polled by The Wall Street Journal had correctly predicted a drop, but one that was far less severe – negative 0.2% compared with the actual 0.6% month-over-month decline.
But they weren’t bothered by the discrepancy, blaming it on the weather. While that sounds like executives on a conference call throwing up excuses for a “miss” following quarterly earnings, the weather really did play a role. November was unusually mild and utility output was 7.6% lower than a year earlier. Manufacturing, by contrast, rose nearly 1%.
The surprising thing is that this wasn’t anticipated. Since few of the economists surveyed live in balmy places like Florida, they somehow failed to notice that they didn’t have to put on a heavy coat or sweater last month when heading into their offices to crank out forecasts.
