Human Intelligence Helps A.I. Work Better

(p. B3) A recent study at the M.I.T. Media Lab showed how biases in the real world could seep into artificial intelligence. Commercial software is nearly flawless at telling the gender of white men, researchers found, but not so for darker-skinned women.
And Google had to apologize in 2015 after its image-recognition photo app mistakenly labeled photos of black people as “gorillas.”
Professor Nourbakhsh said that A.I.-enhanced security systems could struggle to determine whether a nonwhite person was arriving as a guest, a worker or an intruder.
One way to parse the system’s bias is to make sure humans are still verifying the images before responding.
“When you take the human out of the loop, you lose the empathetic component,” Professor Nourbakhsh said. “If you keep humans in the loop and use these systems, you get the best of all worlds.”

Earned Income Matters More Than Equal Income

(p. A13) The concept of a universal basic income, or UBI, has become part of the moral armor of Silicon Valley moguls who want a socially conscious defense against the charge that technology is making humanity obsolete.
. . .
We need policies that encourage job creation and working, not policies that pay people not to work.
In the mid-1960s, about 5% of men aged 25 to 54 were jobless. For 40 years that share has risen, and for much of the past decade the rate has remained over 15%. Suicide, divorce and opioid abuse are all associated with nonemployment, and many facts suggest that the misery of joblessness is far worse than that of a low-paying job. According to the most recent data, only 7% of working men in households earning less than $35,000 report being dissatisfied with their lives. But that share soars to 18% among the nonemployed of all incomes. This suggests that promoting employment is more important than reducing inequality.
. . . 50 years of evidence about labor supply in the U.S. suggests that giving people money will lead them to work less.
The Negative Income Tax experiments of the 1970s–when poorer households in a number of states received direct cash payments to keep them at a minimum income–are the closest America has come to a UBI. But they did not show “minimal impact on work,” as Mr. Yang suggests. Rather, they produced a quite significant work-hours reduction of between 5% and 25%, as well as “employment rate reductions . . . from about 1 to 10 percentage points,” according to one capable study.

Entrepreneur Mackay Deserved to Be Dealt Four Aces

(p. C9) One evening sometime in the 1850s, John Mackay, a prospector, was playing poker with his fellow silver miners in Virginia City, Nev. The wagering was furious, and Mackay was playing well. In one hand, he was dealt an improbable three aces. The man next to him was “betting like a cyclone,” when Mackay drew the astonishing fourth ace, whereupon he laid down his cards and walked away without picking up the pot. “Leave me out, boys,” he said. He didn’t need it. At this point in his life, he had more money than he could ever spend.
. . .
With not a cent to his name, Mackay began swinging a pick ax for subsistence wages on other peoples’ claims, eventually working his way up to mine supervisor. “Mackay tried to cast his imagination into the rock,” Mr. Crouch says, “looking for clues that would lead him to a greater understanding of what wealth lay underground.” By 1865 he had acquired enough cash to buy a stake in a promising mine called the Kentuck. At first the investment looked to be another bust, but it suddenly hit big, paying out $1.6 million of the “precious needful,” as miners called valuable ore, over the next two years.
. . .
The author saves for last an account of the delicious comeuppance Mackay delivered to the American businessman Jay Gould –“the most hated man of the age.” Gould had secured a monopoly on trans-Atlantic telegraphy. Without competition, he gouged users, prompting Mackay, a believer in private enterprise, to lay his own undersea cable, thus breaking Gould’s stranglehold and winning public admiration on both sides of the Atlantic.
Mr. Crouch clearly admires his protagonist, at times nearly to distraction. He portrays Mackay throughout this well-written and worthwhile book as a man of high principle–kind, charitable and fair, dependably doing the noble thing. Strong and silent, he is the Gary Cooper of the sagebrush set. It ever so lightly strains credulity, however, to believe that Mackay didn’t harbor a little larceny in his heart, like nearly everybody on the Comstock during the mad rush. But readers may well want to take the author’s word that a man of such humility and generosity was exactly that. Nowhere will you read John Mackay’s name among the robber barons of his era. Some men who are dealt four aces in life deserve them.

“Meditation Is Demotivating”

(p. 6) . . . on the face of it, mindfulness might seem counterproductive in a workplace setting. A central technique of mindfulness meditation, after all, is to accept things as they are. Yet companies want their employees to be motivated. And the very notion of motivation — striving to obtain a more desirable future — implies some degree of discontentment with the present, which seems at odds with a psychological exercise that instills equanimity and a sense of calm.
To test this hunch, we recently conducted five studies, involving hundreds of people, to see whether there was a tension between mindfulness and motivation. As we report in a forthcoming article in the journal Organizational Behavior and Human Decision Processes, we found strong evidence that meditation is demotivating.

Chinese Communists Subsidize Ghost Town Construction

(p. C3) In China’s Inner Mongolia province, in the middle of the Gobi desert, row upon row of largely vacant apartment towers line the streets of Kangbashi, a new district of the city of Ordos. Earlier this month, Xu Yongfen and his family moved into one 28-story building. In the hallways there are a few signs of life–tricycles, slippers and pink children’s shoes in front of some doors. But most apartments remain unoccupied, their doors still covered in plastic wrap, and at street level, barren storefronts are visible in all directions. “This area is nearly totally empty,” Mr. Xu says, tapping a cigarette into a bowl of ashes at his dining room table.
The city has spent 14 years planning, erecting and maintaining Kangbashi, which has the distinction of being one of China’s best-known “ghost towns”–gleaming but sparsely populated new urban centers adjacent to older metropolises. Built by the dozen across the country, the new areas reflect–and were meant to accelerate–China’s economic boom. As the country’s growth has slowed, many of them have become serious liabilities, deep in debt, with little prospect of full occupancy anytime soon.
. . .
Many of China’s other ghost towns have yet to figure out how to jumpstart their economies without slipping back into the old pattern of borrowing and building. To become economically viable, some may take 20 or 30 years, or “maybe even forever,” said Zhou Jiangping, a professor of urban planning at the University of Hong Kong. In some cases, Mr. Zhou said, local officials encouraged ambitious plans to advance their own careers: “You see all these empty towns, these areas at the edge of cities. They may symbolize the power of some officials.” Because many of them then move on to other jobs, he said, they didn’t think about ensuring long-term growth.
. . .
Ordos City Investment Real Estate Development Co. recently resumed work on two housing projects that it had set aside five years ago, including Mr. Xu’s complex. “Kangbashi’s real-estate sales improved, so our company decided to restart construction,” said Wang Tianyong, a branch manager, noting that the government’s subsidy program favors new projects.

It No Longer Pays to Recycle

(p. B1) Oregon is serious about recycling. Its residents are accustomed to dutifully separating milk cartons, yogurt containers, cereal boxes and kombucha bottles from their trash to divert them from the landfill. But this year, because of a far-reaching rule change in China, some of the recyclables are ending up in the local dump anyway.
In recent months, in fact, thousands of tons of material left curbside for recycling in dozens of American cities and towns — including several in Oregon — have gone to landfills.
. . .
(p. B5) Recycling companies “used to get paid” by selling off recyclable materials, said Peter Spendelow, a policy analyst for the Department of Environmental Quality in Oregon. “Now they’re paying to have someone take it away.”
In some places, including parts of Idaho, Maine and Pennsylvania, waste managers are continuing to recycle but are passing higher costs on to customers, or are considering doing so.
“There are some states and some markets where mixed paper is at a negative value,” said Brent Bell, vice president of recycling at Waste Management, which handles 10 million tons of recycling per year. “We’ll let our customers make that decision, if they’d like to pay more and continue to recycle or to pay less and have it go to landfill.”
Mr. Spendelow said companies in rural areas, which tend to have higher expenses to get their materials to market, were being hit particularly hard. “They’re literally taking trucks straight to the landfill,” he said.

For Job Creation, Firm Youth and Fast Growth Matter More than Small Size

(p. C3) Economist David Birch of the Massachusetts Institute of Technology claimed in the late 1970s–inaccurately, as it turned out–that small businesses were the jobs engine of the economy, which allowed advocates to argue that aid to small businesses was a driver of economic growth. This narrative was reinforced by the wave of startups in the tech sector in the 1980s and 1990s. By 2000, all new businesses, no matter how technologically primitive or undercapitalized, were being called startups. A new biotech company was a startup, but so was a new three-person lawn-mowing business. Only child-labor laws prevented lemonade stands from being classified as startups, too.
A 2010 study published by the National Bureau of Economic Research showed, however, that it is the age of a firm, not its size, that matters for job creation. Just as children grow faster than adults, young firms grow faster than mature ones.
. . .
Government at every level can certainly do more to eliminate unnecessary regulations and to streamline those regulations that serve crucial public ends. But such reforms should benefit all businesses, regardless of size.
. . .
Beyond the injustice of it, small-business favoritism reverberates throughout the economy, slowing growth in two ways. First, subsidies and other size-based industrial policies slow productivity growth by enabling less efficient small firms to gain more market share than would otherwise be the case. Second, discriminatory policies provide an incentive for small firms to remain small. Why add five more workers when doing so would subject you to a host of new regulations and restrict your access to government handouts?

Collaborative Robots (Cobots) Fall in Price and Rise in Ease of Programming

(p. B4) Robots are moving off the assembly line.
Collaborative robots that work alongside humans–“cobots”–are getting cheaper and easier to program. That is encouraging businesses to put them to work at new tasks in bars, restaurants and clinics.
In the Netherlands, a cobot scales a 26-foot-high bar to tap bottles of homemade gin, whiskey and limoncello so that bartenders don’t need to climb ladders. In Japan, a cobot boxes takeout dumplings. In Singapore, robots give soft-tissue massages.
Cobots made up just 5% of the $14 billion industrial-robot market in 2017, according to research by Minneapolis-based venture-capital firm Loup Ventures. Loup estimates sales will jump to 27% of a $33 billion market by 2025 as demand for the robotic arms rises. About 20 manufacturers around the world have started selling such robots in the past decade.

China Will Fail to Corner the Lithium Market

(p. B12) Since emerging as an industrial superpower in the 2000s, China has repeatedly tried to lock up essential resources like iron ore and so-called rare earths. The latest example is lithium, a key battery element: . . . .
. . .
The reality is more mundane.
. . .
. . . it will take just $13 billion in investment to satisfy annual lithium consumption as of 2030, against more $100 billion for nickel and copper.
Even if only a relatively small amount of mining capital spending migrates from mainstays like iron ore into lithium over the next decade, supply probably won’t be a huge problem.

Splendid, Excellent, Salubrious, Salutary, Healthy, Great Jobs Numbers

(p. A16) The real question in analyzing the May jobs numbers released Friday [June 1, 2018] is whether there are enough synonyms for “good” in an online thesaurus to describe them adequately.
So, for example, “splendid” and “excellent” fit the bill. Those are the kinds of terms that are appropriate when the United States economy adds 223,000 jobs in a month, despite being nine years into an expansion, and when the unemployment rate falls to 3.8 percent, a new 18-year low.
“Salubrious,” “salutary” and “healthy” work as words to describe the 0.3 percent rise in average hourly earnings, which are up 2.7 percent over the last year — a nice improvement but also not the kind of sharp increase that might lead the Federal Reserve to rethink its cautious path of interest rate increases.
And a broader definition of unemployment, which includes people who have given up looking for a job out of frustration, fell to 7.6 percent. The jobless rate for African-Americans fell to 5.9 percent, the lowest on record, which we would count as “great.”
If anything, some of the thesaurus offerings don’t really do these numbers justice.
. . .
It isn’t perfect — wage growth remains unexceptional despite its growth spurt in May, and the ratio of prime-age adults working remains below its historical levels.
But it has been a strikingly durable and steady expansion, which is what the nation needed after the scars of the 2008 recession. And that’s just plain “good.”

Those Born Poor, Benefit Less from College Degree

(p. A23) It’s a cruel irony that a college degree is worth less to people who most need a boost: those born poor. This revelation was made by the economists Tim Bartik and Brad Hershbein. Using a body of data, the Panel Study of Income Dynamics, which includes 50 years of interviews with 18,000 Americans, they were able to follow the lives of children born into poor, middle-class and wealthy families.
They found that for Americans born into middle-class families, a college degree does appear to be a wise investment. Those in this group who received one earned 162 percent more over their careers than those who didn’t.
But for those born into poverty, the results were far less impressive. College graduates born poor earned on average only slightly more than did high school graduates born middle class. And over time, even this small “degree bonus” ebbed away, at least for men: By middle age, male college graduates raised in poverty were earning less than nondegree holders born into the middle class. The scholars conclude, “Individuals from poorer backgrounds may be encountering a glass ceiling that even a bachelor’s degree does not break.”
. . .
It shouldn’t here, either: According to the Bureau of Labor Statistics, fewer than 20 percent of American jobs actually require a bachelor’s degree. By 2026, the bureau estimates that this proportion will rise, but only to 25 percent.
Why do employers demand a degree for jobs that don’t require them? Because they can.
What all this suggests is that the college-degree premium may really be a no-college-degree penalty.
