A.I. Makes Surgeons More Efficient, but Does Not Replace Them

(p. B6) Brain surgeons are bringing artificial intelligence and new imaging techniques into the operating room, to diagnose tumors as accurately as pathologists, and much faster, according to a report in the journal Nature Medicine.

The new approach streamlines the standard practice of analyzing tissue samples while the patient is still on the operating table, to help guide brain surgery and later treatment.

The traditional method, which requires sending the tissue to a lab, freezing and staining it, then peering at it through a microscope, takes 20 to 30 minutes or longer. The new technique takes two and a half minutes. Like the old method, it requires that tissue be removed from the brain, but uses lasers to create images and a computer to read them in the operating room.

. . .

Some types of brain tumor are so rare that there is not enough data on them to train an A.I. system, so the system in the study was designed to essentially toss out samples it could not identify.

Over all, the system did make mistakes: It misdiagnosed 14 cases that the humans got right. And the doctors missed 17 cases that the computer got right.

“I couldn’t have hoped for a better result,” Dr. Orringer said. “It’s exciting. It says the combination of an algorithm plus human intuition improves our ability to predict diagnosis.”

In his own practice, Dr. Orringer said that he often used the system to determine quickly whether he had removed as much of a brain tumor as possible, or should keep cutting.

“If I have six questions during an operation, I can get them answered without having six times 30 or 40 minutes,” he said. “I didn’t do this before. It’s a lot of burden to the patient to be under anesthesia for that long.”

Dr. Bederson said that he had participated in a pilot study of a system similar to the one in the study and wanted to use it, and that his hospital was considering acquiring the technology.

“It won’t change brain surgery,” he said, “but it’s going to add a significant new tool, more significant than they’ve stated.”

Jobs Return to “Creative Destruction Parts of the Country”

(p. B5) “If you look, there are a heck of a lot of successful manufacturing parts of the country right now,” Kevin Hassett, the departing chairman of the White House Council of Economic Advisers, said in an interview. “But look at where they’re being created.”

Mr. Hassett drew a distinction between “creative destruction” parts of the country, where the Great Recession wiped out jobs but others sprung up to replace them, and “destruction-destruction” parts, where jobs have been slow to return. Recent factory job growth, he said, was “not necessarily disproportionately in the destruction-destruction places.”

Japan Records Fewest Births Since 1874

(p. A6) Japan has 512,000 fewer people this year than last, according to an estimate released on Tuesday by the country’s welfare ministry. That’s a drop of more than the entire population of the city of Atlanta.

The numbers are the latest sign of Japan’s increasing demographic challenges.

Births in the country — which are expected to drop below 900,000 this year — are at their lowest figure since 1874, when the population was about 70 percent smaller than its current 124 million.

The total number of deaths, on the other hand, is increasing. This year, the figure is expected to reach almost 1.4 million, the highest level since the end of World War II, a rise driven by the country’s increasingly elderly population.

French Labor Law Reduces Firm Innovation

I heard an intriguing paper at the January 2020 AEA meetings in San Diego. It shows that a French labor market regulation discourages firm innovation. The abstract of the working paper version of the paper appears below.

We study the impact of labor regulation on innovation. We exploit the threshold in labor market regulations in France which means that when a firm reaches 50 employees, costs increase substantially. We show theoretically and empirically that the prospect of these regulatory costs discourages firms just below the threshold from innovating (as measured by patent counts). This relationship emerges when looking nonparametrically at patent density around the regulatory threshold and also in a parametric exercise where we examine the heterogeneous response of firms to exogenous market size shocks (from export market growth). On average, firms innovate more when they experience a positive market size shock, but this relationship significantly weakens when a firm is just below the regulatory threshold. Using information on citations we also show suggestive evidence (consistent with our model) that regulation deters radical innovation much less than incremental innovation. This suggests that with size-dependent regulation, companies innovate less, but if they do try to innovate, they “swing for the fence.”

Bay Area Californians Moving to Where Living Costs Less

(p. A1) SAN FRANCISCO — Christine Johnson, a public-finance consultant with an engineering degree, was running for a seat on the San Francisco Board of Supervisors.

She crisscrossed her downtown district talking about her plans to stimulate housing construction, improve public transit and deal with the litter of “needles and poop” that have become a common sight on the city’s sidewalks.

Today, a year after losing the race, Ms. Johnson, who had been in the Bay Area since 2004, lives in Denver with her husband and 4-year-old son. In a recent interview, she spoke for millions of Californians past and present when she described the cloud that high rent and child-care costs had cast over her family’s savings and future.

“I fully intended San Francisco to be my home and wanted to make the neighborhoods better,” she said. “But after the election we started tallying up what life could look like elsewhere, and we didn’t see friends in other parts of the country experiencing challenges the same way.”

. . .

(p. A12) Greg Biggs is adding more machines and moving jobs to cheaper locations. Mr. Biggs is the chief executive of Vander-Bend Manufacturing, a company in San Jose that makes metal products including surgical components and racks where data centers store computer servers. Vander-Bend has doubled its head count over the past five years, to about 900 employees, and pays $17 to $40 an hour for skilled technicians who need training but not a college degree.

This is precisely the sort of middle-income job needed in the Bay Area, which like many urban areas is bifurcating into an economy of high-wage knowledge jobs and low-wage service jobs.

The problem is he can’t find enough workers. The unemployment rate in San Jose is around 2 percent, and many of Vander-Bend’s employees already commute two or more hours to work. To compensate, Mr. Biggs has bought several van-size robot arms that pull metal panels from a pile then stamp them flush, bend their edges and assemble them into racks. He has opened a second location 75 miles away in Stockton, where labor and housing costs are a lot lower.

This is in most ways a success story. Vander-Bend is raising wages and training workers. The machines aren’t replacing jobs but instead make them more efficient, and the company is bringing higher-wage positions to a region that needs more of them. But for workers, even substantial income gains are being offset by rising costs.

At-Home Workers Are Leaving Costly Largest Cities

(p. A1) Kelly Swift grew tired of the Los Angeles area a few years ago so she decided to leave—and take her job with her.

Ms. Swift kept her role in health-care information-technology consulting, and her California salary, when she and her family settled in a suburb of Boise, Idaho. Her employer didn’t mind that she started working from home.

Ms. Swift joined a group of workers fueling a renaissance in U.S. cities that lie outside the major job hubs. People who do their jobs from home, freelance or constantly travel for work are migrating away from expensive urban centers such as Los Angeles and San Francisco toward cheaper cities including Boise; Denver; Austin, Texas; and Portland, Ore., according to economists and local residents.

Wisconsin May Have a Robustly Redundant Labor Market

From Nathan Wiese’s description, below, Wisconsin is described in as what I call a “robustly redundant labor market” in my book Openness to Creative Destruction: Sustaining Innovative Dynamism.

(p. A1) ROSENDALE, Wis.—Nathan Wiese, a third-generation dairy farmer who is struggling to get by, says even if he has to close his family’s farm, he feels confident he could hire on as a truck driver and take home more money.

“If you want a job, you can get a job,” said Mr. Wiese, who voted for Donald Trump in 2016 and plans to do so again. “I could probably get one in one day.”

. . .

. . . in an era of severe worker shortages, people losing jobs when a plant or a farm closes are quickly getting scooped up by others. This provides a safety net in the broader economy by keeping incomes and consumer spending strong.

Economists Surprised by Strength of Economy

(p. B3) There are a lot of good things to say, and few bad things to say, about the November [2019] employment numbers that were published Friday morning.

Employers added 266,000 jobs, a blockbuster number even after accounting for the one-time boost of about 41,000 striking General Motors workers who returned to the job.

. . .

Still, there is a bigger lesson contained in the data, one that is important beyond any one month’s tally of the job numbers: that the American economy is capable of cranking at a higher level than conventional wisdom held as recently as a few years ago. As the economy continues to grow well above what once seemed like its potential, without inflation or other clear signs of overheating, it’s clearer that the old view of its potential was an extremely costly mistake.

The mainstream view of the economics profession — held by leaders of the Federal Reserve, the Congressional Budget Office, private forecasters and many in academia — was that the United States economy was at, or close to, full employment.

. . .

People often say that this expansion, now in its 11th year, is growing long in the tooth, or that we are late in the economic cycle. And maybe that’s right. But the biggest lesson when you contrast where the labor market stands at the end of 2019, versus where smart people thought it would stand just a few years ago, is that there’s a lot we don’t know about just what is possible and how strong the United States economy can get.

Local Chinese Governments, Buried in Debt, Ask Citizens for Loans

(p. B1) RUZHOU, China — When the call came for local doctors and nurses to step up for their troubled community, the emergency wasn’t medical. It was financial.

Ruzhou, a city of one million people in central China, urgently needed a new hospital, their bosses said. To pay for it, the administrators were asking health care workers for loans. If employees didn’t have the money, they were pointed to banks where they could borrow it and then turn it over to the hospital.

China’s doctors and nurses are paid a small fraction of what medical professionals make in the United States. On message boards online and in the local media, many complained that they felt pressured to pony up thousands of dollars they could not afford to give.

“It’s like adding insult to injury,” a message posted to an online government forum said. Others, speaking to state and local media, asked why money from lowly employees was needed to build big-ticket government projects.

Ruzhou is a city with a borrowing problem — and an emblem of the trillions of dollars in debt threatening the Chinese economy.

Local governments borrowed for years to create jobs and keep factories humming. Now China’s economy is slowing to its weakest pace in nearly three decades, but Beijing has kept the lending spigots tight to quell its debt problems.

Bicycles Gave Women “Freedom and Self-Reliance”

(p. B8) The decade before the 20th century began saw an explosion in bicycle sales and cycling in general. The so-called “safety bicycle,” with wheels of equal size and a chain mechanism that allowed pedaling to drive the back wheel, along with the arrival of the pneumatic tire, had transformed cycling from an acrobatic and somewhat perilous enterprise into a pleasurable, less hazardous and even utilitarian recreation. Bicycles were mass produced as men increasingly used them to commute to work.

Especially significant was that women, for the first time, took to the activity, relishing the freedom it gave them from the restrictions of a homebound existence. Corsets and billowy skirts even gave way to bloomers so that women could ride comfortably. The bicycle was very much a part of the early women’s movement.

“Let me tell you what I think of bicycling,” the suffragist Susan B. Anthony said in an 1896 interview in The New York World with the pioneering journalist Nellie Bly. “I think it has done more to emancipate women than anything else in the world. I stand and rejoice every time I see a woman ride by on a wheel. It gives woman a feeling of freedom and self-reliance. It makes her feel as if she were independent. The moment she takes her seat she knows she can’t get into harm unless she gets off her bicycle, and away she goes, the picture of free, untrammeled womanhood.”

If ever there was an avatar of these combined social trends, “of free, untrammeled womanhood,” it was Annie Cohen Kopchovsky, a Latvian immigrant who in June 1894, at about age 23, cycled away from her Boston home, leaving a husband and three small children, for a journey around the world.

. . .

Kopchovsky’s celebrity, though it lingered through the completion of her trip, was short-lived, and her adventure would probably have remained obscure were it not for Peter Zheutlin, a journalist and cycling hobbyist who, decades after her death, became intrigued by what little he knew of Kopchovsky, his great-grandfather’s sister. For his book “Around the World on Two Wheels: Annie Londonderry’s Extraordinary Ride” (2007), he scoured newspaper archives from around the world, dug up family relics and plumbed the memory of Kopchovsky’s only survivor, a granddaughter.
