Upward Mobility from Moving to the Robust Redundant Labor Markets of Open Boomtowns

(p. B3) Chicago in 1850 was a muddy frontier town of barely 30,000 people. Within two decades, it was 10 times that size. Within another two decades, that number had tripled. By 1910, Chicago — hog butcher for the world, headquarters of Montgomery Ward, the nerve center of the nation’s rail network — had more than two million residents.
“You see these numbers, and they just look fake,” said David Schleicher, a law professor at Yale who writes on urban development and land use. Chicago heading into the 20th century was the fastest-growing city America has ever seen. It was a classic metropolitan magnet, attracting anyone in need of a job or a raise.
But while other cities have played this role through history — enabling people who were geographically mobile to become economically mobile, too — migration patterns like the one that fed Chicago have broken down in today’s America. Interstate mobility nationwide has slowed over the last 30 years. But, more specifically and of greater concern, migration has stalled in the very places with the most opportunity.
As Mr. Schleicher puts it, local economic booms no longer create boomtowns in America.
. . .
Some people aren’t moving into wealthy regions because they’re stuck in struggling ones. They have houses they can’t sell or government benefits they don’t want to lose. But the larger problem is that they’re blocked from moving to prosperous places by the shortage and cost of housing there. And that’s a deliberate decision these wealthy regions have made in opposing more housing construction, a prerequisite to make room for more people.
Compare that with most of American history. The country’s economic growth has long “gone hand in hand with enormous reallocation of population,” write the economists Kyle Herkenhoff, Lee Ohanian and Edward Prescott in a recent study of what’s hobbling similar population flows now.
. . .
Were it not for all the restrictions on housing in the most productive places — if workers were able to more freely migrate to them — Mr. Herkenhoff and his co-authors and the economists Enrico Moretti and Chang-Tai Hsieh have estimated that the nation’s G.D.P. would be substantially higher. By their calculations, there are millions of workers missing from the Bay Area and metropolitan New York today.
The population growth that is occurring in these metro areas is fueled almost entirely by immigration, as Ryan Avent points out in “The Gated City,” where he makes a similar argument to Mr. Schleicher. If we consider only domestic moves, about 900,000 more people have moved away from New York than to it since 2010. On net, about 47,000 have left both San Jose and Washington, D.C., while Boston has lost a net 36,000.

Millions of Dollars and 30 Years Later, A.I. Still Has Lacks Crucial Common Sense

(p. B6) SAN FRANCISCO — Microsoft’s co-founder Paul Allen said Wednesday [February 28, 2018] that he was pumping an additional $125 million into his nonprofit computer research lab for an ambitious new effort to teach machines “common sense.”
. . .
“To make real progress in A.I., we have to overcome the big challenges in the area of common sense,” said Mr. Allen, who founded the software giant Microsoft in the 1970s with Bill Gates.
. . .
In the mid-1980s, Doug Lenat, a former Stanford University professor, with backing from the government and several of the country’s largest tech companies, started a project called Cyc. He and his team of researchers worked to codify all the simple truths that we learn as children, from “you can’t be in two places at the same time” to “when drinking from a cup, hold the open end up.”
Thirty years later, Mr. Lenat and his team are still at work on this “common sense engine” — with no end in sight.
Mr. Allen helped fund Cyc, and he believes it is time to take a fresh approach, he said, because modern technologies make it easier to build this kind of system.
Mr. Lenat welcomed the new project. But he also warned of challenges: Cyc has burned through hundreds of millions of dollars in funding, running into countless problems that were not evident when the project began. He called them “buzz saws.”

Value of Property Rights Now Seen by One Who Seized Land

(p. 4) MAZOWE, Zimbabwe — The police first came early one morning five years ago, catching villagers by surprise as they worked in their fields. As hundreds of anti-riot police officers jumped down from their vehicles, their commander issued the villagers an order.
“He said that mother and daughter Grace Mugabe wanted this place,” recalled a village leader, Denboy Chaparadza. “So you better move away.”
The villagers understood right away: Grace Mugabe, the wife of Robert Mugabe, who was ousted from power in November after 37 years as Zimbabwe’s leader, and their daughter, Bona, coveted the villagers’ land. The Mugabes already owned property and businesses in Mazowe, about 25 miles north of Harare, the capital, and they were eager to expand.
Before the villagers could object, the police, armed with sticks and iron bars, demolished their modest houses. “Every house,” Mr. Chaparadza said. “They left us out in the open. We felt betrayed.”
. . .
One reason the 146 families who lived in Mazowe felt betrayed by their leader was that they themselves had seized the land from a white farmer in 2000, under Mr. Mugabe’s fast-track land reform program. Now, they risked losing everything to his wife and daughter: 3,100 acres of prime land for farming and cattle ranching that abuts a lake and gold mines.
. . .
Determining who owns the land is a necessary step to development and democratization in Zimbabwe. Nearly all Zimbabweans who benefited from Mr. Mugabe’s land reform policy lack titles, or legal ownership of their property — leaving them at the mercy of the politically powerful.
. . .
Land also remains a tool of political control, one that Mr. Mnangagwa and other leaders of the governing ZANU-PF party have never shown a willingness to relinquish.
. . .
In recent years, as fighting over succession intensified inside ZANU-PF, land was used to punish and to keep people in line.
High-ranking officials expelled from the party had their land seized, or suffered repeated incursions into their properties by party youths. The threat of losing their farms led some officials to stay in ZANU-PF, instead of decamping to new opposition parties.
. . .
Mr. Chaparadza, the village leader, said that as part of any resolution of the land issue, the new government should compensate white farmers.
“Even if they come back, that’s fine as long as they give us another place,” he said. “We won’t deny them. What we need is only some land where we can survive — and title to the land.”

FDA Regulations Stop Vape Shop Innovations

(p. A19) After Kimberly Manor lost her husband to lung cancer, she was inspired to make a dramatic career change. Kimberly now owns and operates Moose Jooce in Lake, Mich., a “vape shop” that sells various electronic nicotine devices. These products use battery-powered coils to vaporize liquids, with differing levels of nicotine or none at all. Thus, vapers may inhale nicotine without the tar or other harmful chemicals in tobacco smoke, since there is no tobacco and no combustion. Scientific evidence suggests this is a much safer alternative to smoking.
Ms. Manor estimates that her business has helped more than 500 people quit smoking, most of them longtime smokers in their 50s or older. Yet the Food and Drug Administration is discouraging more such enterprises. In a regulation issued in 2016 known as the “deeming rule,” the agency ordered that vaping products would be subject to the same regulations developed for the cigarette industry under the Tobacco Control Act of 2009.
The deeming rule has been devastating to businesses like Ms. Manor’s. To give just one example, vape shop owners frequently experiment by mixing new flavors for the liquid “juice.” Now, each separate creation requires its own prohibitively expensive application for FDA approval, which means that vape shops have been forced to stop innovating.

By Many Metrics, Life Is Better Than Ever

(p. A15) . . . , Mr. Easterbrook argues, “at no juncture in American history were people better off than they were in 2016: living standards, per-capita income, buying power, health, safety, liberty, and longevity were at their highest.”
A potent counter to today’s unwarranted pessimism, the author claims, is not just the evidence that can be seen (rising employment, wages, wealth, health, lifespans and so on) but what has not been seen. Granaries, for instance, are not empty: The many predictions made since the 1960s that billions would die of starvation have not come true. “Instead, by 2015, the United Nations reported global malnutrition had declined to the lowest level in history. Nearly all malnutrition that persists is caused by distribution failures or by government corruption, not by lack of supply.” In fact, obesity is rapidly becoming a global problem.
Similarly, even though there are occasional panics, “resources have not been depleted despite the incredible proliferation of people, vehicles, aircraft, and construction.” Instead of oil and gas running out by the year 2000, as some in the 1970s predicted, both “are in worldwide oversupply” along with minerals and ores.
. . .
Data supporting this author’s optimistic observations are presented throughout “It’s Better Than It Looks.” Similar catalogues can be found in books like Steven Pinker’s “Enlightenment Now” (2018), Johan Norberg’s “Progress” (2016), Peter Diamandis and Steven Kotler’s “Abundance” (2012) and Matt Ridley’s “The Rational Optimist” (2010). I even touched on some of the same points in my own “The Moral Arc” (2015). Apparently, though, this chorus is not loud enough, since pessimism remains as prominent as it ever was.

The More Governments Tax, the Less Workers Work

(p. A17) European countries trail the U.S. in working hard and controlling taxes, and their economies have lagged in comparison. France has a tax-to-GDP ratio of about 44%, and in Italy it’s 43%. The French and Italians work almost 30% fewer hours per person than Americans. Notably, the French economy has flatlined since 2010 while Italy’s has contracted.
These patterns are not a coincidence: High taxes discourage work and capital formation. Data from the Organization for Economic Cooperation and Development suggests that a 1% increase in a nation’s tax rate is associated with a 1.4% decrease in hours worked per person in the working-age population. U.S. data dating to the 1970s also shows that higher taxes cause workers to limit their hours, reducing economic output.

Proof of Concept for Regenerating Limbs and Internal Organs

(p. D3) Scientists have decoded the genome of the axolotl, the Mexican amphibian with a Mona Lisa smile. It has 32 billion base pairs, which makes it ten times the size of the human genome, and the largest genome ever sequenced.
The axolotl, endangered in the wild, has been bred in laboratories and studied for more than 150 years. It has the remarkable capacity to regrow amputated limbs complete with bones, muscles and nerves; to heal wounds without producing scar tissue; and even to regenerate damaged internal organs.
This salamander can heal a crushed spinal cord and have it function just like it did before it was damaged. This ability, which exists to such an extent in no other animal, makes its genes of considerable interest.
. . .
The researchers have identified some of the genes involved in regeneration, and some genes that exist only in the axolotl, but there is much work still to be done.

Art Diamond Predicts a 40% Chance that Elon Musk Will Make It to Mars

(p. A1) What are the chances that readers will make it to the end of this article? About 40%.
If you do make it, that prediction will look smart. If you don’t, well, we said the odds were against it.
Such is the nature of the 40% rule, a favorite forecasting tactic of Wall Street analysts and other prognosticators trying to make a bold call without being too bold.
Former British Prime Minister Tony Blair said last month there’s a 40% chance that Brexit will be reversed; Citigroup Inc. analyst Jim Suva wrote that there’s a 40% chance Apple Inc. buys Netflix Inc.; and Nomura Holdings Inc. economist Lewis Alexander said there’s a 40% chance Nafta gets ripped up.
The nice thing about 40% is that you never have to say you were wrong, says Peter Tchir, a market strategist at Academy Securities. Say you predict the Dow Jones Industrial Average has a 40% chance of hitting 30000 before year-end.
“Get it right and you can say ‘See, I was telling everyone it could happen,’ ” he says. “Get it wrong and you can weasel your way out: ‘I didn’t say it was likely, I just said it was a strong possibility.’ “

Independent Snapchat Entrepreneurs Turned Down Facebook’s Three Billion Dollars

(p. A17) Snap Inc. provides a remarkable story, not only because it has accumulated so many users so rapidly but also because it has remained an independent company in the shadow of Facebook, which in 2012 acquired Instagram, also photo-centered, for $1 billion. A year later, noticing Snapchat’s power to attract young users, Facebook offered Snap’s founders $3 billion for the company, a figure that the book’s publisher has rounded down for the title. Mr. Spiegel, the chief executive, said “no,” and Snap’s current market capitalization, around $23 billion, would seem to be sweet vindication. But Snap has yet to figure out how to convert its many users into net profits, and Instagram has shown no compunction about copying Snapchat features and has grown even faster.
. . .
In Mr. Spiegel’s view, sharing snaps–of anything–was enjoyable because the images were ephemeral and didn’t have to be composed for posterity. “It seems odd that at the beginning of the internet everyone decided everything should stick around forever,” he said.

Italian Bureaucracy Leaves Innovative Restaurateur Feeling “Psychologically Violated”

(p. A7) ROME–The campaign leading up to Italy’s national elections on March 4 [2018] has featured populist promises of largess but neglected what economists have long said is the real Italian disease: The country has forgotten how to grow.
Take Gianni Angelilli’s pizzeria in downtown Rome. He uses an innovative dough mix and flexible cooking methods, drawing long lines and rave reviews. But Italy is too bureaucratic, the locals have no money and his ambition isn’t what it used to be, Mr. Angelilli said. If he opens more outlets, they will be abroad.
“Now, foreigners have more desire to eat well than Italians,” he said. “Italy is dead. Italy is finito.”
. . .
Italian politics have become measurably more chaotic since the country’s old party system–largely frozen during the Cold War–collapsed amid corruption scandals in the early 1990s. Data collected by Einaudi economist Luigi Guiso and others show that since 1992, coalitions have become more likely to crumble, lawmakers to defect and governments to need confidence votes in parliament. Politicians jostling for attention push more frequent, longer and more-complicated legislation.
“An excess has cluttered the bureaucratic machine,” says Mr. Guiso. “The country has become cumbersome.”
Yet the weakness of transient politicians has paradoxically made the public administration more powerful, at the same time as constant legal changes immobilize it, he says.
Mr. Guiso has practical experience. He is helping to set up a government-supported program to send young Italians to learn about entrepreneurship in Silicon Valley and at U.S. business schools, and he said Italian civil servants decided a tender offer inviting U.S. organizations to participate could be published in Italian only. After much persuasion, the civil servants agreed to publish the tender in English too–but insisted all applications must be in Italian, said Mr. Guiso. He said political friends apologized, saying there was nothing they could do.
Mr. Angelilli said his encounters with Italian bureaucracy while running his Pinsere pizzeria have left him feeling “psychologically violated.” He said he had to pay a fine recently because his oven’s air extraction, made to comply with European, national and regional laws, ran afoul of new city rules.

Environment Can Affect Which Genes Are Activated

(p. D5) In September 1944, trains in the Netherlands ground to a halt. Dutch railway workers were hoping that a strike could stop the transport of Nazi troops, helping the advancing Allied forces.
But the Allied campaign failed, and the Nazis punished the Netherlands by blocking food supplies, plunging much of the country into famine. By the time the Netherlands was liberated in May 1945, more than 20,000 people had died of starvation.
The Dutch Hunger Winter has proved unique in unexpected ways. Because it started and ended so abruptly, it has served as an unplanned experiment in human health. Pregnant women, it turns out, were uniquely vulnerable, and the children they gave birth to have been influenced by famine throughout their lives.
When they became adults, they ended up a few pounds heavier than average. In middle age, they had higher levels of triglycerides and LDL cholesterol. They also experienced higher rates of such conditions as obesity, diabetes and schizophrenia.
. . .
“How on earth can your body remember the environment it was exposed to in the womb — and remember that decades later?” wondered Bas Heijmans, a geneticist at Leiden University Medical Center in the Netherlands.
Dr. Heijmans, Dr. Lumey and their colleagues published a possible answer, or part of one, on Wednesday in the journal Science Advances. Their study suggests that the Dutch Hunger Winter silenced certain genes in unborn children — and that they’ve stayed quiet ever since.
While all cells in a person’s body share the same genes, different ones are active or silent in different cells. That program largely is locked in place before birth.
But scientists have learned that later experiences — say, exposure to a virus — can cause cells to quiet a gene or boost its activity, sometimes permanently.
The study of this long-term gene control is called epigenetics. Researchers have identified molecules that cells use to program DNA, but how those tools work isn’t entirely clear. One of the best studied is a molecular cap called a methyl group.
At millions of spots across our DNA, genes may carry a methyl group. They seem to silence genes — at least, researchers have found that silenced genes often have a collection of methyl groups lurking nearby.
