Harvard professor Ken Rogoff has not had a good week (Reuters)
For an economist, the five most terrifying words in the English language are: I can't replicate your results. But for economists Carmen Reinhart and Ken Rogoff of Harvard, there are seven even more terrifying ones: I think you made an Excel error.
Listen, mistakes happen. Especially with Excel. But hopefully they don't happen in papers that provide the intellectual edifice for an economic experiment -- austerity -- that has kept millions out of work. Well, too late. As Mike Konczal of the Roosevelt Institute reported, Thomas Herndon, Michael Ash, and Robert Pollin of the University of Massachusetts, Amherst, have found serious problems with Reinhart and Rogoff's austerity-justifying work. That work, which shows that countries with public debt of 90 percent of GDP or more tend to grow slower, omitted data for five of its 19 countries, and used the wrong data for another. The former was, embarrassingly enough, due to an Excel misadventure, and the latter an unrelated issue. If you use all of the (right) numbers, it turns out growth does slow when debt is high, but not nearly as much as Reinhart and Rogoff -- hereafter, R-R -- claimed.
In other words, there is no evidence for anything resembling a growth tipping point when debt hits 90 percent of GDP.
This is the academic's version of the dream where you're naked in public. Except it's not a dream. It's the mortifying reality for R-R, who have admitted that they forgot to drag their Excel formula down five more cells. But it's worse than mortifying for everybody else. It's been a catastrophe. Not that R-R made a pretty galling mistake; rather, that such a flawed paper gave the intellectual ballast to an idea that has failed everywhere it's been tried the past few years. Now, policymakers would have pursued austerity regardless, but R-R gave them a reason (and seemingly a bright red 90 percent of GDP line) to do so sooner. If too much debt is associated with too little growth, then there's no time to lose for slashing deficits.
Those are important words: "associated with". As I pointed out before, the best argument against taking R-R as austerity's gospel truth was it was just a correlation. Of course a ratio tends to increase more when its denominator increases less. That's how fractions work. But it doesn't prove that the rising ratio causes the stagnating denominator. If anything, the causality runs the other way -- lower growth tends to cause higher debt, as tax revenue falls and safety-net spending rises during a slump. Indeed, as you can see below, Arindrajit Dube of the University of Massachusetts, Amherst, found that debt-to-GDP predicts past GDP growth much better than future GDP growth. In other words, higher debt doesn't cause lower growth as much as lower growth causes higher debt.
Of course, this hasn't stopped deficit hawks from touting R-R's work as proof that we must tackle the long-term debt and we must tackle it now. Including, sometimes, R-R themselves. Now, in their paper, R-R are careful to say the relationship between higher debt and lower growth is just that: a relationship. In fact, that's been their defense: they never said it was anything more than a correlation, and that correlation still holds after correcting for all their mistakes, albeit not as strongly.
That's true ... if you only look at what they said in their paper, and ignore what they said about their paper. For example, here's what they said in Bloomberg View back in July 2011:
Our empirical research on the history of financial crises and the relationship between growth and public liabilities supports the view that current debt trajectories are a risk to long-term growth and stability, with many advanced economies already reaching or exceeding the important marker of 90 percent of GDP....
The biggest risk is that debt will accumulate until the overhang weighs on growth....
Those who remain unconvinced that rising debt levels pose a risk to growth should ask themselves why, historically, levels of debt of more than 90 percent of GDP are relatively rare and those exceeding 120 percent are extremely rare (see attached chart 2 for U.S. public debt since 1790). Is it because generations of politicians failed to realize that they could have kept spending without risk? Or, more likely, is it because at some point, even advanced economies hit a ceiling where the pressure of rising borrowing costs forces policy makers to increase tax rates and cut government spending, sometimes precipitously, and sometimes in conjunction with inflation and financial repression (which is also a tax)?
To be fair, R-R do say that they only found that higher debt and lower growth are "associated" and that there's no "bright red line" (even if policymakers interpret it that way) at 90 percent. But they also make it quite clear that they think their correlation is more than just a correlation. They think higher debt causes lower growth, and, after a little throat-clearing, they're not too shy about saying so.
In a series of academic papers with Carmen Reinhart - including, most recently, joint work with Vincent Reinhart ("Debt Overhangs: Past and Present") - we find that very high debt levels of 90% of GDP are a long-term secular drag on economic growth that often lasts for two decades or more....
Of course, there is two-way feedback between debt and growth, but normal recessions last only a year and cannot explain a two-decade period of malaise. The drag on growth is more likely to come from the eventual need for the government to raise taxes, as well as from lower investment spending. So, yes, government spending provides a short-term boost, but there is a trade-off with long-run secular decline.
It's the same pattern: a few caveats, and then a semi-speculative overselling of their results. But their biggest overselling didn't come in the media. It came behind closed doors -- in Congress. Tim Fernholz of Quartz flagged the following passage from Senator Tom Coburn's recent book about the time R-R briefed members of Congress in April 2011, a few months before the debt ceiling debacle:
Johnny Isakson, a Republican from Georgia and always a gentleman, stood up to ask his question: "Do we need to act this year? Is it better to act quickly?"
"Absolutely," Rogoff said. "Not acting moves the risk closer," he explained, because every year of not acting adds another year of debt accumulation. "You have very few levers at this point," he warned us.
Reinhart echoed Conrad's point and explained that countries rarely pass the 90 percent debt-to-GDP tipping point precisely because it is dangerous to let that much debt accumulate. She said, "If it is not risky to hit the 90 percent threshold, we would expect a higher incidence."
R-R whisper "correlation" to other economists, but say "causation" to everyone else. Now, they don't always say it outright -- at least not at first. Rather, they say "this isn't definitely causation ... but come on, what else could it be?" That's been more than enough for the austerians who have been desperate for any kind of justification to forget about unemployment and worry about debt instead.
The boring reality is the relationship between public debt and growth isn't clear. As Justin Fox of Harvard Business Review points out, there simply isn't enough data. Some countries run up big debts fighting wars, and then grow fine. Some countries run up big debts fighting financial crises, and then grow slowly as the private sector deleverages. Some countries run up big debts as a matter of course, and then grow slowly as rising rates crowd out private investment. And even the few data points we do have don't always tell us all that much. Indeed, as Paul Krugman points out, it shouldn't surprise us that the U.S. has averaged negative growth during its high debt years, because most of those years came during the World War II demobilization. In other words, it's impossible to say anything dispositive about debt and growth more broadly.
But that hasn't stopped R-R from trying. This kind of overhyping is why Joe Weisenthal called them "the most dangerous economists in the world" back in 2011. And it's a far more damning error than anything they did with Excel.
Passengers on a domestic flight deplaning in New York were asked to present ID by Customs and Border Protection agents—a likely unenforceable demand that nevertheless diminishes freedom.
American citizens had their introduction to the Trump-era immigration machine Wednesday, when Customs and Border Protection agents met an airliner that had just landed at New York’s JFK airport after a flight from San Francisco. According to passenger accounts, a flight attendant announced that all passengers would have to show their “documents” as they deplaned, and they did. The reason for the search, Homeland Security officials said, was to assist Immigration and Customs Enforcement in a search for a specific immigrant who had received a deportation order after multiple criminal convictions. The target was not on the flight.
After days of research, I can find no legal authority for ICE or CBP to require passengers to show identification on an entirely domestic fight. The ICE authorizing statute, 8 U.S.C. § 1357, provides that agents can conduct warrantless searches of “any person seeking admission to the United States”—if, that is, the officer has “reasonable cause to suspect” that the individual searched may be deportable. CBP’s statute, 19 U.S.C. § 1467, grants search authority “whenever a vessel from a foreign port or place or from a port or place in any Territory or possession of the United States arrives at a port or place in the United States.” CBP regulations, set out at 19 C.F.R. § 162.6, allow agents to search “persons, baggage, and merchandise arriving in the Customs territory of the United States from places outside thereof.”
When President Obama left, I stayed on at the National Security Council in order to serve my country. I lasted eight days.
In 2011, I was hired, straight out of college, to work at the White House and eventually the National Security Council. My job there was to promote and protect the best of what my country stands for. I am a hijab-wearing Muslim woman––I was the only hijabi in the West Wing––and the Obama administration always made me feel welcome and included.
Like most of my fellow American Muslims, I spent much of 2016 watching with consternation as Donald Trump vilified our community. Despite this––or because of it––I thought I should try to stay on the NSC staff during the Trump Administration, in order to give the new president and his aides a more nuanced view of Islam, and of America's Muslim citizens.
The president has long toyed with the media, but the stakes are much higher now.
American presidents have often clashed with the press. But for a long time, the chief executive had little choice but to interact with journalists anyway.
This was as much a logistical matter as it was a begrudging commitment to the underpinnings of Democracy: News organizations were the nation’s watchdogs, yes, but also stewards of the complex editorial and technological infrastructure necessary to reach the rest of the people. They had the printing presses, then the steel-latticed radio towers, and, eventually, the satellite TV trucks. The internet changed everything. Now, when Donald Trump wants to say something to the masses, he types a few lines onto his pocket-sized computer-phone and broadcasts it to an audience of 26 million people (and bots) with the tap of a button.
Long after research contradicts common medical practices, patients continue to demand them and physicians continue to deliver. The result is an epidemic of unnecessary and unhelpful treatments.
First, listen to the story with the happy ending: At 61, the executive was in excellent health. His blood pressure was a bit high, but everything else looked good, and he exercised regularly. Then he had a scare. He went for a brisk post-lunch walk on a cool winter day, and his chest began to hurt. Back inside his office, he sat down, and the pain disappeared as quickly as it had come.
That night, he thought more about it: middle-aged man, high blood pressure, stressful job, chest discomfort. The next day, he went to a local emergency department. Doctors determined that the man had not suffered a heart attack and that the electrical activity of his heart was completely normal. All signs suggested that the executive had stable angina—chest pain that occurs when the heart muscle is getting less blood-borne oxygen than it needs, often because an artery is partially blocked.
John Krakaeur, a neuroscientist at Johns Hopkins Hospital, has been asked to BRAIN Initiative meetings before, and describes it like “Maleficent being invited to Sleeping Beauty’s birthday.” That’s because he and four like-minded friends have become increasingly disenchanted by their colleagues’ obsession with their toys. And in a new paper that’s part philosophical treatise and part shot across the bow, they argue that this technological fetish is leading the field astray. “People think technology + big data + machine learning = science,” says Krakauer. “And it’s not.”
Each new incident assumes added significance for Muslims and Jews who see them as part of a broader pattern.
Tarek El-Messidi had been planning to leave Philadelphia to visit family on Sunday night. But when he heard that Mount Carmel Jewish Cemetery had been desecrated, he cancelled his flight. El-Messidi is Muslim, but he felt it was important to be with his hometown Jewish community at that moment, he said. “Both communities in America are being targeted right now. There’s a rise in Islamophobia and anti-Semitism,” he said. “That could have just as easily been a Muslim cemetery.”
Just one week after a Jewish cemetery in Missouri was vandalized, Philadelphia police reported that roughly 100 headstones have been toppled or damaged in the Mount Carmel cemetery. These are not easy monuments to knock down, El-Messidi said: He saw several toppled stones that were three or four feet wide at the base. El-Messidi and the local rabbis who showed up on Sunday night said their group observed far more extensive damage than police reported, with more than 500 headstones affected throughout the cemetery. It’s not clear when that damage happened, though, or whether it was all intentional.
Two of the world’s three richest people extol the virtue, and relevance, of optimism in the age of Trump—and predict a comeback for fact-based discourse.
Bill Gates, the world’s richest man, and Warren Buffett, the third richest, are—not entirely coincidentally—two of the most unremittingly optimistic men on the planet. So when I met the two of them in New York recently to talk about the state of humankind, and about the future of American democracy, I had a clear understanding of my mission, which was to pressure-test their sanguinity at every turn.
I tried, and failed, though not completely. Both men appear to doubt some of President Trump’s innovations in rhetoric and policy. Both men have warm feelings about immigrants, and also about facts, and so are predisposed to react skeptically to recent developments in the capital. When I asked whether they believed America needed to be made great again, Buffett nearly jumped out of his chair: “We are great! We are great!” And when I asked about the Trump Administration’s problematic relationship with empiricism, Gates said, “I predict a comeback for the truth.” He went on to say, “To the degree that certain solutions are created not based on facts, I believe these won’t be as successful as those that are based on facts. Democracy is a self-correcting thing.”
You can tell a lot about a person from how they react to something.
That’s why Facebook’s various “Like” buttons are so powerful. Clicking a reaction icon isn’t just a way to register an emotional response, it’s also a way for Facebook to refine its sense of who you are. So when you “Love” a photo of a friend’s baby, and click “Angry” on an article about the New England Patriots winning the Super Bowl, you’re training Facebook to see you a certain way: You are a person who seems to love babies and hate Tom Brady.
The more you click, the more sophisticated Facebook’s idea of who you are becomes. (Remember: Although the reaction choices seem limited now—Like, Love, Haha, Wow, Sad, or Angry—up until around this time last year, there was only a “Like” button.)
The preconditions are present in the U.S. today. Here’s the playbook Donald Trump could use to set the country down a path toward illiberalism.
It’s 2021, and President Donald Trump will shortly be sworn in for his second term. The 45th president has visibly aged over the past four years. He rests heavily on his daughter Ivanka’s arm during his infrequent public appearances.
Fortunately for him, he did not need to campaign hard for reelection. His has been a popular presidency: Big tax cuts, big spending, and big deficits have worked their familiar expansive magic. Wages have grown strongly in the Trump years, especially for men without a college degree, even if rising inflation is beginning to bite into the gains. The president’s supporters credit his restrictive immigration policies and his TrumpWorks infrastructure program.
