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.
Black poverty is fundamentally distinct from white poverty—and so cannot be addressed without grappling with racism.
There have been a number of useful entries in the weeks since Senator Bernie Sanders declared himself against reparations. Perhaps the most clarifying comes from Cedric Johnson in a piece entitled, “An Open Letter To Ta-Nehisi Coates And The Liberals Who Love Him.” Johnson’s essay offers those of us interested in the problem of white supremacy and the question of economic class the chance to tease out how, and where, these two problems intersect. In Johnson’s rendition, racism, in and of itself, holds limited explanatory power when looking at the socio-economic problems which beset African Americans. “We continue to reach for old modes of analysis in the face of a changed world,” writes Johnson. “One where blackness is still derogated but anti-black racism is not the principal determinant of material conditions and economic mobility for many African Americans.”
As Coldplay blandly strained for the universal, she and Bruno Mars pulled off something more specific and more daring.
What a perfect Beyoncésong name: “Formation.” All great pop involves people acting in formation. So does all great change. And while fans scream that Beyoncé’s a “queen” and “goddess,” her core appeal really is as a drill sergeant. With Beyoncé in command, greatness is scalable, achievable, for the collective. Everyone waves their hands to the same beat. Everyone walks around like they have hot sauce in their bag.
But in pop and in politics, “everyone” is a loaded term. Stars as ubiquitous as Beyoncé have haters, the “albino alligators” who “Formation” informs us she twirls upon. And in a more general historical sense, “everyone” can be a dangerous illusion that elevates one point of view as universal while minimizing others. Beyoncé gets all of this, it seems. As a pop star, she surely wants to have as broad a reach as possible. But as an artist, she has a specific message, born of a specific experience, meaningful to specific people. Rather than pretend otherwise, she’s going to make art about the tension implied by this dynamic. She’s going to show up to Super Bowl with a phalanx of women dressed as Black Panthers.
Will the Democratic Party nominate a candidate who hasn’t been a member of their party, and who has long denounced it?
When a party chooses its presidential candidate, it also chooses its party leader in the election. This year the Democrats face an unusual situation. Bernie Sanders isn’t just an outsider to the party establishment; he’s not even been a member of the party, and has long excoriated it in unsparing language. Although the media haven’t much focused on this history, the early signs suggest it could become a problem for Sanders in getting the nomination—and a problem for the party if he does get it.
According to the entrance polls at the Iowa caucuses, there was a 30-percentage-point split between self-identified Democrats and independents in their support for Sanders. Hillary Clinton won 56 percent of self-identified Democrats but only 26 percent of independents, while Sanders won only 39 percent of Democrats but 69 percent of independents.
For decades the Man of Steel has failed to find his groove, thanks to a continual misunderstanding of his strengths.
Superman should be invincible. Since his car-smashing debut in 1938, he’s starred in at least one regular monthly comic, three blockbuster films, and four television shows. His crest is recognized across the globe, his supporting cast is legendary, and anybody even vaguely familiar with comics can recount the broad strokes of his origin. (The writer Grant Morrison accomplished it in eight words: “Doomed Planet. Desperate Scientists. Last Hope. Kindly Couple.”) He’s the first of the superheroes, a genre that’s grown into a modern mass-media juggernaut.
And yet, for a character who gains his power from the light of the sun, Superman is curiously eclipsed by other heroes. According to numbers provided by Diamond Distributors, the long-running Superman comic sold only 55,000 copies a month in 2015, down from around 70,000 in 2010—a mediocre showing even for the famously anemic comic-book market. That’s significantly less than his colleague Batman, who last year moved issues at a comparatively brisk 150,000 a month. Mass media hasn’t been much kinder: The longest-running Superman television show, 2001’s Smallville, kept him out of his iconic suit for a decade. Superman Returns recouped its budget at the box office, but proved mostly forgettable.2013’s Man of Steel drew sharp criticism from critics and audiences alike for its bleak tone and rampaging finale. Trailers for the sequel, Batman v Superman: Dawn of Justice, have shifted the focus (and top billing) to the Dark Knight. Worst of all, conventional wisdom puts the blame on Superman himself. He’s boring, people say; he’s unrelatable, nothing like the Marvel characters dominating the sales charts and the box office. More than anything, he seems embarrassing. Look at him. Truth? Justice? He wears his underwear on the outside.
The insects are miniature transformers that can compress to half their size and still run really fast. The creepy little buggers might even inspire a new generation of search and rescue robots.
Cockroaches get everywhere. There they are, somehow, against all odds, in that room that looked to be totally sealed from the outside world, in that cupboard you swore was tightly shut. Now, Kaushik Jayaram and Robert Full from the University of California, Berkeley have discovered the secret behind their feats of infiltration.
By confronting American cockroaches with an ever-narrower series of crevices, the duo found that although this insect typically stands 12 millimeters tall, it can squeeze through gaps of 3 millimeters—the height of two stacked U.S. pennies. It does this by squatting down and then compressing its body by half. It is the world’s worst Transformer: instantly changing shape from a cockroach into a much flatter cockroach. Delightful.
The former president’s heated assault on Bernie Sanders is a reminder of how the Clintons have long reacted to any opposition.
One of my oldest Hillary Clinton memories: Twenty-six years ago, I stood in the second-floor rotunda of the Arkansas Capitol half-listening to a news conference by Tom McRae, an earnest Democrat challenging Governor Bill Clinton for re-election. Then I heard it: Click. Clack. Click. Clack. Click. Clack.
The sound of Hillary Clinton’s low-heeled shoes on a hidden marble hallway jarred McRae, who in 1990 was Bill Clinton’s biggest obstacle to a fifth term and a presidential bid two years later. The first lady of Arkansas rounded the corner and stormed his news conference. “Tom!” she shouted. “I think we oughta get the record straight!”
Waving a sheaf of papers, Hillary Clinton undercut McRae’s criticism of her husband’s record by pointing to McRae’s past praise of the governor. It was a brutal sandbagging. “Many of the reports you issued not only praise the governor on his environmental record,” she said, “but his education and his economic record!”
Tracking them down is a globe-trotting adventure that rivals any jungle expedition.
In the darkness of the Akeley Hall of Mammals, swarms of kids gawk at beautifully staged dioramas of Africa’s wildlife. The stuffed safari, nestled in the American Museum of Natural History (AMNH) in New York, includes taxidermied leopards stalking a bush pig, preserved ostriches strutting in front of warthogs, and long-dead baboons cautiously considering a viper. In one corner, in a display marked “Upper Nile Region,” a lone hippo grazes next to a herd of lechwe, roan antelope, and a comically stern shoebill stork.
“This is my favorite one,” says Evon Hekkala, pointing to the display. “There’s a taxidermied crocodile tucked away down there.”
It takes a while to spot it and I have to crane my head to do so, but yes, there it is—a large crocodile, in the back, mouth agape, next to the hippo. It’s mostly hidden from view, and until recently, it was hidden from science, too.
Immediately, the pings from fellow journalists (and media-adjacent folk) came pouring in, all saying something along the lines of, “Can you actually let me know what you find out? I’m addicted to that stuff.”
They mean “addicted” in the jokey, dark-chocolate-and-Netflix-streaming way, but the habit can border on pathological. For me, rock bottom was a recent, obscenely long workday during which an entire 12-pack of coconut La Croix somehow made it down my throat, can by shining can.
In Homs, Syria, where entire city blocks have been reduced to rubble by years of civil war, a Syrian wedding photographer thought of using the destruction of the city as a backdrop for pictures of newlywed couples “to show that life is stronger than death.”
In Homs, Syria, where entire city blocks have been reduced to rubble by years of civil war, a Syrian wedding photographer thought of using the destruction of the city as a backdrop for pictures of newlywed couples “to show that life is stronger than death,” according to AFP photographer Joseph Eid. Here, Nada Merhi, 18, and her husband, Syrian army soldier Hassan Youssef, 27, pose for a series of wedding pictures amid heavily damaged buildings in Homs on February 5, 2016.
The trust people tend to feel toward others in the same ethnic, racial, and political groups makes them easy targets for scammers.
Last week’s ABC mini-series chronicled the most famous financial fraud in recent American history: Bernard Madoff’s $50 billion Ponzi scheme, which devastated elite institutions and families of the American Jewish community. The scale of Madoff’s crimes was breathtaking. There’s much to be said about his crimes—not least about the incompetence of the regulatory apparatus that failed to stop him despite repeated warnings and what researchers Greg Gregoriou and Francois Lhabitant quite appropriately called “a riot of red flags” over many years.
