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.
Orr: “It’s a pleasure to meet you, Your Grace. My name is Tyrion Lannister.”
At last! I know I speak for quite a few book readers when I say that pretty much the only thing that kept me going through the eleventy thousand discursive, digressive pages of George R. R. Martin’s fifth tome, A Dance With Dragons, was the promise of Tyrion finally meeting up with Daenerys Targaryen. And, of course, after eleventy thousand pages, it never happened. So on behalf of myself and everyone else who sacrificed sleep, work, family, and friends waiting for this moment, let me say thank you, David Benioff and D. B. Weiss. Bonus points for what seemed to be a cameo by Strong Belwas (a book character who was written out of the show) as the nameless fighter who freed Tyrion from his chains.
Lindsey Graham’s comments about Iranians confirm that some prejudices remain acceptable within the 2016 Republican field.
In important ways, America in recent years has become a less bigoted country. In today’s U.S. Senate, there is no equivalent to Jesse Helms, who during his 1984 reelection race filibustered a federal holiday for Martin Luther King and his 1990 reelection race aired an ad showing a pair of white hands crumpling a job rejection letter as the narrator declared that “they had to give it to a minority because of a racial quota.”
In today’s Republican presidential field, there is no equivalent to Pat Buchanan, who won the 1996 New Hampshire primary after having asked, “Who speaks for the Euro-Americans who founded the U.S.A.?” and having declared that “women are simply not endowed by nature with the same measures of single-minded ambition and the will to succeed in the fiercely competitive world of Western capitalism …. The momma bird builds the nest. So it was, so it ever shall be.” Even the politicians who still wish to deny gays and lesbians equal-marriage rights now insist desperately that they harbor them no malice.
New research confirms what they say about nice guys.
Smile at the customer. Bake cookies for your colleagues. Sing your subordinates’ praises. Share credit. Listen. Empathize. Don’t drive the last dollar out of a deal. Leave the last doughnut for someone else.
Sneer at the customer. Keep your colleagues on edge. Claim credit. Speak first. Put your feet on the table. Withhold approval. Instill fear. Interrupt. Ask for more. And by all means, take that last doughnut. You deserve it.
Follow one of those paths, the success literature tells us, and you’ll go far. Follow the other, and you’ll die powerless and broke. The only question is, which is which?
Of all the issues that preoccupy the modern mind—Nature or nurture? Is there life in outer space? Why can’t America field a decent soccer team?—it’s hard to think of one that has attracted so much water-cooler philosophizing yet so little scientific inquiry. Does it pay to be nice? Or is there an advantage to being a jerk?
The country’s political dysfunction has undermined all efforts to build an effective fighting force.
The Obama administration has run out of patience with Iraq’s Army. On Sunday, Secretary of Defense Ashton Carter appeared on CNN’s “State of the Union” to discuss the recent fall of Ramadi, one of Iraq’s major cities, to ISIS. Despite possessing substantial advantages in both numbers and equipment, he said, the Iraqi military was unable to prevent ISIS forces from capturing the city.
“That says to me and, I think, to most of us, that we have an issue with the will of the Iraqis to fight ISIL and defend themselves.”
Carter’s frustrations are shared by his boss. When asked about the war against ISIS in a recent interview with TheAtlantic’s Jeffrey Goldberg, President Obama said that “if the Iraqis are not willing to fight for the security of their country, then we cannot do it for them.”
For many intellectually disabled people, large campuses or farmsteads may be better options than small group homes. But new state laws could make it hard for big facilities to survive.
In December 2014, I watched 24-year-old Andrew Parles fit wood shapes into a simple puzzle in the new vocational building at the Bancroft Lakeside Campus, a residential program in New Jersey that serves 47 adults with autism and intellectual disabilities. The task wasn’t challenging for Andrew, but his team was taking it slow: Andrew was still recovering from surgery after detaching his own retinas through years of self-injurious behavior. A staff member stood nearby—not hovering, exactly, but close enough to intervene if Andrew suddenly started to hit himself in the head. His mother, Lisa, was hopeful that he’d soon able to participate in the programs he had enjoyed before his surgery: working in Lakeside’s greenhouse, painting in the art studio, delivering food for Meals on Wheels.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Some fans are complaining that Zack Snyder’s envisioning of the Man of Steel is too grim—but it’s less a departure than a return to the superhero’s roots.
Since the official teaser trailer for Batman v Superman: Dawn of Justice debuted online in April, fans and critics alike have been discussing the kind of Superman Zack Snyder is going to depict in his Man of Steel sequel. The controversy stems from Snyder’s decision to cast Superman as a brooding, Dark Knight-like character, who cares more about beating up bad guys than saving people. The casting split has proved divisive among Superman fans: Some love the new incarnation, citing him as an edgier, more realistic version of the character.
But Snyder’s is a different Superman than the one fans grew up with, and many have no problem expressing their outrage over it. Even Mark Waid, the author of Superman: Birthright (one of the comics the original film is based on), voiced his concern about Man of Steel’s turn toward bleakness when it came out in 2013:
Changing neighborhoods may be a class issue, but in America, that means it's also a racial one.
Ask city-dwellers to describe what, precisely, gentrification is you’ll get an array of answers. The term is a murky one, used to describe the many different ways through which money and development enter poorer or less developed neighborhoods, changing them both economically and demographically.
For some, gentrification and gentrifiers are inherently bad—pushing out residents who are often older, poorer, and darker than the neighborhood’s new occupants. For others, a new group of inhabitants brings the possibility of things residents have long hoped for, better grocery stores, new retail, renovations, and an overall revitalization that often eludes low-income neighborhoods.
Video of the encounter suggests another instance of needless escalation and excessive force.
When the Border Patrol stopped Jessica A. Cooke at a checkpoint, the 21-year-old was about to earn her degree in law-enforcement leadership from New York’s public-university system. Due to her course work, she knew her rights as an American. She chose to complain when her rights were violated. And, as a result of that decision, the unarmed woman was pushed, thrown against her car, and tased.
The Watertown Daily Timestells her story, but there’s no substitute for watching the altercation that left her on the ground screaming in pain and incomprehension:
Cooke is an American citizen. The Border Patrol stopped her inside the United States. Although she was close to the Canadian border, she had not crossed into that country. And she produced a New York state driver’s license to confirm her identity. Even if one believes that the Border Patrol ought to operate internal checkpoints within the United States—which I do not—showing a valid I.D. ought to be enough to allow motorists to proceed.
In an interview, the U.S. president ties his legacy to a pact with Tehran, argues ISIS is not winning, warns Saudi Arabia not to pursue a nuclear-weapons program, and anguishes about Israel.
On Tuesday afternoon, as President Obama was bringing an occasionally contentious but often illuminating hour-long conversation about the Middle East to an end, I brought up a persistent worry. “A majority of American Jews want to support the Iran deal,” I said, “but a lot of people are anxiety-ridden about this, as am I.” Like many Jews—and also, by the way, many non-Jews—I believe that it is prudent to keep nuclear weapons out of the hands of anti-Semitic regimes. Obama, who earlier in the discussion had explicitly labeled the supreme leader of Iran, Ayatollah Ali Khamenei, an anti-Semite, responded with an argument I had not heard him make before.
“Look, 20 years from now, I’m still going to be around, God willing. If Iran has a nuclear weapon, it’s my name on this,” he said, referring to the apparently almost-finished nuclear agreement between Iran and a group of world powers led by the United States. “I think it’s fair to say that in addition to our profound national-security interests, I have a personal interest in locking this down.”
