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.
“Here is what I would like for you to know: In America, it is traditional to destroy the black body—it is heritage.”
Last Sunday the host of a popular news show asked me what it meant to lose my body. The host was broadcasting from Washington, D.C., and I was seated in a remote studio on the Far West Side of Manhattan. A satellite closed the miles between us, but no machinery could close the gap between her world and the world for which I had been summoned to speak. When the host asked me about my body, her face faded from the screen, and was replaced by a scroll of words, written by me earlier that week.
The host read these words for the audience, and when she finished she turned to the subject of my body, although she did not mention it specifically. But by now I am accustomed to intelligent people asking about the condition of my body without realizing the nature of their request. Specifically, the host wished to know why I felt that white America’s progress, or rather the progress of those Americans who believe that they are white, was built on looting and violence. Hearing this, I felt an old and indistinct sadness well up in me. The answer to this question is the record of the believers themselves. The answer is American history.
New data shows that students whose parents make less money pursue more “useful” subjects, such as math or physics.
In 1780, John Adams wrote a letter to his wife, Abigail, in which he laid out his plans for what his children and grandchildren would devote their lives to. Having himself taken the time to master “Politicks and War,” two revolutionary necessities, Adams hoped his children would go into disciplines that promoted nation-building, such as “mathematicks,” “navigation,” and “commerce.” His plan was that in turn, those practical subjects would give his children’s children room “to study painting, poetry, musick, architecture, statuary, tapestry, and porcelaine.”
Two-hundred and thirty-five years later, this progression—“from warriors to dilettantes,” in the words of the literary scholar Geoffrey Galt Harpham—plays out much as Adams hoped it would: Once financial concerns have been covered by their parents, children have more latitude to study less pragmatic things in school. Kim Weeden, a sociologist at Cornell, looked at National Center for Education Statistics data for me after I asked her about this phenomenon, and her analysis revealed that, yes, the amount of money a college student’s parents make does correlate with what that person studies. Kids from lower-income families tend toward “useful” majors, such as computer science, math, and physics. Those whose parents make more money flock to history, English, and performing arts.
In 1992, the neuroscientist Richard Davidson got a challenge from the Dalai Lama. By that point, he’d spent his career asking why people respond to, in his words, “life’s slings and arrows” in different ways. Why are some people more resilient than others in the face of tragedy? And is resilience something you can gain through practice?
The Dalai Lama had a different question for Davidson when he visited the Tibetan Buddhist spiritual leader at his residence in Dharamsala, India. “He said: ‘You’ve been using the tools of modern neuroscience to study depression, and anxiety, and fear. Why can’t you use those same tools to study kindness and compassion?’ … I did not have a very good answer. I said it was hard.”
Most adults can’t remember much of what happened to them before age 3 or so. What happens to the memories formed in those earliest years?
My first memory is of the day my brother was born: November 14, 1991. I can remember my father driving my grandparents and me over to the hospital in Highland Park, Illinois, that night to see my newborn brother. I can remember being taken to my mother’s hospital room, and going to gaze upon my only sibling in his bedside cot. But mostly, I remember what was on the television. It was the final two minutes of a Thomas the Tank Engine episode. I can even remember the precise story: “Percy Takes the Plunge,” which feels appropriate, given that I too was about to recklessly throw myself into the adventure of being a big brother.
In sentimental moments, I’m tempted to say my brother’s birth is my first memory because it was the first thing in my life worth remembering. There could be a sliver of truth to that: Research into the formation and retention of our earliest memories suggests that people’s memories often begin with significant personal events, and the birth of a sibling is a textbook example. But it was also good timing. Most people’s first memories date to when they were about 3.5 years old, and that was my age, almost to the day, when my brother was born.
Defining common cultural literacy for an increasingly diverse nation
Is the culture war over?
That seems an absurd question. This is an age when Confederate monuments still stand; when white-privilege denialism is surging on social media; when legislators and educators in Arizona and Texas propose banning ethnic studies in public schools and assign textbooks euphemizing the slave trade; when fear of Hispanic and Asian immigrants remains strong enough to prevent immigration reform in Congress; when the simple assertion that #BlackLivesMatter cannot be accepted by all but is instead contested petulantly by many non-blacks as divisive, even discriminatory.
And that’s looking only at race. Add gender, guns, gays, and God to the mix and the culture war seems to be raging along quite nicely.
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.
The unwillingness of the former secretary of state to take questions from the press contrasts sharply with Jeb Bush’s marked affinity for public disclosure.
Howard Kurtz reported on Sunday night that the Hillary Clinton campaign has decided to open itself to more press interviews. Kurtz quoted the campaign’s communications director, Jennifer Palmieri: “By not doing national interviews until now, Palmieri concedes, ‘we’re sacrificing the coverage. We’re paying a price for it.’”
Meanwhile Jeb Bush chatted July 2 with the conservative website, the Daily Caller. The Daily Caller interview broke an unusually protracted no-interview period for Bush. It had been more than two weeks since he appeared on the Tonight show with Jimmy Fallon. Bush spoke that same day, June 17, to Sean Hannity’s radio show and ABC News. Five days earlier, he’d spoken to Germany’s Der Spiegel—altogether, five interviews in the month of June. That brought his total, since the beginning of February, to 39, according to the Bush campaign.*
Gentrification is pushing long-term residents out of urban neighborhoods. Can collective land ownership keep prices down permanently?
AUSTIN, Tex.—Not long ago, inner cities were riddled with crime and blight and affluent white residents high-tailed it to the suburbs, seeking better schools, safer streets, and, in some cases, fewer minority neighbors.
But today, as affluent white residents return to center cities, people who have lived there for years are finding they can’t afford to stay.
Take the case of the capital city of Texas, where parts of East Austin, right next to downtown, are in the process of becoming whiter, and hip restaurants, coffee shops, and even a barcatering to bicyclists are opening. Much of Austin’s minority population, meanwhile, is priced out, and so they’re moving to far-out suburbs such as Pflugerville and Round Rock, where rents are affordable and commutes are long.
Chicago has seen a double-digit increase in the percentage of kids graduating from high school. Skeptics say educators and kids are manipulating the numbers—but does that even matter?
Desiree Cintron’s name used to come up a lot during “kid talk,” a weekly meeting at Chicago’s North-Grand High School at which teachers mull over a short list of freshmen in trouble.
No shock there, says Desiree now, nearly three years later.
“I was gangbanging and fighting a lot,” she says, describing her first few months of high school. “I didn’t care about school. No one cared, so I didn’t care.”
Had Desiree continued to fail in her freshman year, she would have dropped out. She is sure of that. It was only because of a strong program of academic and social supports put together by her teachers that she stuck it out. Desiree pulled up a failing grade and several Ds. She gave up gangbanging and later started playing softball. She connected with a school determined to connect with her.
