There is no evidence that countries like the United States face debt tipping points
Have you read the opinion section of any newspaper in the last three years? Yes? Then there is a better-than-even chance you have come across some impressive-sounding analyst predict that the United States is "turning into Greece."
Maybe it's been a while, so we'll recap. The short version of this story is that we'll spend ourselves into bankruptcy. The longer version says that too much public debt makes markets nervous. Nervous markets demand higher interest rates. Higher rates mean higher deficits and lower growth, both of which mean more burdensome debt. More burdensome debt makes markets even more nervous. And around and around we go in a vicious circle into insolvency.
As far as scare stories go, this is pretty damn scary. It's also just a story. Rates haven't risen as debt has the last few years; they have fallen to historic lows. Of course, that hasn't stopped the Greek chorus from predicting that the economy is going to Hades. But when? Is it when debt reaches 100 percent of GDP? Or 90 percent, as Carmen Reinhart and Kenneth Rogoff famously argued?
What about 80 percent?
That was the bright white line drawn in a recent paper by David Greenlaw, James Hamilton, Peter Hooper and Frederic Mishkin. Greenlaw & Co. ran regressions on 20 advanced economies from 2000 to 2011 to see if there's a relationship between a country's borrowing costs one year and its gross debt, net debt, and 5-year current account average the previous one. (Glossary Interlude: Gross debt refers to the total amount of debt, including debt the government owes to itself. Net debt is the amount held by the public, minus any government assets. Current account is the balance of trade, which includes both net exports and net income on foreign investments).
They found a link. By their calculations, the coefficients for gross and net debt were "both highly statistically significant", and increasing both debt levels by 1 percentage point of GDP would increase borrowing costs by 4.5 basis points (or 0.045 percentage points). The coefficient for the current account balance was also highly significant, and decreasing the balance by 1 percentage point of GDP would increase borrowing costs by 18 basis points.
This is a big deal. It's not that this regression equation has much predictive power (the authors admit it doesn't) or that the above 4.5 basis points are all that scary; it's the claim that there's a statistically significant relationship between debt and rates. After all, if Greenlaw & Co. are right about debt tipping points, then we are, technically-speaking, screwed. Our gross debt to GDP is already at 102 percent -- enough to send our borrowing costs soaring, as they predict below.
If they are right.
They almost certainly are not.
WHY WE'RE SPECIAL
[Things are about to get very wonky below, so my editor forced me to sum up things here. The two main conclusions are: (1) For countries that can borrow in their own currency, like the U.S., higher debt doesn't clearly lead to higher interest rates. (2) For countries that don't control their currencies, like Greece, it's borrowing too much from foreigners (NOT borrowing too much in general) that clearly leads to much higher borrowing costs. Okay, forward with the wonkiness... ]
Not all debt is created equal. Countries that borrow in a currency they control play under a different set of rules. They can never run out of money to pay back what they owe, since they can always print what they need as a last resort. That's not to say they actually do or should turn to the printing-press to finance themselves. But the option to do so calms markets. After all, inflation is a lot less bad than default for creditors. That's why it's no so easy for countries that don't borrow in a currency they control. They can default. And this is a case where thinking can make things so. Indeed, as Paul De Grauwe points out, countries that don't have their own central bank, like euro members, can fall victim to self-fulfilling panics that push them into bankruptcy. In other words, markets force up interest rates because they fear default -- which then pushes them into default. It's a bank-run on a country.
So we have to answer one big question. How much of Greenlaw & Co.'s results are driven by euro countries that have completely different debt dynamics than non-euro countries?
Well, as Paul Krugman points out, 12 of the 20 countries they look at are either part of the euro, or, in Denmark's case, pegged to it. The remaining ones show no signs of anything resembling debt tipping points. Often the reverse. That's simple enough to see if we break up their sample. The chart below looks at the pre-crisis years from their sample, and shows the non-euro countries in red, the core-euro countries in green, and the (later) troubled PIIGS countries in blue. Back then, at least, there wasn't any difference between -- except for Japan, which had far more debt, and far lower borrowing costs. Nor was there much of any discernible relationship between debt and interest rates.
But then Lehman failed, and the world changed. Debt went up and borrowing costs came down -- except for the PIIGS.
I decided to go back and see what kind of results I'd get if I looked at the non-euro countries and PIIGS separately. I started by trying to recreate the Greenlaw & Co. result for the entire 20-country sample over the 12 years -- which I was able to do, with some very slight differences due to slightly different data sources. (I couldn't find IMF data on long-term interest rates for every country, so I used OECD data to fill in the blanks). Next, I ran a regression with country and time-fixed effects on the non-euro countries -- Australia, Canada, Japan, Norway, Sweden, Switzerland, the U.K., and the U.S. -- from 2000 to 2011. I got coefficients of .00743, .00575, and -0.0695 for gross debt, net debt, and current account, respectively. None of them were statistically significant at the 95 percent level. (The P>t values were 0.13, 0.18, and 0.087).
To translate from stats-speak: our equation for non-euro countries tells us increasing debt by 1 percentage point of GDP only increases borrowing costs by 1.3 basis points. And that result isn't even statistically significant. In other words, there is no evidence of a debt tipping point for countries that borrow in money they can print.
But what about Europe's troubled economies? The Greenlaw & Co. results should hold up there, if nowhere else, right? Well, kind of. I ran another regression with country and time fixed effects on the PIIGS -- Portugal, Italy, Ireland, Greece, and Spain -- from 2000 to 2011, and I got coefficients of 0.0605, 0.0209, and -.8952 for gross debt, net debt, and current account. The coefficients for gross debt and the current account were statistically significant (the latter highly so), but not for net debt, since the PIIGS mostly have the same amount of gross and net debt. (The P>t values were 0.046, 0.342, and 0). I went back and ran the regression again, this time without net debt, and got coefficients of 0.0843 and -0.9157 for gross debt and the current account. Both were highly significant. (The P>t values were 0 for both).
Translated: our equation for the PIIGS tells us increasing debt by 1 percentage point of GDP increases borrowing costs by 8.4 basis points -- but increasing the current account deficit by 1 percentage point of GDP increases borrowing costs by 91 basis points! The PIIGS do have a serious problem, but that problem is borrowing too much from foreigners, not too much government borrowing, in general. Of course, this isn't exactly new information. Paul Krugman, among others, has been pointing out for years that the euro crisis is really a balance of payments crisis that just looks like a debt crisis because of the common currency.
Beware economists bearing regressions -- and journalists too. My sample sizes here are so ridiculously small that the results are hardly dispositive. So don't pay attention to the evidence. Pay attention to the lack of evidence.
There isn't any evidence that the U.S., or other countries that borrow in currencies they control, face some debt tipping point after which borrowing costs spiral out of control. There isn't even much evidence this is true of Europe's troubled economies. Borrowing costs fell for the PIIGS in 2012 (one year after Greenlaw & Co.'s sample ended), not because those countries reduced their debt burdens, but because the ECB promised to do "whatever it takes" to save the euro. A monetary backstop matters more than the amount of debt. Reducing debt isn't as empirically urgent as we hear.

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.
For centuries, experts have predicted that machines would make workers obsolete. That moment may finally be arriving. Could that be a good thing?
1. Youngstown, U.S.A.
The end of work is still just a futuristic concept for most of the United States, but it is something like a moment in history for Youngstown, Ohio, one its residents can cite with precision: September 19, 1977.
For much of the 20th century, Youngstown’s steel mills delivered such great prosperity that the city was a model of the American dream, boasting a median income and a homeownership rate that were among the nation’s highest. But as manufacturing shifted abroad after World War II, Youngstown steel suffered, and on that gray September afternoon in 1977, Youngstown Sheet and Tube announced the shuttering of its Campbell Works mill. Within five years, the city lost 50,000 jobs and $1.3 billion in manufacturing wages. The effect was so severe that a term was coined to describe the fallout: regional depression.
I spent a year in Tromsø, Norway, where the “Polar Night” lasts all winter—and where rates of seasonal depression are remarkably low. Here’s what I learned about happiness and the wintertime blues.
Located over 200 miles north of the Arctic Circle, Tromsø, Norway, is home to extreme light variation between seasons. During the Polar Night, which lasts from November to January, the sun doesn’t rise at all. Then the days get progressively longer until the Midnight Sun period, from May to July, when it never sets. After the midnight sun, the days get shorter and shorter again until the Polar Night, and the yearly cycle repeats.
So, perhaps understandably, many people had a hard time relating when I told them I was moving there.
“I could never live there,” was the most common response I heard. “That winter would make me so depressed,” many added, or “I just get so tired when it’s dark out.”
But the Polar Night was what drew me to Tromsø in the first place.
It wasn’t that bad. But it did help me understand why it made people so angry.
From the Gray Lady, a Modest Dip Proposal. On Microblogging Platform, a Furor. For Peas, a New Use. There are times when The Times out-Timeses itself, and then there was Wednesday. The country's largest newspaper smugly tweeted a link to a recipe for guacamole. One made with peas. "Trust us," it read.
On Wednesday, the United States and Cuba announced that they would reopen embassies in each other’s capitals, thus restoring diplomatic relations for the first time since 1961. The agreement doesn’t mean that Washington-Havana ties will go back to where they were before Fidel Castro’s revolution: Congress still maintains an economic embargo on the island, a policy that’s unlikely to change anytime soon. But the re-establishment of embassies, scheduled to occur on July 20, is nonetheless a major breakthrough in the long-acrimonious relationship between the two countries.
According to The New York Times, the overture to Cuba leaves just three countries with which the United States has no diplomatic relations. Two of these are easy enough to guess: Iran and North Korea. Washington severed ties with Tehran in 1980, months after Iranian students seized the U.S. embassy there and took 52 Americans hostage. U.S. ties with North Korea, meanwhile, have been fraught throughout the latter country’s existence, and have only grown worse since Kim Jong Un assumed control of the country in 2011.
Former Senator Jim Webb is the fifth Democrat to enter the race—and by far the most conservative one.
In a different era’s Democratic Party, Jim Webb might be a serious contender for the presidential nomination. He’s a war hero and former Navy secretary, but he has been an outspoken opponent of recent military interventions. He’s a former senator from Virginia, a purple state. He has a strong populist streak, could appeal to working-class white voters, and might even have crossover appeal from his days as a member of the Reagan administration.
In today’s leftward drifting Democratic Party, however, it’s hard to see Webb—who declared his candidacy Thursday—getting very far. As surprising as Bernie Sanders’s rise in the polls has been, he looks more like the Democratic base than Webb does. The Virginian is progressive on a few major issues, including the military and campaign spending, but he’s far to the center or even right on others: He's against affirmative action, supports gun rights, and is a defender of coal. During the George W. Bush administration, Democrats loved to have him as a foil to the White House. It’s hard to imagine the national electorate will cotton to him in the same way. Webb’s statement essentially saying he had no problem with the Confederate battle flag flying in places like the grounds of the South Carolina capitol may have been the final straw. (At 69, he’s also older than Hillary Clinton, whose age has been a topic of debate, though still younger than Bernie Sanders or Joe Biden.)
The Republican hopeful’s comments about Hispanics have been disastrous for his brand and reputation, which he values at an outlandish $3.3 billion.
Donald Trump’s run for the presidency is premised on one fact above all: He’s a fabulously successful businessman. And yet, paradoxically, running for president may be the most disastrous business decision he’s made—or, at the very least, his worst in a while.
The trouble started with Trump’s rambling announcement speech on June 16. “When Mexico sends its people, they’re not sending the best,” Trump said of immigrants to the United States. “They’re sending people that have lots of problems and they’re bringing those problems. They’re bringing drugs, they’re bringing crime. They’re rapists and some, I assume, are good people, but I speak to border guards and they’re telling us what we’re getting.”
The social network learns more about its users than they might realize.
Facebook, you may have noticed, turned into a rainbow-drenched spectacle following the Supreme Court’s decision Friday that same-sex marriage is a Constitutional right.
By overlaying their profile photos with a rainbow filter, Facebook users began celebrating in a way we haven't seen since March 2013, when 3 million peoplechanged their profile images to a red equals sign—the logo of the Human Rights Campaign—as a way to support marriage equality. This time, Facebook provided a simple way to turn profile photos rainbow-colored. More than 1 million people changed their profile in the first few hours, according to the Facebook spokesperson William Nevius, and the number continues to grow.
“This is probably a Facebook experiment!” joked the MIT network scientist Cesar Hidalgo on Facebook yesterday. “This is one Facebook study I want to be included in!” wrote Stacy Blasiola, a communications Ph.D. candidate at the University of Illinois, when she changed her profile.
Reader requested images, including playful raccoons, Soviet armies leaving Lithuania in the 1990s, Donald Trump’s hair, a Fennec fox, and much more.
Continuing an ongoing experiment, I solicited reader requests for news photos, asking people on Twitter, Facebook and email, "Would you like to see a good photo of a particular subject? A high-res version of a photo you've already seen somewhere else? A photo from a particular photographer or event? If I have access and can find it, I'll try to post it." The subject matter this time was just as varied as before, and the task of finding the images and composing the entry was great fun. Requests this time ranged from a grumpy Judge Scalia to the Soviet army leaving Lithuania in 1990s, guacamole recipes to Donald trump’s hair, and from urban farms in Detroit to playful raccoons. Be sure to see previous Reader Request entries.
People labeled “smart” at a young age don’t deal well with being wrong. Life grows stagnant.
At whatever agesmart people develop the idea that they are smart, they also tend to develop vulnerability around relinquishing that label. So the difference between telling a kid “You did a great job” and “You are smart” isn’t subtle. That is, at least, according to one growing movement in education and parenting that advocates for retirement of “the S word.”
The idea is that when we praise kids for being smart, those kids think: Oh good, I'm smart. And then later, when those kids mess up, which they will, they think: Oh no, I'm not smart after all. People will think I’m not smart after all. And that’s the worst. That’s a risk to avoid, they learn.“Smart” kids stand to become especially averse to making mistakes, which are critical to learning and succeeding.
