I would have you understand that I am all for recycling. Use it up, wear it out, make it do or do without--it was sound advice during World War II, and it still is today. Still, despite my committment to sustainable blogging, I was not pleased to see the Center on Budget and Policy Priorities reissue the graph I blogged about last year in virtually the same form.
I didn't think much of this graph at the time, and I still don't. The effect of the graph is to make it seem as if we could, by simply refusing to extend the Bush tax cuts on high earners, cover virtually all of the Social Security shortfall that is going to be putting immense pressure on the budget deficit over the next century. But this is not the case.
The CBPP gets its figure by taking present values of the Bush upper income tax cuts extended over 75 years, and comparing them to the present value of the Social Security shortfall. For those who haven't taken finance classes, present values are sort of like compound interest, in reverse. Instead of adding up the future gains from interest rates, you discount future cash flows by a discount rate. Why do this? Mostly because of a financial truism: a dollar today is worth more than a dollar tomorrow: it's certain, not risky, and while you can only use a dollar tomorrow, erm, tomorrow, you can use today's dollar either immediately, or at any time in the future.
Present value is a very useful tool for comparing different investment projects. Say you have one investment project that gives you an immediate return, and one that will give you a much higher return eventually, but takes ten years to pay off--a present value calculation lets you assess which project is actually going to be worth more.
But present value has some drawbacks, too. Our contractor was over last night trying to shore up some joists in our basement that were inappropriately cut to run electric wire, and I mentioned to him that I was working on this post. He thought for a minute, and then summed it up perfectly: "It seems to me that you've got two main problems here: liquidity constraint, and an inappropriate discount rate." Just so. Let me see if I can unpack that a little.
Because it discounts future dollars, often quite heavily, cash flows which happen beyond 10-20 years out virtually disappear. In this case, I assume that the CBPP used the same 5.25% discount rate that it used last year. Just to illustrate what the effect of that discount rate is, if you had a guaranteed $100 payment every year for the next 75 years, discounted at 5.25%, the present value of that cash flow would be $1864, versus the $7500 you get from just adding them all together. Over half of that present value comes from the first 14 years of the 75-year period. By twenty years out, that $100 is only worth $35 a year to you.
Now let's assume that someone comes along and offers me a deal: I can buy that guaranteed $100 cash flow, worth $1864, by taking out a loan. That loan has no interest payments for the first 30 years, and then I have to pay back $400 a year from year 30 to year 75. Should I do it?
Present value would say yes! The present value of those future $400 payments is only $1563, much less than the present value of my $100 annual payments that start now. But obviously, I am going to have trouble in year 30 covering my $400 payment with the $100 I am taking in every year.
The difference could be made up in savings; if I could save all my $100 payments at a guaranteed interest rate of 5.25%, then by year 30, the interest on my savings would be $382; using a combination of interest and slow withdrawals, I could pay off the loan and still have $4500 in the bank.
But the government does not borrow and save like normal people--its constraints are different. The closest it can come to saving is to pay off debt. And our debt is not yielding 5.25% right now; our highest-yielding debt is paying 4.375%, which the government is trying to sell more of, not pay off, in order to lengthen the average time-to-maturity of the debt held by the public, which lowers the risks to the Treasury of a sudden interest rate spike.
The average interest rate on debt held by the public is around 3% right now; it hasn't been as high as 3.75% since April 2009.
Now, you might say that this is not an ordinary time, and that when we pay off our debt in the future, we will get a better "return" on our savings. But remember that discount rate: it means that the immediate future is what gives you the most bang for your buck. And we've only got nine years of "savings" before the Social Security shortfall becomes larger than the cost of the Bush tax cuts, as this graph from the invaluable Committee for a Responsible Federal Budget points out:
We're not going to let the Bush tax cuts expire until 2012 at this point, which gives us 2013-9 to save by paying off debt. Let's say that you think that interest rates are going to bounce back to the 4.96 we paid in July of 2007, and we will use all of the money gained from repeal to pay down debt. By my extremely generous estimates (adding in my best estimate of other tax provisions that primarily benefit the rich, and which CBPP claims were not included in the Congressional Budget Office's $700 billion 10-year price tag for the repeal of the high-income tax cuts), by the end of the seven year period we might pay off as much as $600 billion dollars worth of debt. That's not nothing! Which is why we should never have extended the Bush tax cuts for anyone.
But at 5% average interest rates, we'd be saving less than $30 billion a year in interest. Add that to the $80 billion or so the high-income tax cuts will cost us in 2020 and you get $110 billion a year, or about 0.48% of GDP by my calculations. But in 2020, as you can see from the graph, the Social Security shortfall is 0.51% of GDP. By 2025 it hits around 1% of GDP.
Maybe you think interest rates will jump even further? It's certainly possible. But if you think this, then I assume you aren't among the people making fun of the invisible bond vigilantes, or demanding that we borrow more money for stimulus. Assuming that inflation is not going to suddenly zoom to 5% without Ben Bernanke noticing (or reacting), if you think that interest rates are going to hit 7% in 2013, that means you think that the bond market is going to freak out and raise our real interest rates by hundreds of basis points. Given that the average maturity of our debt is currently less than five years, that means we're going to have to roll over a bunch of debt paying less than 3% for a bunch of debt paying more than 7% . . . which to my ears is the same as shrieking "We're screwed!"
Last year I caught a lot of flak for pointing out that most of the heavy lifting was being done by the discounting, and that if you just looked at the cash flows, there wasn't any good way to pay for Social Security over the next 75 years just by repealing the Bush tax cuts for the rich. But you can see this point illustrated in the CBPP's own graph. At right, you'll see their graph from last year. Notice anything different about it from the one above? I mean, other than the fact that they included the cost of all the Bush tax cuts, not just the ones for high earners?
That's right, last year the costs were equal. This year, the Social Security shortfall is almost 15% larger--0.8% of GDP rather than 0.7%. That's the effect of just one year of poor economic growth, and one year closer to the point where the lines cross on that CFRB graph. That alone tells you how much the timing differences in the cash flows are affecting their results, and why this is not a very useful chart.
There's another problem, one which the CFRB points out in its excellent post on the dangers of this comparison. Actually, they too have recycled--they pointed out exactly the same thing last year when the CBPP debuted the graph. Which is that the CBPP's numbers are incredibly sensitive to initial assumptions about the growth rates in these two budget items.
That's not such a problem with Social Security, where the projections are among the most stable we can make. Demographic change is a slow moving disaster. To a first approximation, every single person who will be collecting benefits in 2030 is now living and working in the United States. And the benefits are tied to the taxes that are paid, which means that unless you think we're going to get a giant burst of immigration, the deficit isn't going to widen or narrow overmuch. Furthermore, the benefits are indexed to wages, which means, broadly, to productivity and GDP growth, so there aren't going to be huge upside or downside surprises.
The estimates of the cost of the Bush tax cuts, however, are extraordinarily sensitive to initial assumptions:, as they pointed out last year:
Essentially, CBPP assumes that the growth rates in revenue loss from 2017 through 2020 will continue forever. Over time, the compounding effects of these growth rates are significant -- increasing the value of the cuts to about 1.1 percent of GDP by 2080. Yet tiny changes in some of the numbers they use can drastically alter this number.
For example, they estimate that the tax cuts will cost $99 billion in 2017 and $120 billion in 2020 based off of a combination of Treasury and TPC estimates. We used some TPC tables to estimates these numbers at $102 billion in 2017 and the same $120 billion in 2020. When we tried to roughly apply their methodology using our $102 billion instead of their $99 billion (in other words, a nominal growth rate of about 5.6% instead of 6%) we found that the shortfall only reaches about 0.65 percent of GDP rather than 1.1 percent.
This is not to say that our $102 billion is right and their $99 billion is wrong - both are plausible and surely both will be wrong. The point is that tiny changes in these numbers cause wild swings in the ultimate cash flow results. (Though the magnitude of the present value cost wouldn't swing nearly as much - under the scenario we presented, the present value of the upper-income cuts would be between 0.5 and 0.6 percent of GDP rather than 0.7 percent).
We also tried projecting forward two other ways: assuming that the upper income tax cuts remained a fixed proportion of total revenue under CBO's extended baseline scenario and assuming bracket creep for the upper-income cuts in line with the total bracket creep we estimate in our CRFB baseline.
Here are the results:
The CBPP is entirely right to point out that the Bush tax cuts were extremely costly. Given our parlous fiscal condition, we cannot afford to extend them--we couldn't in 2010, either, but we did it anyway, and that's water under the bridge. Come 2012, they need to expire. But this is what the CBO says our budget looks like if the Bush tax cuts for high earners expire, but the rest of the budget is business-as-usual: "fixing" the AMT and Medicare doctor reimbursement rates, easing the cutbacks made by ObamaCare, and otherwise acting the way we've acted for the last decade:
This is obviously not sustainable. And much of it is simply driven by the growing ratio of retirees to workers, requiring ever-more Social Security and Medicare dollars to sustain them.
That's why I think it's a terrible idea to juxtapose the Bush tax cuts for the wealthy and Social Security in a graph that implies that the costs are roughly the same size. Not just because they're not really equivalent--but because we don't have that money to spend. We're already assuming that we let those tax cuts go in 2012, and the budget picture is still a disaster.
Easing the budget pressure from Social Security is going to require finding new revenue, or new cuts to existing programs--we can't solve the shortfall with revenues we've already spent, any more than you can pay the mortgage with the check you sent to the electric company last week. And those revenues and cuts will have to be large. It is not helpful to imply otherwise. The American public is already unwilling to confront the actual costs of the programs it has. They don't need any more encouragement to push their heads ever deeper into the sand.
The Warriors star is the embodiment of basketball’s analytics revolution.
The Golden State Warriors are now some 15 months in to their turn as one of the best teams in basketball history. Last season, they won 67 games, the most in the NBA in eight years, and secured a championship in June against LeBron James and the Cleveland Cavaliers. This season’s Warriors make last season’s Warriors look like a team that hadn’t yet gotten loose. They started the year winning their first 24 games in a row, a record opening, and as of now have won 46 of 50.
Golden State’s brilliance is more than just statistical. The Warriors are a basketball idyll, a paradise of skill and collaboration. Their offense runs on nifty ballhandling, willing passing, and sublime shooting, with their point guard and reigning NBA Most Valuable Player acting as ringleader. A slim 6’3” and 185 pounds, with a bouncy jog and a barely post-pubescent tuft of beard at his chin, Stephen Curry dribbles with the intentional abandon of a card hustler, flings one-handed passes to all sectors of the court, and shoots better than anyone ever has.
It was the apotheosis of the outsiders—two candidates, written off when their campaigns began, recovering from defeat in Iowa to deliver resounding victories in the Granite State.
In a year of outsider success, Tuesday’s New Hampshire primary was the apotheosis of the outsiders. On the Democratic side, Senator Bernie Sanders coasted to a huge victory over Hillary Clinton. And for the Republicans, Donald Trump regained his footing after a letdown in Iowa, winning about a third of the vote and notching a huge victory over the rest of the GOP field.
The results for the rest of the field threatened to remake the race, too. Ohio Governor John Kasich, a moderate technocrat who had seemed to lack traction throughout the campaign, saw his decision to bet all his marbles on New Hampshire pay off, as he came in second. Meanwhile, Senator Marco Rubio had a painful night, falling to an apparent fifth-place finish with the vote mostly tallied—a major stumbling block to his momentum. Chris Christie, whose demolition of Rubio during Saturday night’s debate helped knock Rubio down, didn’t get much of a boost and seemed headed for the exits. Jeb Bush and Ted Cruz battled for the third and fourth spots, while Carly Fiorina and Ben Carson lagged far behind.
After getting shut down late last year, a website that allows free access to paywalled academic papers has sprung back up in a shadowy corner of the Internet.
There’s a battle raging over whether academic research should be free, and it’s overflowing into the dark web.
Most modern scholarly work remains locked behind paywalls, and unless your computer is on the network of a university with an expensive subscription, you have to pay a fee, often around 30 dollars, to access each paper.
Many scholars say this system makes publishers rich—Elsevier, a company that controls access to more than 2,000 journals, has a market capitalization about equal to that of Delta Airlines—but does not benefit the academics that conducted the research, or the public at large. Others worry that free academic journals would have a hard time upholding the rigorous standards and peer reviews that the most prestigious paid journals are famous for.
The number of American teens who excel at advanced math has surged. Why?
On a sultry evening last July, a tall, soft-spoken 17-year-old named David Stoner and nearly 600 other math whizzes from all over the world sat huddled in small groups around wicker bistro tables, talking in low voices and obsessively refreshing the browsers on their laptops. The air in the cavernous lobby of the Lotus Hotel Pang Suan Kaew in Chiang Mai, Thailand, was humid, recalls Stoner, whose light South Carolina accent warms his carefully chosen words. The tension in the room made it seem especially heavy, like the atmosphere at a high-stakes poker tournament.
Stoner and five teammates were representing the United States in the 56th International Mathematical Olympiad. They figured they’d done pretty well over the two days of competition. God knows, they’d trained hard. Stoner, like his teammates, had endured a grueling regime for more than a year—practicing tricky problems over breakfast before school and taking on more problems late into the evening after he completed the homework for his college-level math classes. Sometimes, he sketched out proofs on the large dry-erase board his dad had installed in his bedroom. Most nights, he put himself to sleep reading books like New Problems in Euclidean Geometry and An Introduction to Diophantine Equations.
Sanders’s youth movement is powered by the energy of the new campus left. What does it believe?
RINDGE, New Hampshire—Twenty-three minutes into his typically rambling, hourlong stump speech in the arena here, at a private liberal-arts college on the Massachusetts border—after he had decried the Koch brothers and the prescription-drug companies, after he had accused Wall Street of bribing its way to deregulation, after he had called out the corporate media and the political establishment—Bernie Sanders turned to the bleachers behind him, which were filled with college students waving blue signs and chanting his name.
A sly, unusual smile crossed his face. “I feel like a rock-n-roll star!” he exclaimed, taking off his jacket and tossing it to a startled youth behind him. He pantomimed tearing off his sweater, too, prompting a fresh chant of “Ber-nie! Ber-nie!” Then he grinned sheepishly. “All right, nothing else is coming off,” he said, and continued to the next topic—the sins of Walmart.
He’s made the once-impossible seem possible—and now all bets are off.
CONCORD, New Hampshire—“Thank you, New Hampshire!” a somber but clearly gratified Bernie Sanders said to a crowd of thrilled supporters in a high-school gymnasium. The 74-year-old democratic socialist from Vermont had just resoundingly won the New Hampshire Democratic primary, dealing an astonishing blow to the Hillary Clinton juggernaut, casting the race into turmoil, and dramatically highlighting the dissatisfaction of the party base with its establishment.
Sanders’s win, he said, had sent a message to the country: “That the government of our great country belongs to all of the people, and not just a handful of wealthy campaign contributors and their super PACs!” The contest, he noted, had inspired record turnout, powered by a force that he implied would make him a better general-election candidate than his rival—“the energy and the excitement that the Democratic Party will need to succeed in November.”
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 and the artist Frank Quitely accomplished it in eight words and four panels: “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.
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.”
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.
Donald Trump is back, Bernie Sanders is blowing up, and Marco Rubio is battered after the New Hampshire primary.
Trump is back, baby! The man who has made his business career by recovering from disasters did the same in his new political career Tuesday, setting aside his weak second-place showing in Iowa and delivering a commanding win in New Hampshire. The victory sets Trump up as the frontrunner for the Republican nomination once again.
How strong a frontrunner is he? There are still those who think he’s an unlikely nominee, but the wind is at his back for the moment. The next GOP contest is February 20 in South Carolina, where polls show him far ahead. And Marco Rubio, who the establishment hoped could rally an anti-Trump, anti-Ted Cruz coalition, had an awful night in the New Hampshire primary, finishing fifth—well short of his stated goal of second. Suddenly, Rubio seems less like the man who can unify the disparate party forces and more like, well, a robot.
