We hear a lot about energy research and development. Perhaps that's because it's the one sort of policy that Republicans and Democrats generally agree on. But there's a different kind of research that I'd like to see get a lot more attention and funding. I'm talking about research into what various kinds of energy policies actually *do* to shape the technical possibilities open to humanity.
In my time researching energy, most of the people who actually care about where we get our energy from have committed to an energy source, be it oil, gas, traditional nuclear, wind, solar, geothermal, or thorium. Then, they go looking for policies that would benefit their technology. I've also run into a lot of people who believe in inexorable laws of change in energy, whether that's decarbonization or the inevitable rise of natural gas or nuclear power. And I've run into a lot of energy experts who believe in a fairly simple relationship between research money going in and technologies coming out.
Unfortunately, none of these three groups of people is likely to produce very good energy policy. To put it in more mainstream terms, we've got a lot of energy pundits and very few energy Nate Silvers, who put reality (i.e. good data) ahead of ideology and intuition. Don't get me wrong: everyone in energy loves them some data, but few people are interested in using it the way Silver does.
Let me introduce you to a scholar who I think embodies the kind of research we need more of. His name is Gregory Nemet. He did his PhD at Berkeley and now teaches at the University of Wisconsin, Madison. I first discovered his work through a 2006 paper in Energy Policy, "Beyond the Learning Curve: factors influencing cost reductions in photovoltaics." Now, you're probably familiar with the neat story that learning curves tell. They say that as you do something, you get better at it, and because it's a curve, the assumption is that this happens at a fairly consistent (and therefore predictable) rate. This is part of the rationale for supporting photovoltaics after all. They've gotten so much cheaper (orders of magnitude) over the last few decades that proponents suggest they're inevitably going to get cheaper than grid electricity some time in the near future.
But this is just too simple a model for the way the world works. Nemet first demolishes the idea that we can bank on simple learning by experience models that show consistent cost reductions as the amount of solar produced increases. These analyses are super sensitive to small changes in the learning rate or the growth of the market (the number of megawatts of PV production in a given time span). And that's not even taking into account the discontinuities that we know occur in technological development. He raises several other powerful objections based on the literature. All in all, it's a pretty amazing takedown of a common method of analysis.
But he doesn't stop there. He then uses the history of photovoltaics (from 1976-2001) to demonstrate a new way of modeling cost reductions in technology. It's hard to gloss the whole thing, but suffice to say that his model allows him to identify which of the following factors were important for different periods of the technology's evolution in driving down cost: plant size, scaling factor, module efficiency, silicon cost, wafer size, silicon use, yield, polycrystal share, polycrystal cost.
With kind of policy impact might that have? Well, if increasing the size of photovoltaic plants appears to lead to large cost reductions, then it might be a good idea to have a loan program that helps get these sorts of plants built. A loan program much like the one that produced many good outcomes along with a few duds like Solyndra.
But there's a deeper reason to support this kind of research. When people think of technological development as somehow magically proceeding apace, it makes it seem *as if* people's personal and civic interventions don't matter. But of course they do! It's just that when you draw one curve to stick in your PowerPoint, all the decisions that affect the factors above get submerged into a false law of simplistic cost reductions.
Since 2006, Nemet has kept working on important research projects. He's done more work on trying to model the effectiveness of differing government support models, as in this paper on whether subsidies or R&D spending are more likely to bring organic solar cells to market. (In this case, the answer is R&D.)
His most recent work, though, might be his most significant, though I think his current research program is not yet complete. In carious ways, he's been trying to get at a very basic question: do demand-side subsidies work to stimulate technological development? Or might better policies exist? This is more than a theoretical question, given the various tax credits both here and abroad that appear to have pushed low-carbon technologies forward. Note the way I framed his project, which I think he would agree with. This is not about whether Nemet believes government should be subsidizing energy projects or not. This is not about whether solar or wind or nuclear *should* be the future of our energy system. No, this is something more basic and more difficult to answer: how much can subsidies enhance the learning (and therefore cost reductions) that an industry like wind actually does?
If you're curious what his final analysis is, here's the conclusion from an excellent forthcoming paper in the Journal of Policy Analysis and Management. You probably won't be surprised to learn that he makes a nuanced judgment:
The magnitude of public funds at stake add some urgency to improving understanding of the extent and characteristics of knowledge spillovers from learning by doing. The main results here imply that policies that enhance demand are necessary to generate sufficient knowledge from experience. Other insights from this case--especially depreciation and diminishing returns--heighten the value of policy instruments with performance-oriented mechanisms and longevity. That experience-derived knowledge appears to be so ephemeral suggests that we should also consider explicit support for codification and transfer of what is learned.
People labeled “smart” at a young age don’t deal well with being wrong. Life grows stagnant.
ASPEN, Colo.—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.
The second episode of the new season was a slow burner with a dramatic twist.
Let’s start at the beginning, with Frank in bed with his wife, Jordan, discussing water stains on the ceiling and childhood entombments. I don’t know about you guys, but I found this whole bit slack and familiar. Maybe there was a two-minute scene in there, but five? Maybe a more charismatic actor could have pulled off that lengthy monologue. But Vince Vaughn is no Robert Shaw, and his childhood basement is no U.S.S. Indianapolis.
As sunny and smiley as gyms’ front-desk employees can be, they’re covering up a secret that keeps the industry going: Once you’ve signed up for a membership, they don’t want you to come in very often.
In fact, gyms are set up to entice the type of customer who will prepay for months or years and then rarely show up. In order to make money, private clubs need to bring in about 10 times as many members as their weight and cardio rooms can accommodate at any given time. This fact ends up shaping the way gyms are designed as physical spaces. In order to attract the type of people who will buy a membership but probably never work out with any regularity, designers give gyms sleek, hotel-like lobbies where membership paperwork is handled. Meanwhile, the intimidating equipment is kept in the back, out of sight—along with the sometimes intimidating brutes who grunt while using them.
The country's inability to pay its debt or reach a deal makes it the largest nation in history to be in arrears to the IMF.
What happens now?
Greece’s missed payment to the IMF is a milestone—it’s both the first time a developed country has missed such a payment, and the first time a Eurozone country has defaulted on its debt. (Or it’s “in arrears”—as Bouree Lam explains below, the IMF isn’t using consistent terminology.)
But that doesn’t mean automatic expulsion from the Eurozone. Yanis Varoufakis, the country’s finance minister, made the case on his blog three years ago that “a defaulted Greece can easily remain in the Eurozone,” and that in fact “Europe’s optimal strategy is to let Greece default.” The Lisbon Treaty, which forms the legal basis of the European Union, actually makes no provision for a member’s expulsion. A 2009 legal analysis by the ECB found that, “while perhaps feasible through indirect means, a Member State’s expulsion from the EU or EMU [the European Monetary Union], would be legally next to impossible.”
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.
The star has been accused of having a “large blind spot” on issues of race—but testing the boundaries of jokes is part of the process of stand-up.
There’s a fine line in comedy between subversive and offensive, and with every meteoric rise from stand-up to film and television stardom these days, there tends to be controversy over whether or not that line has ever been crossed. Amy Schumer, whose Comedy Central sketch show Inside Amy Schumer has been dominating the Internet on a weekly basis since its third season debuted in April, and who stars in the upcoming Judd Apatow comedy Trainwreck, is the latest figure to experience the pitfalls of being under such sharp scrutiny. A recent profile of Schumer in The Guardian by Monica Heisey, although largely positive, criticizes the comedian for having a “shockingly large blind spot” on race—and cites some clunky jokes she’s made about Latinos as examples.
The question is at the center of the Greek crisis.
In 1961, the economist Robert Mundell published a paper laying out, per the title, “A Theory of Optimum Currency Areas.” In it, he inquired about the appropriate geographic extent of a shared unit of money. Was it the world? A country? Part of a country? A border-spanning region of, say, the western parts of the United States and Canada, with a separate currency circulating in the eastern parts of the two countries?
“It might seem at first that the question is purely academic,” he wrote, “since it hardly seems within the realm of political feasibility that national currencies would ever be abandoned in favor of any other arrangement.” But it was worth considering anyway, in part because “certain parts of the world are undergoing processes of economic integration and disintegration,” and an idea of what an “optimum currency area” would look like could help “clarify the meaning of these experiments.”
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 power in the president’s eulogy for Clementa Pinckney came not from his singing, but from the silence that preceded it.
Coverage of the memorial service held for Reverend Clementa Pinckney in Charleston last week focused largely on the surprising moment when the leader of the free world broke into song. That song, of course, was “Amazing Grace” and the president sang it distinctly in the style of the black church.
For all the attention Obama’s unexpected performance received, though, it’s worth taking another look at the “Amazing Grace” clip, this time watching for the silence. His singing seems to be a release of the collective tension that had been building for a week after the Emanuel A.M.E. shooting. But the preceding pause seems to hold its hearers captive. Though he is frequently interrupted with cheers and amens throughout his eulogy for Reverend Pinckney, the pause he takes 35 minutes into the speech is easily the longest break from the text before him.
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.
