You´d be hard put to find a better illustration of the old chestnut about the EMH economist whose friend tells him there´s a banknote lying in the road:
Can't be. If there was a bill on the ground, somebody would have already picked it up.
Where to begin? Most normal people would say: that´s another nail in the already well-sealed coffin of the EMH. But faced with indisputable facts about solar market prices and installation quantities, Cowen´s response is: where´s the solar boom or fossil bust in asset prices? He can´t see one, so the facts must be wrong, or more politely epiphenomenal noise. Note that the objection is not based on any falsifiable hypothesis about solar PV, such as: Germany will have to cancel its solar PV feed-in tariff as unaffordable, silicon feedstock supply will hit a new bottleneck like the one that kept prices from falling in 2004-2008, solar PV will turn out to cause cancer, impotence and obesity or at least will be thought to do so. (Now there´s a hot tip to the oil industry PR men: work up some scares.) For the record, while Germany did reduce its feed-in tariff, China has announced one.
You know, even after two years at Chicago, where like every professor tells you that same joke at least three times every semester, it never gets old, does it?
It's of course perfectly possible that markets are simply not recognizing the danger to fossil fuel stocks, and we are in for a very exciting disruption in the next ten years. (In which case, I am wrong about a carbon tax and other emissions controls; we should just wait eight years.)
On the other hand, it's also possible that people who trade those stocks for a living--some of whom may even be as smart as James Wimberly, have considered this possibility, and don't find it very likely. What might those reasons be?
1) Mindless trend extrapolation is hours of fun for the entire family, but it is incorrect at least as often as it is correct, and possibly more often.
Wimberly uses this graph:
And very possibly prices will keep falling, the way that microchips have. On the other hand, maybe they'll plateau. Wimberly points out that solar panels are fundamentally a manfuacturing business, not a resource business, which is certainly promising . . . but the prices of other manufactured goods that experienced steep declines did not necessarily keep plummeting to zero.
2) Solar panel costs are not the only cost of a solar installation. According to the Energy Bible (which comports roughly with other figures I've seen online), about half the cost, or a little more, of putting in solar panels comes from the cells. The rest comes from the other stuff you need: batteries, transformers, wiring, and labor. As far as I know, the cost of these things is not falling as fast as the cost of solar panels.
Assume that these costs have held relatively steady, with the labor component being the most unstable. Ten years ago, most of the cost of an installation would have been the solar panels. But as those prices decline, the installed cost (without tax incentives) will be increasingly dominated by labor and other materials. Assuming that that graph says what I think it does, that implies that even if cells become free, we'd plateau slightly north of the average electricity price.
3) There's a storage problem. Yes, intriguing things are being done with hot salt and so forth. But how attractive are the costs compared to home installations? What percentage of their total generation costs represent solar cells, versus labor and other things whose prices aren't falling so fast?
Putting the pieces together, our national battery occupies a volume of 4.4 billion cubic meters, equivalent to a cube 1.6 km (one mile) on a side. The size in itself is not a problem: we'd naturally break up the battery and distribute it around the country. This battery would demand 5 trillion kg (5 billion tons) of lead.
A USGS report from 2011 reports 80 million tons (Mt) of lead in known reserves worldwide, with 7 Mt in the U.S. A note in the report indicates that the recent demonstration of lead associated with zinc, silver, and copper deposits places the estimated (undiscovered) lead resources of the world at 1.5 billion tons. That's still not enough to build the battery for the U.S. alone. We could chose to be optimistic and assume that more lead will be identified over time. But let's not ignore completely the fact that at this moment in time time, no one can point to a map of the world and tell you where even 2% of the necessary lead would come from to build a lead-acid battery big enough for the U.S. And even the undiscovered, but suspected lead falls short.
What about cost? At today's price for lead, $2.50/kg, the national battery would cost $13 trillion in lead alone, and perhaps double this to fashion the raw materials into a battery (today's deep cycle batteries retail for four times the cost of the lead within them). But I guarantee that if we really want to use more lead than we presently estimate to exist in deposits, we're not dealing with today's prices. Leaving this caveat aside, the naïve $25 trillion price tag is more than the annual U.S. GDP. Recall that lead-acid is currently the cheapest battery technology. Even if we sacrificed 5% of our GDP to build this battery (would be viewed as a huge sacrifice; nearly a trillion bucks a year), the project would take decades to complete.
But even then, we aren't done: batteries are good for only so many cycles (roughly 1000, depending on depth of discharge), so the national battery would require a rotating service schedule to recycle each part once every 5 years or so. This servicing would be a massive, expensive, and never-ending undertaking.
Moreover, while some sort of battery-replacement would help deal with the base-load problem (solar and wind are more variable than conventional sources, which means they have limited applications), they don't fix the transportation problem. Batteries are heavy and expensive, and as I understand it, absent some fairly radical breakthrough, they won't work at all in aviation; the energy density isn't high enough to permit the plane to take off. They're better for autos, but people don't want the limited range those vehicles currently offer.
4) To really take the market by storm, solar (plus storage) doesn't need to beat the average cost of electricity; it needs to beat the individual cost of each fuel type. DOE seems to think that by 2016 solar is still going to be a lot more expensive per kilowatt hour than other sources:
It's a pretty long haul before they overtake new coal--much less already-existing coal plants, or advanced natural gas.
The most obvious use for solar is as a replacement for expensive peak-load natural gas power (as I understand it, air conditioning causes most of the demand for these plants, so solar would be a nice complement.) But unless it gets massive subsidies, solar (including any storage mechanism you come up with) is going to have to individually defeat each type of electricity plant on price and/or availability, not "the average retail price of electricity"--which already includes some expensive solar and wind power.
Maybe that's possible--though that would still leave transportation to worry about. But that graph doesn't show it.
I'd close by restating Tyler's question in a slightly different way: if the price of solar is really likely to keep falling until it's cheaper than coal, why don't we see this revealed in the behavior of global warming activists? Where are Greens saying "We've decided to move on to more pressing issues, because clearly, the carbon emissions problem is just about solved."
If solar panels really become cheap enough to replace most electric generation, that will be extraordinarily disruptive, in ways that will be both good and bad for the environment. But I'm not seeing a shift away from climate change in order to focus more on, say, sustainable water-use or species conservation. Everyone seems just as worried about climate change as they've ever been, even though such cheap solar panels would render the issue mostly moot.
Revealed preference and market prices certainly can't tell you everything about the future. But they can tell you a lot about what people believe about the future.
Neither truck drivers nor bankers would put up with a system like the one that influences medical residents’ schedules.
The path to becoming a doctor is notoriously difficult. Following pre-med studies and four years of medical school, freshly minted M.D.s must spend anywhere from three to seven years (depending on their chosen specialty) training as “residents” at an established teaching hospital. Medical residencies are institutional apprenticeships—and are therefore structured to serve the dual, often dueling, aims of training the profession’s next generation and minding the hospital’s labor needs.
How to manage this tension between “education and service” is a perennial question of residency training, according to Janis Orlowski, the chief health-care officer of the Association of American Medical Colleges (AAMC). Orlowski says that the amount of menial labor residents are required to perform, known in the profession as “scut work,” has decreased "tremendously" since she was a resident in the 1980s. But she acknowledges that even "institutions that are committed to education … constantly struggle with this,” trying to stay on the right side of the boundary between training and taking advantage of residents.
Plagues, revolutions, massive wars, collapsed states—these are what reliably reduce economic disparities.
Calls to make America great again hark back to a time when income inequality receded even as the economy boomed and the middle class expanded. Yet it is all too easy to forget just how deeply this newfound equality was rooted in the cataclysm of the world wars.
The pressures of total war became a uniquely powerful catalyst of equalizing reform, spurring unionization, extensions of voting rights, and the creation of the welfare state. During and after wartime, aggressive government intervention in the private sector and disruptions to capital holdings wiped out upper-class wealth and funneled resources to workers; even in countries that escaped physical devastation and crippling inflation, marginal tax rates surged upward. Concentrated for the most part between 1914 and 1945, this “Great Compression” (as economists call it) of inequality took several more decades to fully run its course across the developed world until the 1970s and 1980s, when it stalled and began to go into reverse.
The provocateur at the center of the controversy that engulfed the right this weekend offers a qualified mea culpa.
NEW YORK — Milo Yiannopoulos has a new mode, and it’s contrition.
Yiannopoulos appeared before reporters on Tuesday in a rented Soho loft to announce his resignation from Breitbart News and apologize to abuse victims for over-a-year-old remarks on pedophilia that incited a political firestorm over the weekend. Wearing a conservative navy blue suit and sunglasses, which he switched to regular glasses shortly into the conference, Yiannopoulous read a prepared statement in which he said he had been the victim of sexual abuse between the ages of 13 and 16. Yiannopoulos said he was “partly to blame” for the remarks on the tape and that he was “certainly guilty of imprecise language.”
“I haven’t ever apologized before,” Yiannopoulos said. “I don’t anticipate ever doing it again. Name-calling doesn’t bother me, misreporting doesn’t bother me. But to be a victim of child abuse and for the media to call me an apologist for child abuse is absurd. I regret the things I said. I don't think I've been as sorry about anything in my whole life.”
By excusing Donald Trump’s behavior, some evangelical leaders enabled the internet provocateur’s ascent.
The Conservative Political Action Conference (CPAC) takes place this week near Washington, D.C., the first such gathering since Donald Trump took office. The conference purports to be a gathering for like-minded folks who believe, generally, in the well-established principles of the conservative movement, as enunciated by the American Conservative Union.
This year, aside from President Trump himself, activist Milo Yiannopoulos was briefly granted a featured speaking slot, and it caused a lot of disruption, garment-rending, gnashing of teeth, and in-fighting on the right.
Yiannopoulos, who prefers to go by MILO (yes, capitalized), is a controversial figure with dubious conservative credentials, most famous for being outrageous during speeches on his college campus tour, soberly called the “Dangerous Faggot” tour. Throughout the 2016 election, Yiannopoulos seemed to enjoy nothing quite so much as the crass, antagonistic side of candidate Trump. He didn’t just celebrate it; he rode it like a wave to greater stardom.
Trump’s attacks on the free press don’t just threaten the media—they undermine the public’s capacity to think, act, and defend democracy.
Are Donald Trump’s latest attacks on the press really that bad? Are they that out-of-the-ordinary, given the famous record of complaints nearly all his predecessors have lodged? (Even George Washington had a hostile-press problem.)
Are the bellows of protest from reporters, editors, and others of my press colleagues justified? Or just another sign that the press is nearly as thin-skinned as Trump himself, along with being even less popular?
I could prolong the buildup, but here is the case I’m going to make: Yes, they’re that bad, and worse.
I think Trump’s first month in office, capped by his “enemy of the people” announcement about the press, has been even more ominous and destructive than the Trump of the campaign trail would have prepared us for, which is of course saying something. And his “lying media” campaign matters not only in itself, which it does, but also because it is part of what is effectively an assault by Trump on the fundamentals of democratic governance.
It’s a great physics thought experiment—and an awful accident in 1978.
What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter. Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the universe, colliders have entered the zeitgeist and tapped the wonders and fears of our age.
The Italian philosopher Julius Evola is an unlikely hero for defenders of the “Judeo-Christian West.”
In the summer of 2014, years before he became the White House chief strategist, Steve Bannon gave a lecture via Skype at a conference held inside the Vatican. He spoke about the need to defend the values of the “Judeo-Christian West”—a term he used 11 times—against crony capitalism and libertarian capitalism, secularization, and Islam. He also mentioned the late Julius Evola, a far-right Italian philosopher popular with the American alt-right movement. What he did not mention is that Evola hated not only Jews, but Christianity, too.
References to Evola abounded on websites such as Breitbart News, The Daily Stormer, and AltRight.com well before The New York Timesnoted the Bannon-Evola connection earlier this month. But few have discussed the fundamental oddity of Evola serving as an intellectual inspiration for the alt-right. Yes, the thinker was a virulent anti-Semite and Nazi sympathizer who influenced far-right movements in Italy from the 1950s until his death in 1974, but shouldn’t his contempt for Christianity make him an unlikely hero for those purporting to defend “Judeo-Christian” values?
The preconditions are present in the U.S. today. Here’s the playbook Donald Trump could use to set the country down a path toward illiberalism.
It’s 2021, and President Donald Trump will shortly be sworn in for his second term. The 45th president has visibly aged over the past four years. He rests heavily on his daughter Ivanka’s arm during his infrequent public appearances.
Fortunately for him, he did not need to campaign hard for reelection. His has been a popular presidency: Big tax cuts, big spending, and big deficits have worked their familiar expansive magic. Wages have grown strongly in the Trump years, especially for men without a college degree, even if rising inflation is beginning to bite into the gains. The president’s supporters credit his restrictive immigration policies and his TrumpWorks infrastructure program.

When my wife was struck by mysterious, debilitating symptoms, our trip to the ER revealed the sexism inherent in emergency treatment.
Early on a Wednesday morning, I heard an anguished cry—then silence.
I rushed into the bedroom and watched my wife, Rachel, stumble from the bathroom, doubled over, hugging herself in pain.
“Something’s wrong,” she gasped.
This scared me. Rachel’s not the type to sound the alarm over every pinch or twinge. She cut her finger badly once, when we lived in Iowa City, and joked all the way to Mercy Hospital as the rag wrapped around the wound reddened with her blood. Once, hobbled by a training injury in the days before a marathon, she limped across the finish line anyway.
So when I saw Rachel collapse on our bed, her hands grasping and ungrasping like an infant’s, I called the ambulance. I gave the dispatcher our address, then helped my wife to the bathroom to vomit.
