*Vortices

VORTICES....Via Mark Kleiman, researchers at the University of Michigan have created a wave-based system for generating electricity called VIVACE, or "vortex-induced vibrations for aquatic clean energy":

The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned horizontal to the water flow and attached to springs. As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity.

....A "field" of cylinders built on the sea bed over a 1km by 1.5km area, and the height of a two-storey house, with a flow of just three knots, could generate enough power for around 100,000 homes....The scientists behind the technology, which has been developed in research funded by the US government, say that generating power in this way would potentially cost only around 3.5p per kilowatt hour, compared to about 4.5p for wind energy and between 10p and 31p for solar power. They say the technology would require up to 50 times less ocean acreage than wave power generation.

...."If we could harness 0.1 per cent of the energy in the ocean, we could support the energy needs of 15 billion people. In the English Channel, for example, there is a very strong current, so you produce a lot of power."

Well, why not? Vortex-induced vibrations generated enough power to destroy the Tacoma Narrows Bridge in 1940, so why not get something useful out of it?

Of course, claims like these pop up constantly, and there's no telling how well VIVACE will work until there's been a real-world test. That will happen next year, when the boffins plan to set up a small prototype in the Detroit River designed to generate 3 kilowatts of power. No word yet on an ocean floor test.

More War

MORE WAR....Bill Kristol has another war he wants us to fight? Count me in! I mean, who wouldn't want to stand on the sidelines and cheer on an invasion promoted by a guy who's been so prescient about the use of American military force?

China's Economy

| Sun Nov. 30, 2008 12:34 PM PST

CHINA'S ECONOMY....The Chinese leadership is worried:

Chinese President Hu Jintao warned at a weekend meeting of the Communist Party's elite Politburo that China is losing its competitive edge as international demand for its products is reduced, according to official state media reports Sunday.

China's growth rate has been forecast to be about 9 percent in 2008, down from 11.9 percent the year before and close to the 8 percent that economists say China must maintain in order to keep the labor market stable.

For more, see Brad Setser's gloss on a recent World Bank report, which suggests that China's actual problems have been domestic up until now (falling wages and tanking real estate investment) but will indeed start to become export based next year. Regardless, the end result is that China will be buying up even more Treasury debt than ever over the next few years. That's probably a good thing in the short term, but not so good in the long term.

Cassandra Update

| Sun Nov. 30, 2008 12:12 PM PST

CASSANDRA UPDATE....Yesterday I asked for names of people who had given early warning of the global financial meltdown. Not just people who foresaw the housing bubble, mind you, but people who figured out some of the other problems that made a bursting housing bubble into a worldwide catastrophe and were banging the drums about them. Unfortunately, nearly all the answers came in one of three buckets: (a) Nouriel Roubini, (b) people warning about the housing bubble, or (c) people writing in 2006 or 2007.

However, there were a few plausible suggestions for analysts whose warnings went beyond the housing bubble and who did it earlier than 2006, including Peter Schiff, Tanta at Calculated Risk, Mish at Global Economic Analysis, Doug Noland at PrudentBear, and Brad Setser. Martin Wolf provides a few more possibilities here. I don't know enough about their early work to say for sure that these folks were all early and accurate critics of more than just the housing bubble, but they seem to be likely suspects.

On the other hand, commenter Commenterlein offers a counterpoint:

Most of the people listed above recognized that there was some form of housing bubble (at least in some markets), but most of them (imho ex-ante correctly) focused on the U.S.' external balance (i.e., current account deficit) as the main problem. Hence the crisis most economists predicted was a rapid depreciation of the dollar, associated with a massive and pain-full shift of employment from the non-tradeable sectors (i.e., housing) to the tradeable ones.

Bottom line: I have not yet found anyone who predicted that a house price decline would lead to a complete loss of confidence in the financial sector and a massive credit crunch taking down institutions all over the world with essentially no (direct) exposure to the US housing market. And as much as I love Roubini, perpetually predicting the end of the world for ever changing reasons just isn't that useful.

The current account deficit was, of course, a routine topic of concern among economists, but as Commenterlein points out, a dollar depreciation crisis isn't the crisis we actually got. In fact, just the opposite: we're practically in a T-bill bubble right now. That may yet change, causing us even more problems, but so far lack of demand for U.S. debt from the Chinese or anyone else just hasn't been a factor in the world's financial problems.

Tell you what, though: let me ask a much simpler question, since asking "who got it right?" is obviously a little tricky. Back in April 2004 the SEC voted to loosen the capital rules for the five biggest Wall Street investment banks. In retrospect, this was a very bad idea indeed, and it was a bad idea for precisely the reasons that have caused our financial problems to become so dire: it allowed leverage to skyrocket unsustainably and lending standards to deteriorate.

So here's my question: Did anyone object to this at the time? The New York Times identified one person who objected, an Indiana consultant named Leonard Bole, and one SEC commissioner who at least asked questions, Harvey Goldschmid, but that's it. Anyone else? This may have been an obscure ruling to people like you and me, but I'll bet it wasn't all that obscure to people who follow Wall Street closely, and I figure anyone who truly knew what was coming would have sounded a warning about it in 2004 or 2005. Did anyone?

UPDATE: In comments, Ole nominates fellow Dane Jakob Brøchner Madsen, who, according to a Google translation of epn.dk, "has been proclaimed the country's most pessimistic economist." However, even Madsen admits, "I knew well that the system was rotten. But not that it was so rotten."

Outliers

| Sun Nov. 30, 2008 10:46 AM PST

OUTLIERS....Should I pick up a copy of Malcolm Gladwell's Outliers and give it a read? I'm sort of disinclined to for two reasons. First, I read Blink this year and was surprised at how bad a book it was. Even at a slim 200 pages, I'd say that a good half of it was unrelated to its putative subject. Second, I gather that the subject of Outliers is that there's a considerable amount of luck involved in becoming successful. But is that something that really needs an entire popular book? It seems like one of those topics that's so obviously true that it hardly bears a detailed dissection.

But then again, maybe it's not quite so obvious as I think. Has anybody read it? Do you recommend it, maybe as something to put on my Christmas list?

Searching for Cassandras

| Sat Nov. 29, 2008 12:56 PM PST

SEARCHING FOR CASSANDRAS....Brad DeLong says he was keenly aware of the housing bubble and fully expected it to burst. Me too! But he didn't expect any of the following:

(3) the discovery that banks and mortgage companies had made no provision for how the loans they made would be renegotiated or serviced in the event of a housing-price downturn.

(4) the discovery that the rating agencies had failed in their assessment of lower-tail risk to make the standard analytical judgment: that when things get really bad all correlations go to one.

(5) the fact that highly-leveraged banks working on the originate-and-distribute model of mortgage securitization had originated but had not distributed: that they had held on to much too much of the risks that they were supposed to find other people to handle.

(6) the panic flight from all risky assets — not just mortgages — upon the discovery of the problems in the mortgage market.

(7) the engagement in regulatory arbitrage which had left major banks even more highly leveraged than I had thought possible.

(8) the failure of highly-leveraged financial institutions to have backup plans for recapitalization in place in the case of a major financial crisis.

(9) the Bush administration's sticking to a private-sector solution for the crisis for months after it had become clear that such a solution was no longer viable.

So then: who did expect any/all of this stuff? Commenter macheath offers a few heroes:

Some people saw pieces of it, but were largely ignored or marginalized. Dean Baker was hammering on the house price bubble for years, and several people (including Gary Gensler at Treasury) called for stronger capitalization of Fannie and Freddie, saying their business model was not sustainable, and they were beaten up by Congress, Democrats and Republicans alike. Brooksley Born at the CFTC wanted to start investigating derivatives in the mid-1990s, and was slapped down by Greenspan, Rubin, and Summers, leading to legislation (backed by Summers) to prohibit the CFTC from regulating derivatives.

Is that it? Was anyone else warning us about Brad's seven points back in 2004? Or 2005?

Climate Change in the Himalayas

| Sat Nov. 29, 2008 12:14 PM PST

CLIMATE CHANGE IN THE HIMALAYAS....Joe Romm passes along the news today that Himalayan glaciers are melting faster than anyone has previously predicted. You can add this to Romm's list of other climate change impacts that are happening faster than most climate models predict, including the canonical IPCC models:

This is why climate scientists have been running around with their hair on fire for the past couple of years. It would be nice to think that perhaps our current climate models are too pessimistic; or even that they're right but maybe we'll end up at the low end of the predicted warming ranges; or at worst that the models are right and we'll end up right at the center. But that just doesn't seem to be the case. What it really looks like is that our current models aren't pessimistic enough and that the growth in greenhouse gas emissions is exceeding even the modelers' highest estimates. We are fast approaching a point of no return that will likely kill hundreds of millions of people, destroy much of the world's food supply, and spark resource wars that make Rwanda look like a mild family quarrel. More from Romm here and here on what's happening and what to do about it.

Quote of the Day - 11.29.08

| Sat Nov. 29, 2008 9:53 AM PST

QUOTE OF THE DAY....From Emile Earles, a Cadillac owner in West Point, Georgia, on buying American:

"You can only be patriotic until you can't afford it anymore."

And this riposte from Eddie Striblin, a salesman at the local GM dealership:

"Let me ask you a question: You ever heard of anybody braggin' on a '57 Honda?"

That's the American car industry in a nutshell, isn't it?

*Chart of the Day - 11.27.2008

| Fri Nov. 28, 2008 8:04 PM PST

CHART OF THE DAY....Via Overcoming Bias, three French researchers surveyed 1,540 people and offered them the opportunity to play a game in which a coin is tossed ten times and they'll win ten euros each time it comes up heads. "The participant is then asked for his/her own estimation, according to his/her experience and his/her luck, of the number of times heads will occur, i.e. how many times (out of ten) he/she thinks he/she is going to win (and get 10 euros)." What do you think is the most terrifying aspect of this survey?

  1. The mean answer was 3.9.

  2. About ten people thought they would win every single toss.

  3. The authors managed to produce a 21-page paper out of this.

The full survey is here. The authors also note that women are more pessimistic than men; old people are more pessimistic than young; and that nearly everyone answers "five" if monetary gain is removed from the question. In other words, people seem to know the odds, they just think the universe is stacked against them. (Or that the researchers are going to cheat. Take your pick.)

The exception, of course, is those ten respondents who think they'll win every time. Here in America, we call those people "investment bankers."

Patching Things Up

| Fri Nov. 28, 2008 3:45 PM PST

PATCHING THINGS UP....Samantha Power, last heard from calling Hillary Clinton a "monster" and then apologizing fulsomely for it, is back:

State Department officials said Friday that Samantha Power is among a group of foreign policy experts that the president-elect's office selected to help the incoming administration prepare for Clinton's anticipated nomination as secretary of state.

....Clinton's office declined to comment on Power's inclusion in the State Department transition, but an official close to the Obama transition team said Power had ''made a gesture to bury the hatchet'' with Clinton and that it had been well-received.

If we accept the conventional wisdom that Obama's choice of Clinton as Secretary of State is a generous gesture meant to help unify the party, then there would be few more forthright ways for Clinton to reciprocate than by nominating Power for some kind of meaningful position at Foggy Bottom. It would be a good sign that those hatchets have been well and truly buried.
