In theory the mechanism is really quite simple:
1. A sensor detects the rumblings of an earthquake.
2. Within .5 to 1 second an air tank pushes air in-between an artificial foundation and the actual structure of the home, lifting it as high as 3cm off the ground.
3. While the earth below violently shakes, the levitating home quietly and patiently waits, returning back to the ground once the tectonic plates have settled.
There are pictures and videos at the link, and the company claims it is implementing the idea at 88 sites. The final video is especially fine.
Can you buy health care the way you buy goods and services on eBay? Almost. A small, emerging online service called MediBid is letting providers bid to provide the care that patients need.
Patients must be able to pay cash. They fill out medical questionnaires; they can upload their medical records; and they can request the procedure they need. The patient’s identity is kept confidential until a transaction is consummated. MediBid-affiliated physicians and other medical providers respond by submitting competitive bids for the requested care.
Business at the site is growing.

More at God Plays Dice. I recall a JEP piece (?) many years ago which used the same idea to explain the “road curse”–given two equally good roads most people will always choose the more crowded!
The pinnacle of Asma’s international media charm offensive was a gushing piece in last March’s American Vogue, just before the Syrian uprising began and was met with a crackdown. The article has now mysteriously disappeared from the magazine’s website. Described as a “rose in the desert”, “the freshest and most magnetic of first ladies”, Asma, dressed in jeans, heels and a T-shirt with “Happiness” emblazoned on the back, describes how her home, a triplex apartment, is run “on wildly democratic principles” – seemingly far from the brutal one-party state oppression going on outside.
Looking at her three children, she says: “We all vote on what we want, and where.” Pointing to the dining room chandelier, which is constructed from cut-out comic books, she says: “They outvoted us three to two on that.” Against a backdrop of designer bags, private jets and SUVs, Asma tells Vogue her “central mission” is “to change the mind-set of 6 million Syrians under 18”, encourage them to engage in what she calls “active citizenship.”
The confirmation that senior Haitian officials hold foreign nationality lends growing credence to a leading senator’s charge that Haitian President Michel Martelly is a U.S. citizen and hence illegally in power.
Two weeks ago, Sen. Moïse Jean Charles submitted what he called “irrefutable” evidence to a special Senate Select Committee that Martelly and 38 other high government officials hold dual, and sometimes triple, nationalities.
On Jan. 24, Sen. Joseph Lambert, the Commission’s president, announced in a press conference that the Commission has confirmed dual nationality for two of the 10 cases it has investigated to date. However, Lambert has so far refused to release the names of dual citizenship officials, saying his commission would proceed “impartially” and “without emotion.” He said arrangements have been made to continue the nationality investigations overseas.
The Senate inquiry threatens to create a political crisis which may force President Martelly, his Prime Minister Garry Conille, and other ministers to step down. If the charges against him prove true, it means that candidate Martelly lied to election officials about holding dual citizenship, which current Haitian law explicitly forbids for a high elected official.
Here is more. There is the small matter of the Haitian constitution:
Commission member Sen. Steven Irvenson Benoît said that Haiti’s 1987 Constitution prohibits any foreign national not only from becoming president or prime minister, but also from acting as a minister or secretary of state. The Constitution’s Article 56 stipulates: “An alien may be expelled from the territory of the Republic if he becomes involved in the political life of the country, or in cases determined by law.“
Michel Martelly (“Sweet Mickey”) spent so much time in the United States, often giving concerts, that for years I simply assumed he held dual citizenship. Until recently, I had not known about this provision of the Haitian constitution. What is the old Haitian saying?:
“The constitution is paper, the bayonet is steel.”
Or something like that.
The French village of Courbefy, in Limousin, a region in central France, has been put up for sale for the seemingly low asking price of $436,370, according to the Telegraph. The village, which includes 19 buildings and a swimming pool, was once home to about 200 people. But after the town failed to transform itself into a tourist destination, local residents say it’s now filled mostly with “thieves, drunks and squatters.”
But Courbefy isn’t the only town to go up for sale recently. Last April, a medieval village in the central Italian region of Abruzzo was put up for sale for about $770,000, according to a separate Telegraph report. The village, which is largely uninhabitable, includes 11 “crumbling stone buildings” and a half-ruined 13th century church. More recently, the British village of Askham Richard near York, went up for sale with a price tag of more than $10 million.
Seven studies using experimental and naturalistic methods reveal that upper-class individuals behave more unethically than lower-class individuals. In studies 1 and 2, upper-class individuals were more likely to break the law while driving, relative to lower-class individuals. In follow-up laboratory studies, upper-class individuals were more likely to exhibit unethical decision-making tendencies (study 3), take valued goods from others (study 4), lie in a negotiation (study 5), cheat to increase their chances of winning a prize (study 6), and endorse unethical behavior at work (study 7) than were lower-class individuals. Mediator and moderator data demonstrated that upper-class individuals’ unethical tendencies are accounted for, in part, by their more favorable attitudes toward greed.
That is an abstract from Paul K. Piff, Daniel M. Stancato, Stephane Coté, Rodolfo Mendoza-Denton, and Dacher Keltner. There is a gated version of the paper here, a Wired summary here. Dozens of other sources covered the paper on-line but virtually all fell afoul of mood affiliation (something is wrong with the wealthy and here is a chance to disapprove of them), and a very large number made the subtle shift from “upper class” to “wealthy,” which of course is not the same.
We need to be cautious in our interpretation of these results. Of the seven tests, two of them showed that people driving more expensive cars are more in a hurry and more likely to cut off others or not yield. That’s not praiseworthy, but hardly a major moral condemnation. Several of the tests involved people being asked to imagine they were high class, not actual “high class” people themselves. To that extent we are testing the lower class view of the upper classes, noting that I would not use those terms as given. One of the tests showed that social class did not matter once we adjust for a person’s attitude toward greed. A positive attitude toward greed is positively correlated with social class, but it was also easy enough to “prime” the lower class individuals to feel the same way, suggesting that extreme context dependence will hold here.
Let’s view these results in light of the literature as a whole (I haven’t seen any journalistic source do this). Very often in studies the highest trust, lowest corruption societies in the world are the relatively wealthy Nordic countries, not poor countries. There is plenty of evidence that it is low and falling incomes — not wealth — which helped to explain voter support for fascism. Consumers are eager to buy products from companies such as Apple, and they regard the wealth of the shareholders, and the high profit margins, as a sign they will get a high quality product, not a reason to fear a rip-off. (Can you think of many cases where consumers deliberately seek out lower-class suppliers to minimize the chance of rip-off?) The work of Garett Jones shows that high IQ predicts greater cooperativeness.
That all said, allow me to speculate. If I were playing bridge, and my opponents were wealthy, I really would expect them to cheat more, say with regard to the exchange of illegal cues between partners. For one thing cheating requires some smarts and for another it requires some confidence that it can lead to victory. I expect Vlade Divac to flop more to draw a foul, or expect Kobe Bryant to work harder to manipulate a referee, than I would expect from a lower-status rookie player.
One simple hypothesis — which for now I will take as the default, when you sum up all the evidence — is that high-status people cheat more at games and less at many other activities, including those of real life. (They are also in more of a hurry on the road.) That’s very different than how this paper is being reported, and it’s also a much more interesting hypothesis.

That is from Spencer England of Spencer England’s Equity Review. He writes to me:
I think a major reason for the difference between net and gross investment is the growing share of Info Tech (IT) in business fixed investment. IT now accounts for over half of real business investment. But IT has a much shorter life span than traditional business equipment or investment in structures.
It is like going up a down escalator –you have to run harder just to stay even.
Here is a previous post on the investment drought, with another good picture. Karl Smith offers some related remarks, though I do not focus on transportation as he does, rather given his framing I would put more emphasis on our inability to replace industrialization with something comparably important.
There is a new and excellent paper by Uri Gneezy, John List, and Michael K. Price (gated version here, $5 charge for non-university readers), here is one good excerpt:
…in the automobile repair market, we find that the disabled receive offers that are 30 percent higher than the offers received by the abled. One possible reason for this disparate treatment is search cost differences — one would expect search to be more costly for the disabled. Under this scenario, such agents might search less and repairmen might capitalize on that fact. To test this conjecture, and identify the underlying nature of discrimination, we employ a complementary field experiment where during the offer process all agents note that “I am getting a few price quotes.” Upon having our agents make this simple statement, we find that offer distributions become isomorphic.
The paper has much more of interest.
A friend and I met up at a new bookstore and café in the centre of town, which has only been open for a month. The establishment is in the center of an area filled with bars, and the owner decided the neighborhood could use a place for people to convene and talk without having to drink alcohol and listen to loud music. After we sat down, we asked the waitress for a coffee. She thanked us for our order and immediately turned and walked out the front door. My friend explained that the owner of the bookstore/café couldn’t get a license to provide coffee. She had tried to just buy a coffee machine and give the coffee away for free, thinking that lingering patrons would boost book sales. However, giving away coffee was illegal as well. Instead, the owner had to strike a deal with a bar across the street, whereby they make the coffee and the waitress spends all day shuttling between the bar and the bookstore/café. My friend also explained to me that books could not be purchased at the bookstore, as it was after 18h and it is illegal to sell books in Greece beyond that hour. I was in a bookstore/café that could neither sell books nor make coffee.
In my 2008 post, Interpreting the Monetary Base Under the New Monetary Regime, I argued that the massive increase in bank reserves was neither a necessary harbinger of inflation (as people on the right feared) nor a sure sign of a liquidity trap (as people on the left claimed) but rather represented, at least in part, a sensible aspect of the new regime of paying interest on reserves. I wrote:
When no interest was paid on reserves banks tried to hold as few as possible. But during the day the banks needed reserves – of which there were only $40 billion or so – to fund trillions of dollars worth of intraday payments. As a result, there was typically a daily shortage of reserves which the Fed made up for by extending hundreds of billions of dollars worth of daylight credit. Thus, in essence, the banks used to inhale credit during the day – puffing up like a bullfrog – only to exhale at night. (But note that our stats on the monetary base only measured the bullfrog at night.)
Today, the banks are no longer in bullfrog mode. The Fed is paying interest on reserves and they are paying at a rate which is high enough so that the banks have plenty of reserves on hand during the day and they keep those reserves at night. Thus, all that has really happened – as far as the monetary base statistic is concerned – is that we have replaced daylight credit with excess reserves held around the clock.
A post today at Liberty Street Economics, the blog of the New York Federal Reserve illustrates and explains how the excess reserves have reduced transaction costs in the payment system and risk to the Federal Reserve.
The last chart shows the level of intraday credit extended by the Federal Reserve to Fedwire participants, measured as the daily maximum amount extended by the Federal Reserve. There has been a dramatic decline in the amount of credit extended since the expansion of reserve balances in October 2008. The reduced level of daylight credit has the benefit of reducing the risk exposure of Federal Reserve Banks, as well as the Federal Deposit Insurance Corporation’s (FDIC) fund. Indeed, the expected losses to that fund would be greater if some of the assets of a failed bank had been pledged to a Federal Reserve Bank to collateralize a daylight overdraft, as the collateral would not be available to pay other creditors of the bank. With a greater amount of reserves in the system, banks largely “prepay” for their liquidity needs by maintaining large reserve balances with which to fund their outgoing payments.
