Can you pass this Turing test?

What did they think about the weather that morning?

Three different responses came from a male human, a female human and a machine. Which is which? Keep in mind that the event was held in October 2008 and they all knew it was autumn/fall in England. The responses were:

A.”I do tend to like a nice foggy morning, as it adds a certain mystery.”
B. “Not the best, expecting pirates to come out of the fog.”
C. “The weather is not nice at the moment, unless you like fog.”
So which is which?

That is from a paper by Kevin Warwick, “Not Another Look at the Turing Test.”  I will offer the answer when I get back home.  For the pointer I thank Michelle Dawson.

Has India solved the problem of banking regulation?

Forget Glass-Steagall:

The branches are run almost entirely by and for the children, with account holders electing two volunteer managers from the group every six months.

“Children who make money by begging or selling drugs are not allowed to open an account. This bank is only for children who believe in hard work,” said Karan, a 14-year-old “manager”.

During the day, Karan earns a pittance washing up at wedding banquets or other events. In the evening, he sits at his desk to collect money from his friends, update their pass books and close the bank.

“Some account holders want to withdraw their money. I ask them why and give it to them if other children approve. Everyone earns five per cent interest on their savings.”

This system now has over two hundred branches in half a dozen countries.  The article is here, hat tip goes to Kottke.  If I understand the account correctly, it is also run largely by street children.

Manila notes

How the mothers talk to, smile at, and elevate their small children reminds me uncannily of Mexico.  It was actually Mexico, not Spain, that ruled the Philippines for centuries.  You can tell how bad the traffic or the flooding is by the clucking sounds made by the taxi drivers.  There is a lot of boxing on TV, and you will regularly be surprised by which food items turn out to taste the best.  Don’t rule out the baked goods or the chicken minestrone soup.

This is a surrealistic dream country, combining fractured elements of an earlier global economy in strange and unpredictable ways.  If you’re not paying attention you can think you are somewhere else — Acapulco?  Lima?  Los Angeles? but in which years? — and yet you are regularly pulled back to the Filipino reality, if only by seeing the Chinese dragons perched in front of the Spanish colonial church.  “My Favorite Things Filipino” would all be moments of disorientation.  The traditional exotic spots now seem pseudo-exotic to me, at least compared to Manila, which forces you to rethink everywhere else you have visited.

Someone should write a New Yorker article about how Filipinos use music in public spaces.  The mango is superb, even by the standards of tropical countries.  If I lived here, I would learn how to talk with my eyebrows.  They don’t like to criticize each other.  Martha Stewart is brought up and discussed by high status Filipinos without irony.

The ability to appreciate the Philippines is a Turing test of some sort, but I am not yet sure for what.

An event study of ACA winners and losers

I have not had the chance to read through this paper, by Jonathan Hartley, but thought I should pass along the abstract and link:

Abstract:
The Patient Protection and Affordable Care Act of 2010 marked a substantial shift in US healthcare policy. We create an event study observing the returns of healthcare stocks in the S&P 500 when on June 28, 2012 the US Supreme Court very unexpectedly ruled that the individual mandate, a provision requiring that Americans maintain a certain level of health insurance or face a monetary penalty, was not unconstitutional. The paper finds that as a result of the upheaval, over two days following the ruling the cumulative average abnormal return of managed care stocks was -6.7% (equal to -$6.9 bn in market capitalization), while the same metric was -1.2% (-$1.5 bn) for biotechnology companies, 3.2% ($0.4 bn) for hospital firms, 1.9% ($1.6 bn) for healthcare service firms, and 0.5% ($4.8 bn) for pharmaceutical companies. Healthcare equipment, distribution, and technology sub-industry stocks had relatively flat cumulative abnormal returns over the period.

Do those results make you more or less favorable toward ACA?

“Back to the Future of Green Powered Economies”

From Juan Moreno Cruz and M. Scott Taylor:

The purpose of this paper is to introduce the concept of power density [Watts/m²] into economics. By introducing an explicit spatial structure into a simple general equilibrium model we are able to show how the power density of available energy resources determines the extent of energy exploitation, the density of urban agglomerations, and the peak level of income per capita. Using a simple Malthusian model to sort population across geographic space we demonstrate how the density of available energy supplies creates density in energy demands by agglomerating economic activity. We label this result the density-creates-density hypothesis and evaluate it using data from pre and post fossil-fuel England from 1086 to 1801.

Many of you have been asking for more coverage of this topic, so here is a starter.  Ungated copies are here.

What’s with the eurozone update?

A few of you have emailed and asked.  I understand the latest as follows: Draghi basically understands the problem, but is hemmed in by Germany.  He is now to some extent freelancing and daring Germany to pull him back in.  He’ll print money to target short-term yields for the debt of the periphery, which he feels Germany might eventually accept, for lack of better alternatives and because it also keeps up the pressure for policy reforms.  He’s rather audaciously trying to redefine what the ECB’s mandate should be taken to mean by defining a lot of “extracurricular” activity as keeping the system up and running.  He’ll push for the banking license for ESM (which would allow them to significantly expand what they do and in essence bypass some of the charter restrictions on the ECB itself), which he probably feels Germany won’t accept but what the heck he’s gotten this far so why not keep on trying?  It’s easy enough to criticize him for not having made any kind of full commitment, but he’s already played more of a dare game than most observers thought possible.  I say he is doing a high-quality tightrope act which probably will fail but which increases the chance of the whole thing pulling through.

He’s daring the Germans to zap him, knowing he stands some chance of going down in history as the central banker who saved the eurozone, knowing that he has nowhere else to go, knowing the Germans have nowhere else to go, and knowing that he has nothing to lose from being fired or otherwise emasculated.  He also knows he has a lot of other eurozone nations on his side.

Just not the ones who will end up paying the bills.

Brad Plumer adds useful comment with a survey of opinion.

What is a socially optimal level of bike-riding danger?

Maxim Massenkoff writes to me:

You’ve blogged about bike laws before; I have a question about a particular cyclist (me). As bikers go, I’m very considerate. I obey red lights and stop signs. But I’ve noticed that many DC drivers expect me to break the law, eg., if one reaches an intersection a little before me, he’ll often get frustrated when I stop and give him the right-of-way.

This makes me wonder: if my only goal is to save other bikers from injury and death, should I follow or break the rules? Say that right now 50% of bikers break rules and 50% don’t. Then I figure most normal drivers will be cautious and hesitant around bikers. But if only 5% break rules, then cycling for that subset is way more dangerous as drivers will expect law-abiding bikers.

This model is rather simplistic, as it certainly goes both ways–bikers adjust their strategies to the habits of drivers. But we can consider DC and the marginal effect of one additional rule-abiding or rule-breaking cyclist. Which side should I choose, given my selfless utilitarian preferences above?

Dennis Rodman on the Philippines

Apparently, aging former NBA stars do some barnstorming here, as my taxi driver from the airport told me almost immediately upon my arrival in Manila.  From an excellent Grantland article on the topic, no love of sports required, here is one excerpt:

Before tip-off, a sideline reporter snags a short interview with Pippen. “Scottie, what have you heard of the Philippine league?” she asks. “Well, I haven’t heard too much about it.” The moment was a flashback to the unintentional comedy bonanza at the press conference the day before the game, where Pippen & Co. strained to find polite answers to questions like “Besides the Philippines, what other countries have you guys been to?” and “I’m not a press but how is it when you arrive here, how do you feel that you are playing in this country where basketball is one of the popular sports?” Rodman, predictably, punctured the air of false ceremony when he was asked how he found the Philippines on this, his second trip to the country. “The same [as] when I left it,” he said. “You guys still look the same, so what the hell.”

In contrast, I have been here only once.
