"Unbranding" in the Arizona GOP

We recently took note of the “unbranding” movement, in which Firm A might seem to damage Firm B by sending Firm B’s product to an undesirable endorser. The example of the day was Snooki and her Gucci purse. There would seem to be no limit to the unbranding opportunities in the modern world. How about, say, politics? The Times headline says it all – “Republican Runs Street People on Green Ticket” — but Marc Lacey’s article is well worth a read.



Freakonomics: The Movie Out Today on iTunes Only

The Freakonomics movie that premiered this spring at the Tribeca Film Festival is released to the public today — but only on iTunes (and on some Video on Demand cable systems), nearly a month before it hits theaters.



Gold's Magic Price

We’ve had some old unwanted gold jewelry lying around for a long time. With gold at $1,237 per ounce, we figured it was time to sell it. We are a living movement up the supply curve of gold.



How Panhandlers Spend Money

A reporter for the Canadian newspaper The Star handed out five pre-paid credit cards to panhandlers, asked the panhandlers to return the card when finished, and tracked their purchases.



Grumpy Old Men?

New research indicates that older people are “more likely to choose to read negative articles about those younger than themselves. They also tended to show less interest in articles about older people, whether negative or positive.”



Quotes Uncovered: Memorable Movie Lines

Two years ago, I asked for suggestions for the most memorable movie lines of recent years, to help with the next edition of The Yale Book of Quotations. Let me repeat my “bleg” from that time, and ask again for suggestions



The Malaria Wars: Sonia Shah Answers Your Malaria Questions

We recently solicited your questions for Sonia Shah, author of The Fever: How Malaria Has Ruled Humankind for 500,000 Years. Her responses cover the effect of Rachel Carson and Silent Spring on malaria; bed nets and their alternatives; and the history of malaria in the U.S. Thanks to Sonia and everyone who participated.



Drunk or Sober? Harder to Tell Than You Think

A new literature review, summarized in the BPS Research Digest, concludes that “the vast majority of studies find that lay people, police officers and bartenders are in fact hopeless at distinguishing a drunk person from a sober one, at least at moderate levels of intoxication.”



When the Prediction Fits the Crime

It’s not quite Minority Report, but the L.A. Times reports that the LAPD is working with UCLA mathematicians to pursue a sophisticated form of predictive policing.



Is Your University Complying With the New Textbook Law?

University students are returning to campuses throughout the country. It is a migration that raises my spirits – seeing the energetic, eager faces tackling another course in contracts or intellectual property. But this year something is different. For the first time, a federal law has taken effect which requires “institution of higher education receiving Federal financial assistance” to provide students with information on textbook pricing.




SuperFreakonomics Book Club: Ian Horsley Answers Your Questions About the Terrorist Algorithm

In the SuperFreakonomics Virtual Book Club, we invite readers to ask questions of some of the researchers and other characters in our book. Last week, we opened up the questioning for “Ian Horsley,” a banker who’s been working with Steve Levitt to develop an algorithm to catch terrorists. His answers are below. Thanks to Ian and to all of you for the questions.



How to Tell When a CEO Is Lying

In a nifty piece of forensic analysis, two researchers claim to have figured out how to tell when executives are lying. David Larcker and Anastasia Zakolyukina analyzed 30,000 conference calls between 2003 and 2007 to see if certain “tells” during the call were associated with earnings that were later “materially restated.”




Separating Markets

My son is renting a car in December. He’ll drive it for two days in Orlando, then he’ll drive to South Florida for an eight-day stay. With the drop-off charge, the price is $900. But if he drops the car off in South Florida when he arrives and rents a new one from the same company, the total price is only $500. He values his time spent dropping off the car at less than $400, so he’ll do it.



Sesame Street, Nigerian Style

hildren in Nigeria will soon have a new TV option. Sesame Square, a local version of Sesame Street voiced and produced by Nigerians (and funded by a grant from USAID), will “focus on the same challenges faced by children in a country where many have to work instead of going to school: AIDS, malaria nets, gender equality – and yams, a staple of Nigerian meals.”



Power Corrupts

About a month ago, Lincoln announced that it will be introducing a new hybrid electric version of the MKZ model with a price tag of $35,180. On its own this is nothing earthshattering, as many automakers have joined, or will soon join, Honda and Toyota in mass-marketing hybrids. But what makes Lincoln’s announcement exciting is that their hybrid will be coming at a price you won’t be able to refuse. Or will you?



Global Warming Vs. Street Crime

In the Wall Street Journal, Jean Guerrero writes an interesting article about how cities are fighting street crime by the simple act of leaving the lights on deeper into the night. (Other cities have tried Barry Manilow music, with some success.) But leaving the lights on all night doesn’t always jibe with a city’s budget plans — or its global-warming conscience.



The Difference Between Americans and Humans?

The academic psychologist Joseph Henrich brought the Ultimatum game to the Amazon jungle, and found that the Maschiguenga people of southeastern Peru make decisions like economists.



Copyrighting Fashion: Who Gains?

Kal Raustiala, a professor at UCLA Law School and the UCLA International Institute, and Chris Sprigman, a professor at the University of Virginia Law School, are experts in counterfeiting and intellectual property. They have been guest-blogging for us about copyright issues. Today, they write about new efforts to extend copyright law to the fashion industry.



Can iPads Help Stop Sumo Corruption?

The Japan Sumo Association is handing out free iPads to training stables to encourage the use of email. The hope is that the devices will speed up communication between wrestlers, coaches and the association and create a “paper trail” for future scandal investigations.




Renting Wombs in India

Slate takes a look at India’s half-billion-dollar-a-year reproductive-tourism industry. “The primary appeal of India is that it is cheap, hardly regulated, and relatively safe,” writes Amana Fontanella-Khan. “Surrogacy can cost up to $100,000 in the United States, while many Indian clinics charge $22,000 or less. Very few questions are asked. Same-sex couples, single parents and even busy women who just don’t have time to give birth are welcomed by doctors.”



Ticketfree Responds

I received the following email from Kyle Tower, one of the lead members of the Ticketfree team, responding to my earlier post on speeding insurance.



The Biodiversity Card

Until 1985, the word “biodiversity” didn’t exist. Today, it’s fundamental to the grammar of environmentalism. Lamentations about “declining biodiversity,” the “threat to biodiversity,” or the “the biodiversity crisis” comprise the lingua franca of ecological discourse. But it’s worth asking: what are we really talking about when we talk about biodiversity?



Trader Joe's Secrets

Regular readers of this blog will be familiar with Trader Joe’s unexpected owners: a German discount-grocery chain. A new article in Fortune aims to reveal a few more Trader Joe’s secrets.



Do Hurricanes Prefer Cities?

A new study argues that the moisture levels and landscapes of cities influence hurricane movements. Professor Johnny Chan’s research team claims that “cities impose greater friction on the swirling flow because of the tall buildings . . . tropical cyclones tend to be ‘attracted’ towards areas of higher friction.”



When a Changing Labor Market Changes Business

There are innumerable great examples of goods in related markets. And of complements and substitutes. (One of my favorites is the local store that sold rock music and condoms, clearly complements.) It’s harder to cook up neat examples of goods markets that are impinged upon by labor-market changes.



Urban Planning, Animal Style

Southern Sudan recently unveiled plans to remake its ten state capitals, with an interesting twist: “The $10.1 billion plan proposes remaking cities in Sudan’s south into shapes found on regional flags. Blueprints and maps illustrate Juba in the shape of a rhinoceros, Yambio fashioned after a pineapple and Wau as a giraffe.”

Malaria has been infecting and killing humans for many millennia, yet it continues to elude man’s efforts to control it. Sonia Shah’s fascinating new book, The Fever: How Malaria Has Ruled Humankind for 500,000 Years, describes our long relationship with the disease. Shah has agreed to answer your questions so fire away.
