Search Giant, Search Thyself

To ward off brain drain, Google has developed an algorithm to determine which employees it most risks losing.




More Good News

Just before Christmas, I reported that the CBOE‘s Volatility Index (^VIX) had fallen from “an apocalyptic 80 percent” to a merely extraordinary 45 percent.
And I said:
When it drops below 30 percent, it will be a strong indication that the market correction is complete and we’re back to business as usual.
Happily, we’re going to get a chance to see if I was right.



When Is a Blank CD Worth $50?

When it’s paired with a book of photographs by filmmaker David Lynch and an invitation to fill the blank CD with tracks from an illegally downloaded album. That’s the weird new distribution scheme being floated by musicians Danger Mouse and Sparklehorse.



Why Finding the Best Isn't Worth It

In the delightfully sophomoric movie Clerks 2, Randal tells Dante, “Odds are there’s someone out there who’s a better match for you than the girl you are about to marry.” Even if Dante engaged in the most thorough possible search for a wife (which he certainly didn’t in the movie), Randal’s statement is correct.



How the O.G.'s Did Business

The We Are Supervision blog has a collection of business cards used by Chicago street gangs during the 1970’s and 1980’s. They are extremely interesting as well as — depending on where you work — extremely NSFW.




The Downside of Sexy Science

A paper by a team of scientists and analysts maps out how fields and subdisciplines emerge in 21st-century science. One of the main findings: much like trendy baby names boom and bust, the most high-influence subdisciplines also tend to be the most short-lived.



We Need Your Questions

In the comments below, please pose some questions that you would like to see answered in the paperback Q&A. They can concern anything you’d like: material in the book, modes of collaboration, the price of tea in China, material in the upcoming SuperFreakonomics, etc. We will probably use 8 or 10 or 15, but the more we have to choose from, the better off we’ll be.



Could Women Have Prevented a Financial Crisis?

The economist Anne Sibert hypothesizes that gender inequality in the finance industry is partly to blame for the financial crisis. She points to evidence that men are less risk-averse in financial decision-making, more overconfident, and perhaps susceptible to testosterone-fueled feedback loops in asset bubbles.



Sir Thomas More: Honorary Economist

My former student Emily Feldman informs me now that even Beccaria was a few hundred years too late. Back in 1516, Sir Thomas More already understood the concept of marginal deterrence.





The Problem With the Save Darfur Coalition

In his new book Saviors and Survivors: Darfur, Politics, and the War on Terror, Mahmood Mamdani “attacks the Save Darfur Coalition as ahistorical and dishonest, and argues that the conflict in Darfur is more about land, power, and the environment than it is directly about race.” Guernica magazine interviewed the controversial author about the historical roots of the Darfur conflict, the similarities between Darfur and Iraq, and the proper role of the International Criminal Court (ICC) in Sudan and elsewhere.




High-Stakes Testing

Each year, a million or so high school students pay $45 for the chance to prove themselves with the College Board’s SAT. A good percentage of those students pay for the College Board’s test prep courses as well. All that testing adds up.




When Airline Tickets Start Looking Like Cigarettes

Cigarettes are some of the most heavily taxed goods around. According to this source, the average state tax per pack of cigarettes is $1.23, plus an additional $1.01 of federal taxes, as well as any local taxes. With an average price per pack in the United States of $4.82, the combined state and federal taxes make up 46 percent of the price. In Chicago, total taxes per pack are a whopping $4.67 per pack! I don’t know the exact price of cigarettes in Chicago, but taxes must be around two thirds of the total cost.



FREAK Shots: A Different Use for Your Picket Fence

This photo, sent to us by blog reader Mike Martin, shows how some residents of Newtown, Australia, deal with their junk mail. The sign says it’s a science experiment, but we’d imagine that impaling your junk mail on a fence can also be highly therapeutic.



What Do 3,000 Years Do to Wages?

One of the better-known biblical passages, Leviticus 27:1-7, lists the value of pledges of silver to the temple based on the value of a person: 50 shekels for a man between the ages of 20 and 60, 30 shekels for a woman of the same age, 15 shekels for a man over 60, and 10 shekels for a woman over 60. Once we ignore differences in labor-force participation, the earnings ratios today are not that far from what was expected 3,000 years ago.



The "We're In The Money" Blues

Listeners of “The Numbers” segment on NPR’s Marketplace, a daily recap of the stock market’s action, thought its upbeat version of “We’re in the Money” as background music is inappropriate for the times.



The Memory Palace

History is full of half-forgotten tales. That time, for instance, when the British thought Ben Franklin was helping the French build a death ray. Or when everyone in the Netherlands accidentally got high for a year on rye bread tainted by a psychedelic mold. Or how a dentist’s visit to Carlsbad Cavern inspired a doomsday weapon that could have ended World War II, if the atom bomb hadn’t done it first. Nate DiMeo has been collecting these stories, in short, wonderful podcasts, on a site called The Memory Palace.




Keeping Your Pints Honest

Oregon’s House recently passed the “Honest Pint Act,” which would allow drinking establishments to display state-issued stickers certifying that their pint glasses actually hold 16 ounces, as opposed to the 13- and 14-ounce glasses that some bars try to pass off as pints.




The Invisible Hand Hoax

In a new paper, Gavin Kennedy argues that Smith actually had no invisible-hand theory, pointing out that the phrase appears only three times in Smith’s writings. One scholar believes that Smith’s use of the phrase was a “mildly ironic joke.”



Want to Fix New York Air Congestion? Shut Down LaGuardia

During a recent ground delay at LaGuardia, I got to talking with an off-duty pilot for a major airline who was extraordinarily knowledgeable about every single airline question I could think to ask him. (With any luck, he’ll soon be joining us here as a guest blogger.) When I asked for his take on New York air congestion, he said the solution was easy: shut down LaGuardia.




C.E.O. Pay: Blame It on the Next Guy

Recent studies suggest that exorbitant C.E.O. compensation isn’t primarily produced by greed or even the need to compensate invaluable talent, but rather firms benchmarking C.E.O. pay against other firms’ pay. That’s what Ray Fisman writes in Slate. One prominent C.E.O.’s raise therefore sends ripples of pay hikes through competing companies.
