Zell Miller is wrong, but he isn’t crazy

Zell Miller got into trouble with the media a few days back when he made the following statement, according to the Atlanta Journal Constitution website: … former U.S. Sen.

U of C economics to pick next faculty member using reality TV?

A news report from thespoof.com: CHICAGO. The University of Chicago, known for its free-market approach to economics, today announced that it will select its next tenured faculty member in the “the dismal science” through a reality TV competition modelled on shows such as “Survivor” and VH1’s “The (White) Rapper Show”. “We’re a competitive bunch,” said department chair Philip Reny, “and . . .

The closest thing I ever had to summer camp

The Chicago Tribune asked me to describe my most memorable summer camp experience. Are you kidding? There was no way in the world that I ever would have gone away to summer camp as a kid. The closest I could come up with was the following story, which my Aunt Liz will appreciate because she just taught my six year . . .

What do Bill Clinton, Murray Gell-Mann, Kareem Abdul-Jabbar, and Emily Oster have in common?

They are all speakers at the TED conference which is being held this week in Monterey, California. As I have written before, TED is perhaps the single most interesting way that a smart and curious person could spend a week. This is the first time Emily Oster, who is a Becker Fellow here at U of C, will be on . . .

Are you as smart as a 7th grader?

There is a new TV show that pits adults against 5th graders. The adults don’t fare so well. But the adults chosen to go on the show are not randomly selected, and the 5th graders are even far less random. Illinois gives a state exam to all 7th graders. Some of the questions are on astronomy. The 7th graders didn’t . . .

Let’s Just Get Rid of Tenure (Including Mine)

If there was ever a time when it made sense for economics professors to be given tenure, that time has surely passed. The same is likely true of other university disciplines, and probably even more true for high-school and elementary school teachers. What does tenure do? It distorts people’s effort so that they face strong incentives early in their career . . .

Tim Harford on Roland Fryer and “Acting White”

The Wall Street Journal on Economists and Autism (and why isn’t the Wall Street Journal free online?)

After Slate wrote about an economics paper alleging a link between TV and autism, I blogged my skepticism regarding the claim. I haven’t seen or heard anything since that time to change my opinion. Yesterday, the Wall Street Journal revisited that paper on autism, but also embedded the discussion into a larger question of whether economists and economic techniques should . . .

The editor of the Journal of Clinical Psychiatry needs to have his head examined

The Journal of Clinical Psychiatry recently published a paper on the relationship between smoking and post-traumatic stress disorder. This newspaper report on the article starts out okay:“Post-trauma mental health disturbances such as post-traumatic stress disorder (PTSD) are associated with increased smoking, either by starting to smoke or an increase of tobacco use,” write Dr Peter G Van der Velden, of . . .

What do Freakonomics and the Dalai Lama have in common?

Until today, I would have been hard-pressed to answer that one. In today’s New York Times “Inside the List” column they give the answer: Freakonomics and the Dalai Lama‘s book “The Art of Happiness” are among the books to stay for the longest period of time on the New York Times bestseller list without ever making it to number 1.

Does Omega-3 Work Miracles?

About twice a year I go on a health kick that lasts a few weeks. Typically this involves going for one-mile runs two or three times, doing as many push-ups as I can (about eight) every night, increasing the fiber in my diet, ramping up my carrot juice consumption, and taking whatever health pill is currently in vogue. I’m right . . .

The war on drugs, tobacco style

What happens when officials decide to ban tobacco inside a prison? Exactly what happens when you ban drugs in the outside world. Here is Gary Becker’s take on the war on drugs, written for a general audience on the Becker-Posner blog. Roland Fryer, Paul Heaton, Kevin Murphy, and I have written an academic article on the impact of crack cocaine. . . .

More Economics Music

This song was written by a procrastinating Econ 101 student: “Girl, Your Marginal Benefit Is Far Greater Than Your Marginal Cost” The tune is quite catchy. If you listen to the lyrics carefully, though, you will see that the singer/songwriter probably should have spent more time studying for the exam and less time writing this great song…the economics concepts described . . .

Sexy Stephen Dubner

My friend Laura Beth Nielsen at the American Bar Foundation has a theory that people who are good at one thing are good at everything. Since she shared it with me, I have thought often about whether it is true. I tend to believe it, with the important qualification that the right kind of practice is critical to being good . . .

A modern interpretation of the apple-orange

Not long ago Dubner blogged about the various knock-offs of the apple-orange concept. Here is one that is a little different — is there perhaps a bit of onion thrown into the mix for good luck? The website must be gettting a lot of traffic because a whole bunch of Freakonomics blog readers have already been in touch to alert . . .

When a gang member runs for alderman

With city elections fast approaching in Chicago, I went looking to find out more about the time that the Gangster Disciples, the biggest gang in Chicago, ran a candidate for alderman. I had always heard about it, but never knew any details. Legend has it that the Chicago police had decided to tolerate the Gangster Disciples, but because they got . . .

Portugal’s abortion ban

A number of Portuguese reporters have contacted me asking my opinion about the nationwide vote to consider whether women in that country should be allowed to have abortions. After some thought, I decided not to reply to any of these press inquiries. The reason is that my research in abortion and crime, as discussed in Freakonomics, is virtually irrelevant to . . .

Not the sort of article you expect an economist to write

Over a decade ago, Swarthmore economist Fred Pryor wrote this fascinating article about reading through the records of the East German secret police who arrested him while he was doing dissertation research in East Germany in the early 1960s. It pales in comparison, but when Sudhir Venkatesh and I were doing research on gangs there was always a lingering concern . . .

At this coffee shop, the coffee is free

An interesting article in the Seattle Times about a coffee shop in Kirkland, Washington. The coffee is free, but only if you are willing to suffer the guilt of not having paid for it and the scorn of other customers. (Hat tip to Jason Kenealey.)

Should Mayor Daley Decree that All Chicago Bears Fans be Happy Tomorrow?

On the first day of class, I tell my undergraduates that if they only learn one thing in my course, I hope that it will be to recognize and appreciate the difference between correlation and causality. Most of the students laugh smugly, thinking they already know the difference. It never ceases to amaze me, however, when a cleverly designed exam . . .

Those Damn Mongolians Are at It Again

When Mark Duggan and I wrote our statistical analysis of match rigging in sumo wrestling (which also was featured in Freakonomics), I spent a lot of time digging through translations of Japanese media reports of suspected past match rigging incidents. Almost every prior accusation of match rigging had a common theme: it was always a foreign sumo wrestler at the . . .

A Final Clue

Tif177 was on the right trail when he/she offered the following guess: the speaker was actually a recorded speech/tape that the organizer played at a faster RPM than originally intended. I am getting on an airplane and will be out of action for the day, so if someone gets the right answer Dubner said he would post a blog entry.

About six months ago I was at a big conference. I was scheduled to present at 2 PM to an audience of 500 or 1,000 people. Another speaker was on from 1 to 2 PM. I told the organizer I would be back by 1:45 PM, leaving plenty of time before I had to hit the stage. At 1:30 I . . .
