Video We’ve written about the putative deterrent effect of capital punishment both in “Freakonomics,” and here on the blog. But none of those explanations were delivered by our International Video Woman of Mystery (known to her friends, natch, as Ivwom), whom you first encountered in a video last week about sport and violence.
Levitt’s take on the current crime stats for the five largest U.S. cities
A landmark study has been published by Northwestern statistics professor Bruce Spencer offering statistical and empirical data on the accuracy of U.S. jury verdicts. His method involved comparing the decision of a jury with the decision of the judge hearing the case, accomplished by having the judge fill out a questionnaire during jury deliberations. The data pool consisted of 290 . . .
A while ago Levitt posed the question of whether the name of a street (such as “Pleasant Avenue” or “Massacre Lane”) could have an effect on the price of its real estate. Now, it turns out, there’s more data on the subject: The Edmonton Journal reports that a study by a Canadian real-estate analyst found a “a small but noteworthy . . .
After misinterpreting the data on the side-impact crash tests it ran on child car seats, Consumer Reports is changing its methodology on such tests, enlisting the help of experts in the field instead of acting with total independence. (Here is our earlier take on child car seats.)
In the U.K., there are plans afoot to charge a higher fee to park a larger car, even in your own driveway. Remember Swivel, the data mashup site we blogged about? Here’s another new data visualization site, called ManyEyes, run by IBM’s Visual Communications Lab. And here’s a thoughtful review of ManyEyes vs. Swivel. Standardized test scores in Illinois are . . .
We are very fortunate to get some incredibly interesting and perceptive mail from readers. Occasionally, we share these queries (like here and here). We also get some hardcore snark, and we sometimes share those too (like this recent one). An e-mail that showed up the other day was so interesting that I wrote back to ask if I could simply . . .
Redfin is a discount real estate brokerage in Seattle that has put together some interesting data analysis from their first year in business. Their numbers suggest that clients who use their discount brokerage firm pay a lower percent of the list price than the typical home buyer in Seattle (99.329% of the listing price with Redfin vs. 100.233% with other . . .
Michael Lewis writes in today’s New York Times Sunday Magazine about Mike Leach, the innovative coach of the Texas Tech football team. As Lewis describes it, Leach takes a totally different view of football and is on the cusp of revolutionizing the game. It is a very interesting article, and beautifully written. As usual with Michael Lewis, there is a . . .
Po Bronson is, among other things, the author of five books. The first two were novels. The third, The Nudist on the Late Shift, was a rat-a-tat chronicle of Silicon Valley during its most chaotic and muscular era. His fourth book became a big best-seller; it’s called What Should I Do With My Life? and constitutes many different chapters on . . .
According to this article in Wired, a man named Dean Oliver is trying to do for basketball what Bill James and Billy Beane did for baseball: create and exploit new metrics in order to better distinguish players who win from those who simply generate gaudy traditional stats. The Wired article is written by Hugo Lindgren, who is in some measure . . .
Read what Chris Lightfoot has to say about this question here. The origin of the idea for the analysis appears to be in this marginalrevolution post. The idea is that large differences in prices for one-way trips from Detroit to Las Vegas compared to one-way trips the other direction reflects differential migration. The answers aren’t so surprising: the flow tends . . .
I’m undertaking a project on poker. I’ve set up a website, www.pokernomics.com, for people to download their hand histories. Using these hands, I hope to study what differentiates good and bad poker players. The response has been overwhelming. I think we’ve got over 7 million poker hands already. (For those of you who sent hands, but don’t have your Freakonomics . . .
Here’s what I wrote a few weeks ago, just as we embarked on a short California book tour: Earlier in this space we asked if book ads work; now we are led to the next obvious question: how about the author’s tour? Can it possibly be worth all the money and time it takes to fly two people across the . . .
The July 10, 2005, Freakonomics column, “The Seat-Belt Solution: How Much Good Do Car Seats Do?” is about the efficacy of child car seats versus plain old seat belts. This blog post supplies additional research material.
Things move quickly in the modern world. Within two hours of posting my academic paper on car seats vs. seat belts on the Freakonomics web page (the first time this paper had seen light of day), another economist found the paper and tested its hypotheses on a very different data set and reported back the results. The economist is Paul . . .
