The Supreme Court recently struck down the gun ban in Washington, D.C. A similar gun ban in Chicago may be the next to go. The primary rationale for these gun bans is to lower crime. Do they actually work? There is remarkably little academic research that directly answers this question, but there is some indirect evidence. Let’s start with the . . .
Photo: Rhett Redelings On a recent United Airlines flight I was surprised to see that their new planes are equipped not just with lap belts, but shoulder restraints as well. This just cannot make any sense. First, planes virtually never crash. Second, when they do crash, it is unlikely that a shoulder restraint will be the deciding factor in whether . . .
Hats off to economist Roland Fryer, Joel Klein, the rest of the folks in the New York City Department of Education, and Droga5 for taking home the Titanium Lion prize at the Cannes Lions advertising festival for their work on “Million.” Million is the innovative NYC schools program that puts a specially designed cellphone into the hands of every NYC . . .
There is a mini-controversy on the University of Chicago campus surrounding the announcement of plans to raise money for a Milton Friedman Institute here at the university. Some non-economists are concerned that the Friedman Institute will push a right-wing agenda and tarnish the reputation of the university. Some who knew Friedman well have the opposite worry: that the Institute won’t . . .
We’ve blogged a few times about Zillow (here and here), a website that is trying to shake up the real estate industry. I’ve made radical predictions about the future of the real estate industry. I’m hoping that Zillow will help make those prophesies come true. So to do my part (and because I am as susceptible to flattery as the . . .
When I first stumbled onto the name voyager at the Baby Name Wizard a few years back, I felt like I was seeing the future. It was the sort of web tool that folks dream about. I had exactly the same feeling when I recently visited Gapminder.org. They have an interactive data tool called “gapminder world” that is truly remarkable . . .
People who make millions of dollars doing one thing often come to view themselves as being experts in subjects far afield from those in which they made their wealth. Because they have so much money, others tend to humor them and tell them they are brilliant in the hopes of currying favor, so they don’t get realistic feedback. (The same . . .
Many people know about the World Series of Poker from the television coverage on ESPN. Mostly they just show the “Main Event” on TV. Hoa Nguyen from worldseriesofpoker.com. The main event has a $10,000 buy-in and lasts for two weeks. Leading up to the main event, there are dozens of other tournaments, some of which are going on right now. . . .
I just ran my horse racing model for the Belmont Stakes. It predicts that Big Brown will go off at odds of 1/5…even lower than his morning line odds of 2/5. I estimate that a $2 bet on Big Brown has an expected value of $1.81. Although the expected value is negative (you will lose an average of 19 cents . . .
If your eBay user name is lpinok, then the answer is $55.71. This seems to defy all logic. The item description is: “Just a $50 gift card to Target … .” Why would anyone pay more than face value? (Hat tip: David Hansen)
My father has a lot of ideas. Some of them are pretty good. Others get me into a lot of trouble. Back in July of 2005, my dad had an idea I thought was interesting enough that I passed it along to the staff of Barack Obama. This is well before Obama was running for president — back when he . . .
I love to read books written by police officers about being police officers, and books written by criminals about being criminals. In the latter category, I highly recommend Brutal by Kevin Weeks and Phyllis Karas. Kevin Weeks was Whitey Bulger‘s right-hand man. He is loyal, loves to punch people in the face, and doesn’t mind committing the occasional murder. It . . .
A few years back Dubner and I wrote a piece on Slate heralding a remarkable young economist, Emily Oster. She has continued to do great work. She also has done something incredibly rare for an academic economist: she has admitted she was wrong. In places like India and China, there are many “missing women.” In other words, the sex ratios . . .
A recent Lancet article argued that obesity is contributing to global warming because the obese consume more calories. Since making food releases carbon, that means an obese person, on average, is worse for global warming than a skinny person. (Not to mention the extra methane the obese might release, but that is my father’s area of expertise, not my own.) . . .
Inequality is growing in the United States. The data say so. Knowledgeable experts like Ben Bernanke say so. Ask just about any economist and they will agree. (They may or may not think growing inequality is a problem, but they will acknowledge that there has been a sharp increase in inequality.) Photo: Jim, Wal-Mart Supercenter in Suwanee, Georgia. According to . . .
The breakdown of Eight Belles in this year’s Kentucky Derby, just a few years after Barbaro‘s broken leg in the Preakness, has a lot of people worried about the safety and welfare of thoroughbreds. Statistics on the frequency of horses breaking down are elusive. The closest thing to official statistics I could find comes from an Andrew Beyer column, in . . .
When it comes to creativity and storytelling, my sister Linda Jines got all the talent. She, for instance, is the genius who thought up the title “Freakonomics.” In what we hope will be the first in a long line of guest blog posts, today she toasts my father on his 73rd birthday. Levitt’s father in his balaclava. Edina, Minnesota January . . .
I love Chrysler’s new incentive program that guarantees consumers who buy one of their new cars or trucks won’t pay more than $2.99 a gallon at the pump for the first three years they own the vehicle. When you sign up, you get a special credit card that can only be used to buy gas. When you swipe it, $2.99 . . .
The Chinese think they can keep it from raining on the National Stadium during the Olympics. The Chinese Weather Modification Office employs nearly 53,000 people — it would have been simpler to just build the stadium with a roof. But mandating that the Chinese people cease and desist may prove an easier task for the Chinese government than telling Mother . . .
Robert Jensen Over the last two days, Robert Jensen has described his hunt for the ever-elusive Giffen good. Like all action adventure stories, this one has a happy ending. Jensen then goes on to explain the important implications of his findings for food policy in the developing world. Raiders of the Lost Arc Elasticity, Part III By Robert Jensen What . . .
Robert Jensen In the second installment of his adventure story about searching for the elusive Giffen good, Robert Jensen describes some of the setbacks they suffered along the way. Raiders of the Lost Arc Elasticity, Part II By Robert Jensen Let me start at the beginning to explain how our search for a Giffen good evolved. About five years ago, . . .
A few years back the Wall Street Journal dubbed me the Indiana Jones of economics. Robert Jensen In reality, that title more rightfully belongs to Robert Jensen, an economist at Brown University who is doing some of the most interesting and adventurous economics studies these days. Jensen has documented how cell phones revolutionized fish markets in India, how simply telling . . .
With a field of twenty horses, it is no simple task to pick a winner. Much like last year, there is not a single horse in the field who looks like a positive-expected-value bet according to my (sadly inexact) computer program. Still, the computer says that three horses look like reasonable horses to play in exactas: the likely favorite Big . . .
Last month I blogged about Chris Goodall‘s claim that walking could exacerbate global warming more than driving if the person doing the walking gets his or her calories from foods like beef or milk. A group called the Pacific Institute has done some further analysis of the data. Their analysis suggests that for most reasonable assumptions about the diet of . . .
A modern variant of David versus Goliath is unfolding in academic economics. Ashwini Agrawal is David. He is a graduate student getting a Ph.D. at the University of Chicago Graduate School of Business. The A.F.L.-C.I.O. is Goliath. Here is the background, as I understand it: The A.F.L.-C.I.O. manages huge pension funds for its members. These pension funds are invested in . . .
A few weeks back, just as I finished up my stint as a journal editor, I asked a former University of Chicago economics professor to serve as an anonymous referee on a paper. Usually I wouldn’t ask someone in his eighties to be a referee, but the last time I used this fellow (when he was just a young turk . . .
I was sitting in the student union at the University of Chicago last week when a student came by putting “Free Mumia” leaflets on the tables. I have never paid much attention to the Mumia Abu-Jamal case. On the one hand, I know enough about police, the criminal justice system, and racism to believe that an innocent black man could . . .
No matter what the engineers do, the squirrels still manage to gnaw their way through the garbage bins in my alley. The city keeps coming up with new garbage bins that thwart the squirrels’ previous strategy, but the squirrels just keep coming up with new and better ideas. They used to chew through the lid. So the engineers made the . . .
I blogged a few days back about how letters without postage still get delivered and urged blog readers to carry out some field experiments on the subject. It turns out that blog reader Aaron — who wants his last name withheld (you know how ruthless the Canadian Postal Service can be) — had run a somewhat different experiment in the . . .
My college friend Greg Spira writes in Slate about the exaggerated share of American-born Major League Baseball players with fall birthdays. This is more evidence in support of the idea that arbitrary eligibility cutoffs for youth sports programs have long-term impacts on who invests in the sport and eventually reaches the highest levels. One of our earlier Freakonomics columns in . . .
