Why Aren’t There More Old Criminals?

The Freakonomics in-box regularly fills up with interesting tales (like this one and this one). The other day, a reader from Dallas named Erik Hille took reader e-mail to a whole new level. He was writing about the Feb. 1 entry in our fact-a-day calendar, which excerpts a fact from our book in the chapter on crime: “The average sixty-five-year-old . . .

What’s So Special About the Subprime Mess?

The answer, according to the economists Carmen Reinhart and Kenneth Rogoff, is … “not much.” Here’s what they describe in a new NBER working paper about the causes and consequences of the current subprime crisis: Our examination of the longer historical record finds stunning qualitative and quantitative parallels to 18 earlier post-war banking crises in industrialized countries. Specifically, the run-up . . .



Oversubscribed Classes

I make a brief cameo appearance in this Chronicle of Higher Education article about how universities allocate students to popular courses. It mentions the student who tried to sell her spot in my class, thereby bringing down the wrath of the University administration. I liked her approach, though, so we’ve now got her employed doing research assistance for the sequel . . .



The Macroeconomics of Love: A Valentine’s Day Analysis

Who says there’s no romance in macroeconomics? Betsey Stevenson and I are currently working on a paper for a forthcoming Brookings Panel, assessing the relationship between levels of economic development and various measures of subjective well-being. We are working with an absolutely fabulous data set: the Gallup World Poll. The good folks at Gallup are now surveying people in more . . .

Global Warming and the Minefield of Unintended Consequences

Dubner and Levitt recently wrote a column discussing the unintended consequences of legislation intended to help the neediest segments of society. Few movements for change have met with as many unintended consequences as the efforts, both in the public and private sector, to combat global warming. Take biofuels (another topic Dubner has addressed here and here). Hailed as the darling . . .



Bring Your Questions for Google Economist Hal Varian

I was already a big fan of Hal Varian‘s columns on everyday economics in the Times when I had the good fortune to meet him at Google headquarters, when Levitt and I were out there a couple of years ago. He was even more impressive in person. Now you have a chance to ask him whatever you’d like. As Google’s . . .



Score a Point for Seth Roberts and the Shangri-La Diet

Earlier this week, we linked to a news article about a medical study finding that rats gained about the same amount of weight (80 grams, versus 72 grams on average) when they ate saccharine sweetened yogurt as when they ate yogurt sweetened with glucose. In both cases, the rats ate the yogurt in addition to their regular food. If I . . .

If you’ve followed this blog for a while, you know that some of the best posts are written by readers, not by us.

My 12-year-old son saw it lying around last spring and asked what it was . . .



Does Campaign Spending Matter? Ask Mitt Romney

In Freakonomics, we argued that campaign spending matters a lot less than people think. Mitt Romney‘s presidential campaign would seem to offer a fresh bit of evidence in favor of our theory. Viewed in this light, Hillary Clinton‘s decision to loan her campaign $5 million looks like the wrong move. It isn’t the money that is boosting Obama. Rather, it’s . . .

Analyzing Roger Clemens: A Step-by-Step Guide

Yesterday, I posted about the conclusions that Eric Bradlow, Shane Jensen, Adi Wyner, and I drew from analyzing Roger Clemens‘s career statistics. I thought that it might be useful to show how we got from the findings in the Clemens Report (exonerating him), to our somewhat opposite conclusions. So for budding forensic economists, here is a step-by-step guide, with pictures. . . .



The Simple Tax Return

Economist Austan Goolsbee has a $44 billion idea called the “Simple Return”: Around two-thirds of taxpayers take only the standard deduction and do not itemize. Frequently, all of their income is solely from wages from one employer and interest income from one bank. For almost all of these people, the IRS already receives information about each of their sources of . . .

Sports fans will probably be aware that Roger Clemens is currently before Congress, arguing that the Mitchell Report wrongly tagged him as having used performance-enhancing drugs. And last week, his agents released the “Clemens Report,” arguing that his career statistics somehow exonerate him. The full marketing spin is available here.

Offshoring Lung Cancer?

The Wall Street Journal reports on a new World Health Organization study about cigarette smoking around the world. The Journal‘s piece includes data from Euromonitor International about the number of cigarettes sold worldwide by various manufacturers.

The Economics of Obesity: A Q&A With the Author of The Fattening of America

We’ve blogged about obesity at length here at Freakonomics. The health economist Eric Finkelstein has been studying the subject for years, and, along with co-author Laurie Zuckerman, has just published a book, The Fattening of America, which analyzes the causes and consequences of obesity in the U.S. Finkelstein agreed to answer our questions about the book. Q: You state that . . .



Acceptable Biases, and Unacceptable Ones

We’ve written in the past about the very thin line that separates an acceptable expression of racial or ethnic bias from an unacceptable one — for instance, the tumult over Andy Rooney writing that “today’s baseball stars are all guys named Rodriguez to me.” As we wrote in Freakonomics, evidence from the TV show Weakest Link suggested that bias against . . .

Who’s Against Transparency in Government? A Guest Post

Peter Hain has resigned as the U.K.’s Secretary of State for Work and Pensions because he failed to declare “donations to his campaign for the Labour deputy leadership worth more than ?100,000.” But Bruce Ackerman and I think that the campaign disclosure law is misguided, and suggest an alternative in an op-ed that we wrote in The Guardian.

Is New York Still the Financial Capital of the World?

These days, many Americans — including Mike Bloomberg and Chuck Schumer — fear the answer to that question will soon be “no,” if it isn’t already; London is poised to take over.

Are Men Really More Competitive Than Women?

The conventional wisdom holds that men and women have different abilities when it comes to competition (a view that’s certainly being challenged in the current Democratic primary). Labels like “lacking the killer instinct,” “peacemaker,” and “avoiding confrontation” are commonly assigned to women in competitive environments, while the supposed male knack for thriving in competition is cited as a reason for . . .



We Had Better Get Our Next Book Out: John DiNardo Is Getting Bored

As mentioned on MarginalRevolution, the economist John DiNardo has been quite busy over the last few years criticizing Freakonomics. He has written no fewer than three papers on the subject. It’s too bad that he didn’t offer the standard academic courtesy of sending his criticisms directly to me before writing them up; if he had, I could have helped clarify . . .

That is the promise being made by a company called QLess, which offers “virtual queue management” via cellphone* alerts.
