We recently published a post about what seemed like an aptonym — a researcher named Thomas Collins who’s been studying the chemical footprints of whiskeys. Does he in fact share a name with the cocktail Tom Collins, or does he stick to Thomas? Thankfully, Professor Collins (or someone doing a good impression of him) left a comment on the post:
I do go by Tom. I, too, heard every combination of comments about what my parents might have been drinking, etc. I made a deliberate choice, therefore, to study whiskeys rather than gin …
Cheers!
A 19th-century Georgia land lottery may have something to teach us about today’s income inequality.
Think you know how much parents matter? Think again. Economists crunch the numbers to learn the ROI on child-rearing.
Marc Resnick, a professor of human factors and information design at Bentley University, writes to say:
I came across this fantastic aptonym today and as a major Freakonomics fan I had to share it with you: A research team at U.C.-Davis just published a study on the chemical fingerprints of American whiskeys. And the lead researcher is Tom Collins.
To be fair, the scholar’s name is Thomas Collins (he is director of the university’s Food Safety and Measurement Facility), and we don’t know if he really goes by Tom.* Furthermore, Tom Collins the drink is made with gin, which isn’t a whiskey, the beverage under study here. But still … fantastic. Thanks, Marc.
*Prof. Collins, please drop us a line and let us know if you do.
In our “Legacy of a Jerk” podcast, we discussed (among other things) the injunction against speaking ill of the dead. It featured an interview with a daughter of a woman named Carole Roberson, whose obituary stated that she was “a difficult mother and a horrendous mother-in-law.” That said, the obituary also said that “she will STILL be missed.”
Several readers have now sent us this A.P. article about an obituary for a Nevada woman named Marianne Theresa Johnson-Reddick. She makes Carole Roberson sounds like an angel.
“On behalf of her children who she abrasively exposed to her evil and violent life, we celebrate her passing from this earth and hope she lives in the after-life reliving each gesture of violence, cruelty and shame that she delivered on her children,” the scathing obituary begins. … [It] was written by Johnson-Reddick’s adult children, whose horror stories prompted Nevada to become one of the first states to allow children to sever parental ties back in the 1980s. …
Once upon a time, office workers across America lived in fear of a dreaded infirmity. Was the computer keyboard really the villain — and did carpal tunnel syndrome really go away?
From a reader named Eric Geyer:
I was listening to one of your first podcasts, “The Dangers of Safety.” In the podcast, you say “There hasn’t been a single on-field death in the NFL.”
This isn’t completely true — there has been one, I remember it from when I was a kid. A player for the Detroit Lions named Chuck Hughes collapsed and died in the field in 1971. This doesn’t invalidate your point from the story — his death was not related to a football injury, but was caused by a heart attack.
Anyway, in case no other overzealous pedant hadn’t pointed this out, I thought you would like to know 🙂
Thanks, Eric.
The argument over tenure for university professors is a long and boisterous one.
Levitt, for one, is in favor of abolition. If you are on that side of the argument as well, you may be pleased to read a new working paper by David Figlio, Morton Schapiro, and Kevin Soter (all associated with Northwestern, in one capacity or another) called “Are Tenure Track Professors Better Teachers?” (gated, sorry). Short answer (in their study, at least): no.
The abstract:
This study makes use of detailed student-level data from eight cohorts of first-year students at Northwestern University to investigate the relative effects of tenure track/tenured versus non-tenure line faculty on student learning. We focus on classes taken during a student’s first term at Northwestern, and employ a unique identification strategy in which we control for both student-level fixed effects and next-class-taken fixed effects to measure the degree to which non-tenure line faculty contribute more or less to lasting student learning than do other faculty. We find consistent evidence that students learn relatively more from non-tenure line professors in their introductory courses. These differences are present across a wide variety of subject areas, and are particularly pronounced for Northwestern’s average students and less-qualified students.
There are more than twice as many suicides as murders in the U.S., but suicide attracts far less scrutiny. Freakonomics Radio digs through the numbers and finds all kinds of surprises.
These aren’t my words. Listen to John R. Beard, who runs the Department of Ageing and Life Course for the World Health Organization:
“To some extent, we treat women as vessels of reproduction, and once they’ve done that we don’t pay much attention to them.”
That’s from Don McNeil‘s Times article about women’s life expectancy:
Life expectancy for women who live to age 50 is going up around the world, but poor and middle-income countries could easily make greater gains, according to a new World Health Organization report.
Heart disease, stroke and cancer kill most women over 50, said Dr. John R. Beard, director of the W.H.O.’s department of aging, so countries should focus on lowering blood pressure with inexpensive drugs and screening for cervical and breast cancer. Those diseases can be prevented or treated, said Dr. Beard, who was also an author of the study, which was published in the Bulletin of the World Health Organization.
Related (if barely): Ronald Coase has died at age 102.
“The African region has 2 percent of the world’s registered vehicles but a disproportionate 16 percent of the world’s road traffic deaths,” said Tami Toroyan, a technical officer in the department of violence and injury prevention at the World Health Organization in Geneva.
We’ve talked in the past about the massive potential upsides of self-driving vehicles. Just this week came word that Nissan hopes to bring autonomous vehicles to the market by 2020. If you read this heartbreaking Times article by Nicholas Kulish about a series of bus crashes in Kenya (from which the quote above is taken), you may be ready for such vehicles even sooner.
There are of course many barriers to get past before the world is ready for autonomous vehicles — yes, there will be lawsuits of all kinds and yes, professional drivers all over will protest the loss of jobs and yes, there will be people who trust a human driver more than a computer driver — but I do wouldn’t be shocked if my grandchildren grow up in a world where “driving a car” seems like something that cavemen used to do.
It’s impossible to say for sure, but the Lebanese do remarkably well. Why?
A Freakonomics Radio listener named Sudha Krishna writes with an e-mail titled “Praise and Concern.”
The praise is very nice — she finds the show “informative, entertaining, and lots of fun,” etc. — but it is the concern that most interests me. As she writes:
I confess I often find Freakonomics Radio depressing. While I am a believer in the power of “unintended consequences,” I find your story selection (and I am a consistent and attentive listener) depressing and discouraging. The stories tend to be focused on (and I am being a wee bit reductive) “good intentions leading to bad consequences (or at very least awry).” The consistent lesson of every episode — a nod to the supremacy of the market and the inexorable power of incentives (not sure about that lesson either). Rarely do you explore the opposite — bad intentions resulting in good consequences. Does such an example exist? One curious listener of Freakonomics Radio wants to know.
I could probably quarrel a little bit with Sudha — at least some of our shows are about some interesting solution to a problem, or at least an explanation for why such a problem exists. And I tend to think that Levitt and I are borderline extreme optimists, at least on many dimensions. But I get her point. The pattern she identifies is definitely a pattern.
So, in the interest of learning to think more broadly, I would love to identify some great ideas or stories about “bad intentions resulting in good consequences,” as Sudha puts it. Please leave your very best ideas (or even your mediocre ones) in the comments section below. Thanks to you and especially to Sudha.
Blane Nordahl is very good at stealing high-end silver from old homes all over the U.S. He is also, however, a creature of habit. His methodology is so constant, and so distinct, that if a bunch of silver starts to disappear, it becomes obvious to those who know his m.o. that Nordahl is responsible. Then he is hunted down, arrested, and sent to prison for a while — after which he is released and goes right back to his stealing ways.
Back in 2004, I wrote a long article about Nordahl for The New Yorker. There were two detectives who knew just about everything about Nordahl: Cornell Abruzzini, then of the Greenwich, Conn., police force; and Lonnie Mason, a retired New Jersey detective. Abruzzini is still a cop in Connecticut; Mason is still retired. But that didn’t stop Mason from contributing to the last manhunt for Nordahl, helping police departments across the south gather evidence against him. This resulted in the re-arrest of Nordahl early yesterday. The New York Times has the whole story on its front page today, written by Kim Severson.
If you are a TV or movie producer thinking about hijacking this story, you should note that Law and Order already did it (“ripped from the headlines” indeed).
Human beings love to predict the future, but we’re quite terrible at it. So how about punishing all those bad predictions?
A new study (gated) published in Substance Abuse & Misuse and summarized by Anahad O’Connor in The New York Times identifies the brands of beer most often drunk by people who end up in a hospital emergency room:
The study, carried out over the course of a year at the Johns Hopkins Hospital in Baltimore, found that five beer brands were consumed most often by people who ended up in the emergency room. They were Budweiser, Steel Reserve, Colt 45, Bud Ice and Bud Light.
Three of the brands are malt liquors, which typically contain more alcohol than regular beer. Four malt liquors accounted for nearly half of the beer consumption by emergency room patients, even though they account for less than 3 percent of beer consumption in the general population.
A couple years ago, when I first noticed the ability to overlay a traffic report on Google Maps on my iPhone, I assumed that the world of drivers — especially people who drive for a living — would take it up very quickly. In a place like New York, choosing a free-flowing route versus a congested route might save you 30 or even 60 minutes on an airport trip.
But I seem to have been quite wrong. In most instances when I take a taxi or hired car to/from an airport, the driver doesn’t check any kind of device to see where traffic is heavy and where it’s light, even though smartphones with map and traffic apps have exploded in the last couple of years. Once in a while, he’ll tune in to the all-news radio station to get a spotty traffic update.
Therefore, I usually now check my traffic app as soon as I get in the car to see what routes are looking good and which are looking bad, and then relay that info to the driver. Why don’t more professional drivers use traffic-enabled GPS?
Too much cheating, substance abuse, and violence among baseball players? Absolutely — 100 years ago. A great read from Tobias Seamon* in The Morning News:
Ty Cobb had a nervous breakdown in his rookie season; Pittsburgh’s Ed Doheny was committed to an asylum in 1903, with a local paper declaring “His Mind Is Thought To Be Deranged”; in 1907, Chick Stahl borrowed from the fiendish Bowery dive McGurk’s Suicide Hall and ingested carbolic acid; Patsy Tebeau, player-manager for the hard-drinking Cleveland Spiders in the 1890s, later shot himself; in 1900 Boston’s Marty Bergen slit his throat after killing his wife and two children with an axe; Hall of Famer Old Hoss Radbourn, who had half of his face blown off in a hunting accident, became demented from syphilis; the notorious drunk Bugs Raymond of the New York Giants once illustrated his curve by hurling a mug through a restaurant’s plate-glass window; Mike “King” Kelly drank himself into an early grave but not before creating the devil-may-care jock stereotype in America.

Chicago has given the world more than sausage, crooked politics, and Da Bears.
Maybe not. A new working paper (abstract; PDF) by Maria Fitzpatrick and Michael Lovenheim finds that offering early retirement to experienced schoolteachers doesn’t have a negative effect on students’ test scores, and in some cases leads to an improvement. The abstract:
Early retirement incentives (ERIs) are increasingly prevalent in education as districts seek to close budget gaps by replacing expensive experienced teachers with lower-cost newer teachers. Combined with the aging of the teacher workforce, these ERIs are likely to change the composition of teachers dramatically in the coming years. We use exogenous variation from an ERI program in Illinois in the mid-1990s to provide the first evidence in the literature of the effects of large-scale teacher retirements on student achievement. We find the program did not reduce test scores; likely, it increased them, with positive effects most pronounced in lower-SES schools.
Just another false messiah, it seems. From the Associated Press:
A judge in Tennessee changed a 7-month-old boy’s name to Martin from Messiah, saying the religious name was earned by one person and “that one person is Jesus Christ.” …
“It could put him at odds with a lot of people and at this point he has had no choice in what his name is,” [Magristrate Lu Ann] Ballew said.
It was the first time she ordered a first name change, the judge said.
Messiah was No. 4 among the fastest-rising baby names in 2012, according to the Social Security Administration’s annual list of popular baby names. …
The boy’s mother, Jaleesa Martin, of Newport, said she will appeal. She says Messiah is unique and she liked how it sounded alongside the boy’s two siblings — Micah and Mason.
I am eager to read your comments on this one.
We’ve written in the past about the relationship between a child’s month of birth and a variety of later outcomes. In SuperFreakonomics, for instance, we wrote about research by Douglas Almond and Bhashkar Mazumder showing that “prenatal exposure to Ramadan results in lower birth weight.” In a Times column called “A Star Is Made,” we examined the link between birth month and accomplishment in sports. We also noted, however, in SuperFreak, that the sports advantage — and probably many other birth-month influences — are relatively small:
But as prevalent as birth effects are, it would be wrong to overemphasize their pull. Birth timing may push a marginal child over the edge, but other forces are far, far more powerful. If you want your child to play Major League Baseball, the most important thing you can do — infinitely more important than timing an August delivery date — is make sure the baby isn’t born with two X chromosomes. Now that you’ve got a son instead of a daughter, you should know about a single factor that makes him eight hundred times more likely to play in the majors than a random boy.
What could possibly have such a mighty influence?
Having a father who also played Major League Baseball. So if your son doesn’t make the majors, you have no one to blame but yourself: you should have practiced harder when you were a kid.
That said, there is a rather large body of literature on the topic of birth month and its relationship to later outcomes. Which is why it’s interesting to see a paper (working version here), just published in The Review of Economics and Statistics, which offers a different angle on all this birth-month conversation.
We worship the tradition of handing off a family business to the next generation. But is that really such a good idea?
The Laffer Curve is a unicorn-y concept that seeks to explain the rate of taxation at which revenues will fall because earners either move away or decide to earn less (or cheat more, I guess).
If I were a tax scholar interested in this concept, I would be taking a good, hard look at the current behavior of top-tier professional athletes. Boxing is particularly interesting because it allows a participant to choose where he performs. If you are a pro golfer or tennis player, you might be inclined to skip a particular event because of a tax situation, but you generally need to play where the event is happening. A top-ranked boxer, meanwhile, can fight where he gets the best deal.
Which is why it’s interesting to read that Manny Pacquiao will probably never fight in New York — primarily, says promoter Bob Arum, because of the taxes he’d have to pay.
With the recent sale of The Washington Post to Jeff Bezos, the less-recent sale of the Wall Street Journal to Rupert Murdoch’s News Corp., and the N.Y. Times’s exuberant denial that it is for sale, one thing came to mind: family businesses.
Not an obvious common thread, perhaps. But I have long been interested in how family-run businesses succeed or fail — and in fact this week have just re-released an hour-long Freakonomics Radio podcast on the topic, “The Church of ‘Scionology’” (subscribe here). It features stories on a pair of family beer businesses — Anheuser-Busch and Yuengling — as well as the strange tale of adult adoptions in Japan in the service of corporate stability (i.e., if your son or daughter isn’t up for the job of running your company, then you can simply adopt your successor).
The Post and Journal were long-held family businesses, the Post by the Graham family and the Journal by the Bancrofts. The Times, in an ownership structure similar to the Post, is a public company whose voting shares are controlled by the Ochs-Sulzberger family, and Arthur Sulzberger, like his ancestors before him, is the publisher of the newspaper. I haven’t worked at the Times for some time but the feeling then — and I am told that the feeling persists — is that the Sulzberger family has done an extraordinary job of protecting the editorial integrity of the newspaper, as might be expected of a family steward, but has been less competent than one might wish in shepherding its business interests. (This is all speculation, of course, as there is no counterfactual.)

Should We Learn More About AEA Candidates?
By Joshua Gans
It is that time of year when the 18,000 members of the American Economic Association (AEA) receive their ballots to vote for the society’s leadership. I have been voting in AEA elections for 25 years and the information provided is always the same. There is a voting sheet and then a pamphlet listing the bios of each candidate (e.g., significant publications, awards and administrative positions held) and a photo of each (see here). This is not a lot of information to go on. In my younger days, when I had little personal information on the candidates I would choose on their basis of their work, whether they are close to my field of interest (macro vs. micro, theory vs. empirical), and perhaps whether their politics matched my own.
These days I know many of the candidates both professionally and personally, and so now I factor into the equation whether I think they will be good leaders of the AEA. This may be correlated with the information in their bios but it is not a given. Very often I have found those who are less widely known in the public to have thoughtful ideas about the AEA and economics profession. That gives rise to a natural question: should we know more about AEA candidates than is presented to us formally?
Even American parents have a strong “son preference” — which means that a newborn daughter can be bad news for a marriage.
Remember this blog post in which a reader asked if the McDouble is perhaps “the cheapest, most nutritious, and bountiful food that has ever existed in human history”? It spawned a lot of commentary on the blog and we followed it up with a Freakonomics Radio podcast.
Now the question has been taken up by many others, spurred on by a N.Y. Post column by Kyle Smith and echoed by, among others, Yahoo! and the Wall Street Journal in this country and, in the U.K., the Telegraph, the Daily Mail, and the Times.
I have gotten about one zillion media requests to talk further about the story but I am busy writing so I had to turn them down.
If you scroll through the comments on the links above — the Yahoo! post has more than 4,000 comments as of this writing — you will likely be struck, as I was, by how great Freakonomics commenters are compared to the rest of the world. Literate, lucid, knowledgable, and even when you get enraged you manage to say something useful.
All hail the readers of this blog!
We have all been pretty conditioned these last several years to view food additives of any sort as pure negatives. So it’s interesting to look back to an earlier time and see the effect of an additive that practically no one can argue with. James Feyrer, Dimitra Politi, and David Weil have written a new working paper (abstract; PDF from 2008) about the effect of adding iodine to table salt:
Iodine deficiency is the leading cause of preventable mental retardation in the world today. The condition, which was common in the developed world until the introduction of iodized salt in the 1920s, is connected to low iodine levels in the soil and water. We examine the impact of salt iodization on cognitive outcomes in the U.S. by taking advantage of this natural geographic variation. Salt was iodized over a very short period of time beginning in 1924. We use military data collected during WWI and WWII to compare outcomes of cohorts born before and after iodization, in localities that were naturally poor and rich in iodine. We find that for the one-quarter of the population most deficient in iodine this intervention raised IQ by approximately one standard deviation. Our results can explain roughly one decade’s worth of the upward trend in IQ in the U.S. (the Flynn Effect). We also document a large increase in thyroid related deaths following the countrywide adoption of iodized salt, which affected mostly older individuals in localities with high prevalence of iodine deficiency.
Iodine is hardly the only beneficial additive in our food supply. There’s vitamins A and D in milk. And fluoride in the water? None of these are completely without controversy of course. What other mostly beneficial additives can you think of?
According to a BBC News report:
Most households in the U.K. will have pornography blocked by their internet provider unless they choose to receive it, David Cameron has announced. …
Mr Cameron warned in a speech that access to online pornography was “corroding childhood.”
The new measures will apply to both existing and new customers.
Mr Cameron also called for some “horrific” internet search terms to be “blacklisted,” meaning they would automatically bring up no results on websites such as Google or Bing.
You could spend a week reading the comments, which are quite heterogeneous.
