Is Our Content Too Depressing?

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.

The Dangers of Being a Creature of Habit

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).

What Kind of Beer Is Most Likely to Land You in the E.R.?

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.

Why Don't More Professional Drivers Use Traffic-Enabled GPS?

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?

Those Brutal Ballplayers

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.

*He is also married to my niece.

Losing Experienced Teachers Is Bad for Schools, Right?

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.

Judge to Mom: "Thou Shalt Not Name Thy Child 'Messiah'"

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.

Different Kinds of Moms Have Babies at Different Times of Year

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.

How Much Tax Are Athletes Willing to Pay?

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.

Selling Off the Family Business

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 Candidates for AEA Elections Tell Us What They're Thinking?

Joshua Gans is an economist at the University of Toronto. He has appeared on this blog before and, as the author of Parentonomics: An Economist Dad Looks at Parenting, was featured in our podcast “The Economist’s Guide to Parenting.” He has a long-standing interest in the economics of science as well as studies of the economics profession. He is also a long-standing member of the American Economic Association. On that last note, he has written a thoughtful essay that wonders if the candidates standing for AEA elections should be required, or at least encouraged, to be more forthcoming about what they’d stand for if elected.

 

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?

The Burger Debate Catches a Second Wind

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.

File Under "Not All Additives Are Bad for You"

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?

No Online Sex Please, We're British

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.

Would a Computer-Driven Vehicle Make This Kind of Error?

Reading about the horrific train crash in Spain that killed at least 80, and thinking back to the (rare) fatal airplane crash in San Francisco brought to mind the ride I took in a driverless car a few months back at Carnegie Mellon University. Many people still distrust a computer to get them from Point A to B. How long will it be before our thinking changes and we distrust humans to do the same? The train and plane crashes both appear to be due to human error, as are the vast majority of automobile crashes (which kill more than 1 million people worldwide each year).

I haven’t spent all that much time in Spain but one of the most striking observations from a recent visit was how hard it is to buy a train ticket from a machine. In many cases, you have to wait in (long) line for a human ticket-seller. Whenever I asked why, I was told this was simply done to protect jobs — an understandable, if unsatisfying, defense in a country with 27% unemployment.

It does make me wonder how much a country or culture with a strong sense of job protection will be resistant to technological changes purely on employment grounds, even if they might produce large gains for the greater good.

Anthony Weiner's Sunk Costs?

Anthony Weiner is still running for mayor of New York as I write this, though that status may soon change. Not coincidentally, a reader named Jon Creem (an unfortunate aptonym in this case?) writes in to say:

Yesterday I enjoyed listening to your show about “Quitting.” The segment where you explained “sunk cost” was especially interesting.

I took the explanation as people’s unwillingness to give up due to the amount of investment (time, money, etc) they have already made.

Then, when catching up on the latest Anthony Weiner mayoral saga, I couldn’t help make a connection.

Is this guy refusing to remove himself from the race because he feels he has done too much already to drop out now? In my opinion the odds are stacked against him regardless of how good a politician he is.

I assume continuing to campaign will only cost him more time and money. Is it worth it for him to continue?

Insofar as pride and ego are components of sunk cost, I guess Jon is right. On the other hand, it doesn’t strike me that Weiner’s continuing to run is really about sunk cost. Modern politics is so often an exercise in ego, hubris, and narcissism — and if I were to armchair-analyze Weiner, I’d suggest that these factors are much more important than the sunk costs of time and money.

Why GDP Will Rise (Not What You Think)

In Bloomberg BusinessWeek, Peter Coy writes an excellent piece on the Bureau of Economic Analysis’s upcoming revision of  Gross Domestic Product measurement. That may not sound very interesting but Coy does a great job showing the macro and micro angles. To wit:

On July 31, the U.S. Bureau of Economic Analysis will rewrite history on a grand scale by restating the size and composition of the gross domestic product, all the way back to the first year it was recorded, 1929. The biggest change will be the reclassification—nay, the elevation—of research and development. R&D will no longer be treated as a mere expense, like the electricity bill or food for the company cafeteria. It will be categorized on the government’s books as an investment, akin to constructing a factory or digging a mine. In another victory for intellectual property, original works of art such as films, music, and books will be treated for the first time as long-lived assets.

And:

The U.S. generates a disproportionate share of its wealth from the likes of patents, copyrights, trademarks, designs, cultural creations, and business processes. To see the intangible economy in numbers, look at Apple’s (AAPL) balance sheet: Property, plant, and equipment, those traditional forms of wealth from the industrial and preindustrial eras, account for $15 billion of its $400 billion market value—just 4 percent of the total. They’re only 7 percent of market value at moviemaker Time Warner (TWX) and drugmaker Pfizer (PFE).

College Makes You Healthy

At the core of the debate over the value of college is a collage of evidence showing that it produces better lifetime outcomes not just in income but in health and happiness. How does this happen? And how can we be sure that we aren’t just seeing a selection bias — i.e., that people who go to college would have been richer, healthier, and happier in any case?

Here’s a new working paper (abstract; PDF), by Kasey Buckles, Andreas Hagemann, Ofer Malamud, Melinda Morrill, and Abigail Wozniak which purports to show the long-term health effects of a college education. Granted, their data stretches back to the Vietnam War draft (a good instrumental variable, which other researchers have used) but their findings are significant nonetheless.

We exploit exogenous variation in college completion induced by draft-avoidance behavior during the Vietnam War to examine the impact of college completion on adult mortality.  Our preferred estimates imply that increasing college completion rates from the level of the state with the lowest induced rate to the highest would decrease
cumulative mortality by 28 percent relative to the mean.  Most of the reduction in mortality is from deaths due to cancer and heart disease.  We also explore potential mechanisms, including differential earnings, health insurance, and health behaviors, using data from the Census, ACS, and NHIS.

Differential earnings and health insurance are of course related to the income boost that college graduates receive. It is the “health behaviors” that are learned/adopted by college graduates that are especially interesting.

The Wintry Economics of the Arab Spring

Most of the coverage of the turmoil in Egypt and Syria (the latter of which has decreased in proportion to an increase in coverage of the former) focuses on political, religious, and social factors. These are all obviously important. But once you read David P. Goldman‘s op-ed in the Wall Street Journal about the economic underpinnings of the Arab revolutions, you may see things differently. A few key excerpts:

Sometimes economies can’t be fixed after decades of statist misdirection, and the people simply get up and go. Since the debt crisis of the 1980s, 10 million poor Mexicans—victims of a post-revolutionary policy that kept rural Mexicans trapped on government-owned collective farms—have migrated to the United States. Today, Egyptians and Syrians face economic problems much worse than Mexico’s, but there is nowhere for them to go. Half a century of socialist mismanagement has left the two Arab states unable to meet the basic needs of their people, with economies so damaged that they may be past the point of recovery in our lifetimes.

This is the crucial background to understanding the state failure in Egypt and civil war in Syria. It may not be within America’s power to reverse their free falls; the best scenario for the U.S. is to manage the chaos as best it can.

Has the U.S. Reached "Peak Motorization"?

Peak oil? Probably not. But have we reached “peak motorization” in the U.S.?

Michael Sivak of the University of Michigan’s Transportation Research Institute says the answer is quite possibly yes:

The absolute number of vehicles reached a maximum in 2008. However, it is likely that this was only a temporary maximum and that the decline after 2008 was primarily driven by the current economic downturn that started in 2008. Consequently, with the improving economy and the expected increase in the U.S. population, it is highly likely that (from a long-term perspective) the absolute number of vehicles has not yet peaked.On the other hand, the rates of vehicles per person, licensed driver, and household reached their maxima prior to the onset of the current economic downturn. Consequently, it is likely that the declines in these rates prior to the current economic downturn (i.e., prior to 2008) reflect other societal changes that influence the need for vehicles (e.g., increases in telecommuting and in the use of public transportation). Therefore, the recent maxima in these rates have better chances of being long-term peaks as well.

But Sivak is smart enough to hedge his prediction:

However, because the changes in the rates from 2008 on likely reflect both the relevant societal changes and the current economic downturn, whether the recent maxima in the rates will represent long-term peaks as well will be influenced by the extent to which the relevant societal changes turn out to be permanent.

In the Season of Aaron Hernandez, Try Some Jacky Kaba and Shamarko Thomas

I like following sports for a lot of reasons beyond the sheer entertainment; I’ve explained why here
and here. The cast of characters is constantly evolving and, often, capable of producing true drama. Sometimes this drama takes the form of an Aaron Hernandez crime story. But more often, if you’re willing to look, you’ll find the story of a Jacky Kaba or a Shamarko Thomas.

Who???

Here, read for yourselves. Jacky Kaba, originally from Liberia, played basketball at Seton Hall University and is now an associate professor of sociology there; his research has appeared on our blog. Jerry Izenberg has written a fine piece about Kaba on the occasion of his gaining U.S. citizenship.

Shamarko Thomas is an undersized defensive back just drafted by the Pittsburgh Steelers; Everett Cook has written an inspiring article about his personal and familial struggles to date. I hope Thomas prospers (and I say that not just because he’s a Steeler).
