A Quick Summary of the 21st Century So Far

From a reader named Kevin Murphy (alas, not the Kevin Murphy):

The Economist just reported on what you covered in the “The Downside of More Miles Per Gallon” podcast in February. It’s looking like Oregon is leading the way in possibly charging per mile: “A bill that would have applied a VMT fee to all new vehicles doing 55mpg and above died in the last legislative session; instead, 5,000 volunteers will join a new VMT scheme in July 2015. They will be charged at 1.5 cents per mile rather than paying the state petrol tax (30 cents per gallon).”

Should Marriage Be More Like an Employment Contract?

A reader named J.D. Peralta is asking for your help:

For about the last six years I have developing a theory about how marriage should be legal social contracts.  I feel that legal marriage (not marriage by the church) should be treated more like employment agreements. These “marriage contracts” should bring with them a term that ranges from 3-5 years. The term of the contracts will be developed by both parties but I feel that they should include things like expectation, key areas of responsibilities, etc.

I have been working on this in my spare time but I am currently taking a management class for my bachelor’s degree and I have the opportunity to really put some muscle behind this theory. That is where I need your help. I have been researching this topic for the last two weeks but I have found very little data that could be considered as legitimate sources to support my argument.  I am hoping that you can point me to some reference that help me to complete my argument.  Any assistance you can provided me would be greatly appreciated.

A bit more about Peralta. He is 32, works as an accountant for a public accounting firm in Los Angeles, was born in El Salvador but has lived in the U.S. since 1986. His parents have been married for 39 years; he has two older brothers. “In case you are curious I do have a girlfriend,” he writes, “and we have been together for almost 5 years. I have discussed my theory with her and she finds the concept reasonable.”

Why Are the Japanese No Longer Interested in Sex?

From the Guardian:

Japan’s under-40s appear to be losing interest in conventional relationships. Millions aren’t even dating, and increasing numbers can’t be bothered with sex. For their government, “celibacy syndrome” is part of a looming national catastrophe. Japan already has one of the world’s lowest birth rates. Its population of 126 million, which has been shrinking for the past decade, is projected to plunge a further one-third by 2060.

And:

The number of single people has reached a record high. A survey in 2011 found that 61% of unmarried men and 49% of women aged 18-34 were not in any kind of romantic relationship, a rise of almost 10% from five years earlier. Another study found that a third of people under 30 had never dated at all. (There are no figures for same-sex relationships.) Although there has long been a pragmatic separation of love and sex in Japan – a country mostly free of religious morals – sex fares no better. A survey earlier this year by the Japan Family Planning Association (JFPA) found that 45% of women aged 16-24 “were not interested in or despised sexual contact.” More than a quarter of men felt the same way.

 The article contains a number of speculations as to cause, well worth reading. At least the Malthusians will be happy.

Should Tipping Be Banned?

Season 4, Episode 5

The practice of tipping is one of the most irrational, un-economic behaviors we engage in. It’s not in our economic best-interest to tip; essentially we do it because it’s a social norm — a nicety. In this episode of Freakonomics Radio, Stephen Dubner looks at why we tip, what kinds of things can nudge tips upward, and what’s wrong with tipping overall. In the end, we wonder whether or not the practice of tipping should be eliminated altogether. Research shows that African American waiters make less in tips than people of other races, so tipping is a discriminatory practice. Later in the hour: if your parent has the gene for Huntington’s disease you have a 50% chance of getting it yourself. Huntington’s is a debilitating fatal disorder. People can do genetic testing to see if they will fall ill, yet only 5% of people choose to do so. Stephen Dubner talks to University of Chicago economist Emily Oster about her research on Huntington’s genetic testing, and the value of not knowing your fate.

The Cobra Effect

Season 4, Episode 4

If you want to get rid of a nasty invasive pest, it might seem sensible to offer a bounty as a reward. But the problem is: nothing backfires quite like a bounty. In this episode of Freakonomics Radio, we look at bounties on snakes in Delhi, India; rats in Hanoi, Vietnam; and feral pigs in Fort Benning, Georgia. In each case, bounty seekers came up with creative ways to maximize their payoff – and pest populations grew. Stephen Dubner and Steve Levitt talk about how incentives don’t always work out the way we expect them to. Later in the hour, if you want to write a book about Winston Churchill, you are going to have to pay. The Churchill estate is intensely protective of Sir Winston’s copyright, so much so that if you write a book about him, you are likely to go into the red. Stephen Dubner talks about who owns words, and what it will cost you to write a book about Churchill.

Spite Happens

Season 4, Episode 3

This episode of Freakonomics Radio explores our surprising propensity for spite. We discover the gruesome etymology of the phrase “cut off your nose to spite your face” (it involves Medieval nuns cutting off their noses to preserve their chastity). Stephen Dubner and economist Benedikt Herrmann talk about so-called “money-burning” lab experiments, in which people often choose to take money away from other participants – even when it means giving up some of their own cash. Also: why do we take pleasure in harming others? So much so that we’re willing to harm ourselves in the process? The answer may lie in our biology: Freakonomics Radio producer Katherine Wells talks with biologist E. O. Wilson about whether spite exists in nature. Later in the hour, we head to Bogota, Colombia, where the mayor used unconventional methods to bring order to the city: he hired mimes to mimic and embarrass people who were violating traffic laws — and it worked. Then, Stephen Dubner talks to Robert Cialdini, best known for his research on the psychology of persuasion, about how peer pressure, and good old fashioned shame, can greatly affect the way people behave.

How Much Does Your Name Matter?

Season 4, Episode 2

When Harvard professor Latanya Sweeney Googled her name one day, she noticed something strange: an ad for a background check website came up in the results, with the heading: “Latanya Sweeney, Arrested?” But she had never been arrested, and neither had the only other Latanya Sweeney in the U.S. So why did the ad suggest so? Thousands of Google searches later, Sweeney discovered that Googling traditionally black names is more likely to produce an ad suggestive of a criminal background. Why? In this episode of Freakonomics Radio, Stephen Dubner investigates the latest research on names. Steve Levitt talks about his groundbreaking research on names, economic status, and race. And University of Chicago economist Eric Oliver explains why a baby named “Cody” is more likely to belong to conservative parents, and why another named “Esme” was probably born to a pair of liberals.

Women Are Not Men

Season 4, Episode 1

Women are different from men, by a lot, in some key areas. For example, data show that women don’t: drown, compete as hard, get struck by lightning, use the Internet, edit Wikipedia, engage in delinquent behavior, or file patents as much as men do – and these are just some of the examples. Another way women are different from men? They have made significant economic gains and yet they are less happy now than they were 30 years ago. So, how do we explain this paradox? In this episode of Freakonomics Radio, Stephen Dubner looks at some of the ways that women are not men. Later in the hour, Dubner talks to Harvard psychologist Steven Pinker about his research on the history of violence. Pinker has a surprising and counterintuitive thesis: violence has declined and the world is a much more peaceful place than it has ever been.

Sure, "Saving Our Grandchildren From Climate Change" Sounds Nice…

You want to know what the biggest obstacle to dealing with climate change is? Simple: time. It will take decades before the carbon dioxide we emit now begins to have its full effect on the planet’s climate. And by the same token, it will take decades before we are able to enjoy the positive climate effects of reducing carbon-dioxide emissions now. (Even if we could stop emitting all CO? today, there’s already future warming that’s been baked into the system, thanks to past emission.)

That is the lead of Bryan Walsh‘s excellent Time article called “Why We Don’t Care About Saving Our Grandchildren From Climate Change.” It covers much of the ground we covered in SuperFreakonomics but probably does a better job in laying out the inherent conflicts of climate change — long-term problem vs. short-term incentives — without enraging people.

The Unsustainable Economics of Cancer Drugs

In New York magazine, Steve Hall lays out the good, bad, and the ugly of cancer-drug economics. Warning: it is mostly bad and ugly.

The pharmacist e-mailed the numbers, and Saltz stared at the figures on his computer screen. Zaltrap, the drug that was extremely similar to Avastin, cost roughly $11,000 a month. (And because that extra 42 days wouldn’t be possible without taking the drug for, say, seven months before—which was roughly what was happening in clinical trials—the price for that six-week life extension could be as high as $75,000.)

“Wow,” he said to himself, “that’s a deal-changer for me.”

That may not seem like a heretical statement, but the unspoken rule in American health care is that doctors should never consider the cost of a medicine that might be beneficial to patients. When the FDA approves a new cancer drug, it analyzes safety and effectiveness only. Medicare is obliged to reimburse payment for the drug, and private insurers in most states must cover the cost. Any doctor who considers cost—or the value of a costly drug—risks being accused of “rationing” health care.

How Does that Steak Frites Happen?

If you want to remind yourself what a really good magazine article can be, check out Willy Staley‘s N.Y. Times Magazine piece “22 Hours in Balthazar.” Balthazar is a SoHo restaurant that’s been around long enough to be an institution but is still good enough to inspire devotion from scene-setters, tourists, and locals alike. How?

That’s the question the article (and photographs) answer, in an elegant and fact-filled manner. For instance:

For now, everything is quiet at Balthazar. The last guests from the night before left just a few hours ago, and the nighttime porters are still finishing their thorough scrub of the restaurant. But the delivery trucks are starting to arrive all over again, idling on Crosby. Men in lifting belts wheel hand trucks stacked high with food from across the globe: 80 pounds of ground beef, 700 pounds of top butt, 175 shoulder tenders, 1 case of New York strips, all from the Midwest; 5 pounds of chicken livers, 6 cases of chicken bones, 120 chicken breast cutlets; 30 pounds of bacon; 300 littleneck clams, 110 pounds of mussels from Prince Edward Island, another 20 pounds from New Zealand, 50 trout, 25 pounds of U10 shrimp (fewer than 10 pieces per pound), 55 whole dorade, 3 cases of escargot, 360 Little Skookum oysters from Washington State, 3 whole tunas, 45 skates, 18 black sea bass, 2 bags of 100 to 120 whelks, 45 lobster culls. That’s just the fish and meat order.

Some Evidence on the Relationship Between Copyright and Profit

How do copyright laws affect creativity? Do stronger laws increase profitability — and, therefore, do they increase creativity? If musicians/filmmakers/authors/software designers/etc. etc. etc. don’t have the strong incentive of copyright protection, will they create less or inferior work?

These question are both broad and long; many great minds have wrestled with them, and will continue to do so. Our recurring guest bloggers Kal Raustiala and Chris Sprigman regularly discuss copyright; Levitt touched on it here, and we discussed copyright protection in this podcast.

Now, in a new working paper (abstract; PDF) called “Copyright and the Profitability of Authorship: Evidence from Payments to Writers in the Romantic Period,” Megan MacGarvie and Petra Moser take up the argument: 

Scott Turow, President of the American Authors’ Guild, warned that regimes that weaken copyright, such as digital piracy may cause the “slow death of the American author” (Turow 2013). Empirical analyses of file sharing, however, reveal no significant effects on the quantity or quality of recorded music (Oberholzer-Gee and Strumpf 2009; Waldfogel 2013), which suggests that the importance of copyright protection may be overstated.

Homosexuality Is Undercounted; So Is Homophobia

That is the argument made in a new paper (abstract; PDF) by Katherine Coffman, Lucas Coffman, and Keith Marzilli Ericson, entitled “The Size of the LGBT Population and the Magnitude of Anti-Gay Sentiment Are Substantially Underestimated”:

Measuring sexual orientation, behavior, and related opinions is difficult because responses are biased towards socially acceptable answers. We test whether measurements are biased even when responses are private and anonymous and use our results to identify sexuality-related norms and how they vary. We run an experiment on 2,516 U.S. participants. Participants were randomly assigned to either a “best practices method” that was computer-based and provides privacy and anonymity, or to a “veiled elicitation method” that further conceals individual responses. Answers in the veiled method preclude inference about any particular individual, but can be used to accurately estimate statistics about the population. Comparing the two methods shows sexuality-related questions receive biased responses even under current best practices, and, for many questions, the bias is substantial. The veiled method increased self-reports of non-heterosexual identity by 65% (p<0.05) and same-sex sexual experiences by 59% (p<0.01). The veiled method also increased the rates of anti-gay sentiment. Respondents were 67% more likely to express disapproval of an openly gay manager at work (p<0.01) and 71% more likely to say it is okay to discriminate against lesbian, gay, or bisexual individuals (p<0.01). The results show non-heterosexuality and anti-gay sentiment are substantially underestimated in existing surveys, and the privacy afforded by current best practices is not always sufficient to eliminate bias. Finally, our results identify two social norms: it is perceived as socially undesirable both to be open about being gay, and to be unaccepting of gay individuals.

Are You Male, With a Job in Finance or Economics, and Want to Get on a "Wilderness Experience" TV Show?

Then today is your lucky day. Here’s a request we received from friends at a TV production company:

We’re casting the first season of Enter the Wild, an inspiring documentary series for a major cable network.  In the show, a diverse group of real people takes an outdoor survival course taught by one of the country’s most acclaimed wilderness experts.

It’s not a competition show. It’s not Survivor. The series will follow participants as they engage in a fully immersive, three-week course.  Our hope is that everyone will walk away not only with life-saving skills, but a new perspective on their lives and their relationship with nature.

We’d love to include a the point of view of a male with a work background in financial markets or economics in this wilderness experience. You can apply or get more information at our website.

A “casting treatment” from the company gives further information about the types of characters they are looking for. If I were a young anthropology researcher, I would be all over this thing — for what it says about the people who make, watch, and appear on modern TV. Here are a few of my favorites:

Should We Stop Children From Learning to Cheat?

A Freakonomics Radio listener named Sandra Elsen writes:

Today, I went to my son’s kindergarten.  He attends the local International School (what the Realtor described as the “Hippy-Dippy” school, lol), in a semi-rural area, just outside of the city in a middle-class town.

There, I was asked to help them learn a new game. The concept was simple:  a six-sided block had three 1’s and three 2’s marked on each side.  They had to trace the number that was rolled on their worksheet.  Roll, trace.  Once five of one number was achieved, either the firetruck or the firefighter (pictured at the bottom of the sheet) “won.”  The teacher indicated it was a “race” to see which picture would win.

Should H&R Block Hire Models to Increase Charitable Giving?

Our recent podcast “How to Raise Money Without Killing a Kitten” represented the launch of a fund-raising campaign for Freakonomics Radio. Let me say a few things about the campaign:

1. Wow! Listeners have so far responded way, way, way better than Levitt predicted they would in the podcast — so: 1a) Thanks!; and 1b) Nice job in proving a pretty smart guy very wrong.

2. Some of your comments and e-mails noted that WNYC’s fund-raising site doesn’t allow for contributions via PayPal, text, Flattr, Bitcoin, etc. That is true. Hopefully some of these avenues will be added over time. Some of you also noted that the podcast already has advertising, so why are we also asking for contributions from listeners? Good question. Short answer: WNYC is the funding producer of our podcast, and as such is responsible for paying all our producer and engineer salaries, studio time, field-recording costs, music-licensing costs, bandwidth, and a million other things, like the transcription of interviews (for every minute of talking that ends up in the podcast, we’ve probably got about five minutes of interview tape). We are grateful for the advertisers on our podcast, but that revenue is not nearly enough to produce the podcast. That’s why we came to you, our listeners, for additional support.

Which Foods (and Drinks) Get Better as You Eat More, and Which Get Worse?

A reader named Robb Stokar wrote in with the following question: “Which foods and/or drinks have the greatest diminishing marginal returns and which have the greatest increasing marginal returns?”

Wonderfully, Robb answered the question himself:

Diminishing food:  pancakes. Those first few bites of syrup-y and butter-y goodness are like angels singing. Then, about 1/2 way through, finishing the stack becomes a chore. And if you actually finish the stack, hello food coma. (Credit for the origin of this idea goes to my brother, Jason.)

Diminishing drink: Bloody Mary. First few sips are great, but by the bottom of the glass much of the spice has settled and you get a watery mouthful of pepper and celery salt.

Increasing drink: wine or whiskey, provided very little ice. Wine is self-explanatory, but some advocates say a little water “opens up” the whiskey and a cooler temperature eliminates that alcohol “bite.” I agree.

Increasing food: Indian or something similarly spiced. I believe that with each successive bite, the diner gets a better flavor profile and you can fully appreciate the dish.

The Retraction Penalty

In a new working paper called “The Retraction Penalty: Catastrophe and Consequence in Scientific Teams” (gated), Ginger Zhe Jin, Benjamin Jones, Susan Feng Lu, and Brian Uzzi explore a fascinating research question:

What are the individual rewards to working in teams? This question extends across many production settings but is of long-standing interest in science and innovation, where the “Matthew Effect” [a.k.a. “the rich get richer and the poor get poorer” suggests that eminent team members garner credit for great works at the expense of less eminent team members. In this paper, we study this question in reverse, examining highly negative events – article retractions. Using the Web of Science, we investigate how retractions affect citations to the authors’ prior publications. We find that the Matthew Effect works in reverse – namely, scientific misconduct imposes little citation penalty on eminent coauthors. By contrast, less eminent coauthors face substantial citation declines to their prior work, and especially when they are teamed with an eminent author. A simple Bayesian model is used to interpret the results. These findings suggest that a good reputation can have protective properties, but at the expense of those with less established reputations.

To me, this finding is a bit surprising at first glance but, upon second glance, not really — but still fascinating.

If you are even a little bit interested in this topic and don’t know about the Retraction Watch website, you should. A few recent examples:

Why Don't More Men Pursue Female-Dominated Professions?

A reader named Albert Hickey writes:

I’m a father of three girls and I’m into technology. I keep hearing that there is a major bias toward men in STEM (Science, Technology, Engineering and Maths) at college and in the workforce.  I also regularly see blog posts, videos, interviews and podcasts where women are discussing how this is not right and that we need to have more equality in STEM. All good and more women in tech would be a good thing as women are major users of technology.

But it struck me that I have near heard of men fighting for more men to study traditionally female-dominated subjects or jobs like primary-school teacher, nurse, PR officers and therapists.

Why are women fighting for more women to do STEM while men are not fighting for more men to be therapists?

My quick response to him:

I’m guessing it’s b/c of the wage differential but you are right, it’s worth asking.

In Praise of the Music in Freakonomics Radio

I think that our engineer/mixmaster David Herman does a fantastic job of making Freakonomics Radio podcasts sound great (no matter what you may think of all the talking that interrupts the music and other audio effects).

But there is of course a lot of heterogeneity in personal preferences. Here’s an e-mail we just received from a listener:

Heard your show for the first time yesterday on Tipping.  Loved all the speaking clips and analysis. HATED the musical interludes so much that we (my husband, kids and I) cannot fathom ever listening again unless they are removed. They gave us a bad headache and were so distracting from the content that we had to turn the show off before the end.  Please consider removing them. Thanks.

Afraid we just lost a family of listeners, as we won’t be removing all music from our episodes. Happy to say this is an uncommon complaint; much more common is an e-mail asking where to get hold of the music that appears. FWIW, every time we put out a podcast, the accompanying blog post includes a transcript of the episode which lists the music.

Who Wants a Haircut for $9.99?

The other day I was walking past this barber shop on Broadway in the upper 90’s. This sign caught my eye.

It made me wonder what kind of customer is willing to get a crewcut by an “apprentice barber.” Would you? Also, was there really an “apprentice barber” on standby only to handle the $9.99 cuts? Not likely. It did make me think back to when I was in grad school and needed a root canal, and took advantage of the cut-rate dentistry available at my school’s College of Dental Medicine. The root canal was performed by a student — it took many visits, was unbelievably painful, and kept me from returning to any dentist for several years.

Is Texting Good For Adolescents?

The short answer is yes, at least if the goal is to develop more offline friendships. That is the argument of Maria Koutamanis and co-authors in a study published in Computers in Human Behavior:

The first aim of this study was to investigate whether instant messaging (IM) influences adolescents’ ability to initiate offline friendships. The second aim was to study the validity of two underlying mechanisms that may account for this relationship: (a) the opportunities offered by IM to communicate with a variety of people, and (b) to disclose intimate information. A three-wave longitudinal study was conducted among 690 Dutch adolescents (10–17 years old). Results show that adolescents’ IM use increased their ability to initiate offline friendships over time. Furthermore, IM use indirectly increased adolescents’ ability to initiate offline friendships through the diversity of their online communication partners. These findings suggest that adolescents can practice social skills online and learn to relate to a variety of people, which, over time, may increase their ability to initiate offline friendships.

How Much of Our Success Should We Claim Credit For?

Our most recent podcast was called “Would a Big Bucket of Cash Really Change Your Life?” It showed that the winners of a 19th-century land lottery did not appear to convert their windfall into intergenerational wealth. This challenges the modern argument that cash transfers are one of the most effective ways of helping a poor family escape poverty — and, therefore, as we said in the podcast, might be seen as a depressing conclusion.

Judd Campbell from Odessa, Texas, wrote in to dispute the depressing part, and offer some worthwhile commentary:

I just finished listening to the latest podcast about the Georgia land lottery in the 19th century. I actually found it not to be depressing at all.

Here’s why:

1. It would be depressing to me to know that poverty has existed into modernity, and the solution would be a simple one-time transfer of wealth. Surely, we could have figured that out by now and eliminated poverty. Clearly, the issue is more complex than that, and thus we have an excuse for not developing a solution. Yet.

2. While I don’t consider myself wealthy, I do make a healthy salary and live in a comfortable home with 4 kids. There are a couple of things that I believe about my life, that may or may not be logical or factual, but provides me comfort:

a. My financial success is not due to my parents. I did it on my own. I did grow up in a comfortable home with loving and supportive parents, my father has a master’s degree, and I appreciate what they have provided me. But in my gut I feel like I achieved my own success. This podcast was uplifting, because it seems to confirm that I am responsible for my own success.

b. On the other hand, I feel like my financial success will help my children be financially successful. Even though I don’t give my parents credit for my success, I believe that I can influence my children to be successful.

Tom Collins Has Spoken

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 …
