Customers, Social Media and the Internet's Silent Majority

A new article in MIT’s Sloan Management Review written by marketing professors Wendy W. Moe, David A. Schweidel and Michael Trusov sheds some light on how people use the internet to interact with products and with each other, specifically in terms of what spurs and defines social media comments. In recent research, the authors examined the comment ratings and sales of a popular unnamed company, studying 2,436 individuals writing about 200 products. They ask: “[H]ow accurately do these conversations represent the true underlying sentiment of a product’s customers?” Here’s what they found:


Economics Run Amok: What's Your Price?

Freakonomics is no stranger to studying prostitution, as discussed in Superfreakonomics.  We are slightly less familiar, however, with a gray area of prostitution — “dating websites” that connect rich customers with attractive poor customers.  Though these are by no means a new phenomena, a website has recently come to our attention that uses a dating website platform to ask what we all wonder about in one context or another: what’s your price? Whatsyourprice.com auctions off dates and claims to be inspired by the charity dating model.  It is divided into two halves: “Date Generous People” and “Date Attractive People” — apparently you’re either looking for one or the other.  Upon a cursory read, the generous users seem to be overwhelmingly male, and the attractive users overwhelmingly female (and pictured in bathing suits).   Each profile includes an “About Me” section and a “First Date Expectations” section. Several “attractive” members, it should be noted, specify that they will not fly Economy Class.


Rules of The Game

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
Michael asked:

“The best swordsman does not fear the second best, he fears the worst since there’s no telling what that idiot is going to do.”


Radio in Progress: Boo!

A few months ago we asked readers a basic question: “Do you boo?” Judging by the number (and nature) of comments the post solicited, the answer is yes. The question was asked as part of an upcoming Freakonomics Radio episode that’s all about booing. To borrow the words of one of our guests, writer Robert Lipsyte, we ask: Is booing verbal vandalism, or is it one of the last true expressions of democracy?
For the audience at the Apollo Theater in Harlem, it’s the latter. We recently visited for its talent showcase, Amateur Night. There, booing—and cheering—is a way of voting, to decide who advances to the next round of competition.


Get Your Free Sperm Here!

The Daily Beast reports on an interesting phenomenon: sperm donors who donate for free.  One couple, stymied by the $2,000-and-up cost of acquiring sperm the usual way (sperm bank), started exploring alternative options online…


Can Google Searches Predict Stock Price Performance?

A recent study in the Journal of Finance by Zhi Da and Paul Gao of the University of Notre Dame shows that data from public Google searches can be used to beat the stock market by up to ten percentage points per year. Similar findings were released last month by researchers at the University of Kansas.
The Notre Dame authors argue that the frequency of Google searches received by a stock (its SVI number) is a better, more direct method of measuring investor attention (a precursor to buying the stock) than traditional, indirect methods of measurement, such as news and advertising expense.


Paying the Rent After the Pink Slip

A recent national survey indicates that “[o]ne in three Americans would be unable to make their mortgage or rent payment beyond one month if they lost their job.” Even higher-income households would find themselves in trouble quickly: “Ten percent of survey respondents earning $100K or more a year say they would immediately miss a payment.”
Even more Americans — 61 percent — wouldn’t be able to pay the rent or mortgage after five months of unemployment. Given the current state of the economy, it’s perhaps wise to heed Suze Orman‘s 2008 advice on this blog — she recommended an eight-month emergency savings fund.


FREAK-est Links

This week, the suffering French nobility; adjusting for crime inflation, is New York really safer? Climate concerns: getting closer to that garden hose to the sky? And two signs of the times: Sesame Street debuts an impoverished Muppet, and Friendly’s goes bankrupt.


Should College Football Be Taxed? Bring Your Questions for Allen Sanderson

Allen R. Sanderson is an economist at the University of Chicago who enjoys, among other things, writing about sports. Some of his past work includes pieces on the puzzling economics of sports, why ties should be allowed in baseball, and how football highlights America’s least flattering features.
Sanderson’s most recent piece comes from the November 2011 issue of Chicago Life magazine, entitled “Taxes and Touchdowns.” In it, Sanderson argues in favor of imposing “steep” taxes on college football (and perhaps basketball) and that a college sports tax should be seen as the fifth sin tax, next to taxes on alcohol, cigarettes, gasoline and fat/sugar. And he’s not just talking about taxing certain aspects of college football; he’s talking about taxing the whole shebang: advertising, television broadcasts, logo merchandise sales, gate receipts. And then using that money to help support those “student-athletes” who don’t make it pro in their effort to finish up their education.


Why Gun Traffickers Should Live in Arizona

A new study by Brian Knight, an economist at Brown, explores the flow of the illegal firearm market in America and compares the source of guns used in crimes to gun laws in and around that state.
How big is the market for illegal firearms? Pretty big. Knight writes: “ATF investigations into tracking between July 1996 and December 1998 identify over 84,000 firearms that were diverted into this secondary market (ATF, 2000).” Meanwhile, each state in America legislates its own gun laws, resulting in cross-state externalities. For example, Knight cites anecdotal evidence showing that a gun purchased legally in Virginia for $150 – $200 typically resells in New York City for $500 – $600. This is the sort of thing that keeps Michael Bloomberg up at night.
Here’s the abstract:


Confessions of a Steve Jobs Fanboy

This is a cross-post from James Altucher‘s blog Altucher Confidential. His previous appearances on the Freakonomics blog can be found here.
I saw the news this morning when I looked at my iPad. Whenever I wake up, the first thing I do, before even going to the bathroom, is turn on the iPad and check the news. My heart sank when I saw the headline: Steve Jobs, dead at 56.
From my first Apple product (an Apple II+), to doing all my homework in college on the first Macintosh, to reading this news on my iPad, to typing this sentence on my Macbook Air, so much of my life has been influenced and changed by this man. Very sad day. My question for readers (please answer in the comments section) is: what was your first Apple product?
And now, here’s an essay I’ve written about Jobs:
I was standing right next to Steve Jobs in 1989, and felt completely inadequate. The guy was incredibly wealthy, good-looking: a nerd super-rockstar who had just convinced my school to buy a bunch of NeXT computers, which were in fact the best machines to program on at the time. I wanted to be him, badly.


Explaining the Black-White Wage Gap

As of 2010, black men in America earned 74.5 percent of a typical white man’s wage; black women earned 69.6 percent. A new paper from Harvard’s Roland Fryer (certified genius), Princeton’s Devah Pager and Jorg L. Spenkuch of the University of Chicago examines some of the factors driving the black-white wage gap.
Using data from unemployed workers in New Jersey who sought employment for up to 12 weeks, the authors show that racial discrimination accounts for one-third of the wage difference. They also estimate that blacks have a 7 percent lower reservation wage than their white counterparts at a comparable job that demands a comparable skill level. Fryer and his colleagues control for skill level by measuring the job applicants’ wage at their previous job against the wage they were seeking.
Here’s the abstract:


Is Mitt Romney Less Well-Known Than He Was in 2007?

According to a new Pew Research Center poll, while 54 percent of Americans are able to name at least one GOP presidential candidate, the leading candidates aren’t named as often as in previous years. Only 27 percent of Americans named Mitt Romney and only 28 percent named Rick Perry. That’s below the same measure taken four years ago in October 2007, when 45 percent could name Rudy Giuliani and 30 percent could name Romney. So, well into his second campaign for president, Romney is now less well-known than he was four years ago, when he ran the first time around. Not exactly encouraging.
Also, it’s interesting that Perry is still more recognizable than Romney, despite having fallen in the polls recently — especially since Perry got into the race only about two months ago, and Romney’s been running for much of the last four years. Chalk it up to the Texas swagger versus consultant technocrat?


Immigration, Elasticity and Why Americans Won't Pick Onions (Yet)

A study released this week by NBER measures the elasticity of substitution between American workers and their immigrant counterparts — in non-economic speak, the study asks whether immigrants are good substitutes for equally skilled native workers. While some comparisons remain murky, it appears that non-native workers are actually “perfect substitutes” for equally skilled native workers. The authors write:

In terms of the elasticity of substitution between equally skilled immigrants and natives, we conclude that the OP data, correctly analyzed, imply that the two groups are perfect substitutes. In fact, by using a statistically valid set of regression weights and by defining the earnings of a skill group as the mean log wage of the group (rather than the unconventional log mean wage used by OP), we find that the OP data reveal an effectively infinite substitution elasticity. The evidence thus implies that native workers are exposed to adverse effects from immigration-induced increases in labor supply.

The study sheds some light on the thinking behind (and backlash against) Alabama’s court-upheld crackdown on illegal immigrants.


What if They'd Just Called it the iPhone 5?

Unless you’re living under a rock, you’re probably aware that Apple unveiled a new iPhone yesterday. At what turned out to be a relatively muted Apple product launch, it was new CEO Tim Cook‘s first chance at replacing Steve Jobs as product pitchman. It seems he did just fine.
The new iPhone is loaded with cool new features that the market was anticipating, with one exception: it’s not called the iPhone 5, it’s called the iPhone 4S.
By the time it became obvious that Cook wasn’t going to introduce anything called an iPhone 5, (about 1:50 pm EST yesterday), the stock price began to plummet pretty quickly, as you can see in the chart below. From 12:15 pm to 3:15 pm, the price dropped more than 6%. Also, note the spike in volume at the bottom.


Should I Quit My Job?

In our latest Freakonomics Radio podcast, “The Upside of Quitting,” we talk about strategic quitting. You can download/subscribe at iTunes, get the RSS feed, or read the transcript here.
One of the hardest things in life to quit is probably a career: what if you were great at your job, making decent money, but it’s just not what you want?
Dubner talks to a very interesting woman who was faced with such a choice, and how she came to her decision to just quit.
From the Freakonomics Radio live show in St. Paul, MN earlier this year (part of which was another podcast earlier this year), here’s the interview with Allie – with an animation by the talented Benjamin Arthur.


A Dad-or-Daughter Songwriting Contest

My daughter, Anna, spent a bunch of time this past summer writing songs. One thing led to another and we ended up coauthoring a song together. I have more than 50 academic coauthors, but this is the first time I’ve ever tried writing music with someone.
Is it easy for people to tell the difference between songs she wrote by herself and a song where I wrote most of the lyrics? Is it possible for a 52-year-old lawyer/economist to emulate the lyrics of a 14-year-old Gleek? I think a lot of people would have a surprisingly hard time. But the question is testable.
So today I’m announcing a contest where you could earn a chance of winning an iTunes gift card worth somewhere between $50-$500. To play, just click through and listen to these three songs – Friend Zone, Longer, & Your Way, and then leave a comment to this post or as a YouTube comment to one of the three songs saying: i) which of the three songs you think I coauthored; ii) identifying a line in that song you believe I wrote; and iii) identifying a line in that song you believe Anna wrote. Here they are:


Denmark Levies the World's First Nationwide Fat Tax

This week, Denmark begins a large-scale incentives trial of sorts by becoming the first country to impose a nationwide fat tax. From now on, foods in Denmark with saturated fat content above 2.3% will be taxed 16 Danish kroner ($2.87) per kilogram of saturated fat; which works out to a tax of about $1.28 per pound of saturated fat. The tax was reportedly preceded by weeks of Danes stocking up on items like butter, red meat and pizza.
The issue of taxing fatty or sugary foods (and more broadly, the effectiveness of behavioral nudges) has been a topic of repeated discussion on this blog. James McWilliams posted last December on studies which indicate that while taxing sugary sodas reduces consumption, others have shown soda taxes to be ineffective at reducing obesity rates. Proof, McWilliams argues, that taxing specific food items is ultimately ineffective, since consumers can simply substitute sugar from other non-soda sources.


How Will Peanut Price Hike Impact Related Items?

General equilibrium ain’t just peanuts. With the tremendous shortfall in the peanut harvest (a decline of 17%) due to the unusually dry weather in peanut-growing states, people are expecting a rise in the price of this main input of peanut butter to cause supply to shift leftward. Jif peanut butter expects to raise its price by 30% starting in November.
I doubt that its sales will go down much—I think the demand for peanut butter is fairly inelastic. But what about related markets? If everyone likes peanut butter and mayonnaise sandwiches as much as I do—if peanut butter and mayonnaise are complements—then we’ll see a leftward shift in demand for mayonnaise, and its price will decline. Have I held too much of the ceteris paribus, or not enough? Where should one stop?


Banana Arbitrage

Bananas are a popular topic on this blog. In February, a reader wrote in with this odd banana stand pricing phenomenon. And in 2008, Dubner explored the potentially tenuous economics of the far-flung fruit.
I’ve recently run across something similar to the banana stand case: the Starbucks closest to my apartment now sells bananas at the counter for $1 each, while right outside the door, a fruit stand sells them for 25 cents each, or 5 for $1. And the fruit stand bananas are always better looking than the ones at the Starbucks register.


News for Dieters: Old Habits Die Hard

If you’re trying to lose weight, making a small change might help. A new study (summarized by the BPS Research Digest) finds that using the non-dominant hand can significantly reduce the kind of habitual eating that many indulge in without even noticing.
Psychologists invited 158 subjects to watch movie trailers in either a movie theater or a university department meeting room and provided participants (some habitual popcorn eaters, some not) with either stale or fresh popcorn. They found that “in the cinema setting the habitual popcorn eaters ate just as much of the popcorn when it was stale as when it was fresh.


FREAK-y Stat of the Day: It's 2008 All Over Again

This Freaky stat comes courtesy of reader Benjamin Bias, who brought to our attention this oddity, as noted by Joe Weisenthal at Business Insider:
Yesterday, Oct. 3, 2011, the S&P 500 closed at 1,099.23.
Exactly three years ago, on Oct. 3, 2008, the S&P 500 closed at 1,099.23.
As if investors needed anymore reason to be nervous these days.


Do Lower Wages and Higher Unemployment Increase Voter Turnout?

A recent study by Kerwin Kofi Charles and Melvin Stephens Jr argues that increases in wages and employment reduce voter turnout in gubernatorial elections, though not in presidential contests.
From the abstract:

This paper argues that, since activities that provide political information are complementary with leisure, increased labor market activity should lower turnout, but should do so least in prominent elections where information is ubiquitous. Using official county-level voting data and a variety of OLS and TSLS models, we find that increases in wages and employment: reduce voter turnout in gubernatorial elections by a significant amount; have no effect on Presidential turnout; and raise the share of persons voting in a Presidential election who do not vote on a House of Representative election on the same ballot.


Author Steven Pinker Answers Your Questions

Last week we solicited your questions for author and Harvard psychology professor Steven Pinker on his new book, The Better Angels of Our Nature: Why Violence Has Declined. You responded quickly with more than 50 questions. Now, Pinker is back with his answers to 10 of them. The result is a fascinating discussion (exactly the kind we like to have around here) on the roots of violence, the rationale for wars of the past and what a decrease in violence says about modern society. As always, thanks to everyone for participating.

Q Any thoughts on the negative side effects of decreased violence? Overpopulation? More sedentary populations? Decreased role for survival of the fittest? Not to say that violence is preferable, just wondering about the downsides of peace. – BL1Y


Predicting the Nobel Prize

Next Monday, the Nobel Prize Committee will announce the recipient(s) of the 2011 Nobel Prize in Economic Sciences. If you think you know who’s going to score this year’s prize, head on over to Harvard’s Nobel Pool, “the world’s most accurate prediction market.”
Each entry will cost you $1; all entries and bets must be received by 11:59 PM on Sunday, October 9th. If you’re looking for inspiration, past predictions can be found here. And if you haven’t already, listen to our Freakonomics Radio podcast, “The Folly of Predictions,” to find out where we stand on the whole notion of predictions.
So Freakonomics readers, who are you betting on?


New Blog Explores Economics of Digital World: Digitopoly

Our friend Joshua Gans, along with some colleagues, has launched a new blog devoted to the economics of digitization called digitopoly.org. Here, in a guest post, he explains the origins of the site, and what it’s all about.
 
Digonomics
By Joshua Gans
Some of the most popular blogs are tech blogs (Gizmodo, Engadget, TechCrunch) or blogs that place a tech perspective on social commentary (e.g., BoingBoing). And, as we know, economics blogs also tend to be popular. What was missing though was a blog devoted to the economics and competitive issues that arise in the digital age. What’s more, thanks to the NBER’s new Program on the Economics of Digitization (funded by the Sloan Foundation), there is a wealth of new research in this area. That’s how we came to setup a blog devoted to digital issues from an economics perspective.


School Bus Ads: Good Use of Space, or Crass Commercialization?

Facing a combined budget deficit of more than $100 billion for fiscal year 2012, a lot of states are cutting education budgets to make ends meet: laying off teachers, reducing hours and services. But recently, a handful of states have found a creative way to raise revenue from public education by putting advertisements on school buses.
Seven states, the latest being New Jersey, now allow school districts to sell ads on the sides of public school buses. Florida is currently considering it. So is Guam apparently. There are even two companies, Alpha Media and Steep Creek Media (both in Texas), that specialize in nothing but school bus advertisements.


Goodbye, Turkey Sandwich

Last week, I was out in Chicago for a couple of days working with Levitt. We had lunch at the Booth School cafeteria (with its great soda design) — or at least we tried to have lunch. There was a nice-looking case of sandwiches, and I asked the guy behind the counter for one of the turkey-cranberry sandwiches.
“No,” he said. “I can’t sell it to you.”
“Why not?” I asked.
“We’re closing. I can’t sell it to you.”
It was about 2:32 p.m. on a weekday afternoon. The sandwich I was eyeing was one of maybe 15 or 20 in the case. And then the guy behind the counter drags over a big trash can and throws my sandwich into it, and then all the other sandwiches too. It might have been my imagination — or maybe just hunger — but he seemed to take delight in throwing away the food for which I was ready to pay full price.


Study: Early Bedtimes Keep Kids Slimmer

A new study out of Australia shows that children who go to sleep early and wake up early are less likely to be obese. The results, published in the Oct. 1 issue of the journal Sleep, indicate that it’s not so much the amount of sleep kids get, but the times at which they get it that has the biggest impact on their weight.
