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:



Are Fake Resumes Ethical for Academic Research?

“Audit studies” have been popular in labor economics research for 10 years.  The researcher sends resumés of artificial job applicants in response to job openings. Typically there is a crucial difference in some characteristic of the person that indicates a particular racial/gender/ethnic or other group to which one person within a pair of resumés belongs while the other does not.  The differential response of employers to the difference in the characteristic implied by the resumés is taken as a measure of discrimination in hiring.

Is this ethical? 



Incentivizing Peer Reviewers

It really annoys me! I review papers for scholarly journals and, if I agree to undertake the task, have never taken more than six weeks to get the job done. But sometimes my own papers are held by scholarly journals for a year, as the journal waits on reviews by one or more delinquent reviewers.



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

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



Is the U.S. High School Graduation Rate Worse Than We Thought?

That’s the assertion made by James Heckman and Paul LaFontaine in a new working paper called “The American High School Graduation Rate: Trends and Levels.” Here is their abstract: This paper uses multiple data sources and a unified methodology to estimate the trends and levels of the U.S. high school graduation rate. Correcting for important biases that plague previous calculations, . . .



Mozilla Gets Freaky

For the last few years I’ve been trying to convince businesses to run experiments in order to learn how to do things better. Why is it that experimentation is the gold standard in science, but rarely exploited in corporations? My own hunch is that the main reason is what economists call “path dependence” — in other words, businesses don’t run . . .



Love Your Job? That Doesn’t Mean You’re Better at It

The conventional employer wisdom has always been that a happy employee is a more productive employee. Countless dollars are spent every year on initiatives to raise employee morale, create camaraderie in the workplace, and eliminate practices that could lead to a hostile work environment, all so that companies can boost their retention rates and productivity levels. So is it really . . .



Why Are Women More Likely to Be Obese Than Men?

In almost all countries, women are more likely to be obese than men. The economists Anne Case and Alicia Menendez set out to learn why, using data collected from a township outside of Cape Town, South Africa. Here’s what they determined: 1. “Women who were nutritionally deprived as children are significantly more likely to be obese as adults, while men . . .



The Economics of Mosquitoes

You might not think that mosquitoes would be a great topic for economists, but two recent papers prove otherwise. I grew up in Minnesota. The state motto is “The Land of 10,000 Lakes,” which meant that there was never a shortage of mosquitoes. When I was a kid, I wasn’t allowed to go in the backyard in the summer because . . .

What’s the Most Important Psychological Experiment That’s Never Been Done?

That is the very good question posed on the British Psychological Society’s research blog. The answers, provided by leading psychologists, are even better. In many cases, it’s not that the experiments haven’t been done, but that they can’t be, often for ethical or practical reasons. But even if the proposed experiments are only thought experiments, they are well worth reading. . . .



More Evidence on the (Lack of) Impact of School Choice

There is no policy economists love more than school choice. Milton Friedman was an early proponent. The idea certainly makes sense: if parents have the ability to choose the best schools for their children, outcomes should improve through both the better matching of kids to specific schools and the resulting competition that would force schools to develop their programs.

The Debate on Female Happiness Heats Up

I blogged a few days back about the interesting new paper by Betsey Stevenson and Justin Wolfers analyzing trends in happiness by gender, and finding statistically significant reductions in how happy women are relative to men. Elsewhere on the Internet, the paper has drawn the ire of a number of bloggers. Stevenson and Wolfers have fired back on Marginal Revolution, . . .



Why Are Women So Unhappy?

I saw Justin Wolfers a few weeks back, and I joked with him that it had been months since I’d seen his research in the headlines. It didn’t take him long to fix that — he and his partner in life and economics, Betsey Stevenson, made the news twice last week. The first time was in the form of an . . .



Do Newspapers Use Economic News to Sway Public Opinion?

As Levitt has noted in the past, media bias is a hot topic among some economists. Typically the bias is reflected in a paper’s reporting (as Dubner pointed out here). But can newspapers also influence public opinion based on their coverage of economic matters? That’s the question addressed in the working paper “Partisan Bias in Economic News: Evidence on the . . .



The Science of Passing the Bar Exam: Does First-Year Torts Really Matter?

Every year, thousands of law school graduates leap into the nerve-wracking and costly process of preparing for the bar exam. The bar consists of two days of testing (three in California) on memorization and comprehension of specific areas of law. Failure is hardly uncommon: various estimates place the passage rate at roughly 70 percent, while the failure rate in California . . .

Hatred and Profits: Getting Under the Hood of the Ku Klux Klan

That is the title of my latest academic working paper, written with Roland Fryer. It details the rise and fall of the Klan in the 1920s. Incredibly, the Klan had millions of members at that time, and most of them were reasonably well-educated. Based on a variety of data sources, we argue that, despite its size and education levels, the . . .



Are Health, Wealth and Happiness Linked Worldwide?

Levitt and Dubner have blogged quite a bit about the growing literature on happiness studies. Meanwhile, the media has been abuzz recently over the relationship (or possible lack thereof) between happiness and wealth. Enter Angus Deaton, a professor of economics and international affairs at Princeton. Deaton has a published new paper, “Income, Aging, Health and Wellbeing Around the World: Evidence . . .



The Most Surprising Thing I Learned Today

The most surprising thing I learned today comes from the opening paragraph of a paper by Anne Case and Christina Paxson: In late 19th Century Europe, adult height was attained at age 26. This is just one reminder of how radically life has changed in the last 100 years. At least in the developed world, we have moved from a . . .



There Is Hope For Economics: The AC/DC Paper Was a Joke

I am delighted to report that the economics paper on AC/DC I blogged about yesterday was meant as a joke. It takes a lot of work to run an experiment on real people, just for a gag paper. It turns out they meant to play the same AC/DC song in both treatments, but made a mistake and accidentally played two . . .



It’s All Semantics

For reasons that may not make sense to anyone else, I recently performed a Google search for “They Might Be Giants” and “Belly Button.” This was the second hit: a paper by a Stanford linguist named David Beaver (that’s not an aptonym, is it?) called “Have You Noticed That Your Belly Button Lint Colour Is Related to the Colour of . . .



The FREAKest Links: iPhones May Be Hazardous to your Health Edition

Via Marginal Revolution: In his quest to explain the male-female wage gap in business, academia, and other fields, the economist M.

Paserman argues that male athletes are generally more adept at handling high-pressure situations. With iPhone frenzy reaching a peak, . . .



Eating Too Much Leads to More Gas

Given my father’s medical specialty, you might think I’m referring to intestinal gas. Actually, though, I am talking about the kind of gas you put in your fuel tank. In a recent study, researchers at the University of Illinois have calculated how much extra gasoline is being used each year because Americans weigh more and thus require more fuel to . . .

Included in the hubbub leading up to the final Harry Potter installment is a prediction exchange in which participants bet on whether Harry lives or dies — although betting has now been influenced by an anonymous Web spoiler claiming insider knowledge that the hero doesn’t meet an untimely doom.

Parking Tickets and Corruption, Take Two

Last year we blogged about the fascinating study written by economists Ray Fisman and Ted Miguel analyzing the patterns of parking violations among diplomats to the United Nations in New York. They find that diplomats from high corruption countries have more unpaid parking tickets, as do diplomats from countries that are more anti-American. Armed with that information, try to guess . . .



The FREAKest Links: Happiness, Gaming, and Congestion Edition

We’ve written quite a bit about the science of happiness. Now a study by Nattavudh Powdthavee, a research officer at the University of London’s Institute of Education, has taken the debate a step further, assigning monetary values to intangibles like good health and better relationships. He argues that more time with loved ones merits a $179,000 happiness-equivalent raise, while marriage . . .

Does the Death Penalty Really Reduce Crime?

Associated Press reporter Robert Tanner writes an article today stating that evidence strongly supports the conclusion that the death penalty reduces crime. As with most media coverage of controversial issues, there is a paragraph or two in which the other side makes its case.
