Today is the first day of the rest of our blogging lives. For 3.5 years, this blog has lived at NYTimes.com, very happily for the most part. But as time passed, we became eager to take the blog indie again, and unite it with the other stuff we’ve been working on.
Ian Ayres has long advocated the use of commitment contracts in achieving dieting and weight loss goals. Alan M Garber and Jeremy D Goldhaber-Fieber write about their research on commitment contracts and exercise.
In celebration of its 100-year anniversary, the American Economic Review asked six “eminent economists” (Kenneth J. Arrow, B. Douglas Bernheim, Martin S. Feldstein, Daniel L. McFadden, James M. Poterba, and Robert M. Solow) to select the journal’s top 20 papers ever published.
While arcades in the U.S. (and most of the rest of the world) are fading, they’re still strong in Japan. Why? According to Mark Cerny, an arcade gaming expert, it has to do with currency.
A new study finds that drug use in Britain is declining amount young adults: “According to figures released by the NHS in January, based on data from the British Crime Survey, the number of adults in England and Wales who used illicit substances in 2009-10 – 8.6% – was the lowest recorded since the study began in 1996. Among 16-24-year-olds, the picture was the same, with just 20% saying they had taken drugs in the previous year – another record low, and a third lower than the proportion 15 years ago.”
Sure, studying transportation is important if you need to find the best route to the hardware store. But you might be surprised to know that transportation study might have other uses, like enlightening you about the most profound philosophical mysteries of the universe. For example, transportation might just tell us some surprising things about the degree to which we truly have free will.
A reader named Sarah Johnson, who is passionate about crocheting, noticed something curious about the demographics of a user-rated knitting-and-crocheting website called Ravelry. Sarah is graduating from high school in June, and plans to major in psychology and pre-med. She writes: “I joined a free site for knitters and crocheters called Ravelry. As far as a little Internet research goes, it’s one of the biggest knitting and crochet sites out there, with over 1 million members. CrochetMe, another big site with comparable features, has 224,000 users. Crochetville, a large crochet forum, has only 46,000 members as of today. 414,974 people like ‘knitting’ on Facebook. By comparison, only 5,560 people like ‘crochet.'”
At a seminar in Germany last week, a statistical difference illustrated a crucial E.U.-U.S. difference in politico-economic attitudes. In the U.S., we define the poverty line as absolute: three times the income needed for a minimally nutritious food budget. In Europe, the poverty line is based on relative income, typically 50 percent of the median income.
Cholera, long considered “a disease of filth carried in sewage,” is a little more complicated than that, writes the science journalist Sonia Shah. “[R]esearch on cholera’s natural habitat and links to the climate have revealed a revolutionary new understanding of the disease as one shaped just as much by environment, hydrology, and weather patterns as by poor sanitation,” writes Shah. “And as temperatures continue to rise this century, cholera outbreaks may become increasingly common, with the bacteria growing more rapidly in warmer waters.”
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 research.
A new study finds that parents in newer, “frontier” states choose less-common baby names than parents in older states (like the original 13). “In New England states, more babies were given the most popular boys’ and girls’ names than they were in frontier states – those in the Mountain West and Pacific Northwest. Statistical analyses showed the longer ago a state had achieved statehood, the more likely it was to have a higher percentage of people with one of the top 10 most popular baby names. The results held even after the researchers accounted for other factors that might impact baby-name choices, including population density, ethnicity of a state and median income.”
Last week, Michigan’s Save-to-Win program, the sort of “no-lose lottery” we discussed in a two-part podcast, announced its second winner. Charmain Hanners of Alpena Alcona Area Credit Union is this year’s lucky winner of $100,000.
My Department chairman is mystified: You would think that with the crisis in public budgets, the demand for new economics faculty members would have shifted leftward. Similarly, with graduate students having delayed entry into the market, the supply of new Ph.D.s this year would have shifted rightward. Together, these changes should have lowered the price (wage) that the market pays new Ph.D.s.
Dean Karlan is a professor of economics at Yale; president and founder of Innovations for Poverty Action; a research fellow at the M.I.T. Jameel Poverty Action Lab; and co-author, with Jacob Appel, of More Than Good Intentions. He’s guest-blogging for us about charitable giving. This week, he writes about Swipegood.
In this week’s New Yorker, John Cassidy asks whether Islam may be to blame for slow economic growth in the Arab world.
We’ve addressed the rent-splitting problem before. Now, Harvard astrophysics grad student Jonathan Bittner is seeking to solve the problem with a rent calculator to help roommates approximate fair prices in this “market.”
The Salina Journal, a daily newspaper in Salina, Kansas, has published a final exam that was given to local eighth-graders in 1895 (via this friendly website). (“It was taken from the original document on file at the Smoky Valley Genealogical Society and Library in Salina, KS.”)
I’ve been watching developments in the Middle East and Northern Africa closely. It can be hard to keep track of it all. Fortunately, the prediction markets at InTrade provide a useful barometer.
Readers of this blog may be surprised to learn that in 2005 I coauthored an article with Jonathan Macey which made explicit predictions about the future of democratization in Egypt. In 2005, Jonathan and I wrote: “We also posit that economic reform will bring increased pressure for democratization in countries such as Egypt and Syria. For this reason, economic reform of the kind we discuss in this Article (simplifying and reducing the costs of business formation) will be a good “leading indicator” of political leaders’ real interest in implementing meaningful democratic reforms that go beyond mere public relations gimmicks.”
Watson may have triumphed at Jeopardy!, but Brian Christian examines computer intelligence more closely in the Atlantic. Christian recently participated in the Turing Test: “I will sit down at a computer and have a series of five-minute instant-message chats with several strangers. At the other end of these chats will be a psychologist, a linguist, a computer scientist, and the host of a popular British technology show. Together they form a judging panel, evaluating my ability to do one of the strangest things I’ve ever been asked to do. I must convince them that I’m human.”
Obesity is far from just an American problem. These nifty maps from the Economist display average BMI for males around the world in 1980 and 2008, and the percentage change.
The IBM supercomputer named Watson has beaten two Jeopardy! champions in a three-night marathon. The computer was awarded a $1 million prize, but the BBC reports that “the victory for Watson and IBM was about more than money. It was about ushering in a new era in computing where machines will increasingly be able to learn and understand what humans are really asking them for. Jeopardy is seen as a significant challenge for Watson because of the show’s rapid-fire format and clues that rely on subtle meanings, puns, and riddles; something humans excel at and computers do not.”
A while back, we did a Freakonomics Radio program asking why the NFL hasn’t (yet) put advertising on its players’ jerseys. One person we spoke with was Michael Neuman, then of Amplify Sports and Entertainment and now of Horizon Media. Neuman and Horizon have just released a report that tries to put a firm dollar figure on jersey sponsorship.
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 research.
Kal Raustiala, a professor at UCLA Law School and the UCLA International Institute, and Chris Sprigman, a professor at the University of Virginia Law School, are experts in counterfeiting and intellectual property. They have been guest-blogging for us about copyright issues. This week, they write about a recent Jeff Koons controversy.
One session at the recent AEA meetings addressed “popular economics,” with a panel including Diane Coyle, Robert Frank, Steve Levitt, and Robert Shiller. (Shiller wrote a bit about it on Slate.) Many interesting things were said. To me, the most interesting was that Frank is writing a book arguing that Charles Darwin, more so than Adam Smith, is the true forefather of modern economics. (He has already written a Times column on the topic.)
Ordering your significant other to ignore the attractive person at the next table might backfire, according to a new study.
How much would you pay to avoid regrets? A new study (gated) by psychologists Niels van de Ven and Marcel Zeelenberg finds that people are willing to forgo direct benefits in order to avoid regrets.
Last week, we solicited your questions for Paula Szuchman and Jenny Anderson, co-authors of the new book Spousonomics: Using Economics to Master Love, Marriage, and Dirty Dishes.
Here are their answers, covering everything from sex to divorce to … gulp … apology. Thanks to all who participated, especially Paula and Jenny.
