Game Strategy in Biblical Times

Genesis 20:1-18 tells of Abraham visiting Avimelech and offering him Sarah (who, so Abraham tells Avimelech, is his sister, when she is also his wife).



Announcing SuperFreakonomics: The Illustrated Edition

We are pleased to announce the publication of a new book: SuperFreakonomics: The Illustrated Edition. It’s a large-format book built around the original text of SuperFreakonomics, with hundreds of new visual elements and quite a bit of new text as well.



Detecting Political Momentum Is Harder Than You Think

Over at FiveThirtyEight.com, Nate Silver has a post attempting to debunk the idea that there is momentum in political campaigns. But I think he’s wrong. And his post provides a fun opportunity for a simple statistics lesson on the difficulty of discovering momentum.



Homer Simpson: A True Catholic?

This just in from the Vatican’s daily broadsheet: “Few people know it, and he does everything he can to hide it, but it is true: Homer J. Simpson is a Catholic.”



Pesticide Politics

Pesticides freak us out – and understandably so. The idea of otherwise healthy fruits and vegetables marred by residual poison unnerves us because, generally speaking, we’re clueless. We’re totally removed from the process of production. We don’t know what was sprayed, we can’t see the trace pesticides, we can’t measure them on our own, and, let’s face it, the vast majority of us don’t remotely understand how these agents work. The upshot is that we’re left to trust outside interpreters to assess the risk for us.




Churches Versus Synagogues: Voluntary Donations Versus Dues

Christian churches and Jewish synagogues rely on very different financing models, yet both “appear to raise about the same amount per member,” according to a survey conducted by the Jewish newspaper The Forward (article by Josh Nathan-Kazis). While synagogue members pay annual dues, churches rely primarily on voluntary donations from members.



How Does Your Kid's School Rank?

Katherine Mangu-Ward at Reason writes that interested parties can now find out how their school stacks up against other schools using the Education Nation Scorecard.



The Bigger the Group, the Less Likely Pareto Improvements?

All classes were canceled at the University of Texas one recent Tuesday because of a shooting at the main library. I already had a haircut appointment scheduled for 4 p.m. and suddenly had a lot of free time before then. I called the hairdresser and asked to come by at 2. She was free then. This gave me a preferable work schedule; and, as I had been her last appointment, she got off work early.



Matthew Kahn Answers Your Climatopolis Questions

Last week, we solicited your questions for Matthew Kahn, the author of Climatopolis: How Our Cities Will Thrive in the Hotter Future. His answers, covering everything from water scarcity to Moscow’s recent heat wave, are below. A big thanks to Matt – and to everyone who participated.



Slowing Down to Increase Profits?

In the face of economic pressures and customer complaints about coffee quality, Starbucks has revised its drink-making guidelines for baristas: “Starbucks baristas are being told to stop making multiple drinks at the same time and focus instead on no more than two drinks at a time-starting a second one while finishing the first,” reports The Wall Street Journal.



Our Love/Hate Relationship with Carrots and Sticks

“The honeymoon is over.” These are the words of Alberto Iturra, the leader of a team of psychologists who have instituted a series of prizes and punishments to change the behavior of the 33 miners trapped in Chile. When the miners do what the psychologists want, they are given treats like T.V. and music. But if miners refuse, say, to submit to daily interviews with psychologists, the psychologists will restrict the supply of cigarettes or wine.



For a First Date, Wear Red

A new study, summarized in the BPS Research Digest, finds that when it comes to the color red, humans aren’t that different from chimps: they both love red.



What's the Biggest Tax Mistake That Might Be Made This Year? A Freakonomics Quorum

Consider the ingredients: a frail economy, a toxic political environment, looming hard deadlines and massive uncertainty in the business community – the perfect circumstances under which to write some great federal tax policy!
But tax-code writing will be done – on the expiring Bush-era tax cuts, the estate tax, the Alternative Minimum Tax, capital-gains taxes and more.



Quotes Uncovered: Wisdom From Business Leaders

Continuing with my requests for famous quotations and sayings that might make it into the next edition of The Yale Book of Quotations, I’d like now to ask for memorable recent (or not-so-recent) words of wit or wisdom from business leaders.



Prepare for Landing: The Friendly Skies Competition Winner

There is a dark side to the popular Freakonomics contest: the allure of Freakonomics schwag can turn otherwise rational, law-abiding people into animals willing to violate any norm of civilized behavior. As a result, there has been skullduggery in our competition in which we asked for your best (or worst) air travel stories. More in a bit.
But first, a couple of entries that are too late for prize consideration but quite amusing nevertheless.




The Graying of the World

Foreign Policy takes a look at aging around the world in an article and a photoessay. The article analyzes a number of aging myths. For example, lower birthrates aren’t exclusive to rich countries.



Betsey Stevenson Answers Your Questions

We recently solicited your questions for Betsey Stevenson, a sometimes Freakonomics contributor and newly minted Chief Economist of the Department of Labor. Your questions were excellent and varied, and Betsey’s responses cover everything from persistent unemployment to parental leave. Thanks to Betsey and everyone who participated.




Should the Nobel Folks Be Sued for the Financial Crisis?

The recent financial crisis clearly had many contributing villains. But if you’re looking to sue someone to recover losses, Nassim Nicholas Taleb maintains, the choice is clear: the Swedish Central Bank, which awards the Nobel Prize in Economics,



What Is Going on With Marriage?

You’ve probably heard the latest marriage narrative: With the recession upon us, young lovers can’t afford to marry. As appealing as this story is, it has one problem: It’s not true.



Spicing Up the Awkward First Date Conversation

Dan Ariely brings behavioral economics to the awkward, boring first date conversation: “Basically, in an attempt to coordinate on the right dating strategy, we stick to universally shared interests like food or the weather.”



Getting Paid to Lose Weight

The results are in. I’m happy to report that my eBay auction ended with a winning bid of $282.85. Twenty-three bidders put in a total of 45 bids. The bidders were a mixture of seasoned eBay users (some with more than 150 eBay purchases) and newbie eBay users.



Social Security and Inflation

We “Greedy Geezers” will not be getting an increase in our monthly Social Security benefit payments in January, because the CPI is still below what it was in 2008.



The Theory of Interstellar Trade

I did not think that Paul Krugman was still writing academic papers. Nor have I seen any evidence in the last decade that he still has any sense of humor.
Consequently, I was surprised to see an article written by him entitled “The Theory of Interstellar Trade,” published recently in the journal Economic Inquiry.



Innovation Nation

If you want to live somewhere particularly innovative, consider Boston, Paris or Amsterdam.




Congratulations to Peter Diamond on Winning the Nobel Prize in Economics

The first time I met Peter Diamond, nearly 20 years ago, I was a prospective student visiting MIT. He was wearing sandals without socks as he taught a graduate class. I remember thinking that was odd. As I sit here in my office, I am wearing sandals without socks. Perhaps Peter Diamond influenced me in ways I never imagined.
I was delighted to see that Peter Diamond shared the Nobel Prize today with two other economists (Mortensen and Pissarides, who I don’t know personally but are very highly respected).



Euphemisms for China

We’ve all done it. You’ve been introduced to someone, but forget his or her name. And so you spend the rest of the conversation studiously avoiding needing to refer to your new friend by name. Well, as far as I can gather, the same thing happened on Wednesday to Treasury Secretary Tim Geithner. He gave a talk at Brookings that was all about China, but if you didn’t know better, you could be forgiven for thinking he had forgotten her name.
