Happiness Trends Lead to Some Strange Places

Interdisciplinary research can take you to some unexpected places. You may have heard about a paper that Betsey Stevenson and I wrote a while back, documenting that the average level of happiness among women has trended downward relative to that of men. It’s an interesting fact, and we aren’t quite sure whether it tells us about the reliability of happiness data, the women’s movement, or other changes in men’s and women’s lives.



A Scholar to Keep Your Eye On

Amadu Jacky Kaba is a Liberian-born striver who first came to Seton Hall University as a basketball player and, several degrees later, has returned as an assistant professor of sociology and anthropology. Like our friend Roland Fryer, Kaba is a black scholar who studies a lot of racial issues with a perspective and a latitude that is unavailable to white scholars.



A Gut Yontif for L.A. Drivers

This was no fluke; there’s a big improvement in the Westside traffic situation every year on the Jewish high holidays. To many, this seems mysterious. True, West L.A. and the southern San Fernando Valley have large Jewish populations, but not that large.



Don't Hate the Tweet

Tyler Cowen shuns the doubters and blogs about what Tweeting means to him: instant feedback on lectures, an essential tool for researching blog posts, and an efficient alternative to a Google search.



Can "Charter Cities" Change the World? A Q&A With Paul Romer

Weak institutions and bad rules are some of the most significant obstacles to economic growth in developing countries. Paul Romer, an economist known for his work on economic growth, has a plan to change that and recently resigned his tenured teaching position at Stanford to devote his full energies to the challenge.



Wanted: Economic Advice from Students (Reward!)

The institute is offering cash prizes to the high-school and post-secondary students who provide the best answer (in video format) to the question “What is the appropriate role of government in the economy?”



Shaq and the Case of the Missing Bribes

The extortion concern might explain a lot of our reluctance to offer bribes. But there are circumstances where a one-off bribe can work wonders. When my kids were little, I remember bribing a college student on an Amtrak train to move to another open seat so that my family could sit together.



Is the Senior Slam Smart?

Denny’s breakfast menu in Provo, Utah, offers something that combines demand-based and cost-based price discrimination, but it’s neither.
The “French toast slam” is two pieces of toast and two eggs, two strips of bacon and two sausages for $6.99. The “senior French toast slam” is one piece of toast and one egg, and two strips of bacon or two sausages for $5.49, and you must be at least 55 years old to buy this.



The Priesthood

Kahneman, who has described economics as a strict priesthood, says, “Yes, I have spoken of a church, but it is not a church where you get burned at the stake for being a heretic, because otherwise a lot of people wouldn’t be around!”



Don't Read This Post

Quick, how many of you can tell me:
1. Your cars’ fuel economy in miles per gallon or, even better, gallons per mile.
2. How much you drove in the last year.
3. The cost to fill your tank.
4. Your monthly and annual fuel expenditures.
5. How your cars’ fuel economy sits in relation to other cars in their classes.
6. What your fuel savings in gallons and dollars would be if you switched to a hybrid or other highly economical vehicle.



Etc. in the Graveyard

From my office window, I have a glorious view of the Grove Street Cemetery, where Yale students often go to read. By far, my favorite spot in this vast city of monuments is near the end of Cedar Avenue, past the graves of Eli Whitney and Noah Webster. There, just beyond the intersection with Myrtle Path, you can find the extraordinary headstones of two Yale chemists.



Can Mobile Phones Change the World?

The Economist has a special section this week on mobile phone technology in emerging markets. The section includes articles on trends in mobile phone ownership, the role mobile phones are playing in economic development, and new uses for the technology.



Goodie-Free Bags

I especially like that last paragraph; not only is Clinton doing something different, but there is an economic twist to it. By letting people allocate their points, it is revealing attendees’ preferences as well.



The U.S. With Less God

A Trinity College survey predicts a quarter of Americans will identify as nonreligious in 20 years (as opposed to the 15 percent who do so now). Dan Gilgoff, in his U.S. News column, predicts what that might to do American politics.



We Made a Huge Mistake

Dubner and I both made a huge mistake: we got married before Freakonomics came out.





Wouldn't It Be Nice to Really Pay What You Wish?

So plainly there are limits to the viability of PWYW. But one factor that PWYW pricing calls into play is human conscience: if set up properly, PWYW can make it hard for all but the most callous customer to rip you off.




How To Measure Rosh Hashanah Services

My wife and I were speculating on how long last Friday’s Rosh Hashanah service would last. We both figured on two hours, but my wife said, “Services always last longer than you expect.”



Are We In for a Dull Fall?

Biologists from the Proctor Maple Research Center at the University of Vermont plan to study how climate change might affect this year’s “foliage viewing season,” whether it is longer, shorter, or more muted.



Freakonomics Quiz: Anointing the King

So in my continual (and seemingly fruitless) attempt to stump the readers of this blog, I offer what may be the most difficult Freakonomics quiz ever:
What magazine was the first to use the phrase “King of Farts” in reference to my father’s research?



The Prom Effect?

Researchers have long puzzled over the relatively poor health and education outcomes for babies born in the winter months. Past explanations have focused on school attendance laws, vitamin D exposure, and other environmental factors, but economists Kasey Buckles and Daniel Hungerman have found an overlooked explanation.



The Undercover Economist Answers Your Questions

I would recommend introducing your wife to the theory of real option valuation. Point out that the option to marry her was likely to remain open for many years after you originally met. By exercising the option so early, you showed your bride that the net present value of your relationship was large and positive and your uncertainty about the decision was very low.



Smallpox as Art

Installation artist Luke Jerram creates glass sculptures of diseases to “contemplate the global impact of each disease and to consider how the artificial coloring of scientific imagery affects our understanding of phenomena.”



The Plague of Medical Research

There is nothing conclusive in this report, but it is nevertheless sad and remarkable: Malcolm Casadaban, a University of Chicago medical researcher working on a better vaccine for the plague (Yersinia pestis), has died at the age of 60 and was found to have Yersinia pestis in his bloodstream.




Why My Students Don't Get Rebates

Ian Ayres recently posted about his returning to his students the royalties on his book that he assigned to them.
This has caused me trouble: one of my students read it and asked why I don’t do that as well for my little book, Economics Is Everywhere. I have done this before, when I assigned my labor economics text to a class of 35 students, but not in her class.



The Debt Clock

In the spirit of its Big Mac Index, The Economist rolled out its Global Debt Clock, which features a running global-public-debt tally.



Lemons From Lemonade

Although hybrids and electric vehicles can help automakers meet these targets, enough efficiency can be reaped with internal combustion autos. This can come through improvements to things like tires, engines (e.g. smaller ones with turbocharging), air conditioning, transmissions, and vehicle weight. The administration estimates that this will cost $1,100 per vehicle but that the improvements will pay for themselves with $3,000 in fuel savings over the life of the car.
