This is a transcript of the Freakonomics Radio podcast “Baby, You Can Program My Car.” Kai RYSSDAL: Time now for a little Freakonomics Radio. It’s that moment every couple of weeks we talk to Stephen Dubner, the co-author of the books and blog of the same. The hidden side of everything is what he does. Hey […] Read More »
In our podcast “Waiter, There’s a Physicist in My Soup!,” we talked to Pablos Holman at Intellectual Ventures about food printers (we’ve also blogged about organ printers and meat printers). Now NASA is funding an Austin, Tex., company that is working on a pizza printer. From CNET:

Systems and Materials Research recently received a $125,000 grant from NASA to make a pizza. OK, it’s a little more complicated than that. Contractor already created a proof-of-concept printer that can print chocolate onto a cookie. His next goal is to print out dough and cook it while printing out sauce and toppings.
In the L.A. Times, Elizabeth Dunn and Michael Norton highlight some of the more interesting recent findings in the field of happiness research. Two surprising examples from the article:
1. “A study of women in the United States found that homeowners were no happier than renters, on average. And even if you’re currently living in a cramped basement suite, you may find that moving to a nicer home has surprisingly little impact on your overall happiness. Researchers followed thousands of people in Germany who moved to a new home because there was something they didn’t like about their old home. In the five years after relocating, the residents reported a significant increase in satisfaction with their housing, but their overall satisfaction with their lives didn’t budge.”
2. “[D]ozens of studies show that people get more happiness from buying experiences than from buying material things. Experiential purchases — such as trips, concerts and special meals — are more deeply connected to our sense of self, making us who we are. And while it’s anyone’s guess where the American housing market is headed, the value of experiences tends to grow over time, becoming rosier in the rearview mirror of memory.”
Writing at Slate, Ray Fisman reviews the latest research on the efficacy of charter schools. The study focuses on students at six Boston schools that had previously demonstrated an ability to improve students’ test scores on the Massachusetts Comprehensive Assessment System. This time, however, the researchers wanted to evaluate whether the schools really improved student outcomes or just mastered the art of “teaching to the test.” Here’s the breakdown:

The study examines the college readiness of Boston public school students who applied to attend the six charter schools between 2002 and 2008, with projected graduation dates of 2006–2013. In just about every dimension that affects post-secondary education, students who got high lottery numbers (and hence were much more likely to enroll in a charter school) outperformed those assigned lower lottery numbers. Getting into a charter school doubled the likelihood of enrolling in Advanced Placement classes (the effects are much bigger for math and science than for English) and also doubled the chances that a student will score high enough on standardized tests to be eligible for state-financed college scholarships. While charter school students aren’t more likely to take the SAT, the ones who do perform better, mainly due to higher math scores.

Aon just released its 2013 Terrorism and Political Violence Risk Map. Interestingly, reports Business Insider, the risk levels in summer vacation favorites France and Spain are “actually equivalent to China and Russia, presumably on the basis of the former countries’ recent, heated demonstrations protesting austerity.”
Denmark, Finland, Japan, Australia, Iceland, Uruguay and Botswana, meanwhile, are all pretty safe bets.

A new NBER working paper (PDF; abstract) by economists Scott E. Carrell and Bruce Sacerdote finds that educational incentives, even those that are offered to students late in their senior year of high school, can impact college outcomes. Here’s the abstract:
We present evidence from an ongoing field experiment in college coaching/ mentoring. The experiment is designed to ask whether mentoring plus cash incentives provided to high school students late in their senior year have meaningful impacts on college going and persistence. For women, we find large impacts on the decision to enroll in college and to remain in college. Intention to treat estimates are an increase in 15 percentage points in the college going rate (against a base rate of 50 percent) while treatment on the treated estimates are 30 percentage points. Offering cash bonuses alone without mentoring has no effect. There are no effects for men in the sample. The absence of effects for men is not explained by an interaction of the program with academic ability, work habits, or family and guidance support for college applications. However, differential returns to college and/or occupational choice may explain some of the differences in treatment effects for men and women.
