Does Early Education Reduce the Achievement Gap?

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List also appeared in our recent podcast “How to Raise Money Without Killing a Kitten.”

The past 60 years in the U.S. has seen dramatic policy changes to the public-education system. The ‘50s, ‘60s, and ‘70s saw desegregation and affirmative action, and since the ‘80s there have been efforts to increase school funding, the introduction of voucher systems, and the creation of countless charter schools. In between we’ve seen efforts to reduce class sizes, introduce technology into classrooms, improve teacher credentialing, and a massive attempt to leave No Child Left Behind. 

What do we have to show for all this? That’s hard to say. Even though many programs have a high price tag, they were never implemented with an eye towards assessment. The data we do have shows that not much has changed over the past 30 years. The figure attached shows how the racial achievement gap in test scores has persisted for white and black Americans since the late 1970s. 

If you don’t like the breakdown by race, then consider that the high school dropout rate among high-income families in 1972 was 2% and in 2008 it was still at 2%. For low-income families, though? In 1972 it was 14% and in 2008 it was still at 9%. This sort of trend (or lack thereof) is manifested in dozens of measures of academic achievement, all of which suggest that the past 60 years of educational reform has very little to show for itself.


What Makes People Do What They Do?

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List appeared in our recent podcast “How to Raise Money Without Killing a Kitten.”

Money is important. For a long time, economists thought that it was the only thing that mattered. And, in fact, if you want people to do what you want, money can be incredibly useful. Out to entice the best workers? Pay more. Want to sell a product? Discount it, a lot. Want to discourage a bad behavior? Impose a monetary fine.

It seemed a little silly to us though (as well as to other behavioral economists doing work back in the 1990s) to think that money was the only thing that mattered. So we set out to learn exactly when and how monetary incentives work. Along the way, we discovered some environments where incentives don’t work at all. 


How to End (Price) Discrimination

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List appeared in our recent podcast “How to Raise Money Without Killing a Kitten.”

The passage of the Americans with Disabilities Act was a landmark civil rights bill. It afforded the disabled protections against discrimination that were similar to earlier landmark civil rights bills. In particular, the bill targeted two types of discrimination. One type was the discrimination against the disabled motivated by hatred or disgust. For example, one provision targeted employers that denied employment opportunities to those that truly qualified. Other parts of the bill focused on ensuring a level playing field for the disabled, like one requirement for businesses to make readily achievable retrofits to their businesses to afford the disabled access.

When economists think about the causes of discrimination, they tend to lump them into these two categories. The first is called animus discrimination, which is the type of discrimination we tend to associate with the treatment of African-Americans in the early 20th century. The second is called statistical discrimination, which is discrimination motivated by statistical trends associated with groups. For example, women tend to pay less for auto insurance because they are safer drivers. 


How Can We Save Ourselves From Ourselves?

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List also appeared in our recent podcast “How to Raise Money Without Killing a Kitten.”

It’s a late-September afternoon in 2009 and the students of Fenger High School on Chicago’s South Side are crossing a vacant concrete lot. Some live in the Altgeld Greens housing project. Others live in a part of Chicago’s rough Roseland neighborhood (also called “The Ville”).  Some of the students from these areas have developed fierce antipathies toward each other, though the groups are more like cliques than gangs.

As the teenagers cross the lot, a fight breaks out. Someone pulls out a cell phone and starts recording a video of 15 to 20 kids fighting. Around a minute into the video, someone discovers a couple of two-by-fours lying in the empty lot. Eugene Riley, sporting a red motorcycle jacket, takes one of the big pieces of wood from a pal and swings it like a baseball bat into the back of 16-year-old honor student Derrion Albert’s head.


Charity and the Beauty Effect

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new  book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List appeared in our recent podcast “How to Raise Money Without Killing a Kitten“; the post below offers a fuller description of an experiment discussed in that podcast.

On a chilly Saturday afternoon in December, 2005, Jeanne, a bright, energetic junior at East Carolina University (ECU), trotted up the walk of a suburban home in Pitt County, N.C. Jeanne wore a shirt emblazoned with the name “ECU Natural Hazards Mitigation Research Center.” She also wore a badge with her photograph, name, and solicitation permit number on it. She knocked, and a middle-aged man opened the door. 

“Yes?” he said, eyeing her. 

“Hi,” she said, smiling brightly. “My name is Jeanne. I’m an ECU student visiting Pitt County households today on behalf of the newly formed ECU Natural Hazards Mitigation Research Center. Would you like to make a contribution today?” It’s probably safe to say that the last thing the middle-aged man had on his mind was the possibility of Jeanne being a double agent. Yes, she was really trying to raise money for the center. But she was also part of a bigger experiment involving dozens of college students knocking on the doors of 5,000 households in Pitt County. 


What Can a Ball and a Bucket Teach Us About Why Women Earn Less Than Men?

John List and Uri Gneezy have appeared on our blog many times. Now they have written a book, The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. (The title, by the way, was crowdsourced on this blog). Below is the first in a series of guest posts adapted from the book; Gneezy spoke about this research in our podcast “Women Are Not Men.”

What can a Ball and Bucket Teach Us About Why Women Earn Less than Men?
By Uri Gneezy and John List

The sign on the road leading to the city of Shilong in the Khasi hills of northeast India had a puzzling message: “Equitable distribution of self-acquired property rights.” Later we’d find out that the sign was part of a nascent men’s movement, as the men in the Khasi society were not allowed to own property. We’d traveled across the world in search of such a parallel universe—one where men felt like “breeding bulls and babysitters”—because evidence in the U.S. was starting to point to a massive gap in preferences towards competition between the genders and we wanted to understand the reason why.

Our plan was to take a simple game to a matrilineal society (the Khasi) and patrilineal society (the Masai in Tanzania) and give participants just one choice: Earn a small certain payment for their performance in the game or earn a much bigger payment for their performance, but only if they also bested a randomly chosen competitor. The game we settled on? Tossing tennis balls into a bucket 3 meters away.  The experiment was conducted with Kenneth Leonard as a coauthor.


Thanks to Freakonomics Blog Readers (Sort of), the Gneezy and List Book Finally Has a Title

A while back we held a contest for the new popular economics book written by Uri Gneezy and John List. The authors and their publishers picked some of their favorite title suggestions and then we ran a beauty contest to determine which title was most popular among blog readers. The deal was that the person who proposed the winning title would get $1,000. Another $1,000 was to be split between randomly selected beauty contest participants.

Before I tell you which title won, let me tell you about the naming of Freakonomics. We had such an impossibly hard time coming up with a good name until my sister Linda came up with “Freakonomics.” To make a long story short, the publishers hated that name for a long time, but finally gave in. The rest is history. Of course we were all just guessing — it would have been nice to have data, the way Uri and John did.

So what do the data say? The winner of the beauty contest, with 33 percent of the votes, was The Carrot that Moved A Mountain: How the Right Incentives Shape the Economics of Everyday Life. Congratulations to Ivy Tantuco who proposed that title and collected the $1,000 prize.(Congratulations also to Jenna Dargie and Melinda Reiss, who were the randomly chosen beauty contest winners and pocketed $500 each.)


Another $1,000 at Stake in the Gneezy-List Book Title Experiment

A couple weeks ago, Uri Gneezy and John List asked our blog readers to come up with titles for their new book.  And our readers did not disappoint!  There were over 400 suggestions, many of them brilliant.

The authors and their editors have now narrowed it down to five choices, and they once again are asking for your help in deciding on the final title.  There is no better way to solicit that input than — you guessed it — a field experiment.  To get you interested, they are putting up another $1,000 in prizes to participants.

The rules are simple: You go here and answer  two simple questions.

First, you will be asked to choose which of the five titles you think will be the most popular among all the respondents.  They don’t want to know your favorite title, they want to know the title you think other people will like best.


Here’s Your Chance to Name a (Soon-to-Be) Best-Selling Book and Win $1,000

 My close friend, colleague, and frequent co-author John List has written a popular (non-academic) book with another economist, Uri Gneezy.  John and Uri are pioneers in the area of “field experiments” which bring the power of randomized experiments into real-world settings.   In my opinion, field experiments are the future of empirical economics.  We’ve written at length in our books and on our blog about the amazing work these two have been doing. I’ve had the chance to read John and Uri’s book, and I loved it.

The thing they can’t figure out, however, is what to call the book!  If only my sister Linda – the greatest namer of things the world has ever known — were still around, she would figure out a great title for sure.  In her absence, they’ve asked if I could mobilize the collective genius of you, the Freakonomics blog readers.

Okay, so here is the deal.  Below, I’ve provided some information on the book and links to some materials that might prove useful to you in coming up with a name.  You have two days to generate great titles for the book, which you can submit as comments on this blog post.


The FREAKest Links: Potter Deathwatch Edition

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. Gelf magazine has an interview with the economist Uri Gneezy, who . . .
