Research Ideas From a Mexican Reader
A reader called HDT writes to say:
I live in Mexico and have often wondered why more American economists and students of economics don’t often venture down here because the country offers what seems, to me at least, a treasure trove of economic oddities that should fascinate anyone interested in how markets work.
* As Mexico is heading toward what’s likely to be the second most important election in its history, the subject of vote-buying is of particular interest if for no other reason than that it’s practiced fairly openly, especially in rural areas. I know that during the last elections, here in Yucatan, votes were being bought, in cash, for around $80. (Pigs and cows were also exchanged for votes, but I wasn’t ever able to find out what the “going rate” was for those particular transactions.) There are, of course, people employed by the major political parties who specialize in determining what votes are worth throughout the country. I imagine they’re easier to find, and talk to, than you might expect.
* There’s also the rather intriguing issue of how Mexican real estate agents determine a reasonable price for any given property they’re hoping to sell. The problem is that it’s customary to decrease the tax burden on the sale of a home by getting the buyer to lie about how much he or paid. In other words, the sales prices stated in government records are almost never accurate. Everyone knows this. And yet, properties regularly change hands and real estate agents do manage to make a living. But how?
Any takers?
“Football Freakonomics”: How Advantageous Is Home-Field Advantage? And Why?
The following is a cross-post from NFL.com, where we’ve recently launched a Football Freakonomics Project.
Do home teams really have an advantage?
Absolutely. In their book Scorecasting, Toby Moscowitz and Jon Wertheim helpfully compile the percentage of home games won by teams in all the major sports. Some data sets go back further than others (MLB figures are since 1903; NFL figures are “only” from 1966, and MLS since 2002), but they are all large enough to be conclusive:
| League | Home Games Won |
| MLB | 53.9% |
| NHL | 55.7% |
| NFL | 57.3% |
| NBA | 60.5% |
| MLS | 69.1% |
So it’s hard to argue against the home-field advantage. In fact my Freakonomics co-author Steve Levitt once wrote an academic paper about the wisdom of betting (shh!) on home underdogs (more here).
But why does that advantage exist? There are a lot of theories to consider, including: “sleeping in your own bed” and “eating home cooking”, better familiarity with the home field/court, and crowd support. Read More »
A Twilight Opening Night Payoff Matrix
A student was interested in seeing the new Twilight movie, Breaking Dawn Part 1. And her roommate, a “Twi-Hard,” even had an extra ticket for the opening, midnight showing. The student likes seeing the vampires and werewolves occasionally, but cannot stand the continuing screams of the mostly pre-pubescent audience. She views her situation as a game with the following payoff bi-matrix: Read More »
Daron Acemoglu on Inequality
If you’re even a little bit interested in income inequality and how it matters, this Browser interview with MIT economist Daron Acemoglu is a must-read. Acemoglu explains how economists generally think about inequality:
Read More »The default position of economists is that inequality reflects the unequal human capital or productive capabilities of different workers. If you start with that premise – that what people earn is commensurate with their contribution to their employer, and also perhaps to society – then greater inequality tells you something about how people’s productivities have evolved over time. This is by no means what every economist believes, but it’s a common view. Economists have cut their teeth on inequality by looking at things like the increase in the college premium over the last 30 years in the U.S. and other economies, as well as the increase in the gap between relatively high earners – the 90th percentile of income distribution – versus the bottom 10th percentile. We’ve seen a big increase in inequality, measured in various ways, and this reflects the fact that the top people, the more educated, high earners have become more skilled. Technology has favored them, globalization has favored them, and inequality has increased for that reason.
