Garett Jones: A Very Intelligent Economist on Economics and Intelligence
GUEST BLOGGER | Bryan Caplan
Thirteen years after Herrnstein and Murrayâ€™s The Bell Curve outraged the country, itâ€™s hard to find a serious social scientist who denies that intelligence is a Very Big Deal. But it still takes courage to push the envelope. Thatâ€™s just one of the reasons why Iâ€™m thrilled that Garett Jones, a leading expert on economics and IQ, will be joining the faculty of George Mason University, where I work, this fall.
So whatâ€™s Garett been up to? For starters, heâ€™s done the most careful statistical study (with co-author W. Joel Schneider) of the relationship between intelligence and economic growth. Published in the prestigious Journal of Economic Growth, the Jones-Schneider study find that â€?In growth regressions that include only robust control variables, IQ is statistically significant in 99.8% of these 1330 regressions, and the IQ coefficient is always positive. A strong relationship persists even when OECD countries are excluded from the sample. A 1 point increase in a nationâ€™s average IQ is associated with a persistent 0.11% annual increase in GDP per capita.â€?
Garettâ€™s got another neat paper on intelligence and cooperation in Prisonersâ€™ Dilemma experiments. By combining data from many previous experiments, and looking up the average SAT scores of the schools where the experiments were conducted, Garett answers a big question on the cheap. Result: â€?A meta-study of repeated prisonerâ€™s dilemma experiments run at numerous universities suggests that students cooperate 5% more often for every 100 point increase in the schoolâ€™s average SAT score.â€?
But my personal favorite is Garettâ€™s job market paper (also co-authored with Schneider), â€?IQ in the Production Function: Evidence from Immigrant Earnings.â€? A common objection to international IQ comparisons is that the tests are not cross-culturally valid. This paper shows that the average IQ of immigrantsâ€™ country of origin predicts a lot about immigrantsâ€™ earnings in the U.S. In short, despite obvious shortcomings of international IQ tests, they still predict real-world outcomes right here in the U.S.
Now I should add that Garett Jones works in several other areas of economics, too. But Iâ€™m confident that his work on economics and intelligence will bring him the most attention and the most controversy. As I see it, that makes him a perfect fit for GMU.
By the way, George Mason U. itself is an interesting story. It was a nondescript public college in Washington D.C.'s Virginia suburbs. A couple of decades ago, it came up with the idea of hiring conservative and libertarian academics—nearby Washington provided demand for them and they were cheap on the market. Conservative foundations subsidize George Mason, and professors are encouraged to be public intellectuals. Thus, the large presence of George Mason economists in the blogosphere and their constantly blogrolling for each other. (The irony of course is that these libertarians are employed by the state of Virginia.) This strategy has raised GMU's public profile considerably, although it doesn't appear to have done all that much yet to attract a stronger student body. Still, in the sleepy world of academia where the reputations of institutions change only glacially, it shows that colleges can alter their fate if they are willing to try something new.
