There is more research to come.
More educated people think more like economists. It's one of the big findings in my piece in the 2001 Journal of Law and Economics. And that's controlling for income, income growth, job security, gender, ideology, and party. It's a big effect, too: Every step up a 7-point educational scale matters about 9.3% as much as an economics Ph.D.
Those of us who hang around universities (well, other than GMU) find this hard to believe. "All the Ph.D.s I know are socialists!" This is a classic case of selection bias. Left-wingers with lots of education hang around universities; the rest get out while the getting is good.
DOES EDUCATION PRODUCE SOCIALISTS? Bryan at Econ Log is not so sure.
