Education and economic dynamism

Does a good educational system make for economic dynamism?

Check out the raw data on the American states for yourself. A more detailed look at the question would have to adjust for other relevant factors, but the sheer “eyeball effect” suggests a very weak link between education and economic dynamism, at least at the state level.

I am well aware of the macroeconomic growth literature that finds education to be a key driver of growth, see this article by Robert Barro.

How can we reconcile these two results? First, maybe education is critically important at lower levels of economic development, but not at higher levels. Second, the data on the states may not have enough ceteris paribus to be trustworthy. Third, the macro growth literature is weak on showing causal connections. I wonder: if we took out “education” and put “hours spent watching TV” into the cross-country regressions, what would the results look like?
