Ricardo Hausmann has an excellent and provocative column, here is part of it:
In the 50 years from 1960 to 2010, the global labor force’s average time in school essentially tripled, from 2.8 years to 8.3 years. This means that the average worker in a median country went from less than half a primary education to more than half a high school education.
How much richer should these countries have expected to become? In 1965, France had a labor force that averaged less than five years of schooling and a per capita income of $14,000 (at 2005 prices). In 2010, countries with a similar level of education had a per capita income of less than $1,000.
In 1960, countries with an education level of 8.3 years of schooling were 5.5 times richer than those with 2.8 year of schooling. By contrast, countries that had increased their education from 2.8 years of schooling in 1960 to 8.3 years of schooling in 2010 were only 167% richer. Moreover, much of this increase cannot possibly be attributed to education, as workers in 2010 had the advantage of technologies that were 50 years more advanced than those in 1960. Clearly, something other than education is needed to generate prosperity.As is often the case, the experience of individual countries is more revealing than the averages. China started with less education than Tunisia, Mexico, Kenya, or Iran in 1960, and had made less progress than them by 2010. And yet, in terms of economic growth, China blew all of them out of the water. The same can be said of Thailand and Indonesia vis-à-vis the Philippines, Cameroon, Ghana, or Panama. Again, the fast growers must be doing something in addition to providing education.
The piece is interesting throughout.
