Thanks a lot for the link, it is a very interesting study (reading that ATM), however they only consider the increase in year of education - or, as written in the comments on the blog "There is proof that more people received more years of schooling, but there is no proof that more people became more educated" It could be another Leontief-like paradox, ie discarding the education efficiency. I would be curious to know if such results hold when only STEM education is included (no humanities), and if there appear difference between pre-university and university education (I would expect raising the population literacy to have less effects - ie starting from a lower education might require more investment in education) once corrected by emigration (brain drain- remittances will help, but we're looking at something else)
