Eric Hanushek, Senior Fellow at the Hoover Institution, talks about his research on the impact of educational quality on economic growth. Past efforts to increase the economic growth rate of poor countries have focused on years of schooling, neglecting the quality and true education that needs to take place. Hanushek presents dramatic findings about the decisive nature of cognitive ability and knowledge in driving economic growth. Join us as Hanushek talks with EconTalk host Russ Roberts about his findings and the implications for public policy around the world and in the United States.
