Cognitive skills, innovation and technology diffusion

George Messinis () and Abdullahi Ahmed

Economic Modelling, 2013, vol. 30, issue C, 565-578

Abstract: This article presents new international estimates of human capital for the period 1970–2003. The new latent index is used to re-examine the Benhabib and Spiegel (2005) model of technology diffusion in a horse-race with the competing indicators of Barro and Lee (2010) and Hanushek and Wößmann (2009). Analysis employs cross-section and panel econometrics, extends beyond the Cobb–Douglas technology, and deals with endogeneity bias. Robust evidence confirms the significance of cognitive skills as a driver of innovation and diffusion. Although there is substantial diversity, the new human capital index has declined in many countries in Africa and the OECD.
