    Abstract: We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large-scale assessment in 14 countries that include individual-level information on student achievement and country-level measures of teacher subject knowledge and didactic skills in reading and math. Exploiting variation between subjects in a student fixed-effects model, we find that teacher subject knowledge has a large positive effect on student achievement, whereas the effect of didactic skills is comparatively small and not statistically signifiant at conventional levels. Together, the two dimensions of teacher quality account for 36 percent of the variation in average student achievement across countries.

  2. By: Jaan Masso; Amaresh K Tiwari
    Abstract: We study the productivity implications of R&D, capital accumulation, and innovation output for entrants and incumbents in Estonia. First, in contrast to developed economies, a small percentage of firm engage in formal R&D, but a much larger percentage innovate. Second, while we find no difference in the R&D elasticity of productivity for the entrants and incumbents, the impact of innovation output - many of which are a result of 'doing, using and interacting' (DUI) mode of innovation - is found to be higher for the entrants. Entrants who innovate are 21% to 30% more productive than entrants who do not; the corresponding figures for the incumbents are 10% to 13%. Third, despite the adverse sectoral composition typical of catching-up economies, Estonian incumbents, who are the primary carriers of 'scientific and technologically-based innovative' (STI) activities, are comparable to their counterparts in developed economies in translating STI activities into productivity gains. Fourth, while embodied technological change through capital accumulation is found to be more effective in generating productivity growth than R&D, the effectiveness is higher for firms engaging in R&D. Finally, our results suggest that certain policy recommendations for spurring productivity growth in technologically advanced economies may not be applicable for catching-up economies.
