Abstract:Using the two-step system general method of moments panel data analysis the authors first investigate the effects of external financial flows on total factor productivity and technological gain, and then use the beta catch-up and sigma convergence to compare dispersions in output per worker, total factor productivity and technological gain in sub-Saharan Africa (SSA) for the years 1980-2010. The comparative evidence is articulated with income levels, years of schooling, and health factors. The authors find; first, a positive association between foreign direct investment, trade openness, foreign aid, remittances and total factor productivity. However, when foreign direct investment is interacted with schooling, its direct effect becomes negative on total factor productivity. Second, beta catch-up is between 19.22 percent and 19.70 percent per annum with corresponding time to full catch-up of 25.38 years and 26.01 years respectively. Third, they find sigma-convergence among low-income nations and upper-middle income nations separately, but not for the entire sample together. Fourth, schooling in SSA is not yet a significant source of technology, but it can make external financial inflows more effective. Policies to induce external financial flows are not enough for development if absorptive capacity is low. App., bibliogr., sum. [Journal abstract]
