Health and Schooling Investments in Africa
比较发现非洲的健康和教育水平落后于其他地区，但微观估计显示私人回报率较高，说明人力资本投资将影响非洲未来经济增长和分配。
Intercountry comparisons show Africa's health and education falls short of other regions, controlling for income, women's educations, and urbanization, but growth regressions do not clarify whether this low human capital caused slow growth. Microeconometric estimates of wage returns to schooling and health indicate relatively attractive private returns in several sub-Saharan countries, although data are severely limited. Biases due to household heterogeneity and selection into the sample of wage earners do not appear to alter these assessments that the quantity and quality of human capital investments will affect future economic growth in Africa and its more equitable distribution.
