摘要：Increasing human capital investments in children is considered to be among the most effective ways of alleviating poverty and encouraging growth in developing countries. One possibly important channel through which such investments may have such impacts is through increasing cognitive achievement of children. There is a limited literature based on nonexperimental socioeconomic data that suggests that improved cognitive achievement has payoffs in terms of greater wages and perhaps productivities in labor markets in developing countries. These studies tend to find more substantial effects of cognitive skills than of schooling attainment if both are included, though of course schooling attainment may be affecting wages in part through cognitive achievement.
