Human capital accumulation, fertility and economic development

摘要

We examine the development paths of an economy by incorporating the trade-off between the quality and quantity of children and the substitutability between the educational effect within the family and the education paid for by the parent. There is a threshold wage rate, above which individuals begin to invest in the human capital of their children, while reducing the number of children. At this point, the economy shifts from an exogenous growth phase to an endogenous growth phase. It is also shown that the aggregate saving rate is positively correlated with the youth dependency ratio in the development process.
