The Age Structure of Human Capital and Economic Growth
研究发现，40-49岁人口的教育水平对经济增长的影响比其他年龄段大一个数量级，且这一效应与人口年龄结构的影响不同。
Abstract This paper shows that the age structure of human capital is a relevant characteristic to take into account when analysing the role of human capital in economic growth. The effect of an increase in the education of the population aged 40–49 years is found to be an order of magnitude larger than an increase in the education attained by any other age cohort. The results are unlikely to be driven by the age structure of the population, as we find that the effects on growth of the age structure of education and the age structure of population are distinct. The findings are robust across specifications and remain unchanged when we control for long‐delayed effects in human capital or for the experience of the workforce.
