Population aging and endogenous economic growth
研究了人口老龄化对长期经济增长的影响，发现寿命延长促进人均产出增长，而生育率下降则起抑制作用；在内生增长框架下，老龄化总体促进长期增长。
We investigate the consequences of population aging for long-run economic growth perspectives. Our framework incorporates endogenous growth models and semi-endogenous growth models as special cases. We show that (1) increases in longevity have a positive impact on per capita output growth, (2) decreases in fertility have a negative impact on per capita output growth, (3) the positive longevity effect dominates the negative fertility effect in case of the endogenous growth framework, and (4) population aging fosters long-run growth in the endogenous growth framework, while its effect depends on the relative change between fertility and mortality in the semi-endogenous growth framework.
