CAPITAL‐ AND LABOR‐SAVING TECHNICAL CHANGE IN AN AGING ECONOMY
研究了人口老龄化是否影响经济增长,发现资本节约型技术变革的存在使得稳态增长率与年龄结构无关,长寿和生育率下降长期不影响增长。
Does population aging and the associated increase in the old‐age dependency ratio affect economic growth? The answer is given in a novel analytical framework that allows for population aging to affect endogenous capital‐ and labor‐saving technical change. In a steady state capital‐saving technical progress vanishes, and the economy's growth rate of per‐capita variables reflects only labor‐saving technical change. The mere possibility of capital‐saving technical change is shown to imply that the economy's steady‐state growth rate becomes independent of its age structure: Neither a higher life expectancy nor a decline in fertility affects economic growth in the long run.
