Abstract

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. The short-run analysis reveals that population aging induces more labor- and less capital-saving technical change as it increases the relative scarcity of labor with respect to capital. Due to external contemporaneous knowledge spill-overs across innovating firms induced technical change has a first-order effect on current aggregate income. In the long-run capitalsaving technical progress vanishes, and the economy’s growth rate reflects only labor-saving technical change. However, 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.
