Population ageing and endogenous economic growth

Abstract

This article investigates the consequences of population ageing for longrun economic growth perspectives. We introduce population ageing into a generalized model of endogenous technological change incorporating the model of Romer (1990) and Jones (1995) as special cases. We find that increases in longevity have positive effects on steady state per capita output growth in endogenous as well as in semiendogenous growth models. In the latter case, the positive dependence can also be shown for the equilibrium growth rate during transition to the steady state.population ageing, endogenous technological change, long-run economic growth.
