Does Population Ageing Promote Faster Economic Growth?
Can divergent demographic trends account for differences in per capita output across countries? We address this question by offering evidence that the process of population ageing is positively and significantly related to cross-country economic performance. We define and estimate the effect of demographic change in two ways. First, a growing cohort of working age persons (15-64) as a share of the total population is found to have a large positive effect on GDP per capita . Second, an increase in the number of prime age persons (35-54) relative to the younger working age population (15-34) is found to have a positive but curvilinear effect with respect to per capita GDP. We find that changes in per capita GDP peak when the ratio of the prime-to-younger age population reaches an optimum of prime age workers for every younger aged worker. Beyond or below this optimal ratio, per capita output is lowered. Copyright 2008 The Authors. Journal compilation 2008 International Association for Research in Income and Wealth Published.
