Population age structure and secular stagnation: Evidence from long run data

The Journal of the Economics of Ageing, 2023, vol. 24, issue C
Abstract:
A large literature has reopened the secular stagnation hypothesis, first proposed near the end of the great depression as a warning for anemic growth resulting from long run trends in population aging. In this paper, I explore the relationship between population age structure and growth in: investment, consumption and output, in a long run panel of advanced economies. The evidence is largely consistent with proposed channels for secular stagnation. Investment growth, in its level and as a fraction of GDP, appears much stronger in young populations, while facing demographic headwinds in older economies. Consumption and output growth are positively associated with late career workers, with a negative relationship coming from both young and old dependents. Consistent with the recent secular stagnation literature, interest rate channels appear to have strong interactions with population age structures. I find that for investment and output growth, estimated impacts of age-structure are more pronounced in low interest rate environments, with high rates mitigating some of their effect.
