Abstract
This paper examines how pay-as-you-go (PAYG) pension reform from a defined-benefit scheme to a defined-contribution scheme affects fiscal sustainability and economic growth in an overlapping generations model with endogenous growth. We show that in economies in which the old-age dependency ratio is high and the size of pension benefits under a defined-benefit scheme is large, such a pension reform mitigates the negative effect of population aging on fiscal sustainability and economic growth. However, we also show that this type of pension reform entails an intergenerational conflict of interest between current and future generations. Population aging might exacerbate the extent of this conflict.
