Abstract

This paper examines how pay-as-you-go (PAYG) pension reform from a defined-benefit scheme to a defined-contribution scheme affects economic growth in an overlapping generations model with endogenous growth. We show that in economies in which the old-age dependency ratio is relatively high and the size of pension benefits under a defined-benefit scheme is relatively large, PAYG pension reform from a defined-benefit scheme to a defined-contribution scheme mitigates the negative growth effect of population aging caused by a decline in the population growth rate or an increase in life expectancy.
