Social Security and Intragenerational Redistribution of Lifetime Income in Japan
This paper investigates how social security redistributes lifetime income within the same generation in Japan, based on data from the Survey on the Redistribution of Income. The progressivity of Japan's public pension program appears to be much more limited on a lifetime basis than on an annual basis. Given an aging population, replacing the current pay-as-you-go system with a simple one that consists of a flat benefit and a wage-proportional premium, and has no maximum contribution, can be desirable in terms of both efficiency and intragenerational equity. The redistributive effects of income tax and consumption tax to finance the benefit are also examined.
