Within-Cohort Inequality and Tax Reforms in an Aging Japan

  • Akira Okamoto


This chapter takes account of within-cohort inequality that increases in a transition to an aging society. The simulation model employed in this chapter is basically the same as that in Chap. 7. This chapter demonstrates the general equilibrium effects of an increasing variance in the lifetime income distribution with an aging Japanese population. It also studies the macroeconomic and welfare effects of introducing progressive expenditure taxation in this situation.
