This paper studies in a quantitative way the macroeconomic and welfare effects of introducing progressive expenditure taxation, in a situation of the aging of the Japanese population. It undertakes a simulation analysis taking account of the general equilibrium effects of intragenerational inequality, which increases with a transition to an aging society. The simulation results suggest that progressive expenditure taxation has advantages over progressive labor income taxation on the grounds of efficiency and equity. Thus, a shift to progressive expenditure taxation can overcome the large welfare loss that would occur under the current tax system as Japan ages.
