| Outline of Final Research Achievements |
In an overlapping generations model, where time is required for consumption of private goods and utilization of excludable public goods and where the time constraint of the old generation is not binding, this study explored whether the discriminative policy of the intergenerational user charges on the public goods advatageous to the elderly in Japan is socially disirable. The modified Ramsey rule on labor and capita income taxes and the charges were derived. In order to clarify charachteristics of this rule, the log-linear utility was assumed and the following results were obtained. If time is necessary for consumption of the private goods, the government should impose a charge and a labor income tax on the young generation to finance public expenditure. However, it sould not impose a charge and a capital income tax on the old. Otherwise, capital income should be subsidized and charges should be imposed on both generations.
