Outline of Final Research Achievements

This research aims at broadening the framework of the traditional welfare economics, by exploring the possibility of the capability approach in the welfare economics. Concretely, first, we widen the domain of the Sennian social welfare functional and investigate the normative characteristics of the social relation function which is formulated with the capability indexes, second, we construct an individual’s capability set through aggregating achievement vectors of individuals who have similar utilization abilities and resources and different evaluation functions, which are freely chosen according to their own evaluations. We have the following results: having information on capabilities of order women, persons with limited sights and patients with home care services is a clue for making consensus and common understanding among residents in general with regard to more efficient and fairer distributional methods of resources.
