A Conception of Global Welfare System based on the Formulation of Capability Approach

最近，在阿马蒂亚·森的指导下，福利经济学和相关领域迅速发展了规范性分析框架和方法，认真考虑到社会正义问题。本研究的目的是：第一，系统整理阿马蒂亚·森的经济学和哲学，特别是他的福利经济学，包括能力方法和社会选择理论;第二，重新概念化人的尊严、权利、福祉和制度，从理论和实践两个方面支持这些思想;第三，以公共理性为基础，建构民主制度所需的替代性政治经济制度。主要研究活动之一是2005年10月举行的“反对不公正-伦理、经济和法律”国际会议，会议不仅邀请了Amartya Sen，还邀请了规范经济学家、政治哲学家、性别理论家和法律哲学家的几位教授。它成功地创造了一个反映法与经济学关系的公共理性场合。这次会议的成果将作为一本书出版，Gotoh R。和P. Dumouchel（eds.）《反对不公正--阿马蒂亚·森的新经济学》，剑桥：剑桥大学出版社。另一个主要成果是一本书，Amartya Sen和Reiko Gotoh，Well-Being and Justice，东京大学出版社。在这两本书中所寻求的是重新审视福利政策，关注由阿马蒂亚·森开创的正在发展的新经济学视角。

Recently, under the stewardship of Amartya Sen, welfare economics and related areas have rapidly developed normative analytical frameworks and methodologies that take the issue of social justice into account seriously. The purpose of this research is first, to systematize Amartya Sen's Economics and Philosophy, especially his welfare economics including the capability approach and the social choice theory, second, to re-conceptualize the ideas of human dignity, right, well-being and institutions which can support these ideas in both terms of theory and practice, third, to construct alternative political and economic systems required for democratic system based on public reason. One of the main research activities is the International Conference “Against Injustice---Ethics, Economics and Law" held on October 2005, which invites not only Amartya Sen but also several professors of normative economists, political philosophers, gender theorists, and law philosophers. It succeeded in creating an occasion of public reasoning which reflects relationship between law and economics. The fruit of this conference will be published as a book, Gotoh R. and P. Dumouchel (eds.) Against Injustice - The New Economics of Amartya Sen, Cambridge: Cambridge University Press. Another main fruit is a book, Amartya Sen and Reiko Gotoh, Well-Being and Justice, Tokyo University Press. What have been sought in these two books is to take a new look at welfare policies paying attention of the developing new perspective of economics pioneered by Amartya Sen.
