关于森的贫困度量方法及该领域最近的研究进展

在这篇文章中,我们应用贫困度量的公理化方法对森的贫困指数提出了一个统一的理论框架.这一理论框架清晰地表明,这些指数与一个特定的社会福利函数之间存有密切的联系,而且,我们发现这些指数具有相同的可分的乘积结构.因为这个性质,这些指数无论是从直观的角度还是从几何学的角度都更加便于理解,同时也更便于计算.这些发现使森的贫困指数可以直接在发达国家和发展中国家的扶贫政策分析和政策制定过程中得到应用.

ON SEN'S APPROACH TO POVERTY MEASURES AND RECENT DEVELOPMENTS

In this paper we discuss the axiomatic approach to poverty mea- sure and propose a unified framework for the Sen indices of poverty intensity which shows an explicit connection between the indices and their common underlying so- cial evaluation function, we also identify the common multiplicative decomposition of the indices that allows simple and similar geometric interpretations and easy numerical computation. These results are easy to understand and useful to policy makers in both developed and developin...
