印度经济学家阿马蒂亚·森通过实证研究,在《贫困与饥荒———论权利与剥夺》一书中阐述了贫困发生的原因以及与权利的相互关系,说明饥荒发生不是由于粮食严重短缺的缘故或者其他意想不到的天灾人祸,而是人们交换权利的严重不足。其中能力不足是产生交换权利缺乏的直接原因。交换权利的匮乏直接导致了贫困,但贫困却并非都是由交换权利的缺乏所引起。 Indian economist Amartya Sen through empirical research in the “Poverty and famine - on the right and deprivation,” a book set out the reasons for the occurrence of poverty and the relationship with the rights that the famine is not due to serious food Shortages, or other unexpected natural disasters, but a serious lack of human rights of exchange. Among them, lack of capacity is the direct reason for the lack of exchange rights. The lack of exchange of rights leads directly to poverty, but not all poverty is caused by the lack of exchange of rights.
