如果贫困人口的绝对数量上升了，但贫困人口的比例下降了，那么贫困是上升了还是下降了？经济学家的直觉是，在人口复制公理的框架下，贫困的标准措施，是说，在这种情况下，贫困已经下降。但这违背了那些直接与穷人打交道的人的本能，对他们来说，绝对数字的概念更有意义，因为他们在街头或施舍处科普更多的穷人。本文试图把这两个概念的贫困纳入一个共同的框架。具体而言，它提出了一个不言自明的发展家庭的贫困措施，没有人口复制公理。这一系列与标准衡量标准有着直观的联系，但它也允许通过选择相关参数，对“绝对数字”或“贫困比例”概念中的一个或另一个给予更大的权重。我们希望这一系列的研究能在实证和政策研究中证明是有用的，因为在这些研究中，经济学家和实践者对贫困的看法都是重要的。
If the absolute number of poor people goes up, but the fraction of people in poverty comes down, has poverty gone up or gone down? The economist’s instinct, framed by population replication axioms that undergird standard measures of poverty, is to say that in this case poverty has gone down. But this goes against the instinct of those who work directly with the poor, for whom the absolute numbers notion makes more sense as they cope with more poor on the streets or in the soup kitchens. This paper attempts to put these two conceptions of poverty into a common framework. Specifically, it presents an axiomatic development of a family of poverty measures without a population replication axiom. This family has an intuitive link to standard measures, but it also allows one or other of “the absolute numbers” or the “fraction in poverty” conception to be given greater weight by the choice of relevant parameters. We hope that this family will prove useful in empirical and policy work, where it is important to give both views of poverty—the economist’s and the practitioner’s—their due.
