论文摘要
在这项研究中，我们扩展了有关动态贫困指数的研究，即动态成员比率，动态收入差距比，动态Gini和动态SEN，在D'Amico和Regnault中提出的动态SEN（2018）。贡献是双重的。首先，我们扩展了动态吉尼指数的计算，因此，随着在每个贫困阶段的不平等，人们根据收入分类。其次，对于每个贫困指数，我们建立一个中心限制定理，使我们有可能确定置信度集。从1998年到2012年的意大利收入数据的应用证实了所考虑的方法的有效性，以及确定实际经济体贫困和不平等进化的可能性。
In this study, we extend the research on the dynamic poverty indexes, namely the dynamic Headcount ratio, the dynamic income-gap ratio, the dynamic Gini and the dynamic Sen, proposed in D'Amico and Regnault (2018). The contribution is twofold. First, we extend the computation of the dynamic Gini index, thus the Sen index accordingly, with the inclusion of the inequality within each class of poverty where people are classified according to their income. Second, for each poverty index, we establish a central limit theorem that gives us the possibility to determine the confidence sets. An application to the Italian income data from 1998 to 2012 confirms the effectiveness of the considered approach and the possibility to determine the evolution of poverty and inequality in real economies.
