本文使用Alkire Foster调整后的人数比率及其一致的子指数，系统地阐述了多维贫困的跨期变化。它使用三种技术来评估多层面减贫的扶贫性。对多维贫穷变化的分析借鉴了全球多维贫穷指数和34个国家和338个国家以下区域的相关贫穷衡量标准，涵盖25亿人，其中有最近的多维贫穷指数估计数和可比较的人口与健康调查数据集。首先，它评估了贫困及其发生率和严重程度的总体变化，并将其与1.90美元贫困的变化进行了比较。其次，利用分组可分解性的属性，它检查了MPI及其一致的子指数随着时间的推移在城市农村地区，次国家区域和族裔群体的变化。分解分析确定了相关的国家模式，包括最贫穷亚群体减贫速度较快的国家模式。最后，本文分析了一个严格的子集的穷人，谁被确定为“赤贫”使用更极端的剥夺截止矢量的动态，并研究了减少贫困和贫困的国家和地区的相对速度。这一广泛的实证分析说明了如何评估减少多层面贫穷的程度和模式，以及它是否具有包容性，或者是否有一些人或群体被抛在后面。自然，一些进一步的研究问题出现了。(C)2017爱思唯尔有限公司版权所有。
This paper sets out a systemic account of intertemporal changes in multidimensional poverty using the Alkire Foster Adjusted Headcount Ratio and its consistent sub-indices. It uses three techniques to assess the pro-poorness of multidimensional poverty reduction. The analysis of changes in multidimensional poverty draws on the global Multidimensional Poverty Index (MPI) and related destitution measure in 34 countries and 338 sub-national regions, covering 2.5 billion people, for which there is a recent MPI estimation and comparable Demographic and Health Survey (DHS) dataset across time. First, it assesses overall changes in poverty and its incidence and intensity, and compares this with changes in $1.90 poverty. Next, utilizing the property of subgroup decomposability, it examines changes in the MPI and its consistent sub-indices over time across urban rural regions, sub-national regions and ethnic groups. The decomposition analysis identifies relevant national patterns, including those in which the pace of poverty reduction is higher for the poorest subgroups. Finally, the paper analyzes the dynamics of a strict subset of the poor, who are identified as "destitute" using a more extreme deprivation cutoff vector, and studies relative rates of reduction of destitution and poverty by country and region. This extensive empirical analysis illustrates how to assess the extent and patterns of reduction of multidimensional poverty, as well as whether it is inclusive or whether some people or groups are left behind. Naturally, some further research questions emerge. (C) 2017 Elsevier Ltd. All rights reserved.
