贫穷可以有许多不同的形式，在消费或收入等货币方面和健康和教育等非货币方面都有很大的差别。衡量贫穷的一大类非货币指标是多维贫穷指数;最近的研究表明，在一个方面被确定为贫穷的人往往不同于在另一个方面被确定为贫穷的人。本文通过研究MDP动态是否类似于相关的消费为基础的贫困措施的动态，扩展了文献。使用两波埃塞俄比亚面板数据（2011-12年和2013-14年），我们根据真实的消费的货币价值和非货币加权贫困指数（我们对MDP的基本衡量标准）来估计贫困。与对其他国家的研究类似，我们发现，这两种贫困估计数确定了明显不同的埃塞俄比亚贫困群体。本文的一个关键贡献是发现消费的变化在很大程度上独立于多维幸福的变化：意识到一个人的幸福随着时间的推移而改善，通过加权剥夺指数的改善来衡量，并没有提供关于他或她的幸福是否在消费方面有所改善的信息。
Poverty can take many different forms, ranging widely over dimensions both monetary, such as consumption or income, and nonmonetary, such as health and education. One large class of nonmonetary measures of poverty is the multidimensional poverty index (MPI); recent studies document that people identified as poor in one dimension are often different from those who found to be poor in another dimension. This paper extends the literature by examining whether MDP dynamics are similar to the dynamics of a related consumption based measure of poverty. Using two waves of Ethiopian panel data (2011-12 and 2013-14) we estimate poverty based on a monetary value of real consumption and a non monetary weighted deprivation index (our underlying measure of MDP). Similar to studies for other countries, we find that the two estimates of poverty identify significantly different groups of Ethiopians as poor. A key contribution of this paper is the finding that changes in consumption are largely independent of changes in multidimensional wellbeing: Awareness that an individual’s wellbeing improved over time as measured by improvements in the weighted deprivation index provides no information about whether his or her well being has improved where consumption is concerned.
