This paper explores the implications of using two methodological approaches to study poverty dynamics in rural Bangladesh. Using data from a unique longitudinal study, we show how different methods lead to very different assessments of socio-economic mobility. We suggest five ways of reconciling these differences: considering assets in addition to expenditures, proximity to the poverty line, other aspects of well-being, household division, and qualitative recall errors. Considering assets and proximity to the poverty line along with expenditures resolves three-fifths of the qualitative and quantitative differences. Use of such integrated mixed-methods can therefore improve the reliability of poverty dynamics research.
本文探讨了在研究孟加拉国农村贫困动态时使用两种方法论的意义。我们利用一项独特的纵向研究的数据,展示了不同方法如何导致对社会经济流动性的评估大相径庭。我们提出了五种调和这些差异的方法:除支出外还考虑资产,接近贫困线,福祉的其他方面,家庭划分和定性回忆错误。将资产和接近贫困线与支出一起考虑,可以解决五分之三的定性和定量差异。因此,使用这种综合混合方法可以提高贫困动态研究的可靠性。
