利用私营部门调查数据估计2011年后印度的贫困状况

Estimating poverty for India after 2011 using private-sector survey data
Journal of Development Economics · 2024 · Sutirtha Sinha Roy、Roy van der Weide

中文摘要

印度国家抽样调查组织最近一次公布的支出调查可追溯至2011年,该调查是最近一次官方贫困与不平等估计的依据。本文采用一种新方法,利用私营部门开展的一项新近可用的住户面板调查,估计印度自2011年以来贫困与不平等的变化轨迹。结果提示:(1)据估计,2019年的极端贫困水平低于2011年,农村地区的贫困减少幅度可能更大;(2)2016年城市贫困可能有所上升,时间上与废钞事件重合。这些结果不应被解读为确凿证据。尽管估计得到的贫困变化趋势与一系列佐证证据相符,但由于私营部门调查存在抽样误差与非抽样误差,仍存在较大的不确定性。

Abstract

The last expenditure survey released by India’s National Sample Survey organization dates back to 2011, which underpins the last official estimates of poverty and inequality. This paper adopts a new approach to estimate India’s poverty and inequality trajectory since 2011 using a newly available household panel survey conducted by the private sector. The results suggest that (1) extreme poverty is estimated to be lower in 2019 than in 2011, with greater poverty reductions likely in rural areas, and (2) coinciding with the demonetization event, urban poverty likely rose in 2016. The results should not be interpreted as definite proof. While the estimated trends in poverty sit well with a range of corroborative evidence, significant uncertainty remains stemming from sampling and non-sampling errors associated with the private-sector survey.
