The Economic Lives of the Poor
基于13国调查数据，描述了日均生活费低于2美元（购买力平价）的穷人的消费、收入模式及市场与公共基础设施的获取情况，并讨论了若干看似反常的选择。
This paper uses survey data from 13 countries to document the economic lives of the poor (those living on less than $2 dollar per day per capita at purchasing power parity) or the extremely poor (those living on less than $1 dollar per day). We describe their patterns of consumption and income generation as well as their access to markets and publicly provided infrastructure. The paper concludes with a discussion of some apparent anomalous choices.
