中文摘要
我们研究了在布基纳法索实施的一项多层面项目的影响，该项目针对有幼儿或孕妇的赤贫家庭。项目设计包括现金转移（T1）、T1 加牲畜转移（T2），以及 T2 加营养包（包含强化面粉、园艺工具包和营养教育）（T3）。我们发现，该项目在所有处理分支中均降低了极端贫困，但只有 T3 对儿童营养产生了正向影响。T3 还影响了新生儿的运动和认知发展。我们的结果表明，尽管标准的多层面项目在减贫方面是有效的，但要通过改善认知技能更好地提升儿童的长期收入潜力，可能仍需要以营养为重点的项目。
Abstract
We study the impacts of a multifaceted program implemented in Burkina Faso that targets ultra-poor households with young children or pregnant women. The design includes a cash transfer program (T1), T1 plus animal transfer (T2) and T2 plus a nutrition bundle which includes fortified flour, a gardening kit and nutrition education (T3). We find that the program reduces extreme poverty in all treatment branches, but only T3 positively impacts child nutrition. T3 also impacts motor and cognitive development of new born children. Our results suggest that while standard multi-faced programs are effective at reducing poverty, nutritionally focused programs are likely necessary to better address children’s long-run earning potential via improved cognitive skills.
