Sustainable Poverty Reduction through Social Assistance: Modality, Context, and Complementary Programming in Bangladesh
基于孟加拉国两个地区随机干预结束四年后的数据，研究发现现金转移与补充项目结合能持续提高消费并减少贫困，而单独现金的效果因背景而异，单独食品则无持续影响。
Social assistance programs can increase consumption and reduce poverty, but less is known about whether these impacts are sustained after programs end or how design and context influence sustainability. Using data collected in two regions of Bangladesh four years after a randomized intervention ended, we find that combining cash transfers with complementary programming led to sustained increases in consumption and reductions in poverty. Combining food transfers with complementary programming showed similar patterns to a lesser extent. Cash alone had context-specific sustained effects; food alone had no sustained impacts. Results suggest that context, modality, and complementary programming matter for sustained impacts.
