中文摘要
社会救助项目可以增加消费、减少贫困，但对于这些影响能否在项目结束后持续，以及设计与情境如何影响其可持续性，我们知之甚少。利用孟加拉国两个地区在一项随机干预结束四年后收集的数据，我们发现，将现金转移与配套项目相结合，带来了消费的持续增加和贫困的持续减少。将食物转移与配套项目相结合也呈现出类似但程度较弱的模式。单独现金转移具有因情境而异的持续效应；单独食物转移则没有持续影响。结果表明，情境、转移方式和配套项目对持续影响具有重要作用。（JEL D12, E21, I32, I38, O15）
Abstract
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. (JEL D12, E21, I32, I38, O15)
