Self-Selection and the Redistributive Impact of In-Kind Transfers: An Econometric Analysis
研究牙买加学校供餐计划中，贫困家庭更可能自我选择参与，但实物转移的低质量导致较大无谓损失，评估了自我选择对再分配的影响。
Self-targeting welfare programs have received increasing attention from economists and policymakers alike. This paper provides evidence on the redistributive impact of transferring low-quality goods in-kind. I study a school feeding program in Jamaica, which distributes a bland snack to all students. Poorer households and those with a greater number of eligible children are found significantly more likely to self-select into the program. But, against these targeting benefits is a large estimated dead-weight loss.
