Cash Transfers, Food Prices, and Nutrition Impacts on Ineligible Children
研究发现菲律宾的家庭定向现金转移提高了部分市场易腐食品价格，使非受益儿童发育迟缓率上升11个百分点（34%），且影响在村庄收入冲击大和偏远地区更显著，表明现金转移可能产生负面溢出效应。
Abstract Can cash aid harm nonrecipients by raising local prices? We show that a household-targeted cash transfer in the Philippines increases the prices of perishable foods in some markets and raises stunting among nonbeneficiary children by 11 percentage points (34%). Impacts increase in the size of the village income shock and remoteness---and are sustained two and a half years after program introduction. Price effects from an experimental sample are confirmed with national expenditure surveys collected during program scale-up. Household-targeted cash transfers can thus generate local spillovers that undermine program goals. Selected geographic targeting may avoid price spillovers at moderate additional cost.
