Targeting at the Margin: the ‘Glass of Milk’ Subsidy Programme in Peru
评估秘鲁Vaso de Leche喂养计划的瞄准效率，发现中央政府按地区选择贫困者的效果优于地方政府和社区委员会，但按转移价值衡量时社区决策者反而更精准。
This article evaluates the Vaso de Leche (VL) feeding programme in Peru in order to illustrate an evaluation methodology based on targeting criteria for a decentralised transfer programme. We find that the degree of overall targeting of poor individuals attributable to the central government's choice of districts is greater than that attributable to choice of participants within districts made by the municipalities and the mothers' committees. However, when we use a version of a targeting efficiency measure first introduced by Galasso and Ravallion [2003] which we modify to be defined on the values of allocations, the opposite is the case. The community-based decision makers appear to be targeting the poor in terms of the values of the transfers.
