现金与实物:卢旺达儿童营养项目与无条件现金转移的基准比较

Cash Versus Kind: Benchmarking a Child Nutrition Program Against Unconditional Cash Transfers in Rwanda
The Economic Journal · 2024 · Craig McIntosh、Andrew Zeitlin

中文摘要

我们开发了一种方法,用于将实物项目与成本相同的现金转移进行基准比较。在应用该方法时,我们将一项多维儿童营养干预与无条件现金转移进行比较,利用转移金额的随机变化以及对支出进行的回归调整,估计与实物项目成本相同的现金转移的影响,以及增加现金转移金额的回报。尽管实物项目和与其成本相同、每户成本为124美元的现金转移均未在一年内改变儿童的核心结果指标,但现金转移带来的消费和资产积累更高,且差异具有统计显著性。一项成本为517美元的更大规模现金转移大幅改善了消费和投资结果,并使膳食多样性和儿童生长得到适度改善。

Abstract

Abstract We develop a methodology to benchmark in-kind programs against cost-equivalent cash transfers. Our application compares a multi-dimensional child nutrition intervention to unconditional cash transfers, using randomised variation in transfer amounts and regression adjustment of expenditures to estimate impacts of cash transfers at identical cost as well as to estimate the return to increasing cash transfer amounts. While neither the in-kind program nor a cost-equivalent transfer costing $124 per household moves core child outcomes within a year, cash transfers create significantly greater consumption and asset accumulation. A larger cash transfer costing $517 substantially improves consumption and investment outcomes and drives modest improvements in dietary diversity and child growth.
