本文概述了减少发育迟缓的投资的经济原理。我们提出了一个框架，说明了在整个生命周期的概念后1000天发育迟缓的功能后果：从童年到老年。我们总结了生命周期中每个环节的关键经验文献，突出了知识的差距。我们构建了一套合理的营养干预措施，以减少发育迟缓的效益-成本比的可靠估计。我们记录了在这样做的过程中存在的相当大的挑战。我们假设，由于预防了五分之一的发育迟缓，未来利益流的贴现率为5%，收入将提高11%。我们对17个高负担国家减少发育迟缓的投资的国别效益成本比的估计从3.6（刚果民主共和国）到48（印度尼西亚）不等，中值为18（孟加拉国）。考虑到这些结果取决于一些假设，与公共资金竞争的其他投资相比，它们是有利的。
This paper outlines the economic rationale for investments that reduce stunting. We present a framework that illustrates the functional consequences of stunting in the 1000 days after conception throughout the life cycle: from childhood through to old age. We summarize the key empirical literature around each of the links in the life cycle, highlighting gaps in knowledge where they exist. We construct credible estimates of benefit-cost ratios for a plausible set of nutritional interventions to reduce stunting. There are considerable challenges in doing so that we document. We assume an uplift in income of 11% due to the prevention of one fifth of stunting and a 5% discount rate of future benefit streams. Our estimates of the country-specific benefit-cost ratios for investments that reduce stunting in 17 high-burden countries range from 3.6 (DRC) to 48 (Indonesia) with a median value of 18 (Bangladesh). Mindful that these results hinge on a number of assumptions, they compare favourably with other investments for which public funds compete.
