中文摘要

本文以1984年埃塞俄比亚饥荒的粮食援助应对为案例研究,考察紧急粮食援助对健康状况的长期缓解影响。本文采用关于紧急粮食发放救济营地位置的新型地理空间数据,估计邻近救济营地对成年后身高的影响。我们比较了不同出生时间(出生于救济行动之前或期间与出生于行动之后)和不同出生村庄(出生地邻近救济营地与远离救济营地),利用紧急援助可及性中可合理视为外生的变异进行识别。幼儿期获得救济行动的援助会使成年后身高更高。援助受益者在日后的农业部门劳动生产率也更高,这表明紧急援助带来的长期健康影响可能已转化为农业生产率的提高。

Abstract

We examine the long-term mitigating impact of emergency food aid on health status using the food aid response to the Ethiopian famine in 1984 as a case study. Employing novel geospatial data on the location of relief camps where emergency food was distributed, we estimate the effect of proximity to a camp on height in adulthood. We compare different birth timings (born before or during versus after the relief operation) and different villages of birth (born close to versus far from a camp), exploiting plausibly exogenous variation in accessibility to emergency aid. Access to relief operation in early childhood leads to higher stature in adulthood. Aid beneficiaries also display higher later-life labor productivity in the agricultural sector, which suggests that the long-term health consequence of emergency aid may have translated into gains in agricultural productivity.
