Cereal Prices and Child Undernutrition in Ethiopia
利用埃塞俄比亚生活标准测量调查数据，研究发现谷物价格上涨与6个月至5岁儿童的身高别年龄（发育迟缓）改善正相关，但与体重别身高（消瘦）无关，且对净销售家庭儿童无显著额外影响。
This paper looks at how changing cereal prices affect child undernutrition in Ethiopia. It derives height for age (stunting) and weight for height (wasting) as indicators of child undernutrition from the two most recent years of the Living Standards Measurement Survey and utilises market prices for key cereals, teff, wheat, and maize in enumeration areas across all regions of the country. Using a panel data fixed effects model, the analysis finds that, contrary to previous studies, rising cereal prices are positively associated with improved child stunting rates for children between ages 6 months and 5 years. There is no evidence to suggest that cereal prices have a significantly greater impact on height for age for children that come from households who are net sellers of these crops. Cereal prices do not appear to be associated with wasting, which is a short-term negative health outcome.
