Food Inflation and Child Health
利用埃塞俄比亚调查数据，研究发现胎儿期和婴儿期经历食品价格月涨1个百分点，五岁以下儿童发育迟缓风险增加0.95%，且影响因暴露月份而异。
Abstract Malnutrition is one of the most important early life shocks that have lasting effects on health. An often neglected cause of malnutrition and hidden hunger is high food inflation, particularly in developing countries. This study uses the Ethiopian Demographic and Health Survey data, matching each child's early life age in months from the time of conception with the corresponding local monthly food price data to examine the medium-term and long-term impacts of exposure to food inflation during the critical early life window—pregnancy and infancy—on child health. Exposure to one percentage point higher month-to-month food inflation while in utero increases the risk of under-five stunting by 0.95 percent. The impacts are heterogeneous depending on the month of exposure, highlighting the complicated biological mechanisms through which malnutrition during early life affects human growth. The results are robust to various empircal specifications and potential biases arising from survivor sample selection and age misreporting.
