Abstract

This paper examines the causal link between early childhood nutrition and cognition, applying instrumental variables to sibling-differences for a sample of pre-school aged Peruvian children. Child-specific shocks in the form of food price changes and household shocks during the critical developmental period of a child are used as instruments. The analysis shows significant and positive returns to early childhood nutritional investments. An increase in the Height-for-Age z-score of one standard deviation - keeping other factors constant - translates into increases in the Peabody Picture Vocabulary Test (PPVT) score of 17-21 percent of a standard deviation. The period of analysis includes the recent global food price crisis that also affected Peru between 2006 and 2008. This therefore is also a quantification of the nutritional and subsequent cognitive costs of food prices on the sample, which could be magnified in later years.
秘鲁的早期营养与认知
本文考察了幼儿营养和认知之间的因果关系,将工具变量应用于秘鲁学龄前儿童的兄弟姐妹差异样本。以食品价格变化和儿童发育关键期家庭冲击为形式的针对儿童的冲击被用作手段。分析显示,早期儿童营养投资取得了显著的积极回报。在保持其他因素不变的情况下,身高年龄比z分数增加一个标准差,就会导致皮博迪图片词汇测试(PPVT)分数增加17- 21%的标准差。分析期间包括最近的全球粮食价格危机,该危机也在2006年至2008年期间影响了秘鲁。因此,这也是对食品价格对样本的营养和随后的认知成本的量化,这可能在以后的几年里被放大。
