Reducing Child Malnutrition
利用12个国家家庭调查数据和跨国时间序列数据，研究发现收入增长对降低儿童营养不良率的作用有限，实现联合国千年发展目标需要收入增长与直接干预措施并重。
How rapidly will child malnutrition respond to income growth? This article explores that question using household survey data from 12 countries as well as data on malnutrition rates in a cross-section of countries since the 1970s. Both forms of analysis yield similar results. Increases in income at the household and national levels imply similar rates of reduction in malnutrition. Using these estimates and better than historical income growth rates, the article finds that the Millennium Development Goal of halving the prevalence of underweight children by 2015 is unlikely to be met through income growth alone. What is needed to accelerate reductions in malnutrition is a balanced strategy of income growth and investment in more direct interventions.
