发展中国家普遍存在的营养不良现象要求采取适当的战略，前提是充分了解政策对营养的影响。以前很少在这方面开展工作，特别是在微量营养素方面。我们使用代表性的家庭数据从马拉维和开发一个需求系统的方法来估计收入和价格弹性的粮食需求和营养消费。这些估计数用于政策模拟。鉴于存在多种营养缺陷，与收入有关的政策比价格政策更适合改善营养状况。虽然对玉米的消费者价格补贴改善了卡路里和矿物质的消费，但可能使城市地区的维生素消费恶化。(C)2010爱思唯尔有限公司版权所有。
Widespread malnutrition in developing countries calls for appropriate strategies, presupposing good knowledge about nutritional impacts of policies. Little previous work has been carried out in this direction, especially with respect to micronutrients. We use representative household data from Malawi and develop a demand systems approach to estimate income and price elasticities of food demand and nutrient consumption. These estimates are applied for policy simulations. Given multiple nutritional deficiencies, income-related policies are better suited than price policies to improve nutrition. While consumer price subsidies for maize improve calorie and mineral consumption, they can worsen vitamin consumption in urban areas. (C) 2010 Elsevier Ltd. All rights reserved.
