The Demand for Calories in Developing Countries
运用特征需求理论估计发展中国家卡路里需求函数，发现即使价格不变且收入分配不恶化，仅靠历史收入增速无法在15年内满足全体人口的食物需求。
Abstract This paper employs characteristic demand theory to estimate demand functions for calories for a set of developing countries and to investigate the potential impact of income growth, redistribution, and price changes on alleviating underconsumption of calories. The analysis finds that, although calorie elasticities with respect to income are substantial for the poorer consumers, income growth above historical rates is required for the food needs of the entire population to be satisfied within the next fifteen years, even if calorie prices remain constant and income distribution does not become more unequal.
