Nutrient Elasticities in a Complete Food Demand System
开发了一种方法，通过食品需求变化来测量营养素可获得性的变化，并利用需求弹性估计了十五种营养素对三十五种食品价格和人均收入变化的弹性。
Abstract This study explores the linkage of the determinants of food choice with consumer nutrient availability by developing a procedure to measure changes in nutrient availability as the demand for food items change. It uses demand elasticities from traditional demand analysis to estimate elasticities of changes in the nutritional content of consumer diets. The procedure is applied to estimate nutrient elasticities for fifteen nutrients in response to changes in thirty‐five food prices and per capita income.
