An Inverse Demand System for U.S. Composite Foods
构建了一个理论一致的逆需求系统，利用距离函数及其替代和规模效应，估计了美国13类食品和1类非食品的价格依赖需求。
Abstract This article provides a theoretically consistent framework for estimating a complete price dependent demand system, where the concept of distance function and its related substitution and scale effects are used. The approach is applied to a U.S. demand system consisting of thirteen food and one nonfood categories.
