Using Neoclassical Consumer-Choice Theory to Produce a Market Map From Purchase Data
基于新古典消费者选择理论，提出一个从个人或家庭实际购买行为中估计商品空间位置和偏好向量的模型，整合了购买何种商品及购买数量的决策，并用番茄酱品牌扫描数据演示了参数估计方法。
This article presents a new model for estimating the spatial representation of objects and preference vectors from actual choice behavior of individuals or households. It is based on neoclassical economic theory of consumer choice. The model integrates both decisions of which good(s) to buy and the quantity of purchase. Overall preference is decomposed into price effects and intrinsic preference for the good. A maximum likelihood method for estimating the model parameters is described and illustrated using choice data of ketchup brands collected by the use of electronic supermarket scanners.
