Fruit and Vegetable Consumption Patterns: A Segmentation Approach
使用有限混合AIDS模型分析法国水果蔬菜消费的异质性，识别出六个具有不同社会经济特征和价格收入弹性的消费群体，为精准营养政策提供依据。
Abstract In this article, we study the heterogeneity of fruit and vegetable consumption patterns in France. A finite mixture of AIDS models is used to describe food demand patterns revealing different preferences over distinct classes. We obtained six different clusters, which reflect specific socio‐demographic characteristics and different income and price elasticities. This approach is appropriate for targeting specific public nutritional policies. Our main results show that unlike the other clusters in which the usual price and income policy tools may be used, the lowest income cluster with the lowest consumption, remains insensitive to economic variables.
