Preference heterogeneity and GM food in the UK
用混合logit模型重新分析选择实验数据，发现消费者对转基因食品的偏好存在异质性，并模拟了不同折扣下愿意购买的消费者比例。
This study uses mixed logit models to reconsider the findings of choice experiment surveys with a focus on heterogeneity among consumers. The motivation is that these techniques allow the researcher to segment the market better. This is critical because it is not the average attitude or preference that is important, but the size of the groups who will be prepared to accept the product under certain circumstances. The causes of heterogeneity within the sample are investigated and the proportions of consumers willing to buy GM foods at various discounts are simulated. © Oxford University Press and Foundation for the European Review of Agricultural Economics 2005; all rights reserved.
