Labeling Context and Reference Point Effects in Models of Food Attribute Demand
研究食品标签如何通过情境和参考点影响消费者对转基因食品的需求，发现标签情境效应虽小但存在，而参考依赖是重要因素且随消费者特征变化。
There is considerable interest in the effect of labels on food product demand. Labeling statements may convey new information about attributes and place consumers in different choice contexts; consumers' assessment of information in labels may be affected by reference points. We examine labeling context relating to genetically modified (GM) food as a factor in the stochastic component of a random utility model and assess reference points over a set of observable characteristics of consumers. We find that labeling context effects are present, although relatively small, while reference dependence is a very important factor that varies over observable characteristics of the sampled consumers.
