| 内容提要 | 针对消费者在选购转基因食品时所面临的模糊性，传统基于冯诺依曼选择公理体系下的研究方法不再适用。为了探求消费者的行为成因，同时考察消费者理论中弹性这一概念的变化，本文利用了解决不确定状态下的决策模型——CEU模型来考察消费者的行为成因，同时对比了传统OEU模型和CEU模型在消费行为中收入阈值差异。此外还比较了两种模型下的Slutsky替代矩阵，CEU模型充分考虑了决策人在面临模糊性事件时的模糊性感知和模糊性态度参数，成为两种选择公理体系下替代矩阵差异的关键。通过参数讨论，在检验CEU模型下的Slutsky替代矩阵同样满足传统模型的一些基本性质后，本文给出了不同情况下不同模型对于替代效应的高估和低估情况，对于政府推广转基因食品具有重要的政策含义。 |
| Abstract | According to the ambiguity of consumers in choosing genetically modified foods(GMF), traditional research methods based on VNM no longer apply. In order to find out reason of consumers’ behavior as well as the concept of elastic theory, this article tries to solve this problem by the method of CEU model, we compared the traditional OEU model and CEU model and find the differences in income threshold, meanwhile we compute the Slutsky substitution matrix of the two models. The two parameter included in CEU model: self-confidence and optimism level, made the difference between the CEU model and traditional OEU model. After discussing the parameter, we find the linear relationship of Slutsky substitution matrix under two models and figure out the estimation of substitution, which is onducive to policy makers for the policy making of GMF. |
