Consumer Benefits of Labels and Bans on GM Foods—Choice Experiments with Swedish Consumers
通过瑞典消费者的选择实验，检验转基因食品禁令是否因负外部性而合理，发现消费者对禁令和标签方案的支付意愿无显著差异。
The European Union has been relatively cautious about using biotechnology in food production. A label regime combined with the right of individual member states to ban introduction of new genetically modified (GM) strains means that GM food products in effect are banned in many countries. We show how it is possible to empirically test whether a ban can be motivated by reference to potential negative externalities. This is followed up by results from a choice experiment. We cannot reject the hypothesis of equal WTP for a ban and a labeling scheme.
