Estimating the Public Value of Conflicting Information: The Case of Genetically Modified Foods
通过实验拍卖发现，环保组织传播的负面信息显著降低了美国消费者对转基因食品的需求，并产生了每年约20亿美元的公共价值，而第三方独立信息则削弱了这一价值。
<i>Environmental groups have become the chief antagonists toward agricultural biotechnology innovations. They demonstrate and disseminate private information with the objective of changing the behavior of consumers and producers. We use experimental auctions with adult U.S. consumers and show that this information reduces significantly the demand for genetically modified (GM)-food products and that it has significant public good value—an average of 3 cents per product purchased, or roughly $2 billion annually. We also show that the dissemination of independent third-party information about agricultural biotechnology dissipates most of the public good value of negative GM-product information</i>.
