英文文献摘要：
Using experimental auctions, this paper evaluates the impact of information on consumers’ willingness to pay (WTP) for nano-packaged food products. Positive, negative and neutral information about the risks and benefits of nanotechnology in food processing was presented to consumers to measure the influence of information on consumer WTP. Double hurdle model results show that the specific information about nanotechnology from various sources has a negative effect on the probability of consumers valuing nano-packaged products. For consumers who did value nano-packaged products, general and specific information about nanotechnology had a positive effect on their WTP for nano-packaged salad and apple sauce. The effects of information on the WTPs of consumer who valued the products were more idiosyncratic, varying across the type of product, prior knowledge about nanotechnology, age, income, gender, marital status, and education.

利用实验拍卖，本文评估了信息对消费者购买纳米包装食品意愿的影响。向消费者提供了关于食品加工中纳米技术的风险和好处的积极、消极和中立信息，以衡量信息对消费者期望值的影响。双障碍模型的结果显示，来自不同来源的关于纳米技术的特定信息对消费者评价纳米包装产品的概率有负面影响。对于那些确实重视纳米包装产品的消费者，关于纳米技术的一般和特定信息对他们对纳米包装沙拉和苹果酱的期望值有积极的影响。信息对评价产品的消费者的WTPs的影响更为特殊，在产品类型、关于纳米技术的先验知识、年龄、收入、性别、婚姻状况和教育程度等方面存在差异。
