摘要水产养殖业和所有的动物生产一样，也容易受到疾病的影响，这些疾病会造成负面的宣传和市场影响。最近的一个例子是智利鲑鱼养殖业，由于爆发传染性鲑鱼贫血症，该行业目前正面临前所未有的经济损失。我们进行了两项消费者实验，以调查负面宣传对消费者对来自未受影响国家和物种的海鲜产品的评价的溢出效应，以及受影响行业可能使用的潜在缓解策略。我们发现，在未受影响的国家生产的相同物种和在受影响的国家内养殖的其他鱼类物种受到重大的负面溢出效应。我们还发现，与高档零售商建立品牌联系并不能提高消费者的价值（即，没有积极的溢出效应）。JEL分类代码：Q13、Q22。
Abstract Aquaculture, as all animal production, is exposed to diseases which can cause negative publicity and market impacts. A recent example is the Chilean salmon farming industry, which is currently facing unprecedented economic losses due to an outbreak of infectious salmon anemia. We conducted two consumer experiments to investigate spillover effects of negative publicity on consumer valuation of seafood products from unaffected countries and species, as well as a potential mitigating strategy that an affected industry might use. We find significant negative spillover effects on the same species produced in unaffected countries and on other fish species farmed within the affected country. We also find that building a brand association with an upscale retailer does not improve the consumer valuation (i.e., no positive spillover effects) for products from directly and indirectly affected countries of the affected species. JEL Classification Codes: Q13, Q22.
