This article quantifies the impact of H7N9 bird flu on chicken demand and consumer willingness to pay (WTP) in China. We measure risk perception, fear and trust against actual reduction in consumption and stated change in WTP for safe chicken between 2012 and 2013. Through a survey conducted in each year on the same Chinese urban consumers, we found that the consumption of chicken never increased after the emergence of H7N9 in 2013, and WTP for safe chicken did not necessarily increase relative to generic risks associated with consuming chicken in 2012. Factors such as the fear of H7N9's spreading, the impact of distrust (especially the distrust in government) enhanced the deviation of consumption and WTP; and the sheer mentioning of H7N9 is more important and negative than whether it was associated with a risk-perception reducing or risk-perception elevating message given to consumers.
本文量化了H7N9禽流感对中国鸡肉需求和消费者支付意愿(WTP)的影响。我们针对2012年至2013年期间鸡肉实际消费量的减少以及安全鸡肉支付意愿的既定变化,衡量了风险认知、恐惧和信任程度。通过每年对相同的中国城市消费者进行调查,我们发现2013年H7N9出现后鸡肉消费量从未增加,且相对于2012年食用鸡肉所涉及的一般风险,安全鸡肉的支付意愿不一定会提高。对H7N9传播的恐惧、不信任的影响(尤其是对政府的不信任)等因素加剧了消费量和支付意愿的偏差;而且仅仅提及H7N9比向消费者传达的信息是降低风险认知还是提高风险认知更为重要且负面影响更大。
