摘要

我们跟踪了2019年9月至2020年9月在亚马逊上销售的所有口罩，并分析了卖家生成的产品信息以及用户生成的评论。通过一项完全动态的事件研究，我们发现，在第一次消费者评论或问答表明口罩是中国制造而不是其他国家制造后，口罩的平均用户评分显著下降。这种下降在中国产品被识别后的前三周有所扩大，但随后在12周内逐渐消失。u型帖子识别是由评论对平均评级的直接（自己的评级）和间接（其他消费者的评级）影响来解释的，并且是由具有高声誉的中国产品驱动的。通过分析消费者评论，我们提供了强有力的证据，证明平均评分的下降是由消费者对中国和中国产品的敌意造成的，而不是产品质量或运输。

Covid19 and consumer animus towards Chinese products: Evidence from Amazon data

We tracked all facemasks sold on Amazon from Sep. 2019 to Sep. 2020 and analyzed seller-generated product information as well as user-generated reviews. Using a fully dynamic event study we found the average user rating of a facemask dropped significantly following the first consumer review or question and answer stating it was made in China, but not of other countries. This drop expanded in the first three weeks after the identification of Chinese products but then gradually faded out within twelve weeks. The U-shape post identification is explained by a review’s direct (its own rating) and indirect (other consumers’ ratings) impact on average rating and was driven by Chinese products with high reputation. By analyzing consumer reviews, we provided strong evidence that the drop in average rating was driven by consumer animus to China and Chinese products rather than product quality or shipping.

期刊介绍： The Journal of Economic Behavior and Organization is devoted to theoretical and empirical research concerning economic decision, organization and behavior and to economic change in all its aspects. Its specific purposes are to foster an improved understanding of how human cognitive, computational and informational characteristics influence the working of economic organizations and market economies and how an economy structural features lead to various types of micro and macro behavior, to changing patterns of development and to institutional evolution. Research with these purposes that explore the interrelations of economics with other disciplines such as biology, psychology, law, anthropology, sociology and mathematics is particularly welcome.
