内容摘要：

What explains consumer demand for counterfeits? We conduct a ZIP-code-level analysis based on 11 million counterfeit orders from a cross-border e-commerce platform in the U.S. We report three main findings. First, counterfeit demand exhibits a U-shaped pattern across the household income spectrum. Relative to middle-income consumers ($50k–100k), those in the bottom (<$15k) and top (>$150k) brackets are more active. They buy more counterfeits, favor higher-priced items, make repeat purchases, and experiment with new options. Second, counterfeit demand is strongly associated with cultural preferences captured by a behavioral trustworthiness index, derived from the unexplained component of credit scores. Finally, we identify severe information asymmetry in counterfeit markets. Because regulation restricts sellers’ disclosures, buyer reviews fill the information gap and sustain demand. We explore heterogeneities and discuss theoretical and practical implications.

消费者为何对假冒商品有需求？我们基于美国一个跨境电子商务平台的1100万份假冒订单，进行了邮政编码级别的分析。我们有三个主要的发现，首先，假冒商品的需求呈现出U形分布。具体来说，与中等收入群体（年收入5万至10万美元）相比，低收入群体（年收入低于1.5万美元）和高收入群体（年收入超过15万美元）对假冒商品的需求更为活跃。他们购买更多假冒商品，偏好价格较高的产品，经常重复购买，并尝试新的选择。此外，假冒商品的需求与文化偏好密切相关，这些偏好通过一个行为可信度指数来衡量，该指数来源于信用评分中未解释的部分。最后，我们发现假冒商品市场存在严重的信息不对称问题。由于监管限制了卖家的信息披露，买家的评论填补了这一信息空白，从而维持了市场需求。我们探讨了这种异质性，并讨论了其理论和实践意义。
