内容简介：
This paper provides empirical evidence on the effect of the September 2015 Volkswagen diesel emissions scandal on the stock prices of publicly traded firms in the global automotive ecosystem. We focus on both the supply chain partners of VW – tier-1 suppliers; tier-2 suppliers; and business customers – and three groups of firms that are not VW supply chain partners – other motor vehicle manufacturers; parts manufacturers not identified as VW suppliers; and wholesalers, retailers, and rental agencies not identified as VW customers. We find that tier-1 suppliers of direct material to VW suffered a mean stock price reaction of ─2.69% in the week following the scandal, but this effect varied by region. European suppliers were the most impacted with a mean stock price reaction of ‒5.52%. Suppliers with larger revenue dependence on VW experienced greater negative stock price reactions, as did suppliers of components for engines and/or emissions systems. Non-VW parts manufacturers experienced a positive effect. We find a mean stock price reaction of ─5.28% to VW’s European customers, but no significant effects for non-VW customers. European motor vehicle manufacturers experienced a mean stock price reaction of ‒7.60%. Our results suggest that firms should not just focus on selecting and monitoring responsible suppliers but also apply some of the same principles to developing responsible customers. Our work also has implications for industry groups, regulators, and legal systems, entities that have the resources and capabilities to effectively monitor large firms to reduce illegal or irresponsible behavior such as the VW scandal.
本文提供了关于2015年9月大众柴油排放丑闻对全球汽车生态系统中上市公司股价影响的实证证据。我们聚焦于大众的供应链合作伙伴：一级供应商、二级供应商、商业客户、三组非大众的供应链合作伙伴公司以及其他汽车制造商。但零部件制造商未被认定为大众的供应商，批发商、零售商和租赁机构未被认定为大众客户。我们发现，在丑闻发生后的一周内，向大众提供材料的一级供应商的平均股价反应是-2.69%，但这种影响因地区而异。欧洲供应商受到的影响最大，平均股价反应为-5.52%。对于收入高度依赖大众汽车的供应商则经历了更大的负面股价反应，发动机和排放系统组件的供应商也是如此，但非大众零部件制造商则受到了正向影响。大众欧洲客户的平均股价反应为-5.28%，但对非大众客户没有显著影响。欧洲汽车制造商的平均股价反应为-7.60%。我们的结果表明，企业不应只专注于选择和监控负责人的供应商，而且还应将部分标准原则用于开发客户。我们的工作还对行业团体、监管机构和法律体系产生了影响，这些实体有资源和能力有效监控大型企业，以减少非法或不负责任的行为（如大众丑闻）。
