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.
