Abstract:
Component sharing may look great in the boardroom but not in the showroom. Indeed, savings on research and development and production costs could be offset by a plunge in customer brand attractiveness. The central objective of this paper is to investigate consumer and market responses toward component sharing between brands. More specifically, by combining experimental with econometric studies, this paper investigates the impact of component sharing on customer evaluation of luxury, volume, and economy brands offered in a car manufacturer’s vertical product line. An experimental study in which component sharing between automotive brands was made explicit aimed to understand the impact of brand combinations and type of sourcing on the evaluations of the two brands sharing components. This experimental study shows that the evaluation of luxury brands sharing with a volume brand suffers more than when a volume brand shares components with an economy brand. This experimental study was executed for two different brand combinations including one luxury, one volume, and one economy brand: (1) Audi, Volkswagen, and Skoda; and (2) Lexus, Toyota, and Suzuki. The evaluation of an economy brand benefits more from sharing with a volume brand than a volume brand suffers from sharing with an economy brand. The magnitude of these effects depends on several factors, such as component type, the source of the component sharing, and the salience of component sharing to the consumers. One important limitation of the experiment is that component sharing is made rather salient, and no behavioral effects of component sharing are studied. Therefore, a second was executed in which market share data on brands of the Volkwagen company (i.e., Audi, Volkswagen, Seat, and Skoda) were collected, while also data on the component-sharing practices between these brands were gathered. A market share model was estimated in which market shares of the four studied brands were explained by component-sharing practices and some control variables (i.e., price, model changes) in an exploratory fashion. The explorative examination of market share effects confirms that luxury brands may suffer, while economy brands may benefit from component sharing. In sum, this research suggests that component sharing between brands has negative effects for the higher-end and positive effects for the lower-end brand. However, it also shows that sourcing matters. This study is considered as the first study investigating the phenomenon of component sharing, and it points to multiple future research issues, such as studying this phenomenon in other markets.
