Directions for Future Research
For marketing academics, our study challenges the assumption of the stability of channel price leadership (which typically sees manufacturers as the price leaders), which has been made in previous theoretical or empirical research on SB-related issues. In addition, our empirical findings suggest the retailer often engages in different leader–follower relationships across multiple NB manufacturers within the category, both before and after SB introductions. This is in contrast to the typical theoretical channel models assuming a uniform leadership scenario across competing manufacturers, and points to the need for more rigorous studies on asymmetric price leadership structures in future research. We hope some of those future studies will seek deeper theoretical insights into the key determinants of the retailer’s strategic choices regarding channel price leadership after SB introductions. Our study focuses on reporting an interesting empirical phenomenon with some plausible explanations, but falls short of providing clear theoretical understanding of the underlying factors that need to be investigated in future studies. Our empirical analysis is also limited by the data including four product categories from one grocery chain. Expanding the analysis to other product categories and other retailers will enhance the generalizability of the results. In particular, our analysis was limited to the situation where SB was introduced as the lowest-priced brand in the category. Given the growing trend of increasing SB quality and marketing a line of multiple SBs within a product category, the investigation of the channel price leadership issue within a model reflecting such realities will be interesting. In addition, simultaneous consideration of the retailer’s strategic decisions over SB positioning and channel price leadership might lead to new strategic recommendations based upon deeper understanding of the interaction between these two topics that have been studied in separation.
