This paper aims to examine the potential for adjacent brands to influence sales of a focal brand. Specifically, this paper examines whether the type of adjacent brand (market leader or non-market leader competitor) and its promotion (featuring or discounting) have an effect on sales of a focal product.


Store-level scanner data supplemented with in-store audits are used.


It is demonstrated that adjacent brands and their specific marketing activities influence focal brand sales in specific ways, and that market leaders have a disproportionate and different effect than other competitors on the sales of adjacent brands.


Recent marketing research has suggested that brand activities such as featuring and discounting and in-store environmental stimuli such as shelf allocation and displays can have an important effect on category and individual brand sales. Prior work in this area, however, has not explicitly considered the potential influence of relative shelf positions (i.e. adjacencies) on brand and category sales.



This research was supported by Auburn University’s Department of Marketing Summer Research Grant. The authors thank Craig Stacey and Dr Douglas Bowman for their help in securing access to the data examined in this paper.
