Do brands of a feather flock together? Some exploratory findings on the role of individual brands in brand constellation choice

Abstract

The common view of brand choice in consumer marketing is that brands compete against each other within a specified product category. For example, different coffee brands are compared and evaluated by consumers and the most preferred brand is selected. Is this the only adequate way of demonstrating how consumers make brand choices?This thesis challenges the common view on brand choice and brand choice determinants in consumer markets on several accounts. First, brand choice is made in goal-derived categories (e.g., foods to eat while on a diet), and research on goal-derived categories and consumption goals suggests that consumers often choose between brands from different product categories. For example, a consumer may choose between brands of coffee, tea, and soft drinks to fulfill a consumption goal. Second, there is the question of complementarity. Are brands always chosen one by one? We argue in this thesis that consumers often choose brand constellations from complementary product categories in goal-derived categories (e.g., hamburgers and soft drinks when on a short lunch break). The thesis consists of four articles based on empirical studies. The articles cover single-brand choice and brand constellation choice in goal-derived categories, and the use of goal-derived categories by marketing practitioners. The general conclusion is that consumers evaluate more aspects than just brand-related ones when they choose brands in goal-derived categories. Product category associations (i.e., how typical a product category is perceived in a goal-derived category) are a more important determinant of brand (constellation) choice than brand associations. Also, in brand constellation choice, complementarity (i.e., perceived fit between brands) is more strongly related to brand choice than attitude towards individual brands.
