The author presents a conceptual model of brand equity from the perspective of the individual consumer. Customer-based brand equity is defined as the differential effect of brand knowledge on consumer response to the marketing of the brand. A brand is said to have positive (negative) customer-based brand equity when consumers react more (less) favorably to an element of the marketing mix for the brand than they do to the same marketing mix element when it is attributed to a fictitiously named or unnamed version of the product or service. Brand knowledge is conceptualized according to an associative network memory model in terms of two components, brand awareness and brand image (i.e., a set of brand associations). Customer-based brand equity occurs when the consumer is familiar with the brand and holds some favorable, strong, and unique brand associations in memory. Issues in building, measuring, and managing customer-based brand equity are discussed, as well as areas for future research.

Two studies were conducted to obtain insights on how consumers form attitudes toward brand extensions, (i.e., use of an established brand name to enter a new product category). In one study, reactions to 20 brand extension concepts involving six well-known brand names were examined. Attitude toward the extension was higher when (1) there was both a perception of “fit” between the two product classes along one of three dimensions and a perception of high quality for the original brand or (2) the extension was not regarded as too easy to make. A second study examined the effectiveness of different positioning strategies for extensions. The experimental findings show that potentially negative associations can be neutralized more effectively by elaborating on the attributes of the brand extension than by reminding consumers of the positive associations with the original brand.

Branding has emerged as a top management priority in the last decade due to the growing realization that brands are one of the most valuable intangible assets that firms have. Driven in part by this intense industry interest, academic researchers have explored a number of different brand-related topics in recent years, generating scores of papers, articles, research reports, and books. This paper identifies some of the influential work in the branding area, highlighting what has been learned from an academic perspective on important topics such as brand positioning, brand integration, brand-equity measurement, brand growth, and brand management. The paper also outlines some gaps that exist in the research of branding and brand equity and formulates a series of related research questions. Choice modeling implications of the branding concept and the challenges of incorporating main and interaction effects of branding as well as the impact of competition are discussed.brands, brand equity, brand extensions
