Sources of Brand Decline Public

Abstract

Sources of Brand Decline
By: Adina N. Barbulescu
Brands are important assets for companies and contribute significantly to
company revenues. Firms, however, need to steadily preserve and nurture brands in order
to continue to appropriate a brand's value.Brand decline refers to the weakening of the brand in
consumers' minds in terms of consumer attitudes and intentions to purchase a brand.
While a number of factors may lead to a brand's decline, I focus on two sets of factors.
The first factor relates to consumers' knowledge of the brand and its structure. The
second factor revolves around consumers' experiences with a brand over time. I
investigate these two issues in two essays that comprise the dissertation.
In Essay 1, I argue that different knowledge structures consumers have for brands leads
them to be differentially vulnerable to competitor actions, resulting in greater or lower
change in brand attitude. Consumers' knowledge of brands is comprised of brand
associations (or nodes) and potential causal linkages among these nodes. I argue that in
the absence of causal linkages, consumers are more likely to negatively change their
attitude towards the brand following a competitor challenge on one of the brand's nodes.
A brand need not decline only under the pressure of competitors. In Essay 2, I argue the
pattern of consumers' sequence of experiences with a brand can lower the likelihood of
brand repurchase. A brand becomes increasingly weak when consumers expect low levels
of brand performance in the future (i.e., point expectation) or considerable variability in
the level of these performances (i.e., range expectation) (Rust et al. 1999).
I extend this stream of literature and argue a brand's decline, measured as low likelihood
of brand repurchase, is also determined by the distribution of consumers' range
expectation above and below the point expectation of brand performance.
