Brand equity is a concept that emphasizes the importance of branding in marketing strategies and is a key indicator of brand strength and value.
Brand equity, in marketing, is the worth of a brand in and of itself — i.e., the social value of a well-known brand name. The owner of a well-known brand name can generate more revenue simply from brand recognition, as consumers perceive the products of well-known brands as better than those of lesser-known brands.
In the research literature, brand equity has been studied from two different perspectives: cognitive psychology and information economics. According to cognitive psychology, brand equity lies in consumer's awareness of brand features and associations, which drive attribute perceptions. According to information economics, a strong brand name works as a credible signal of product quality for imperfectly informed buyers and generates price premiums as a form of return to branding investments. It has been empirically demonstrated that brand equity plays an important role in the determination of price structure and, in particular, firms are able to charge price premiums that derive from brand equity after controlling for observed product differentiation.
