The credibility and consistency of brands are central elements in its position in the minds of con sumers, reducing the uncertainty linked to the buying processes, building associations and solidifying relationships of trust, repeated purchases and brand equity. Retailers started to sell their own brands – Private labels – positioned at low-end segments, based on low price and low quality. Actually we observe the coexistence of PLs with different qualitative levels, based on branding strategies that may include umbrella and/or independent names: private labels are a central strategic issue for all major food retailers. These labels may contribute to increase retailer’s differentiation, exclusivity, associations, loyalty, and, as a consequence, retailer brand equity. Brand equity results from the brand-market interaction, reflected in consumer’s perceptions, preferences and buying behaviors, built from all interactions developed between the consumer and the brand. Recent research tried to conceptualize the brand equity concept to retailers, building and testing “store equity” metrics, has the differential effect of the knowledge about retailers in consumers buying behaviors. Two of the most representative scales about brand equity in retail industry were developed by Arnett, Laverie & Meieres and Pappu & Questerb. This paper is part of an investigation process; focus on measuring Private labels brand equity in the food retailing industry. Actually, it is not clear the Private label real impact in retailers brand equity and if they can be considered a true brand, with exclusive associations and brand equity, autonomous from its “umbrella retailer”.
