Consumers' Evaluation of Co-Brand Extensions: The Effects of Concept Congruity on the Evaluation of Co-Branded Products, Analyzing the Moderating Role of Task Involvement

Article excerpt


This study extends the branding research, especially brand extension evaluation, and centers on a relatively new, but pervasive, phenomenon of co-branding. The term co-branding implies the use of two or more established brands to name a new product. Previously observed findings in brand extension literature show that a moderately incongruent extension evaluation will be more favorable than it is congruent or extremely incongruent when involvement is high. In this context, the present study examines two issues: (a) to analyze the effects of concept congruity on the evaluation of co-brand extensions (b) and to understand the moderating role of task involvement in evaluation of co-brand extensions. Integrating the knowledge of brand extension evaluation and congruity theory, the study tries to develop a model for evaluating co-brand extension is proposed. This study examines whether or not these findings can be extended to co-branding. So, this study proposes experimental factorial design (2X3) to understand the moderating role of task involvement in three different congruity conditions for co-brand extension evaluation. From the analysis, it found that the results are consistent with the predictions of Mandler's (1982) theory: high evaluation in moderate incongruity than either in high congruity or extreme incongruity.

In recent years, marketing practitioners and academicians concentrated on the study of branding strategies. Consumer product manufacturers are very much interested in co-branding as a means to gain more marketplace exposure, fend off the threat of private label brands, and share expensive promotional costs with a partner (Washburn et al., 2000). The fierce competition among manufacturers and retailers in saturated markets, particularly in consumer durables, led them to adopt co-branding strategy. Co-branding is defined as a branding strategy which is popular in consumer products that pairs two or more branded products (constituent brands) to form a separate and unique product (composite brand) (Park et al., 1996). Broadly defined, co-branding occurs when there is a pairing of at least two partner brands that cooperate in a marketing context, such as advertising, product development, product placement, or distribution (Grossman & Priluck, 1997; Leuthesser, Kohli & Suri, 2003; Kumar, 2005).

Co-branding is an increasingly popular technique marketers use in attempting to transfer the positive associations of the partner (constituent) brands to a newly formed co-brand (composite brand) (Washburn et al., 2000). Co-branded products mainly appear among consumer goods; they are also relevant for durables and services (Helmig et al., 2008). In durables, Compaq® and Mattel® introduced high-tech interactive toys. In non-durables, DANONE® and Motta® introduced "Yolka" ice cream; M&Ms® and Pilsbury® invented a new cookie concept. In services, the HDFC Bank® in India has joined hands with the National Insurance Company (NIC) ® and MasterCard International® to launch a successful Credit / Health Card.

Nowadays, companies are using different variations of co-branding: vertical co-branding, often defined as ingredient branding (Desai & Keller, 2002), in which integrating within one product by producers of different value chain steps (e.g. IBM® & Intel®). Another variation is the composite co-branding refers to use of two renowned brand names joined together in a way that they can collectively offer a distinct product or service that could not be possible individually, usually referred to as co-branding. Four sub- divisions of co branding forms are (a) co branding aimed to develop a separate and unique product or brand, (b) co-branding formed using distinct brands that have complementary use, (c) co-branding aimed for physical product integration, or (d) co-branding that using different brands in combination with market-related products for complementary use or even physical product integration (Washburn et al. …
