“…These studies have generated important insights into a number of areas of the process of consumers' attitudes towards and evaluations of brand extensions, e.g., brand and category-level fit (Boush et al, 1987;Broniarczyk and Alba, 1994;Bhat and Reddy, 2001;Park et al, 1991;Lau and Phau, 2007;Milberg et al, 2013), the effect of prior knowledge of the extension category or the brand (Boush and Loken, 1991;Bottomley and Holden, 2001), forward and reciprocal spillover effects between parent and extension (Jacobson and Lane, 1997;Balachander and Ghose, 2003), consumer motivation and expertise (Broniarczyk and Alba, 1994), advertising and marketing strategy (Balanchander and Ghose, 2003;Dens and De Pelsmacker, 2010) and purchase intention (Lane, 2000;Bhat and Reddy, 2001). As pointed out by Czellar (2003), the vast majority of existing research focuses thus on consumer characteristics, predominantly rooted in cognitive psychology (e.g., Aaker and Keller, 1990;Park et al, 1991;Broniarczyk and Alba, 1994;Bhat and Reddy, 2001;Monga and John, 2010), and pays little attention to other factors such as consumer heterogeneity, competitor and distributor activity.…”
