The impact of branding strategies on horizontal and downward line extension of luxury brands: A cross-national study

Purpose: The purpose of this paper is to empirically assess the impact of branding strategies on horizontal and downward line extensions of French luxury brands in a cross-national context (France vs USA). Design/methodology/approach: This study is based on a two line extensions (horizontal/downward) × three branding strategies (direct brand/sub-brand/standalone brand) x two country (France/USA) between-subjects ANOVA design. Findings: The study shows that the subtyping effect created by a sub-branded luxury downward line extension tends to be rated similarly to a direct branded extension which oppose previous beliefs put forward in non-luxury settings. In contrast, a new independent/standalone extension fully uses the subtyping effect which helps attenuate this risk related to luxury downward stretches. The study also found that the effect of gender in cross-national settings must always be taken into consideration as significant variations occur in the process. Research limitations/implications: The study covers two countries but should be replicated in other cross-national contexts. Practical implications: This study helps marketing managers of luxury brands make a better decision when it comes to launching vertical line extensions (upscale/downward) by carefully using types of branding strategies and relevant communications whether women and/or men are targeted in cross-national contexts. Originality/value: This study breaks new ground in the international luxury literature by providing key theoretical and managerial insights in terms of launching new downward line extensions with the proper use of branding strategies when targeting specific genders.
