Attitude-Based Versus Choice-Behavior-Based Success of Brand Extensions

This study compares the effects of brand extension success drivers across attitude-based and choice-behavior-based measures of extension success within the FMCG sector. Previous research considers different success measures in separate studies, focusing mainly on attitude-based measures. We suggest and empirically test different effects of commonly applied success drivers on one attitude-based and three choice-behavior-based extension success measures. Our findings imply that fit and parent brand strength may not be dominant success drivers in the context of choice-behavior-based success measures. Instead, marketing support for the extension product drives choice-behavior-based brand extension success
