The purpose of this paper is to examine the effect of country of origin (COO) information as an important/salient categorical attribute on choice context effects. Specifically, this research examines whether the introduction of a unique COO in the choice set will have a differential influence on context effects depending on the relative position of the third option (the asymmetrically dominated option vs the extreme option).
Five experiments were conducted in this research. Study 1 had a 2 (set size: two-option core set vs three-option asymmetric dominance set)×2 (competitor’s COO: common vs unique) between-subjects design. Study 2 had a 2 (set size: two-option core set vs three-option extreme option set)×2 (competitor’s COO: common vs unique) between-subjects design. To address the robustness of the effects, Studies 3-5 replicated the results of Studies 1 and 2. The data were analyzed by χ2 tests and logistic regression analyses.
The current research demonstrates that the attraction effect is attenuated by the introduction of a unique COO information in the competing option, whereas the tendency to prefer a middle option is not significantly affected.
The present research adds to the current understanding and the practical relevance of COO effects and context effects in marketing by examining the impact of COO as an important/salient categorical attribute on context effects.
