번들제품이 디커플링과 번들된 부제품 평가에 미치는 영향: 심적계좌 존재성과 모호성의 조절효과를 중심으로

This paper focused on the impacts of product bundle type which is utilized to cause decoupling and enhance the bundled sub-product evaluation. It was hypothesized that mixed product bundle would improve decoupling more than same product bundle. And it also examined the moderating effects of the characteristics of mental account such as existence and ambiguity between the type of product bundle and bundled sub-product evaluation. We adopted a scenariobased quasi-experiment to compare 6 types of advertisement in terms of product bundle type. After exposed one of 6 scenarios, participants were asked to answer questions to measure the influence of product bundle on decoupling and bundled sub-product evaluation. Out of 350 participants, 320 valid questionnaires were collected and then analyzed. The results of the study are as follows. Mixed product bundle has more positive effect on decoupling of mental account than same product bundle. And existence and ambiguity as the characteristics of mental account variables showed the moderating effects between the product bundle type and bundled sub-product evaluation. Specifically, firstly, when mental account of sub-product exists, mixed-leader bundle has more positive effect on the sub-product evaluation than mixed- joint bundle. And when mental account of sub-product does not exist, mixed-joint bundle has more positive effect on the sub-product evaluation than mixed-leader bundle. Secondly, when mental account of sub-product is an ambiguous situation, mixed-joint bundle has more positive effect on the sub-product evaluation than mixed-leader bundle. And mental account of sub-product is not an ambiguous situation, mixed-leader bundle has more positive effect on the sub-product evaluation than mixed-joint bundle. Finally, the limitations and future research directions base on this study results are discussed and suggested
