In the article, Luc Wathieu of the Harvard Business School, and his colleagues, note that "higher quality, higher regular price brands are less likely to be chosen after posting and retracting a price discount, whereas lower quality, lower regular price brands will continue to divert buyers away from higher quality brands after the discount is retracted with no detrimental impact on their own initial customer base."
The authors explain that previous research has not investigated the idea of different quality brands and effect of discounts on subsequent consumer behavior. The research summarized reflects four experiments that sought to explore this issue more deeply.
In addition to the general findings regarding the disparity of quality with regard to discount, the authors also note other applications for the research. "Beyond highlighting the detrimental effects of promotions on higher quality brands, this research (perhaps more interestingly) suggests that temporary discounts can be used by cheaper brands to permanently divert consumers away from high-end competitors," the article states. "An implication of these findings is that retailers who seek to create an enduring advantage for their store brands might be best advised to encourage in-store discounting by national brands."
