To Disclose or Not? Disclosure of Manufacturer Identity in Store Brand Supply Chains With Brand Spillover Effect and Online Reviews
研究了零售商在商店品牌供应链中是否披露制造商身份的策略，发现品牌溢出效应和在线评论会影响披露决策，强溢出效应可能抑制披露。
The increasing prevalence of store brands has attracted both retailers and national manufacturers to participate in store brand operations. However, retailers face a strategic decision regarding whether to disclose the national manufacturer's identity information, especially considering the impacts of the brand spillover effect and online reviews. This research investigates the retailer's disclosure strategy by developing a two-period model and exploring how this decision impacts online review ratings. Our findings illustrate that although the brand spillover effect of disclosing the national manufacturer's identity information can elevate consumers' quality expectations for store brands, the influence of online reviews may diminish or even reverse this benefit. Specifically, a stronger brand spillover effect may adversely affect both parties and thus inhibit the retailer from disclosing such information, which is different from the conventional wisdom. Moreover, we demonstrate that disclosing the national manufacturer's identity is not advantageous for the retailer when the degree of the brand spillover effect is relatively low, consumers are more reference-dependent and rely more on online reviews to formulate quality expectations, and the quality level of the store brand is perceived as moderate. Finally, we consider several extensions, including strategic consumers, distinct pricing power structures, the effect of the national brand's online reviews, asymmetric consumer numbers, and heterogeneous consumer ratings, which either confirm the robustness of our findings or enrich the basic findings.
