Abstract
ABSTRACT Different information disclosure formats have been implemented to solve the severe product-return issue in platform retail. Considering the significant impact of channel structure choice on the information disclosure strategy, we explore their interaction by investigating the role of product returns. A multistage sequential game model is built in a supply chain comprising a platform and supplier. First, we derive the equilibrium pricing decisions in the short term and examine the role of product returns. Second, we study the optimal information disclosure strategy and channel structure choice in the long term. We also investigate the impact of the optimal strategy on the entire supply chain’s profits and consumer surplus. The following results were obtained: (1) Under the no information disclosure strategy, the presence of product returns weakens the impact of double marginalization in the wholesale model. Therefore, the information disclosure strategy improves product returns, but aggravates the double marginalization effect. (2) Information disclosure benefits the consumer and supply-chain members who disclose information, but may hurt the entire supply chain due to its negative spillover effect on other supply-chain members. (3) The optimal channel structure choice for the platform depends on the trade-off between these two effects of the information disclosure strategy on product returns. Therefore, platforms and suppliers should reexamine their attitudes toward product returns and be aware that more information is not always better, because of the impact of product returns.
