Item Equilibrium analysis of dual-channel supply chain under retailer's greening cost information asymmetry(IGI Global journaleditor@igi-global.com, 2020) Rofin, T.M.; Mahanty, B.The purpose of this study is to investigate the impact of information asymmetry of retailer's greening cost on the performance of both the manufacturer and the retailer. The study considers a dual-channel supply chain comprising of a manufacturer and a retailer committed to green operations. The authors have employed sequential game theoretic model to derive the closed form expressions corresponding to the two cases under consideration, that is: (1) complete information and (2) asymmetric information. They have found that the sharing of greening cost information by the retailer can make both the manufacturer and the retailer better off in terms of profit. They have also found that the greening cost information sharing is all the more important when the greening cost efficiency is weak. The study helps retail managers to make a decision on whether to conceal or reveal the greening cost information with the upstream manufacturer. © 2020 IGI Global.Item Impact of wholesale price discrimination by the manufacturer on the profit of supply chain members(Emerald Group Holdings Ltd., 2022) Tm, R.; Mahanty, B.Purpose: The purpose of this paper is to investigate the impact of wholesale price discrimination by a manufacturer in a retailer–e-tailer dual-channel supply chain for different product categories based on their online channel preference. Design/methodology/approach: This paper considers a dual-channel supply chain comprising of a retailer and an e-tailer engaged in competition. Game-theoretic models are developed to model the competition between the retailer and e-tailer and to derive their optimal price, optimal order quantity and optimal profit under (1) equal wholesale price strategy and (2) discriminatory wholesale price strategy. Further, a numerical example was employed to quantify the results and to capture the variation with respect to online channel preference of the product. Findings: It is beneficial for the manufacturer to adopt a discriminatory wholesale price strategy for products having both high online channel preference and low online channel preference. However, equal wholesale price strategy is beneficial for the e-tailer and the retailer in the case of products having high online channel preference and in the case of products having low online channel preference, respectively. Practical implications: The study helps the manufacturers to maximize their profit by adopting the right wholesale price strategy considering the online channel preference of the product when the manufacturers are supplying to heterogeneous retailers. Originality/value: There is scant literature on the wholesale price strategy of the manufacturer considering the heterogeneous downstream retailers. This paper contributes the literature by bridging this gap. In addition, the study establishes a link between the wholesale price strategy and online channel preference of the product. © 2020, Emerald Publishing Limited.
