    Pricing Decisions in a Heterogeneous Dual-Channel Supply Chain Under Lead Time-Sensitive Customer Demand
    (Springer Nature, 2023) Raju, S.; Rofin, T.M.; Saraf, S.
    Internet facilities helped retailers to sell through online channels, and as a result, e-tailers rose into prominence and started competing with retailers. But, the e-commerce industry always confronted the issue of lead delivery time, hindering the growth of many e-tailers. We observed scant literature that studies the impact of delivery lead time on a dual-channel supply chain consisting of retailer and e-tailer. This research paper uses game theory to verify the impact of delivery lead time on pricing decisions of a heterogeneous dual-channel supply chain consisting of the manufacturer, retailer, and e-tailer. We used the Stackelberg game to study the manufacturer’s and downstream partners’ interaction: retailers and e-tailers. A horizontal Nash game was used to model the interaction between the downstream partners. We had analytically modeled how the lead delivery time significantly affects the channel partner’s optimal pricing, sales volume, and profitability. We also did sensitivity analysis to check the influence of the customers’ channel preference coefficient toward a particular channel and its cross-effects on the pricing policies when the customer is also lead time-sensitive. The study revealed that irrespective of large delivery time or next day delivery time, customers’ preference toward a particular channel didn’t affect the manufacturer’s profit, whereas it affected the profit of the retailer and e-tailer. On the other hand, the increase in lead time-sensitivity coefficient severely affected the profit of all the supply chain partners. By analyzing the pricing decisions, we found that both the customer preference and lead time-sensitivity coefficients affected the pricing decisions, but customers’ channel preference coefficient failed to mitigate the effect of lead delivery time. The inputs from this study can be used by practicing managers to develop decision support systems and as an input in multi-agent systems for converting lead time-sensitive supply chains to robust and resilient ones. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    Do wholesale pricing strategies matter during asymmetric disruptions? A game theoretic analysis
    (Emerald Publishing, 2024) Raju, S.; Tm, R.; S, P.K.; Jacob, J.
    Purpose: In most economies, there are rules from the market regulators or government to sell at an equal wholesale price (EWP). But when one upstream channel is facing a negative demand disruption and another positive, EWP can create extra pressure on the disadvantageous supply chain partner, which faces negative disruption. The purpose of this study is to analyse the impact of EWP and the scope of the discriminatory wholesale price (DWP) during disruptions. Design/methodology/approach: For the study, the authors used a dual-channel supply chain consisting of a manufacturer, online retailer (OR) and traditional brick-and-mortar (BM) retailer. Stackelberg game is used to model the interaction between the upstream and downstream channel partners, and the horizontal Nash game to analyse the interaction within downstream channel partners. For modelling asymmetric disruption, the authors took instances from the lock-down and post-lock-down periods of the COVID-19 pandemic, where consumers flow from BM retailer to OR store. Findings: By analysing the disruption period, the authors found that this asymmetric disruption is detrimental to the BM channel, favourable to OR and has no impact on the manufacturer. But with DWP, the authors found that the profit of the BM channel and manufacturer can be increased during disruption. Though the profit of the OR decreased, it was found to be higher than in the pre-disruption period. Under DWP, the consumer surplus increased during disruption, making it favourable for the customers also. Thus, DWP can aid in creating a win-win strategy for all the supply chain partners during asymmetric disruption. Later as an extension to the study, the authors analysed the impact of the consumer transfer factor and found that it plays a crucial role in the optimal decisions of the channel partner during DWP. Originality/value: Very scant literature analyses the intersection of DWP and disruptions. To the best of the authors’ knowledge, this study, for the first time uses DWP as a tool to help the disadvantageous supply chain partner during asymmetric disruptions. The study findings will assist the government, market regulators and manufacturers in revamping the wholesale pricing policies and strategies to help the disadvantageous supply chain partner during asymmetric disruption. © 2023, Emerald Publishing Limited.
