However, it is unclear how supply chain transactions (ride price) and yields are affected due to a commission fee on ride-sharing platforms. To better understand, this study explores the impact of the service provider's price-setting (Model S) and service enabler's price-setting (Model E) power mechanism on supply chain profit under the influence of price competition in a sharing economy. We consider duopoly supply chains, wherein in one supply chain, a service provider delivers service through a service enabler, and in another, service providers offer direct customer service. Mathematical models are developed to analyze the difference in price-setting power mechanism effect, considering marketing efforts under different competitive scenarios. Results show that the supply chain profit is highest when the service provider sets the transaction price in Model S. Furthermore, when the commission fee exceeds a certain threshold (0.5), the total profit in Model E increases, but in Model S it decreases. In ride-sharing platforms, the service provider loses with a rise in commission fees, while the service enabler profits from it. The study contributes to the growing interest in the intricacies of sharing economy businesses.

To the best of the author’s knowledge, there is no study to discuss the impact of customer-centric retailing on total supply chain profit under price competition between organized and unorganized retailers. Design/methodology/approach This paper considers a supply chain comprising of organized and unorganized retailers and a single manufacturer. This paper proposes three mathematical models considering a customer-centric approach in a competitive environment. Stackelberg game is used to examine how members of the chain interact, and Nash equilibrium was used to find optimal strategies for players under different customer-centric approaches. Findings The results show that the total supply chain profit is higher when both organized and unorganized retailers use a customer-centric approach independently instead of collaborating pro...

In order to curb the sharp rise in pollution levels in the country, it has become imperative for the government to implement these stringent guidelines. Thus, this study evaluates the switching intention (SI) of Indian consumers from Bharat Stage 4 (BS4) to BS6 compliant vehicles using the theory of planned behavior (TPB). For that, the study proposes a conceptual model that integrates the ruling factors of TPB, namely, subjective norms, perceived behavioural control, and attitude with two additional factors price and green benefits to assess the SI of consumers. Then, the model is tested against the validity and reliability using confirmatory factor analysis, and hypotheses are tested using structural model analysis. An online survey was conducted among 513 Indian consumers who own BS4 or older compliant vehicles to collect data for this analysis. The findings indicate that Indian consumers' SI is significantly and positively impacted by all five constructs: subjective norms, perceived behavioral control, price, attitude, and green benefits. Furthermore, multi-group analysis is performed to check the impact of socio-demographic characteristics such as gender and age on SI.

Renewable energy helps to reduce emissions if the industry supply chain is used optimally. Further, there is little understanding of how renewable energy implementation cost and stock dependence simultaneously impact supply chain (SC) profit. Thus, we propose a duopoly sustainable supply chain considering renewable implementation and stock-dependence demand under uncertain environments. A mathematical model is developed for a sustainable supply chain under three scenarios: (i) Renewable energy effort by manufacturer and cost-shared by the retailer (Model M) (ii) Renewable energy effort by retailer and cost-shared by the manufacturer (Model R), and (iii) Renewable energy effort by both retailer and manufacturer and cost-shared by the manufacturer and retailer (Model C). Nash equilibrium was used to find optimal strategies for players under different integrated channels. The result finds t...

Omnichannel and bundling settings can help firms improve operational efficiency and lower returns costs. However, no studies have been conducted on omnichannel supply chains considering bundling strategies. The purpose of this study is to examine the comparison between test-in-store-and-buy-online (TSBO) and online retail, comparing manufacturers’ bundling with retailers’ bundling. Design/methodology/approach The supply chain discussed here consists of two competitive manufacturers and one retailer. The retailer sells both manufacturers' products online and displays one manufacturer's product in a showroom who bears the display cost. Stackelberg game theory is used to develop mathematical models that help manufacturers and retailers make the most effective decisions. Here, the manufacturer is the Stackelberg leader, while the retailer is the follower. Using the ba...

Sustainability is of particular importance to tour operators because their products are dependent on local operators, including accommodations, transportation, and activities. When a tour operator uses a local operator as a channel for reaching tourists, the ecotourism strategies takes on an additional dimension: which party will perform the ecotourism effort to end tourists. Cost sharing arrangement expands the option by decoupling the execution of ecotourism strategies from its funding. However, tourism is typically described as various supply chains in research, yet little is known about their ecotourism effort when considering cost-sharing. We develop a mathematical model for a tourism supply chain under two scenarios: (i) ecotourism effort without cost-sharing and (ii) ecotourism effort with cost-sharing. Using game theoretic models, we compare equilibrium outcomes under cost sharing and without cost sharing scenarios. The results show that the tourism supply chain generate more profit in without cost-sharing compare to with cost-sharing. The results of our study also indicate that the total profit is higher when the local operator performs the sustainability and a portion of the cost of the ecotourism effort is shared by the tour operator. The economic benefit to the tour operator and local operator is higher when both players dedicate their effort to ecotourism individually. A numerical example is provided to further illustrate our numerical analytical finding and gain more managerial insights.

Moreover, the act of giving incentives to retailers by the manufacturer is also quite prevalent in the present business environment. These incentives are offered to promote the sales of products of a manufacturer. Therefore, this paper examines the optimal decisions for a dual-retailer closed-loop supply chain (CLSC) in which the manufacturer bestows the credit period to the one retailer (a firm that possesses shallow market penetration and has a higher insistence on the usage of the capital venture), and cash discount to the next retailer (a firm that occupies the market to a greater extent and receives lower thrust on the usage of invested capital) under a non-coordinated system and coordinated systems. This study proposes the mathematical model to determine the optimal decisions of the manufacturer in terms of credit period and...

In competitive practice, both price- and service-sensitive demand play a significant role for tourists in selecting a tour package. In this paper, the authors discuss a case in which two tour operators compete on price and service to offer tour packages and serve the customers through a common local operator. The authors develop a mathematical model for a tourism supply chain under three scenarios: (i) a decentralized scenario, (ii) an integrated-channel scenario, and (iii) a global scenario. The results show that the tourism supply chain generates more profit when there is competition compared with when there is no competition. Furthermore, the results show that coordination among supply chain members with surplus sharing contracts improves the overall tourism supply chain profit compared with the decentralized scenario.

Most TSC studies, to date, assumed the market demand to be influenced only by tour price under price competitive environment, not considering the effect of advertising investment. In order to address this problem, two models are established considering decentralized channels: tour operator Stackelberg (TS) and local operator Stackelberg (LS). We analytically show TS model to provide better results than LS model and advertising to strongly influence the channel members’ pricing strategies and profit. Then we generalized the solution considering multiple operators under price competition. We studied two coordination mechanisms, cooperative advertising and two-part tariff, and found the two-part tariff provides better mechanism for improving the profit in LS model compared to cooperative advertisement.

Both the firms are competing on price and service to sell their substitutable products through a common retailer, and provide service directly to the end customers. Mathematical models are developed here for four different remanufacturing configurations and derive the equilibrium decision and profit under each of the configurations. Further, identify the situation under which the manufacturers can select direct system and integrated system compared to the global system. One of the key findings is that, when demand variation increases, direct system provides a better result in terms of channel profit compared to other channel configurations. Quantity discount with return contract mechanism is developed to coordinate the decentralized system. The model is demonstrated though a numerical study. An extensive sensitivity analysis is performed to examine the impact of different parameters on the model output to draw managerial insights.

Till date, no research has been carried out on consumers' intention towards returning the used products. The aim of this research is to develop a theoretical model to examine the intention and perception of consumers' for retuning the used products and to explore the various cues that consumers use for returning the End-of-use and End-of-life products. The model is examined through an empirical study and the developed hypotheses are tested by conducting a survey among the college graduated students and others (job holder and non-job holder) for specified electronics products. Finally, the extent of return intention index of the consumers is computed using the structural equation modeling. The results revealed that return intention is positively influenced by the perceived benefit and social awareness, whereas negatively influenced by the perceived risk.

The supply chain comprises of two manufacturers who compete for selling their new product as well as for collection of the used-products for remanufacturing through a common retailer. To analyze the situation, mathematical models are developed here for three different cases (i) Non-cooperative system (ii) Channel-cooperative system and (iii) Global-cooperative system. For each of the cases, we have characterized optimal wholesale price and fraction of collection of used product. To draw more managerial insights, we also examine the sensitivity of various parameters such as market size, acquisition cost and transfer price on total channel profit. A numerical study is carried out to illustrate the model, and the results reveal that global-cooperative system is the best among all the three cases considered here. Weighted Shapely Value mechanism is used for sharing of surplus generated in the system due to channel-cooperation .

In this paper, we considered that return demand function is uncertain and sensitive to the acquisition price and the availability of used products in the market. A mathematical model was developed to investigate the impact of the availability of return items in the market on acquisition price management. Here, three different methods of collection of return items from the market are considered: direct method, indirect method and coordinated method. A numerical study was conducted to illustrate the mathematical model, and an extensive sensitivity analysis was carried out for the three different methods of collection to examine the impact of market size and the available dependency factor on acquisition price and the channel profit. The results show that the total channel profit increases when the acquisition price increases for the direct method of collection. Furthermore, the results reveal that the total channel profit increases when the market size increases for the coordinated method of collection compared with the other two methods of collection.
