In order to explore the impact mechanism of carbon information disclosure behavior of manufacturers and remanufacturers considering extended producer responsibility (EPR) and low-carbon preference on corporate profits of outsourced remanufacturing closed-loop supply chain, this study constructs a two-level supply chain composed of manufacturers and remanufacturers. This paper integrates corporate carbon disclosure with recycling and remanufacturing activities and develop four models according to whether enterprises fulfill EPR information disclosure responsibilities. This study analyzes the equilibrium strategies of manufacturers and remanufacturers in four modes through Stackelberg game and finds that: Firstly, the implementation of EPR is more conducive to enhancing the overall profitability of enterprises compared to a scenario without EPR. Concurrently, enterprises will focus more on consumer low-carbon preferences and market dynamics when implementing EPR policies, thereby striving to enhance their competitive edge. Secondly, manufacturers and remanufacturers should collaborate actively in carbon information disclosure activities to achieve coordinated development between upstream and downstream enterprises. Such collaboration is beneficial for increasing the product recovery rate of remanufacturers. Lastly, social welfare is maximized under a full EPR scenario. The state of social welfare varies with changes in cost subsidy disclosure and consumer low-carbon preferences. Notably, the disclosure efforts of remanufacturers contribute more significantly to social welfare than those of manufacturers.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 71-84"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fill this gap, this study considers a monopolistic firm selling products that require consumers’ post-processing assembly for effective use. Two distinct consumer segments exist in the market, including professional and amateur consumers, each with unique product needs and processing capabilities. Furthermore, this study analyses two strategies in which the BOAS channel is introduced or not. We build a game-theoretic model to analyse the impact of the BOAS channel on firms’ optimal decisions, profits and consumer surplus. The findings demonstrate that implementing the BOAS channel in some circumstances will reduce the total demand for the product, although it may increase demand from professional or amateur consumers independently. Moreover, introducing the BOAS channel has various effects on the firm and consumer surplus depending on some critical parameters, including the distribution of consumer types and product handling costs. Particularly, a larger proportion of professional consumers can incentivise firms to adopt the BOAS channel, while higher handling or travelling costs may lead firms to avoid its use. In terms of consumer surplus, although the introduction of BOAS channels appears to enhance amateur consumers’ experience, it may hurt the total consumer surplus in some cases. Finally, we also discussed the impact of BOAS on sustainable operations and found that by centralising the final assembly or customisation of products, the introduction of the BOAS channel can optimise the use of resources, reduce material wastage and improve efficiency. This study significantly contributes to the existing body of knowledge by elucidating the nuanced effects of BOAS on firm strategies and sustainability, providing actionable insights for practitioners navigating the complex omni-channel landscape.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 47-56"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143815163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The additional demand generated from the third-party platform may impose greater capital pressure on the retailer. In response, some third-party platforms offer financing service to capital-constrained retailers sell on them. Therefore, we establish a Stackelberg game-theoretic model where a manufacturer sells green products to a capital-constrained retailer which has an offline channel and a third-party platform channel. Two financing strategies are considered: bank credit financing (BF) and third-party platform credit financing (TF). The manufacturer as the leader first determines the wholesale price and the lender (bank or the third-party platform) then sets an interest rate. The retailer finally decides the retail price. Our theoretical analysis shows that for the manufacturer, retailer and third-party platform, TF strategy is better than BF strategy. That is, TF strategy is a win-win strategy. Specifically, under the TF strategy, the retail price or the interest rate are lower compared to the BF strategy, while the wholesale price under TF is higher. Additionally, our finding shows that the revenue sharing rate has no impact on the manufacturer’s wholesale price decision under TF strategy, whereas under the BF strategy, the wholesale price decreases as the revenue sharing rate increases. We also find that the retail price increases with the revenue sharing rate under BF, but decreases under TF strategy.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 153-169"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
