Summary: This paper develops a closed-loop supply chain with a manufacturer and a retailer, which adopts either a retail channel or a dual-channel sales mode for product selling and a manufacturer, retailer, or hybrid recycling mode for used product collection. Six game theory models are formulated to determine the optimal pricing and recycling rate decisions based on different sales and recycling modes. The paper explores the strategies for selecting optimal sales and recycling modes through model comparisons and numerical analysis. The findings reveal that customers, the environment, and the manufacturer generally prefer the dual-channel sales mode. However, the retailer's preference for the dual-channel (retail channel) sales mode depends on the discount coefficient of demand. Additionally, customers, the environment, and the manufacturer favor the hybrid (retailer) recycling mode when the competition intensity for recycling is relatively low (high). However, the retailer's choice of recycling mode varies depending on the type of supply chain.

Summary: This study investigates the impact of online and offline dual recycling channels in a closed-loop supply chain, and how government subsidies affect pricing decisions and recycling mode selection of channel members. Findings show that in dual recycling modes, remanufacturers can maximize profits by setting appropriate recycling and transfer prices, while collectors prefer single offline recycling due to competitive threats from online recycling. The relationship between collection quantities in the three modes depends on consumer preferences for the online recycling channel. Additionally, government subsidies play a positive role in promoting recycling and remanufacturing willingness of remanufacturers and collectors.

Summary: This paper investigates the dynamic pricing strategy of a firm for successive-generation products under the conditions of limited trade-in duration and strategic customers. It explores the effect of limited trade-in duration on the choice behavior of myopic and strategic customers, as well as the optimal dynamic pricing and trade-in strategy of the firm. The authors develop a two-period game-theoretic analytical model and find that extending the limited trade-in duration and implementing a dynamic pricing strategy is better for profit maximization. The results also suggest using a dual rollover strategy instead of a single rollover one.

Summary: Based on previous research, this study investigated the effectiveness of two blood donation incentives-eligibility for free blood transfusions and improving individual credit scores-and their underlying psychological mechanisms. Four studies were conducted to explore the relationship between incentives and blood donation intention. The results showed that eligibility for free blood transfusions was more effective, mediated by perceived attractiveness, compared to improving individual credit scores, which had a lower effectiveness due to the mediating effect of perceived threat to freedom. With the moderating variable of involvement, there was no difference between the two incentives in the high-involvement group due to weakened mediating effects of perceived threat to freedom and perceived attractiveness. This study establishes two effect paths explaining the effectiveness of incentives on blood donation intention.

Summary: This study examines the impact of value-insured strategy provided by crowdsourced delivery platforms (CDPs) on the decisions of the platforms and the participation behaviors of senders and couriers. The research finds that introducing a value-insured strategy benefits the CDP only when the courier's sensitivity to the declared value is adequate. The optimal insurance scheme for the CDP depends on the average declared value, with the reinsurance scheme producing the highest profit when the value is below a certain threshold, and the fixed-fee scheme when it is above the threshold. Offering a value-insured service does not always increase consumer surplus, labor welfare, and social welfare, and may not necessarily benefit the CDP.

Summary: Trade-in promotions are recognized as effective strategies in retail operations to boost sales. This study examines the impact of brand loyalty on exclusive and nonexclusive trade-in programs and finds that an exclusive trade-in program effectively retains consumers when brand loyalty is weak, while a nonexclusive trade-in program is more likely to attract competitors' consumers. An exclusive trade-in program is the dominant strategy for both firms compared to no trade-in, but a nonexclusive program is better when brand loyalty is strong.
