Summary: This paper analyzes the impact of currency exchange rate fluctuations on a decentralized global supply chain, proposing two types of currency exchange rate flexibility contracts to mitigate risks for both buyers and suppliers. Results show that optimal order quantities are influenced by exchange rate volatility, and the proposed contracts improve expected profits when payments are in the supplier's currency. The effectiveness of local vendors in mitigating risks associated with overseas orders is also examined.

Summary: This paper explores and demonstrates the potential of blockchain and smart contracts for supply chain finance in the context of cross-border beef supply chains from Australia to China. The study uses the Agents Events Data (AED) process mapping method to improve supply chain processes and traditional SCF models. The findings highlight how blockchain technology and smart contracts can mitigate financial risks and transform credit financing. Additionally, the paper proposes the group buying business model as a promising approach for whole-of-supply-chain finance and showcases the utility of the AED process mapping method for future research.

Summary: This paper examines a supplier-buyer supply chain and investigates how to adapt the menu of contracts under the assumptions of rational buyer behavior and deterministic buyer utility. By integrating multinomial logit model and mixed-integer nonlinear program, a choice-based optimization approach is proposed and qualitative insights are derived.

Summary: The study demonstrates that buyers tend to reject offers in supplier-buyer relationships mainly due to increasing inequality in payoffs, which is termed ratcheting aversion. The buyers' ratcheting aversion limits the supplier's ability to use information revelation in long-term contracts, leading to greater empirical benefits for suppliers.

Summary: The study shows that individual rationality in a two-tier supply chain can lead to supply chain coordination, and inventory regret may result in outcomes different from other reference points. Under competition, inventory regret can lead to either a separating or a pooling equilibrium. This finding differs substantially from the existing literature and has implications for wholesale price contracts and competition dynamics impacting industry service levels.

Summary: This study developed a novel multi-period model to determine multiple ordering replenishment decisions for a product over a short selling season. By considering unsold inventory or unsatisfied demand, the study provides insights into how the ordering decisions of the retailer are affected in specific periods.

Summary: We investigate newsvendor models in which the primary supplier's production is subject to random capacity. To mitigate the supply risk, the retailer contracts with a reliable backup supplier to reserve capacity in advance and acquire the option to use it after delivery from the primary supplier and either before or after demand realization. We identify the conditions under which the use of the backup supplier is beneficial and determine the optimal order and reservation quantities, considering the impact of various model parameters.

Summary: Outsourcing is a popular production mode that benefits both OEMs and CMs. Research shows that there is a threshold outsourcing price beyond which CMs are motivated to overproduce, and in a competitive market, price war is not a wise strategy for CMs.

Summary: This study focuses on the impact of major public health events on the supply chain, as well as the relationship between suppliers and manufacturers, and incentives for suppliers to improve supply reliability through subsidies. The research finds that the optimal order quantity and price of suppliers and manufacturers are affected by the level of reliability.

Summary: This paper examines the optimal financial hedging strategy and sustainable development in four different supply chain structures. It proposes the use of an index-based price contract to transfer risk from manufacturers to downstream retailers and achieve risk-sharing in the supply chain. The study discusses the optimal hedging strategy and the level of product sustainability in monopoly, monopoly with Nash bargaining, retailer competition, and manufacturer competition structures. The findings suggest a positive relationship between the hedge ratio and consumer preference for green products, while it is inversely related to green product research and development costs. Notably, in a manufacturer competition supply chain, slight fluctuations in input commodity prices significantly increase the profits of both manufacturers, but as the fluctuations continue to increase, one manufacturer's profit declines while the other's rises slowly. Furthermore, competition based on product sustainability negatively impacts manufacturers' and retailers' profits and reduces the overall level of sustainability.

Summary: In this paper, a blockchain-based framework for the online sale of pharmaceutical products is proposed. It eliminates intermediaries such as hospitals or pharmacies and utilizes Ethereum smart contracts to monitor interactions, track transactions, and ensure secure payment dispersal. The smart contracts also regulate the interaction between sellers and consumers, monitor IoT container status, and provide full notification to consumers. Special cases such as consumer refunds are handled to ensure the safe delivery of medicines.

Summary: In this study, we investigate a supply chain system consisting of a retailer and a supplier. We examine the threshold problem in contract design and take into account the risk preference of the retailer and the fairness concern of the supplier. The experiment shows that the behavior of the retailer affects the threshold of the optimal contract design, while the behavior of the supplier only affects the optimal wholesale price. These findings suggest that the behavior of retailers and suppliers play a crucial role in the mechanism design of supply chains.

Summary: Companies investing in blockchain technology to enhance supply chain transparency face challenges in collaborations and information sharing. This paper analyzes two ways that blockchain can improve supply chain transparency and explores when and how it should be adopted. The study finds that blockchain increases supply chain profit only when the manufacturer's capacity is large.

Summary: The article discusses the impact of asymmetric information on contracting in a supply chain, emphasizing the importance of retailers signaling superior demand information to suppliers. Asymmetric information can lead to higher capacity in the market and mitigate the double-marginalization problem, ultimately resulting in higher consumer welfare. The study also compares the incentives for retailers to signal demand information versus withhold it, leading to either a separating or pooling equilibrium.

Summary: This paper investigates the economic and environmental implications of biomass commercialization and finds that reducing input price variability or increasing output price variability can increase the economic value of biomass commercialization. However, higher biomass demand or prices may not necessarily lead to a positive environmental impact, as they can increase emissions associated with biomass commercialization.
