Summary: This study examines the contract strategies for two competing supply chains selling substitutable products under demand uncertainty. It identifies the conditions under which each type of contract should be offered in a competitive market and which type of contract is preferred by manufacturers only or by both manufacturers and retailers. The findings suggest that wholesale price contracts may be a better choice to mitigate chain-to-chain competition, especially when there is moderate price competition and significant demand variation.

Summary: This paper proposed a flexible return strategy under demand uncertainty, in which the retailer has the power to choose return quantity independently through selective buyback contracts, adjusting profit distribution within the supply chain. The numerical studies showed that this strategy can effectively coordinate a supply chain with one retailer and one supplier, giving the retailer more decision-making power and providing risk compensation to the supplier through put options.

Summary: This paper focuses on a buyback contract in a two-echelon supply chain, investigating how yield uncertainty and bargaining power affect the performance of the contract. The study suggests that higher bargaining power and control over uncertain yield lead to better coordination with the buyback contract. If the seller cannot control yield uncertainty, a Buy-Back-Revenue-Sharing contract may be necessary for coordination.

Summary: This study examines the impact of return policies on a supply chain with supplier competition between a retailer and manufacturers. It concludes that in equilibrium, manufacturers always offer full-credit return policies to the retailer, despite the theoretical argument against it. The presence of return policies can intensify competition among manufacturers, potentially harming them while benefiting the retailer. Additionally, an increase in the retailer's ordering capacity benefits the manufacturers and the supply chain overall, although it may lead to decreased profits for the retailer.

Summary: The study focuses on the competition and cooperation between OEM and IR in the remanufacturing market, analyzing their profit-driven buyback strategies. The findings suggest that the low-pricing strategy is a profitable buyback decision for OEM, while the incentive offer is a profitable buyback decision for IR.

Summary: We examine the impact of uncertainty of uncertainty (UOU) on corporate accounting conservatism and find a positive association. Mechanism analysis reveals that under UOU, creditors' demand for real information drives an increase in accounting conservatism. Further analysis shows that the effect of UOU is more pronounced in non-SOEs and firms with weak external monitoring mechanisms. Our study highlights the significant role of contract demand in corporate governance under uncertainty about levels of uncertainty.

Summary: This study examines buyback contracts in a dyadic supply chain and focuses on optimal buyback contracts under linear additive demand. The results show that the supplier's preference for buyback contracts depends on the unit production cost and the dispersion of demand uncertainty, and the optimal buyback rate and profit allocation within the supply chain are also affected by demand uncertainty.

Summary: The study evaluated the effects of a volume-price contract initiative on pharmaceutical prices in Xiangyang, China. Results showed that the initiative led to a significant decrease in the procurement price of cardiovascular medicines in Xiangyang compared to Yichang. The top 100 domestic suppliers were highly responsive to the initiative, indicating the potential for reducing pharmaceutical prices.

Summary: This study analyses the inventory management strategy for perishables using the (s, S) continuous review inventory policy and the zero-leadtime assumption. A buyback contract is provided and the sales cycle is illustrated using the Markov renewal approach. Closed-form formulas for long-run profit rates are derived and the global optimal (s, S) policy is solved for through numerical studies. Sensitivity analyses are conducted to reveal the effect of different parameters on system behavior.

Summary: This paper studies a two-echelon reverse supply chain involving a remanufacturer and a collector, and analyzes the coordination using buyback contracts. The research finds that under this contract, the risk of uncertainty is divided among the members, and both parties can achieve higher profits, leading to a win-win situation.

Summary: This paper examines the impact of contract unobservability on supply chain performance, finding that manufacturers may benefit from using wholesale price contracts when contract terms are unobservable to competing retailers. The total industry profit may increase under wholesale price contracts in such scenarios.

Summary: The volatility of total factor productivity (TFP) has long-term predictive ability for excess market returns, mainly through its ability to predict real cash flows through inflation. A model with endogenous growth, Epstein-Zin preferences, and price rigidities explains the long-term predictability driven by TFP volatility and its implications for the real economy.

Summary: This study examines the impact of different retailer collusive patterns and information sharing mechanisms on the benefits of each member in supply chains with buyback contracts. The results show that explicit collusion can bring profit improvement, while retailers tend to choose tacit collusion to effectively identify price signals when demand uncertainty is low. The study also finds that under high demand uncertainty, the whole supply chain sustains losses from vertical information sharing in buyback contracts.

Summary: This article introduces a modified SEIR model that takes into account individuals' access to limited medical resources to highlight the central role of medical resources during the pandemic. The study finds that the Fangcang healthcare system has the least number of infections, deaths, and occupied beds. Under certain conditions, a mixed system can lead to fewer infections and deaths than a hierarchy system, but with more occupied beds. Additionally, the Fangcang system performs the best in reducing infections and deaths, even with small medical capacity, under a social distancing policy.
