Workers in developing economies may be forced to work excessive overtime, which not only causes severe mental and physical issues to the workers but also results in significant brand damage to the buyers if exposed in public. In this paper, we develop a game-theoretic model of a dyadic supply chain and analyze the buyer’s strategies to combat such excessive overtime issues of the supplier, including auditing the supplier’s practice and conducting supplier development activities.
Supply disruption in multi-tier supply chains: competition and network configuration
Sean Zhou, Kevin Chen, Yixin Zhu
Chinese University of Hong Kong
Problem: Studying disruption impact on centralized and decentralized supply chains. Methodology/Results: Analyzing three-tier supply chain with disruption and network incompleteness. Centralized supply chain maximizes profit. Managerial Implications: Complete network favors centralized supply chain for higher profit and reliability. Incomplete network amplifies disruption's negative impact, reducing profit by up to 20%/30%.
Building supply chain resilience and mitigating disruption risk through vertical integration

In this paper, we examine the value of vertical integration as a disruption risk mitigation strategy. Vertical integration increases firms' control over their supply chain and could reduce the risk of production being disrupted due to material or component shortages. Using a stylized model of a manufacturer sourcing a critical component from a multi-tier supply chain, we show that vertical integration is most valuable for moderate probability, severe disruptions that are positively correlated.
