Economic sanctions and shared supply chains: A firm‐level study of the contagion effects of smart sanctions on the performance of nontargeted firms

Abstract

We examine the effects of targeted economic sanctions on the performance of nontargeted firms sharing a common supply chain with targeted firms. We build on sanctions literature and contagion theory to develop a conceptual model that encapsulates the nexus between targeted sanctions, supply chains, and firm performance. Drawing on data from Zimbabwe, we find that nontargeted firms in the same supply chain as sanctioned firms perform poorly compared with other non‐sanctioned firms, signaling the effects of contagion. The mediation test indicates that economic sanctions reduce the performance of nontargeted supply chain member firms through reducing sales and increasing the cost of products, showing significant mediating effects. We also show that exports greatly affect nontargeted firms that depend heavily on targeted firms, whereas imports have a relatively low impact. The results of this study extend previous research on the adverse consequences of economic sanctions and supply chain networks and provide important guiding significance for firm managers, investors and policymakers on how to respond to smart sanctions.

Justice in supply chain relationships: A comprehensive review and future research directions

“…Intensifying competition, ever‐changing customer preferences, shrinking product lifecycles and cost pressures have increasingly pushed organisations to rely more on a network of partners across the supply chain to obtain input materials/services and develop, manufacture and deliver their products/services to customers in the most possible efficient and effective way (Alghababsheh & Gallear, 2022; Hornibrook et al, 2009; Sun et al, 2022). As this trend continues to rise, the focal company's product performance in the marketplace becomes undoubtfully more dependent than ever on the coordination between and performance of its supply chain partners (e.g., suppliers, distributors and logistics service providers).…”

Sanctions risks and regional development: Russian case

“…The restrictions could lead to a decrease in economic activity and employment. Sanctions against one company inevitably lead to risks along the value chain [25]. Therefore, this influence was stronger if the role of the organizations in the regional economy was higher.…”
