Abstract
Food selling platforms are facing both challenges and opportunities during the COVID-19 outbreak as the enforcement of social distancing protocols has pushed consumers with serious health and safety concerns to shop online. Observing that platforms and their suppliers have adopted blockchain technologies and linked selected information nodes separately to foster consumers’ trust, we establish a game-theoretic model to study the operations decisions and blockchain adoption strategies for a food supply chain consisting of one platform and one supplier. We explore the values and impacts of blockchain on the retailing platform, supplier, and consumers, respectively. An all-win situation is achieved when both members of the supply chain adopt blockchain. We further propose that not all prevalent supply chain contracts can achieve supply chain coordination in the presence of blockchain. In extended studies, we examine the incentives of the supply chain members’ blockchain implementation with consideration of the fixed cost of such adoption, product infection, and tampered information.
