Quality Management and Blockchain Adoption in a Supply Chain

In the past, it was difficult to check, identify, and trace product quality. Quality violation regularly takes place when consumers know product quality is overstated. In this paper, we examine the motivation for and implication of a supply chain that adopts blockchain technology to improve product quality in supply chains. We build up a stylish model in which a two-echelon supply chain consisting of one manufacturer and one retailer. The manufacturer decides whether or not to adopt blockchain and the retailer sells products to consumers. Our results imply that the manufacturer always provides a low-quality product without blockchain but when the quality-cost ratio is sufficiently high with the affordable blockchain adoption cost, blockchain technology could encourage the manufacturer to produce high-quality products.
