Abstract

To cope with counterfeit drugs reaching consumers all over the world, pharmaceutical firms increasingly regard blockchain technology (BCT) as a promising solution to achieve drug traceability. This study proposes a game-theoretic model to investigate the impact of BCT adoption on pharmaceutical firms’ pricing and performance in a competitive market, where one firm offers a branded drug and the other offers a generic version. We consider three contrastive cases with no BCT adoption, unilateral BCT adoption of the branded drug firm and bilateral BCT adoption and characterize consumer traceability awareness, which represents the fraction of consumers sensitive to drug traceability. We find that when BCT is unilaterally adopted, a high consumer traceability awareness level may lead to either higher or lower drug prices. The bilateral adoption of BCT always benefits the generic drug firm due to the enhanced drug traceability, but may damage the branded drug firm attributed to the mitigated differentiation between the two drugs. Compared with the unilateral adoption of BCT, bilaterally adopting BCT can lead to a win-win or lose-lose outcome, depending on the trade-off of drug traceability, drug differentiation and pricing competition. In addition, the adoption of BCT improves consumer welfare when consumers hold a high level of traceability awareness.
