Combating fraudulent returns using blockchain technology

Fraudulent returns have become increasingly frequent in the development of online retail platforms, leading to huge losses for retailers. A blockchain-based system can help eliminate this problem primarily because the data stored in a blockchain network cannot be modified. In this paper, we study the impact of blockchain technology that aims to eliminate fraudulent return behavior on retailers and their upstream suppliers. We develop a game-theoretic model that comprises a supplier, a retailer, and customers and analyze the equilibrium outcomes. The results show that the retailer would (not) adopt blockchain technology if the efficiency of the supplier's investment in the innovation of its products is high (low). Moreover, if the retailer's loss from the return is low (high), the adoption of blockchain technology decreases (increases) the supplier's investment and the wholesale and retail prices. In terms of its effect on profitability, we reveal that if the fraudulent return losses are high, using blockchain technology always benefits the supplier; otherwise, it increases retailer profitability and supply chain performance but may make the supplier suffer losses in profits. Interestingly, the retailer would adopt blockchain technology to ensure profitability in situations where the number of customers without fraudulent returns and the intensity of losses are low; however, this weakens supplier profitability and meanwhile reduces supply chain performance.

Automated summary

Fraudulent returns in online retail platforms have caused significant losses to retailers, but a blockchain-based system can address this issue by ensuring the immutability of stored data. This study examines the impact of blockchain technology on retailers and their suppliers in eliminating fraudulent returns. The findings indicate that the retailer's adoption of blockchain technology depends on the supplier's investment efficiency and the magnitude of return losses. Additionally, the use of blockchain technology improves supply chain performance but can lead to varying profitability outcomes for retailers and suppliers.
