This study examines the potential of RFID technology to increase the agility of supply-chain e-commerce systems by mitigating the bullwhip effect. The bullwhip effect is a supply-chain phenomenon that reveals a lack of business agility characterized by the amplification of inventory variance. This study employs an experiment involving a modified Beer Distribution Game to simulate an RFID-enabled supply chain. The results provide empirical evidence that RFID technology can increase a supply chain’s agility and reduce the bullwhip effect by reducing inventory holding costs, stockout costs, and inventory-level variances. The results are all the more important when applied to interorganizational e-commerce systems.
