Personalized pricing versus showrooming: competition between online and offline retailers

This study examines how personalized pricing affects customers' showrooming behavior in the duopoly competition with horizontal product differentiation between traditional and online retailers. For the available personalized pricing strategies, we obtained the optimal decisions for both retailers in the scenarios with and without showrooming. Our results indicate that adopting personalized pricing under particular conditions enables each retailer to be more profitable, even in the presence of showrooming purchases. This finding explains why an increasing number of online and offline retailers have implemented personalized pricing based on technical means and consumer purchase records. It is also demonstrated that personalized pricing can counter showrooming behavior of consumers amidst the competition between both retailers, which provides a novel theoretical basis for dealing with cross-channel shopping in multichannel retail competition. We further clarify how retailers can avoid being trapped in a prisoner's dilemma when both sides have access to personalized pricing. Also, the adoption of personalized pricing can improve consumer surplus and social welfare.
