Abstract

Online social advertising tools such as Groupon and Living Social generate new business for service providers and at the same time generate new challenges. By doing promotion, a firm may unavoidably attract deal hunters who are less likely to continue to purchase the service after promotion. Even worse, those discount-seeking customers may impose externalities on the system that could drive away regular customers. This paper considers a promotion strategy for a service firm faced with customers who are delay sensitive. We study the equilibrium behavior of such a system and analyze the trade-o˙s of promotion. We find that a service firm benefits from a promotion only when the average waiting time without promotion is low. We devise recommendations regarding when promotions would be beneficial: promotion is more likely to be profitable for a firm with a small market size and high prices. In order to characterize the optimal promotion strategy, we derive approximations of such a system that turn out to be extremely accurate to the optimal solution. Using the approximation, we find that when the price is endogenous, the optimal promotion strategy may arise in two different operations regimes depending on the future discounting factor. If the future discounting factor is large, the system is overloaded in the promotion period and critical loaded in the post-promotion period. If the future discounting factor is small, the system is critical loaded in the promotion period and underloaded in the post-promotion period. When the promotion and price decisions are made jointly, the overloaded promotion strategy is more likely to arise. In addition, promotion size and price are complements in the second order refinement problem. The empirical analysis based on a combination of google business traffic dataset and Yelp academic dataset verifies the main findings in the theoretical analysis.
