报告简介

In the presence of successive product generations, most customers are repeat buyers, who may decide to purchase a future product generation before its release. As a result, after the new product generation enters the market, its sales often exhibit a declining pattern, thus rendering traditional diffusion models unsuitable for characterizing customers’ time to product upgrades. In this study, we propose an Exponential-Decay proportional hazard model (Expo-Decay model) to predict customers’ time to product upgrade. Compared with existing proportional hazard models, the Expo-Decay model is parsimonious and easy to interpret. In addition, our empirical test shows that the Expo-Decay model performs better than or as well as existing parametric models in prediction accuracy. Furthermore, we develop and test three extensions of the Expo-Decay model. We apply the Expo-Decay model as well as the three extensions to study customers’ update behaviors for a sports video game series produced by a major U.S. firm. Empirical results reveal that customers’ previous adoption and usage patterns can help predict their timing to upgrade to a new product generation.
