Dynamic changepoints revisited: An evolving process model of new product sales

David A. Schweidel and Peter S. Fader

International Journal of Research in Marketing, 2009, vol. 26, issue 2, 119-124

Abstract: This paper posits a new framework to model the trial of and repeat purchasing of a new product. While much research has examined underlying shifts in consumer purchasing patterns, the typical assumption has been that the underlying purchasing process remains the same although the purchasing rate may change over time. Motivated by Fader, Hardie, and Huang's development of a dynamic changepoint model [Fader, P. S., Hardie, B. G. S., & Huang, C. -Y. (2004). A Dynamic Changepoint Model for New Product Sales Forecasting. Marketing Science, 23 (1), 50–65], we consider an evolving process as consumers gain more experience with a new product.
