A theoretical model of interpurchase times

Abstract: A theoretical model of interpurchase times at the individual level is developed. This model provides a bench‐mark for the expected regularity of a product's purchase cycle in the absence of any confounding external marketing activity. Products which empirically deviate from the theoretical expectations can then be further studied to determine the causes of the deviations. The theoretical model also tests the robustness of the assumption of a gamma distribution at the individual level, an assumption which is frequently made in the marketing literature.
