Acquisition, affinity and rewards: Do they stay or do they go?

Abstract

Customer relationship management seeks to understand how to generate profitable customers who enter into a long-term relationship with a firm. In this paper, we examine the role of modes of acquisition and retention programmes on customer lifetime in the context of a credit card issuing bank. While other papers have studied retention programmes such as loyalty card and reward card, there is no published study in the credit card context. Using a rich data set on nearly 5,000 customers observed over a three-year period, we are able to provide detailed insights about the efficacy of these strategies. We show that affinity cards customers and customers acquired through direct mail have longer lifetimes. We also find that reward card programmes generate customers with a shorter lifetime. Finally we re-examine the link between long-life customers and profitability and find that the relationship is weak, consistent with recent findings.
