Customer churn is one of biggest concerns for businesses operating in both contractual and non-contractual industries. Firms need to detect early who? is most likely to churn, when?, and why? to proactively prevent the loss of customers. Because retention budgets are limited, firms also recognize that some customers are more valuable than others, and they simply cannot afford to lose them. Furthermore, there is evidence from the marketplace that firms do not give up on lost customers but try to profitably rebuild those relationships. My research on customer relationship marketing tackles these strategic challenges.
