AbstractIn a study of telecom services the authors examine the effects customer satisfaction, affective commitment, and calculative commitment on retention. The study further examines the potential for situational and reactional trigger conditions to moderate the satisfaction-retention relationship. The results support consistent effects of customer satisfaction, calculative commitment and prior churn on retention. Prior churn also moderates the satisfaction-retention relationship. The results have implications for both customer relationship managers and researchers using satisfaction surveys to predict behavior.
