We argue that neither measure was actually examined and that conclusions about the predictive value of these measures cannot be drawn from their analysis. A primary problem is that the measures used in Morgan and Rego (2006) do not adequately adjust for the presence of neutral word-of-mouth activity. Nevertheless, Morgan and Rego (2006) provide important information regarding other common customer metrics and firm financial outcomes. We are unaware of another longitudinal study that examines the predictive value of satisfaction and loyalty metrics in such a comprehensive way.BusinessOther256832400015Q210892
