“…However, the customers concerned are heterogeneous, that is, they differ in their worthiness, customer behaviour and their reactions resulting from those provider decisions. Since the beginning of the Journal of Revenue and Pricing Management, researchers and practitioners have therefore advocated a shift from transaction-based control (with short-term willingness-to-pay as sole decision criterion) to a customer relationshipbased allocation and booking control focusing on the customers' long-term value for the provider (Belobaba, 2002;Lieberman, 2002;Hendler and Hendler, 2004;Hoff, 2008;Cross et al, 2011;von Martens and Hilbert, 2011). As transaction-based revenue management concentrates on optimising short-term revenue only, the potential negative impact on the provider's relationship with clients, such as loss in loyalty, trust and perceived price fairness, is often ignored (McMahon-Beattie et al, 2002;Wirtz et al, 2003).…”
