Perceived equity is a key psychological reaction to the value that a service company provides. Yet equity research has focused on a customer’s satisfaction with relatively well-defined service episodes or transactions. The authors argue and show that equity plays a very different role in affecting customer loyalty as one moves from transaction-specific to cumulative evaluations. Whereas equity is an important driver of transaction-specific satisfaction, equity is more of a postsatisfaction evaluation when modeling cumulative satisfaction. The research also demonstrates the superiority of cumulative evaluations toward explaining service loyalty and providing a balanced view of loyalty drivers. The results have important implications for how equity, satisfaction, and loyalty are modeled and managed in a service context.
