Recently, corporate damage and negative effects have been on the rise by some malicious consumers, called “Deviant consumer behavior." Other good consumers are also suffering from them, which is no exception in the bank industry. Currently, some in-depth studies on the behavior and concepts regarding deviant consumer behavior have been conducted; yet, none of them were investigated in the context of bank industry. To fill this gap, this study attempts to identify the types of deviant consumer behavior (i.e., obstinate, intentional, habitual, deceptive, and excessive) in the banking context. In addition, the effects of deviant consumer behavior on the possibility of negative word-of-mouth and recurrence are empirically examined. Furthermore, the moderating role of work types (i.e., face-to-face vs. non-face-to-face) in these relationships is also investigated in the context of banking. 176 samples from survey questionnaire were collected from employees in the bank industry, and empirically tested using a structural equation modeling technique. The results show that intentional and excessive types of deviant consumer behavior have a significant impact on the possibility of negative word-of-mouth, while, exception for the obstinate type, all other four types of deviant consumer behavior have a significant effect on possibility of recurrence. In addition, it is found that work types have a moderating effect on the relationship between the five different types of deviant consumer behavior and the possibility of negative word-of-mouth and recurrence. As the importance of dealing with deviant consumer behavior grows especially in the banking environment, the results of this study would provide some guidelines to managers who want to distinguish individuals with deviant consumer behavior from general consumers and develop specific and active response strategies for different types of deviant consumer behavior.
