Retailers are increasingly turning toward self-service technologies (SSTs) aimed at improving productivity and service quality while cutting costs. The authors identify a process model to understand the antecedents and consequences of SST usage by customers in an in-store retail setting. The model was validated on a combination of survey and observational data. Perceived usefulness, perceived ease of use, reliability, and fun were identified as key drivers of customer attitude toward the SST. Customer attitude toward the SST predicted the actual usage of technology. The effects of SST usage on the actual time spent by customers in the store were studied. The authors investigate the impact of SST usage on customers' perceptions of waiting time and, consequently, on their level of satisfaction with the shopping experience. Finally, the moderating effects of age, education, and gender are analyzed. The current study evaluates the benefits of SST introduction for both customers and retailers.

There has been little research on how market disruptions affect customer-brand relationships and how firms can sustain brand loyalty when disruptions occur. Drawing from social identity theory and the brand loyalty literature, the authors propose a conceptual framework to examine these issues in a specific market disruption, namely, the introduction of a radically new brand. The framework focuses on the time-varying effects of customers' identification with and perceived value of the incumbent relative to the new brand on switching behavior. The authors divert from the conventional economic perspective of treating brand switching as functional utility maximization to propose that brand switching can also result from customers' social mobility between brand identities. The results from longitudinal data of 679 customers during the launch of the iPhone in Spain show that both relative customer-brand identification and relative perceived value of the incumbent inhibit switching behavior, but their effects vary over time. Relative customer-brand identification with the incumbent apparently exerts a stronger longitudinal restraint on switching behavior than relative perceived value of the incumbent. The study has important strategic implications for devising customer relationship strategies and brand investment.
