Purpose -The aims of the study are: to compare the environmental concern and scepticism levels of the participants and whether or not they display green purchase behaviour; to investigate the influence of environmental concern and scepticism on green purchase behaviour by utilizing the Theory of Planned Behaviour. Design/methodology/approach -The data were collected from participant and non-participant customers of the e-invoicing program of Turk Telecom. Customers were clustered into four groups according to their environmental concerns and scepticism levels. Findings -Research results show that those customers who have a high level of environmental concern and less sceptical reflect a positive attitude, have a high positive subjective norm and perceived behavioural control that motivates them to have stronger intentions to become e-invoice subscribers in the near future. Originality/value -The results found in the paper provide clear evidence supporting the Theory of Planned Behaviour in Turkey. Moreover, while most previous studies have employed undergraduate samples which are not representative of common customers, the present study employed a large and real customer sample which strongly represents customers in general.

This descriptive study was conducted to develop an understanding of consumers' attitudes and adoption of Internet banking among sophisticated consumers. Based on a random sample of academicians, demographic, attitudinal, and behavioral characteristics of Internet banking (IB) users and non‐users were examined. The analyses revealed significant differences between the demographic profiles and attitudes of users and non‐users. IB users were further investigated, and three sub‐segments were defined according to a set of bank selection criteria. Finally, based on the similarities between various Web‐based bank services, four homogeneous categories of services were defined.

This study suggests a new approach to the exploratory and evaluative research of service‐quality dimensions by employing correspondence analysis (CA). Although several studies have investigated the service quality of service providers using descriptive measures and statistical tests, this study presents a graphical interpretation of SERVQUAL data to aid managerial decision‐making in the tourism industry. This paper also examines the expectations and perceptions of two distinct groups by determining the differences between German and Russian tourists’ evaluations of service‐quality dimensions in tour operators. The study concludes that CA can be used effectively in evaluating the service‐quality and displaying the differences in the expectations/perceptions of distinct consumer groups. Managerial implications for travel administrators are discussed. Tour operators should consider cultural differences in service‐quality evaluations.
