ABSTRACT The concept of consumer ethnocentrism has been in the centre of scholarly inquiry for more than twenty years. The original dimensionalisation and operationalisation of the construct has been introduced in the marketing literature back in 1987. Since then the relevant literature unquestionably applies the existing scale, namely the CETSCALE. This thesis seeks to explore consumer ethnocentrism facets under the light of increased globalisation and integration and consequently develop an enhanced measurement instrument. A mixed methods approach is pursued and as a result, several deviations from the original conceptualisation and operationalisation of consumer ethnocentrism are evidenced. Although some of the already established dimensions prevail to be equally relevant in these days, there are numerous other areas that the CETSCALE fails to capture. In particular, the new, extended scale (CEESCALE) encapsulates the novel notions of impure altruism and self enhancement, social demonstrability of benefits of consuming domestic products and finally, buying inertia. Following the development of the CEESCALE, construct validity is established. The superiority of the CEESCALE to the CETSCALE is attested by better predictive validity estimates. ACKNOWLEDGMENTS This research would not have been possible without the contribution of a number of people. I would like to thank my parents, Giannis and Pitsa, for their love and continuous support. Their trust in me and my work was a significant motivation and a driving force towards a better result. I would have never managed to complete this thesis without them. I would also like to thank my supervisors, Dr Svetla Marinova and Dr Eric Shiu for their support. They both devoted a significant amount of time and effort for this research. Their advice and feedback were vital for the completion of the thesis presented. A special thank you should go to Professor George Balabanis, who had the patience to discuss for hours several aspects of this research. His knowledge and his support were crucial for the completion of this thesis. He was definitely a source of inspiration for me. Last but not least, I would like to thank my good friends Katerina and Konstantinos for their encouragement. They were there to help me stand on my feet again throughout the difficult times of my Ph.D. life. I would like to also thank Loukas, Anna and Ioanna for being there for me whenever I needed help. A final word of thank you should go to George, for the valuable pieces of advice, the long but always interesting discussions and the unconditional support he offered me. He certainly made my life in Birmingham more enjoyable.
