Customer loyalty and the effect of switching costs as a moderator variable

Abstract

PurposeIn the GSM mobile telephony sector, the main condition for protecting the subscriber base is to win customer loyalty, a key necessity for the maintenance of a brand's life in the long term. To achieve this aim, customer satisfaction and trust must be measured and “switching costs” identified. The latter render subscribers' preference for rival operators more expensive. In this connection, this paper's aim is to measure the effects of customer satisfaction and trust on customer loyalty, and the direct and indirect effect of “switching cost” on customer loyalty.Design/methodology/approachThe data set covered 1,662 mobile phone users in Turkey. The data were analyzed by moderated regression analysis to test the hypotheses.FindingsThe findings of this study show that the switching cost factor directly affects loyalty, and has a moderator effect on both customer satisfaction and trust. Therefore, it plays a crucial role in winning customer loyalty. In short, it is a quasi moderator. However, switching costs was measured as a unidimensional factor, but switching costs in fact contains psychological, financial and procedural sub‐dimensions. Therefore, future research might measure the sub‐dimensions of switching costs and examine their moderating effects.Originality/valueWith respect to the findings, trust has more importance than customer satisfaction in engendering loyalty, since trust contains belief in the brand, which provides positive outcomes not only in the present but also in the future. But customer satisfaction does not contain this dimension. So, the effect of trust on loyalty becomes greater than the effect of customer satisfaction. Therefore, any GSM operator who wishes to preserve its existing subscriber base should concentrate on winning its subscribers’ trust.
