TL;DR: In this article, the authors examined the relationship between corporate image, perceived service quality, trust and customer switching costs, and the relationships among these factors in the Turkish GSM sector, where data was obtained from 1,662 mobile phone users in Turkey via questionnaire.
Abstract: – Corporate image, perceived service quality, trust and customer switching costs are the major antecedents of customer loyalty, and loyal customers may buy more, accept higher prices and have a positive word‐of‐mouth effect. Also we know that the cost of selling to new customers is much higher than the cost of selling to existing customers. Although this fact is apparent to everyone, many companies are still losing customers at a formidable rate. In this context the main aim of this paper is to examine the relationships between these factors and customer loyalty, and the relationships among these factors in the Turkish GSM sector., – Data was obtained from 1,662 mobile phone users in Turkey via questionnaire. The data was analyzed by structural equation modeling (SEM) in order to test all the relationships between variables in the model., – The findings supported the proposed hypotheses, which are consistent with the theoretical framework. Analysis results showed that perceived service quality is a necessary but not sufficient condition for customer loyalty., – In order to generalize the findings from the paper, the model should be studied in different sectors. The contribution of this paper is to model all the relationships between customer loyalty and its antecedents, and to test these relationships simultaneously., – In order to better understand customer loyalty, as well as perceived service quality, corporate image, perceived switching costs and trust should be taken into consideration. Lately, technological change has shifted competition in the GSM sector from price and core service to value‐added services. Therefore, operators should differentiate their services and guarantee their services' quality because of this shift in competition., – In this paper, the effects of all the factors on customer loyalty are analyzed simultaneously via SEM.

TL;DR: In this article, the authors examined the nomological relations among market orientation, learning orientation, and innovativeness in medium-sized business (SMEs) of developing countries and found that market orientation positively impacts firm learning orientation and indirectly impacts firm market orientation.
Abstract: Purpose – The purpose of this paper is to examine the nomological relations among market‐orientation, learning‐orientation and innovativeness in medium‐sized business (SMEs) of developing countries.Design/methodology/approach – The study involves a questionnaire‐based survey of managers from small‐sized‐firms operating in Turkey. A total of 157 usable questionnaires were received from managers. These were subjected to a structural equation modeling (SEM) analysis.Findings – The results show that firm innovativeness positively affects firm performance; firm learning‐orientation positively influences firm innovativeness; firm market‐orientation positively impacts firm learning orientation; firm learning‐orientation mediates the relationship between firm market‐orientation and firm innovativeness; and firm market‐orientation indirectly impacts firm performance via firm innovativeness and learning.Practical implications – This study has implications for SEMs aiming at increasing their performance and innovati...
