Purpose This study aims to both identify content-based and interaction-based online consumer complaint types and predict complaint types according to the complaint magnitude rooted in complainants' personality traits, emotion, Twitter usage activity, as well as complaint's sentiment polarity, and interaction rate. Design/methodology/approach In total, 297,000 complaint tweets were collected from Twitter, featuring over 220,000 consumer profiles and over 24 million user tweets. The obtained data were analyzed via two-step machine learning approach. Findings This study proposes a set of content and profile features that can be employed for determining complaint types and reveals the relationship between content features, profile features and online complaint type. Originality/value This study proposes a novel model for identifying types of online complaints, offering a set of content and profile features that can be used for predicting complaint type, and therefore introduces a flexible approach for enhancing online complaint management.

Owing to the growing attention of consumers towards green-related issues, important number of studies has been devoted to understanding the drivers of green product purchase intention; implying a need to quantitatively synthesize the empirical body of research on the subject. In this sense, extending the theory of planned behavior, the main purpose of this study is to meta-analyze the empirical findings on green product purchase intention and its antecedents. The meta-analytic investigation was performed on 235 effects dependent upon more than 39,000 consumers (N = 39,253). The findings of the meta-analysis reveal that green product purchase intention is most strongly influenced by attitude toward product/brand, followed by brand trust and self-identity, respectively. This research considerably contributes to the pertinent literature by synthesizing and consolidating fragmented empirical evidence on the determinants of green product purchase intention.

Purpose The purpose of this study is to test Islamic religiosity scale’s reliability and validity and to evaluate the impact of Islamic religiosity on materialism in Turkey. Design/methodology/approach Using a quantitative research method, a self-administered survey was distributed to the students of two faculties – Faculty of Theology and Faculty of Business – of the same university in Izmir, Turkey. In total, 400 questionnaires for each faculty were distributed and a total of 529 completed questionnaires – 326 from the Faculty of Theology and 203 from the Faculty of Business – were returned. Exploratory and confirmatory factor analyses were conducted via SPSS and AMOS. Findings Islamic religiosity and materialism have been found to be negatively correlated, supporting the existing literature. However, not all the dimensions of Islamic religiosity (behavioral religiosity, spiritual religiosity and necessity of religion) had this negative effect on materialism (possession-defined success, acquisition centrality and acquisition as the pursuit of happiness). Negative influence of “behavioral religiosity” on all three dimensions of materialism was observed. However, the “spirituality” dimension of religiosity was found to have a positive impact, while the “necessity of religion” had no significant impact on the dimensions of materialism. Research limitations/implications A sample consisting of undergraduate students might limit the generalizability of the findings to Turkish Islamic population in general. This study is one of the first attempts to test the Islamic religiosity scale which needs to be further analyzed and developed. Originality/value The present study will contribute to the literature by testing an Islamic religiosity scale developed by a Turkish researcher. Besides, this is the only study undertaken on the impact of Islamic religiosity on materialism using an Islamic religiosity scale.

Overconsumption is fueled by the idea that the more people buy, the happier they become; however, this is not compatible with sustainability and the future of the planet. Deep concerns about the sustainability of nature and natural resources give rise to discussions of sustainable consumption, and social innovation applications may lead the way to sustainable consumption. Thus, this chapter aims to provide a picture of social innovation practices in services for sustainable consumption in an emerging economy. Although the chapter focuses mainly on contemporary social innovations, an overview of the social innovation concept and possible historical roots of social innovations from Turkish history are also provided.

In recent years, there has been an emerging literature with regard to brand jealousy and its impact on consumer–brand interactions. This research attempts to explain how brand jealousy influences the motivation of consumers to pay premium prices to specific brands as a means of self-expression theory and social exclusion theory which emphasize the role of social anxiety in explaining the individuals’ behaviors on their purchasing decision-making process. Therefore, the aim of the paper is to examine the mediating role of the materialism on the relationship between brand jealousy and willingness to pay premium. A questionnaire-based quantitative approach is applied to analyze the conceptual model that outlines the relationships between brand jealousy, materialism, and willingness to pay premium through structural equation modeling. The findings of this research reveal that brand jealousy and materialism both have a positive influence on willingness to pay premium. Also, this study provides empirical evidence for the full mediation impact of materialism on the relationship between brand jealousy and willingness to pay premium. The results also ensure applicable insights for marketing practitioners to motivate customers pay premium prices to specific brands by evoking jealousy-inducing strategies and materialistic values in their marketing communication programs.

This study endeavours to develop and analyze a conceptual model that sheds light on the moderating impact of utilitarian and hedonic shopping values in determining the relationship between private label usage and store loyalty. In a test with data collected from 267 consumers, conceptual framework was analyzed by using structural equation modeling. The findings reveal that a negative relationship was observed between private label usage and store loyalty. However, utilitarian shopping value converts this existing negative relationship between private label usage and store loyalty into a strong positive association. This study offers such interesting implications for managers that developing marketing strategies oriented to create utilitarian shopping value during the shopping experience may enable retailers to enhance their store loyalty in a positive way in the long run. Prior research has not approached the private label product phenomenon from a shopping value perspective. Hence, this study attempts to measure the moderating impact of shopping value on the linkage between private label usage and store loyalty for the first time.

The main objective of this study is to investigate the relationship between the usage of web based user innovation tools and firms’ innovativeness. Besides, it is also aimed to explore the tools that are used in conjunction and trigger innovativeness. 61 firms operating in consumer goods/services sector within the list of Fortune Top 500 Turkey List, published in 2014, responded to the questionnaire. Findings reveal that not all of the web based user innovation tools have a significant relationship with firms’ innovativeness. Hypotheses of the study are tested by correlation analysis and research questions are investigated via mining association rules with FP-Growth algorithm. The association rules mined pinpoint that 71% of the companies that use “virtual communities formed by users, and marketing intelligence services” together and 65% of the firms using market intelligence services in their new product development process are found to trigger innovativeness. Up to date, to the best of our knowledge, there has been no research focusing on the relationship between the usage of web based user innovation tools and firms’ innovativeness. Therefore, the most important contribution of this study is being a pioneer attempt to provide an empirical evidence for the aforementioned relationship by shedding light on each tools’ effect on firm’s innovativeness for consumer goods/services. Web based user innovation tools are the prominent enablers of customer integration into innovation processes of firms leading to customer generated value. Thus, it may be important for firms to decide on the bundle of the web based user innovation tools to be used; since the usage of these tools together or separately might have different effects on firms’ innovativeness.
