Whilst the rapid advancement of technology in the 21st century has facilitated the online collection, storage, retrieval, manipulation, and transmission of individuals' personal information, it has also led to a concomitant rise in privacy concerns amongst e‐commerce users. Although privacy concerns have received considerable attention in the e‐commerce literature, to date, empirical research has tended to report somewhat erratic and inconsistent findings in the context of consumer privacy. Accordingly, the relationships between the antecedents, privacy concerns, and the outcome variables in e‐commerce contexts remains unclear. To remedy such deficiencies in the literature, this study adopts the meta‐analytic approach to gather and make sense of the inconsistent and mixed empirical findings reported in the literature. The findings show that risk perceptions trigger privacy concerns while benefit perceptions, familiarity, reputation, privacy policy, and trust mitigate privacy concerns which in turn affect customer attitude and usage of e‐commerce platforms. To investigate the possible reasons for inconsistent findings, we performed a moderation analysis which suggests that methodological moderators, that is, type of article, research methods, and sample type; and contextual moderators, i.e. country where the study was carried out, and gender dominance in a sample set, can cause inconsistencies in the findings. Theoretically, this meta‐analysis contributes to the Antecedents; Privacy Concerns; Outcome variables (APCO) Model, and the literature on consumer privacy in the context of e‐commerce. Practically, the findings provide guidelines to e‐commerce businesses to effectively address customers' privacy concerns.

The purpose of this research is to review the extant literature on mobile advertising systematically and to carry out a comprehensive analysis of research in this emerging field. Accordingly, this paper synthesises the literature on mobile advertising in terms of theories, contexts, characteristics and methodology to analyse the development of mobile advertising research over time. The literature review shows that mobile advertising research has transitioned from text message-based SMS advertisements into internet-based smartphone advertising. Furthermore, based on the synthesis, we have developed a conceptual framework that shows the antecedents, mediators and consequences of mobile advertising. Additionally, we have identified some overlooked areas and proposed some insightful research directions to advance this field of research. This review contributes to the mobile marketing literature, specifically to the mobile advertising literature.

PurposeThe purpose of this study is to present a systematic review of the online service failure (OSF) literature and conduct an exhaustive analysis of academic research on this emerging research area.Design/methodology/approachThe current study has adopted a structured systematic literature review approach to synthesize and assess the OSF literature. Further, the study uses the Theory-Context-Characteristics-Methodology (TCCM) framework to propose future research directions in the OSF domain.FindingsThis systematic review shows that OSF research is still developing and remains mainly incoherent. Further, the study develops a conceptual framework integrating the frequently reported antecedents, mediators, moderator and consequences in the extant literature. This review also synthesizes the theoretical perspectives adopted for this domain.Research limitations/implicationsThe study followed specific inclusion and exclusion criteria to shortlist articles. Further, articles published only in the English language were considered. Hence, the findings of this review cannot be generalized to all OSF literature.Practical implicationsThis systematic review has classified antecedents into customers' and service providers' roles which will enable online service providers to understand all sets of factors driving OSF. It also synthesizes and presents service recovery strategies and emphasizes the role of online customer support to fix OSF.Originality/valueThe OSF literature is still developing and remains highly incoherent, suggesting that a synthesized review is needed. This study has systematically reviewed and synthesized the OSF literature to study its development over time and proposes a framework which provides a comprehensive understanding of OSF.

This study synthesizes the artificial intelligence literature into a Meta-analytic framework based on the theory of reasoned action and the unified theory of acceptance and use of technology 2, and examines concrete relationships between the constructs of this framework. This meta-review also performed a moderation analysis to investigate the possible reasons for inconsistent findings across studies.The findings suggest that three methodological moderators (sample type, gender dominance, and publication type), and one contextual moderator (level of country's technology advancement) lead to inconsistencies in the relationships between study constructs. Academically, this review synthesizes the artificial intelligence literature and resolves inconsistencies in the literature and also adds constructs to both theory of reasoned action and the unified theory of acceptance and use of technology 2.

Researchers have given considerable attention to investigate anti-consumption behavior. However, empirical research tends to report somewhat erratic and inconsistent findings. Accordingly, the relationships between the antecedents, and the outcome variables of anti-consumption behavior, such as consumer well-being, remain unclear. Thus, to fill this void in the literature, this study integrates Attitude Behavior Context (ABC) theory and Well-being theory into a meta-analytic framework and synthesizes the extant literature on anti-consumption to examine concrete relationships between the contextual and attitudinal variables, anti-consumption behavior and consumer well-being.The findings show that ecological concern, religiosity, mortality salience, and perceived behavioral control influence anti-consumption attitudes and intention, whereas consumer well-being is the outcome variable of anti-consumption behavior. To investigate the possible reasons for the inconsistent findings, we performed a moderation analysis which suggests that country of study, product type, data collection period, research methods and sample type may cause inconsistencies in the findings. This meta-analytic study contributes to the anti-consumption literature. Practically, the findings provide guidelines to policymakers and societal organizations interested in promoting anticonsumption.

Purpose Collaborative consumption (CC), a unique business model, provides several monetary and non-monetary benefits to customers. Several adapted theory of planned behaviour (TPB)-based models were developed and tested to understand this consumption behaviour with the findings inconsistent and fragmented. Thus, this study aims to develop a general and consistent TPB model using a meta-analytic path analysis to better understand customers’ CC adoption behaviour. Design/methodology/approach Using 37 studies, a meta-analysis was performed adopting several analytical methods; bivariate analysis, moderation analysis and path analysis. Findings The universal TPB model shows that factors, that is, trust, attitude, perceived environmental responsibility and communication facilities, drive both perceived usefulness and CC. However, subjective norms, such as perceived behavioural control and emotional value, drive only perceived usefulness. Moderation analysis shows that the relationships between variables used in the proposed TPB model tends to vary depending on five moderators, that is, countries’ economic development level, type of CC, sample size, sample type and survey administration method. Research limitations/implications The consideration of only quantitative papers and papers written in English language in this meta-analysis may bias the study’s findings. Practical implications Based on the findings regarding important factors that consumers consider when adopting CC, this study provides insightful recommendations to companies facilitating CC. Originality/value By developing the universal TPB model, this study theoretically contributes to the TPB model, and by conducting the moderation test, the study contextually contributes to the TPB literature in the CC context.
