Online consumer shopping behaviour: A review and research agenda

Over the last two decades, motivated by the continuous evolution of the technology-driven retail environment, researchers have studied various aspects of online consumer behaviour. This article attempts to take stock of this environment to critically assess the research gaps in the domain and provide future research directions. Applying a well-grounded systematic methodology following the TCCM (theory, context, characteristics and methodology) framework, 197 online consumer shopping behaviour articles were reviewed. The findings reveal that the application of theories remains limited in the current pool of literature that focuses more on developed nations. While studies have primarily considered categories such as apparel and grocery, in terms of methodology experimental and survey-based studies were most common. Additionally, the article suggests some future research directions. The use of combined theories to better understand technology acceptance by consumers of online-shopping is recommended. Similarly, studies across other categories like online experiential luxury, luxury services, or second-hand products that then link to novel constructs reflecting issues with payment methods, online service quality, and online store atmosphere are portrayed as meaningful avenues that will advance research in the domain.     

Consumer behaviour in cross-border e-commerce: Systematic literature review and future research agenda

Cross-border electronic commerce (CBEC) was developed from traditional e-commerce to cater to the growing demand for online transactions among global traders. Consumer behaviour is one of the most important topics that multistakeholders (e.g., e-commerce platforms, entrepreneurs, governments and third-party service providers) need to understand to develop CBEC. Although for over a decade studies across disciplines and regions have explored various consumer behaviours and their factors in CBEC through diverse research methods and theoretical lenses, the current literature is still fragmented and lacks consolidation of past contributions. In the present study, we conduct a systematic literature review based on 40 CBEC studies to present an overview of the current research status of the field. This study analyzes research contexts, theoretical applications and methods, and unifies a CBEC definition as a benchmark for future research. More importantly, we employ the Stimulus–Organism–Response (S–O–R) framework to categorize factors into the inner and outer CBEC ecosystem stimuli, cognitive and affective states, and approach and avoidance behaviours, and to generalize two consumer behavioural patterns to provide a comprehensive understanding of consumer behaviours in CBEC. With the proposed future research directions, we believe that this review can serve as a fundamental and informative guideline for researchers to continue advancing knowledge of the field.     

Emotions and consumer behaviour: A review and research agenda

Consumers' emotions play a salient role in consumers' buying process, their consumption behaviours, and their engagement with product/service offerings, owing to which, it has gained much attention in recent years as an area of inquiry. However, literature in this field/subject is theoretically fragmented. Therefore, to enhance the conceptual understanding, this study synthesizes extant literature, using a hybrid review approach. Herein, we attempt to integrate bibliometric analysis, along with the theories, contexts, characteristics, and methodology framework, while consolidating and classifying the domain knowledge, trends, and progress/citation analysis using the bibliometric approach. In the process, we reviewed 384 conceptual and empirical articles, published during the period 1967–2021. The idea was to identify key theories, constructs, research contexts, and methods, based on which, we propose a few potential research areas. Based on our thorough analysis, these areas include (1) consumer co-creation, (2) consumer engagement, (3) service employee interactions, (4) consumer decision making, and (5) consumption experience.     

How to maintain sustainable consumer behaviours: A systematic review and future research agenda

Maintaining sustainable consumer behaviours is necessary for both mitigating environmental problems and the success of sustainable businesses. However, to date, the focus is mainly on the motivation-adoption link (i.e., how to motivate sustainable consumer behaviours) rather than the adoption-continuance link (i.e., how to maintain those behaviours). This study addresses the link between sustainability adoption and continuance, through a structured literature review. Specifically, this study synthesizes what is (and is not) known about the post-adoption (continuance) stage of the sustainable consumer journey, by reviewing and integrating the results of 87 articles. This review has three key outcomes. First, it elaborates on the importance and distinction of the continuance stage, which is predicted by a set of different and ‘evolving’ factors, compared with motivation and initial adoption. Second, the key components of the continuance stage are identified and grouped under (I) post-adoption cognitive perceptions, (II) emotional outcomes, and (III) subsequent behavioural patterns of (dis)continuance, spillover, advocacy, loyalty and habit formation. Third, this study introduces the concept of sustainable consumer behaviour continuity and discusses theoretical relationships in a conceptual framework. Finally, this review identifies knowledge gaps and provides research directions as well as implications for theory and practice.     

Blockchain application in consumer services: A review and future research agenda

The potential of blockchain technology (BCT) to modify and innovates established business structures and frameworks has received widespread attention. Academia and businesses are becoming increasingly curious about how this technology could be used to improve and refine consumer services and operations. Despite the growing popularity of blockchain research in consumer services, there remains a dearth of detailed summaries in the literature. Hence, this bibliometric analysis, combined with a systematic literature review (SLR) using SPAR-4-SLR protocol with the theories, characteristics, contexts, and methods framework (A hybrid review), aims to convey qualitative and quantitative knowledge on the ever-evolving subject of blockchain application in consumer services in an organized manner. Specifically, this article analyses: (1) the current publication trends in studies devoted to blockchain-based applications for consumers, (2) the most important publications and themes of research in this field, (3) the evolution of blockchain in consumer service over the years, and the most current trends in this field, (4) the advantages and challenges of incorporating BCT into consumer services, (5) gaps in the existing literature that future researchers should investigate. In addition, this review also describes the widely used theories, characteristics, and methods in the application of blockchain in consumer service research by examining the most applied theories, methods, constructs, and study contexts and paving the way for new research directions. The review includes 417 documents after searching for scholarly publications in two databases (Web of Science and Scopus) and choosing documents based on their relevance to the stated goals.     

Consumer ethics: A review and research agenda

Consumer ethics continues to draw the attention of academicians and practitioners as a significant economic and social issue globally. Consumer ethics refers to moral principles that govern a consumer's behaviour. This literature review seeks to enrich the discourse on consumer ethics through a comprehensive and detailed review of 106 articles, covering 21 journals from 2010 to 2020. Through an examination of theories, contexts, characteristics, and methodologies used in consumer ethics research, our review (1) presents a comprehensive and up-to-date overview of the research in this field and (2) sets a future research agenda to spur scholarly research. We found studies have primarily relied on a single theoretical lens such as the theory of marketing ethics, planned behaviour, and neutralization theory. Further consumer ethics research focuses on advanced countries, with a narrow focus on developing countries. We have diagnosed the need to examine boundary conditions impacting consumer ethics. Finally, we provide actionable inputs to combat unethical consumer actions as well as promote ethical consumption.     

Social media influencers and consumer engagement: A review and future research agenda

The rise of social media influencers (SMIs) in the recent decade garnered wide interest from academicians and marketers. Academicians try to understand the effect of influencers on consumer behaviour, while marketers use influencers as part of their strategy to achieve marketing objectives. Although, plenty of practical and conceptual research is available in this area, literature reviews in the domain of SMIs and consumer engagement are scarce as it is still developing, and most of the studies have focused on these two concepts separately. In this study, the authors attempted to combine and understand how social media influencers affect consumers engagement. This systematic review of the literature offers a comprehensive view of previous research on social media influencers and consumer engagement. The study reviewed articles published in the Australian Business Deans Council (ABDC), Scopus, and Web of Science indexed journals till 5 June 2021. To understand consumers' engagement with SMIs, authors identified and theorized the antecedents, decision and outcome of such engagement. It also discusses the influencer-follower parasocial relationship on different social media platforms. The study proposes an integrated conceptual framework that can be further used to test and validate the impact of social media influencer's marketing efforts on consumer engagement. This framework also may serve as a foundation for marketers to develop effective influencer strategies for brand promotions. The review concludes the discussion by highlighting theories, methodology, and context of studies conducted by past researchers.     

Fuzzy-set qualitative comparative analysis in consumer research: A systematic literature review

The traditional symmetrical methods may not be sufficient for effectively examining the asymmetries that are evident in the real-world complex consumption context in the form of pandemic, and other technological, sociocultural, environmental, and geo-political factors. As a result, the use of innovative and asymmetrical methods such as fuzzy-set qualitative comparative analysis (fsQCA), which draws from the complexity theory could help better predict and explain consumer decisions in the age of disruptions. Through a comprehensive method-based systematic literature review of 129 research articles published in the consumer behavior research literature, this study helps to identify the key trends, leading publication sources and contributors, and the current knowledge structure of consumer research using fsQCA. In doing so, this review also sheds light on the state of diversity within this particular area of research. The findings help identify the key future avenues for utilizing fsQCA within consumer research. This review is a useful resource for practitioners to gain a direct access to key consumer research scholars for identifying the constructs (e.g., antecedents, mediators, moderators, enablers, inhibitors) shaping consumer behaviors to inform strategic decisions.     

Modelling real-time online information needs: A new research approach for complex consumer behaviour

Abstract

A major challenge for online vendor website operations is serving information that meets visitor needs at a given point in their purchase process. The problem arises from the complexity of human behaviour, as well as changing needs with the evolution of consumer knowledge and skills through the purchase process. The most difficult element, however, is determining the effects of information provided on the site, as well as from other sources that the consumer may access, and anticipating resulting consumer needs. This paper discusses the contributions and limitations of current modelling techniques and utility studies of online consumer information to model consumer needs in real time. An alternative basis for real-time customer need appraisal is proposed using clickstream and customer input data combined with online information utility to enable more effective information serving. This requires further academic research and changes in practitioner online marketing operations.     

A review of social roles in green consumer behaviour

Despite the broad interest and rapid increase in studying green consumer behaviour (GCB) from a social perspective, related articles have been presented in a piecemeal fashion and have lacked a review of social roles in GCB. Additionally, the research focus may differ from the influence of digital technology. Therefore, this study draws on a review of 439 GCB articles that focus on social roles and utilizes both quantitative and qualitative analyses to provide a general picture of theories, social factors, research topics and topic trends with a specific emphasis on the research differences between the traditional and digital contexts. The findings indicate that the GCB field has experienced exponential growth since 2014. Subjective norms, social influence, culture, marketing influence and social media influence are the main drivers of GCB. Eight research topics are identified, among which topics on the theory of planned behaviour (TPB) and the theory of consumption values (TCV) maintained high popularity. Furthermore, the TPB is more prevalent in the traditional context in which scholars prefer to predict GCB using macrosocial factors, such as policy and culture. In comparison, signal theory and commitment-trust theory have received more attention in the digital context in which trust is vital. Research interests in online platforms and green hotels have recently increased in the digital context. Gaps and suggested directions for future studies are further identified.     

Towards a richer understanding of consumers in social marketing contexts: Revisiting the stage of change model

Abstract

In this paper, we present data from an 18-month-long longitudinal study of a sample of 40 people who received a test for cancer and who were subsequently advised by health professionals on the dietary changes that would lead to improved health. This study investigates the ways that behaviour change is instigated (or not) and how people cope with these changes. We use the Stages of Change model to categorise people by their dominant behavioural response to the test (maintainers, recyclers, no change). From these categorisations, we develop an in-depth understanding of the experience of their behavioural response. By looking at the three possible behavioural responses in this way, we provide insights into the different cognitive, emotional, and behavioural response to the disease trigger. We evaluate the implications for social marketing theory and public policy makers.     

Customer experience in social commerce: A systematic literature review and research agenda

Social commerce (SC) is an upcoming trend that has changed the online shopping experience by allowing e-retailers to develop long-term relationships with customers and increase sales. Empowered by Web 3.0, SC offers many-to-many interactions, enhancing the quality and quantity of social interaction related to the seller–customer, information searches, and product/service delivery. The customer experience (CEX) has been well developed both in the online and offline contexts. However, limited attention has been paid to examining CEX in the SC setting. This study aims to conduct a systematic review of the literature to develop a conceptual framework exploring both the antecedents and consequences of CEX in the SC setting. In the process, we make three significant contributions to academia and practice. First, the study contributes to our understanding of CEX in the context of SC. Second, it proposes a conceptual framework by identifying antecedents of CEX and potential consequences using the consumer culture theory. Finally, it highlights a subject relevant to academia and practice while proposing recommendations for further research.     

Consumer involvement and marketing in Africa: some directions for future research

Despite an ongoing debate, authors agree that factors that determine consumers' involvement in any goal object are the characteristics of the object, the characteristics of the customer involved and the situational context of the decision. With this as the theoretical background, this paper advocates the need to study African‐specific contextual factors to gain a thorough understanding of consumer involvement and successful marketing practice in this society. An extensive review of the extant literature was done to provide a relevant framework for exploring consumer involvement and African‐related issues. The paper concludes that existing postulations on the subject matter could not robustly capture consumer involvement in Africa due to pertinent influences of cultural values and mores that do not apply elsewhere in the world. Hence, empirical studies to gauge the context‐specific application of the subject in relation to Africa are suggested as imperative. This paper advocates a society‐oriented consciousness for marketing activities in relation to consumer involvement with specific reference to Africa. Therefore, it cautions against undue generalization about the existing postulations on the subject, and provides directions for future research towards updating the literature.     

Towards an integrated debiasing framework for consumer financial decisions: A reflection on debiasing research

Consumers are subject to cognitive biases, which impede the rationality of their financial decisions. This is problematic, given the onus on the individual to make investment and savings decisions. Thus, there is an impetus for research to identify mitigation strategies. This qualitative review surveys the debiasing literature to identify the prevalent debiasing approaches and proposes an integrated model towards debiasing. The identified core debiasing strategies (education and training, decision support systems, information aspects, experience, and financial advice) are organized and integrated into a single model using the ‘Antecedents, Decisions, Outcomes’ format developed by Paul and Benito. We also propose an agenda for future debiasing research.     

Celebrity endorsements: a literature review and research agenda

This paper presents a narrative review of celebrity endorsement research. The review identifies six areas of research on celebrity endorsements (celebrity prevalence, campaign management, financial effects, celebrity persuasion, non-evaluative meaning transfer, and brand-to-celebrity transfer). A review of the research in each area identifies key findings, conflicting results, and research gaps. In addition, this paper reviews the celebrity endorsement literature with a focus on the psychological processes underlying celebrity endorsement effects that has been put forward in the literature. Based on the review an agenda for future research is offered.     

Phronesis in administration and organizations: A literature review and future research agenda

Phronesis is essential for good decision-making and actions. This literature review shows how phronesis has been discussed and related to elements of the field of administration and organizations. A search in the database systems Scopus, EBSCO, Web of Science, and Scielo, based on eligibility criteria, resulted in 43 theoretical and 14 empirical works. The analysis of these studies showed the most significant empirical contributions, the most cited authors, methods, journals, and central themes addressed in studies on phronesis to understand ethics in business. From a virtue ethics perspective, we discuss the major theoretical and empirical contributions, as well as the implications of a restricted understanding of phronesis when it is treated apart from other elements of the virtue ethics framework. We present a synthesis of the concepts of phronesis, based on dimensions of magnitude and amplitude of the conceptions, ranging from formal to substantive phronesis, and covering individual, organizational, or societal levels of analysis. We argue that a substantive conception of phronesis within virtue ethics may improve our understanding of ethics because it assumes the interdependence of phronesis and moral virtues, integral anthropology, and the common good. We present a future research agenda, considering the study's limitations and findings.     

The influence of extrinsic product attributes on consumers’ food decisions: review and network analysis of the marketing literature

ABSTRACT

The paper synthesises the existing research on the influence of key product characteristics on the consumers’ food decision-making. By applying network analysis on a sample of 233 empirical studies from the last three decades, the paper demonstrates how marketing-specific variables are embedded in a network of other predictors. The paper also analyses network structure and density using well established measures. The results show that there is still a lack of research concerning the interplay between marketing-relevant extrinsic product attributes (e.g. price, brand, labelling, country of origin) and intrinsic food attributes, policy-related factors, as well as aspects of the proximal and distal environment. The paper identifies gaps in the marketing literature and derives research propositions. Additionally, implications for marketing practice are developed.     

Theory of planned behavior in consumer behavior research: A systematic literature review

This study aimed to systematically review and categorize studies on consumer behavior based on theory of planned behavior (TPB), its core constructs, or extensions, and to provide directions for future research agenda. Scopus and the Web of Science were consulted for studies based on TPB, its parts, or extensions. The inclusion criteria were studies published in peer-reviewed journals, in English, and within the past decade (i.e., between 2012 and 2021). Graphical methods were used to visually display research findings. For the purpose of literature clustering, MAXQDA 2020 software was employed. In total, 118 scientific, peer-reviewed sources were included in the review. Two categories, five clusters, and seven subclusters emerged from the literature set. The results revealed a significant research tendency toward exploring consumer green behavior and consumer purchase intention of food products. The least-explored research themes were focused on consumer intention toward and purchase behavior of clothing, green vehicles, and green personal care products. The review confirmed the growing prevalence of TPB in consumer behavior research aimed at exploring factors preceding behavior.     

Consumers’ subjective and objective consumerism knowledge and subsequent complaint behaviour concerning consumer electronics: a South African perspective

Although there is immense international support for consumer protection, the notion exists that consumer protection can only exist in developed countries with ample fiscal resources and expertise to properly act in the interest of consumers. This conception leaves consumers in emerging and transitional economies in a difficult position as these economies indeed generally lack sufficient funding and the required capacity to educate consumers on their rights. With the South African Consumer Protection Act that came into effect in 2011, South African consumers can now claim to be among the best protected consumers in the world. However, many consumers are still not aware of their consumer rights, and do not have the necessary knowledge to pursue redress when they are dissatisfied. The objective of this research was therefore to explore and describe the relationship between consumers’ knowledge of consumerism (consumer protection) and their consumer complaint behaviour (CCB) concerning their dissatisfaction with a technologically advanced product, in this case, a consumer electronic product. This study attempts to differentiate between subjective consumerism knowledge and objective consumerism knowledge and by extension the measures used. In addition, we explored and described the relationship between demographic variables and levels of subjective and objective consumerism knowledge as well as the combined effect of the two types of knowledge on CCB. The findings revealed that the respondents had a reasonable level of subjective consumerism knowledge relative to a low level of objective consumerism knowledge. No significant relationship was found between subjective consumerism knowledge and demographic variables. However, the factors of race, gender and level of income were related to objective knowledge. A higher level of subjective knowledge could be associated with public action. Respondents with reasonable levels of objective knowledge were also better equipped to take private and public action. CHAID (Chi‐Square Automatic Interaction Detection) analysis highlighted that a combination of subjective and objective knowledge was the best predictor of taking public action only and of taking both private and public complaint action. The study has implications for policy makers, consumer protection organisations, retailers and the individual consumer. Our approach to measuring knowledge of consumerism could possibly be applied in other emerging contexts where consumers generally lack awareness of consumer protection.
