The purpose of this paper is to compare two brand posts with the different content created by a celebrity (emotional content vs rational content) on Instagram and their effects on users’ willingness to use offline word of mouth (WOM) and electronic WOM (eWOM). The research model also consists of product involvement as the moderator.

Based on the results of the pretest stages, the study included two stimuli, and respondents were presented with two different brand posts (i.e. two manipulated pictures and texts on the Instagram frame). A two-group comparison (positive emotional brand post vs negative rational brand post) between-subjects experiment (n = 214) was conducted.

The results indicate that WOM and eWOM are more affected by a celebrity’s emotional brand post than a celebrity’s rational brand post. Furthermore, both types of WOM are more affected through high product involvement enhanced by a celebrity’s rational brand post than through high product involvement boosted by a celebrity’s emotional brand post.

Managerial implications for social media marketing and Instagram celebrity-based branding are provided. Practical implications are also provided in the form of evidence of how the impacts of two different brand posts on positive offline WOM and eWOM are affected differently through the moderation of product involvement.

The research argues for theoretical implications for the marketing literature on celebrity endorsements. The study also tests one moderating effect on the relationship between brand post content and WOM and eWOM.

El propósito de este trabajo es comparar dos posts de marcas con diferente contenido creado por una celebridad (contenido emocional vs. contenido racional) en Instagram y sus efectos en la disposición de los usuarios a utilizar WOM y eWOM. El modelo de investigación también incluye la implicación del producto como moderador.

Sobre la base de los resultados de las etapas de prueba previa, el estudio incluyó dos estímulos, y a los encuestados se les presentaron dos publicaciones de marca diferentes (es decir, dos imágenes y textos manipulados en el marco de Instagram). Se realizó un experimento entre sujetos (n = 214) de comparación de dos grupos (post de marca emocional positivo frente a post de marca racional negativo).

Los resultados indican que el WOM y el eWOM se ven más afectados por el post emocional de la marca de un famoso que por el post racional de la marca de un famoso. Además, ambos tipos de boca a boca se ven más afectados por la alta implicación del producto potenciada por el post racional de la marca de un famoso que por la alta implicación del producto potenciada por el post emocional de la marca de un famoso.

se ofrecen implicaciones de gestión para el marketing en las redes sociales y el branding basado en los famosos de Instagram. Las implicaciones prácticas también se proporcionan en forma de evidencia de cómo los impactos de dos publicaciones de marca diferentes en el WOM positivo y el eWOM se ven afectados de manera diferente a través de la moderación de la implicación con el producto.

La investigación aporta implicaciones teóricas para la literatura de marketing sobre el patrocinio de los famosos. El estudio también prueba un efecto moderador en la relación entre el contenido de los posts de marca y el WOM y el eWOM.

The purpose of this study is to understand how and why consumers engage in market-shaping activities on behalf of firms.

This study uses a combination of archival, netnographic and interview methods to examine how consumers responded to the entry of Tesla into the U.S. automotive market.

Consumers are driven to engage in supportive institutional work by the culturally resonant ideologies embodied in Tesla’s strategic orientation. This work takes both discursive and practical forms and sees consumers adopting responsibilities typically associated with other actors, including activists and sales professionals.

In developing an account of an understudied phenomenon – consumers’ firm-supportive market shaping – this research extends theorization around institutional work and cultural branding.

Using the theory of planned behavior (TPB) as a theoretical framework, this study investigates individual level psychological determinants of individuals word-of-mouth (WOM) intentions as a way to support corporate social advocacy (CSA).

An online survey (N = 505) using a Qualtrics panel was conducted.

Individuals' attitudes towards WOM, subjective norms, and self-efficacy was positively associated with their positive WOM intention, whereas perceived controllability over WOM behaviors was not associated with WOM intention. Age was negatively associated with WOM intention.

This study is one of the early attempts to test individual level factors in shaping individuals' WOM intention in response to CSA. This study also employed recent TPB argument and tested the role of self-efficacy and perceived controllability on behavioral intentions in the context of corporate communication. The findings of this study offer theoretical and practical insights to corporations when developing CSA campaigns and designing CSA messages.

The purpose of this paper is to explore the impact of sustainable marketing practices of firms on consumers’ attitudinal and behavioral brand loyalty. In addition, this study also aims to explore the mediating effect of brand trust and brand affect on this relationship.

A combination of descriptive and causal research has been used, for which data was collected from 582 respondents and processed using structural equation modeling to establish multivariate relationships. The PROCESS method was used to estimate mediation effects.

A rather valuable insight that emerged is the significant role that brand trust and brand affect play in engendering attitudinal and behavioral brand loyalty among consumers, for firms adopting sustainable marketing practices. Findings revealed that sustainable marketing practices result in enhanced brand trust, which further translates into higher levels of brand affect, thereby leading to attitudinal brand loyalty and further resulting in behavioral brand loyalty. This study also highlights the importance of brand affect in developing enduring behavioral brand loyalty.

Consumers today are changing their consumption habits, preferring to satisfy ideological and symbolic needs rather than just rational needs. So, marketers practising sustainable marketing should aim to leverage brand trust and brand affect to ensure lasting behavioral brand loyalty.

The examination of the effect of sustainable marketing practices on brand-related variables has contributed to a better understanding of the mechanism that underlines the operation of emotion-based enduring loyalty. The vast majority of studies that provided insights about sustainable marketing practices and consumer behavior thereof were dominated by European and American perspectives and very few studies exist with a focus on developing economies. This study attempts to fill this void by exploring the personal care market in India.

The young generation (Gen Z and Millennials) has a different set of values that the brand needs to interpret better. There is evidence of a correlation between luxury brands and sustainability. The purpose of this study is to assess the impact of consumers’ consumption values (functional, experiential, and symbolic) and ethical values (ascribed responsibility) through flow experience (FE) on consumers’ attitudes towards sustainable luxury brands (SLB) in the young generation based on stimulus-organism-response theory.

The research design consists of Studies 1 and 2. Study 1 used a structured questionnaire on a sample of 396 respondents based on the scales of luxury consumption values. For Study 2, the authors collected 30 qualitative responses from the target group (young Indian shoppers who indulge in luxury fashion shopping frequently) via open-ended essays. PLS-SEM was used to test the hypothesised relationship.

As per the results, functional values are the most significant predictors of FE, followed by AR, experiential values and symbolic values. The study also discovered that FE has a substantial influence on the formation of attitudes towards sustainable luxury fashion brands. The qualitative findings were in line with the quantitative findings, except that the respondents have reservations with respect to the authenticity of sustainable initiatives by the brands.

As the young consumer represents the future development of the luxury market, it is crucial to fully comprehend their view with respect to consumption value and AR in an emerging economy like India, which constitutes one of the highest populations of young consumers. The new research framework will also assist luxury brand managers in the formulation of efficient brand marketing strategies for sustainable luxury apparel.

Previous studies have mainly focused on FE in the context of the service industry. There are limited studies exploring the impact of achieving FE in framing the attitude towards sustainable luxury fashion brands. Academic research in the area so far has limited its scope to quantitative and a few qualitative studies, but this study provides a mixed-methods approach in a luxury setting, contributing to the study’s distinctiveness.

The choice of crops to produce at a location depends to a large degree on the climate. As the climate changes and food demand evolves, farmers may need to produce a different mix of crops. This study assesses how much cropland may be subject to such upheavals at the global scale, and then focuses on China as a case study to examine how spatial heterogeneity informs different contexts for adaptation within a country.

A global agricultural economic model is linked to a cropland allocation algorithm to generate maps of cropland distribution under historical and future conditions. The mix of crops at each location is examined to determine whether it is likely to experience a major shift.

Two-thirds of rainfed cropland and half of irrigated cropland are likely to experience substantial upheaval of some kind.

This analysis helps establish a global context for the local changes that producers might face under future climate and socioeconomic changes. The scale of the challenge means that the agricultural sector needs to prepare for these widespread and diverse upheavals.

This paper aims to consolidate the state of research on information behaviour. Regardless of the scholarly surge on information behaviour using numerous models and extended ones, gaps still exist on the development of more pragmatic frameworks that explain and/or predict the information behaviour across different fragmented environmental situations. Therefore, this paper extends technology-organization-environment (T-O-E) framework and synthesizes different research positions into a multi-dimensional framework that assists small and medium enterprises (SMEs) to understand their information behaviour and to make informed decisions on the adoption of emerging information communication technology (EICT).

This study deployed an inductive approach; data were generated from unstructured and semi-structured interviews with 20 participants drawn purposively from Luton directories.

This study developed a more integrated framework underpinned by T-O-E framework, which helped to identify how EICT adoption is critically shaped by perceived information need, information sources selection and the factors determining information source selection.

Qualitative research is normally subjective, inductive, interpretive and limited on the sample used. However, because of the limited number of interviews used, as well as industry-specific nature of the study, the generalization of the framework and the findings will be difficult, hence, the need to test the framework on a broader population and cross-context testing.

The T-O-E framework is extended to Expectancy (T-O-E-E) to provide a more robust insight into information behaviour of SMEs from a multi-dimensional perspective. It also offers a more analytical framework for exploring critical issues identified and demonstrates the capacity to provide a reliable explanation to the findings. Further, it serves as a tool for assessing the benefits or challenges of SMEs information behaviour especially on the EICT adoption decision.

This study employed self-determination theory (SDT) and the “Motivational affordance–Psychological outcomes–Behavioral outcomes” framework to investigate the relationship between gamification features and knowledge-sharing behavior in online communities.

A theoretical model was tested with 281 Chinese users from an online social question and answer (Q&A) community. Partial least square structural equation modeling was applied to analyze the data.

The empirical results revealed that competence mediated the effects of immersion and achievement-related gamification features on knowledge sharing. Moreover, relatedness mediated the effects of immersion, achievement and social-related gamification features on knowledge sharing.

This study was conducted on a Chinese Q&A platform, and the results may not be generalizable to other cultures or service providers with different goals.

The study's findings indicate that gamification could serve as an effective toolkit for incentivizing and promoting knowledge sharing in online communities. The findings thus provide strategic insights for administrators of online communities seeking to leverage gamification designs to encourage user participation in knowledge-sharing activities.

Research on the role of gamification in promoting knowledge sharing has been limited in scope and has focused on tourism comment communities. Little evidence exists on the effect of gamification within social Q&A communities. Further, the finding of gamification's positive role in motivating knowledge sharing indicates the need for the knowledge-sharing field to focus on contextual factors.

The purpose of this study is to investigate the structure and dynamics of academic articles relating to public procurement (PP) in the period 1984–2022 (up to May). The researchers also intend to analyse how this knowledge domain has grown since 1984.

A bibliometric analysis was carried out to examine the existing state of PP research. Based on 640 journal articles indexed in the Scopus database and written by 1,247 authors over nearly four decades, a bibliometric analysis was conducted to reveal the intellectual structure of academic works pertaining to PP.

Findings reveal that PP research from Scopus has significantly increased in the past decade. Major journals publishing PP research are International Journal of Procurement Management, Journal of Cleaner Production, Journal of Purchasing and Supply Management and Public Money and Management. Results also indicate that authors’ cooperation network is fragmented, showing limited collaboration among PP researchers. In addition, results suggest that the institutional collaboration network in PP research mirrors what is commonly referred to as the North–South divide, signifying insufficient research collaboration between developed and developing countries’ institutions. According to the co-occurrence keyword network and topic modelling, PP revolves around five main themes, including innovation, corruption, sustainable and green PP, PP contracts and small and medium enterprises. Based on these results, several directions for future research are suggested.

This paper provides an increased understanding of the entire PP field and the potential research directions.

To the best of the authors’ knowledge, this study is the first-ever application of bibliometric techniques and topic modelling to examine the development of PP research since 1984 based on scholarly publications extracted from the Scopus database.
