This study aims to analyze the relationship between workplace ostracism and knowledge hoarding. The study also proposes a mediational role of organizational climate in the relationship between workplace ostracism and knowledge hoarding.

The procedure used in the study is a systematic literature review covering workplace ostracism, knowledge hoarding and organizational climate from 1986 to 2021. The studies were explored using keyword searches such as “Workplace ostracism”, “Knowledge hoarding” and “Organizational climate” from the selected databases, namely, Scopus, Web of Science and Google Scholar.

The systematic review of 146 articles found most studies suggesting that workplace ostracism affects employees’ personal and professional relationships and is a precursor to knowledge hoarding behaviours. The workplace ostracism–knowledge hoarding relationship has a logical explanation as knowledge hoarding is often perceived as counter-normative, which can reduce the performance of a hoarder, leading to behaviours such as ostracism and expulsion. The review proposes that organizational climate plays a significant role in improving the workplace ostracism and knowledge hoarding relationship. The study introduces some fundamental propositions towards the development of a model for future research.

The study attempts to uncover a series of relationships between workplace ostracism, knowledge hoarding and organizational climate, which may enhance academic discussion and offer clarity to the conceptualization of these two fields.

This paper aims to review the relationship between per capita income and aggregate emission in an economy populated by rational agents. According to the environmental Kuznets curve (EKC) hypothesis, pollution–income relationship is an inverted U-shaped curve. This paper aims to derive that relationship in an endogenous way and extends the relevant literature in an important way.

This paper formulated a general equilibrium model of homogenous population with identical tastes and preferences. Production side is modelled with firms operating in a monopolistically competitive environment. The approach is modelling the economy in an analytical way so that closed form solutions can be achieved. Model simulations have also been performed to get a clear view of results.

This study shows that increasing returns to scale in abatement technology ceases to be a sufficient condition for the generation of the EKC hypothesis. The general equilibrium structure of the model allows studying the endogenous evolution of income, emissions and prices of the abatement goods in a unified setting.

The paper is novel and original in nature. The results are new in the literature. These results extend and generalise the previous research work in this area in an important way. The sufficient condition that is obtained in this study limits the applicability of EKC in an otherwise identical economy as used in previous literature. Therefore, this paper adds value to the ongoing research related to EKC.

The purpose of this paper is to examine the impact of user gender, celebrity gender, and celebrity-user gender congruity on celebrity personality-user personality (CP-UP) congruity, and consequently, brand purchase intention (BPI). Additionally, it delves into the mediating roles of CP-UP congruity and brand personality-celebrity personality (BP-CP) congruity.

A survey research entailing a sample of 709 adult consumers was used to test the framed hypotheses by means of a structural equation modelling.

The results indicate that while celebrity and user gender have a significant positive effect on CP-UP congruity, celebrity-user gender congruity has a negative effect. The study shows a partial mediation of CP-UP congruity in the relationship between gender congruity and BP-CP congruity. Furthermore, BP-CP congruity is shown to have a full mediation effect on the relationship between CP-UP congruity and BPI.

Consistency of the results of this study may be corroborated by employing other methods to estimate congruity scores. Also, the results of the present study may not be generalisable across different product classes with varied consumer involvement.

The findings have major implications for practitioners in understanding the significance of BP-CP congruity among celebrity-user-brand in the formation of purchasing intentions. The results of the study suggest a better CP-UP congruity when the gender of the celebrity is opposite to the gender of the user. This result questions the generalisability of the similarity theory that exhorts a prospect’s customary identification with a spokesperson of her/his own sex and further reinforces the selectivity hypothesis that indicates different information processing of males and females while they make judgements. Therefore, it might be a good idea for advertisers targeting female audiences to employ male celebrities in certain endorsements.

This is the first study that tests for the mediation effect of CP-UP congruity in the relationship between gender congruity and BP-CP congruity, and that of BP-CP congruity in the relationship between CP-UP congruity and BPI.

This study aims to examine the influence of gameful experience (GAMEX) on customer brand engagement in the context of e-tailing. Drawing on the self-determination and social learning theories, the authors have developed a comprehensive model incorporating cognitive, emotional and behavioral factors leading to brand advocacy and re-visit intention for the retail website.

The data for this study were obtained from 715 customers across various e-tailing websites. This research uses both quantitative method (partial least squares structural equation modeling − PLS-SEM) and qualitative method (fuzzy set qualitative comparative analysis − fsQCA) to investigate the relationship between GAMEX and customer brand engagement in the e-tailing context, with a focus on the long-term outcomes of brand advocacy and re-visit intention.

The PLS-SEM results indicate a significant impact of GAMEX on customer brand engagement. In addition, the findings reveal the moderating role of fear of missing out, internet self-efficacy and technoeustress in the association among GAMEX, customer brand engagement, brand advocacy and re-visit intention. The findings from fsQCA support the results obtained from PLS-SEM and reveal four configurations for brand advocacy and five configurations for re-visit intentions.

This research evaluates the impact of GAMEX on customer brand engagement using a mixed-method approach involving qualitative and quantitative procedures. This study offers valuable insights into the design of gamified marketing activities and current practices for fostering greater engagement.

Extant literature shows that gamification is an effective tool for enhancing customer brand engagement. However, there is a need for a structured review of the literature on how and to what extent gamification fosters customer brand engagement. This hybrid literature review synthesizes extant research on gamification and its impact on customer brand engagement.

The study is based on 45 articles drawn from 33 journals from the Scopus database. This article conducts a systematic review of theory, context, characteristics and methods employed in extant research, identifies contemporary themes and presents future research avenues. It also conducts a bibliometric analysis to identify the most prominent journals, authors, articles and themes.

This review identifies various patterns and trends of psychological capital research, and it unfolds four major themes – gamification and customer engagement, gamification and e-marketing, gamification and sustainable marketing and gamification and customer experience.

This review offers key insights into managerial implications.

It is one of the first endeavors to conduct a structured review of research related to gamification and customer engagement. It presents a conceptual framework that shows the relationships between gamification and customer engagement. This systematic review offers several future research agendas to spur scholarly research and presents key insights into the process of gamification in marketing to enhance customer brand engagement.

Earlier studies establish a positive relationship between volatility index (VIX) and the stock index returns. These studies are mainly restricted to developed markets and research in this regard in emerging markets is scarce. The purpose of this paper is to fill this gap.

The paper studies the direct and cross‐sectional relationship of India VIX in relation to three important parameters: viz., stock beta, market to book value of equity and market capitalization. The paper constructs value weighted portfolio sorted on the basis viz., stock beta, market to book value of equity and market capitalization. The paper employs three‐factor multiple regression to find out the results.

The paper finds that India VIX has a positive and significant relationship with the returns of the value‐weighted high‐low portfolios sorted on the basis of the above parameters. The paper examines the behavior of India VIX in the presence of the above two parameters. The India VIX yields a positive and significant relationship with the above sorted portfolio returns.

India VIX was recently introduced in November, 2007 and therefore the research is expected to suffer from small sample bias.

The findings suggest India VIX is a distinct risk factor capable of predicting the price discovery mechanism of the market.

In the rapidly expanding emerging markets the introduction of Volatility Index is a recent phenomenon. Research in this regard is scarce, particularly in the area of finding predictive ability of the Volatility Index. This research is in this direction and would definitely help the market regulators and policy‐makers with their understanding of the market and market direction. It would help them to correct the market imbalances and avert crisis, which has been recently witnessed.

The purpose of this paper is to analyse of structures made in rock mass with multiple intersecting discrete discontinuities such as joint, fault, shear plane.

In this study, a numerical method is proposed for analyzing multiple intersecting joints with varying dip angles, spacing and roughness in eXtended Finite Element Method platform. A procedure is also outlined to treat excavated enhanced (jointed) elements for analysing the effect of excavation sequences.

The proposed method is compared with the existing interface element methods (Phase-2 model) by considering the stress and displacement distributions of a multiple intersecting jointed rock sample under uniaxial loading conditions. A circular tunnel in rock mass having intersecting joints is also analyzed for the distribution of mobilised friction angle of joints and results are compared with a derived analytical solution.

Nucleation and propagation of cracks should be incorporated into the proposed framework in future studies.

The proposed method is a useful tool for rock mechanics and geotechnical engineering problems to analyse strength and deformability of jointed rock masses.

The paper enumerates concepts and detail implementation procedures of the proposed method in three-noded triangular elements. The intersection of joints is formulated in such a way that no additional (junction) enrichment is required in model. The method has been improved for inclusion of Dirichlet and Neumann boundary conditions to be applied in the enhanced part of a problem domain.

The effectiveness of microfinance institutions (MFIs) in rescuing poor borrowers from “clutches of” moneylenders has been a much-debated topic over the past few decades. This paper aims to contribute by presenting a model of competition between a socially motivated MFI and profit-maximizing moneylenders when market segmentation exists.

A principal–agent model is used to characterize equilibrium conditions under scenarios where only moneylenders operate, only MFI operates and when both co-exist to pose comparative results effectively.

The authors find unambiguous benefits arising when a welfare-maximizing MFI enters the market. However, there are benefits to having local agents like moneylenders on the ground who also have informational advantages.

To the best of authors’ knowledge, this study is the first to evaluate the competition between MFI and moneylenders under the framework of captive and noncaptive segments with a mandatory savings requirement.
