This research investigates what consumers in democratized luxury markets value when purchasing luxury items. Nonetheless, these consumers have a limited budget and can not always buy luxury items, yet they are drawn back to these luxury brands. Thus, we use brand engagement in self-concept (BESC) to explain the relationship between these consumers and luxury brands within democratized luxury markets. A conceptualized model of three luxury value dimensions (experiential, symbolic, and functional) is proposed, and 488 cases were gathered through a phone survey. The data were analyzed using partial least squares structural equation modeling (PLS-SEM). The results show that the most critical... 

In the field of supply chain management, understanding the impact of centralized and decentralized decision-making approaches on overall performance is highly important, especially in environments characterized by uncertainty and complexity. This study introduces an innovative approach by incorporating uncertainty into the NK model framework, a model traditionally used for analyzing interdependencies and adaptability in complex systems. Through this, the research examines the dynamic interactions within supply chains under various levels of uncertainty and complexity, offering a more realistic simulation of real-world conditions. The results show that adding uncertainty to the model... 

The aim of this research is to examine environmentally conscious consumer behavior based on the Theory of Planned Behavior, which includes the antecedents of attitude, behavioral control, norm, moral commitment, and psychological factors in the selection of green products. Additionally, it investigates the extent to which this environmentally conscious behavior influences consumers' green purchase intentions. To further analyze green purchase intentions, the study employs the moderating variable of perceived environmental well-being and the mediating variable of need for cognition based on signaling theory. The integration of the Theory of Planned Behavior and signaling theory is utilized to...

Previous Research has extensively investigated ambidexterity in organizational and individual level and evaluated their prescedents and outcomes. These studies have led to an agreement on the positive relationship between ambidexterity in different levels and performance, in dynamic business environments. Unlike before, recent studies in the context of ambidexterity have been focused on the prescedents of ambidexterity in the individual level. However very few studies have empirically investigated the direct relationship between ambidexterity in different levels. In this research we have focused on the relationship between the top manager's ambidexterity and the organizational ambidexterity...

The extant body of literature provides limited coverage regarding the concurrent influence of social responsibility and brand authenticity on both brand expression and adverse consumer behavior. Insufficient attention has been devoted to the correlation between social responsibility and brand forgiveness, as well as mischaracterizations of branding. The interplay of brand and consumer ethnocentrism further serves as a moderating factor in the associations among social responsibility, brand forgiveness, negative discourse, and brand avoidance. Four distinct scenarios, involving the random allocation among distributed companies, were considered: 1. Authentic brand with the presence of social...

Nowadays, customers hold a pivotal role as co-creators of value in service industries. Therefore, companies usually try to encourage customers to interact and co-create value effectively with the company or with each other. However, if a service provider fails to meet customer expectations, service failure occurs and may influence customer evaluations to co-create value. In this situation, companies usually try to redress the problem that happened to reduce their negative perceptions. Research related to the drivers of customers' value co-creation intentions has gained interest in recent years. However, there has not been an integrated view to simultaneously examine the negative role of...

Organizations now take several risks and many factors affect their anticipated performance. The origins of these risk could be external such as Interest rate, political and social changes and change in governing laws and regulations or could be internal such as operational risk, information risks and strategic risks. Enterprise risk management (ERM) as a holistic approach to risk management has been recently used by most organizations. Prior researches on ERM efficiency have inconsistent results and there is a need for more meticulous scrutiny. In this research we examine the role of corporate social responsibility (CSR) as a mediator in the relation between ERM implementation and firm’s... 

Increased globalization and level of complexity of supply chains have made them more vulnerable to environmental disruptions than ever before. However, conventional methods of risk management can not help supply chains in the face of turmoil and disruption, because of unexpected and unfortunate events due to the unpredictability and uncertainty in which they are. They can have irreversible effects on supply chains and even threaten the very existence of members of these chains. In such a situation, the key to the success and survival of supply chain operations is to achieve supply chain resilience. On the other hand, health care supply chains are one of the most important and vital parts of...

Like other industries and research literature, tourism and hospitality have increasingly interpreted and analyzed the vast amount of user-generated content and online reviews to address practical and theoretical issues concerning customer experience and satisfaction. One of the most underdeveloped data-driven research streams in tourism and hospitality is green restaurant research. To address the gap regarding the actual behaviors, perceptions, and anticipations of such restaurants' customers, this study first used a new advanced topic modeling algorithm to identify hidden topics of customer reviews. The result suggests that customers mostly perceive food-related green attributes when it...

The prosperity of online marketplaces depends on their ability to attract and keep sellers besides customers. Due to the lack of research in evaluating the role of sellers in this business model, the study tries to fill this gap through examining the effect of logistics capability on sellers' performance in an online marketplace. Specifically, a research model is developed to evaluate the effect of a customized logistics service, provided by the intermediary, on sellers' performance in the marketplace. In addition, the indirect effect of logistics capability as a mediator is examined on the previous causal link. Strong empirical support for the research model is provided by data from 1546...
