Purpose: The aim of the present study is twofold. First, it measures Facebook users’ experience in a holistic way by taking into account the various dimensions of Facebook experience (i.e. entertainment, flow, escapism, challenge, learning, socializing and communitas); second, it tests the effects of these dimensions in relation to consumers’ brand engagement on Facebook. Design/methodology/approach: Two online surveys were conducted using self-administered questionnaires. Respondents were recruited through the snowball sampling technique. Findings: The findings suggest that the different experiential elements of Facebook usage have varying effects on the two brand engagement factors (consuming and contributing) on Facebook. Specifically, the passive element (consuming) is positively influenced by the dimensions of flow and communitas (i.e. feelings of belongingness), while escapism is found to be a negative predictor. The active element of engagement (contributing) is positively affected by dimensions such as entertainment, flow, socializing and communitas. Practical implications: Brand managers should design Facebook pages for their brands that entertain and immerse consumers, while enabling them to socialize and bond with others to increase levels of consumers’ engagement with brands on Facebook. However, brand managers should be cautious regarding the fantasy experience (escapism) offered by their Facebook pages, as this can distract consumers from the content of the brand page. Originality/value: To date, most studies on Facebook usage have been conducted under the uses and gratifications framework, while the various elements that comprise Facebook users’ experience have not received sufficient attention in previous conceptualizations of Facebook experience. In addition, the present study enhances the research by examining consumers’ brand engagement on Facebook as a potential consequence of the various Facebook experience dimensions.

Purpose: The purpose of this paper is to investigate the impact of store characteristics (i.e. product availability, product quality, store layout, employee politeness, décor, music, lighting, and aroma) on the various dimensions of in-store leisure shopping experience (i.e. hedonic, flow, escapism, challenge, learning, socialising, and communitas). Design/methodology/approach: In order to achieve the study’s objectives, a quantitative on-site survey was conducted. Respondents were interviewed upon exiting fashion retail stores. Findings: Findings indicate that not all store characteristics impact the various dimensions of experience in the same way. Product quality and in-store music were found to be the most important in-store characteristics that affected the majority of experience dimensions. Other important store attributes that emerged were store layout and ambient scent. Conversely, product range actually had a negative impact on in-store experience. Practical implications: By orchestrating the most influential in-store characteristics, fashion retailers could be delivering unique in-store experiences to their customers. This research shows that they would benefit from designing experiential strategies that focus on merchandise quality, price, and availability while simultaneously carefully managing ambient (music and scent) alongside design factors (store layout and décor). Careful consideration should be paid to merchandise variety in order to avoid potentially negative effects on customers’ shopping experience. Originality/value: Until now most studies that document the relationship between store elements and shopping experiences have examined the effects of store characteristics on a limited number of experience dimensions. This study adds to the body of research into in-store leisure shopping experience in two ways: by shedding light on its multi-dimensional nature, and by analysing the effect of the different store elements on the various components of the in-store experience.

Purpose: This paper aims to examine consumer reactions during product-harm crises by measuring the impact of perceived risk, blame and trust on consumer purchase intentions. Moreover, the role of perceived crisis severity is examined as affecting the three main endogenous variables of the conceptual framework. Design/methodology/approach: The study uses the real-scenario approach for empirically testing the proposed conceptual framework. Participants were called to assess the story of a defective product (i.e. a soother that was recently recalled). Findings: Results of the equation modeling demonstrate that perceived severity significantly influence trust and blame while it does not affect perceived risk. In addition, trust, blame and perceived risk notably affect purchase intentions. Practical implications: Based on the study’s results, companies could implement appropriate strategies for reducing the negative consequences of a product-harm crisis. Originality/value: The paper presents four key originality traits: Crisis management from the consumer perspective has received little attention. The relationship between trust, perceived risk and purchase intentions has not been explored in the crisis management field. Attribution of blame is a new variable added to the perceived risk-trust-purchase intention model. Perceived severity is examined as a moderator affecting the main endogenous variables of the conceptual framework.
