In the modern competitive scenario, all companies seek to understand how to achieve success. One of the keys to conquer/maintain market shares is sustainability, which is a hot topic of numerous studies that have focused on its use as a solution to obtain social, environmental, economic, and cultural benefits. To this end, the present work aims to identify the variables able to guide consumers towards the choice of sustainable restaurants through the conceptual extension of a theoretical model known in literature as Theory of Planned Behavior (TPB). The authors propose an Extended Theory of Planned Behavior (ETPB), consisting of seven variables: attitude; subjective norm; perceived behavioral control; perceived usefulness; curiosity; behavioral intention; and behavior. The authors used a quantitative approach based on the test of a Structural Equation Model (SEM). Overall, 1023 questionnaires were analyzed. The results of the analysis provided empirical evidence for the hypotheses formulated suggesting that attitude, subjective norm, perceived behavioral control, perceived usefulness, and curiosity affected the consumers’ behavioral intention to prefer sustainable restaurants and that behavioral intention affected their actual behavior. Based on what emerged from the analysis, the work could be understood as a useful tool for scholars and practitioners, suggesting interesting theoretical and managerial implications. In fact, on the one hand, it contributes to the enrichment of scientific literature related to the factors triggering human choices, and, on the other, it helps maximize the success of the restaurants by highlighting the levers to be actioned to improve business performances. However, the paper presents a main limit, linkable to the fact that, whilst the use of questionnaires represents an advantage in terms of sample size, on the other hand, it does not allow us to go deeper in understanding the reasons why people prefer restaurants that adopt sustainable practices.

In recent times, the concept of sustainability has gradually taken on a leading role,\ud particularly because of its potential ability to influence consumers’ view and, consequently, their\ud buying choices. Based on this consideration, the work, by means of an empirical analysis, pursues\ud two research questions: (i) is it possible to imagine a theoretical model in the fashion world able\ud to show whether “importance”, “expectations” and “social influence” effectively affect consumers’\ud willingness to reward a sustainable fashion brand via their purchasing behavior? and (ii) how much\ud are consumers willing to pay to get a sustainable item of clothing? In order to answer these two\ud research questions, a Multiple Linear Regression Model is tested, which offers an interesting result:\ud consumers attach little relevance to the importance accorded to a brand’s sustainability, since they\ud orient themselves on the basis of their expectations and their own group’s thoughts. Another finding\ud is that consumers state that they are willing to pay a price not higher than 20% to get a sustainable\ud item of clothing. However, the paper presents two limitations, which are linked to the use of the\ud questionnaire for the understanding of the respondents’ opinions and to the small reference sample,\ud composed of 271 people with a high level of education

Purpose The purpose of this paper is to provide a better understanding of the reasons why people use or do not use carpooling. A further aim is to collect and analyze empirical evidence concerning the advantages and disadvantages of carpooling. Design/methodology/approach A large-scale text analytics study has been conducted: the collection of the peoples’ opinions have been realized on Twitter by means of a dedicated web crawler, named “Twitter4J.” After their mining, the collected data have been treated through a sentiment analysis realized by means of “SentiWordNet.” Findings The big data analysis identified the 12 most frequently used concepts about carpooling by Twitter’s users: seven advantages (economic efficiency, environmental efficiency, comfort, traffic, socialization, reliability, curiosity) and five disadvantages (lack of effectiveness, lack of flexibility, lack of privacy, danger, lack of trust). Research limitations/implications Although the sample is particularly large (10 percent of the data flow published on Twitter from all over the world in about one year), the automated collection of people’s comments has prevented a more in-depth analysis of users’ thoughts and opinions. Practical implications The research findings may direct entrepreneurs, managers and policy makers to understand the variables to be leveraged and the actions to be taken to take advantage of the potential benefits that carpooling offers. Originality/value The work has utilized skills from three different areas, i.e., business management, computing science and statistics, which have been synergistically integrated for customizing, implementing and using two IT tools capable of automatically identifying, selecting, collecting, categorizing and analyzing people’s tweets about carpooling.

Purpose.\ud The purpose of this paper is to show the relevance of the interest in sharing the common purpose and in searching for a common survival of emerging eco-system (ES) as an entity that “is not” but emerges by the viable actors interaction.\ud \ud Design/methodology/approach.\ud This conceptual paper contributes to the research by defining the ES building on the contributions of SD logic and viable systems approach (VSA), with a particular focus on the VSA perspective.\ud \ud Findings.\ud An ES emerges as a viable “system of systems” by an observer’s interpretation of the simultaneous interactions between different viable actors/systems that are sharing a common purpose (the survival of the ES), exchanging resources following a viable value co-creation model. Each actor/system could represent a level of quality of belonging to the ES looking for the opportunity to be resonant with the ES.\ud \ud Research limitations/implications.\ud The ES features and the role of each actor inside could be deepened through different theoretical perspectives and the same VSA to the ES could be reached with empirical explorations.\ud \ud Practical implications.\ud Understanding the nature of the ES, the practitioners are able to explain better their position in relation to partners and competitors. It is possible to be a part of several emerging ESs looking for the will to contribute to the ES’ survival and to the sharing of the purpose of the interactive systems/actors. In a medium and long run, the measure of the resonance is useful to understand the quality in interaction.\ud \ud Originality/value.\ud The work provides a definition of the ES and the actors inside focusing on the perspective of VSA, by integrating the concept of viable value co-creation and solidarity-based logic; in particular, the concept of Centro Commerciale Naturale is used to show the emergence of the ES in a relational context generated by the interaction between city, service and retailers in a city center
