The first Austrian school was preoccupied with the nature of capital, its time dimension, and the necessity of interest. The second school also focused on economic dynamics, but with an orientation toward issues related to entrepreneurial activity as well as the use of information and knowledge in economic evolution. The third Austrian school, which was organized around Karl Menger's mathematical colloquium in Vienna, clarified the necessary and sufficient conditions for static and dynamic economic equilibriums. In addition, it created the foundations of economic game and negotiation theories.

This paper aims to examine consumer preference for ethical fashion products by focusing on the importance of animal welfare attribute. To explain the attitude-behavior gap, this research proposes to explore the costs and sacrifices associated with the adoption of responsible behaviors.

To analyze in which manner the animal welfare attribute impacts the consumer preference, the authors carried two quantitative studies in the Italy context. The first one (n = 224) proposes to measure the importance of this attribute in the case of luxury vs accessible fashion. The second study (n = 101) examines how the attention given to animal welfare information could vary between prosocials and proselfs. Conjoint analyses that consider “proportion of real fur”; “information about animal treatment” and “price” attributes have been realized. To take into account the individuals characteristics, cluster analysis helped to identify different profiles of consumers.

The results reveal that even if consumers continue to prefer products made entirely from animal fur, they are sensitive to the information on the animal treatment conditions. Also, the animal welfare is not the most important criterion in explaining preference for a fashion product. This result varies, however, regarding the consumers’ social value orientation. Individuals with a high level of prosocial values give more importance to the animal welfare attribute and are less reluctant to the reduction of the proportion of real fur in the clothes. Proself consumers associate a higher sacrifice with the consumption of animal-friendly fashion products.

This research enriches the limited literature on the consumers’ response to animal-friendly products. By considering the consumers’ social value orientation, it provides a better understanding of the attitude-behavior gap in animal-friendly fashion consumption. However, further studies should focus on the way of adapting communication on eco-products to the consumer profile. Moreover, it seems interesting to explore how the integration of innovative environmentally friendly materials can be accepted by the target. Replicating this research with representative consumer samples from different countries is also necessary.

From a practical point of view, this research offers implications for managers operating in fashion apparel industry by giving insights on the consumers’ preference for animal friendly fashion.

This study gives recommendations to help convincing consumers about the importance of animal welfare attribute and to increase their preference for animal-friendly fashion products.

Despite the extensive use of animal fibers, fur and skins in the production of textiles, the few researchers who have shed the light on the consumers’ response to animal-friendly products have considered mainly the case of food. Also, the marketing literature gives little explanation of the attitude-behavior gap in ethical fashion consumption. By examining the consumers’ social value orientation, this study provides a better understanding of this gap.

The literature that is presently available on sustainable supply chain management (SSCM) combining optimization and industry 4.0 techniques falls short in its depictions of the recent developments, budding pertinent areas and the importance of SSCM in the growth of industrial economies around the world. This article's main objective is to analyze current trends, highlight the latest initiatives and perform a meta-analysis of the literature that is currently accessible in the SSCM area with a special focus on optimization and industry 4.0 techniques. The paper also proposes a conceptual framework that will assist in illuminating how the ideas of optimization and industry 4.0 may contribute to realizing sustainability in supply chains.

The proposed study systematically reviews 85 research publications published between 2010 and 2022 in referenced peer-reviewed journals in diverse fields, including engineering, business and management, services and healthcare. Numerous categories are considered throughout the examination of the literature, including year-wise publications, prominent journals, type of research design, concerned industry and research technique used.

The study demonstrates a deeper comprehension of the literature in the field and its evolution throughout numerous industry sectors, which is helpful for both practitioners and academics. The results from the content analysis highlight various future research opportunities in the domain.

This is one of the first research articles that have attempted to establish, analyze and highlight the current trends and initiatives in the SSCM domain from an optimization and industry 4.0 techniques viewpoint. The cluster-based future research propositions also enhance the novelty of the study.
