    Evaluation of circular economy indicators seeking sustainable development goals

    Full text link
    To tackle climate change, resource scarcity, and environmental degradation, the circular economy (CE) is gaining popularity as a key tool for promoting sustainability by harmonising societal, economic, and environmental needs and contributing to global sustainable development goals. This research aims at determining which circular economy indicators most significantly impact the sustainable development goals (SDGs) in European Union (EU) countries. Panel regression analysis was used to determine which circular economy indicators most significantly impact the Sustainable development goals index across the EU countries. In this study, five separate panel regression models were developed, each representing a pillar of the European Union’s CE framework: production and consumption, waste management, secondary raw materials, competitiveness and innovation, global sustainability and resilience. Based on the results, CE indicators have varying effects: material and consumption footprint, generation of municipal and packaging waste per capita, the recycling rate of municipal waste, circular material use rate, trade in recyclable raw materials as well as persons employed in the circular economy sector and material import dependency are associated with the improvement of the SDG index, while recycling rate of WEEE (waste of electrical and electronic equipment) and greenhouse gas emissions are associated with the decrease of the SDG index. These outcomes are often linked to economic growth and the expansion of green technologies, which are essential for a more sustainable future. This research explains the linkage between the circular economy and its contribution to achieving the SDGs in EU countries. It enables policymakers, businesses, and other stakeholders to recognise the significance of CE practices in attaining sustainable development. The research outcomes can guide the development of CE policies, prioritising impactful areas for countries dedicated to achieving sustainable development through CE practices

    A proposal of a relative weighted online 5-star rating system as a way to mitigate online reviews biases

    Full text link
    Online ratings and reviews can be considered an electronic word of mouth regarding the quality of goods, products, or services. Reviews provide crucial information for customers, therefore significantly influencing their behavior, and they enable feedback to businesses from their customers, increase visibility, drive sales, help in developing a brand and building trust and reputation among consumers. However, the current 5-star rating system currently used on many Internet platforms such as Amazon or TripAdvisor suffers several drawbacks (biases) such as sentiment bias, polarization bias, non-discrimination bias, or vocal minority-silent majority bias. Therefore, the aim of the paper is to propose a new (weighted) relative 5-star rating system which takes into account reviewers’ history (in the form of the average and variance of the past reviews) and transforms absolute aggregate ratings into relative ones, thus providing less biased information for consumers and businesses. In particular, the proposed system reduces sentiment bias and non-discrimination bias. Moreover, the proposed approach enables to reduce the influence of ratings made by bots or dishonest evaluators-humans. The real-world application of the proposed approach dealing with ratings of selected attractions in Madrid area is provided as well

    Circular economy practices, green innovation and financial performance: The moderating role of big data analytics

    Full text link
    Environmental pollution and resource degradation have prompted researchers and policymakers to seek solutions. Circular economy practices (CEP) can help enterprises reduce emissions into the environment and move towards sustainable development. CEP has been studied widely in developed countries but less studied in developing countries due to the limited application of CEP in enterprises and the limitation of data. This paper aims to analyse the effect of CEP on financial performance, including revenue, profit and ROA. We also analyse the mediating role of green innovation and the moderating role of big data analytics in the relationship between CEP and financial performance. The natural resource based view (NRBV) theory is used to explain the relationship between variables and establish research hypotheses. We collected data from 413 Vietnamese manufacturing enterprises and used the regression method to test the research hypotheses. The results show that CEP positively impacts financial performance through the mediating role of green innovation. Besides, big data analytics also positively impacts the relationship between CEP and green innovation. In addition to the main results above, digital transformation positively impacts financial performance, but quality management practices do not affect financial performance. The research results are empirical evidence for enterprises considering implementing CEP to move towards sustainable development

    Make ads skippable or not: The impact of ad type on brand recall, salience and conversion rate

    Full text link
    In today’s world, people are using digital platforms more than ever to communicate with friends, network, shop, learn and more. The average time spent on these platforms is increasing. Companies are naturally reflecting this fact in order to reach as many people as possible through these platforms and their advertising messages. However, users are constantly bombarded with advertising messages that fragment their attention. It is, therefore, important to study the effects of different types of video advertising, with or without skipping, on consumers’ purchasing decisions and to create ads that perform better but do not distract the audience. Therefore, the aim of this paper is to investigate the effect of skipping ads in terms of brand memorability and brand salience on subsequent conversion performance in an e-commerce store. The results of the study show that consumers achieve lower brand recall and conversion rates when shown a non-skippable ad than a skippable ad. On the other hand, while skippable ads are associated with higher levels of actual brand recall, from a more holistic perspective, the non-skippable ad type is better suited to increase brand salience, which appears to be more important for subsequent future purchase execution at the retailer

    Analysis of circular strategies: A case study of the food processing industry

    Full text link
    This research investigates the implementation of the circular economy in the Galician canned fish and seafood sector. This sector is crucial, producing 225,000 t annually and representing 75% of Spain’s total production, significantly contributing to the regional economy and employment. Moreover, this industry significantly contributes to the regional economy employing around 12,000 people. Using the PESTLE methodology, the study systematically and holistically examines the most relevant systems and actors in the sector. The analysis is complemented by a SWOT analysis, enriched through brainstorming sessions with 24 industry experts who evaluated and scored each factor’s importance from 0 to 1. From the analysis of the external environment of the circular strategy that the industry is exposed to and does not control, economic uncertainty is identified as the main threat (0.8) and technological innovation as the main opportunity (0.9). The internal environment analysis, influenced by the industry’s current situation, identified the main weakness of the circular strategy as high implementation costs, and the main strength is institutional and regulatory support (0.9). The results highlight significant institutional and regulatory support, availability of public subsidies, and strong technological and research capabilities as major strengths. However, the sector faces challenges such as dependence on public funding, high implementation costs, and a lack of qualified workforce. Opportunities include growing demand for sustainable products and technological innovation, while threats encompass economic uncertainty and global competition. The conclusions emphasize the need for strategic management of these factors to ensure the successful adoption of circular economy practices. Specifically, enhancing collaboration between the public and private sectors, increasing investment in innovation and workforce training, and leveraging favorable legislation are crucial for improving the sector’s sustainability and competitiveness. By strategically managing these elements, the Galician canned fish and seafood sector can not only enhance its environmental sustainability but also achieve greater economic resilience and market competitiveness. This comprehensive approach ensures that the sector can effectively transition to a circular economy, benefiting both the environment and the industry’s long-term viability

    The relationship between implicit moral hazard, corporate governance, and bank lending behavior

    Full text link
    Environmental, social, and governance (ESG) development has indeed changed the original economic operation status through diversified methods. The banking industry, especially under the guidance of ESG, reminds the banking industry that it should focus on regulatory conditions such as lending objects with ESG operating characteristics. In terms of corporate governance, the banking industry needs to adopt high self-management standards for business development. This paper uses the panel threshold model to measure the regional moral hazard of 30 firms in the Taiwan bank industry from 2007 to 2018. The research shows that banks with high regional loan concentration ratios have evidence of moral hazard and a significant asymmetric effect in the regional loan concentration ratio in the bank industry. Based on this, the bank’s high regional (NPL ratio) is used to measure the level of the bank’s credit risk and quality of outstanding loans, which requires strengthening loan quality, the optimum concentration of loan weight, promoting the establishment of the effectiveness of the ownership structure and enhancing the development of management ability. Due to Taiwan’s banking industry’s overly competitive business environment, loan concentration and moral hazard lending practices have emerged. There is an apparent correlation between the development of the banking industry and an extremely competitive business environment. Therefore, how to have healthy competition in the banking industry instead of vicious competition is worth learning from other countries. This paper argues that creating a competitive banking environment is crucial. To target loan recipients, the banking industry should leverage its business expertise, integrity, and business ethos in line with international trends, such as ESG development trends. Regarding corporate governance, banks should be able to use equity structures, compensation system management, and internal management measures to establish more competitive professional bank

    From innovativeness to sustainable transportation: Managing electric vehicles adoption in a circular economy progressor

    Full text link
    Although numerous studies have explored the electric vehicles (EVs) adoption, the theory of reasoned action (TRA) is underutilized, while the role of consumer innovativeness in predicting purchase intent and behavior remains unclear. This study focuses on the interplay among attitude towards EVs, subjective norm, consumer innovativeness, purchase intention and actual behavior. A structured survey was applied in 2024 to collect data, and a sample composed of 212 respondents from the United Arab Emirates was properly balanced across various characteristics. TRA was extended using the consumer innovativeness construct, which resulted in a new hypothetical model. Once evidence was provided for both validity and reliability of the measures, the hypotheses were tested. Structural equation modelling (SEM) results show that subjective norm does not have significant direct effects on purchase intention, while the consumer innovativeness affects attitude towards EVs. While both attitude towards EVs and consumer innovativeness appear to be direct predictors of purchase intention, attitude towards EVs played a significant mediating role in a relationship between consumer innovativeness and purchase intention. The results of logistics regression revealed that purchase intention directly affects purchase behavior. The paper contributes to significant theoretical and practical implications, which are further discussed
