C.; Pereira, Â.; Saraiva, M.; Canas, J. M.; Lopes da Costa, R. Resumo: Purpose This study synthesizes the fragmented literature on the impact of sustainable marketing on firm performance. Despite growing corporate interest, research findings remain contradictory. This paper aims to map the evolution of the field, identify key mediating factors, and propose a novel conceptual framework for understanding how sustainable marketing initiatives can drive business success. Methodology A bibliometric analysis was conducted on a final sample of 55 documents indexed in the Scopus database from 2013 to 2023. The study utilized VOSviewer to map keyword co-occurrences, identifying four central thematic clusters: sustainability, sustainable development, marketing strategy, and green marketing and supply chain management. Findings Results indicate that sustainable marketing generally has a positive long-term impact on performance. However, this relationship is not direct; it is mediated by factors such as green reputation, consumer trust, innovation, and marketing communication capabilities, while being hindered by barriers like greenwashing and implementation costs. Success requires an integrated approach that adapts to regional contexts and consumer environmental awareness. Practical and Research Implications The study proposes a novel conceptual framework that organizes variables into a logical structure linking strategic antecedents, mediating mechanisms, and multi-dimensional outcomes. Practical recommendations include integrating sustainable marketing into traditional strategies, investing in green supply chain management, and ensuring transparency. The research highlights the need for adaptive approaches and suggests future studies incorporate additional databases and empirical testing. Originality/Value This study provides the first bibliometric analysis to synthesize the relationship between sustainable marketing and firm performance into a structured conceptual framework. It integrates fragmented findings from 2013–2023 into a coherent body of knowledge, enriching theoretical understanding by linking results to the Resource-Based View (RBV) and Stakeholder Theory. It offers a new theoretical lens for the field and translates academic findings into practical managerial insights. 2026-01-01T00:00:00Z http://hdl.handle.net/10071/36736 Título próprio: Business models for nature-based tourism companies: The adoption of sustainable requirements Autoria: Abreu, C.; Marques, C.; Pereira, H. G. Resumo: Nature-based tourism is increasingly recognised as a strategic segment within the tourism sector, often dominated by small and family-owned enterprises. Despite its growing relevance, the adoption of explicit, sustainable business models in this segment remains limited, with many firms operating in informal or implicit approaches. Although business models are acknowledged as key mediators of innovation and sustainability, substantial gaps remain in understanding and applying innovative sustainable business model principles within nature-based tourism companies. This study provides novel empirical evidence by examining how these companies integrate sustainability into their business models and by examining the requirements and practices adopted by nature-based tourism entrepreneurs. This study provides novel empirical evidence by examining how these companies engage with the four guiding principles proposed by Breuer et al. (2018) (sustainability orientation, extended value creation, systems thinking and stakeholder integration) and the constraints they face in doing so. Building on these principles, the research explores how sustainability is integrated into existing business models. An exploratory qualitative study based on thirteen semi-structured interviews with Portuguese nature-based tourism entrepreneurs reveals that, although sustainability is widely regarded as essential for competitiveness and long-term resilience, its integration into business models remains uneven and largely intuitive. Environmental aspects receive more systematic attention than social value creation, systems integration or stakeholder collaboration, with progress hindered by limited managerial capabilities, resource scarcity, and weak policy alignment. The study contributes to the literature by clarifying how sustainability principles are operationalised in small tourism enterprises and by identifying structural barriers that prevent their fuller adoption. It also offers practical implications for policymakers and support institutions seeking to strengthen the resilience, competitiveness and sustainability orientation of nature-based tourism systems. 2026-01-01T00:00:00Z http://hdl.handle.net/10071/36716 Título próprio: Beyond funding: How digital finance transforms SME innovation Autoria: Pereira, R.; Omar, M. N.; Gafur, S.; Mussá, N. Resumo: Purpose This study aims to explore the relationship between Fintech integration and innovation performance in French SMEs listed on Euronext Growth Paris and investigates the effects of digital finance adoption on the financial performance of UK-listed SMEs. Design/methodology/approach The French study uses a balanced panel of 186 SMEs from 2022 to 2024, using fixed-effects regression to examine how Fintech adoption (digital credit, payment systems, governance expertise) affects innovation (patent applications). For the UK SMEs, secondary data from 224 firms (2022–2024) is analysed using multivariate regression to explore how digital finance adoption, financial literacy, financial constraints and macroeconomic factors influence profitability and operational efficiency. Findings The results show that Fintech adoption significantly enhances innovation in French SMEs, with governance expertise further boosting this impact. In the UK, digital finance adoption improves profitability by reducing transaction costs and enhancing financial access. Financial literacy moderates the relationship, and macroeconomic factors, like GDP growth, strengthen the positive effects of digital finance adoption on SME performance. Research limitations/implications The focus on publicly listed SMEs limits generalisability to private firms. Future research could explore broader sectors and markets. Practical implications SMEs can leverage Fintech for enhanced innovation and improved financial outcomes, offering insights for managers and policymakers. Social implications The study highlights how Fintech adoption can promote financial inclusion and contribute to more sustainable economic growth by supporting innovation in SMEs. Originality/value This research contributes to entrepreneurial-ecosystem theory by demonstrating Fintech’s role as a strategic capability that drives innovation in public SMEs. It also extends Transaction Cost Economics by illustrating how digital finance adoption reduces transaction costs and enhances financial performance for SMEs in developed economies. 2026-01-01T00:00:00Z http://hdl.handle.net/10071/36685 Título próprio: Unconventional fiscal policies in response to inflation: The Iberian exception in Portugal Autoria: Cerdeira, L.; Vale, S.; Clemente-Casinhas, L. Resumo: The surge in Eurozone inflation in 2022 compelled European governments to implement unconventional fiscal policies. One initiative, the Iberian Exception, imposed a cap on the cost of natural gas used for electricity generation in Portugal and Spain. Using a Bayesian Vector Autoregressive model combined with Bayesian Dynamic Forecasting, we predict a 3.14 p.p. in energy inflation from July 2022 to December 2023. The effect was asymmetric over time, given the structure of contracts and hedging mechanisms within the Iberian Electricity Market. The results highlight the effectiveness of unconventional fiscal policies for managing supply-driven inflationary pressures. 2026-01-01T00:00:00Z
