Abstract

Abstract This paper reports the findings of a bibliometric study examining how scholarly literature has approached the relationship between the informal economy and competencies – two themes that, while individually well-researched, have rarely been studied together in a systematic way. Working with 1,586 unique publications retrieved from Web of Science (WoS) and Scopus, we analysed publication trends, collaboration networks, and thematic structures spanning the period from 1975 to early 2025. The data reveal that research output in this area grew slowly for decades before accelerating sharply after 2001, with a particularly pronounced increase following 2020, a shift we attribute, at least partly, to the disruptions of the COVID-19 pandemic, the expansion of digital tools, and the growing emphasis on sustainability in international policy. European and Asian institutions account for the largest share of publications, though African and South Asian contributors are becoming increasingly visible. Thematic mapping identifies core research clusters centred on labour markets, education and training, gender issues, governance, and digital transitions. Despite the increasing visibility of skills-related topics, the explicit connection between competencies and informal economic activities remains underexplored. This gap matters, as without more integrated analytical frameworks, it is difficult to understand how skills shape participation in informal work or facilitate transitions to formal employment, particularly in economies undergoing rapid and uneven socioeconomic change.

The role of clusters in fostering entrepreneurship: A bibliometric study of global research trends

This paper conducts a bibliometric exploration of research linking two concepts i.e. clusters and entrepreneurship, a domain that has expanded steadily over the past thirty years. Using 155 peer-reviewed articles sourced from the Dimensions database (1996–2025), the study applies the SPAR-4-SLR framework along with visualization software (VOSviewer) to identify intellectual patterns in publication trend, citations trend, influential journals, influential field of research and new themes map. The analysis highlights a consistent growth in publications from the early 2000s, with output peaking around 2021, followed by diversification into new thematic directions. Contributions are geographically widespread, though the United States accounts for much of the citation influence, particularly through foundational studies by Feldman (2001, 2005) and Sonfield & Lussier (2004). Among journals, Entrepreneurship and Regional Development leads in productivity, whereas Industrial and Corporate Change demonstrates higher citation impact. Bibliographic coupling reveals eight thematic clusters, centering on networks, social capital, proximity, and entrepreneurial capability as drivers of cluster vitality. Emerging topics such as digital entrepreneurship, artisanal industries, and handloom clusters suggest the field’s increasing socio-economic scope. Overall, the findings emphasize clusters as catalysts of innovation, entrepreneurship and regional competitiveness, while offering insights for scholars and policymakers interested in advancing sustainable and entrepreneurship-driven development.

FINANCIAL LITERACY IN MSMEs/SMEs: A SYSTEMATIC LITERATURE REVIEW AND BIBLIOMETRIC ANALYSIS Evidence Synthesis: 2010–2026

Financial literacy is increasingly recognised as a core capability shaping the sustainability, performance, and financing prospects of micro, small, and medium enterprises (MSMEs/SMEs), particularly in developing and emerging economies. Although empirical research on this relationship has expanded rapidly, the evidence remains dispersed across methods, regions, and thematic streams. This study provides an updated synthesis by combining a systematic literature review with bibliometric analysis of 346 peer-reviewed and scholarly publications drawn from Scopus, Web of Science, EBSCO, Google Scholar, and ProQuest for the period January 2010 to July 2026. Using PRISMA 2020 screening procedures and VOSviewer-supported co-citation and keyword co-occurrence mapping, the paper identifies six major intellectual clusters and seven emerging research gaps, traces the intellectual structure of the field, and highlights influential authors, journals, and country-level concentrations. The most recent literature from 2025–2026 points to three important emerging areas: the interaction between artificial intelligence and financial literacy, where AI advisory systems may both support and intensify the value of human financial judgement; climate and ESG finance literacy, which is becoming essential for MSMEs seeking sustainability-linked finance; and the maturation of digital financial literacy research in the context of embedded fintech and decentralised finance. Overall, evidence indicates that financial knowledge, financial attitudes, and financial behaviour together explain between 31% and 58% of the variation in SME performance indicators. The paper proposes an updated conceptual framework incorporating these new dimensions and identifies seven research gaps that frame a forward-looking research agenda up to 2030.

Bibliometric Analysis of the B Corp Movement: Implications for Researchers in Türkiye

This study aims to map the intellectual and conceptual landscape of the B Corp movement within the scientific literature through a quantitative bibliometric analysis. Utilising the Web of Science (WoS) Core Collection database, the research analyses 108 peer-reviewed articles published between 2007 and 2025. Data visualisation and network analysis, including co-authorship and keyword co-occurrence, were performed using the VOSviewer software. The results show that the number of publications has been growing exponentially since 2011, and the majority of the articles are in the business and management field. A total of 282 keywords were evaluated, and “B Corp” (total link strength: 315) and “Corporate Social Responsibility” (total link strength: 92) were identified as central conceptual pillars. The most cited influential work is by Julie Battilana and Alnoor Ebrahim, with 728 citations. Geographic concentration is still strong in the USA and Europe, but research on emerging economies, such as Türkiye, where there are presently 15 certified B Corps, is critically lacking. The results show a conceptual move from general corporate responsibility to specific issues of 'social impact' and 'employee ownership'. The paper concludes with a research agenda for future research that can help bridge the gap between global norms and local institutional contexts, particularly for researchers in Türkiye.
