Item type: Item , Competencia geopolítica, transición energética y oportunidades de desarrollo para economías periféricas: el caso del litio en economías de América del Sur(Universidad de Huelva, 2026) Kulfas, MatíasEste trabajo analiza el papel estratégico del litio en la transición energética y la competencia geopolítica entre China y Estados Unidos. Se examina el rol del Triángulo del Litio (Argentina, Bolivia y Chile), sus modelos de gobernanza y las oportunidades de industrialización local. Se plantea que, para superar la dependencia exportadora primaria, es clave atraer inversiones automotrices que integren la cadena de valor del litio con la electromovilidad. Una estrategia regional coordinada —particularmente entre Argentina, Brasil y Chile— permitiría aprovechar sinergias industriales y mejorar la posición negociadora de América del Sur en un contexto global crecientemente competitivo. ---------------------------------------------------------------------------------------------------------Item type: Item , Finanzas sostenibles, banca ética y cooperativas de crédito: una revisión de la investigación mundial(Universidad de Huelva, 2026) Herrador Lindes, InmaculadaLa sostenibilidad exige financiación, tal y como recoge la Agenda de Acción de Addis Abeba. A partir de la exploración de la investigación desarrollada en las últimas décadas, utilizando el software SciMAT, este trabajo analiza el papel de la banca ética y las cooperativas de crédito como impulsoras de proyectos sostenibles. Los resultados muestran que existe un interés creciente por el tema. Asimismo, el análisis de palabras clave pone de manifiesto el protagonismo de los trabajos centrados en aspectos económicos y sociales, frente a un menor peso de los que se refieren a cuestiones vinculadas al cambio climático y la conservación del medio ambiente. ---------------------------------------------------------------------------------------------------------Item type: Item , External debt duplication in Latin America and the World: Evidence from VCOA-adjusted measures(Universidad de Huelva, 2026) Carrera, Andrea; Mazoni, AlyssonThis paper investigates the phenomenon of external debt growth in Latin America, drawing on valuation-adjusted measures to reassess debt dynamics during current account deficit episodes between 1970 and 2023. By comparing conventional statistics with adjusted indicators that incorporate valuation changes and other adjustments (VCOA), the study uncovers systematic asymmetries or “mirror ratios” in which debt accumulation alternates between under- and over-adjustment relative to the theoretical benchmark. At the aggregate level, however, the evidence reveals a persistent upward bias, consistent with a structural tendency towards over-indebtedness. The results for Latin America are also confirmed when taking into account a number of countries representative of the world as a whole. This indicates that the patterns observed in the region are not an isolated phenomenon, but rather part of a broader and consistent international trend worthy of further investigation, with implications for external vulnerability assessments and global financial governance. ---------------------------------------------------------------------------------------------------------Item type: Item , The Influence of China's Outward FDI in RCEO Countries on Bilateral Trade: The Mediating Role of the Digital Economy(Universidad de Huelva, 2026) Wang, Siwen; Latiff, Abdul Rais AbdulThis study employs an extended gravity model to assess the impact of China’s direct investment in the Regional Comprehensive Economic Partnership (RCEP) member countries on trade. After measuring the digital economy levels of these countries using principal component analysis, a mediation effect model is applied to examine whether the digital economy serves as an intermediary variable. The results indicate that China’s direct investment in RCEP countries has a positive impact on China’s exports, imports and total trade value with these countries. Moreover, the digital economy plays a positive mediating role in facilitating these trade-enhancing effects. ---------------------------------------------------------------------------------------------------------Item type: Item , Technological Power and Persistent Dependency in Latin America: China, the United States, and the Regional Patent Network (2013–2023)(Universidad de Huelva, 2026) Vázquez Rojo, JuanChina’s expanding technological footprint in Latin America and the Caribbean (LAC) is challenging traditional patterns of dependency dominated by the United States. This article applies Social Network Analysis (SNA) to examine technological power dynamics through foreign patent registrations between 2013 and 2023. By analyzing centrality and concentration, the study assesses the persistence of asymmetries in the region’s technological network. The findings show that, despite China’s growing influence, the core–periphery structure remains intact and technological dependency continues to revolve around historical powers. ---------------------------------------------------------------------------------------------------------Item type: Item , Impact of economic policy uncertainty on stock exchanges: Evidence from a panel analysis for the period 2003-2020(Universidad de Huelva, 2026) Sánchez Gabarre, Mary Elena; Castellanos García, PabloThis study analyses how uncertainty affects global stock markets between 2003 and 2020, specifically through a threefold perspective: economic policy uncertainty, geopolitical risks and financial market volatility. In doing so, using a panel data approach, we assess whether such uncertainty has a homogeneous impact across different economies. In addition, both the levels and variability of uncertainty are considered and a cluster analysis and ANOVA are performed to identify patterns across a score of countries at the international level. The results of the random effects model show that economic policy uncertainty, geopolitical risk, interest rates and inflation have negative effects on stock markets, while economic growth and exchange rates have positive effects. ---------------------------------------------------------------------------------------------------------Item type: Item , Food Loss and Waste Across the Supply Chain: A Comparative Analysis of Developed and Developing Countries(Universidad de Huelva, 2026) Clemente González, José Ignacio; Montero Simo, María José; Torres Jiménez, Mercedes; Muñoz Ocaña, YolandaFood loss and waste (FLW) is a major global challenge with significant social, environmental, and economic impacts. The Food and Agriculture Organization (FAO) estimates that one-third of food produced for human consumption is lost or wasted annually, amounting to 1.3 billion tonnes. This study analyzes FLW variations across supply chain stages in developed and developing countries using the FAO 2022 database (21,736 observations, 149 countries). Inferential statistical analysis (Kruskal-Wallis tests) evaluates differences in FLW by stage and country development level. Results show higher FLW in developed countries (39.67%) than in developing ones (21.87%). Developed nations experience more waste in Distribution (10.0%) and Consumption (17.0%), while developing nations face losses in Agricultural Production (2.5%) and Postharvest Handling. Findings highlight the need for tailored interventions: infrastructure and technology enhancements in developing nations, and policy-driven consumer behavior changes in developed ones. Solutions include improved supply chain transparency, AI-driven demand forecasting, food donation programs, and consumer awareness campaigns. This research advances FLW understanding and informs policies for their elimination. Future studies should refine quantification methods, assess policy impacts, and explore technological solutions to mitigate FLW’s environmental and economic effects. ---------------------------------------------------------------------------------------------------------
