- 2024 U.S. presidential elections: An event study for U.S. and non-U.S. fossil fuel and renewable listed firmsPublication . Martins, António Miguel; Albuquerque, Bruno; Sardinha, Luís; Moutinho, NunoThis study examines the short-term market effect of Donald Trump' victory in the 2024 US presidential election on largest US and non-US listed worldwide fuel fossil and renewable firms. Employing an event study methodology, we observe a negative and statistically significant stock price reaction for worldwide renewable listed firms. An analysis by economic zones reveals the existence of negative abnormal returns for renewable energy firms in the US, Europe, India and in the rest of the world. In the case of China, abnormal returns are not statistically significant. With respect to worldwide fossil fuel listed firms, abnormal returns are generally not statistically significant. However, regarding US firms, we observe positive and statistically significant abnormal returns. These abnormal returns are explained by the change of US energy policy (pro-oil and gas policy) and the expected cut in subsidies and lower profitability of investments in green energies. Finally, our study provide insight into which firm-specific characteristics emerge as value drives around US presidential elections. The results show that despite the change in environmental policy in the US, favourable to fossil energy, the stock markets reward firms with high environmental ratings. Overall, our results indicate that 2024 US presidential election, for implying a change in US energy policy, has relevant policy implications for energy listed firms.

- A literacia financeira dos estudantes no ipb oriundos dos PALOPPublication . Sanuó, Beto; Monte, Ana PaulaA crescente complexidade dos mercados financeiros e a necessidade de decisões económicas responsáveis tornam a literacia financeira uma competência crítica no ensino superior. Este estudo avaliou o nível de literacia financeira de estudantes oriundos dos Países Africanos de Língua Oficial Portuguesa (PALOP) matriculados no Instituto Politécnico de Bragança (IPB) e identificou fatores associados aos seus conhecimentos, atitudes e comportamentos financeiros. Recorreu-se a um desenho quantitativo, com inquérito aplicado a 161 estudantes e análise no Jamovi, utilizando estatística descritiva e inferencial (testes t de Welch, ANOVA/Kruskal–Wallis, Qui-Quadrado e correlações de Pearson/Spearman). Os resultados indicam literacia global moderada, com melhor desempenho em planeamento financeiro e fragilidades em compreensão financeira. No índice global, não se observaram diferenças significativas por género, área científica ou ano de frequência. Ao nível das dimensões, verificaram-se diferenças por ano e associações positivas com a idade em variáveis comportamentais: Planeamento Financeiro (r≈0,48; p<0,001) e Fontes de Informação (r≈0,22; p<0,001). Estes padrões sugerem que maturidade e experiência se traduzem sobretudo em melhores práticas de organização e procura de informação, não implicando, porém, ganhos uniformes no índice global quando persistem lacunas conceptuais. Conclui-se que reforçar a educação financeira transversal, com módulos curriculares breves, oficinas práticas de orçamento/poupança e literacia informacional, poderá melhorar competências aplicadas e consolidar conhecimentos, potenciando o sucesso académico e a integração social dos estudantes internacionais. Recomenda-se a implementação e monitorização de programas institucionais de literacia financeira no ensino superior português.

- Ação social no Ensino Superior face aos objetivos de desenvolvimento sustentável da ONUPublication . Praça, Lídia GalvãoO ano de 2015 fica associado ao lançamento da Agenda 2030 para o Desenvolvimento Sustentável, adotada por todos os países integrantes das Nações Unidas (ONU), cujo intuito foi definir prioridades e aspirações para o desenvolvimento sustentável global. Nela se incluem 17 Objetivos de Desenvolvimento Sustentável (ODS), cada um com várias metas para a respetiva concretização. De acordo com o Conselho Empresarial para o Desenvolvimento Sustentável (BCSD Portugal, 2025), os ODS constituem uma oportunidade única e necessária para apoiar um crescimento sustentável, regenerativo e inclusivo, sem o que será impossível fazer face à emergência climática, à perda galopante de biodiversidade e às desigualdades e assimetrias sociais. Refere que Portugal teve um papel ativo na elaboração e na consequente implementação da Agenda 2030 e que em 2017, reforçou o seu compromisso, ao ser um dos países que apresentou, de forma voluntária, um “Relatório nacional sobre a implementação da Agenda 2030 para o desenvolvimento sustentável”, no qual se podia comprovar as ações levadas a cabo a nível nacional relativamente a cada um dos ODS. Segundo este relatório, Portugal materializa nos ODS 4, 5, 9, 10, 13 e 14 as suas prioridades estratégicas na implementação da Agenda 2030 para o Desenvolvimento Sustentável. A ONU monitoriza o progresso dos países ao nível dos ODS através do SDG Index & Monitoring. Entre 2015 e 2019, o progresso mundial na concretização dos 17 ODS foi de 0,5% ao ano, um ritmo considerado insuficiente para serem atingidos até 2030. Adicionalmente, em 2020 e 2021 não se registaram progressos, sobretudo devido à performance negativa dos países em desenvolvimento. Saliente-se que em 2022, o relatório da ONU sobre desenvolvimento sustentável, conduzido por cientistas independentes, destacou Portugal como um dos países mais sustentáveis do mundo (BCSD Portugal, 2025). Passada uma década sobre a aprovação desta ambiciosa agenda, é tempo de fazer uma análise sobre a evolução desses objetivos e consequentemente refletir sobre o nível de (in)cumprimento. É neste contexto que nos propomos apresentar este trabalho, restringindo a análise ao caso de Portugal e à implementação de dois dos 17 objetivos: o ODS 4 e o ODS 5. Da pesquisa bibliográfica efetuada, foram encontrados vários trabalhos sobre esta temática, mas nenhum deles, conjugando estes dois ODS e horizonte temporal.
