- A teoria financeira tradicional e a psicologia dos investidores : uma análise empíricaPublication . Fernandes, Carla; Martins, António0 pressuposto da racionalidade, princípio básico da 'teoria financeira tradicional, tem vindo a ser criticado pelos autores da escola designada por "behavioral finance", Estes afirmam que os investidores realizam escolhas incompatíveis com os axiomas da teoria da utilidade esperada, e que nem sempre realizam correctas estimativas acerca da futura evolução das variáveis que tentam prever, Assim, assumindo uma posição crítica, os autores da "behavioral finance" argumentam que os investidores individuais, dependendo de determinados padrões mentais de leitura e interpretação da realidade, são susceptíveis a cometer erros cognitivos na tomada de decisões de investimento, o que os afasta do pressuposto da racionalidade e leva a que as rendibilidades sejam também influenciadas por factores psicológicos, Este artigo pretende apresentar um estudo empírico cujo objectivo foi o de testar se os investidores portugueses apresentavam tendência para cometer erros cognitivos na tomada de decisões de investimento financeiro, Com base no estudo realizado, foi possível concluir que o principal comportamento que domina a totalidade dos indivíduos e a aversão ao risco, Observou-se, também, a preferência pelos dividendos como componente da riqueza, A aversão a perdas constituiu um dos tipos de atitudes evidenciadas, Este comportamento levou os indivíduos a tomar diferentes atitudes face ao risco, manifestando tendência para aceitar mais facilmente o risco perante situações de perdas do que perante situações de ganhos, A sua atitude face ao risco variou também em função das passadas experiências de investimento, Dada a escassez de estudos desta natureza em Portugal, espera-se que este trabalho possa contribuir para um melhor conhecimento da decisão financeira.
- The contribution of digital financial services to financial inclusion in Mozambique: an ARDL model approachPublication . Fernandes, Carla; Borges, Maria Rosa; Caiado, JorgeThis paper analyses the contribution of digital financial services to financial inclusion in Mozambique, based on the Autoregressive Distributed Lag (ARDL) model, for the period from January 2011 to September 2019. We study two models to analyse the contribution of digital financial services to financial inclusion (measured by the number of bank accounts) in Mozambique. The first model uses traditional digital means of payments as independent variables, such as the volume of financial transactions through automated teller machines (ATMs), point-ofsales (POSs), electronic transfers of inter and intrabank funds, direct debit, and domestic and crossborder remittances. The second model considers innovative digital means of payments, such as internet banking, mobile banking and electronic money. We conclude that, excluding domestic remittances and direct debit, which present low levels of penetration in the country, and internet banking transactions, the remaining variables contribute to financial inclusion. Our results confirm the crucial role that digital financial services play in financial inclusion, particularly in improving access to and the use of services by the under-served population.
- The relationship between Financial Inclusion and Monetary Stability in Mozambique: Analysis based on an Error Correction Model (VECM)Publication . Fernandes, Carla; Borges, Maria Rosa; Macome, Esselina; Caiado, JorgeThe present work aims to assess the existence of the relationship between financial inclusion and monetary stability in Mozambique based on the analysis of the vector correction error model (VECM) for the period from 2005 to 2020. The indicators used in the study follow the approach taken by Mbutor and Uba (2013), Lapukent (2015), Lenka and Bairwa (2016) and Hung (2016). In addition to indicators of traditional banking institutions, this article goes further by also incorporating indicators relating to services of electronic money institutions with the objective of capturing the impact of digital financial services on financial inclusion and their role in financial stability. The study presents results consistent with economic theory. The long-term VEC model proved to be statistically significant and confirmed the existence of a long-term relationship between financial inclusion and monetary stability. It also revealed that the deviation of the CPI from its long-term equilibrium is adjusted at a speed of 10.19%. The coefficients of the short-term VEC model were negative for the variables of branches and bank accounts. The coefficients of agents and EMI accounts were not positive, and their shocks are removed after 6 quarters, after which the expected negative sign is observed achieving monetary stability
- Validation of the Comprehensive Feeding Practices Questionnaire (CFPQ) with Portuguese Caregivers of 2-to-8-Year-OldsPublication . Santos, A. F.; Fernandes, M.; Fernandes, Carla; Barros, Luísa; Veríssimo, M.Recent findings have demonstrated an increase in the prevalence of childhood obesity and overweight in Portugal, urging the need to study modifiable risk factors such as parental feeding practices. The Comprehensive Feeding Practices Questionnaire (CFPQ) is an important self-report measure assessing a broad range of responsive and non-responsive feeding practices. However, the CFPQ has not yet been validated in Portugal. Therefore, the present study aimed to test the validity of this measure with Portuguese parents of 2-to-8-year-old children. A sample of 409 parents completed a Portuguese-adapted version of the CFPQ and the already validated Child Feeding Questionnaire (CFQ). Confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and psychometric analysis were conducted. CFA demonstrated the original 12-factor structure did not fit the sample. EFA identified an eight-factor structure comprising 29 items: Monitoring, Modeling, Environment, Involvement, Emotion Regulation, Restriction for Weight Control, Restriction for Health, and Pressure. Findings suggest that parental feeding practices are sensitive to parents’ background cultures and children’s developmental period.
