- Factors influencing the quality of financial information: a systematic literature reviewPublication . Landu, Masidivinga; Mota, Jorge H.; Moreira, Antonio; Bandeira, Ana MariaPurpose: This research seeks to identify the key factors influencing the quality of financial information within the context of globalisation and complex commercial transactions. Motivation: In today’s globalised environment, trust in financial information is crucial for maintaining market stability and efficiency. Understanding these influencing factors is paramount for sound decision-making by firm managers. Design/Methodology/Approach: A Systematic Literature Review methodology is employed. The investigation examines 50 articles from the SCOPUS and Web of Science databases to identify the key determinants affecting financial information quality. Main findings: The investigation identifies critical factors at firm, country and international levels. Firm-level factors include corporate governance practices, incentives for transparent disclosure and bank monitoring. Country-level influences stem from regulatory frameworks and firm-agent dynamics. Finally, international factors involve competition within capital markets and the degree of a firm’s internationalisation. Practical implications: The research provides key recommendations for both firm managers and regulatory bodies. Managers are advised to adopt transparent policies, implement rigorous audit processes and foster a culture of integrity and accuracy. Additionally, strengthening regulatory bodies and supervisory entities is crucial for effectively monitoring financial practices and penalising misconduct. Novelty/Contribution: This research represents a pioneering effort to systematically synthesise factors affecting financial information quality. It provides a comprehensive framework for academics and practitioners, promoting sustainable economic growth and informed decision-making.
- Measuring the simultaneous quantity game in OMEL spot electricity marketPublication . Moutinho, Victor; Moreira, Antonio; Mota, Jorge H.In the electricity spot market the various competitive levels, as well as their subsequent changes in the market equilibrium, are justified by the simultaneous quantity game between electricity generators. It is expected that the dominant market players employ differentiated strategic behaviours, thus, permitting the quantification of such differentiated effects on the use of market power. The various competitive levels, as well as their subsequent changes in the market equilibrium, are justified by the simultaneous quantity game. The results show that the quantities purchased in the spot market for sale in open market influence prices, i.e., when there is an imbalance in the estimated long-term relationship, prices themselves move in order to recover the state of equilibrium, which reveals that, in the long-term, the OMEL Price is weakly exogenous to the cointegration vector, whereas quantities purchased for sale in open market move towards the reestablishment of the long-term equilibrium.
