Application of predictive artificial intelligence (AI) models to estimate the success of crowdfunding
This research presents a novel approach utilizing a self-enhanced chimp optimization algorithm (COA) for feature selection in crowdfunding success prediction models, which offers significant improvements over existing methods. By focusing on reducing feature redundancy and improving prediction accuracy, this study introduces an innovative technique that enhances the efficiency of machine learning models used in crowdfunding. The results from this…
Corruption as a barrier to sustainability
This study investigates how corruption impacts sustainability in African countries. Using public databases, the research draws on the African Development Bank’s corruption indicators and the World Bank’s financial inclusion metrics. The findings reveal that as financial inclusion increases, particularly through the use of digital financial services, perceptions of corruption decrease. However, economic growth paradoxically correlates with an incr…
Trends of standard of living preferences of economics university students as a result of the economic crisis
One of today’s central subject ranges is the theme of personal financial decisions. Standard of living preferences are also closely related to these. The generation that will soon enter the labor market still has these questions in front of them. This is the reason why we focused on university students in our study. We asked Hungarian, Austrian, and Slovak economics students in our questionnaire research. We conducted the study in 2 successive ye…
Examining the effectiveness of fundamental analysis in a long-term stock portfolio
Over the past decade, a number of modern and sophisticated methods have been developed to optimize the composition of equity portfolios. Most of these methods are based on complex mathematical or financial modelling. Less emphasis has been placed on companies’ internal data, while in recent years external data have become increasingly important. However, for long-term investments, the dominance of external data is not necessarily an efficient way…
