A study of Indonesia’s 2024 pre-election year Publication-Status: Published Abstract: The political future is inherently unpredictable, particularly in the run-up to elections. This article analyses whether such uncertainty matters. In this paper, we raise an interesting issue of the impact of political debate on the stock market of a developing country. Specifically, we investigate whether people’s economic expectations are conditional on their estimations of potential election outcomes. The subject of this study is the relationship between political events, including the 2024 presidential debate, and Indonesia’s financial markets. The authors analyse stock price movements of the 30 most actively traded issuers, as ranked by the Indonesia Stock Exchange, acknowledging that not all issuers trade daily in this emerging market. Using the Wilcoxon rank-sum test, we assess whether significant differences in investor responses exist before and after the debate periods (debates 1 to 5). According to the findings, investors believe that this event has no impact on their economic decisions, because candidate electability is dominated by incumbent candidates, so it is assumed that there will be no significant changes in financial policy. Therefore, investors appear relatively indifferent to the election dynamics during this period. Overall, the results show that Indonesian people anticipate election outcomes.

The growing complexity of the financial environment, marked by market globalisation, digital transformation and accessibility of sophisticated financial products, creates unprecedented challenges for individual financial decision-making. This situation is further complicated by generational changes and challenges such as underperforming pension systems, making research on economic and financial socialisation particularly relevant and timely. The aim of this article is to review research on economic and financial socialisation, enabling a comprehensive mapping of existing studies and the identification of key topics and underexplored areas that may guide future studies. Conclusions are drawn from a quantified bibliometric analysis of articles from the Scopus database, supplemented by an in-depth content analysis of purposefully selected scientific works. The analysis was conducted using the R environment, specifically the Bibliometrix package and the Biblioshiny functionality. The findings map the status and developments of the research existing in the field, indicating also a need for further research into the impact of economic and financial socialisation on a broad spectrum of financial decision-making in adulthood.

This research proposes an ensemble method based on majority voting (Hard Voting Classifier) of deep learning models to detect fraud transaction. Artificial Neural Network (ANN), Convolution Neural Network (CNN), Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU) have been used as deep learning models. First, the most significant features that affect the type of transaction (fraud or not fraud) have been selected. After that, the ML-DL models were applied. The performance of the proposed approach is tested using a confusion matrix, recall, precision, F-measure and accuracy. The proposed method is tested using accurate data that consists of 540,099 transactions recorded in Kaggle repository dataset of two days based on European card holder for September, 2023. The result shows that the Random Forest (RF) model detected anomalies with 99.99% accuracy, F1-score with 1.00, and excellent recall with 99.99%. As a result, the machine learning model based on RF approach shows promise as a real-time anomaly detection method with high performance and low computational cost.

Categories similar to ES are studied in particular by economics, praxeology (forms of efficiency) and management sciences. These sciences attribute the long-term success or failure of AS to various sources, but not directly/mainly to ES. Profit/loss, as forms of positive or negative ES respectively, can be a source of success/failure of AS. These, in turn, have their own sources and conditions.So far, it has been assumed that profit need not be the guiding principle for the management of any (all) AS. None of the scientific theoretical concepts make claims that recognise and solve the broader problem of the sources of longevity of any (all) AS. I try to offer a solution using a praxeological and systemic approach, prognostic-diagnostic methodology and hypothetical-deductive reasoning.I argue that the most important source of longevity is ES. The efficiency of the AS must always be greater than that required to repeat the cycle of action at the initial level and to make the necessary changes. Over the long term, a surplus must be achieved by any (all) AS. (...)

Crises include economic recessions, financial shocks, pandemics and global disruptions. A bibliometric analysis of Scopus-indexed literature from 1998 to 2024 was conducted to address influential authors, key journals, themes and countries. Excel was used to perform statistical analysis, while VOSviewer was used to visualise the authors’ keywords in a network. The study focuses on the fields of business, economics and finance, emphasising their critical role in steering turbulent markets. The findings indicate a significant increase in research related to the CSF of enterprise competitiveness during major disruptive events, particularly during economic and financial crises. Countries such as the UK, China, Malaysia and India rank among the top publisher countries. Major themes focus on business resilience, supply chain continuity and organisational agility as core pillars for enterprises to maintain their competitiveness. Although this article relied on the Scopus database, its findings remain valuable, providing a solid foundation for future research. This study serves as a guide for experts, managers and policymakers on evidence-based strategies – such as risk management, dynamic capabilities and leadership agility (...).

Through a case study of Al-Amal Microfinance Bank in Yemen, the research highlights the bank’s effectiveness in expanding access to financial services via tailored solutions and strategic outreach. By deploying a network of financial and non-financial agents in remote areas, alongside digital banking platforms, Al-Amal Bank successfully mitigates barriers such as distance, cost and accessibility. The integration of electronic services further enhances financial access, contributing to more inclusive development across the country.

The article examines the modernisation of the Roucas Blanc facilities, Marseille, for 2024 Summer Olympics nautical events. It discusses tourism and image-related benefits. The study used a mixed method. Firstly, secondary materials, including Marseille’s official project documents and development strategies were collected and analysed. Secondly, field studies with photographic documentation of the modernised Roucas Blanc Marina focused on functionality and architectural solutions. Thirdly, a survey among coaches of the Polish sailing team preparing for the Olympics was conducted. Despite the shortage of respondents, the survey provided expert opinions on the port facilities. The documents confirmed that nautical infrastructure is a cornerstone of Marseille’s promotional strategy. The photographs revealed architecturally and functionally coherent development and facilities well integrated into the surroundings. The coaches appreciated the facility’s modernity and indicated their intention for future training camps there. The study confirmed that the Roucas Blanc Marina modernisation strengthens Marseille’s image and can promote the long-term sports tourism development. The limited survey scope and the scarcity of data following the Games indicates the need for further long-term analyses of the impact these investments have exerted on the city.

Global applicability to countries with similar types of retirement plans is emphasized. A full factorial simulation assessed 54 unique combinations of IRA type, investment mix, and tax rates during working and retirement years. Results indicate that investment type plays a more critical role than IRA type in determining outcomes. Portfolios with significant exposure to the S&P 500 consistently achieved higher ending balances and longer-lasting funds compared to portfolios relying on lower-yield investments. Traditional IRAs, leveraging frontend tax advantages, performed best when tax savings were reinvested, though Roth IRAs provided tax-free withdrawals, maximizing backend benefits.Key findings include the importance of starting early, maintaining significant equity exposure throughout life for higher returns, and understanding that IRA type often has a marginal impact relative to investment strategy. The study highlights that the most effective strategy is situational, influenced by factors such as tax rates and market conditions. These insights, while grounded in U.S. data, offer guidance for retirement planning systems globally. Policymakers and individuals are encouraged to prioritize early, consistent, and aggressive investment strategies to optimize retirement outcomes.
