Abstract

There have been many criticisms of modern portfolio theory. The framework of modern portfolio theory is static, modern portfolio theory assumes that assets are normally distributed. But in times of financial crisis or pandemic, asset class correlations increase, and assets lose value more than normal distributions would expect. This study empirically whether it is possible to apply modern portfolio theory using additional criteria. The criteria proposed are based on financial ratio analysis, using debt ratios expressed as debt to equity and profitability ratios expressed as return on assets. Based on the analysis, modern portfolio theory can be applied using these additional criteria. The analysis shows that portfolios that have a low debt to equity and portfolios with low asset returns or have good performance. But when viewed from the risk, portfolios with a debt to equity ratio of less than one are more diversified so that they are low risk, as well as portfolios with a return on assets of more than 0.1 have a low risk. Risk-averse investors who are trying to experience losses in times of financial turmoil or the current Covid-19 pandemic can add criteria that do not refer to the normal distribution. This research brings new alternative techniques to investors and adds a new dimension to the ongoing relevance of modern portfolio theory.

Abstract

Especially when it comes to Micro, Small, and Medium-Sized Enterprises (MSMEs) in Indonesia, financial literacy is crucial in guiding investment decisions. In this quantitative study, the relationship between MSME owners' and managers' investment decisions and the elements of financial literacy—financial knowledge, financial competence, and financial behavior—is examined. Data from the survey were analysed using Structural Equation Modelling with Partial Least Squares (SEM-PLS), and 164 respondents made up the sample. The results demonstrate that investing decisions are influenced by a combination of financial behaviour, financial competence, and financial awareness. Specifically, more informed, strategic, and cautious investing choices are linked to better financial literacy levels. The findings of this study demonstrate how crucial it is to raise financial literacy among Indonesia's MSMEs in order to foster competitiveness and economic growth. For practitioners, policymakers, and business owners who wish to equip MSMEs with the financial literacy and decision-making abilities necessary for wise investment choices, this study offers insightful information

Abstract

The development of information and communication technology has resulted in an unprecedented explosion of data, known as Big Data. This phenomenon has influenced various aspects of the economy, including Market Microstructure, which is a highly detailed study of the behavior and structure of financial markets. Big Data has enabled market researchers and practitioners to improve the efficiency of Market Microstructure in an unprecedented way. This study utilizes the literature review method to investigate the role of Big Data in improving Market Microstructure efficiency. The results of the literature review show that Big Data has the potential to change the Market Microstructure landscape in several key ways. First, Big Data enables more sophisticated and real-time market monitoring, allowing for faster and more accurate decision-making. Second, Big Data can be used to analyze larger and more complex market data, which can reveal patterns and trends that were previously difficult to discover. Thirdly, Big Data enables the development of better predictive models to forecast price movements and market liquidity. In addition, the literature review also revealed challenges and issues associated with the use of Big Data in Market Microstructure, including data privacy and security concerns, as well as difficulties in managing and analyzing massive and diverse data. Therefore, the use of Big Data in Market Microstructure requires careful attention to ethical and regulatory aspects. In order to improve the efficiency of the Market Microstructure, Big Data has opened up exciting new opportunities, but also presents challenges that need to be addressed. With the right approach, Big Data can provide valuable insights and improve our understanding of financial market behavior, which in turn can improve market efficiency and benefit stakeholders in the financial markets.

The company's financial performance is measured using financial ratios, namely: Return On Assets (ROA), Current Ratio (CR) and Debt To Asset Ratio (DAR). The analytical method used in this research is the T-test difference analysis and the Wilcoxon signed rank test. The research results show that companies that carry out mergers and acquisitions in 2020-2022 with an average period of 1 year before and 1 year after the merger and acquisition show that there is no difference in profitability as indicated by Return On Assets (ROA), liquidity as indicated by Current Ratio (CR), solvency shown by Debt To Asset Ratio (DAR), before and after mergers and acquisitions. This research was conducted incompanies that carry out mergers and acquisitions in 2020-2022 and are listed on the Indonesian Stock Exchange. This study provides an in-depth understanding of how mergers and acquisitions affect the financial performance of companies in the Indonesian capital market. Therefore, stakeholders such as investors, company managers, regulators and academics can gain a better understanding of the impact of merger and acquisition activities on the Indonesian economy. There has been no research regarding the effect of mergers and acquisitions on financial performance in the 2020-2022 period in Indonesia. This knowledge gap is the reason for conducting this research.

Abstract

This study examines the revenue growth performance of Ghana's Metropolitan, Municipal, and District Assemblies (MMDAs) and explores the moderating influence of population density on the relationship between financial autonomy and revenue growth. This study analyzes the impact of institutional capability and spatial context on subnational fiscal performance in the context of Ghana's decentralization, based on fiscal federalism and institutional theory. Auditor-General's Reports and the Ghana Statistical Service provided data on 261 MMDAs from 2018 to 2023. Stata 18 and R 4.3 were used for fixed-effects estimation, the system generalized method of moments (GMM), robustness testing, and moderation analysis using Hayes' PROCESS Model 1. The results indicate that financial autonomy substantially improved subnational revenue growth (β = 0.0036, p < 0.001). Population density did not significantly reduce this association (β = -0.0031, p = 0.108). Further analysis indicates that the fiscal benefits of autonomy are more pronounced in low-density assemblies, suggesting that institutional and administrative efficiencies play a more critical role in fiscal performance than population size. The findings indicate that decentralization reforms should prioritize improving governance quality, institutional discipline, and fiscal accountability, rather than demographic or spatial considerations. This study represents the first application of moderated panel models to 261 Ghanaian MMDAs, demonstrating that institutional strength, rather than population density, serves as the principal determinant of fiscal benefits from autonomy in developing countries. This finding contributes to the discussion on fiscal federalism and institutional theories.
