Special Issue Information

Dear Colleagues,

Financial markets around the world are facing unprecedented challenges, both regarding the sudden changes in the fundamental values of traditional assets and across competing new assets which possess no theoretical fundamental financial value. There are growing concerns; therefore, on the sustainability of finance amidst chaotic patterns of movements, we aim to accurately predict financial returns and inclusively distribute net returns. This Special Issue is seeking contributions from researchers which can advance our understanding on the challenges and strategies to deal with them. Both theoretical and empirical contributions are welcome. The following broad areas can be considered:

  • Dynamic interactions between traditional assets and cryptos, studying, for instance, the risk appetite nature of investments and possible diversification and hedging;
  • Predictions of cryptos and traditional assets by considering joint co-movement;
  • Policy support and sustainability;
  • Machine learning and ESG investment;
  • Blockchain and productivity.

Insurance companies play a pivotal role in the financial systems of developing countries, wielding substantial influence on systemic financial stability. Thus, understanding their efficiency, performance, and sustainability is paramount for policymakers and stakeholders alike. The aim of this paper is to evaluate the relative efficiency of insurance companies within the North Macedonian market spanning the years 2018 to 2022. Employing the input-oriented BCC DEA model, the study integrates capital and labour as inputs, while assessing risk-pooling/bearing services and intermediate function as outputs. Our findings underscore the fluctuating efficiency levels within North Macedonia’s insurance sector. Notably, the sector exhibited its peak efficiency in 2018 at 83.62%, dipping to its lowest point of 73.81% in 2020. Moreover, discerning between life and non-life insurers, we observe an average relative efficiency of 0.8067 for non-life insurers, contrasted with a higher average efficiency score of 0.9011 for life insurance companies over the examined period. This study contributes significantly on multiple fronts. Firstly, it pioneers empirical investigation of the efficiency on the North Macedonian insurance market, encompassing pre- and post-COVID efficiency metrics. This fills a notable gap in the literature, particularly within the context of emerging European markets. Secondly, our comprehensive approach facilitates a holistic evaluation of the insurance sector’s performance across a five-year span, offering insights into its overarching dynamics and efficacy. Thirdly, the implications of our findings extend to policymakers, regulators, and insurance company management, aiding in informed decision-making and strategic planning. Full article

This study investigates the impact of green equity indices on global market dynamics using a time-varying parameter vector autoregression (TVP-VAR) model. We uncover a significant shift in the role of the global market, transitioning from a shock transmitter to a shock receiver, as the influence of green finance grows. By directly comparing green equity indices with their corresponding global parent indices, we adopt a global perspective that transcends the limitations of studies focusing on specific regions, such as the USA, China, or Europe. This novel approach minimizes the potential biases in the transmission channels within regional markets, enabling a more comprehensive understanding of the relationship between green finance and global market dynamics. Moreover, by focusing on equity indices we ensure a consistent comparison of financial instruments, avoiding the complexities that arise when comparing different asset classes such as green bonds and conventional equities. For global investors, our results highlight the importance of dynamic and flexible hedging strategies that adapt to the distinct characteristics of green assets and their growing influence on the global market. Risk managers should incorporate these time-varying spillover effects into their models to better assess and mitigate potential risks. Policymakers should consider the growing influence of green finance on the broader market when formulating regulations and incentives to support sustainable investing, as our findings underscore the increasing importance of this sector in shaping market dynamics.

The financial markets, shaped by dynamic forces, including macroeconomic trends and technological advancements, are influenced by a multitude of factors impacting the S&P 500 stock index, a pivotal indicator in the US equity markets. This paper highlights the significance of understanding the exogenous variables affecting the index’s profitability for academics, portfolio managers, and investment professionals. Amid the global ramifications of the S&P 500, particularly in combating the eroding purchasing power caused by inflation, investing in stock indexes emerges as a means to safeguard wealth. The study employs various statistical techniques, emphasizing a methodical approach to uncover influential variables, and using static regression and autoregressive models for immediate and time-lagged effects. In conclusion, the findings have broad practical implications beyond investment strategy, extending to portfolio construction and risk management. Acknowledging inherent uncertainties in financial market forecasts, future research endeavors should target long-term trends, specific influences, and the impact of exchange rate fluctuations on index evolution. Collaboration across regulatory bodies, academia, and the financial industry is underscored, holding the potential for effective risk monitoring and bolstering overall economic and financial market stability. This research serves as a foundational step towards enhancing market understanding and facilitating more efficient investment decision-making approaches. Full article

The process of deepening the economic integration of European economies reached its peak with the formation of a supranational entity for conducting monetary policy. However, the high degree of financial integration of the market also implied the vulnerability of the economic union in terms of prompt reaction to external shocks with divergent effects. Oil price fluctuations are of essential importance for macroeconomic performance, which is particularly reflected in countries more dependent on the import of this raw material. This research aims to apostrophize the asymmetric effects of oil price fluctuations on the stock market indices on a sample of higher (Germany, Italy, France) vs. lower (Croatia, Bulgaria, Ireland) oil importers. The empirical findings are determined based on impulse response functions derived from the VAR model as well as the Granger causality test of the relationship between stock market indices and oil price fluctuations. In order to identify the isolated impact of oil price movements on stock market indices of selected European economies, the VAR (Vector AutoRegression) model is evaluated in the time period 2013M1-2023M1. The results of the research indicate an asymmetric mechanism of the impact of oil shocks on the financial markets of EU member states. Full article
