The development of investment processes is significant for a country’s economy, economic development, and the expansion of market opportunities. The successful functioning of the national economy in the global economic space requires its integration into the international finance system. The impact of foreign direct investment on the economy of host countries remains relevant. The purpose of this study is to investigate the impact of foreign direct investments on the Gross Domestic Product of Turkey for the years 1990–2021. The data set includes foreign direct investments, exchange rate levels, and the Gross Domestic Product of Turkey and was used in logarithmic form in the empirical assessments. The results show a positive and statistically significant relationship between foreign direct investments and Gross Domestic Product. A long-term integrative relationship exists between the independent variables (foreign direct investments and exchange rate) and the dependent variable (Gross Domestic Product). Consequently, this implies that a 1% increase in foreign direct investment results in a 0.35% increase in Gross Domestic Product, holding other factors constant.

Public debt plays a crucial role in the economic development of many countries, the effective management and servicing of the external public debt have become a priority in the financial and economic policy of the state, ensuring the stability of its development. The article aims to develop Ukraine’s external public debt management system during the wartime. As a result of the analysis, the key negative consequences of the impact of external debt growth on Ukraine`s economic security were determined, i.e. economic growth slowdown, increased dependence on creditors, increased costs of the public debt servicing, significant reduction in domestic consumption, etc. The developed external public debt management system in the framework of state economic and financial security includes relevant subsystems, principles, functions, objects and subjects, methods. It was substantiated that the appropriate external public debt management system during wartime in Ukraine requires the following additional subsystems: subsystem of crisis planning and response, subsystem of external debt settlement and subsystem for ensuring international cooperation.

Fintech has revolutionized the financial services sector, fundamentally transforming how individuals and businesses manage their finances. However, effective and responsible utilization of these innovative services may require a certain degree of financial competence. To explore this possibility, this study investigates the nexus between financial literacy and fintech usage in the Indian context, considering two distinct measures of financial literacy. Primary data were collected conveniently from 391 respondents through a cross-sectional survey. Probit regression was applied to analyze the relationship between the two dimensions of financial literacy and the adoption of fintech services across three segments: mobile banking, mobile payments, and digital lending. The findings reveal a positive relationship between individuals’ subjectively perceived financial literacy and their propensity to use all three fintech services. Conversely, objectively measured financial literacy demonstrates a positive association only with the likelihood of using mobile banking. The study also identifies demographic characteristics as contributing factors to variations in fintech adoption. The study’s findings hold value for policymakers and fintech service providers, as they underscore the importance of enhancing individuals’ subjective perceptions of their financial abilities to promote wider adoption of fintech services.

Understanding the macroeconomic factors is essential for all firms operating in the economy. Investment decisions, financing decisions, and risk management of firms are influenced by the existing macroeconomic factors, thereby impacting their performance. This paper examines the effect of macroeconomic factors on the performance of Indian manufacturing firms. Two-step generalized method of moments model is applied in this investigation to analyze the effect of firm performance from the financial year 2004-05 to 2021-22. Firm performance is proxied by two accounting-based measures and a market-based measure, namely, return on assets, return on equity, and Tobin’s Q, respectively, while the macro-economic factor is proxied by annual gross domestic product growth rate. The empirical findings show that firm performance has a positive relationship with macroeconomic factors. In addition, the findings reveal that firm size, firm age, leverage, sales growth, and operating profit impact firm performance. The study further extends to examine the moderating effect of financing constraints (measured by firm size and age) on macroeconomic factors and firm performance. The results show that the effect is more pronounced on small and young firms as compared to large and mature firms. The study also evaluates the impact of macroeconomic factors on firm performance excluding the crisis periods (the financial crisis of 2008 and the COVID-19 pandemic) and finds the impact on the market performance to be insignificant during non-crisis periods. This study recommends that lenders, managers, and other stakeholders should take proactive policy measures for any anticipated adverse changes in macroeconomic factors on the performance of Indian firms.

This study analyzes the possible impact of diversity in non-interest income on Nepalese Depository Financial Institutions (DFIs) performance. The study examines variables such as service fees, dividends on equity instruments, and the non-interest revenue ratio to total operational income as endogenous factors. The ROE serves as the key profitability indicator. Additionally, the study explores the impact of control variables on the performance of financial institutions, such as the cost-to-income ratio, the equity-to-total assets ratio, and the ratio of non-performing loans to total loans. Secondary data from fiscal year 2015/16 to 2021/22 are utilized for analysis, employing correlation and regression analyses to assess the relationships between variables. Based on the Hausman Specification test, this study uses a Dynamic Analysis of Panel Data approach, adopting a Random effects regression model. The findings indicate that dividends from equity instruments ( = –0.565*) adversely affect profitability. At the same time, service fees and non-interest revenue as a proportion of overall operating revenue show no significant impact. Control factors like the cost-to-income ratios ( = –0.432**) and the equity-to-total assets ( = –94.101**) adversely affect profitability. The study suggests that income diversification may not be beneficial, urging Nepalese DFIs to prioritize interest income and consider alternative investment opportunities. Reducing the cost-to-income ratios and equity-to-total assets is recommended for enhancing profitability.

Economic policy uncertainty intensified as a result of the global financial crisis. To overcome these obstacles, firms handle issues with financial distress and crash risk more proactively. This paper offers new insights into the relationship between financial distress and crash risk on the Egyptian stock market during the period of 2014–2021 and presents how managers strengthen the bad news hoarding mechanism to their advantage. Data were collected via financial statements and reports obtained from the Thomson Reuters database using 824 annual observations of 103 Egyptian firms via the generalized method of moments and ordinary least squares. Results show a strong positive impact of financial distress on crash risk using OLS and GMM. Results support the role of managerial opportunism to cover up bad news that undermines a firm’s economic fundamentals. The findings support an agency theory of how financial distress affects crash risk. The findings support conducting robust tests for alternative financial distress and crash risk measures.

The relationship between economic growth and the development of financial systems has been analyzed from different perspectives for a long time. This paper addresses the effects of the informal economy on the relationship between financial development and economic growth, using a panel data covering 20 countries during the period 1993–2020. The results show that financial development, as measured by the IMF’s Financial Development Index, is positively associated with economic growth (the coefficient α1 related to financial development fd is positive and statistically significant at 5%). The results also show that large sizes of the informal economy moderate the influence of this association (α1 remains positive and statistically significant at 1%, while the coefficient α2 related to the interaction between financial development and informal economy, fd and ie, is negative and statistically significant at 1%). In effect, financial development has the greatest impact on economic growth whenever there is control over the informal economy’s size. Inversely, a favorable ground for the informal economy limits the positive association between financial development and economic growth. However, the results show the absence of a causality relationship between financial development and economic growth (W-bar = 1.0015 and Z-bar = 0.0048; p-value = 0.9980). The informal economy plays no role in making this type of link significant (W-bar = 0.9761 and Z-bar = -0.0756; p-value = 0.9520).

Financial statements are often number intensive, and determining the importance and relevance of these numbers from the perspective of investors and equity holders is paramount. However, empirical studies concerning the correlation between several accounting and economic-based indicators with shareholder returns have yielded contradictory results. Additionally, considering the relatively limited studies on economic-based indicators such as refined economic value-added and economic value-added momentum, this study evaluated the predictive power of refined economic value added, economic value-added momentum, and economic value added (economic-based indicators), along with traditional accounting-based indicators such as return on equity and earnings per share on the shareholders' returns. The study employed fixed-effect instrumental variable regression and panel quantile regression techniques to examine 49 non-financial companies listed on the Johannesburg Stock Exchange from 2007 to 2021. Overall, the results showed that economic value added is a significant negative predictor of shareholder returns, while refined economic value-added is a positive determinant. In addition, the refined economic value-added coefficient remains positive, with the impact increasing across the conditional quantiles. This study concludes that refined economic value-added provides a superior and realistic determinant of shareholder value on the Johannesburg Stock Exchange compared to other measures.

The efficient market hypothesis (EMH) asserts that financial markets are efficient, meaning that current market values of stocks incorporate all available information. This study examines the weak-form efficiency of Palestine Stock Exchange stocks using the indices returns from 2010 to 2022. The study used parametric tests (Augmented Dickey-Fuller (ADF) unit root, serial autocorrelation) and nonparametric tests (Phillips-Perron (PP) unit root, run test, variance ratio test). The findings of these tests provide insights into the behavior of the Palestine Stock Exchange market. The run test outcomes reveal a statistically significant pattern in the data for general, insurance, and service indices, with a p-value below the significance level. Furthermore, the unit root tests indicate statistical significance for all indices with 0.00 p-values and t-statistic below the critical values of –2.86 for level and intercept, and –3.14 for level, trend, and intercept, signifying that the indices returns are stationary. In addition, serial autocorrelation test show that the general and Al-Quds indices show statistically significant links between consecutive observations at all four lags. However, the insurance, investment, and services indices show statistically significant results on three lags. The variance ratio test results challenge the random-walk hypothesis for all indices except industry and insurance. With low probability values, a discernible, long-term, predictable pattern is evident in the Palestine Stock Exchange indices. The analysis reveals that Palestine Stock Exchange index returns exhibit nonrandom behavior, suggesting predictability and patterns in daily returns, indicating the possibility of exploiting market inefficiencies in investment strategies.

Although internal control systems in firms aim to provide reasonable assurance regarding objectives related to operations, reporting, and compliance, research focusing on operational efficiency is limited. This study investigates the impact of both quantitative and qualitative investments in internal control personnel on a firm’s operational efficiency. Utilizing a fixed-effect regression model, the Heckman (1979) two-stage model, and a two-stage least squares procedure, this study analyzes 4,471 firm-year observations from Korean listed firms from 2018 to 2020. The findings indicate a positive association between investment in internal control personnel and operational efficiency. This relationship remains robust even under sensitivity tests and concerns of potential endogeneity, as confirmed by the Heckman and two-stage least squares models. Specifically, the Heckman model shows that the ratio of the number of employees (coef = 0.023, t-value = 5.20) and certified public accountants (coef = 0.256, t-value = 5.43) responsible for internal control is positively associated with operational efficiency. Average work experience (coef = 0.002, t-value = 1.84) of internal control personnel is also positively related to operational efficiency. This study provides empirical evidence for the significance of investing in internal control personnel to boost operational efficiency and suggests that firms should consider both quantitative and qualitative aspects of internal control.
