In our sample of 99 countries over the period 1975–2020, increased activity of banks relative to markets in the provision of financial services is robustly associated with less inequality in the developing world yet with more inequality in developed economies. Accounting for redistribution systems does not alter this finding; banking sector concentration amplifies the effects. Results suggest that banks work at the extensive margin at earlier stages of economic development yet shift to the intensive margin at higher levels of development, where they increasingly serve the interests of the rich. Higher market power enables banks to better pursue their objectives at each of the margins.","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136351593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To contribute to this literature, this study analyzes whether democracy and economic freedom affect the banking sector in European Union member countries. We provide empirical evidence of the influence of democracy and economic freedom on banking performance using a sample of 27 countries from 2001 to 2020, and accounting‐based return on assets (ROA) and return on equity (ROE) as performance measures. A dynamic model (system GMM) was used to address issues such as heteroscedasticity, serial correlation, and endogeneity. These findings indicate that democracy is positively associated with banking performance, whereas economic freedom negatively affects it in the sample countries. Additionally, this study adds to the growing literature on the relationship between control variables (macroeconomic determinants, bank‐specific factors, or a country's legislative regime) and banking performance.

We also find that firms with a high level of institutional ownership and leverage experience a relatively lower drop in firms' values as a result of the mandatory CSR disclosures. These findings remain robust to alternative sampling design, use of market to book value as an alternative measure of firms' market‐based performance, and a parallel test to validate our DID analysis.

New empirical perspectives","authors":"Clement Olalekan Olaniyi, Mamdouh Abdulaziz Saleh Al‐Faryan, Eyitayo Oyewunmi Ogbaro","doi":"10.1002/ijfe.2900","DOIUrl":"https://doi.org/10.1002/ijfe.2900","url":null,"abstract":"Abstract The transition to renewable energy is critical for environmental sustainability, consistent with sustainable development goals (SDGs) 7, 8, 11, 12, and 13 of the United Nations Development Programme (UNDP). Scholars have identified financial development and institutional quality as significant factors determining the renewable energy transition in developing countries. This study opines that the efficiency of the financial system in supporting and providing the substantial financial implications that a switch to renewable energy necessitates depends on the quality of the institutional framework. Weak institutions in developing countries produce loopholes and inherent flaws in the financial system that facilitate corruption and opportunism, ultimately promoting dirty energy usage and technology at the expense of renewable energy. This process suggests that the interaction between financial development and institutions can either accelerate or impede the transition to renewable energy, depending on an economy's institutional architecture. Considering Africa's enormous renewable energy resources, previous research has overlooked the implications of the interplay between institutional quality and financial development in spurring Africa's transition to renewable energy. Thus, this study looks at the role of institutions in moderating the relationship between financial development and renewable energy in Africa from 1990 to 2019, using first‐ and second‐generation estimators to capture econometrics' pitfalls such as endogeneity, cross‐sectional dependence, and heterogeneity inherent in the panel dataset. This study departs from previous research in that it uses a dynamic panel threshold to determine the threshold of institutions beyond which financial development is stimulated to spur Africa's transition to renewable energy. The findings show that institutions create loopholes that allow rent‐seeking, opportunism, and sharp practices in the African financial system. These inherent flaws divert financial resources to support dirty energy and undermine the financial sector's ability to support a renewable energy transition on the continent. Also, the findings from the threshold of institutions affirm that African countries operate predominantly below the threshold of institutions, over which institutions enable financial development to expedite the continent's transition to renewable energy. The study suggests that institutional quality is essential in the relationship between financial development and Africa's shift to renewable energy. The findings' policy implications are discussed and outlined.","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135636674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing the DCC‐range GARCH model, we also explore the conditional minimum downside risk hedge ratios. Our findings demonstrate that confirmation bias leads to excessive EVaR for financial market returns, regardless of the period being before or during COVID‐19. Moreover, fundamentalists' expectations in all markets remain constant, while without confirmation bias, optimists' and pessimists' expectations tend to converge to zero over time but diverge significantly during turbulent periods. When confirmation bias is present, the average distance between these expectations widens. Analysing the hedge ratio results, with or without confirmation bias, also unveils the conditional minimum downside risk hedge ratios. These ratios indicate the optimal proportions for hedging downside risk in each financial market during different periods. We find that the conditional minimum downside risk hedge ratios are generally lower (higher) during the pre‐COVID‐19 (COVID‐19) period, implying that hedging costs are higher during the COVID‐19 period. These insightful findings offer valuable insights for traders and regulators in identifying and understanding the risk conditions of cryptocurrency, commodity, and stock markets. Additionally, the analysis of conditional minimum downside risk hedge ratios provides investors with essential information on how to strategically position their portfolios to mitigate and manage risk during both tranquil and turbulent market conditions, with and without confirmation bias.","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study undertakes an investment criteria investigation of institutional investors in Turkiye. The sample covers real and financial sector companies to investigate sectoral differences in Borsa Istanbul‐listed firms for 2010–2021. Using a panel data approach, we show that the presence of growth options, generous payout policy, attractive firm valuation, and quality of the external governance mechanisms are important factors in attracting institutional investors by real sector firms. Only a large firm size and the quality of the external governance mechanisms arise as important factors for financial sector firms. Moreover, institutional holdings positively impact the percentage shares of institutional investors during crisis periods among real sector firms, whereas they do not affect financial sector firms. Real‐sector and financial‐sector firms can use our findings to increase institutional ownership.

Papapostolou, Mahmoud Fatouh","doi":"10.1002/ijfe.2893","DOIUrl":"https://doi.org/10.1002/ijfe.2893","url":null,"abstract":"Abstract We develop a four‐state regime‐switching model for optimal foreign exchange (FX) hedging using forward contracts. The states correspond to four distinct market conditions, each defined by the direction and magnitude of deviation of the prevailing FX spot rate from its long‐term trends. The model's performance is evaluated for five currencies against the pound sterling for various horizons. Our examination compares the hedging outcomes of the proposed model to those of other commonly employed hedging methods. The empirical results suggest that our model demonstrates the highest level of risk reduction for the US dollar, euro, Japanese yen and Turkish lira and the second‐best performance for the Indian rupee. The risk reduction is significantly higher for lira compared with the other approaches, implying that the proposed model might be able to provide much more effective hedging for highly volatile currencies. The improved performance of the model can be attributed to the adjustability of the estimation horizon for the optimal hedge ratio based on the prevailing market conditions. This, in turn, allows it to better capture fat‐tail properties that are frequently observed in FX returns. Our findings suggest that FX investors tend to use short‐term memory during low market conditions (relative to trend) and long‐term memory in high ones. The results would be also useful to build a better understanding of how investor behaviour depends on market conditions and mitigate the adverse behavioural implications of short‐term memory, such as panic.","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134907004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is because the corporate board of a conglomerate‐affiliated firm (CAF) has high moral hazard exposure due to its accountability to the superior parent board at the apex of the conglomerate structure. Based on a sample of 304 listed firms from 18 countries, we find a CAF board is less independent than a standalone board with no superior reporting body. A firm's affiliation with the conglomerate per se affects its board independence, regardless of the parent shareholding level. The additional analysis finds that the lack of board independence significantly impacts a CAF's financial performance, although the market impact is insignificant.","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134902693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
