This research highlights the asymmetric interdependence structure among the sovereign risks of Brazil, Russia, India, China, Indonesia, and Türkiye (BRICIT) nations, challenging the traditional view that bilateral trade is the main channel for cross-border spillover effects. Despite their dependence on Russian crude oil imports for energy, the BRICIT nations show no significant sovereign risk interdependence with Russia. The study finds that Indonesia's credit default swap (CDS) has the highest level of interdependence with other nations. Further exploration of alternative transmission channels necessitates an examination of the country risk premium, revealing Türkiye as the most vulnerable nation due to its negative association with the CDS of other countries, particularly India. By contrast, India is identified as a preferred investment destination, thanks to its lower uncertainty and strong GDP growth over the past decade. Additionally, the research underscores China's economic influence, demonstrated by its positive association with all other BRICIT nations. This suggests that despite the high sovereign risk associated with China, investors do not view other emerging markets as viable, lower-risk alternatives. The perceived risk related to China appears to extend beyond its borders, impacting the sovereign risk profiles of other emerging economies.

本研究强调了巴西、俄罗斯、印度、中国、印度尼西亚和土耳其（金砖四国）主权风险之间的非对称相互依存结构，挑战了双边贸易是跨境溢出效应主要渠道的传统观点。尽管 "金砖四国 "的能源依赖于俄罗斯的原油进口，但它们与俄罗斯之间并不存在显著的主权风险相互依存关系。研究发现，印度尼西亚的信用违约掉期（CDS）与其他国家的相互依存程度最高。由于土耳其与其他国家（尤其是印度）的信用违约掉期存在负相关，因此土耳其是最脆弱的国家。相比之下，印度因其较低的不确定性和过去十年强劲的国内生产总值增长而被视为首选投资目的地。此外，研究还强调了中国的经济影响力，中国与所有其他金砖四国的正相关关系就证明了这一点。这表明，尽管中国的主权风险较高，但投资者并不认为其他新兴市场是可行的、风险较低的替代选择。与中国相关的预期风险似乎已经超越了中国的国界，影响到其他新兴经济体的主权风险状况。

The purpose of this study is to analyze the impact of fund management companies' past performance, fees, perceived religiosity, and perceived risk on Malaysian Muslim investors' attitude toward them. The moderating effects of investor risk aversion, price sensitivity, religiosity, and Islamic financial literacy are considered. A model based on the unified theory of acceptance and use of technology is built to analyze the impact of the variables considered. The study data were collected using a survey of 550 Malaysian retail investors. Our findings show that Muslim investor attitudes are negatively affected by the perceived risk of a fund management company and positively affected by a fund management company's perceived religiosity and past performance. Moreover, the perceived religiosity impact is positively moderated by an investor's Islamic financial literacy and negatively moderated by the investor's price sensitivity. Practical implications of the results and avenues for further investigation in future research are discussed.

本研究旨在分析基金管理公司的过往业绩、费用、宗教信仰和风险对马来西亚穆斯林投资者态度的影响。研究还考虑了投资者风险规避、价格敏感性、宗教信仰和伊斯兰金融知识的调节作用。在接受和使用技术的统一理论基础上，建立了一个模型来分析所考虑的变量的影响。研究数据是通过对 550 名马来西亚散户投资者的调查收集的。我们的研究结果表明，穆斯林投资者的态度受到基金管理公司感知风险的负面影响，而受到基金管理公司感知宗教性和过往业绩的正面影响。此外，投资者的伊斯兰金融知识对感知宗教信仰的影响有正向调节作用，而投资者的价格敏感性对感知宗教信仰的影响有负向调节作用。本文讨论了研究结果的实际意义以及未来研究的进一步调查途径。

Stakeholders have become increasingly interested in sustainable practices, leading to intense investigation in the literature of their effects on companies' returns. However, not much information is available about the effect of environmental, social, and governance (ESG) controversy on companies' financial performance. Inappropriate social behavior and environmental scandals attract attention in the media and, consequently, among investors. Therefore, this study analyzes the impact of ESG controversy on companies' return on equity, identifying differences between companies that operate in different clusters such as environmentally sensitive industries (ESI) or non–environmentally sensitive industries and emerging/developed countries. To this end, we investigate 625 publicly owned companies for the period 2011 to 2022, using a four-dimensional hierarchical linear regression model, comprising time, firms, industries, and countries. ESG controversies negatively impact the financial performance of companies operating in ESI and developed countries.

利益相关者对可持续发展实践的兴趣与日俱增，从而导致文献中对其对公司回报影响的深入研究。然而，关于环境、社会和治理（ESG）争议对公司财务业绩影响的信息却不多。不当的社会行为和环境丑闻会引起媒体的关注，进而引起投资者的关注。因此，本研究分析了环境、社会和治理争议对公司股本回报率的影响，并确定了在环境敏感行业（ESI）或非环境敏感行业以及新兴国家/发达国家等不同集群中运营的公司之间的差异。为此，我们使用一个由时间、公司、行业和国家组成的四维分层线性回归模型，对 2011 年至 2022 年期间的 625 家上市公司进行了调查。ESG争议对在ESI和发达国家运营的公司的财务业绩产生了负面影响。

Banks play a pivotal role in the financial sector, assuming critical functions such as facilitating the monetary policy transmission mechanism and acting as intermediaries between savers and borrowers. Meanwhile, oil represents a fundamental input for economic activities, and its inherent volatility serves as a significant catalyst for economic instability. Given the critical roles of banking institutions and oil in the economy, their relationship garners attention from various stakeholders. The growing body of literature has examined the nexus between oil and banking performance. However, existing research has predominantly concentrated on either oil-exporting jurisdictions or country-specific analyses. Hence, the present study endeavors to bridge this gap in the literature by investigating the intricate dynamics between oil and banking performance, specifically in net oil-importing countries. The dynamic panel method is employed. The findings indicate that oil has direct and indirect effects on the profitability of banks operating through transmission channels.

银行在金融部门发挥着举足轻重的作用，承担着促进货币政策传导机制和充当储蓄者与借款者之间的中介等重要职能。同时，石油是经济活动的基本投入，其固有的波动性是经济不稳定的重要催化剂。鉴于银行机构和石油在经济中的关键作用，它们之间的关系引起了各利益相关方的关注。越来越多的文献研究了石油与银行业业绩之间的关系。然而，现有研究主要集中在石油出口辖区或具体国家的分析上。因此，本研究通过调查石油与银行业业绩之间错综复杂的动态关系，特别是石油净进口国的情况，努力弥补文献中的这一空白。本研究采用了动态面板法。研究结果表明，石油通过传导渠道对银行的盈利能力产生直接和间接的影响。

This study examines the impact of the institutional environment and corporate governance structures on Islamic banks' sustainability performance (SP). It applies a two-step System Generalized Method of Moments (GMM) estimator to analyze data gathered on a panel of 32 Islamic banks drawn from nine key Islamic finance jurisdictions from 2016 to 2021. To consistently code and quantify the Islamic banks' SP, we use the Specific Standard Disclosures for the Financial Services Sector introduced by the GRI as a framework of reference. Then, we employ the weighted content analysis method on the sustainability and annual reports of the subjected sample. Our findings indicate that the institutional factors specifically, regulatory guidelines (regulatory isomorphism) and the adherence of Islamic banks to the sustainable finance networks' specifications (normative isomorphism) are not currently determinants of their SP. Contrarily, we observe that the establishment of a sustainability committee and a better experience of sustainability disclosure improve Islamic banks' SP. In contrast to agency theory, board activity is identified to have a significantly negative relationship with SP. An important policy implication of our results is that policymakers should closely monitor Islamic banks' regulatory dependency and enhance their SF ecosystem to positively influence their SP. Finally, future research may leverage on more conducive regulatory frameworks to sustainability transition in these key jurisdictions, more effective normative structures, further disclosure of sustainability committee characteristics, the development of appropriate measures of Islamic banks' digitalization levels, and the availability of more material sustainability data to provide further insights and better understand the determinants of Islamic banks’ SP.

本研究探讨了制度环境和公司治理结构对伊斯兰银行可持续发展绩效（SP）的影响。它采用两步系统广义矩法（GMM）估计法，分析了从 2016 年到 2021 年从九个主要伊斯兰金融管辖区收集的 32 家伊斯兰银行的面板数据。为了对伊斯兰银行的 SP 进行统一编码和量化，我们使用 GRI 推出的金融服务行业特定标准披露作为参考框架。然后，我们采用加权内容分析法对样本的可持续发展报告和年度报告进行分析。我们的研究结果表明，制度因素，特别是监管准则（监管同构）和伊斯兰银行对可持续金融网络规范的遵守（规范同构）目前并不是其可持续发展报告的决定因素。相反，我们观察到，可持续发展委员会的成立和可持续发展信息披露方面的更多经验提高了伊斯兰银行的可持续发展能力。与代理理论相反，我们发现董事会活动与可持续发展战略有显著的负相关关系。我们的研究结果的一个重要政策含义是，政策制定者应密切关注伊斯兰银行的监管依赖性，并加强其可持续发展生态系统，从而对其可持续发展战略产生积极影响。最后，未来的研究可以利用这些主要司法管辖区更有利于可持续发展转型的监管框架、更有效的规范结构、进一步披露可持续发展委员会的特征、制定适当的伊斯兰银行数字化水平衡量标准，以及提供更多实质性的可持续发展数据，以提供进一步的见解，更好地理解伊斯兰银行可持续发展战略的决定因素。

Export credits are used extensively throughout the world to temper the negative effects of financial constraints on exports. In this paper, we focus on a particular form of subsidized export credits, namely, an export rediscount credit program implemented by the Central Bank of the Republic of Türkiye. For this purpose, we create a detailed firm-level data set that matches monthly firm-level export data with credit and financial statement data. Our results show that exports by firms that use rediscount credit increase significantly over a six-month horizon and that the amount of credit and export growth have a positive relation. Moreover, the relation between the credit amount and export volume is not linear; the correlation starts to decline after a certain point. Our results also reveal heterogeneity with respect to size: exports increase more after using rediscount credit for small firms than large firms.

出口信贷在世界各地被广泛使用，以缓解金融限制对出口的负面影响。在本文中，我们将重点关注一种特殊形式的补贴出口信贷，即由土耳其共和国中央银行实施的出口再贴现信贷计划。为此，我们创建了一个详细的企业级数据集，将每月的企业级出口数据与信贷和财务报表数据相匹配。我们的研究结果表明，使用再贴现信贷的企业的出口在 6 个月的期限内大幅增长，信贷额度与出口增长呈正相关。此外，信贷额度与出口量之间并非线性关系；相关性在达到一定程度后开始下降。我们的研究结果还揭示了企业规模的异质性：小企业在使用再贴现信贷后的出口增长幅度大于大企业。

This paper explores how systematic higher order moments (co-skewness and co-kurtosis) are priced in Borsa Istanbul. We tested the significance of higher order co-moments and analyzed their contribution to the standard capital asset pricing model and the Fama and French (2015) 5-factor model. We used a two-stage method to analyze the weekly returns of beta and size-sorted portfolios and individual stocks over the sample period from June 22, 2007 to November 15, 2023. We also used models conditional on market movements. The findings reveal that co-skewness has statistically significant effects on portfolio returns in Borsa Istanbul, especially in up markets. We also present the statistically significant effects of co-kurtosis on individual stock returns in both up and down markets.

The goal of building a diversified portfolio is to mitigate risks and manage risk-reward tradeoffs. Diversification is also crucial for ensuring the long-term success of a portfolio. Although passive investment has been on the rise in most developed markets, it has not gained wider acceptance in some emerging markets, such as Türkiye. This study proposes an approach to construct a diversified portfolio that serves as a passive investment tool in the context of the Turkish stock market. Despite the long history of equity markets in Türkiye, almost all available passive investment alternatives are prohibitively expensive, unlike those in developed markets. We design a simple methodology that addresses the essential components of building a successful portfolio while avoiding excessive fees. Additionally, we propose a dynamic balancing strategy that algorithmically adjusts the weight of each stock in the portfolio. We test this approach with historical data, demonstrating that it can achieve reasonable returns with minimal effort. Even when its performance does not beat the benchmark, the percentage deviation is still below the management fees charged for alternative investments.

建立多元化投资组合的目的是降低风险和管理风险回报权衡。分散投资对于确保投资组合的长期成功也至关重要。虽然被动投资在大多数发达市场呈上升趋势，但在一些新兴市场，如土耳其，还没有得到更广泛的接受。本研究以土耳其股市为背景，提出了一种构建多元化投资组合的方法，作为一种被动投资工具。尽管土耳其股票市场历史悠久，但与发达市场不同的是，几乎所有可用的被动投资工具都过于昂贵。我们设计了一种简单的方法，既解决了建立成功投资组合的基本要素，又避免了过高的费用。此外，我们还提出了一种动态平衡策略，通过算法调整投资组合中每只股票的权重。我们用历史数据对这一方法进行了测试，证明它能以最小的投入获得合理的回报。即使其业绩没有超过基准，偏差百分比仍低于另类投资的管理费。

The objective of this study is to examine the return interconnectedness and asymmetric spillover effects in global commodity futures markets, with a focus on the impact of contagion. A competent asymmetric time-varying parameter vector autoregressive (TVP-VAR) model was employed for highly traded commodity futures (cocoa, coffee, corn, cotton, soy, sugar, wheat, and oil) between January 1, 2000, and March 31, 2024. This study investigates the connectedness of commodities in three dimensions: asymmetric spillovers, the influence of oil and oil substitutes on the network, and the impact of major contagions. The average total connectedness index (TCI) indicates that the connectedness is significant throughout the period and increases during the invasion. The findings imply that contagion effects trigger a potential alteration in the structure of the network integration level of the commodities, amplifying system-wide dynamic connectivity due to disurptions caused by oil and oil substitutes. The net plot depicts corn and soy as the net transmitters, with their magnitude increasing during the contagions. The pairwise connectedness index (PCI) revealed that corn-soy, corn‒wheat, and soy-wheat were the primary interactors, while oil became a significant interactor, particularly during the oil crash and the COVID-19 outbreak. Additionally, compared with other contagions, GFC had a potential asymmetric effect on the network. Positive returns dominate the interaction between the primary transmitter and receivers, whereas negative returns do not significantly dominate the total network. These investigations contribute to the literature on the food-fuel nexus in terms of asymmetries and the impact of contagions on the futures market.

本研究的目的是考察全球商品期货市场的回报相互关联性和非对称溢出效应，重点关注传染的影响。针对 2000 年 1 月 1 日至 2024 年 3 月 31 日期间交易量较大的商品期货（可可、咖啡、玉米、棉花、大豆、糖、小麦和石油），采用了一个合格的非对称时变参数向量自回归（TVP-VAR）模型。本研究从三个方面考察了商品的关联性：非对称溢出效应、石油和石油替代品对网络的影响以及重大传染病的影响。平均总连通性指数（TCI）表明，连通性在整个时期都很显著，并且在入侵期间会增加。研究结果表明，传染效应会引发商品网络一体化水平结构的潜在变化，从而放大石油和石油替代品造成的全系统动态连通性。网状图显示，玉米和大豆是网状传播者，在疫情期间，它们的传播量不断增加。成对连通性指数（PCI）显示，玉米-大豆、玉米-小麦和大豆-小麦是主要的相互作用者，而石油则成为重要的相互作用者，尤其是在石油暴跌和 COVID-19 爆发期间。此外，与其他传染病相比，全球金融危机对网络产生了潜在的不对称影响。正回报在主要传播者和接收者之间的互动中占主导地位，而负回报在整个网络中的主导地位并不明显。这些研究从非对称性和传染病对期货市场的影响方面为有关粮食与燃料关系的文献做出了贡献。该研究还根据三种投资组合构建策略的对冲效果确定了最佳投资组合配置。

A competent asymmetric time-varying parameter vector autoregressive (TVP-VAR) model was employed for highly traded commodity futures (cocoa, coffee, corn, cotton, soy, sugar, wheat, and oil) between January 1, 2000, and March 31, 2024. This study investigates the connectedness of commodities in three dimensions: asymmetric spillovers, the influence of oil and oil substitutes on the network, and the impact of major contagions. The average total connectedness index (TCI) indicates that the connectedness is significant throughout the period and increases during the invasion. The findings imply that contagion effects trigger a potential alteration in the structure of the network integration level of the commodities, amplifying system-wide dynamic connectivity due to disurptions caused by oil and oil substitutes. The net plot depicts corn and soy as the net transmitters, with their magnitude increasing during the contagions. The pairwise connectedness index (PCI) revealed that corn-soy, corn‒wheat, and soy-wheat were the primary interactors, while oil became a significant interactor, particularly during the oil crash and the COVID-19 outbreak. Additionally, compared with other contagions, GFC had a potential asymmetric effect on the network. Positive returns dominate the interaction between the primary transmitter and receivers, whereas negative returns do not significantly dominate the total network. These investigations contribute to the literature on the food-fuel nexus in terms of asymmetries and the impact of contagions on the futures market.

This study quantifies the shock transmission mechanism between the trade policy uncertainty (TPU) index and Sharia-compliant stock sectoral conditional volatility in the Gulf Cooperation Council (GCC) countries. We employ a comprehensive analysis that includes the time-domain extended joint and frequency-domain quantum vector autoregressive (QVAR) frameworks. The time-domain QVAR demonstrates that TPU causes the most substantial shocks to utility sector volatility. Investors in the GCC must strategically allocate their investment portfolios to the consumer services and energy industries, which are less vulnerable to the TPU shock. The results show that TPU shocks provide more error variances to the long-term and bullish conditional volatility (or higher quantiles) of the utility, real estate investment trust funds (REIT), healthcare, and industry sectors. Conversely, during bearish volatility conditions (lower quantiles), TPU shocks result in higher shocks in the conditional volatility of the utility, REIT, finance, and industrial sectors. Long-term investors should diversify their portfolios to mitigate risk in the utility, REIT, and industry sectors through strategic investments in consumer service sector. However, in the short term and during both bearish and bullish sectoral volatility, the consumer service and industry sectors are more vulnerable to TPU shocks. Regarding diversity, the REIT, energy, and financial sectors are the least affected by TPU shocks, offering a protective buffer in the short term and during periods of higher and lower GCC Islamic sectoral volatility.

本研究量化了海湾合作委员会（GCC）国家贸易政策不确定性（TPU）指数与符合伊斯兰教法的股票行业条件波动性之间的冲击传导机制。我们采用了包括时域扩展联合和频域量子向量自回归（QVAR）框架在内的综合分析方法。时域量子向量自回归分析表明，TPU 对公用事业部门的波动性造成的冲击最大。海湾合作委员会的投资者必须战略性地将其投资组合分配到消费服务和能源行业，这些行业受 TPU 冲击的影响较小。研究结果表明，TPU 冲击为公用事业、房地产投资信托基金（REIT）、医疗保健和工业行业的长期和看涨条件波动率（或较高的量化值）提供了更多的误差方差。相反，在看跌的波动率条件下（较低的量化值），TPU 冲击会导致公用事业、房地产投资信托基金、金融和工业部门的条件波动率受到较大冲击。长期投资者应分散投资组合，通过对消费服务行业的战略投资来降低公用事业、房地产投资信托和工业行业的风险。然而，从短期来看，无论是在看跌还是看涨的行业波动中，消费服务和工业行业都更容易受到 TPU 的冲击。在多样性方面，房地产投资信托、能源和金融行业受 TPU 冲击的影响最小，在短期内以及海湾合作委员会伊斯兰行业波动较大和波动较小的时期都能提供保护性缓冲。
