PurposeThis paper aims to investigate the effect of presidential elections on stock return volatility in five leading stock markets in sub-Saharan Africa.Design/methodology/approachThis paper uses various criteria to select an appropriate generalized autoregressive conditional heteroscedasticity model to estimate the second moment of the return distribution with the inclusion of pre- and post-presidential election dummy variables that capture the effect of presidential elections on stock market volatility.FindingsThe empirical results show that high pre-election uncertainty increases volatility in the Nairobi Stock Exchange, Stock Exchange of Mauritius and the Nigeria Stock Exchange. Furthermore, the results show that volatility in stock return is reduced 90 days after an election in Nigeria and South Africa but increases 90 days after elections in Ghana.Originality/valueContrary to the previous studies that are conducted in a single country with focus on specific elections, this paper provides a comparative analysis of presidential elections and stock return volatility in five leading stock markets in sub-Saharan Africa.
目的本文旨在研究撒哈拉以南非洲五个主要股票市场的总统选举对股票回报率波动的影响。设计/方法/方法本文使用各种标准选择了一个合适的广义自回归条件异方差模型来估计回报分布的二阶矩,其中包括总统选举后的虚拟变量,捕捉总统选举对股市波动的影响。实证结果表明,选举前的高度不确定性增加了内罗毕证券交易所、毛里求斯证券交易所和尼日利亚证券交易所的波动性。此外,结果显示,尼日利亚和南非的股票回报率在选举后90天降低,但在加纳的选举后90天后增加。Originality/value与之前在一个国家进行的专注于特定选举的研究相反,本文对撒哈拉以南非洲五个主要股票市场的总统选举和股票回报波动进行了比较分析。

PurposeThis study aims to examine the nexus among financial inclusion, legislative corporate social responsibility (CSR) and the financial performance of banking companies in India.Design/methodology/approachThe study uses the fixed-effect model to measure the impact of financial inclusion on the financial performance of banks listed in the Bank Nifty Index from 2015 to 2022. Furthermore, it examines the interaction effect of legislative CSR and financial inclusion on the performance of banks.FindingsThe study shows that financial inclusion indicators positively affect financial performance, which is critical for banking institutions. Empirically, the study provides evidence that legislative CSR is a significant moderator that can influence the relationship between financial inclusion and the financial performance of banks.Practical implicationsThe emerging nations may concentrate on implementing legislative CSR spending to achieve economic value for their firms and societal responsibility toward stakeholders.Originality/valueAs per the authors’ collective knowledge, this study is the one that extends the empirical evidence that the legislative CSR is a potential moderator which influences the relationship between financial inclusion and the performance of banks.
本研究旨在探讨金融普惠、立法企业社会责任(CSR)和印度银行公司财务绩效之间的关系。本研究使用固定效应模型来衡量2015年至2022年普惠金融对银行靓丽指数(Bank Nifty Index)所列银行财务绩效的影响。此外,本文还考察了立法企业社会责任和普惠金融对银行绩效的交互影响。研究结果表明,普惠金融指标对金融绩效有积极影响,这对银行机构至关重要。实证研究表明,立法企业社会责任是影响普惠金融与银行财务绩效关系的重要调节因子。实践启示:新兴国家可能会专注于立法实施企业社会责任支出,以实现企业的经济价值和对利益相关者的社会责任。原创性/价值根据作者的集体知识,本研究扩展了立法企业社会责任是影响金融普惠与银行绩效关系的潜在调节因素的经验证据。

PurposeThis study aims to investigate the dynamic interconnectedness of economic policy uncertainty (EPU), fiscal policy uncertainty (FPU) and monetary policy uncertainty (MPU) in four nations, the USA, Japan, Greece and South Korea, between 1998 and 2021.Design/methodology/approachTo comprehend the cross-category/cross-country evolution of uncertainty connectedness, the authors use the conditional connectedness approach. By using an inclusive network, this strategy lessens the bias caused by omitted variables. The TVP-VAR method is advantageous as it eliminates outliers that may potentially skew the results and reduces the bias caused by picking arbitrary rolling windows.FindingsBased on the findings, aggregate EPU is a net transmitter of policy uncertainties across all countries when conditional-country connectedness is used. MPU receives significantly more spillovers than FPU does across all countries, even though both are primarily recipients of uncertainties. The USA appears to be a transmitter of categorical spillovers before COVID-19, while Greece appears to be a net receiver of all category spillovers in terms of category-specific connectedness. The existence of extreme global events is also seen to cause an increase in category-specific and country-specific connectedness. Additionally, the authors report that conditional country-specific connectedness is greater than conditional category-specific connectedness.Originality/valueThis study expands existing literature in several ways. Firstly, the authors use a novel conditional connectedness approach, which has not been used to untangle cross-category/cross-country policy uncertainty connectedness. Secondly, they use the TVP-VAR approach which does not depend on rolling windows to understand dynamic connectedness. Thirdly, they use an expanded number of countries in their analysis, a departure from existing studies that have in most cases used two countries to understand categorical EPU connectedness.
目的本研究旨在调查1998年至2021年间美国、日本、希腊和韩国四个国家经济政策不确定性(EPU)、财政政策不确定性和货币政策不确定性的动态相互关系,作者使用了条件连通性方法。通过使用包容性网络,该策略减少了因遗漏变量而引起的偏差。TVP-VAR方法是有利的,因为它消除了可能使结果偏斜的异常值,并减少了由拾取任意滚动窗口引起的偏差。调查结果基于调查结果,当使用有条件的国家连通性时,总EPU是所有国家政策不确定性的净传递者。MPU在所有国家都比FPU获得了更多的溢出效应,尽管两者都是不确定性的主要接受者。在新冠肺炎之前,美国似乎是分类溢出的传播国,而希腊似乎是所有分类溢出的净接收国,就特定类别的连通性而言。极端全球事件的存在也被视为导致特定类别和特定国家的联系增加。此外,作者报告说,有条件的国家特定连通性大于有条件的类别特定连通性。原创性/价值这项研究以多种方式扩展了现有文献。首先,作者使用了一种新的条件连通性方法,该方法尚未用于解开跨类别/跨国政策的不确定性连通性。其次,他们使用TVP-VAR方法来理解动态连通性,该方法不依赖于滚动窗口。第三,他们在分析中使用了更多的国家,这与现有的研究不同,现有的研究在大多数情况下使用两个国家来理解EPU的分类连通性。

PurposeThis study aims to examine the impact of economic policy uncertainty and bank competition on the financial stability of the Chinese banking industry. This study answers two fundamental questions. First, does economic policy uncertainty (EPU) affects the financial stability of banks in China? Second, does competition affect the financial stability of the Chinese banking sector?Design/methodology/approachThe sample includes all commercial banks to provide a full picture of the Chinese banking sector. This study covers the time between 2011 and 2019. The sample period captures different EPU spikes and key policy changes. This study used different econometric methodologies such as the generalized method of moments and the fixed effect and ordinary least square estimation models. Furthermore, this study used the Instrumental Variable model to solve endogeneity, autocorrelation and unobserved heterogeneity concerns. Besides, alternative EPU and financial stability measures were used. Moreover, this study reestimates the model after dropping the big five state-owned banks.FindingsThis study found that both EPU and competition reduce financial stability. This implies that EPU has a negative impact on financial stability. This shows that uncertainty distorts resource allocation efficiency and creates confusion, leading to financial instability in the banking sector. Besides, this study found that competition negatively affects financial stability. This result implies that high competition pushes banks toward riskier activities that ultimately lead to increased financial instability.Originality/valueThis study is the first of its kind that examines the impact of EPU and competition on the financial stability of the Chinese banking sector. This study conducted several robustness tests such as the instrumental variable model, alternative measurement and sample construction methods. This study brings policy implications and lessons for the banking sector.
目的探讨经济政策不确定性和银行竞争对中国银行业金融稳定性的影响。这项研究回答了两个基本问题。第一,经济政策不确定性是否影响中国银行的金融稳定性?第二,竞争是否影响中国银行业的金融稳定?设计/方法/方法样本包括所有商业银行,以提供中国银行业的全貌。这项研究涵盖了2011年至2019年的时间。采样周期捕获不同的EPU峰值和关键策略变化。本研究采用了广义矩量法、固定效应和普通最小二乘估计模型等不同的计量经济学方法。此外,本研究使用工具变量模型来解决内生性、自相关性和未观察到的异质性问题。此外,还采用了替代性的EPU和金融稳定措施。此外,本研究在剔除五大国有银行后对模型进行了重新估计。研究发现EPU和竞争都会降低金融稳定性。这意味着EPU对金融稳定有负面影响。这表明,不确定性扭曲了资源配置效率,造成混乱,导致银行业的金融不稳定。此外,本研究发现竞争对金融稳定有负面影响。这一结果表明,激烈的竞争促使银行从事风险更高的活动,最终导致金融不稳定加剧。原创性/价值本研究首次探讨了EPU和竞争对中国银行业金融稳定性的影响。本研究进行了工具变量模型、替代测量方法和样本构建方法等稳健性检验。这项研究为银行业带来了政策启示和经验教训。

PurposeThis paper examines the time-varying return connectedness between renewable energy, oil, precious metals, the Gulf Council Cooperation region and the United States stock markets during two successive crises: the pandemic Covid-19 and the 2022 Russo-Ukrainian war. The main objective is to investigate the effect of the Covid-19 pandemic and the Russo-Ukrainian war on the connectedness between the considered stock markets.Design/methodology/approachThis paper uses the time-varying parameter vector autoregression approach, which represents an extension of the Spillover approach (Diebold and Yilmaz, 2009, 2012, 2014), to examine the time-varying connectedness among stock markets.FindingsThis paper reflects the effect of the two crises on the stock markets in terms of shock transmission degree. We find that the United States and renewable energy stock markets are the main net emitters of shocks during the global period and not just during the two considered crises sub-periods. Oil stock market is both an emitter and a receiver of shocks against Gulf Council Cooperation region and United States markets during the full sample period, which may be due to price fluctuation especially during the two crises sub-periods, which suggests that the future is for renewable energy.Originality/valueThis paper examines the effect of the two recent and successive crises, the Covid-19 pandemic and the 2022 Russo-Ukrainian war, on the connectedness among traditional stock markets (the United States and Gulf Council Cooperation region) and commodities stock markets (renewable energy, oil and precious metals).
本文考察了两次连续危机(2019冠状病毒病大流行和2022年俄乌战争)期间,可再生能源、石油、贵金属、海湾委员会合作地区和美国股市之间的时变回报连通性。主要目的是调查Covid-19大流行和俄乌战争对所考虑的股票市场之间连通性的影响。设计/方法/方法本文使用时变参数向量自回归方法,它代表了溢出方法的扩展(Diebold和Yilmaz, 2009, 2012, 2014),来检查股票市场之间的时变连通性。本文从冲击传导程度上反映了两次危机对股票市场的影响。我们发现,美国和可再生能源股票市场是全球时期冲击的主要净排放者,而不仅仅是在两个被认为是危机的子时期。在整个抽样期间,石油股票市场既是海湾理事会合作区域和美国市场受到冲击的排放者,也是受冲击者,这可能是由于价格波动,特别是在两个危机分时期,这表明未来属于可再生能源。本文考察了最近两次连续的危机,即新冠肺炎大流行和2022年俄乌战争,对传统股票市场(美国和海湾委员会合作地区)和大宗商品股票市场(可再生能源、石油和贵金属)之间的连通性的影响。

PurposeThe purpose of the current study is to identify variables that, when integrated into the random effects parametric survival model, could be used to forecast the failure rate of small banks in the USA. A bank’s income production, efficiency and costs were taken into consideration when choosing the internal components. The breakout of the financial crisis, bank regulations that affect how the banking sector operates and the federal funds rate are the primary external variables.Design/methodology/approachThis study uses the random effects parametric survival model to investigate the causes of small bank failures in the USA from 1996 to 2019. The study identifies several characteristics that failed banks frequently display. The main indications that may help to identify the elevated risk of small bank failures include the ROA, the cost of funds, the ratio of noninterest income to assets, the ratio of loan and lease losses to assets, noninterest expenses and core capital (leverage) ratio to assets. Economic disruptions, financial market distress and industry-based regulatory redress by the government exacerbate the financial distress borne by small banks.FindingsThe study revealed that a failed bank typically demonstrates a certain number of characteristics. The key factors that might assist identify which bank would be most likely to collapse include the cost of funding earning assets, the yield on earning assets, core Capital (leverage) ratio to assets, loan and lease loss provision to assets, noninterest expense and noninterest income to assets. Additionally, when a financial crisis occurs or the government changes regulations that could raise the cost of compliance for small banks, the likelihood that a bank will fail increases.Originality/valueModels based on survival theories are more suitable when the authors examine bank failure as a unique event that happens gradually. The authors use a random effects parametric survival model to investigate the internal and external factors that may influence prospective small bank failure. This model has been developed and used in the medicinal research field. The authors do not choose the Cox proportional hazards model because it does not work well with panel data.
本研究的目的是识别变量,当整合到随机效应参数生存模型中时,可以用来预测美国小银行的失败率。在选择内部组成部分时,考虑了银行的收入产出、效率和成本。金融危机的爆发、影响银行业运作的银行监管以及联邦基金利率是主要的外部变量。设计/方法/方法本研究使用随机效应参数生存模型调查1996年至2019年美国小银行倒闭的原因。这项研究指出了破产银行经常表现出的几个特点。可能有助于识别小银行破产风险升高的主要指标包括总资产收益率、资金成本、非利息收入与资产的比率、贷款和租赁损失与资产的比率、非利息支出和核心资本(杠杆)与资产的比率。经济动荡、金融市场困境和政府基于行业的监管补救加剧了小银行的财务困境。研究结果表明,一家倒闭的银行通常表现出一些特定的特征。可能有助于确定哪家银行最有可能倒闭的关键因素包括:盈利资产的融资成本、盈利资产的收益率、核心资本(杠杆)与资产的比率、贷款和租赁损失拨备与资产的比率、非利息费用和非利息收入与资产的比率。此外,当金融危机发生或政府改变监管规定,可能会提高小银行的合规成本时,银行倒闭的可能性就会增加。当作者将银行倒闭视为一个逐渐发生的独特事件时,基于生存理论的独创性/价值模型更合适。作者使用随机效应参数生存模型来研究可能影响预期小银行倒闭的内部和外部因素。该模型已在医学研究领域得到发展和应用。作者没有选择Cox比例风险模型,因为它不能很好地处理面板数据。

Economic disruptions, financial market distress and industry-based regulatory redress by the government exacerbate the financial distress borne by small banks.\u0000\u0000\u0000Findings\u0000The study revealed that a failed bank typically demonstrates a certain number of characteristics. The key factors that might assist identify which bank would be most likely to collapse include the cost of funding earning assets, the yield on earning assets, core Capital (leverage) ratio to assets, loan and lease loss provision to assets, noninterest expense and noninterest income to assets. Additionally, when a financial crisis occurs or the government changes regulations that could raise the cost of compliance for small banks, the likelihood that a bank will fail increases.\u0000\u0000\u0000Originality/value\u0000Models based on survival theories are more suitable when the authors examine bank failure as a unique event that happens gradually. The authors use a random effects parametric survival model to investigate the internal and external factors that may influence prospective small bank failure.

PurposeThe purpose of this paper is discussing on cross-city empirical economic growth, by estimating an unbalanced dynamic panel for the most vulnerable region of Brazil.Design/methodology/approachThe authors propose including additional and specific sources of cross-city variation, enabling them to capture the essence and reality of this region. The sample selection is given by the solution of a trade-off on the number of cities and the available explanatory variables. Considering the final choice, the analysis is based on 6,452 observations extracted from a sample of 925 cities between 2009 and 2015. Reconciling the regional growth literature and this availability of observable data, the authors decide to explain cross-city real gross domestic product per capita in log, controlling for its lagged value besides 15 explanatory variables on human capital, financial system, business environment and social infrastructure.FindingsThis study uses growth drivers on human capital, financial system, business environment and social infrastructure. Considering 6,452 observations for the period from 2009 to 2015, this study finds a significant role played by the levels of education of formal workers, rural financing, real estate financing and FIRJAN indices (health and employment).Research limitations/implicationsA more comprehensive and complete understanding of cross-city variation, whether in the Northeast, in the North of the country or in other regions, involves the expansion of growth drivers in the model. Certainly, the impact of the industrial sector (not captured by the FIRJAN employment/income index), or programs and initiatives geared to technology, must be significant and positive. Despite the low market share, the insertion of microcredit data for informal, small business owners and more underserved families, can bring insights not measured in this article.Practical implicationsOn financial system and development: The results on the significant and positive coefficient of rural and real estate financing are fundamental in conducting public policies aimed at granting credit. On human capital: The expected and intuitive relevant role of education suggests that good policies that are implementable need to be looked for and replicated to other northeastern cities. The state of Ceará seems to be that benchmark to be followed by the other states.Social implicationsAnother public policy that needs to be strengthened so that the most vulnerable cities can grow is related to the partnership with the private sector in the expansion and maintenance of basic sanitation. In this context, the new Legal Framework for Basic Sanitation is an important step. Its main objective is to universalize and qualify the provision of services in the sector. Theoretically, it seems to be an important advance and this also unlocks the first big wave of investments.Originality/valueThe analysis aims to contribute to the recent studies on regional g
目的本文的目的是通过估计巴西最脆弱地区的不平衡动态面板来讨论跨城市的实证经济增长。设计/方法/方法作者建议包括跨城市变化的额外和具体来源,使他们能够捕捉到该地区的本质和实际。样本选择是通过对城市数量和可用解释变量进行权衡的解决方案给出的。考虑到最终选择,该分析基于2009年至2015年间从925个城市样本中提取的6452个观测结果。在调和区域增长文献和可观察数据的可用性的基础上,作者决定用对数来解释跨城市的实际人均国内生产总值,并控制其滞后值,此外还有15个关于人力资本、金融系统、商业环境和社会基础设施的解释变量。研究结果本研究使用了人力资本、金融体系、商业环境和社会基础设施方面的增长驱动因素。考虑到2009年至2015年期间的6452个观察结果,本研究发现正规工人的教育水平、农村融资、房地产融资和FIRJAN指数(健康和就业)发挥了重要作用,在该国北部或其他地区,涉及模式中增长驱动力的扩张。当然,工业部门(FIRJAN就业/收入指数未涵盖)或面向技术的计划和举措的影响必须是显著和积极的。尽管市场份额较低,但为非正规、小企业主和服务不足的家庭插入小额信贷数据,可以带来本文无法衡量的见解。金融体系与发展的实际含义:农村和房地产融资显著正系数的结果是实施信贷公共政策的基础。关于人力资本:教育的预期和直观的相关作用表明,需要寻找可实施的好政策,并将其推广到东北其他城市。塞阿拉州似乎是其他州效仿的基准。社会影响需要加强的另一项公共政策是与私营部门在扩大和维护基本卫生方面的伙伴关系,以使最脆弱的城市能够发展。在这方面,新的基本卫生法律框架是一个重要步骤。其主要目标是使该部门的服务提供普遍化并符合资格。从理论上讲,这似乎是一个重要的进步,这也开启了第一轮投资浪潮。独创性/价值该分析旨在为最近应用于巴西的区域增长研究做出贡献。据作者所知,这是一个创新性的贡献,本文与其他论文的主要区别在于城市样本、时期、增长模型和估计技术。例如,Da Mata等人(20052007)探讨了1970年至2000年间123个城市群的人口增长及其对经济动态和创收的影响。Alves(2021)研究了1991年至2010年巴西272个城市当代城市化家庭中贫民窟的增长。

PurposeThis paper to identify those states that suffered the largest job losses, largest GDP declines and the highest unemployment rates and those states whose employment levels, unemployment rates and GDP declines were smallest during the COVID-19 recession. In addition, this paper endeavors to provide at least preliminary insights into why some states faired so poorly, whereas other states suffered so little during this downturn.Design/methodology/approachThis paper uses descriptive statistics and regression analysis to analyze the differences in state performance during the COVID-19 recession and recovery.FindingsThe results from the two estimated regression models suggest that where you lived determined the severity of the recession and living in a blue state negatively impacted the strength of state’s unemployment rate recovery.Research limitations/implicationsThis paper looks at only a two-year period starting with the COVID-19 recession and ending in December 2021.Practical implicationsThis paper provides a regional assessment of the COVID-19 recession and recovery on both a state and regional level.Social implicationsThe paper uses descriptive statistics to characterize the substantial state-level differences in the relative magnitude of economic decline due to the Covid-19 recession. Regression analysis reveals that blue states experienced weaker recovery as compared to red states.Originality/valueThe study uses publicly available data to identify states that suffered the largest job losses and highest peak unemployment rates during the Covid-19 recession. The results are among the first to analyze the economic impact of the Covid-19 recession at the state level.
本文旨在确定在2019冠状病毒病衰退期间失业人数最多、GDP下降幅度最大、失业率最高的州,以及就业水平、失业率和GDP下降幅度最小的州。此外,本文试图提供至少初步的见解,为什么一些州公平如此之差,而其他州遭受如此之少在这次经济衰退。设计/方法/方法本文使用描述性统计和回归分析来分析COVID-19衰退和复苏期间国家绩效的差异。两个估计回归模型的结果表明,你住在哪里决定了经济衰退的严重程度,而住在蓝州对该州失业率复苏的力度产生了负面影响。本文仅考察了从2019冠状病毒病衰退开始到2021年12月结束的两年时间。本文在州和地区层面对COVID-19的衰退和复苏进行了区域评估。社会影响本文使用描述性统计数据来描述因Covid-19经济衰退而导致的经济衰退相对幅度在各州之间的巨大差异。回归分析显示,与红色州相比,蓝色州经历了较弱的复苏。该研究使用公开数据来确定在2019冠状病毒病经济衰退期间失业人数最多和失业率最高的州。该研究结果是首批在州一级分析新冠肺炎衰退对经济影响的研究之一。

Unpleasant surprises? Debt relief and risk of sovereign default 不愉快的惊喜?债务减免和主权违约风险
IF 1.2 Q3 Economics, Econometrics and Finance Pub Date : 2023-01-06 DOI: 10.1108/jfep-12-2022-0294

PurposeThe Covid-19 pandemic has rekindled interest in sovereign debt crises amidst calls for debt relief for developing and emerging countries. But has debt relief lessened the debt burdens of emerging and developing economies? The purpose of this paper is to empirically address this question. In particular, the focus is on the implications of debt relief and institutional qualities for sovereign debt in emerging and developing economies.Design/methodology/approachThe model extends the framework on the probability of default by incorporating the receipt of debt relief by a debtor country. Doing so allows to better explain movements of sovereign defaults relating to debt relief. The model is estimated via the regular probit regression.FindingsThe analysis shows that the debt relief provided, thus, far, failed to ease the debt overhang problems of developing and emerging countries and reduced investment. The current debt relief schemes may underscore the prospects of self-enforcing and self-fulfilling sovereign debt crises rather than eliminating the dilemma completely. Regarding the forms of debt relief, the analysis shows that debt forgiveness offers favourable prospects in terms of debt sustainability and economic outcomes than debt rescheduling. Perhaps, the sovereign debt crises, particularly in low-income countries, hinge on insolvency problems rather than transitory illiquidity issues.Practical implicationsAny debt relief mechanism should consider seriously the potential incentive effect that reinforces expectations of future debt-relief initiatives. Importantly, solving the sovereign debt problem requires a programme for sustained investment and economic growth, while not discounting the critical role of prudent debt management policies and institutions.Originality/valueThis study contributes a different angle to the debate on sovereign debt distress. Aside from the structural and economic factors, this study investigates the role of debt management policy in the debtor nation and the implications of debt relief benefits for sovereign risk. The framework also focuses on whether the different forms of debt relief exert distinctive impacts.
在要求减免发展中国家和新兴国家债务的呼声中,2019冠状病毒病大流行重新引发了人们对主权债务危机的关注。但减免债务是否减轻了新兴和发展中经济体的债务负担?本文的目的是实证地解决这个问题。重点特别放在债务减免和机构性质对新兴和发展中经济体主权债务的影响上。设计/方法/方法该模型通过纳入债务国接受债务减免的情况,扩展了关于违约概率的框架。这样做可以更好地解释与债务减免有关的主权违约的走势。通过正则probit回归对模型进行估计。结果分析表明,迄今为止提供的债务减免未能缓解发展中国家和新兴国家的债务积压问题,并减少了投资。目前的债务减免计划可能突显出主权债务危机自我实施和自我实现的前景,而不是完全消除这种困境。关于债务减免的形式,分析表明,在债务可持续性和经济结果方面,债务减免比重新安排债务期限具有有利的前景。或许,主权债务危机,尤其是低收入国家的主权债务危机,取决于资不抵债问题,而不是暂时的流动性不足问题。任何债务减免机制都应认真考虑潜在的激励效应,这种效应会加强人们对未来债务减免举措的期望。重要的是,解决主权债务问题需要一个可持续投资和经济增长的计划,同时不低估审慎债务管理政策和机构的关键作用。本研究为主权债务危机的争论提供了一个不同的角度。除了结构和经济因素外,本研究还探讨了债务管理政策在债务国的作用以及债务减免利益对主权风险的影响。该框架还侧重于不同形式的债务减免是否会产生不同的影响。

COVID-19 related stringencies and financial market volatility: sectoral evidence from India 与COVID-19相关的紧缩措施和金融市场波动:来自印度的行业证据
IF 1.2 Q3 Economics, Econometrics and Finance Pub Date : 2022-12-20 DOI: 10.1108/jfep-05-2022-0136

PurposeThis study aims to examine the impact of the stringency of COVID-19 protocols on the volatility of sectoral indices during the period 03:2020–05:2021. Specifically, this study investigates the role of economic disturbances on sectoral volatility by applying a range of conditional volatility techniques.Design/methodology/approachFor this analysis, two approaches were adopted. The first approach considers COVID stringency as a factor in the conditional variance equation of sectoral indices. In contrast, the second approach considers the stringency indicator as a possible determinant of their estimated conditional volatility.FindingsResults show that the stringency of the protocols throughout the pandemic phase led to an instantaneous spike followed by a gradual decrease in estimated volatility of all the sectoral indices except pharma and health care. Specific sectors such as bank, FMCG, consumer durables, financial services, IT, media and private banks respond to protocols expeditiously compared to other sectors.Originality/valueThe key contribution of this study to the existing literature is the innovative approach. The inclusion of the COVID stringency index as a regressor in the variance equation of the conditional volatility techniques was a distinctive approach for assessing the volatility dynamics with the stringency of COVID protocols. Furthermore, this study also adopts an alternative approach that estimates the conditional volatility of the indices and then tests the effect of the stringencies on estimated volatility in a regression framework.
本研究旨在研究COVID-19协议的严格程度对03:2020-05:2021期间行业指数波动的影响。具体而言,本研究通过应用一系列条件波动率技术来调查经济扰动对部门波动率的作用。设计/方法/方法对于这个分析,采用了两种方法。第一种方法将COVID严格性作为部门指数条件方差方程中的一个因素。相比之下,第二种方法将严格性指标视为其估计条件波动的可能决定因素。结果表明,在整个大流行阶段,严格执行方案导致除制药和卫生保健外所有部门指数的估计波动率出现瞬时峰值,随后逐渐下降。与其他行业相比,银行、快速消费品、耐用消费品、金融服务、IT、媒体和私人银行等特定行业对协议的响应速度更快。独创性/价值本研究对现有文献的关键贡献在于其创新的研究方法。将COVID严格性指数作为回归因子纳入条件波动率技术的方差方程是评估COVID协议严格性波动动力学的一种独特方法。此外,本研究还采用了一种替代方法,即估计指数的条件波动率,然后在回归框架中测试严格程度对估计波动率的影响。
