This paper used two frames based on the Multivariate General Autoregressive Conditional Heteroscedasticity (MGARCH) model, namely the Dynamic Conditional Correlation (DCC) and the Baba, Engle, Kraft, and Kroner (BEKK) models. DCC parameters confirmed the significant results to assess the spillover effects for return volatilities of five cryptocurrencies (Bitcoin, Dogecoin, Ethereum, Monero, and Peercoin). It indicated that cryptocurrency market returns would be volatile, connected with the time-varying pattern. Most ARCH and GARCH effects were significant in estimating the three pairs of return-mining profitability, return-Tweet, and mining profitability-Tweet. For the cryptocurrency return and profitability pair, returns depended on future price returns and cross-volatility spillover and were greater than their own volatility spillover effect. Moreover, the BEKK diagonal model was found to be the best model for return-mining profitability. The research community can also gain valuable insights into cryptocurrency investment models, offering wider future areas of research.
本文采用了基于多元一般自回归条件异方差(MGARCH)模型的两种框架,即动态条件相关(DCC)模型和Baba, Engle, Kraft, and Kroner (BEKK)模型。DCC参数证实了评估五种加密货币(比特币、狗狗币、以太坊、门罗币和Peercoin)回报波动的溢出效应的重要结果。它表明,加密货币市场的回报将是不稳定的,与时变模式有关。大多数ARCH和GARCH效应在估计回报-挖矿盈利能力、回报-推特和挖矿盈利能力-推特三对时显著。对于加密货币收益和盈利能力对,收益取决于未来价格收益和交叉波动溢出效应,且大于其自身波动溢出效应。此外,发现BEKK对角模型是回报采矿盈利能力的最佳模型。研究界还可以获得有关加密货币投资模型的宝贵见解,从而提供更广泛的未来研究领域。

The impact of unconventional monetary policies adopted by advanced economies in the wake of the Global Financial Crisis has had far reaching implications for global economic conditions. Although several transmission channels of quantitative easing to financial market and exchange rate conditions have been identified, there is a lack of empirical investigation on the spillover effects to exports for emerging market economies. The research presented in this paper focuses on assessing the asymmetric transmission of unconventional monetary policy in the US on exports for fifteen emerging market economies. Employing the panel ARDL (Autoregressive Distributed Lag) model, we find that the increase in large-scale asset purchases in the US corresponds to a decline in exports in the emerging market economies. The effect on exports is more sizable in the Fragile Five than in the other 10 emerging markets. Finally, although monetary policy shocks from the US transmit to impact trade in emerging markets, the effect is asymmetric. Specifically, the tapering of the quantitative easing does not have a statistically significant effect on exports.

发达经济体在全球金融危机后采取的非常规货币政策对全球经济状况产生了深远影响。虽然已经确定了量化宽松对金融市场和汇率状况的几个传导渠道,但缺乏对新兴市场经济体出口溢出效应的实证调查。本文的研究重点是评估美国非常规货币政策对15个新兴市场经济体出口的不对称传导。采用面板ARDL(自回归分布滞后)模型,我们发现美国大规模资产购买的增加对应于新兴市场经济体出口的下降。与其他10个新兴市场相比,“脆弱五国”的出口受到的影响更大。最后,尽管来自美国的货币政策冲击会传导至新兴市场的贸易,但这种影响是不对称的。具体而言,量化宽松的缩减对出口没有统计学意义上的显著影响。

In this paper, we introduce a model for the prognosis of profit of an enterprise taking into account several types of products. Also, we introduce an approach for maximization of the considered profit with an analytical approach for estimation of the maximum value of profit of an enterprise taking into account several types of products. Profit maximization gives a possibility to take into account changes in the price of products on the market. As an example, we consider the estimation of profit for the accounting of three types of products. But the introduced approach gives a possibility to change a number of products.

This study is the first to empirically examine the linkage between e-Government and financial development. We utilize three indicators, including user centricity, business mobility, and key enablers to capture a digital process in the public sector, and their effects are analyzed on financial markets, institutions, and both. By employing an international sample of 26 European countries, we demonstrate the positive impacts of e-Government, especially the user centricity on the financialization. Furthermore, e-Government has the strongest influence on financial institutions.
本研究首次对电子政务与金融发展之间的联系进行实证研究。我们利用三个指标,包括以用户为中心、业务移动性和关键促成因素来捕捉公共部门的数字化流程,并分析其对金融市场、机构和两者的影响。本文以欧洲26个国家为样本,实证了电子政务特别是用户中心对金融化的积极影响。电子政务对金融机构的影响最大。

THE SPILLOVER, RISK AND LEVERAGE EFFECTS OF SMART BETA MANAGEMENT EXCHANGE-TRADED FUND (ETF) 智能贝塔管理型交易所交易基金的溢出效应、风险效应和杠杆效应
IF 0.7 Q3 Economics, Econometrics and Finance Pub Date : 2022-01-06 DOI: 10.1142/s2194565921500160

This research uses two different GARCH models to measure spillover, risk, and leverage effects of active, passive, and smart beta management Exchange-traded Funds (ETFs). The increase in popularity of ETFs and new categories within them, specifically the growth of smart beta management, means asset managers and investors have new metrics to account for when determining portfolio exposure following the Adaptive Investment Approach (AIA). The results show significant relationships among all groups regarding the spillover. A trend of positive multi-lateral spillover of returns among the three management types including passive, active and small beta is observed with smart beta showing the highest percentage of a bi-lateral positive effect. The strongest spillover of volatility effects is among the actively managed ETFs. The testing of risk results is insignificant, but the leverage effect results are consistent with the past studies showing the significant negative bi-lateral effect.
本研究使用两种不同的GARCH模型来衡量主动、被动和智能贝塔管理的交易所交易基金(etf)的溢出效应、风险和杠杆效应。etf和其中的新类别越来越受欢迎,特别是智能贝塔管理的增长,意味着资产管理公司和投资者在根据适应性投资方法(AIA)确定投资组合敞口时,有了新的指标需要考虑。结果表明,各群体在溢出效应方面存在显著的相关性。在包括被动、主动和小贝塔在内的三种管理类型中,观察到积极的多边回报溢出趋势,其中智能贝塔显示出双边积极效应的最高百分比。波动性溢出效应最强烈的是主动型etf。风险结果的检验不显著,但杠杆效应结果与以往的研究一致,显示出显著的负双向效应。

HOW THE EXCHANGE RATE REGIME AFFECTS ADJUSTMENT TO LARGE OIL PRICE SWINGS IN OIL EXPORTING COUNTRIES 汇率制度如何影响石油出口国对油价大幅波动的调整

The aim of this study is to analyze how oil price shocks affect the economic growth of floating exchange rate regimes and fixed exchange rate regimes in oil-exporting countries with a ratio of oil exports to total exports exceeding 70%. Also, this study seeks to determine what monetary and fiscal policies both regimes apply in order to curb business cycles and reduce inflationary and recessionary gaps. The analytical study uses panel data for the period from 1991 to 2019, covering 24 oil-exporting countries, from the World Economic Outlook (WEO) database and World Bank. The econometric model is estimated by applying a panel VECM to examine the short- and long-term interdependencies in the macroeconomic variables. The results demonstrate that when there is a negative shock to the oil price, the exchange rate of the floating exchange rate regimes depreciates, money supply increases, and government spending decreases. In contrast, the exchange rate of the fixed exchange rate regimes fluctuates slightly; the money supply slightly decreases in the near, medium, and long term; and government spending decreases.
本研究的目的是分析石油出口占总出口比重超过70%的石油出口国在浮动汇率制和固定汇率制下,油价冲击对经济增长的影响。此外,本研究还试图确定两种制度采用何种货币和财政政策,以抑制商业周期并减少通货膨胀和衰退差距。该分析研究使用了1991年至2019年期间的面板数据,涵盖了24个石油出口国,数据来自世界经济展望数据库和世界银行。计量经济模型是通过应用面板VECM来检查宏观经济变量的短期和长期相互依赖性来估计的。结果表明,当油价受到负冲击时,浮动汇率制下的汇率贬值,货币供应量增加,政府支出减少。相比之下,固定汇率制的汇率波动较小;货币供应量在近期、中期和长期均略有减少;政府开支减少。

This paper examines the effects of gender board diversity on working capital. The study uses a sample of S&P1500 firms, resulting in 9,157 firm-year observations from 2005 to 2019. Our findings show that greater gender diversity on corporate boards is associated with lower liquidity ratios, including lower non-cash ones. The results are robust to a battery of gender board diversity definitions and to a 2SLS analysis which employs the gender ratio in the county’s population in which the firm is headquartered as an instrumental variable. Based on additional tests of the effects of gender board diversity on managerial efficiency ratios, we conclude that the results are driven by superior monitoring associated with gender diversity on the board.
本文考察了董事会性别多样性对营运资金的影响。该研究使用了标准普尔1500公司的样本,得出了从2005年到2019年的9157个公司年观察结果。我们的研究结果表明,公司董事会性别多元化程度越高,流动性比率越低,包括非现金比率也越低。对于性别董事会多样性的一系列定义,以及采用公司总部所在县的人口性别比例作为工具变量的2SLS分析,结果都是稳健的。基于对董事会性别多样性对管理效率比率影响的额外测试,我们得出结论,这些结果是由与董事会性别多样性相关的卓越监控推动的。

The question of whether private and public consumption are complements or substitutes has been an issue of concern and hence, attracted the attention of researchers and policy think tanks. This study therefore investigates this important phenomenon within the context of sub-Saharan Africa (SSA) to inform the design of fiscal policy measures. Using panel data spanning the period 1981–2016 for 21 sub-Saharan African countries, the results indicate that, government and private consumption are substitutes. This indicates that government spending crowds out private consumption in the sub region. Vital policy implications have been provided for consideration based on the findings.
私人消费和公共消费是互补还是替代的问题一直是一个令人关注的问题,因此引起了研究人员和政策智库的注意。因此,本研究在撒哈拉以南非洲(SSA)的背景下调查这一重要现象,为财政政策措施的设计提供信息。利用1981-2016年21个撒哈拉以南非洲国家的面板数据,结果表明,政府和私人消费是替代的。这表明该次区域的政府支出挤占了私人消费。根据调查结果提出了重要的政策影响,供审议。

This paper investigates the effects of global economic sanctions (GESs) on global bank linkages (GBLs) by using 4,032 pairs of 66 countries during the 2001–2013 period. We use the structural gravity model combining with the rich database of the Global Sanction Data Base introduced by Felbermayr et al. [(2020). The global sanctions data base. European Economic Review, 129, 1–23]. Our empirical results show a negative association between the GESs and GBLs. The differential effects of GESs on the GBLs are conditional on the sanction types. Furthermore, the consequences of global sanctions become more severe for countries featuring higher information asymmetries, captured either by a high level of world uncertainty, an occurrence of crisis and shocks or by a weak institutional system. Our results are robust and reliable when we use an alternative measure of bank connections, and in the context of controlling the potential endogeneity of global sanction.
本文利用2001-2013年期间66个国家的4032对数据,研究了全球经济制裁(GESs)对全球银行联系的影响。我们将结构重力模型与Felbermayr等人[(2020)]引入的全球制裁数据库的丰富数据库相结合。全球制裁数据库。经济研究,2009(1):1 - 3。我们的实证结果表明GESs和GBLs之间存在负相关。GESs对GBLs的不同影响取决于制裁类型。此外,对于信息不对称程度较高的国家来说,全球制裁的后果更为严重,这些国家要么是由于世界高度不确定性、危机和冲击的发生,要么是由于体制制度薄弱。当我们使用银行联系的另一种衡量标准,并在控制全球制裁潜在内生性的背景下,我们的结果是稳健和可靠的。

Our results are robust and reliable when we use an alternative measure of bank connections, and in the context of controlling the potential endogeneity of global sanction.","PeriodicalId":44015,"journal":{"name":"Global Economy Journal","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91368618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the impact of digital development on the competitiveness indicators of countries and regions. The research methodology was based on the analytic hierarchy process (AHP), a structured technique adapted to solve the nonlinear optimization problem by choosing the most suitable scenario for the public administration of regions’ digital development. The analysis of digital competitiveness across European countries revealed that its development is quite uneven. Within the European Union, both digitalization leaders and outsiders were noted. Modeling three digitalization scenarios for Russia, China, the United States and the countries of Europe allowed defining Scenario 3 (accelerated digitalization) as the best way for managing their development in the context of digital transformation. The significance of the conducted research lies in the fact that it distinguished the digital economy components affecting both digital and overall regions’ competitiveness. The results obtained can be taken advantage of by individuals engaged in the field of economic activity to determine the role of various organizations, strategic levers, and indicators that ensure an effective response to challenges of competition in the regional and global markets.
本研究旨在评估数字化发展对国家和地区竞争力指标的影响。研究方法基于层次分析法(AHP),这是一种结构化技术,适用于通过选择最适合区域公共行政数字化发展的场景来解决非线性优化问题。对欧洲各国数字竞争力的分析表明,其发展相当不平衡。在欧盟内部,数字化领导者和外部人士都受到了关注。通过对俄罗斯、中国、美国和欧洲国家的三种数字化情景进行建模,可以将情景3(加速数字化)定义为在数字化转型背景下管理其发展的最佳方式。本研究的意义在于区分了影响数字区域和整体区域竞争力的数字经济组成部分。所获得的结果可以由从事经济活动领域的个人利用,以确定各种组织,战略杠杆和指标的作用,确保有效应对区域和全球市场竞争的挑战。
