In this article, network analysis has been employed to study the dynamic evolution of the cryptocurrency market from 1 January 2020 to 1 January 2024. This approach facilitates an in-depth exploration of the market’s response to several major events during this period, including the coronavirus disease of 2019 (COVID-19) pandemic and the bankruptcy of FTX, one of the largest cryptocurrency exchanges. The study focuses on analysing key network characteristics of the cryptocurrency market, namely: (a) degree centrality, (b) betweenness centrality, (c) clustering coefficient and (d) average path length. Additionally, we explore the co-movements within the market, categorising cryptocurrencies into functional groups for a comparative analysis. This approach enables us to examine shifts in the cryptocurrency network topology, providing insights into how different groups of cryptocurrencies interact with and influence each other. Through this network analysis, we aim to shed light on the intricate interrelationships among cryptocurrencies. The findings of this study are intended to provide investors with valuable insights, potentially guiding the development of more informed and strategic diversification strategies in the dynamic and evolving landscape of the cryptocurrency market.JEL Codes: G11, G12, D85

Green transition by reducing CO2 emissions and curtailing the exploitation of natural resources while increasing renewable energy use and generation is one of the most important targets in sustainable development. This study investigated the impacts of women’s empowerment in politics on the green transition in developing countries. We applied a fixed-effects model to the panel data for 131 developing countries from 2000 to 2019. Our findings indicated that higher levels of participation by women in politics are likely to reduce CO2 emissions and reliance on natural resources. However, there was no statistically significant effect of women’s political empowerment on renewable energy consumption. Women’s political participation enhanced the transition towards sustainable energy sources such as geothermal and wind energy. We also found that the effects of women’s political participation on CO2 emissions were greater in countries with better political stability, government effectiveness, regulatory quality, rule of law, control of corruption, and voice and accountability. This study contributes to the growing literature in feminism and environmentalism on the achievement of sustainable development. JEL Codes: J16, O13, P48
通过减少二氧化碳排放和减少自然资源的开采,同时增加可再生能源的使用和生产,实现绿色转型是可持续发展的最重要目标之一。本研究调查了妇女政治赋权对发展中国家绿色转型的影响。我们对 131 个发展中国家 2000 年至 2019 年的面板数据采用了固定效应模型。我们的研究结果表明,妇女参政水平越高,越有可能减少二氧化碳排放和对自然资源的依赖。然而,妇女政治赋权对可再生能源消费没有显著的统计影响。妇女参政促进了向地热和风能等可持续能源的过渡。我们还发现,在政治稳定性、政府效率、监管质量、法治、腐败控制以及发言权和问责制较好的国家,妇女参政对二氧化碳排放的影响更大。本研究为女性主义和环保主义在实现可持续发展方面日益增多的文献做出了贡献。JEL Codes:J16, O13, P48

Cryptocurrency has recently emerged as a financial asset among policymakers, investors and academics as a new alternative asset in the financial landscape. This research intends to empirically evaluate the safe haven, diversification and hedging potentials of digital currencies against the Indian equity market during different time frames. Four cryptocurrencies (Bitcoin, Ethereum, Binance Coin and Ripple) and Nifty 50 index data have been collected on a daily basis, from 26 July 2017 to 31 August 2023, for this purpose. Using wavelet-based methods, the study has discovered higher volatility in Nifty 50 and cryptocurrency prices during the crisis and stronger co-movement between pairs of equities and cryptocurrencies. Furthermore, the study finds that, under normal economic conditions, cryptocurrency can hedge the Indian stock market over short-term, medium-term and long-term investment horizons. However, investing in cryptocurrencies in the Indian stock portfolio for the short term does not give any safe haven or diversification advantages during times of economic crisis. Finally, we anticipate that the findings of our study will provide valuable insights into the potential usage of cryptocurrencies in the Indian stock market, both in stable and turbulent economic conditions.

最近,加密货币作为一种新的替代资产出现在政策制定者、投资者和学术界的视野中。本研究旨在对不同时间段内数字货币相对于印度股票市场的避风港、多样化和对冲潜力进行实证评估。为此收集了四种加密货币(比特币、以太坊、Binance Coin 和瑞波币)和 Nifty 50 指数的每日数据,时间从 2017 年 7 月 26 日至 2023 年 8 月 31 日。研究采用基于小波的方法,发现危机期间 Nifty 50 指数和加密货币价格的波动性更高,股票和加密货币对之间的共动性更强。此外,研究还发现,在正常经济条件下,加密货币可以在短期、中期和长期投资范围内对冲印度股市。然而,在印度股票投资组合中短期投资加密货币并不能在经济危机时期带来任何避风港或多样化优势。最后,我们预计,我们的研究结果将为印度股票市场在稳定和动荡的经济条件下使用加密货币的潜力提供有价值的见解。JEL Codes:G01, G41, N2, P34

People tend to believe that more information will improve the accuracy of predicting outcomes in highly uncertain situations. This behaviour, known as ‘illusion of knowledge,’ is related to overconfidence in multiple areas of study, and attracts scientific attention. The aim of this research is to determine the academic evolution of the illusion of knowledge within the financial field. For this purpose, two different methodologies have been used to generate a more solid contribution. The first part is based on the ReSiste-CSH bibliographic framework raised for the study of social sciences, and the second part uses the Bibliometrix software to measure the performance of the subject over time. The Web of Science academic database was used as a reference source for the period 1987–2021, resulting in a sample of 1,202 papers in highly impactful academic journals. The results show a positive evolution over time in the number of publications, as well as a geographical concentration in journals of the Q1 category from the United States and the United Kingdom, together with a close relationship with areas of study such as psychology, business and economics, among others. JEL Code: G41
人们倾向于相信,在高度不确定的情况下,更多的信息会提高预测结果的准确性。这种行为被称为“知识幻觉”,与在多个研究领域的过度自信有关,并引起了科学界的关注。本研究的目的是确定知识幻觉在金融领域的学术演变。为此目的,使用了两种不同的方法来产生更可靠的贡献。第一部分是基于为社会科学研究而提出的resist - csh书目框架,第二部分使用Bibliometrix软件来衡量学科的长期表现。Web of Science学术数据库被用作1987-2021年期间的参考来源,产生了1202篇发表在极具影响力的学术期刊上的论文样本。结果显示,随着时间的推移,出版物数量呈积极发展趋势,美国和英国Q1类期刊的地理分布集中,以及与心理学、商业和经济学等研究领域的密切关系。JEL代码:G41

At the moment, the first phase of the military confrontation between Russia and Ukraine, which began in February 2022, is reaching its logical end: A certain front line has already been established and the economic state in which the countries are is becoming clearer. That is why the evaluation and forecasting of the military, economic and demographic impact of the war on other countries become relevant. This work examines what losses Russia received due to its actions. In the article, the authors examine the issue of the impact of the war in Ukraine on the Russian economy, as well as a retrospective forecast of the impact of Russia’s military operations on its national economy. Attention is focused on military and demographic aspects, as well as on the results of the impact of various types of sanctions. The main method that was used in the work can be considered modelling; however, in addition to it, analysis, historical method, graphic and others were also used. The practical results of the analysis showed that the government of the Russian Federation announced the transition to a command mobilisation economy, and today its first consequences are already visible in the form of rising prices and devaluation of the national currency. In addition, it was shown that despite the large number of sanctions imposed on Russia, the country has not yet felt the full consequences. The issue of how the defence economy of the Russian Federation is developing, how the military budget of Russia has changed over the past 11 years, and how the war in Ukraine affected the demographic situation has been examined. In the section on the impact of the war on the economy of the Russian Federation, it is shown that modernised production and industries will suffer the most from such actions, which will lead to a powerful technological lag. The article brings new knowledge for understanding the current functioning of the Russian economy and in the near future, as well as for making assessments of the possible future course of the war.

目前,始于2022年2月的俄乌军事对抗的第一阶段已经到了逻辑上的终点:一条特定的战线已经确立,两国的经济状态也越来越清晰。这就是为什么评估和预测战争对其他国家的军事、经济和人口影响变得至关重要。这项工作考察了俄罗斯因其行动而遭受的损失。在文章中,作者考察了乌克兰战争对俄罗斯经济的影响问题,并对俄罗斯军事行动对其国民经济的影响进行了回顾性预测。人们的注意力集中在军事和人口方面,以及各种制裁的影响所产生的结果。在工作中使用的主要方法可以考虑建模;但除此之外,还运用了分析法、历史法、图解法等。分析的实际结果表明,俄罗斯联邦政府宣布向指挥动员经济过渡,今天其第一个后果已经以价格上涨和本国货币贬值的形式出现。此外,有迹象表明,尽管对俄罗斯实施了大量制裁,但该国尚未感受到全部后果。对俄罗斯联邦国防经济如何发展、俄罗斯军事预算在过去11年中如何变化以及乌克兰战争如何影响人口状况等问题进行了研究。在关于战争对俄罗斯联邦经济的影响的一节中,表明现代化的生产和工业将受到这种行动的最大影响,这将导致强大的技术滞后。这篇文章为理解当前俄罗斯经济的运作和在不久的将来带来了新的知识,也为评估未来战争的可能进程提供了新的知识。耶利米:h56, n4, j11, r11

An Impact Analysis of Remittance Inflows on Reducing Income-based Poverty in South Asia 汇款流入对减少南亚收入型贫困的影响分析

The purpose of this paper is to empirically examine the role of remittance inflow in reducing poverty in the South Asian region. A time-series dataset of the South Asian region for the period 1980–2021 is being considered for this study, and the autoregressive distributed lags model has been applied to examine the short- and long-run relationship between remittance inflows along with control variables, including inflation, trade openness and economic growth on poverty reduction. The results indicated that remittances have a substantial effect on poverty in both the short and long run. While inflation appeared to be a barrier to poverty reduction in the long term. Lastly, trade openness was also found to negatively affect poverty in the long run. It is the first inference in the context of South Asia that has captured income-based poverty in the form of household consumption expenditure. The study suggests that economic policymakers should devise the policy in such a manner that remittance inflows can be used for investment rather than only for consumption. Furthermore, inflation should be kept under control in the long run, and trade policies should be designed in such a way that they provide leverage to small-scale entrepreneurs, thereby reducing poverty in the long run.

本文的目的是实证检验汇款流入在南亚地区减少贫困中的作用。本研究正在考虑南亚地区1980-2021年期间的时间序列数据集,并应用自回归分布滞后模型来检验汇款流入与控制变量(包括通货膨胀、贸易开放和经济增长)之间的短期和长期关系。研究结果表明,从短期和长期来看,汇款对贫困都有重大影响。从长远来看,通货膨胀似乎是减少贫穷的障碍。最后,从长远来看,贸易开放也会对贫困产生负面影响。这是在南亚范围内第一个以家庭消费支出的形式反映以收入为基础的贫困的推论。这项研究表明,经济政策制定者应该以这样一种方式设计政策,即汇款流入可以用于投资,而不仅仅是用于消费。此外,从长远来看,通货膨胀应得到控制,贸易政策的设计应使它们能够向小规模企业家提供杠杆作用,从而从长远来看减少贫穷。JEL代码:F24, F62, F63, P46

Is Female Genital Circumcision a Driver of Income Inequality in Sub-Saharan Africa? Evidence from Nigeria 女性生殖器割礼是撒哈拉以南非洲收入不平等的驱动因素吗?来自尼日利亚的证据

This study considers the effects of female genital circumcision (FGC) on household income inequality in Nigeria. To the extent that FGC has adverse health consequences, it can lower female labour productivity and earnings relative to males. Theoretically, we motivate our inquiry within a simple game-theoretic household norm bargaining framework in which there are several possible equilibria based on the decisions of representative males to require FGC, and representative females accepting, or not. We link regional data on Nigeria from the Afrobarometer survey to existing regional FGC surveillance data in Nigeria to estimate with Ordinal Logit specifications, the effect of regional FGC rates on a household’s position in the income distribution. Our parameter estimates reveal that as the ratio of daughter to mother genital circumcision increases in a region, the odds of a household being in the lower income decile increases. The FGC effects are consistent with a political economy of gender bargaining about FGC choices in which males have more bargaining power in governing/managing the household relative to females. Our results suggest that any policy intervention that eradicates FGC, including interventions that affect a political economy of bargaining that at least equalises bargaining power between males and females, could reduce household income inequality in Sub-Saharan Africa.

本研究考虑了尼日利亚女性生殖器割礼(FGC)对家庭收入不平等的影响。就女性生殖器切割对健康产生不利影响而言,它可能降低女性的劳动生产率和相对于男性的收入。从理论上讲,我们在一个简单的博弈论家庭规范谈判框架中激发我们的研究,在这个框架中,有几个可能的平衡是基于代表性男性要求FGC的决定,以及代表性女性接受或不接受FGC的决定。我们将来自非洲晴雨表调查的尼日利亚区域数据与尼日利亚现有的区域FGC监测数据联系起来,用序数Logit规范估计区域FGC率对家庭在收入分配中的地位的影响。我们的参数估计表明,随着一个地区女儿与母亲生殖器割礼比例的增加,家庭处于较低收入十分之一的几率也会增加。女性生殖器切割效应与女性生殖器切割选择的性别讨价还价的政治经济学是一致的,在这种政治经济学中,男性在治理/管理家庭方面比女性拥有更多的讨价还价能力。我们的研究结果表明,任何根除FGC的政策干预,包括影响议价政治经济学的干预,至少可以使男性和女性之间的议价能力平等,都可以减少撒哈拉以南非洲地区的家庭收入不平等。耶利米书:14、18、16、15、13

To the extent that FGC has adverse health consequences, it can lower female labour productivity and earnings relative to males. Theoretically, we motivate our inquiry within a simple game-theoretic household norm bargaining framework in which there are several possible equilibria based on the decisions of representative males to require FGC, and representative females accepting, or not. We link regional data on Nigeria from the Afrobarometer survey to existing regional FGC surveillance data in Nigeria to estimate with Ordinal Logit specifications, the effect of regional FGC rates on a household’s position in the income distribution. Our parameter estimates reveal that as the ratio of daughter to mother genital circumcision increases in a region, the odds of a household being in the lower income decile increases. The FGC effects are consistent with a political economy of gender bargaining about FGC choices in which males have more bargaining power in governing/managing the household relative to females. Our results suggest that any policy intervention that eradicates FGC, including interventions that affect a political economy of bargaining that at least equalises bargaining power between males and females, could reduce household income inequality in Sub-Saharan Africa.

Promotional Effects of Recorded Music and Superstars on Concert Financial Outcomes 录制音乐和超级明星对演唱会财务结果的促进作用
Q3 Economics, Econometrics and Finance Pub Date : 2023-09-28 DOI: 10.1177/02601079231168750
Eric Hogue
Using a comprehensive data set of hand-collected observations of top touring performing artists, I examine the complementary relationship between recorded music and concert financial outcomes. I find that music streaming derives substantive financial benefit to the top 100 touring artists as a means to promote their live performances. Using empirical estimates from a panel model with artist fixed effects, an artist can derive an incremental $46K to $49K per show when achieving a 20% increase in music streaming. Additionally, using a 2SLS model with artist fixed effects to account for potential endogenous promotional effects, I identify top performers (or ‘superstars’) who derive significant additional concert revenue because of their back catalogue of hit songs. These top performers earn an incremental $15K per show for every week they have a song from their catalogue in the Billboard Top 20. These findings indicate that artists can use their legacy to build lifelong earnings from their music and performances. JEL Classifications: D12, D22, L82, Z10
通过对顶级巡演表演艺术家手工收集的综合观察数据集,我研究了录制音乐和演唱会财务结果之间的互补关系。我发现音乐流媒体为前100名巡演艺术家带来了实质性的经济利益,作为推广他们现场演出的一种手段。使用具有艺术家固定效果的面板模型的经验估计,当音乐流媒体增加20%时,艺术家每场演出可以获得4.6万至4.9万美元的增量收入。此外,我使用带有艺术家固定效应的2SLS模型来解释潜在的内生推广效应,我确定了顶级表演者(或“超级明星”),他们因为热门歌曲的后台目录而获得了显著的额外演唱会收入。这些顶级表演者每一场演出就能获得1.5万美元的增量收入,每周他们的歌曲目录中就有一首歌进入公告牌前20名。这些发现表明,艺术家可以利用他们的遗产从他们的音乐和表演中获得终身收入。JEL分类:D12, D22, L82, Z10

Extending the Capabilities Conception of the Individual in Economics: Relationality and Responsibility 经济学中个人能力概念的拓展:关系与责任
IF 0.6 Q3 Economics, Econometrics and Finance Pub Date : 2023-08-31 DOI: 10.1177/02601079231179372

This article extends the capabilities conception of individuals developed by Davis, understanding capabilities as relationships. I first introduced the main concepts that are useful for this extension, namely those of agency and capabilities. Then, I showed that agency refers to a rational and responsible exercise of capabilities through Ricoeurs analysis of Sens earlier works. I successively developed the concept of capabilities as relationships through the distinction between intrapersonal and interpersonal relationships: in this framework, self-scrutiny and relationality, respectively, become the leading capabilities of these two relationships. From this extension of the capabilities conception of the individual, two concepts arise with a certain strength, namely those of responsibility and relationality. This extension of the capabilities conception of the individual in economics also in terms of interpersonal relationships emphasises that this social conception of the individual is characterised by relationality. Thanks to responsibility and relationality, the capabilities conception of the individual might be applied in fields such as contemporary civil economy and ecological economics.

本文扩展了Davis提出的个人能力概念,将能力理解为关系。我首先介绍了对这个扩展有用的主要概念,即代理和能力。然后,我通过里科斯对他早期作品的分析表明,代理是指理性的、负责任的能力行使。我先后通过对人际关系和人际关系的区分,发展了能力即关系的概念:在这个框架下,自我审视和关系性分别成为这两种关系的主导能力。从个人能力概念的这种延伸中,出现了两个具有一定力量的概念,即责任和关系。经济学中个人能力概念的延伸,在人际关系方面也强调了个人的社会概念的特点是关系。由于责任和关系,个体的能力概念可以应用于当代公民经济学和生态经济学等领域。JEL分类:B31, B410, B59, Z13

Structural and Exchange Occupational Mobility in India, 1994–2018: A Log-Linear Model- Based Analysis 1994-2018年印度结构性与交换性职业流动:基于对数线性模型的分析
IF 0.6 Q3 Economics, Econometrics and Finance Pub Date : 2023-08-29 DOI: 10.1177/02601079231176390
Nawazuddin Ahmed, D. K. Nauriyal
This article examines intergenerational structural and exchange occupational mobility in India. Using data from India’s multiple National Sample Surveys’ employment and Periodic Labour Force Survey rounds, the study investigates co-resident father-son relationships from 1993–1994 to 2017–2018. It employs a log-linear model with a quasi-symmetry fit—also called an SHD model—to estimate the structural and exchange components of occupational mobility. This work reveals that intergenerational mobility owes considerably to economic structural shifts and that exchange mobility for the larger study period from 1993–1994 to 2011–2012 remains low. However, it also suggests that there has been an increase in exchange occupational mobility in recent survey year (2017–2018). JEL Classification: J62, J24
本文考察了印度的代际结构和交换职业流动。该研究使用了印度多次全国抽样调查的就业和定期劳动力调查轮次的数据,调查了1993-1994年至2017-2018年期间共同居住的父子关系。它采用了一个准对称拟合的对数线性模型——也称为SHD模型——来估计职业流动的结构和交换成分。这项研究表明,代际流动性在很大程度上归因于经济结构的转变,从1993-1994年到2011-2012年的更大研究期间,交换流动性仍然很低。然而,它也表明,在最近的调查年度(2017-2018),交换职业流动性有所增加。JEL分类:J62、J24
