The COVID-19 crisis has revived an old heated debate on whether significant increases in the money supply ultimately lead to higher inflation. Some observers have alluded to the quantity theory of money for that purpose, though in our view, this has sometimes been in a misleading way. Against this background, this paper seeks to clarify several aspects of the quantity theory of money, which are useful to apply it fairly in the current world. First, we review the meaning of the velocity term in the quantity equation. We argue that it has no relevance as a behavioural concept: there is no such thing as a 'desired velocity'. Rather, income velocity should be seen as a variable deriving from a system of parameters and variables related to money demand, as the monetarist approach clearly puts it, with no intrinsic relevance. Second, we clarify the practical relevance that the quantity theory approach can bear in the 21st century. Third, we review the channels and assumptions underlying the asserted quantity theory link between money growth and inflation. In light of our analysis, we conclude that the high money growth rates seen since the pandemic outbreak are unlikely to translate into higher inflation rates.
新冠肺炎危机重新引发了一场由来已久的激烈辩论,即货币供应的大幅增加是否最终会导致更高的通胀。一些观察人士提到了货币数量理论,尽管在我们看来,这有时是一种误导。在此背景下,本文试图澄清货币数量理论的几个方面,这有助于在当今世界公平地应用它。首先,我们回顾一下量方程中速度项的含义。我们认为它与行为概念无关:不存在所谓的“期望速度”。相反,收入速度应该被视为一个变量,从一个与货币需求相关的参数和变量系统中衍生出来,正如货币主义方法明确指出的那样,没有内在的相关性。其次,我们阐明了数量理论方法在21世纪的实际意义。第三,我们回顾了货币增长和通货膨胀之间断言的数量理论联系的渠道和假设。根据我们的分析,我们得出结论,自疫情爆发以来出现的高货币增长率不太可能转化为更高的通货膨胀率。

Technical efficiency of financial inclusion and human development: Insights from the Indian states 金融包容性与人类发展的技术效率:来自印度各州的见解

Financial inclusion programs are used as a major economic development tool in emerging economies. Human development is the major determinant of financial inclusion, creating opportunities for people to better access financial services. The study's major aim is to examine the technical efficiency of financial inclusion of Indian states by Data Envelopment Analysis using human development as input. To achieve this objective, a 3-dimensional Financial Inclusion Index (FII) is constructed for 28 major Indian states from 2010 to 2017. Empirical findings suggest most Indian states are under low and medium financial inclusion, and states with better human development have better FII status. Crucially, technical efficiency results reveal states with better human development perform better in terms of FII. The inconsistency in FII and human development ranks is majorly found in North-eastern and high-income Indian states. Therefore, policymakers in India should focus on promoting human development in low Human Development Index states.

金融普惠计划被用作新兴经济体的主要经济发展工具。人的发展是金融包容性的主要决定因素,为人们更好地获得金融服务创造了机会。该研究的主要目的是通过以人类发展为输入的数据包络分析来检验印度各州金融包容性的技术效率。为了实现这一目标,从2010年到2017年,为印度28个主要邦构建了一个三维金融包容性指数(FII)。实证研究结果表明,印度大多数邦的金融包容性处于中低水平,而人类发展较好的邦具有更好的金融包容性。至关重要的是,技术效率结果显示,人类发展较好的州在FII方面表现更好。FII和人类发展排名的不一致主要发生在印度东北部和高收入州。因此,印度的政策制定者应该把重点放在促进低人类发展指数国家的人类发展上。

This paper surveys the theoretical and empirical literature on the contributions of financial structure to economic growth. Whereas the theoretical literature clarifies the channels through which banks and financial markets may affect resource allocation and hence economic performance, the empirical evidence on the connection between financial structure and economic growth is mixed. There are several methodological problems inherent in the literature, including disparate studies that have been frequently mixed and confused, unsolved econometric issues (endogeneity, heterogeneity and omitted variables) and failure to consider the interaction between banks and capital markets. More rigorous single-country studies are called for.

本文综述了关于金融结构对经济增长贡献的理论和实证文献。尽管理论文献阐明了银行和金融市场可能影响资源配置从而影响经济绩效的渠道,但关于金融结构与经济增长之间联系的实证证据却喜忧参半。文献中存在一些固有的方法论问题,包括经常混淆和混淆的不同研究、未解决的计量经济学问题(内生性、异质性和遗漏变量)以及未能考虑银行和资本市场之间的相互作用。需要进行更严格的单一国家研究。

Community banks versus non-community banks: Post the Great Recession 社区银行与非社区银行:大衰退后

Community banks (CBs), despite holding a fairly small share of US banking assets, provide vital financial services to key segments of the economy and fill a void untapped by larger non-community banks (Non-CBs). They face challenges brought on by a fast-changing banking landscape, evolving technology, and ever-increasing regulatory burden. To remain competitive and to gain scale-related efficiencies, CBs have been seeking mergers even as greater institutional size causes a departure from the classical relationship-based business model. This study examines performance of US CBs and Non-CBs post the Great Recession to reveal how size of these institutions may affect their business operations. Empirical findings show that CBs, compared with their larger counterparts, tend to maintain higher levels of liquidity and lower levels of capital, and demonstrate a greater dependence on core deposits, confirming that CBs focus on deposit taking and soft information-based lending strategies. Furthermore, this study suggests that CBs should not be considered a homogenous group operating under a singular business model and cautions that regulatory dialectics aimed at the banking industry should not employ a one-size-fits-all approach.

尽管社区银行在美国银行资产中所占份额相当小,但它为经济的关键部门提供了至关重要的金融服务,并填补了大型非社区银行尚未开发的空白。他们面临着快速变化的银行业格局、不断发展的技术和不断增加的监管负担带来的挑战。为了保持竞争力并获得与规模相关的效率,即使更大的机构规模导致偏离传统的基于关系的商业模式,CB也一直在寻求合并。这项研究考察了大衰退后美国CBs和非CBs的表现,以揭示这些机构的规模如何影响其业务运营。实证结果表明,与规模较大的同业相比,CB往往保持较高的流动性水平和较低的资本水平,并表现出对核心存款的更大依赖性,这证实了CB专注于接受存款和基于软信息的贷款策略。此外,这项研究表明,不应将CB视为在单一商业模式下运营的同质集团,并警告针对银行业的监管辩证法不应采用一刀切的方法。

Exploring the dependencies among main cryptocurrency log-returns: A hidden Markov model 探索主要加密货币日志回报之间的相关性:一个隐马尔可夫模型

A hidden Markov model is proposed for the analysis of time-series of daily log-returns of the last 4 years of Bitcoin, Ethereum, Ripple, Litecoin, and Bitcoin Cash. These log-returns are assumed to have a multivariate Gaussian distribution conditionally on a latent Markov process having a finite number of regimes or states. The hidden regimes represent different market phases identified through distinct vectors of expected values and variance–covariance matrices of the log-returns, so that they also differ in terms of volatility. Maximum-likelihood estimation of the model parameters is carried out by the expectation–maximisation algorithm, and regimes are singularly predicted for every time occasion according to the maximum-a-posteriori rule. Results show three positive and three negative phases of the market. In the most recent period, an increasing tendency towards positive regimes is also predicted. A rather heterogeneous correlation structure is estimated, and evidence of structural medium term trend in the correlation of Bitcoin with the other cryptocurrencies is detected.

提出了一个隐马尔可夫模型,用于分析比特币、以太坊、Ripple、莱特币和比特币现金最近4年的每日日志回报时间序列。假设这些对数回归在具有有限数量的状态或状态的潜在马尔可夫过程上有条件地具有多变量高斯分布。隐藏制度代表了通过预期值的不同向量和对数收益的方差-协方差矩阵识别的不同市场阶段,因此它们在波动性方面也有所不同。模型参数的最大似然估计通过期望-最大化算法进行,并且根据最大后验规则对每个时间场合的状态进行奇异预测。结果显示了市场的三个积极和三个消极阶段。在最近的一段时间里,还预测了积极制度的增长趋势。估计了一个相当异质的相关性结构,并检测到比特币与其他加密货币相关性的结构性中期趋势的证据。
