Stock Returns, Trading Volumes and Market Volatility: A Study on the Indian Stock Market 股票收益、交易量与市场波动:对印度股票市场的研究
P. K. Naik, Tapas Kumar Sethy
This paper aims at investigating the effect of stock returns on trading volume and the trading volume on volatility. To accomplish the study objective, daily data from 1 April 2014 to 30 June 2020 are used. The GLS model is employed to investigate the contemporaneous relationship between the stock returns and trading volume. The EGARCH (1, 1) model is used to explore the volume–volatility relationships, and the causal relationship of stock returns–trading volumes–volatility is attained through the Granger causality test. The study finds that the effect of stock returns on trading volume is asymmetric. It indicates that the negative price changes have a less considerable impact on trading volume than the non-negative price changes. The study also supports the mixture of the distribution hypothesis that postulated the volume–volatility relationship to be positive. The volatility persistence level remains high, even after the conditional volatility model incorporates trading volumes as an exogenous variable. Further, the analysis also reveals that stock return causes trading volume and not vice versa; however, trading volumes cause return volatility. JEL Codes: G10, G12, C22
本文旨在研究股票收益对交易量的影响以及交易量对波动率的影响。为了实现研究目标,使用了2014年4月1日至2020年6月30日的日常数据。采用GLS模型研究股票收益与交易量的同期关系。采用EGARCH(1,1)模型探讨成交量与波动率之间的关系,通过Granger因果检验得到股票收益-成交量-波动率之间的因果关系。研究发现,股票收益对交易量的影响是不对称的。这表明负价格变化对交易量的影响小于非负价格变化。该研究还支持混合分布假设,即假设体积-波动率关系为正。即使在条件波动率模型将交易量作为外生变量后,波动率持续水平仍然很高。进一步分析还发现,股票收益导致交易量,而不是相反;然而,交易量会导致回报率波动。JEL代码:G10, G12, C22

Revealed Comparative Advantage in Services Exports: How Is India Different from China? 服务出口比较优势显现:印度与中国有何不同?
Purna Banerjee, Rajmal
In recent years, India has become one of the select few emerging economies to feature in the list of the world’s top services exporters. However, given similarities in demography, resource endowments and comparable shares in world services exports, India faces potential competition from China in this sector. Using a theoretically founded, regression-based measure of revealed comparative advantage, we contrast India’s revealed comparative advantage vis-à-vis China in disaggregated services sectors between 2005 and 2018. India, we find, has a comparative advantage in sectors, such as ‘telecommunications, computer, and information services’ and ‘other business services’. However, China’s advantage lies in ‘manufacturing services’ and ‘transport’. Notably, the sectors of India’s comparative advantage are also the sunrise sectors within services, displaying high growth rates and an increasing share in world services trade. A related measure—the trade elasticity index—reveals that, due to sectoral differences in comparative advantage, China does not pose a major threat to India in most of the latter’s major export destinations. Our finding implies that even if China were to enter free trade agreements with India’s major services export partners, the trade diversion losses for India would be small. JEL Codes: F11, F14
近年来,印度已成为少数几个入选世界顶级服务出口国名单的新兴经济体之一。然而,考虑到人口结构、资源禀赋和在世界服务出口中的可比份额的相似性,印度在这一领域面临着来自中国的潜在竞争。使用一种基于理论的、基于回归的揭示比较优势测度,我们对比了2005年至2018年间印度在分类服务部门相对于中国的揭示比较优点。我们发现,印度在“电信、计算机和信息服务”以及“其他商业服务”等领域具有相对优势。然而,中国的优势在于“制造业服务业”和“运输业”。值得注意的是,印度的比较优势部门也是服务业中的朝阳部门,表现出高增长率,在世界服务贸易中所占份额不断增加。一项相关指标——贸易弹性指数——显示,由于比较优势的部门差异,中国在印度的大多数主要出口目的地不会对印度构成重大威胁。我们的研究结果表明,即使中国与印度的主要服务出口伙伴签订自由贸易协定,印度的贸易转移损失也很小。JEL代码:F11、F14

Bank Financial Performance and its Linkage with Capital: A Dynamic Panel Data Analysis of Public Sector Banks in India 银行财务绩效及其与资本的联系——印度公共部门银行的动态面板数据分析
Arindam Bandyopadhyay
This article empirically investigates the linkage of capital infusion in the Public Sector Banks (PSBs) in India with the capital adequacy, asset quality, profitability, operational efficiency and the market position of the banks. Utilising a balanced panel data of total 21 PSBs over 9 years (2009 to 2017), we analyse the key determinants of the Indian PSBs’ profitability, net interest margin (NIM), solvency and market efficiency. The study applies a two-step dynamic panel generalised methods of moments. We find empirical evidence that the Capital Infusion programme of the Government during 2008–2009 to 2016–2017 has significant impact on the performance of PSBs in India. We have observed that with frequent infusion of capital by the government, banks were able to meet the regulatory Basel II/III capital adequacy requirements and it has positive influence on their market capitalisation as well as NIM. However, capital infusion has an insignificant impact on improving return on assets (ROA) of banks. Our study suggests that a higher common equity tier 1 capital ratio leads to better market reputation and solvency position of the banks. The results of the study provides insight for bank management, regulators and policymakers for improving bank performance and better utilisation of scarce capital and public money.

本文实证研究了印度公共部门银行(PSBs)的资本注入与银行资本充足率、资产质量、盈利能力、运营效率和市场地位的联系。利用9年(2009年至2017年)共21家储蓄银行的平衡面板数据,我们分析了印度储蓄银行盈利能力、净息差(NIM)、偿付能力和市场效率的关键决定因素。本研究采用两步动态面板广义矩法。我们发现实证证据表明,政府在2008-2009年至2016-2017年期间的资本注入计划对印度邮政储蓄银行的绩效产生了重大影响。我们观察到,在政府频繁注资的情况下,银行能够满足巴塞尔协议II/III资本充足率的监管要求,这对银行的市值和NIM都有积极的影响。而资本注入对提高银行资产收益率的影响不显著。我们的研究表明,较高的普通股一级资本比率会导致银行更好的市场声誉和偿付能力状况。研究结果为银行管理层、监管机构和政策制定者提供了改善银行绩效和更好地利用稀缺资本和公共资金的见解。JEL代码:G21, G32, G34

Public Finance Management in India in the Time of COVID-19 Pandemic 新冠肺炎大流行时期的印度公共财政管理
S. Mukherjee, Shivani Badola
Due to the COVID-19 pandemic, public finance management (PFM) in the FY 2020–2021 and 2021–2022 have become extremely challenging. The economic contraction has created pressures on PFM in India in terms of lower revenue mobilisation and higher expenditure needs. Both the union and state governments are facing dual problem of arresting economic contraction and managing public finance with limited resources. The present article analyses public finance management of the union as well as 16 major Indian states during the time of COVID-19 pandemic. For comparison, we have also analysed pre-COVID public finance monthly data of state governments. The shock to PFM came from both the revenue as well as expenditure side. Apart from aggregate analysis of state finances of 16 major states, we present state-wise analysis to highlight measures adopted by states to deal with the unprecedented fiscal crisis.

Supramolecular nanotubes produced by self-assembly of organic molecules can have unique structural features such as a one-dimensional morphology with no branching, distinguishable inner and outer surfaces and membrane walls, or a structure that is hollow and has a high aspect ratio. Incorporation of functional groups that respond to external chemical or physical stimuli into the constituent organic molecules of supramolecular nanotubes allows us to drastically change the structure of the nanotubes by applying such stimuli. This ability affords an array of controllable approaches for the encapsulation, storage, and release of guest compounds, which is expected to be useful in the fields of physics, chemistry, biology, and medicine. In this article, I review the supramolecular nanotubes developed by our group that exhibit morphological transformations in response to pH, chemical reaction, light, temperature, or moisture.

Does Regulation Impact the Initial Returns of Initial Public Offerings? Evidence from Indian Capital Market 监管是否影响首次公开募股的初始回报?来自印度资本市场的证据
A. Singh, Tripti Goel
Regulations are put in place in the capital markets to protect the interests of investors while promoting companies to actively participate in the capital markets. This multidisciplinary study concentrates on analysing the impact of one such regulation, based on entry norms, on the initial returns of book-built IPOs in the presence of firm-related and issue-related control variables, thereby facilitating decision-making to issuers and investors. Using various parametric and non-parametric tests on 259 IPOs issued on Indian Stock Exchanges during financial year 2009–2010 to 2019–2020, it can be concluded that Indian IPOs are underpriced on an average, irrespective of the entry norm followed. Further, firms entering through either of the entry routes, that is, profitability route or Qualified Institutional Buyer Route have significant differences in age, listing delay, type of sale, rank of lead managers and industry. Entry norm is established to have a negative yet insignificant role in determining the initial returns, while oversubscription is the only variable with a positive and significant impact on the initial returns of the issue.

资本市场制定了相关规定,以保护投资者的利益,同时促进公司积极参与资本市场。这项多学科研究的重点是分析在存在与公司相关和与发行相关的控制变量的情况下,基于进入规范的一项此类监管对账面首次公开募股初始回报的影响,从而为发行人和投资者的决策提供便利。通过对2009-2010财年至2019-2020财年在印度证券交易所发行的259只IPO进行各种参数和非参数测试,可以得出结论,无论遵循何种进入规范,印度IPO的平均定价都偏低。此外,通过盈利途径或合格机构买家途径进入的公司在年龄、上市延迟、销售类型、首席经理级别和行业方面存在显著差异。进入规范在确定初始回报方面起着消极但不重要的作用,而超额认购是唯一对发行初始回报产生积极和重大影响的变量。JEL代码:G10、G14、G18、G23、K22

Differences in Efficiency in the Formal–Informal Dichotomy—A Study of Indian Firms 正式-非正式二分法下的效率差异——对印度企业的研究
R. Kumari
The unorganised manufacturing industries play a vital role in the process of industrial development of the Indian economy. Informal firms are relatively less productive than formal firms, because a majority of the firms are technically inefficient, producing far below the actual attainable level of production. This article examines differences in efficiency and output between formal and informal production firms across India’s manufacturing industries. The key novelty in this article is in studying both the formal and informal sectors simultaneously by applying the technique of Oaxaca–Blinder decomposition to determine efficiency differences across the sectors. The results suggest that capital is a positive and the most significant determinant of the output of efficient industries. Output gaps can be explained by coefficient, endowment and interaction aspects of capital and capital productivity, while efficiency differences are explained by coefficient and interaction characteristics of emoluments and capital productivity. The results of density plots show that informal firms are no longer functioning as a pool of surplus labour in the context of Indian manufacturing industries during these years. The results dispel the notion that the informal sector is a poor performer in terms of total output compared to the formal sector. Also, capital and capital productivity are less in informal manufacturing industries than in the formal sector. JEL Codes: E26, J46, O14, O17
无组织的制造业在印度经济的工业发展过程中起着至关重要的作用。非正式企业的生产率相对低于正式企业,因为大多数非正式企业在技术上效率低下,生产远远低于实际可达到的生产水平。本文考察了印度制造业正规生产企业和非正规生产企业在效率和产出方面的差异。本文的关键新颖之处在于,通过应用瓦哈卡-布林德分解技术,同时研究了正式部门和非正式部门,以确定部门之间的效率差异。研究结果表明,资本对高效产业的产出具有最显著的正向决定作用。产出差距可以用资本和资本生产率的系数、禀赋和相互作用来解释,而效率差异可以用薪酬和资本生产率的系数和相互作用特征来解释。密度图的结果表明,这些年来,在印度制造业的背景下,非正规企业不再发挥剩余劳动力池的作用。研究结果驳斥了非正规部门在总产出方面不如正规部门的观点。此外,非正规制造业的资本和资本生产率低于正规部门。JEL代码:E26, J46, O14, O17

Revisit Financial Integration in Asia: New Time-Series Evidence from Stock Markets 重新审视亚洲金融一体化:来自股市的新时间序列证据
T. Saji
This research reinvestigates stock market linkages in Asian region by employing Johansen cointegration and vector error correction model (VECM) based causality tests. The stock price indexes of Japan, Singapore, South Korea, India and China are used, with monthly data over 1999:09–2019:10. The empirical results find weak price convergence among Asian markets, hence are almost segmented by national borders. The asymmetrical stock price relations in Asia have important implications for the pricing efficiency of national markets and suggest several opportunities for global investors to optimise returns through portfolio diversifications across leading stock markets of the region. JEL Codes: C58; G11; G15
本研究采用基于Johansen协整和向量误差修正模型(VECM)的因果关系检验,重新探讨亚洲地区股市的关联性。使用日本、新加坡、韩国、印度和中国的股票价格指数,每月数据为1999:09-2019:10。实证结果发现,亚洲市场的价格趋同程度较弱,因此几乎被国界分割。亚洲不对称的股票价格关系对国内市场的定价效率具有重要影响,并为全球投资者提供了若干机会,通过在该地区主要股票市场进行投资组合多元化来优化回报。JEL代码:C58;为G11;G15

Sources of Instability in Nigeria’s Manufacturing Performance: 1981–2018 尼日利亚制造业表现不稳定的根源:1981年至2018年
Mike A. Onodje, P. Onodje
The article investigates factors that may be responsible for observed instability in Nigeria’s manufacturing sector performance. Based on growing concerns regarding early deindustrialisation observed for many developing countries, the study examines how a menu of fiscal and monetary policies can be applied to revitalise the Nigerian manufacturing sector. Consequently, we construct an index of manufacturing sector instability and examine how it responds to a mixture of fiscal and monetary policy variables. We use annual time series data from 1981–2018 and apply the ARDL bounds test technique. Our findings show that budget deficits induce instability in the performance of the Nigerian manufacturing sector, while government infrastructural investments stabilise it. The monetary policy instruments were found to have inconsistent short-run and long-run influences but mostly conform with theory. JEL Codes: F63, L20, L25, L60, O10, O14
这篇文章调查了可能导致尼日利亚制造业表现不稳定的因素。基于对许多发展中国家早期去工业化的日益担忧,该研究考察了如何应用一系列财政和货币政策来振兴尼日利亚制造业。因此,我们构建了一个制造业不稳定指数,并考察了它对财政和货币政策变量的反应。我们使用1981年至2018年的年度时间序列数据,并应用ARDL边界测试技术。我们的研究结果表明,预算赤字会导致尼日利亚制造业表现的不稳定,而政府基础设施投资会稳定制造业。货币政策工具的短期和长期影响不一致,但大多符合理论。JEL代码:F63、L20、L25、L60、O10、O14
