Available in PDF, EPUB and Kindle. Book excerpt: Positive relationship between trade volume and return volatility is a well-known empirical verified regularity in the financial research. Several studies examined what causes to volume-volatility to evolve and numerous theoretical explanations have been developed to predict/explore this relationship (see Karpoff (1987) and Board et al (1990) for a number of reasons why price-volume affiliation is positive). However, the recent literature provides evidence of revisiting the volume-volatility relationship as volatility and transaction counts relationship. So far no study examines the role of transactions frequency over and above volume in explaining the volatility; hence, the present study attempts to uncover the relevance of transaction counts for Indian stock market. Specifically, the study considers component stocks of Indian barometer indices, NSE Nifty and Nifty Junior, for the period 2005. In addition, study measures volatility by five minute intra day volatility apart from traditional absolute and squared price changes. Volume is measured as average trade size. The basic hypotheses that the number of transactions drives the volatility rather than the volume has been examined by the cross-sectional averages of Nifty amp; Nifty Junior stocks after running time series regressions.

Book excerpt: We find that trading volume not only contributes positively to the contemporaneous volatility, as indicated in previous literature, but also contributes negatively to the subsequent volatility. And this pattern between trading volume and volatility is consistently held among individual stocks, volume-based portfolios, size-based portfolios, and market index, and among daily data and weekly data. These empirical findings tend to support that the Information-Driven-Trade (IDT) hypothesis is more pervasive and powerful in explaining trading activities in the stock market than the Liquidity-Driven-Trade (LDT) hypothesis. Our additional tests obtain three interesting findings, 1) liquidity and the degree of information asymmetry influence the relation between volume and subsequent volatility, 2) the effect of volume on subsequent volatility and volume size have a non-linear relationship, which is consistent with Barclay and Warner (1993, JFE)'s finding, 3) the effect of volume on subsequent volatility is asymmetry when the stock price moves up and when the stock price moves down, and we attribute this asymmetry to the short-selling constraints.

Download or read book Trading Volume Volatility and Return Dynamics written by Leon Zolotoy and published by . This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we study the dynamic relationship between trading volume, volatility, and stock returns at the international stock markets. First, we examine the role of volume and volatility in the individual stock market dynamics using a sample of ten major developed stock markets. Next, we extend our analysis to a multiple market framework, based on a large sample of cross-listed firms. Our analysis is based on both semi-nonparametric (Flexible Fourier Form) and parametric techniques. Our major findings are as follows. First, we find no evidence of the trading volume affecting the serial correlation of stock market returns, as predicted by Campbell et.al (1993) and Wang (1994). Second, the stock market volatility has a negative and statistically significant impact on the serial correlation of the stock market returns, consistent with the positive feedback trading model of Sentana and Wadhwani (1992). Third, the lagged trading volume is positively related to the stock market volatility, supporting the information flow theory. Fourth, we find the trading volume to have both an economically and statistically significant impact on the price discovery process and the co-movement between the international stock markets. Overall, these findings suggest the importance of the trading volume as an information variable.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we provide an overview of the concerns surrounding the variations in the calculation of risk-weighted assets (RWAs) across banks and jurisdictions and how this might undermine the Basel III capital adequacy framework. We discuss the key drivers behind the differences in these calculations, drawing upon a sample of systemically important banks from Europe, North America, and Asia Pacific. We then discuss a range of policy options that could be explored to fix the actual and perceived problems with RWAs, and improve the use of risk-sensitive capital ratios.

Available in PDF, EPUB and Kindle. Book excerpt: Linguistic taboo has been relegated for a long time to a peripheral position within Linguistics, due to its social stigmatization and inherent linguistic complexity. Recently, though, there has been a renewed interest in revisiting the phenomenon, especially from cognitive frameworks. This volume is the first collection of papers dealing with linguistic taboo from that perspective. The volume gathers 15 chapters, which provide novel insights into a broad range of taboo phenomena (euphemism, dysphemism, swearing, political correctness, coprolalia, etc.) from the fields of sexuality, diseases, death, war, ageing or religion. With a special focus on lexical semantics, the authors in the volume work within Cognitive Linguistics frameworks such as conceptual metaphor and metonymy, cultural conceptualization or cognitive sociolinguistics, but also at the interface of pragmatics, discourse analysis, applied linguistics, cognitive science or psychiatry. This volume provides theoretical reflections and case studies based on new methods and data from varied languages (English, Spanish, Polish, Dutch, Persian, Gikũyũ and Egyptian Arabic). As such, it moves towards a new generation of linguistic taboo studies.

Download or read book Rethinking Margin and Volatility written by Justin Balthrop and published by . This book was released on 2019 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper tests whether margin requirements cause asset price volatility. Using novel data on margin requirements and by exploiting exogenous variation from a threshold-based regression discontinuity design, I document that increasing margin causes a persistent decrease in future volatility (negative level effect) and a decline in trading volume. For an average 13.7% increase in margin requirement, I find an average 3.7% decrease in volatility. These results contrast with prior empirical studies that largely find no relationship between volatility and margin and provide support for the efficacy of financial market policies that seek to curb excess market volatility.

Download or read book The Chicago Plan Revisited written by Mr.Jaromir Benes and published by International Monetary Fund. This book was released on 2012-08-01 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the height of the Great Depression a number of leading U.S. economists advanced a proposal for monetary reform that became known as the Chicago Plan. It envisaged the separation of the monetary and credit functions of the banking system, by requiring 100% reserve backing for deposits. Irving Fisher (1936) claimed the following advantages for this plan: (1) Much better control of a major source of business cycle fluctuations, sudden increases and contractions of bank credit and of the supply of bank-created money. (2) Complete elimination of bank runs. (3) Dramatic reduction of the (net) public debt. (4) Dramatic reduction of private debt, as money creation no longer requires simultaneous debt creation. We study these claims by embedding a comprehensive and carefully calibrated model of the banking system in a DSGE model of the U.S. economy. We find support for all four of Fisher's claims. Furthermore, output gains approach 10 percent, and steady state inflation can drop to zero without posing problems for the conduct of monetary policy.

Download or read book Emerging Markets and the Global Economy written by Mohammed El Hedi Arouri and published by Academic Press. This book was released on 2013-12-26 with total page 927 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging Markets and the Global Economy investigates analytical techniques suited to emerging market economies, which are typically prone to policy shocks. Despite the large body of emerging market finance literature, their underlying dynamics and interactions with other economies remain challenging and mysterious because standard financial models measure them imprecisely. Describing the linkages between emerging and developed markets, this collection systematically explores several crucial issues in asset valuation and risk management. Contributors present new theoretical constructions and empirical methods for handling cross-country volatility and sudden regime shifts. Usually attractive for investors because of the superior growth they can deliver, emerging markets can have a low correlation with developed markets. This collection advances your knowledge about their inherent characteristics. Foreword by Ali M. Kutan Concentrates on post-crisis roles of emerging markets in the global economy Reports on key theoretical and technical developments in emerging financial markets Forecasts future developments in linkages among developed and emerging economies

Download or read book Economics and Politics Revisited written by Timothy Hellwig and published by Oxford University Press. This book was released on 2023-07-18 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: What drives government popularity? For decades, scholars, journalists, and political pundits alike have converged on a single answer: the economy. A rising economy lifts the popularity of the government, and if the economy's fortunes turn south, so too does that of the government. This conventional wisdom informs politicians' decisions as well as the scholarly commentary on parties and elections. Yet the conditions that underlie this model have changed in many countries as globalization has shifted control away from national policymakers, as non-economic cultural issues have risen in importance, and as our politics have become more polarized. At the same time, since the Great Recession in 2008 persistent economic volatility has kept the economy on the agenda. What, then, fuels government popularity in our current volatile environment? Are political fortunes tied to economic stability, as in the past? Or has the economy-popularity link-the popularity function-been severed by a host of new and less predictable factors in post-industrial societies? To answer these questions, Economics and Politics Revisited uses data from the Executive Approval Project (EAP), a cross-nationally comparable data on leader popularity, to model the fundamental dynamics of government support in advanced industrial democracies. Eleven country-specific chapters, each written by experts in the politics of the country, examine the role of economic performance in generating leader support in each country. In all cases, chapter authors show that the economy matters for popularity. However, the economy-popularity link is stronger in some countries than others. Further, chapters leverage EAP series to highlight change over time. Pooled analyses extend these findings, highlighting how the public's responses to the economy are reduced when political campaigns shift to non-economic issues and when parties are polarization on non-economic issues. Collectively, the volume highlights how evolving issue agendas are changing the nature of political accountability in advanced industrialized democracies. While the economy remains important, the book calls on students of political accountability to give greater attention to the role of non-economic issues.

Available in PDF, EPUB and Kindle. Book excerpt: "The book compares the 1954-79 labour productivity record of five expanding public sector industries to that of 24 expanding, capital intensive, mass-production industries in the British private sector. The author shows that the public sector industries' labour productivity growth was significantly faster than that of the private sector industries. Strikingly, he also finds that the state-owned industries were narrowing their productivity gap with their US counterparts at a significantly faster rate than the private sector industries. Dr. Iordanoglou concludes that it is possible that public ownership had - in the historical period investigated - a long-term positive effect on these industries."--BOOK JACKET.
