This book was released on 2012 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the theoretical and empirical aspects of financial market volatility. Financial markets are essentially volatile. However, excess volatility may impair the smooth functioning of the financial system and economic performance. Volatility that was evident in financial markets during the recent financial crisis, and, even more recently, during the European debt crisis, has attracted renewed interest in studying volatility. The most prominent feature of this crisis was its widespread effects on the financial markets of developed countries, while leaving emerging markets as the success story. The main objectives of this thesis are twofold. The first is to quantify and investigate the nature of the factors behind the transmission of volatility on and among financial markets during the crisis of 2007-2011, with a special focus on developed countries. Both analytical and empirical modeling approaches are used. The analytical approach in Chapter 2 is built up on the herd behavior of international investors, using the role of carry traders' as a conduit. Particular attention is given to modeling the way in which private signals on margin requirements lead some investors to change their decisions, and how their strategic behavior transmits shocks across countries. Chapter 3 adopts an empirical approach using a latent factor methodology, and aims to explore the transmission mechanisms of the crisis through equity and bond markets over different phases of the crisis of 2007-2011. The factor model in particular specifies contagion channels through cross-country and cross-market contagion linkages, after controlling for other forms of fundamentals through the factor structure. The second objective of the thesis is to examine whether and how successfully emerging market central banks attempt to shield their domestic currency market from externally sourced financial market volatility through foreign exchange intervention. Two empirical approaches, the generalized autoregressive heteroskedasticity approach in Chapter 4 and the latent factor approach in Chapter 5, are used to explore the significance and effectiveness of foreign exchange intervention using a unique data set of daily intervention obtained from the Central Bank of Sri Lanka. Overall, this thesis finds strong evidence for the transmission of asset market volatility across developed countries during the crisis of 2007-2011. Through herd behavior and the feedback effects in asset prices and exchange rates, financial markets can be destabilized during crises. Financial market contagion is another significant channel through which the stability in the financial system can be compromised, and several channels of contagion are identified and estimated for different phases of the crisis. However, the relative importance of each contagion channel varies depending on the source asset market and the phase of the crisis. Turning to emerging market responses to periods of global volatility, foreign exchange intervention is found to be an effective policy instrument for shielding against external shocks, as is evident for Sri Lanka. Intervention is aimed to ""lean against the wind"" to reduce volatility and to accumulate international reserves. The central bank responds to global movements in currency markets when intervening, rather than movements specific to the domestic currency market. -- provided by Candidate.

Download or read book Stochastic Volatility in Financial Markets written by Antonio Mele and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stochastic Volatility in Financial Markets presents advanced topics in financial econometrics and theoretical finance, and is divided into three main parts. The first part aims at documenting an empirical regularity of financial price changes: the occurrence of sudden and persistent changes of financial markets volatility. This phenomenon, technically termed `stochastic volatility', or `conditional heteroskedasticity', has been well known for at least 20 years; in this part, further, useful theoretical properties of conditionally heteroskedastic models are uncovered. The second part goes beyond the statistical aspects of stochastic volatility models: it constructs and uses new fully articulated, theoretically-sounded financial asset pricing models that allow for the presence of conditional heteroskedasticity. The third part shows how the inclusion of the statistical aspects of stochastic volatility in a rigorous economic scheme can be faced from an empirical standpoint.

Download or read book Asset Prices Booms and Recessions written by Willi Semmler and published by Springer Science & Business Media. This book was released on 2007-03-21 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Asset Prices, Booms and Recessions" is a book on Financial Economics from a dynamic perspective. It focuses on the dynamic interaction of financial markets and economic activity. The financial markets to be studied here encompasses the money and bond market, credit market, stock market and foreign exchange market. Economic activity is described by the activity of firms, banks, households, governments and countries. The book shows how economic activity affects asset prices and the financial market and how asset prices and financial market volatility feed back to economic activity. The focus in this book is on theories, dynamic models and empirical evidence. Empirical applications relate to episodes of financial instability and financial crises of the U.S., Latin American, Asian as well as Euro-area countries. The current version of the book has moved to a more extensive coverage of the topics in financial economics by updating the literature in the appropriate chapters. Moreover it gives a more extensive treatment of new and more advanced topics in financial economics such as international portfolio theory, multi-agent and evolutionary approaches, capital asset pricing beyond consumption-based models and dynamic portfolio decisions. Overall, the book presents material that researchers and practitioners in financial engineering need to know about economic dynamics and that economists, practitioners and policy makers need to know about the financial market.

Download or read book Financial Market Volatility and the Implications for Market Regulation written by Louis O. Scott and published by International Monetary Fund. This book was released on 1990-11-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volatility in financial markets has forced economists to reexamine the validity of the efficient markets hypothesis, and new empirical approaches have been applied to the study of this important issue in recent years. Many of the recent studies have found evidence of excessive volatility. In the aftermath of the stock market crash of 1987 and the perceived increase in market volatility, some economists have advocated additional market regulations. Are these proposed regulations necessary and would they serve to reduce market volatility? This paper presents a review of recent studies on financial market volatility and examines the proposed regulations.

This book was released on 2013-03-09 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Empirical Studies on Volatility in International Stock Markets describes the existing techniques for the measurement and estimation of volatility in international stock markets with emphasis on the SV model and its empirical application. Eugenie Hol develops various extensions of the SV model, which allow for additional variables in both the mean and the variance equation. In addition, the forecasting performance of SV models is compared not only to that of the well-established GARCH model but also to implied volatility and so-called realised volatility models which are based on intraday volatility measures. The intended readers are financial professionals who seek to obtain more accurate volatility forecasts and wish to gain insight about state-of-the-art volatility modelling techniques and their empirical value, and academic researchers and students who are interested in financial market volatility and want to obtain an updated overview of the various methods available in this area.

Download or read book Market Liquidity written by Thierry Foucault and published by Oxford University Press. This book was released on 2023 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--

Available in PDF, EPUB and Kindle. Book excerpt: Published in 1999. The issue of financial volatility, especially since financial deregulation, has given rise to concerns regarding the effects of increased financial volatility on real economic activity. Two issues represent a substantial challenge to financial economists with respect to these concerns. The first relates to the identification of the causes of increased volatility in financial markets. Identification is a first step towards increasing both financial economists' and policy-makers' understanding of the interrelated causes of financial volatility. The second requires linking the effects of increased financial volatility to the real sector of the economy by examining the channels through which financial volatility influences fundamental economic variables. In order to address these two issues, the analysis initially develops and estimates a model which is capable of explaining the financial and business cycle determinates of movements in the conditional volatility of the Australian All Industrials stock market index. Evidence suggests that a significant linkage exists between the conditional volatility of the money supply. Models are then developed to examine how monetary volatility is transmitted to the volatility of financial asset prices, inflation and real output in an open economy. The results indicate that while financial volatility has increased to some extent since the late 1980s, this has been transferred non-uniformly towards increasing volatility of both real and financial activity.

Download or read book Financial Markets Theory written by Emilio Barucci and published by Springer. This book was released on 2017-06-08 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, now in a thoroughly revised second edition, presents the economic foundations of financial markets theory from a mathematically rigorous standpoint and offers a self-contained critical discussion based on empirical results. It is the only textbook on the subject to include more than two hundred exercises, with detailed solutions to selected exercises. Financial Markets Theory covers classical asset pricing theory in great detail, including utility theory, equilibrium theory, portfolio selection, mean-variance portfolio theory, CAPM, CCAPM, APT, and the Modigliani-Miller theorem. Starting from an analysis of the empirical evidence on the theory, the authors provide a discussion of the relevant literature, pointing out the main advances in classical asset pricing theory and the new approaches designed to address asset pricing puzzles and open problems (e.g., behavioral finance). Later chapters in the book contain more advanced material, including on the role of information in financial markets, non-classical preferences, noise traders and market microstructure. This textbook is aimed at graduate students in mathematical finance and financial economics, but also serves as a useful reference for practitioners working in insurance, banking, investment funds and financial consultancy. Introducing necessary tools from microeconomic theory, this book is highly accessible and completely self-contained. Advance praise for the second edition: "Financial Markets Theory is comprehensive, rigorous, and yet highly accessible. With their second edition, Barucci and Fontana have set an even higher standard!"Darrell Duffie, Dean Witter Distinguished Professor of Finance, Graduate School of Business, Stanford University "This comprehensive book is a great self-contained source for studying most major theoretical aspects of financial economics. What makes the book particularly useful is that it provides a lot of intuition, detailed discussions of empirical implications, a very thorough survey of the related literature, and many completely solved exercises. The second edition covers more ground and provides many more proofs, and it will be a handy addition to the library of every student or researcher in the field."Jaksa Cvitanic, Richard N. Merkin Professor of Mathematical Finance, Caltech "The second edition of Financial Markets Theory by Barucci and Fontana is a superb achievement that knits together all aspects of modern finance theory, including financial markets microstructure, in a consistent and self-contained framework. Many exercises, together with their detailed solutions, make this book indispensable for serious students in finance."Michel Crouhy, Head of Research and Development, NATIXIS

Each chapter develops statistical techniques within the context of a particular financial application. This exciting new text contains a unique and accessible combination of theory and practice, bringing state-of-the-art statistical techniques to the forefront of financial applications. Each chapter also includes a discussion of recent empirical evidence, for example, the rejection of the Random Walk Hypothesis, as well as problems designed to help readers incorporate what they have read into their own applications.

Download or read book Empirical Asset Pricing written by Wayne Ferson and published by MIT Press. This book was released on 2019-03-12 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.

Download or read book Long Memory in the Volatility of Indian Financial Market written by Dilip Kumar and published by . This book was released on 2014-02 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professorial Dissertation from the year 2014 in the subject Business economics - Investment and Finance, grade: A, language: English, abstract: This book examines the long memory characteristics in the volatility of the Indian stock market, the Indian exchange rates and the Indian banking sector. This book also reviews the chain of approaches to estimate the long memory parameter. The long memory characteristics of the financial time series are widely studied and have implications for various economics and finance theories. The most important financial implication is related to the violation of the weak-form of market efficiency which encourages the traders, investors and portfolio managers to develop models for making predictions and to construct and implement speculative trading and investment strategies. In an efficient market, the price of an asset should follow a random walk process in which the price change is unaffected by its lagged price changes and has no memory.

This book was released on 2010-03-16 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (undergraduate) from the year 2010 in the subject Business economics - General, grade: 1,3, University of Applied Sciences Northwestern Switzerland, language: English, abstract: The Efficient market hypothesis can be considered as part of rational economics but it does not specify at all how individuals should or will act. Therefore it might be a useful model of the functioning of the market as a whole but it does not explain the behaviors of investors as well as managers and other participants. While the Efficient market hypothesis deals as a basis for understanding the normal working of the markets, from time to time it might happen that the market as a whole or an individual stock may act irrationally. Such behavior is well known and generally occurs when the market price of a share turns away from its intrinsic value. The result is what commonly is called a bubble. This term is often used but the reasons for the occurrence are quite unclear. In fact, at the same time as the market as a whole has become more efficient, instances of irrationality have become more common or at least appear to be. Therefore we try to discuss the question why capital markets, which are considered as efficient and perfect in theory, are volatile and imperfect in reality. The paper responds to this question by discussing mainly the irrational behavior of people by turning into the field of psychology. Furthermore it seeks for approaches of explanation conducted by different investment strategies containing among others an increased use of derivative instruments or single trades based on massive capacity which therefore influence prices. Methodology and Structure of the paper In general the paper can be divided in 3 parts, a theoretical as well as an analytical one and a final point the Conclusion (Part C) which sums up the basic findings of the paper. Whereas Part A can be regarded as delivering the theoretical background, Part B contains the empirical analysis based on several case studies. Chapter 1, 2 and 3 are providing the reader with the needed knowledge of the capital market, volatility and the efficient market hypothesis in order to assure the understanding of the more complex prosecution of the paper After discussing those fundamentals the paper soon takes a view on some instances of irrationality in Part B, but first of all delivers in Chapter 4, 5 and 6 some theories that attempt to explain such irrationalities. Finally the paper is finished by linking those theories with the observed instances of irrationality
