Download or read book Dynamic Models for Volatility and Heavy Tails written by Andrew C. Harvey and published by Cambridge University Press. This book was released on 2013-04-22 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volatility of financial returns changes over time and, for the last thirty years, Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models have provided the principal means of analyzing, modeling and monitoring such changes. Taking into account that financial returns typically exhibit heavy tails - that is, extreme values can occur from time to time - Andrew Harvey's new book shows how a small but radical change in the way GARCH models are formulated leads to a resolution of many of the theoretical problems inherent in the statistical theory. The approach can also be applied to other aspects of volatility. The more general class of Dynamic Conditional Score models extends to robust modeling of outliers in the levels of time series and to the treatment of time-varying relationships. The statistical theory draws on basic principles of maximum likelihood estimation and, by doing so, leads to an elegant and unified treatment of nonlinear time-series modeling.

Download or read book Financial and Macroeconomic Connectedness written by Francis X. Diebold and published by Oxford University Press. This book was released on 2015-02-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Connections among different assets, asset classes, portfolios, and the stocks of individual institutions are critical in examining financial markets. Interest in financial markets implies interest in underlying macroeconomic fundamentals. In Financial and Macroeconomic Connectedness, Frank Diebold and Kamil Yilmaz propose a simple framework for defining, measuring, and monitoring connectedness, which is central to finance and macroeconomics. These measures of connectedness are theoretically rigorous yet empirically relevant. The approach to connectedness proposed by the authors is intimately related to the familiar econometric notion of variance decomposition. The full set of variance decompositions from vector auto-regressions produces the core of the 'connectedness table.' The connectedness table makes clear how one can begin with the most disaggregated pair-wise directional connectedness measures and aggregate them in various ways to obtain total connectedness measures. The authors also show that variance decompositions define weighted, directed networks, so that these proposed connectedness measures are intimately related to key measures of connectedness used in the network literature. After describing their methods in the first part of the book, the authors proceed to characterize daily return and volatility connectedness across major asset (stock, bond, foreign exchange and commodity) markets as well as the financial institutions within the U.S. and across countries since late 1990s. These specific measures of volatility connectedness show that stock markets played a critical role in spreading the volatility shocks from the U.S. to other countries. Furthermore, while the return connectedness across stock markets increased gradually over time the volatility connectedness measures were subject to significant jumps during major crisis events. This book examines not only financial connectedness, but also real fundamental connectedness. In particular, the authors show that global business cycle connectedness is economically significant and time-varying, that the U.S. has disproportionately high connectedness to others, and that pairwise country connectedness is inversely related to bilateral trade surpluses.

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 Volatility and Correlation written by Riccardo Rebonato and published by John Wiley & Sons. This book was released on 2005-07-08 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Volatility and Correlation 2nd edition: The Perfect Hedger and the Fox, Rebonato looks at derivatives pricing from the angle of volatility and correlation. With both practical and theoretical applications, this is a thorough update of the highly successful Volatility & Correlation – with over 80% new or fully reworked material and is a must have both for practitioners and for students. The new and updated material includes a critical examination of the ‘perfect-replication’ approach to derivatives pricing, with special attention given to exotic options; a thorough analysis of the role of quadratic variation in derivatives pricing and hedging; a discussion of the informational efficiency of markets in commonly-used calibration and hedging practices. Treatment of new models including Variance Gamma, displaced diffusion, stochastic volatility for interest-rate smiles and equity/FX options. The book is split into four parts. Part I deals with a Black world without smiles, sets out the author’s ‘philosophical’ approach and covers deterministic volatility. Part II looks at smiles in equity and FX worlds. It begins with a review of relevant empirical information about smiles, and provides coverage of local-stochastic-volatility, general-stochastic-volatility, jump-diffusion and Variance-Gamma processes. Part II concludes with an important chapter that discusses if and to what extent one can dispense with an explicit specification of a model, and can directly prescribe the dynamics of the smile surface. Part III focusses on interest rates when the volatility is deterministic. Part IV extends this setting in order to account for smiles in a financially motivated and computationally tractable manner. In this final part the author deals with CEV processes, with diffusive stochastic volatility and with Markov-chain processes. Praise for the First Edition: “In this book, Dr Rebonato brings his penetrating eye to bear on option pricing and hedging.... The book is a must-read for those who already know the basics of options and are looking for an edge in applying the more sophisticated approaches that have recently been developed.” —Professor Ian Cooper, London Business School “Volatility and correlation are at the very core of all option pricing and hedging. In this book, Riccardo Rebonato presents the subject in his characteristically elegant and simple fashion...A rare combination of intellectual insight and practical common sense.” —Anthony Neuberger, London Business School

Download or read book International Financial Contagion written by Stijn Claessens and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: No sooner had the Asian crisis broken out in 1997 than the witch-hunt started. With great indignation every Asian economy pointed fingers. They were innocent bystanders. The fundamental reason for the crisis was this or that - most prominently contagion - but also the decline in exports of the new commodities (high-tech goods), the steep rise of the dollar, speculators, etc. The prominent question, of course, is whether contagion could really have been the key factor and, if so, what are the channels and mechanisms through which it operated in such a powerful manner. The question is obvious because until 1997, Asia's economies were generally believed to be immensely successful, stable and well managed. This question is of great importance not only in understanding just what happened, but also in shaping policies. In a world of pure contagion, i.e. when innocent bystanders are caught up and trampled by events not of their making and when consequences go far beyond ordinary international shocks, countries will need to look for better protective policies in the future. In such a world, the international financial system will need to change in order to offer better preventive and reactive policy measures to help avoid, or at least contain, financial crises.

Download or read book Shadow Banking System written by Tobias Adrian and published by DIANE Publishing. This book was released on 2010-10 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current financial crisis has highlighted the growing importance of the ¿shadow banking system,¿ which grew out of the securitization of assets and the integration of banking with capital market developments. This trend has been most pronounced in the U.S., but it has had a profound influence on the global financial system. Securitization was intended as a way to transfer credit risk to those better able to absorb losses, but instead it increased the fragility of the entire financial system by allowing banks and other intermediaries to ¿leverage up¿by buying one another¿s securities. In the new, post-crisis financial system, the role of securitization will likely be held in check by more stringent financial regulation. Charts and tables.

Download or read book Network Effects of International Shocks and Spillovers written by Mr.Alexei Kireyev and published by International Monetary Fund. This book was released on 2015-07-07 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes a method for assessing international spillovers from nominal demand shocks. It quantifies the impact of a shock in one country on all other countries. The paper concludes that the network effects in shock spillovers can be substantial, comparable, and often exceed the initial shock. Individual countries may amplify, absorb, or block spillovers. Most developed countries pass-through shocks, whereas low-income countries and oil exporters tend to block shock spillovers. The method is used to study demand shocks originating from a large and medium country, China and Ukraine respectively.

Download or read book Hysteresis and Business Cycles written by Ms.Valerie Cerra and published by International Monetary Fund. This book was released on 2020-05-29 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Download or read book Asian Contagion written by Karl Jackson and published by Routledge. This book was released on 2018-03-05 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: For much of the second half of the twentieth century, the Asian economic "miracle" has fueled the greatest expansion of wealth for the largest population in the history of mankind. In the summer of 1997, thirty years of economic boom came crashing back to earth. The reality of unrestrained speculation, inefficiently regulated currency exchange, banking instability and bad loans have struck the much-vaunted "Asian Tigers" like Thailand, Indonesia, Korea, and, finally, Japan, casting a shadow of uncertainty on a region recently to the fore in the world economic system. Recovery depends largely on reform within the Asian economies themselves and a cold assessment of the structural weaknesses that lay under the surface, but only now have come to light. The implications for world economies and, more broadly, the dynamics of world politics, are tremendous.

Download or read book Does Financial Connectedness Predict Crises written by Ms.Camelia Minoiu and published by International Monetary Fund. This book was released on 2013-12-24 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global financial crisis has reignited interest in models of crisis prediction. It has also raised the question whether financial connectedness - a possible source of systemic risk - can serve as an early warning indicator of crises. In this paper we examine the ability of connectedness in the global network of financial linkages to predict systemic banking crises. Our results indicate that increases in a country's financial interconnectedness and decreases in its neighbors' connectedness are associated with a higher probability of banking crises after controlling for macroeconomic fundamentals.
