Book Synopsis Granger-Causal Analysis of Conditional Mean and Volatility Models by : Tomasz Woźniak
Download or read book Granger-Causal Analysis of Conditional Mean and Volatility Models written by Tomasz Woźniak and published by . This book was released on 2012 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent economic developments have shown the importance of spillover and contagion effects in financial markets as well as in macroeconomic reality. Such effects are not limited to relations between the levels of variables but also impact on the volatility and the distributions. Granger causality in conditional means and conditional variances of time series is investigated in the framework of several popular multivariate econometric models. Bayesian inference is proposed as a method of assessment of the hypotheses of Granger noncausality. First, the family of ECCC-GARCH models is used in order to perform inference about Granger-causal relations in second conditional moments. The restrictions for second-order Granger noncausality between two vectors of variables are derived. Further, in order to investigate Granger causality in conditional mean and conditional variances of time series VARMA-GARCH models are employed. Parametric restrictions for the hypothesis of noncausality in conditional variances between two groups of variables, when there are other variables in the system as well are derived. These novel conditions are convenient for the analysis of potentially large systems of economic variables. Bayesian testing procedures applied to these two problems, Bayes factors and a Lindley-type test, make the testing possible regardless of the form of the restrictions on the parameters of the model. This approach also enables the assumptions about the existence of higher-order moments of the processes required by classical tests to be relaxed. Finally, a method of testing restrictions for Granger noncausality in mean, variance and distribution in the framework of Markov-switching VAR models is proposed. Due to the nonlinearity of the restrictions derived by Warne (2000), classical tests have limited use. Bayesian inference consists of a novel Block Metropolis-Hastings sampling algorithm for the estimation of the restricted models, and of standard methods of computing posterior odds ratios. The analysis may be applied to financial and macroeconomic time series with changes of parameter values over time and heteroskedasticity.

Available in PDF, EPUB and Kindle. Book excerpt: Recent economic developments have shown the importance of spillover and contagion effects in financial markets. Such effects are not limited to relations between the levels of financial variables but also impact on their volatility. I investigate Granger causality in conditional mean and conditional variances of time series. For this purpose a VARMA-GARCH model is used. I derive parametric restrictions for the hypothesis of noncausality in conditional variances between two groups of variables, when there are other variables in the system as well. These novel conditions are convenient for the analysis of potentially large systems of economic variables. Such systems should be considered in order to avoid the problem of omitted variable bias. Further, I propose a Bayesian Lindley-type testing procedure in order to evaluate hypotheses of noncausality. It avoids the singularity problem that may appear in the Wald test. Also, it relaxes the assumption of the existence of higher-order moments of the residuals required for the derivation of asymptotic results of the classical tests. In the empirical example, I find that the dollar-to-Euro exchange rate does not second-order cause the pound-to-Euro exchange rate, in the system of variables containing also the Swiss frank-to-Euro exchange rate, which confirms the meteor shower hypothesis of Engle, Ito & Lin (1990).
Book Synopsis Introduction to Modern Time Series Analysis by : Gebhard Kirchgässner
Download or read book Introduction to Modern Time Series Analysis written by Gebhard Kirchgässner and published by Springer Science & Business Media. This book was released on 2012-10-08 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents modern developments in time series econometrics that are applied to macroeconomic and financial time series, bridging the gap between methods and realistic applications. It presents the most important approaches to the analysis of time series, which may be stationary or nonstationary. Modelling and forecasting univariate time series is the starting point. For multiple stationary time series, Granger causality tests and vector autogressive models are presented. As the modelling of nonstationary uni- or multivariate time series is most important for real applied work, unit root and cointegration analysis as well as vector error correction models are a central topic. Tools for analysing nonstationary data are then transferred to the panel framework. Modelling the (multivariate) volatility of financial time series with autogressive conditional heteroskedastic models is also treated.

This book was released on 2014-07-11 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies the information spillover among financial markets and explores the intraday effect and ACD models with high frequency data. This book also contributes theoretically by providing a new statistical methodology with comparative advantages for analyzing comovements between two time series. It explores this new method by testing the information spillover between the Chinese stock market and the international market, futures market and spot market. Using the high frequency data, this book investigates the intraday effect and examines which type of ACD model is particularly suited in capturing financial duration dynamics. The book will be of invaluable use to scholars and graduate students interested in comovements among different financial markets and financial market microstructure and to investors and regulation departments looking to improve their risk management.

Book Synopsis Modeling Phase Transitions in the Brain by : D. Alistair Steyn-Ross
Download or read book Modeling Phase Transitions in the Brain written by D. Alistair Steyn-Ross and published by Springer Science & Business Media. This book was released on 2010-03-14 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword by Walter J. Freeman. The induction of unconsciousness using anesthetic agents demonstrates that the cerebral cortex can operate in two very different behavioral modes: alert and responsive vs. unaware and quiescent. But the states of wakefulness and sleep are not single-neuron properties---they emerge as bulk properties of cooperating populations of neurons, with the switchover between states being similar to the physical change of phase observed when water freezes or ice melts. Some brain-state transitions, such as sleep cycling, anesthetic induction, epileptic seizure, are obvious and detected readily with a few EEG electrodes; others, such as the emergence of gamma rhythms during cognition, or the ultra-slow BOLD rhythms of relaxed free-association, are much more subtle. The unifying theme of this book is the notion that all of these bulk changes in brain behavior can be treated as phase transitions between distinct brain states. Modeling Phase Transitions in the Brain contains chapter contributions from leading researchers who apply state-space methods, network models, and biophysically-motivated continuum approaches to investigate a range of neuroscientifically relevant problems that include analysis of nonstationary EEG time-series; network topologies that limit epileptic spreading; saddle--node bifurcations for anesthesia, sleep-cycling, and the wake--sleep switch; prediction of dynamical and noise-induced spatiotemporal instabilities underlying BOLD, alpha-, and gamma-band Hopf oscillations, gap-junction-moderated Turing structures, and Hopf-Turing interactions leading to cortical waves.
Book Synopsis China's Global Political Economy by : Robert Taylor
Download or read book China's Global Political Economy written by Robert Taylor and published by Routledge. This book was released on 2018-04-27 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has been written about China’s economy, as well as its business management system. China's Global Political Economy, however, is designed to bring together these two perspectives, serving to enhance our understanding of China’s growing global role. Examining changes in the management strategies of foreign companies investing in China and Chinese enterprises doing business overseas, this book analyses China’s political economy in the context of the Communist Party’s changing policies. The introductory section begins by studying the aspects of Chinese economic growth as it impacts on domestic social issues and the projection of Chinese power abroad. Within this overall framework, it then goes on to critically assess the effects of foreign investment, business management strategies, human resource management, corporate social responsibility and the financial services sector. Arguing that the encouragement of consumption is a significant objective of the Chinese leadership, the last section is concerned with the importance of the food industry. This book will be of interest to students and scholars of Chinese business, management and international political economy, as well as policymakers and business practitioners.

Chapter 6 summarizes the main results obtained in each chapter and comments on the possible directions of future research.
Book Synopsis Volatility and Correlation by : Riccardo Rebonato
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
Book Synopsis Modelling and Forecasting in Dry Bulk Shipping by : Shun Chen
Download or read book Modelling and Forecasting in Dry Bulk Shipping written by Shun Chen and published by CRC Press. This book was released on 2014-04-24 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book models price behaviour and forecasts prices in the dry bulk shipping market, a major component of the world shipping industry. Recent uncertainties in the world economy, shipbuilding developments and fleet changes mean the dry bulk shipping market has become extremely volatile, highly speculative and more sensitive to external shocks. In response to these challenging circumstances, this book models price behaviour and forecasts prices in various markets including the freight market, the new build ship market and the second-hand ship market. The authors have carried out an extensive investigation of dry bulk shipping over a 60-year period in diverse sub-markets, trading routes, market conditions and dry bulk vessels. The authors also propose a framework for analysing and modelling the economic processes of numerous variables in the dry bulk shipping market, making use of modern econometric techniques and other economic approaches. This will be especially useful for the control and assessment of risk for ship owners and charterers in ship operation, ship chartering and ship trading activities. This book will be extremely useful for shipbuilders, owners and charterers, as well as shipping analysts and policymakers. It will also be of great interest to academics and researchers concerned with the economics of the shipping industry.

Book Synopsis Efficiency and Volatility Dynamics of Bangladesh's Stock Market by : Md Abu Hasan
Download or read book Efficiency and Volatility Dynamics of Bangladesh's Stock Market written by Md Abu Hasan and published by Cambridge Scholars Publishing. This book was released on 2024-02-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to empirical finance by comprehensively analysing an emerging stock market, employing modern econometric techniques. The most central and fascinating area of financial economics is probably the efficiency and volatility of the stock market – however, studies of emerging economies are relatively limited in this area. The rising importance of stock market globalisation has increased interest in emerging markets. This book leads the way for an emerging market perspective, as it explores the issue of efficiency and volatility of the stock market in Bangladesh by employing both univariate and multivariate models, using daily data of past share prices and monthly data of macroeconomic variables and the stock index, respectively. This book offers an understanding of the crucial issues facing developing economies, particularly emerging stock markets with similar characteristics to those of Bangladesh. This book undoubtedly provides valuable information for investors in the stock market, graduate, post-graduate, and PhD students in quantitative financial economics, academics in economics and finance, and policymakers in developing economies.
