Book Description
This thesis analyses three sets of issues: 1) the cyclical behaviour of the Chinese stock markets, 2) the fitness of using realized volatility (RV) in the generalized autoregressive conditional heteroskedasticity (GARCH) model, and 3) the volatility spillover between the Chinese and Australian stock markets. After conducting an extensive literature review, the thesis examines the three sets of issues separately.First, a Markov regime switching model is applied to analyse the bull and bear cycles in the Chinese stock market, since the cycles of bull and bear markets can reflect economic development and investor confidence. Specifically, grouping stocks by industry and firm size, the results show the following: 1) Bear cycles between stocks and the index overlap heavily, indicating strong herding effects. A long bear market cycle is found and can be explained by widely diversified stock performance across the markets. 2) Certain shocks to one industry could have different impacts on the Shanghai and Shenzhen stock markets. 3) Firm size can have a significant impact on the performance of stocks in bull or bear cycles.The second topic focuses on estimating the RV of the Chinese stock markets and comparing it with the GARCH model. The actual volatility is inherently unobserved, while the RV could be treated as being directly observable and then be used to study time-varying behaviour and forecasting. Thus, a large number of studies use RV in GARCH models for volatility analysis. However, there is yet no study that discusses the correlation between RV and GARCH while using RV in GARCH models. This could lead to bias in estimation because of the different properties of RV and GARCH. The results show that GARCH models combined with RV could be more suitable for estimating volatility for large firms. When the firms are grouped in terms of positive/negative returns, similar results are found as when firms are grouped by firm size.The third topic estimates the volatility spillover between the Chinese and Australian stock markets, motivated by the lack of attention to spillover between these two markets in the literature. While economic interdependence between Australia and China has soared during the last two decades due to China's tight reliance on Australia's mining and resources, little research attention has been paid to these two countries. This study fills the literature gap and assesses the volatility spillover between the Chinese and Australian stock markets based on the CSI300 and ASX200 industry indices. To the best of my knowledge, this is the first study using Chinese industry data to discuss volatility spillover. The key findings of the thesis are that volatility spillover across these two markets is bidirectional, while there is one-sided or insignificant spillover across industries between these two countries. The findings of the thesis fill the literature gap, help clarify the debate about volatility spillover between the Chinese stock market and the world market, and provide a clearer idea of the channels through which volatility is transmitted across countries.

Book Description
"This paper reviews the commonly used multivariate GARCH models and uses the daily data of the four Greater China region stock markets, namely Hongkong, Shanghai,Shenzhen, and Singapore, and data of Japan as one exogenous variable to investigate the volatility and shocks spillover behavior and to establish the market linkage among the four markets. We find that the volatility spillover between Shanghai and Shenzhen is obvious and correlation contagion is detected. Conditional variance and conditional correlations are time varying and dynamic which conforms to the arguments in most of the literature. Shanghai and Shenzhen present a very high correlation level during the sampling period, varying from 0.75 to 0.98, at some point even near linear correlation, which is not uncommon due to the close interlink between the two markets. Hongkong and Singapore presents a mildly high correlation, varying from 0.25 to 0.9, with an average of 0.62. However, the correlation is very volatile. Results present the convincing evidence that Chinese stock markets are more and more integrated to the global markets and the Greater China region markets are more integrated to each other. There are many obvious correlation breaks, when all the correlations suddenly drop to a drastically low level. The drop corresponds to the actual economic event as we discover."--Author's abstract.

Book Description
This volume of "International Finance Review" focuses on the Asia-Pacific financial markets. A total of 22 original papers, not published elsewhere, have been selected from a competitive field. These papers utilize a variety of methods, including theoretical, empirical and qualitative to highlight a range of issues across the region. Several papers offer combinations of these different categories and among the empirical papers, there are a wide variety of datasets analyzed. While China does play a significant part in the analysis of five of the papers in this volume (this is to be expected given its importance in the region), a host of other countries are also considered. This ensures the volume is truly international in its scope. These papers each serve to contribute to the knowledge on a particular issue related to the financial markets within this region and for this volume, three main issues have been identified: integration, innovation and challenges. Articles are contributed by experts in their fields. It is truly international in scope.

Book Description
This book contains several innovative models for the prices of financial assets. First published in 1986, it is a classic text in the area of financial econometrics. It presents ARCH and stochastic volatility models that are often used and cited in academic research and are applied by quantitative analysts in many banks. Another often-cited contribution of the first edition is the documentation of statistical characteristics of financial returns, which are referred to as stylized facts. This second edition takes into account the remarkable progress made by empirical researchers during the past two decades from 1986 to 2006. In the new Preface, the author summarizes this progress in two key areas: firstly, measuring, modelling and forecasting volatility; and secondly, detecting and exploiting price trends. Sample Chapter(s). Chapter 1: Introduction (1,134 KB). Contents: Features of Financial Returns; Modelling Price Volatility; Forecasting Standard Deviations; The Accuracy of Autocorrelation Estimates; Testing the Random Walk Hypothesis; Forecasting Trends in Prices; Evidence Against the Efficiency of Futures Markets; Valuing Options; Appendix: A Computer Program for Modelling Financial Time Series. Readership: Academic researchers in finance & economics; quantitative analysts.

Book Description
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.

Book Description
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.
