Book Description
Transmission mechanisms in financial markets reflect the degree of integration of capital markets and of real economies. As a matter of fact, volatility has components which may behave differently across quiet and turbulent periods, but appear to behave in similar ways from market to market. In this paper we suggest a Multiplicative Error Model (MEM) approach which is suitable for modeling directly the conditional expectation of the market daily range which is a good proxy for volatility. In the present context, the dynamics of the expected volatility of one market is extended to include interactions with the past daily ranges of other markets, thus building a potentially fully interdependent model. We analyze eight East Asian markets in the period 1995-2006, devoting particular attention to the treatment of the 1997-1998 turbulence period. We show that for some of the markets there is no evidence of changes in the dynamic impacts within the crisis and without and for other markets such a change is limited to a level shift: this suggests that the links may have been stable across sub-periods.

Book Description
This article examines the extent of contagion and interdependence across the East Asian equity markets since early 1990s and compares the ongoing crisis with earlier episodes. Using the forecast error variance decomposition from a vector autoregression, we derive return and volatility spillover indices over the rolling sub-sample windows. We show that there is substantial difference between the behavior of the East Asian return and volatility spillover indices over time. While the return spillover index reveals increased integration among the East Asian equity markets, the volatility spillover index experiences significant bursts during major market crises, including the East Asian crisis. The fact that both return and volatility spillover indices reached their respective peaks during the current global financial crisis attests to the severity of the current episode. -- Stock returns ; Volatility ; Spillovers ; Vector autoregression ; Variance decomposition

Book Description
This paper examines the changing nature of volatility spillovers among the U.S. and eight East Asian stock markets between two financial crises: the Asian currency crisis and the U.S. subprime credit crisis. Our empirical results suggest that volatility is not always spilled over from directly affected markets to surrounding markets in crisis periods. The East Asian markets who directly suffered from the Asian currency crisis are the ones to which volatility is spilled over from other markets during the Asian currency crisis period, whereas unidirectional volatility spillovers from the U.S. market to other markets are observed during both crisis periods. This difference can be explained by a predetermined hierarchy in which volatility spillovers tend to start from the U.S. market regardless of the geographical origin of the crisis. Furthermore, our results reveal that the markets in three major Asian financial hubs, i.e., Japan, Hong Kong and Singapore, are the markets to which volatility is spilled over unidirectionally from several other countries during the subprime credit crisis period, whereas it is not true during the Asian currency crisis period. We attribute this difference to crisis-specific (currency or credit crisis), market-specific (credit derivatives market participation and foreign currency reserves), and time-specific (more integrated global market) factor.

Book Description
This article examines the volatility spillover effects among six Asian country stock markets and the United States. The six Asian countries are India, Hong Kong, South Korea, Japan, Singapore, and Taiwan. This article also investigates whether the volatility spillover effect increased after the 1997 Asian financial crisis. There are statistically significant volatility spillover effects within the stock markets of these countries and that effect dramatically increased after the 1997 Asian financial crisis. Especially, the regionally close five countries Hong Kong, South Korea, Japan, Singapore, and Taiwan experienced more links among them.

Book Description
This paper examines volatility spillovers from mature to emerging stock markets and tests for changes in the transmission mechanism-contagion-during turbulences in mature markets. Tri-variate GARCH-BEKK models of returns in global (mature), regional, and local markets are estimated for 41 emerging market economies (EMEs), with a dummy capturing parameter shifts during turbulent episodes. LR tests suggest that mature markets influence conditional variances in many emerging markets. Moreover, spillover parameters change during turbulent episodes. Conditional variances in most EMEs rise during these episodes, but there is only limited evidence of shifts in conditional correlations between mature and emerging markets.

Book Description
Despite the increasingly tight economic relationship between China and Australia, little attention has been paid to the analysis of stock market volatility spillover across these two countries. This paper, based on industry data, fills the gap in the literature and provides a clear idea of the channels through which volatility is transmitted across countries. This paper finds that the volatility spillover across these two markets is bidirectional while there is single or insignificant spillover across industries between these two countries. More specifically, the results of the Granger causality test show that the stock market volatility spillover is bidirectional between these two markets in the financial, health care, industrials, information technology, and materials industries. One-way volatility spillover exists in the consumer staples industry and there is insignificant volatility spillover in the energy, telecommunications, and utilities industries between the Chinese and Australian stock markets.

Book Description
Purpose - This paper aims to study the daily returns and volatility spillover effects in common stock prices between China and four countries in Southeast Asia (Vietnam, Thailand, Singapore and Malaysia).Design/methodology/approach - The analysis uses a vector autoregression with a bivariate GARCHBEKK model to capture return linkage and volatility transmission spanning the period including the pre- and post-2008 Global Financial Crisis.Findings - The main empirical result is that the volatility of the Chinese market has had a significant impact on the other markets in the data sample. For the stock return, linkage between China and other markets seems to be remarkable during and after the Global Financial Crisis. Notably, the findings also indicate that the stock markets are more substantially integrated into the crisis.Practical implications - The results have considerable implications for portfolio managers and institutional investors in the evaluation of investment and asset allocation decisions. The market participants should pay more attention to assess the worth of across linkages among the markets and their volatility transmissions. Additionally, international portfolio managers and hedgers may be better able to understand how the volatility linkage between stock markets interrelated overtime; this situation might provide them benefit in forecasting the behavior of this market by capturing the other market information.Originality/value - This paper would complement the emerging body of existing literature by examining how China stock market impacts on their neighboring countries including Vietnam, Thailand, Singapore and Malaysia. Furthermore, this is the first investigation capturing return linkage and volatility spill over between China market and the four Southeast Asian markets by using bivariate VAR-GARCH-BEKK model. The authors believe that the results of this research's empirical analysis would amplify the systematic understanding of spillover activities between China stock market and other stock markets.

Book Description
This paper assesses financial integration in Asia in terms of risk-sharing benefit versus financial-contagion cost. We construct a new measure of risk sharing based on a term structure model, which allows identification of realized stochastic discount factors. Risk sharing is low in Asia, and varies across time and countries, whereas contagion risks are more significant intra-regionally, and relatively stable over the past decade. An overall tradeoff exists between risk sharing and contagion, but the terms of tradeoffs vary across countries, depending on relative economic fluctuations and inflation differentials. Asia, therefore, can potentially enhance risk sharing without raising contagion risk.

Book Description
Mathematical finance plays a vital role in many fields within finance and provides the theories and tools that have been widely used in all areas of finance. Knowledge of mathematics, probability, and statistics is essential to develop finance theories and test their validity through the analysis of empirical, real-world data. For example, mathematics, probability, and statistics could help to develop pricing models for financial assets such as equities, bonds, currencies, and derivative securities.
