We adopt a BEKK-GARCH framework and employ a systematic approach to jointly examine structural breaks in the Hong Kong cash index and index futures volatility and volatility spillovers from the S&P 500 cash and futures. Multiple switching dummy variables are included in the variance equations to...

In an earlier paper we adopted a Bi-variate BEKK-GARCH framework and employed a systematic approach to examine structural breaks in the Hang Seng Index and Index Futures market volatility. Switching dummy variables were included and tested in the variance equations to check for any structural...

This paper analyses Private Placements for the Australian biotechnology sector. Private placement is one of the favoured methods of secondary equity offering around the world. However, it is also the least studied corporate financing mechanism. A major issue around private placement is the...

Using different unconditional and conditional versions of the bivariate BEKK-GARCH model of Engle and Kroner, we calculate time-varying hedge ratios for Indian stock futures market involving a cross-section of seven firms across a spectrum of industries. These models are solved not only with the...

While there has been much judicial discussion regarding the competency of Australia’s continuous disclosure regime with reference to contemporaneous international standards, there has to date been limited empirical analysis of the Australian system’s effectiveness in preventing selective...

Contemporaneous transmission effects across volatilities of the Hong Kong Stock and Index futures markets and futures volume of trade are tested by employing a structural systems approach. Competing measures of volatility spillover, constructed from the overnight U.S. S&P500 index futures, are...

The extremely high A- share under-pricing in China’s primary market provides us with a very interesting area of empirical research. Previous studies on China’s IPO underpricing have been suggestive, but in-conclusive. A significant decline in A- share underpricing is found in 2003 relative...

Simultaneous Volatility models are developed and shown to be separate from Multivariate GARCH estimators. An example is provided that allows for simultaneous and uni-directional volatility and volume of trade effects. These effects are tested using intra-day data from the Australian cash index...
