Introduction of electronic trading in index futures : volatility and volume effects

There is continuing debate in the US over full introduction of electronic trading in those index futures contracts that are still traded at the CME via open outcry. Since the late 1990s major international exchanges trading index futures contracts have converted to full electronic trading. Recent empirical studies have focused on effects on bid/ask spreads and related price volatility following these changes. We take a different approach and investigate and test for structural change in conditional volatility and volume effects following the shift to electronic trading in the Australian Share Price Index futures contract. Multiple Switching point GARCH models are employed with the data sampled at 5, 15 and 30-minute intervals from transaction records supplied by the Sydney Futures Exchange. There is significant evidence of structural changes in both the persistence of volatility shocks and simultaneous volume effects following the change to screen trading in this futures market.

Determinants of demand for Fiji's exports : an empirical investigation

Fiji is no exception to the rule that exports are an important source of growth and development. In this light, it is important to know the determinants of exports. However, there is no empirical study on Fiji's export demand. This paper uses the modern econometric techniques—in particular, the autoregressive distributed lag approach to cointegration—to investigate whether the standard export demand variables, viz., trading partner income, export price, and competitor price, have a long-run cointegration relationship with Fiji's real exports for the period 1970 to 1999. In addition, the long-run results are also estimated by using the dynamic ordinary least squares and the fully modified ordinary least squares. The empirical results indicate the existence of a cointegration relationship among the variables. The long-run foreign income, own-price, and cross-price elasticities are found to be 0.7 to 0.8, −1.3 to −1.5, and 2.1 to 2.2, respectively.

Directors' timing is too good

Research from Deakin University has shown that some directors have earned abnormal returns after selling shares in their own companies, leading one of the researchers, Harminder Singh, to argue that the Australian Securities and Investments Commission 'may want to pay closer scrutiny to the trading activities of directors of small and medium companies.

Media pressures and corporate disclosure of social responsibility performance : a case study of two global clothing and sports retail companies

This paper investigates the social and environmental disclosure practices of two large multi-national companies, specifically Nike and Hennes and Mauritz. Utilising a joint consideration of legitimacy theory and media agenda setting theory, we investigate the linkage between negative media attention, and positive corporate social and environmental disclosures. Our results generally support a view that for those issues attracting the greatest amount of negative media attention, corporations react by providing positive social and environmental disclosures. The results were particularly significant in relation to labour practices in developing countries – the issue attracting the greatest amount of negative media attention for the companies in question.

An examination of Australia's insider trading laws

Considers that the effective regulation of insider trading is desirable in order to maintain investor confidence in Australia's share markets. Although the current laws and the use of continuous disclosure provide a workable foundation, the thesis further considers the ways in which insider trading may be more effectively regulated and prosecuted in Australia.
