Stochastic Price Modelling Of High Volatility, Mean-Reverting, Spike-Prone Commodities: The Australian Wholesale Electricity Market, Andrew C. Worthington, Helen Higgs

It is commonly known that wholesale spot electricity markets exhibit high price volatility, strong mean-reversion and frequent extreme price spikes. This paper employs a basic stochastic model, a mean-reverting model and a regime-switching model to capture these features in the Australian national electricity market (NEM), comprising the interconnected markets of New South Wales, Queensland, South Australia and Victoria. Daily spot prices from 1 January 1999 to 31 December 2004 are employed. The results show that the regimeswitching model outperforms the basic stochastic and mean-reverting models. Electricity prices are also found to exhibit stronger mean-reversion after a price spike than in ...

M-commerce, a growing sub-category of E-business, allows business to be done 'anywhere, anytime'. However security of wireless devices remains problematic. It is unclear whether protocols to alleviate security problems, such as wireless vulnerability assessments (WNVAs), are being used or are effective. The paper reports on a survey-based study of Australian computer security professionals' use of and opinions about two types of WNVA: wireless monitoring and penetration testing. An initially surprising finding was how little both types are used, despite the ease with which wireless networks can be attacked and the fact that penetration testing is fairly well understood. In the ...

This paper employs a Generalised Autoregressive Conditional Heteroskedasticity in Mean (GARCH-M) model to consider the effect of macroeconomic factors on Australian property returns over the period 1985 to 2002. Three direct (office, retail and industrial property) and two indirect (listed property trust and property stock) returns are included in the analysis, along with market returns, short, medium and long-term interest rates, expected and unexpected inflation, construction activity and industrial employment and production. In general, the macroeconomic factors examined are found to be significant risk factors in Australian commercial property returns. However, the results also indicate that forecast accuracy in these ...

This paper examines the source of price discovery in the Australian Dollar currency market. The time-varying relationship between changes in quotes posted by cash market dealers and changes in currency futures quotes is estimated. The cash market quotations identifY the eleven dealers posting the quotes, as well as geographical location of the dealers (Australia or overseas). Reported results show that price discovery originates in the cash market in any trading period. Amongst CUlTency dealers, the results imply that local desks are price leaders during Australian trading hours. Though some foreign desks do contribute to price discovery during the European and ...
