This study investigates the extent to which predicted electricity spot prices from a statistical model, along with consensus forecasts issued by the Australian Financial Market Association (AFMA), provide unbiased price estimates of a forward contract price over a specified time to expiration....

Previous studies provide conflicting evidence on the time series properties of company financial ratios, claiming either that the components of ratios exhibit nonstationarity which is not eliminated by the ratio transformation, or that a unit root in the components may be rejected which implies...

This paper compares the short-term load performance of several forecasting models, including a new class of nonlinear models known as smooth transition periodic autoregressive (STPAR) models. A model building procedure is developed for the STPAR model, along with a linearity test against smooth...

This study develops a method to select variables, and to specify the relative importance of those variables, as input for failure models. In addition, our method provides estimates of the failure probabilities of organisations at a point in time. The results of tests of our method on Australian...

In this paper, it is shown how one can employ the wavelet analysis to reconstruct data based only on the subset of information that differentiates the two fundamentally related time series: spot and futures indices. Such an analysis allows researchers to focus on examining the relationship...

The use of financial ratios by analysts to compare the performance of firms from one accounting period to the next is of growing importance with continued European economic integration. Recent studies suggest that the individual component series of financial ratios exhibit nonstationarity which...
