This paper uses variance decomposition modelling to explore how wheat revenuevolatility in Australia has changed spatially and temporally. The components ofrevenue variance are the variances and covariances of wheat prices, the area of wheatharvested and the yield of wheat. The key finding is...

Using stochastic frontier analysis, efficiency of production of wheat in WesternAustralia was studied. The production function model used was a relatively simpleinput model, consisting of wheat yield, effective rainfall, fertilizer application rates andyear of study. Inefficiency was captured in...
