| This paper investigates the key decision parameters of farmers related to the allocation of land between wheat production and pasture for sheep (wool) production. Wheat area supply response, is estimated across the Australian wheat-sheep zone using data for the period 1991 to 2004. Statistical results reveal that wheat growers in Western Australia are more price responsive than growers in the eastern states. Area adjustment is not significantly different between the regions. Rainfall has a positive influence on wheat production while time-related exogenous factors such as technical progress seemed to have little influence on the wheat yield over this period. |

| Using stochastic frontier analysis, efficiency of production of wheat in Western Australia was studied. The production function model used was a relatively simple input model, consisting of wheat yield, effective rainfall, fertilizer application rates and year of study. Inefficiency was captured in a second model that incorporated machinery capital investment, opening equity level, and year of study. Data covered the production years 2004 through to 2007. The results demonstrated that inefficiency was present in wheat production in Western Australia and that inefficiency increased over the period from 18% in 2004 to 29% in 2007. Higher machinery investment per hectare and opening equity levels reduced inefficiency, due to producers having sufficient... |

| This paper uses variance decomposition modelling to explore how wheat revenue volatility in Australia has changed spatially and temporally. The components of revenue variance are the variances and covariances of wheat prices, the area of wheat harvested and the yield of wheat. The key finding is that the volatility of wheat revenue (detrended) has more than doubled in every main wheat-growing State in Australia over the last 15 years or so Changes in wheat areas are mostly a minor source of revenue variance. The principal cause of volatility is yield changes with price changes increasing slightly in absolute importance when compared to their adjacent previous period. Greater downside yield risk is often the principal cause of the increased yield variance.... |
