An Economic Comparison of Sheep Grazing Systems on the Northern Tablelands of NSW AgEcon
Scott, J. Fiona.
Three 54ha "farmlets" were established in 2000 near Uralla, NSW to trial high input, moderate input and intensive rotational grazing systems. A representative farm approach was used to interpret the profitability results of the trial from July 2000 to June 2005 at a commercial scale level to make research results more relevant to farmers. At the gross margin level, the high input farmlet had the highest annual gross margins, but this farmlet had the worst whole farm performance. These contrasting results support the claim that annual activity gross margins cannot alone indicate the profitability of an investment. This demonstrates that whole farm analysis is the most suitable method to assess different grazing systems.

Profit and Variance Analysis of Cotton Production Technologies and Rotation Crops in Georgia AgEcon
Flanders, Archie; White, Fred C.; Shurley, W. Donald; Brown, Steve M..
Genetically modified cotton varieties have the potential for increasing returns and/or decreasing labor requirements. A nonlinear optimization model is applied to a whole farm analysis for evaluating cotton production technologies. This model maximizes farm utility, composed of expected returns and their variability, at various risk aversion levels in order to evaluate cotton production technologies. Results show that while conventional cotton maximizes utility in a risk-neutral situation, transgenic cotton varieties entered into the optimal solutions as higher levels of risk aversion were considered.
