      abstract = {Single-index models from portfolio theory have previously  been adapted for risk efficient farm planning in North  America. The potential for using single-index models in  farm planning is considered in this paper both  theoretically and in the light of two illustrative  Australian case studies. It is concluded that single-index  models have no significant computational or other  advantages over full quadratic programming portfolio  selection models for farm planning and may produce  relatively poor plans and poor assessments of the risks  associated with those plans.},
