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...

This study was based on the hypothesis that lenders to the rural sector have the potential to affect the rate of agricultural adjustment directly via capital formation. Multi-period linear programming models were developed to quantify the effects of lender policy on farm growth for wheat...

Methods of obtaining a utility maximizing solution from quadratic programming models for farm planning are presented. The methods require only simple modifications to models constructed to produce an EV frontier from a portfolio selection model.

This paper reviews the literature on the optimal replacement of capital equipment, especially farm machinery. It also considers the influence of taxation and capital rationing on replacement decisions. It concludes that special taxation provisions such as accelerated depreciation and investment...

Survey information in most countries shows very clearly that farmers achieve a wide range of profitability levels. Some of the variation will be due to farmers having different goals and objectives, but a significant proportion will also be due to variations in managerial skill. If even modest...

Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature,...
