Although the solution to a linear programming problem is not necessarily unique, the theoretical and practical implications of multiple optima have not been thoroughly discussed by agricultural economists. Recently there have been calls for greater recognition, resolution and exploitation of...

Two recent papers in this Review (Vol 47, No.2, August 1979) set out to evaluate alternative forecasting techniques applied in the Australian beef market. The two papers: "Forecasting NSW Beef Production: An Evaluation of Alternative Techniques," by C. Gellatly, and "Comparing the Box-Jenkins...

Sufficient conditions for dominance of simply related prospects are developed for newly defined classes of limited-variation-in-risk-parameter utility functions. Necessary and sufficient conditions are given for classes of contant-risk-parameter utility functions. The latter include classes of...

Simple functions of random variables, such as sums, products, quotients and powers, arise in many applications in stochastic economics. It is sometimes convenient to determine the moments of such functions. Cases where this has been or can be done analytically are reviewed, and comments offered...

A class of restraints on proportions is observed to be relevant in many applications of linear programming, but problem formulation for these restraints has received little attention in the literature. An approach reported by Taylor [5] is summarized, and an alternative approach is outlined. The...

Bugs are an unavoidable aspect of mathematical programming (MP) modelling. In this paper we discuss the prevention and diagnosis of bugs in MP models. The topic is rarely addressed in the literature but is crucial to the success of modelling projects, especially for large models. We argue that...

The role of dynamic programming as a means of examining the allocation and pricing problems in the theory of the firm is considered in this paper. The production relationships and equilibrium conditions as specified by neoclassical theory and linear programming are stated and dynamic programming...
