Klieve and MacAulay (1993) (KM) analyse bargaining between the Australian and Japanese Southern Bluefin Tuna (SBT) industries using game theory. The KM model is a Nash equilibrium with symmetrical information, threat functions and a set of biological constraints. When we attempted to include the...

In this paper a description is provided of the development and use of a target-MOTAD model for use in consultative work with farmers who are under financial pressure. The analysis of downside risk and introduction of a trade-off between financial and business risks are key features of this model...

This paper points out some difficulties in the econometric estimation of the original paper and suggests procedures for overcoming these.

In the past China has been self-sufficient in beef products, but, with a dramatic increase in consumer spending on food, demand for beef, which is seen as a novel and nutritious food, has grown. By employing a partial equilibrium model and sensitivity analysis under different scenarios, this...

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...

Simulation models are valuable tools in the analysis of complex, highly constrained economic systems unsuitable for solution by mathematical programming. However, model size may hamper the efforts of practitioners to efficiently identify the most valuable configurations. This paper investigates...

The parameter values and assumptions of any economic model are subject to change and error. Sensitivity analysis (SA), broadly defined, is the investigation of these potential changes and errors and their impacts on conclusions to be drawn from the model. There is a very large literature on...

Compared to studies evaluating the benefits from agricultural research, there are relatively few empirical studies of the net economic benefits of agricultural extension, and even fewer that consider both public and private sector extension effort. In this study we examine regional differences...

Batterham (1987) described a computer program which eases entry of mathematical programming data. Users of the program first use a text editor to enter data in a relatively efficient format, which the program then converts into MPS format as required by most mathematical programming solution...
