A changing world of increasing complexity, fluctuating prices, high energy costs and limited data necessitate creative blending of economic theory and available empirical statistics to understand the welfare impacts in a specific market. In this paper, a programming approach is used in tandem...

Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in...

This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient...

In processing industries, plant location decisions are costly and have consequences for firm profitability. When raw materials are heavy or perishable, transportation costs limit shipping distances and processors must compete locally for raw material inputs. To determine the likely profitability...

This paper determines the dynamic interaction between prices of corn, soybean, grain sorghum (milo), wheat, feeder cattle and live (fed) cattle by taking into account the surge in corn consumption stemming from the boost of mandated ethanol production. Corn is a major carbohydrate-feed component...
