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...

The greenhouse sector has reinvented itself as a technologically advanced and relatively environmentally friendly industry over the past 15 years. However it remains a high energy user. Two recent surveys have highlighted the potential impact on greenhouse grower costs of the proposed emissions...

We used the well-being evaluation method, a technique for measuring individual utility, to study how people in the wildland urban interface of Colorado (USA) felt about their lives before and after two wildfire scenarios. Variables such as age, family size, fire frequency, and house value were...

We build our economic models and estimate grazing policy impacts based on the standard economic model of profit maximization. Yet, over 30 years of research and observation has shown that, for many, consumptive and quality of life values are the most important reasons for the purchase of western...

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...

Several agro-ecological practices have been developed to increase the range of soil fertility management options available to farmers, but little information is available on their labour input requirement and profitability relative to conventional practices. This study used a multiple visit...

The recent/current recession provides the opportunity to study the effects of the macroeconomic changes on the agricultural production systems in the Great Plains and trace some of its impacts through the system to changes in primary inputs such water resource use. Therefore, the objective of...

This paper presents a comparative analysis of three different economic studies that played major roles in the policy debate over the Compact. It draws an important distinction between before-after and counterfactual impact analysis and highlights constraining assumptions in models. Over time the...
