Policies to mitigate greenhouse gas emissions are likely to increase the prices for fossil fuel based energy. Higher energy prices would raise farmers' expenditure on machinery fuels, irrigation water, farm chemicals, and grain drying. To compute the economic net impacts of increased farm input...

A multiperiod regional mathematical programming model is used to evaluate the potential economic impacts of global climatic change on the southern U.S. forestry sector. Scenarios for forest biological response to climate change are developed for small and large changes in forest growth rates....

We examine the economic tradeoff between the costs of pre-event preparedness and post-event response to the potential introduction of an infectious animal disease. In a simplified case study setting, we examine the conditions for optimality of an enhanced pre-event detection system considering...

Agriculture operates in an uncertain environment. Yields, prices, and resource usage can change dramatically from year to year. However, most analyses of the agricultural sector, at least those using mathematical programming methods, assume decision making is based on average yields, ignoring...

Mathematical programming formulations can yield faulty answers. Models can be unbounded, infeasible, or optimal with unrealistic answers. This article presents techniques for theory-based discovery of the cause of faulty models. The approaches are demonstrated in the context of linear...

In an effort to bolster confidence and protect the nation the U.S. government through agencies like the Department of Homeland Security is identifying vulnerabilities and evolving strategies for protection. Agricultural food supply is one identified vulnerable area, and animal disease defense is...

Mathematical programming is one technique that can be used for resource policy appraisal. Multiple objectives are usually involved in resource policy considerations. This paper discusses issues regarding the use of mathematical programming techniques for the multiobjective resource policy arena....

Model validation is a topic which has a long history in the literature This article attempts to focus much of the previous discussion upon agricultural economics models. True model validation is not possible. Nevertheless, model validation exercises improve the relevancy of models and strengthen...
