Informed debate on agricultural nonpoint pollution requires evaluation of regional water quality in relation to management practices. It is prohibitive, in terms of cost and time, to run the site-specific process models for regional policy analysis. Therefore, a simplified and robust...

Informed debate on agricultural nonpoint pollution requires evaluation of regional water quality in relation to management practices. It is prohibitive, in terms of cost and time, to run the site-specific process models for regional policy analysis. Therefore, a simplified and robust...

This paper discusses the rose of information structure (i.e., information cost, reliability, and distribution among agents) in the design of a regulatory mechanism for controlling non-point source pollution. An ambient concentration tax mechanism is examined for non-point source pollution with...

Analysis of alternative environmental policies often requires execution of computer simulation models of the ecological or economic phenomena involved. This paper explores efficiencies to be gained by using these simulation models in a program of constructing metamodels. Constructing a metamodel...

This paper presents a novel approach for generating information for regulatory and policy analysis, based on farmers' adoption of weed control technology. A simulation model, WISH, is used to generate cost and risk information on 258 weed control strategies. The environmental policies simulated...

Atrazine is the most widely used herbicide for corn and sorghum and the most commonly encountered in surface water and groundwater. In addition to water quality problems, atrazine poses hazards through atmospheric transport, food residues, and exposure of applicators and wildlife. It atrazine...
