This paper outlines the traditional uses of input-output (I/O) modeling in watershed programs planned under federal "Principles and Guidelines." Generally, the national economic development costs and benefits are analyzed, and the I/O model is used to track on regional economic development...

This paper further tests dual interest theory and the metaeconomics approach to environmental choice, recognizing a possible role for empathy-sympathy (the basis for an internalized, shared other-interest) in tempering and conditioning the more fundamental tendency to pursue self-interest. To...

Optimal recycling of minerals can be thought of as an integral part of the theory of the mine. In this paper, we consider the role that wastewater recycling plays in the optimal extraction of groundwater, a renewable resource. We develop a two-sector dynamic optimization model to solve for the...

The following hypothesis was tested: Willingness to bear a negative water impairment externality differs between those who do and those who do not receive economic benefit from the impairment source, e.g., a paper mill. The hypothesis was tested using a hedonic analysis of ambient water quality...

This paper uses an economic catchment model to assess changes in land use, enterprise distribution, greenhouse gas emissions and nutrient loading levels from a series of policies that introduce carbon prices or nutrient reduction caps on land-based production in the Hurunui Catchment in...

Extant point-nonpoint trading programs involve trades of relatively certain point source emissions reductions for highly uncertain estimates of nonpoint reductions. Trade ratios, or uncertainty ratios, define the rate at which these imperfect substitute commodities are traded. Economic research...

Non-point source pollution and its impact on water quality are of great importance to policy makers, residence and farmers. This paper uses a hedonic property value model to investigate the marginal implicit values of water quality change in Hoover Reservoir in the Upper Big Walnut Creek (UBWC)...

In this research, we propose a framework to connect SWAT model with a dynamic discrete choice based land use model. With the recent years of cropland data layers published by NASS, USDA and data complied from other sources, we apply this framework to land use change in Upper-Mississippi River...

Agricultural production can degrade water sources through leaching of nitrogen and phosphorus from agricultural land to surface and ground water sources. To minimize the pollution from agricultural production, the U.S. Department of Agriculture promotes adoption of conservation practices....
