This study integrates economic and physical models to estimate the social costs of several commonly suggested policies (chemical-use tax and three types of conservation payments) for reducing nitrogen loads to the Mississippi River and for controlling hypoxia in the Gulf of Mexico. The economic...

This nation-scale, watershed-level analysis focuses on the major trends and the spatial pattern of land use and the impact on watershed health. We estimate a simultaneous equation system to analyze the impact of land use on aquatic health in watersheds across the United States.

A leading cause of biodiversity decline is the habitat destruction associated with urban development. We use a database of county-level land use regulations to analyze the effects of local land use regulations on land use changes. We use the results of this analysis and a species-habitat...
