To evaluate the impact of conservation policies on soil organic carbon in agricultural soils, the authors link information from the 1992 National Resources Inventory (NRI) database and the extensive physical data on soils and climate from the SOILS5 database. These data serve as input for a...

The problem of targeting CRP purchases to buy environmental amenities under productivity and environmental heterogeneity is considered. Gini coefficients and Lorenz curves are used to measure the effectiveness of spending under alternative targeting criteria. The environmental benefits...

We compare subsidies and fines to voluntary and mandatory refuge insurance (insurance for pest damage on Bt corn refuge) as mechanisms for securing grower compliance with EPA refuge mandates. A conceptual model partially ranks mechanisms. We empirically quantify tradeoffs between mechanisms...

The policies restricting the use of atrazine and other triazines to achieve desirable water quality standards are analyzed in a CEEPES framework. Five policies, including atrazine post restriction, restricting atrazine to meet MCL and HAL standards in runoff, a complete ban on atrazine, and also...

The Central Nebraska Basin (CNB) is the site of intensive agricultural activity, in part because of the good irrigation supplies provided by the Middle Platte alluvial aquifer system. In this paper, the authors describe the integrated modeling system that addresses the economic and environmental...
