Presents a study which looked at farmers' choice of conservation, tillage, rotation and soil testing practices in the Nebraska corn area. Estimation of various combinations of the practices impact on fertilizer use, corn yield, and soil erosion; Details on a polychotomous-choice selectivity...

The growth in federal conservation programs has created a need for policy modeling frameworks capable of measuring micro-level behavioral responses and macro-level landscape changes. This paper presents an empirical model that predicts crop choices, crop rotations, and conservation tillage...

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...

Resource purchasing funds have become a major tool for environmental protection and resource conservation. These funds use various strategies to target resources for conservation, the choice of which may lead to striking differences in environmental performance. This paper develops an analytical...
