Agricultural Producers and the Environment: A Stated Preference Analysis of Colorado Corn Producers

摘要

This paper analyzes Colorado corn producers’ preferences over both private- and environmental public-good production system attributes, and tests the robustness of alternative data reconstruction and estimation techniques. Irrigated corn production practices are characterized by intensive water and chemical use, resulting in nonpoint source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations (and several alternative fixed parameter specifications) uncover consistently positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The analysis also finds evidence of preference heterogeneity and a complementary relationship between the two environmental attributes. Analysis of this kind can be used by policy makers to predict behavioral responses associated with introduction of new technologies, or to assess welfare implications of agricultural policy changes and stricter environmental regulations.
