THE ECONOMICS OF ORGANIC FARMING IN THE U.S.: THE CASE OF TOMATO PRODUCTION AgEcon
Jans, Sharon; Fernandez-Cornejo, Jorge.
This paper presents an econometric estimate of the effect of adopting organic tomatoes on yields, revenues, and farm profits. The model accounts for self-selection, simultaneity, and is theoretically consistent. Data are obtained from USDA=s 1998 survey, which for the first time provides data on organic and conventional operations growing tomatoes.

Adoption of Agricultural Production Practices: Lessons Learned from the U.S. Department of Agriculture Area Studies Project AgEcon
Caswell, Margriet; Fuglie, Keith O.; Ingram, Cassandra; Jans, Sharon; Kascak, Catherine.
The U.S. Department of Agriculture Area Studies Project was designed to characterize the extent of adoption of nutrient, pest, soil, and water management practices and to assess the factors that affect adoption for a wide range of management strategies across different natural resource regions. The project entailed the administration of a detailed field-level survey to farmers in 12 watersheds in the Nation to gather data on agricultural practices, input use, and natural resource characteristics associated with farming activities. The data were analyzed by the Economic Research Service using a consistent methodological approach with the full set of data to study the constraints associated with the adoption of micronutrients, N-testing, split nitrogen...

FARM-LEVEL EFFECTS OF ADOPTING HERBICIDE-TOLERANT SOYBEANS IN THE U.S.A. AgEcon
Fernandez-Cornejo, Jorge; Klotz-Ingram, Cassandra; Jans, Sharon.
This paper estimates the on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization. The model is estimated using nationwide farm-level survey data for 1997. Given that the use of herbicide-tolerant soybeans involves the substitution of a particular herbicide - primarily glyphosate - for other herbicides, we explicitly consider this substitution process in the model.
Tipo: Journal Article Palavras-chave: Genetically engineered soybeans; Herbicide tolerance; Herbicide use; Farm profits; Technology adoption; Yields; Crop Production/Industries; Research and Development/Tech Change/Emerging Technologies.
