This paper examines the effect of off-farm work on the economic performance of corn farms. It estimates returns to scale and technical efficiency following an input distance function approach and compares the relative performance of corn farm operator households with and without off-farm work....

This paper examines the hypothesis that farmers may be adopting herbicide-tolerant crops because of the simplicity and flexibility of weed control, freeing management time. We develop an econometric model to analyze the adoption of HT soybeans controlling for the effect of off-farm work and...

While the growing importance of off-farm earnings suggests large benefits accrue to farmers from efforts to expand off-farm income opportunities, survival still depends on greater efficiency. To comprehensively gauge the economic health of farm operator households we interpret off-farm income as...

This study estimates farm-level effects of adopting 1997 herbicide-tolerant soybeans, Bt cotton, and herbicide-tolerant cotton and compares results obtained from various data sources. While adopters' yields are generally higher and pest control costs lower than those of nonadopters, considerable...

This paper presents the first part of an ongoing project whose objective is to present a long term relationship between conservation tillage, adoption of GE crops and pesticide use for major crops in the United States. In addition, the project aims to provide some innovative tests on causality...

This paper presents findings on the use of HT corn and quality-adjusted herbicide use for 12 key corn producing states using a panel data set for 1986-2008. Our preliminary findings indicate an insignificant impact of HT corn on herbicide use, conditioning or accounting for HT corn with other...

A notable feature of the adoption of genetically engineered (GE) corn is the rapid growth in seed prices accompanied by rapid increases in GE corn with multiple (stacked) traits, which have often seen to offer several advantages to farmers, particularly increased yields. This paper presents...

This study presents recent results on the impact of adopting Bt corn on farm profits, yields, and seed and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity and uses farm-level survey data for 2010. Results confirm previous findings that Bt...

This paper examines how off-farm work affects the economic performance of crop and (selected) livestock farms. It estimates returns to scale and technical efficiency following an input distance function approach and compares the relative performance of dairy and corn farm operator households...

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...
