This paper models supply response in U.S. agriculture using disaggregated output data and tests statistically key assumptions traditionally maintained in agricultural supply studies. Following Vasavada and Chambers; Shumway; and Ball, we use U.S.-level data, 1948-1999 to estimate a multiproduct...

This paper starts with the basic premise that the conventional measures of productivity growth, which ignore joint production of good and bad outputs, are biased. We then construct an alternative productivity growth measure using activity analysis. An application to U.S. agriculture demonstrates...

This paper is an assessment of patterns of investment by farm households via an econometric model adapted from a land allocation approach of Holt (1999). This analysis will shed light on the importance of different classes of assets to farm household well-being, and show the reaction of farm...

Water quality has implications for the health of our ecosystem and the welfare of our population. Agriculture is one of the major contributors of non-point source pollution that contaminates our nation's water supplies. Understanding how farmers substitute manure for commercial fertilizers...

Recent trends in livestock concentration in major corn producing states suggest that increasing risk of water pollution from manure applications may be offsetting declines in risk of water pollution from chemical fertilizer. Analysis of data from ARMS surveys found that potential excess nitrogen...

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...

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 study contrasts the relationship between farm-size and adoption for two types of innovations, genetically engineered crops and precision farming, controlling for other factors. The analysis uses an extension of the McDonald and Moffit decomposition for the two-limit Tobit model.

This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity. The model is estimated using nationwide farm-level survey data for 2005. Regression analysis confirms that Bt...

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...
