The objective of this study is to assess the scale and technical efficiencies and other economic performance measures of southeastern U.S. cow-calf farms. We describe and compare cow-calf operations by size and farm resource region and measure their relative competitiveness. We estimate an input...

Productive utilization of resources has enabled American agriculture to supply the nation with vast quantities of food at a high level of efficiency. However, the USDA shows that 2011 pesticide expenses increased by about $100 million resulting from a slight increase of planted acres and a...

This study describes and compares cow-calf operations and assesses their relative competitiveness, developing performance measures for a sample of U.S. farms. We find that larger operations tend to be significantly more scale and technically efficient than smaller operations. However, we do not...

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...

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...

Our initial findings indicate that GM crops do not contribute to the decline of traditional family farms. We make a significant methodological impact by using the within transformation to remove unobserved individual effects and demonstrate that the within transformation results in ML estimates...

We estimate an input distance function for U.S. dairy farming to examine the competitiveness of organic and non-organic dairy production by system and size. Across organic/non-organic systems and size classes, size is the major determinant of competitiveness based on various measures of...
