A Cobb-Douglas stochastic frontier function is estimated for the cow-calf enterprises in the Texas Rolling Plains using Standardized Performance Analysis (SPA) data. We find that factors promoting higher herd productivity include machinery investment, pasture-quality improvement, and protein...

This paper considers the economic and environmental implications of regulating water and air nitrogen emissions under single and multi-environmental media policies in the U.S. hog industry. We examine tradeoffs from policies designed to correct an externality in one medium, when there are...

This study uses data from a 2001 survey of Great Plains farmers to explore the adoption, usage patterns, and perceived benefits of computers and the Internet. Adoption results suggest that exposure to the technology through college, outside employment, friends, and family is ultimately more...

The value, relevance, and efficacy of conducting and publishing research has been widely debated throughout the agricultural economics profession. On the one hand, some argue that the research process creates little value and directly competes with teaching/outreach output. On the other hand,...

Private R&D is a major source of innovation and productivity growth in agriculture worldwide. This paper examines trends and determinants of agricultural R&D in China. Results show that while the public sector monopolized agricultural research until recently, private agricultural R&D has grown...

This paper uses conditional quantile regression to analyze the effects of genetically modified (GM) seed technology and management on production risk in agriculture, with an application to the distribution of corn yield in Wisconsin. Using the certainty equivalent (CE) as a welfare measure, our...

The authors regret that the above paper contained an error in the calculation of the survey expansion weights (Lambert et al., 2014, p. 110). Using the notation of the paper, the expansion factor for the lth stratum was introduced as wl =agbh=ngh, where g indexes states and h indexes farm size...

This study investigates worker shares of the returns to scale and returns to technology adoption on U.S. hog farms. The wage analysis controls for a matching process by which workers are linked to farms of different sizes and technology uses. Using four surveys of employees on hog farms...

This article provides the history underlying the journal impact factor and weaknesses of this measure to evaluate journal quality. The Eigenfactor and Article Influence Scores are suggested as an improved way to compare research quality and impact across disciplines. The network analysis...

The objective of this study is to analyze the determinants of private agricultural R&D investment in the United States and the liaison between public and private R&D sectors. The empirical analysis employs U.S. agricultural data for the 1970-1996 period. The results show that federal R&D...
