The hypothesis of this study is that there is a statistical relationship between the lung cancer mortality rate and the intensity of fuel consumption (measured in gallons/square mile) at a particular location. We estimate cross-section regressions of the mortality rate due to lung cancer against...

The hypothesis of this study is that there is a statistical relationship between the cardiovascular disease mortality rate and the intensity of fuel consumption (measured in gallons/square mile) at a particular location. We estimate cross-sectional regressions of the mortality rate due to...

Previous studies have found that organic crop production in the midwestern United States can be more profitable than conventional crop production. However, these studies have failed to consider potential differences in farm size between the two systems. If an organic crop rotation cannot be...

Anaerobic digesters for livestock operations are receiving attention for energy production and odor control. A farm-based digester went into operation in September 1999, on an 800-cow dairy farm in Minnesota. The goals of this paper are to analyze the contribution that a digester system can make...

The economics of applying swine manure is analyzed from the different perspectives of a producer and a custom manure applicator. The analysis shows that the fertilizer savings that result from lowering the application rate and covering more acres may cover the cost of the applicator investment....
