Última CONSUMERS' VALUATION OF DISEASE-RESISTANT NURSERY STOCK: A CASE STUDY OF DOGWOODS AgEcon Gardner, Justin G.; Eastwood, David B.; Brooker, John R.; Klingeman, William E.. This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death. Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with...

Ano: 2003 URL: http://purl.umn.edu/14676 Genetically Modified Crops, an Input Distance Function Approach AgEcon Gardner, Justin G.; Nehring, Richard F.; Nelson, Carl H.. 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 that are identical to OLS estimates.

Ano: 2008 URL: http://purl.umn.edu/6800 Genetically Modified Crops and Labor Savings in US Crop Production AgEcon Gardner, Justin G.; Nelson, Carl H.. In spite of widespread adoption there is mixed evidence as to whether or not adopting Genetically Modified (GM) crops increase farm welfare. One possible reason for widespread adoption is labor savings. Using a treatment effect model we estimate the labor savings associated with adopting a GM crop.

Ano: 2007 URL: http://purl.umn.edu/34919 The Killer Course Hypothesis AgEcon Gardner, Justin G.. Due to recent legislative changes, universities in Tennessee will receive funding based on student retention and graduation rates rather than enrollment. In light of these changes it is important that academics in all disciplines study retention rates in order to identify areas for improvement. I investigate the impact of “killer courses” on student retention both in the school of agriculture and in the general student population. In addition I explore alternative frameworks for addressing retention issues.
