IMPACTS OF THE ADOPTION OF GENETICALLY ENGINEERED CROPS ON FARM FINANCIAL PERFORMANCE
Provedor de dados: 31
Autores: McBride,   William D.; El-Osta,   Hisham S.
The rapid adoption of genetically engineered (GE) crops by U.S. farmers suggests that these technologies have been perceived to improve farm financial performance.  This study develops and applies an econometric model to data from corn and soybean producers in order to evaluate the financial impacts of the adoption of GE crops.  Results indicate that the adoption of GE crops has had a limited impact on financial performance that varies by crop, type of technology, type of farm, and region of the nation.  Factors other than the financial impacts appear to be important reasons for the rapid adoption of GE crops.

Conservation Tillage, Pesticide Use, and Biotech Crops in the U.S.A.
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Hallahan,   Charles B.; Nehring,   Richard F.; Wechsler,   Seth James; Grube,   Arthur.
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 using a panel data set.  This paper presents preliminary results for soybeans.

Parables: applied economics literature about the impact of genetically engineered crop varieties in developing economies
Provedor de dados: 31
Autores: Smale,   Melinda; Zambrano,   Patricia; Falck-Zepeda,   Jose Benjamin; Gruere,   Guillaume P.
A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them, consumer attitudes toward GE products, and implications for international trade. This paper focuses only on the applied economics literature about the impact of transgenic crop varieties in non-industrialized agricultural systems, with an emphasis on methods. A number of studies have surveyed the findings for both industrialized and non-industrialized agriculture,...

A Genetically Engineered Crop's Impact on Pesticide Use: A Revealed-Preference Index Approach
Provedor de dados: 31
Autores: Sydorovych,   Olha; Marra,   Michele C.
A revealed-preference-based method is proposed for assessment of the environmental and human health impact of genetically engineered (GE) crops.  This method employs the relative pesticide toxicity information from farmers' pesticide choices combined with volume of pesticides as an alternative to previous methods which are based on volume only, on number of pesticide applications, or on stated preferences.  The method is applied to estimate the changes in the impact of herbicides after environmental and health perspective.  The results indicate that, on average, a reduction in herbicide human heath and environmental impacts occurs when farmers adopt RR soybean varieties.
