GM vs. Non-GM: A Survival Analysis of U.S. Hybrid Seed Corn
We analyze the rate of survival of hybrid seed corn in the U.S. market between 2000 and 2007 and ind that product characteristics and market structures have signi icant impacts. The results suggest that survival rates depend on spillover effects of learning regarding genetically modi ied seeds and close substitute seeds and that hybrids planted in the Corn Belt survive longer in the market than...
متن کاملGM vs . Non - GM : A Survival Analysis of Hybrid Seed Corn in the US
We investigate the survival of new seeds in the US hybrid corn seed market between 2002 and 2007. Controlling geographic location, we find that product characteristics and market structure variables have significant impacts on the hazard of corn hybrids. The results also suggest spill-over effects of learning among close substitute seeds, and a spatial pattern of survival: seeds in the center r...
متن کاملAflatoxin synthesis in corn fields in Guanajuato, Mexico.
Aflatoxin contamination of corn is an important problem internationally, particularly in tropical and subtropical conditions that favor infection and synthesis by Aspergillus. Environmental conditions (drought) and agronomic practices i.e. N fertilization have been reported as favorable to aflatoxin synthesis in the field. This study was undertaken to investigate whether the contamination of co...
متن کاملA Comparison of the Effects of Three GM Corn Varieties on Mammalian Health
We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603, MON 810, MON 863), which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and MON 863 are ...
متن کاملEffects of the GM Controversy on Iowa Corn-Soybean Farmers' Acreage Allocation Decisions
Prior to the 2000 planting season, some industry obsemers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers t...
