Última An Analysis of McLean County, Illinois Farmers' Perceptions of Genetically Modified Crops AgEcon Chimmiri, Nagesh; Tudor, Kerry W.; Spaulding, Aslihan D.. McLean County, Illinois farmers were surveyed in order to explore and analyze their perceptions of genetically modified crops and their genetically modified cropping decisions. Questionnaires were mailed to 400 randomly selected farmers, and 156 were returned. The 134 respondents who reported that they planned to plant crops in 2003 were asked to provide information about gender, age, education, and number of tillable acres farmed. Respondents were also asked if they had previously planted genetically modified crops and if they planned to plant either genetically modified corn or genetically modified soybeans in 2003. Finally, respondents were presented with 40 statements that pertained to biotechnology and genetically modified crops, and they were asked...

Ano: 2005 URL: http://purl.umn.edu/19204 Consumer demands for organic and genetically modified foods AgEcon Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W.. Issues concerning consumer demands for genetically modified and organic food remain topical. It is unclear how consumers perceive issues associated with food production such as food safety, environmental impacts or animal welfare. It is also unclear how consumers might value potential changes in those issues in regional and metropolitan centres. This paper reports on research using the choice modelling technique to estimate and compare consumer demand for genetically modified and organic foods in Australia. The case study considers tomatoes, milk and beef commodities. The results draw comparisons between the contribution of associated factors influencing consumer purchasing decisions in a regional and metropolitan city. The results are relevant to the...

Ano: 2003 URL: http://purl.umn.edu/57862 Consumer Interest in Environmentally Beneficial Chicken Feeds: Comparing High Available Phosphorus Corn and Other Varieties AgEcon Pesek, John D., Jr.; Bernard, John C.; Gupta, Meeta. One source of phosphorous pollution in areas of high chicken production is runoff from fields using fertilizer from these operations. A potential solution is to feed chicken high available phosphorus (HAP) corn, reducing phosphorus in manure. This study examined consumer purchase likelihood of chickens fed HAP, created traditionally or through genetic modification, and other genetically modified (GM) corn including Bt and Roundup-ready. Survey results from the Delmarva Peninsula found considerable interest in non-GM HAP corn, although GM HAP corn was not typically viewed as more acceptable than other GM varieties. Overall, the marketplace appears open to products geared toward environmental benefits.

Ano: 2011 URL: http://purl.umn.edu/117945 Consumer Likelihood to Purchase Chickens with Novel Production Attributes AgEcon Bernard, John C.; Pesek, John D., Jr.; Pan, Xiqian. Typical supermarket chickens are produced with novel or controversial attributes. This continues despite contrasting growth in consumer interest in organic and natural foods. This study surveyed Delaware consumers’ likelihood to purchase chicken given different attributes: free range, given antibiotics, irradiated, fed genetically modified (GM) fee, GM chicken, and price. Examining conjoint analysis data with a heteroskedastic two-limit tobit model, GM chicken and other novel attributes were found to lower purchase likelihood significantly. Understanding these results should help the industry meet consumer preferences while aiding its continued expansion to benefit workers and growers across the South.

Ano: 2007 URL: http://purl.umn.edu/6058 CONSUMER VALUATION OF GENETICALLY MODIFIED FOODS AND THE EFFECT OF INFORMATION BIAS AgEcon Vanwechel, Tamara; Wachenheim, Cheryl J.; Schuck, Eric C.; Lambert, David K.. Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction. Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products. Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk. Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM. The influence of information bias on bids varied among selected participant groups, supporting the presence of uniquely...

Ano: 2003 URL: http://purl.umn.edu/23620 COOPERATIVE MARKETING IN SPECIALTY GRAINS AND IDENTITY PRESERVED GRAIN MARKETS AgEcon Janzen, Edward L.; Wilson, William W.. Marketing of specialty and identity preserved grains has become an important strategy in the grain marketing industry and is being driven, in part, by consumer and processor demand and an interest in non-GM products. This study provides background and practices of numerous organizations involved in marketing of specialty/identity preserved grains. Supporting marketing activities are reviewed. Key factors in the success (or failure) of their efforts are identified. Major challenges facing the participants in the specialty/IP grain marketing industry are discussed. The primary focus is on the role of agricultural cooperatives and producer owned alliances.

Ano: 2002 URL: http://purl.umn.edu/23558 COSTS AND RISKS OF CONFORMING TO EU TRACEABILITY REQUIREMENTS: THE CASE OF HARD RED SPRING WHEAT AgEcon Wilson, William W.; Henry, Xavier; Dahl, Bruce L.. Stochastic simulation was used to determine the marginal cost and optimal testing strategy (location and intensity) for an integrator conforming to proposed European Union traceability requirements for imported hard red spring wheat. Cost, risks and premiums were determined for exports of non-genetically modified (non-GM) wheat from the U.S. to the EU. Cost components include certified seed, certification and auditing, testing, traceability, quality loss, and a risk premium for the added risk of a dual traceability system over a single non-traceability system. The optimal strategy is the one that maximizes the integrator's utility (minimizes disutility of integrator's additional costs). Adventitious commingling is defined stochastically. Results...

Ano: 2005 URL: http://purl.umn.edu/23484 European Preferences for Beef Steak Attributes AgEcon Tonsor, Glynn T.; Schroeder, Ted C.; Fox, John A.; Biere, Arlo W.. A choice experiment is used to evaluate how consumers in London, Frankfurt, and Paris value beef steaks with attributes such as: "hormone-free," "GM-free," farm-specific source verification, and domestic origin. The effect of various consumer characteristics on steak selection is also evaluated. Results suggest that European consumers are significantly heterogeneous in their preferences for beef steak attributes. French and German consumers have a higher willingness to pay to avoid genetically modified feed use than British consumers, while German and British consumers would pay more for growth hormone-free beef. French and German consumers are willing to pay for farm-specific source verification.

Ano: 2005 URL: http://purl.umn.edu/31213 IMPACT OF IDENTITY PRESERVATION OF NON-GMO CROPS ON THE GRAIN MARKET SYSTEM AgEcon Vandeburg, Jennifer M.; Fulton, Joan R.; Dooley, Frank J.; Preckel, Paul V.. The impact of identity preservation (IP) for genetically modified grains (GMOs) on the grain handling system for a typical region in the Eastern Corn Belt is examined. A cost minimizing linear programming model of the transshipment system from farms to grain elevators to grain users tracks shipments and costs through the marketing system. This study compares two different grain segregation strategies: segregating grain within the elevator and designating specific elevators as IP-only facilities. As the cost per unit for grain segregation increases, the designated plant strategy becomes the most cost efficient strategy.

Ano: 2000 URL: http://purl.umn.edu/28627 Trait Stacking, Licensing, and Seed Firm Acquisitions on Genetically Modified Grains: A Strategic Analysis AgEcon Wilson, William W.; Huso, Scott R.. Commercialization of genetically modified (GM) traits leads to interesting strategic questions for agbiotechnology and seed firms. The purpose of the study is to evaluate equilibrium strategies of agbiotechnology and seed firms regarding commercialization of GM traits. Two game theory models were developed to examine equilibrium strategies. In the first, both agbiotechnology firms have commercialization strategies of licensing or not. In the second, the agbiotechnology firm also has the strategic option to purchase a seed form as a commercialization strategy. Results indicate that the equilibrium strategy would be for each of the agbiotechnology firms to license their traits, and the seed firm would release a stacked trait. However, order of play...

Ano: 2008 URL: http://purl.umn.edu/46560 WHEAT CHARACTERISTIC DEMAND AND IMPLICATIONS FOR DEVELOPMENT OF GENETICALLY MODIFIED GRAINS AgEcon Janzen, Edward L.; Mattson, Jeremy W.; Wilson, William W.. Agricultural biotechnology is advancing rapidly and is embracing all major crops. The adoption of genetically modified corn, soybeans, and cotton have reached high levels in the United States. Wheat is the next major crop confronting the biotechnology issue, but no commercial varieties of genetically modified (GM) wheat have been released yet. Primary opportunities for GM developments in wheat center around improvements that meet consumer and end-user needs/issues in addition to meeting producer efficiencies. Developers and proponents of GM wheat must focus on education of consumers and restoration of worldwide confidence in the regulatory systems. The most desired wheat quality trait among millers and bakers is the assurance of consistent quality.
