Progress 10/01/05 to 09/30/10
Outputs OUTPUTS: A number of activities were undertaken. One research study used mail surveys to study consumer preferences for type and amount of fat in ground beef. Another study focused on studying consumers' food values, which are overarching constructs explaining food choice. Economic experiments were conducted in grocery stores to study consumer preferences for organic food and grass-fed beef. Several studies, including telephone and mail surveys and economic experiments, studied consumer preferences for farm animal welfare, a topic gaining in importance as several states have recently passed ballot initiatives banning certain agricultural practices. Economic experiments and surveys were also conducted to determine the extent to which altruism and inequality aversion can explain people's preferences for certain food products and farm policies. Other studies have focused on estimating the value of new genetic testing technologies in beef. Finally, several studies were aimed at investigate and improving methods for eliciting consumer's values for use in marketing and cost-benefit analysis. Several events were involved with the project. In March 2006, Lusk organized a conference titled "Guiding Food and Agricultural Marketing Policy in the Face of Changing Market Structures" in Washington, D.C. Lusk has also helped organize dozes of symposiums related to consumer and agribusiness decision making the professional meetings of the Agricultural and applied Economics Association, Western Agricultural economics Association, and the Southern Agricultural Economics Association. Lusk has also given numerous invited talks on the research findings at Universities, professional academic conferences, agricultural industry meetings, and to those working in government positions. Many services have been offered from the project. Lusk teaches a graduate level course, where he trains students on them the methods used to study consumer decision making. Lusk also wrote an academic book on research methods to improve consumer and agribusiness decision making. Finally, Lusk has served as an official and unofficial consultant on many projects for agribusinesses and government agencies. Products from the project include numerous journal articles, several books, and the creation of decision aids. Examples of one decision aid, which provides market-share simulations for firms considering the introduction of meat or milk from cloned animals, can be found at http://agecon.okstate.edu/faculty/publications/3103.xls or http://agecon.okstate.edu/faculty/publications/3104.xls. Results of the research have been disseminated in popular press articles, academic journal articles, books, and via numerous presentations. PARTICIPANTS: The research included numerous collaborators, including agricultural economics faculty and students at Oklahoma State University (e.g., Bailey Norwood, Shida Henneberry, Kate Brooks), economics and agricultural economics faculty at other U.S. Universities (e.g., Ken Foster at Purdue, Ted Schroeder at Kansas State, Keith Coble at Mississippi State, John List at University of Chicago, Jason Shogren at University of Wyoming), government employees (e.g., Laurian Unnevehr at the USDA Economic Research Service), faculty outside the U.S. (e.g., Jutta Roosen at Technical University of Munich in Germany; Stephan Marette at INRA in France; Ellen Goddard at the University of Alberta in Canada; Jae Bong Chang at the Korean Rural Development Institute in Korea), non-economists (e.g., Bob Weaber in Animal Science at University of Missouri; Melissa Moore in Marketing at Mississippi State University; Sara Jeager in sensory science in New Zealand), and individuals working in agribusinesses and industry organizations (e.g., National Cattlemen's Beef Association, National Soybean Board, the National Pork Board, Pfizer, Merial). TARGET AUDIENCES: Research publications and seminars were targeted at a number of groups. First, were individuals involved in formulation of policy at the USDA, FDA, and EPA. Second were agricultural producer organizations such as National Cattlemen's Beef Association, National Soybean Board, the National Pork Board. Third were agribusinesses. Finally, some of the work was aimed at educating the food consumer about modern agricultural production practices. PROJECT MODIFICATIONS: There were no project modifications
Impacts The research on consumer preferences for animal welfare was used heavily by agricultural organizations and by organizations advocating for enhanced animal welfare. Both the Farm Bureau and the Humane Society of the United States used the results from the research studies to craft press releases, formulate policy, and craft public relations messages. Research on consumer preferences for new technologies such as genetically modified food, antibiotics, organics, and cloning have been used by government agencies to inform cost/benefit analysis of proposed regulations, and have helped agribusinesses in marketing and product adoption decisions. The results have also been used to help craft educational and promotional materials. Research on the value of new genetic testing technologies in cattle has also had an impact. Lusk has made several important contributions in the area of livestock marketing. The work helped cattle producers and feedlots judge the merits of new technology currently being marketed by several animal genetics companies. The models developed by Lusk to determine the value of genetic information to optimally sort cattle have been used by a number of the largest feedlots in the U.S. and were used by several genetic testing companies in their marketing efforts. Finally, the research on methods of studying consumer preferences has had a significant impact on the agricultural economics profession. The profession now increasing uses methods that have been shown to produce better and more accurate depictions of consumer preferences, and these changes have led to better decisions by agribusinesses and policy makers.

Progress 10/01/08 to 09/30/09
Outputs OUTPUTS: A number of studies are underway examining consumer and agribusiness decision making in both Oklahoma and the United States. First, research on consumer preferences for farm animal has continued and a book on the topic to be published by Oxford University Press is nearing completion. Second, several papers and projects are underway to investigate how people's preferences for farm policies and different foods relate to preferences for different types of farms and aversion to inequality. Third, several large-scale surveys were conducted to determine consumer preferences for use of cloning in livestock and to project the market impacts of the introduction of meat and milk from clones. Finally, several projects are underway to investigate and improve methods for eliciting consumer's values. Several papers have been written on this issue and additional data is being collected. PARTICIPANTS: Not relevant to this project. TARGET AUDIENCES: Not relevant to this project. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts In recent years a pronounced trend has developed toward a more demand driven marketplace where agricultural producers must give considerable thought into consumer demand for specific food and fiber attributes prior to making production decisions. More research is needed to assist agricultural producers and agribusinesses in determining potential profitability of selling new goods and in responding to new and uncertain events such as a policy or animal disease. The primary purpose of this research is to determine the reaction of consumers and producers to and the social welfare effects of a) the introduction of new products, b) new food and agricultural policies, and c) agricultural events.

Outputs A number of studies are underway examining consumer and agribusiness decision making in both Oklahoma and the United States. One research study was just completed studying consumer preferences for a ban on antibiotic use in pork production; findings from this study were published in three peer-reviewed journals. Another study utilized a mail survey to investigate the effects of government policies on people's preferences for genetically modified food. This work is in submission at a peer-reviewed journal. Several projects are underway to investigate and improve methods for eliciting consumer's values. One project aims to investigate the validity of an incentive compatible conjoint ranking mechanisms. Another project aims to investigate the validity of what we refer to as prediction-based non-market valuation. Data has been collected for both projects and results are being analyzed and written up.
