German and British Consumer Willingness to Pay for Beef Labeled with Food Safety Attributes

Karen E. Lewis; Carola Grebitus; Gregory Colson; Wuyang Hu

The European Union has implemented some of the most stringent food safety policies for beef globally, ranging from banning growth hormones to mandating country of origin labeling. Using choice experiments and random parameter logit models, we examine German and British consumer willingness to pay (WTP) for American, Canadian, Argentinian, French, German and British beef, quality assurance seals, hormone-free beef production and a gourmet label. We also determine how consumer WTP for these food safety and quality attributes is affected by the extent to which consumers consider food safety issues (FSI). Results indicate that British consumers had the lowest WTP for beef from Argentina and German consumers had the lowest WTP for beef from Great Britain. The hormone-free label was the relatively most preferred label by consumers in both countries, and by those who considered FSI to affect their meat consumption patterns.

Why U.S. Consumers Support Country of Origin Labeling: Examining the Impact of Ethnocentrism and Food Safety

Karen E. Lewis; Carola Grebitus

ABSTRACT The legality of U.S. country of origin labeling (COOL) laws for agricultural products has been challenged by foreign countries. Isolating the reasons why consumers support COOL can help determine the efficiency of COOL as a policy. Therefore, this study investigated why consumers have a desire for COOL. Data were collected through an online survey with 566 U.S. participants. Results of a bivariate ordered probit model indicate that as consumers are more ethnocentric and more pessimistic about the safety of their food, they are more likely to support COOL for sugar and for sugar in soft drinks. Thus, policies designed to inform the public about the safety of foreign commodities could reduce their desire for COOL. Evidence is also provided that highly ethnocentric individuals support COOL in an effort to “buy American” products.

Tennessee Beef Producers' Willingness to Participate in a Tennessee Branded Beef Program

Elizabeth McLeod; Kimberly L. Jensen; Andrew P. Griffith; Karen E. Lewis

Tennessee cattle producer willingness to participate in a hypothetical Tennessee Branded Beef Program (TBBP) was examined using 2016 survey data. Willingness to participate in the TBBP was modeled using a probit model. Among those willing to participate, a Tobit model was used to estimate the pounds of live-weight beef producers were willing to supply into a TBBP. Age, production practices, and risk attitudes influenced willingness to participate. Among those willing to participate, projected TBBP supply per farm averaged 32,329 pounds and was influenced by on-farm animal units, production practices, perceived barriers, risk attitudes, and consequentiality beliefs.

Food Security through Biotechnology: The Case of Genetically Modified Sugar Beets in the United States

P. Lynn Kennedy; Karen E. Lewis; Andrew Schmitz

Abstract While genetically modified (GM) crops have provided tremendous agricultural productivity gains, many consumers oppose GM products and maintain they are unsafe. We use the case of GM sugar beets and their adoption by the US producers to examine the implications of GM technology on food security. A partial equilibrium framework is used to examine the implications of GM technology on food security. This analysis provides a unique opportunity to examine the impact of GM adoption in one product (sugar beets) relative to non-GM adoption in a substitute product (sugarcane). This analysis examines the potential gains to food security through the adoption of biotechnology versus consumer fear of GM technology. Research and development (R&D) has potential implications not only through its impact on supply, but also on demand as well. This study shows that demand impacts can negate the supply-induced food security gains of R&D. Regulations such as mandatory labeling requirements can impact this outcome.
