A Continuum of Consumer Attitudes Toward Genetically Modified Foods in the United States AgEcon
Ganiere, Pierre; Chern, Wen S.; Hahn, David E..
A national telephone survey was conducted in the United States in April 2002 to study the consumer acceptance of genetically modified (GM) foods. Attitudes toward GM foods were examined through the use of a multiple correspondence analysis (MCA), analyzing the interrelationships among many categorical variables. This method was combined with a cluster analysis to construct a typology of consumers' attitudes. Four distinct classes of attitudes were finally extracted, denoted as: Proponents, Non-Opponents, Moderate Opponents, and Extreme Opponents. It was estimated that only 35% of the surveyed population was opposed to GM foods.

An Experimental Investigation of Consumer Willingness to Pay for Non-GM Foods When an Organic Option Is Present AgEcon
Bernard, John C.; Zhang, Chao; Gifford, Katie.
This research compared bids that consumers placed on non genetically modified (GM), organic, and conventional versions of food products in order to determine if the organic market well serves those seeking to avoid GM foods. Auction experiments using potato chips, tortilla chips, and milk chocolate were conducted with 79 subjects. Bids were modeled as a function of consumer demographics using a heteroskedastic tobit regression model. Results with the non-GM attribute nested into the organic characteristic showed that the latter's marginal effects were insignificant. This suggested the potential to further develop non-GM products for consumers not willing to pay extra for the remaining organic attributes.

Consumer Willingness to Pay for Genetically Modified Food Labels in a Market with Diverse Information: Evidence from Experimental Auctions AgEcon
Huffman, Wallace E.; Shogren, Jason F.; Rousu, Matthew C.; Tegene, Abebayehu.
With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important...

Consumers’ Willingness to Pay for New Genetically Modified Food Products: Evidence from Experimental Auctions of Intragenic and Transgenic Foods AgEcon
Colson, Gregory; Huffman, Wallace E..
Early GM traits were obtained by transferring genes across species, largely from soil bacteria. Part of the consumer resistance to them has been their transgenic nature. Recently, breakthroughs have occurred using intragenic bioengineering where genes are moved long distances within a specie, for example in potato, and without antibiotic markers. The objective of this research is to assess consumers’ acceptance and willingness to pay (WTP) for new intragenic fresh potato, tomato, and broccoli with higher levels of antioxidants and vitamin C, which are consumer traits. To elicit consumer valuations, a new series of experimental auctions were conducted in 2007 that built upon methodology developed in our earlier research. WTP was assessed in a multi-round...

Effect of the Information on the Intention of GM Food Consumption AgEcon
Martinez-Poveda, Africa; Molla-Bauza, Margarita Brugarolas; Martinez, Laura Martinez-Carrasco; Gomis, Francisco Jose Del Campo.
This work is focused on the study of consumption acceptance towards GM foods, analysing the level of knowledge and perceptions about them. Conjoint Analyses will be used to determine the importance of different attributes on purchase intention and GM food consumption intention will be measured as well as the effect of information on consumption intention.

Genetically Modified Crops: Risks and Promise Ecology and Society
Conway, Gordon; The Rockefeller Foundation; president@rockfound.org.
GM foods have the potential to provide significant benefits for developing countries. Over 800 million people are chronically undernourished, and 180 million children are severely underweight for their age. By 2020, there will be an extra two billion mouths to feed. Ecological approaches that underpin sustainable agriculture (e.g., integrated pest management) and participatory approaches that strengthen farmers' own experimentation and decision making are key. Biotechnology will be an essential partner, if yield ceilings are to be raised, if crops are to be grown without excessive reliance on pesticides, and if farmers on less favored lands are to be provided with crops that are resistant to drought and salinity, and that can use nitrogen and other...

GM FOOD LABELING POLICIES OF THE U.S. AND ITS TRADING PARTNERS AgEcon
Rousu, Matthew C.; Huffman, Wallace E..
Much of the international controversy of GM foods is due to labeling policies. Countries around the world have chosen different policies to label GM foods. We examine the labeling policies of several areas: the United States, the European Union, Australia, Japan, Canada, and China. We discuss each country's GM labeling policy, along with a brief history of how each country arrived at their current policy. We conclude by discussing how different policies are due to different ethical concerns of GM foods, along with the difference in perceived risks GM foods pose to health, the environment, and trade.

Labelling Issues of Organic and GM Foods in Australia AgEcon
Chang, Hui-Shung (Christie).
Growth in the demand for organic foods has been phenomenal in the past decade both in Australia and overseas because organic production is seen to be beneficial to both human health and the environment. In general, organic products commend a price premium over conventional products. Since organic attributes cannot be verified easily and there is no control over the use of the word 'organic' in the Australian market, the organic label has been subject to abuse. Over ten years, the Australian organic industry has called for a domestic regulation, claiming that any incidence of consumer deception and product misrepresentation can result in the loss of consumer confidence and sales, and more importantly, hinder future industry growth. However, the...

Spanish Consumers' Attitudes and Acceptability towards GM Food Products AgEcon
Angulo, Ana Maria; Gil, Jose Maria.
The objective of this paper is to analyse consumers’ attitudes and acceptability of GM food products in Spain. From the methodological point of view, a three-equation model of consumer behaviour is estimated assuming a kind of causal chain among the degree of knowledge, attitudes and buying intentions. Explanatory variables include socioeconomic characteristics of respondents as well as endogenous variables of the previous equations. The model provides a better knowledge of how attitudes and buying intentions towards GM food are formed. Higher educated consumers, more concerned about labelling information and less about price, and regular buyers of organic foods show a higher (not necessarily better) knowledge on GM technology and its consequences....
