Consumer Acceptance of Genetically Modified Food Products in the Developing World AgEcon
Curtis, Kynda R.; Wahl, Thomas I.; McCluskey, Jill J..
World-wide consumer response toward food products made from genetically modified ingredients has been largely negative. However, the majority of the previous studies on consumer attitudes towards genetically modified food products were conducted in developed countries in Europe as well as Japan. The small number of studies conducted in developing countries obtained different results from the developed world. This paper considers the motivations for consumer attitudes towards genetically modified foods in developing countries. We conclude that the generally positive perception towards genetically modified foods in developing countries could be the result of a cost-benefit analysis consistent with expected utility theory. Developing countries have more...

CONSUMER DEMAND FOR MANDATORY LABELING OF BEEF FROM CATTLE ADMINISTERED GROWTH HORMONES OR FED GENETICALLY MODIFIED CORN AgEcon
Lusk, Jayson L.; Fox, John A..
This study estimates the value of policies that would mandate labeling of beef from cattle produced with growth hormones or fed genetically modified corn. At no cost, 85 percent of resondents desired mandatory labeling of beef produced with growth hormones and 64 percent of respondents preferred mandatory labeling of beef fed genetically modified corn. Estimates suggest that consumers would be willing to pay 17.0 percent and 10.6 percent higher prices for beef on average to obtain information provided via mandatory labeling about whether the beef is from cattle produced with growth hormones or fed genetically modified corn, respectively.

Food biotechnology and education Electron. J. Biotechnol.
Ramón,Daniel; Diamante,Alicia; Calvo,María Dolores.
It is clear that the future of our children will be marked by the development of two scientific disciplines: computing and biotechnology. Regarding the first, during recent years considerable progress have been done in many countries around the globe aimed at enhancing the teaching in these subjects and, at the same time, encouraging the use of computers in classrooms. On the contrary, training in biotechnology is absent in many secondary schools of the planet. This formative deficiency generates citizens whose opinion on the marketing of biotechnological products is easily manipulated by both defenders and opposers of biotechnology. This situation is of particular relevance when the item in question is food biotechnological applications that provoke an...

GMOs: Prospects for Increased Crop Productivity in Developing Countries AgEcon
Evenson, Robert E..
Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling “disadvantaged” production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific “trait” improvements. But these GM products can be installed on Green...

Perceived Risk is Important for Consumers’ Acceptance of Genetically Modified Foods, but Trust in Industry not Really: A Means-End Analysis of German Consumers AgEcon
Boecker, Andreas.
Applies the means-end approach to investigate how German consumers’ relate GM food attributes to values via perceived consequences in their purchase decisions. Analyses in particular the importance of risk-related dimensions and issues of (dis)trust for different levels of purchase intentions. Identifies two segments: rejecters (n=24) and accepters (n=36). Finds considerable similarities in means-end chains between segments, in particular that risk plays a much bigger role than trust for purchase intentions. Furthermore, for both segments the link between trust and risk is found to be weak which implies to reconsider results from previous empirical studies pointing out the strong interaction of trust and perceived risk.

SHOULD THE UNITED STATES REGULATE MANDATORY LABELING FOR GENETICALLY MODIFIED FOODS? AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
Public debate continues over whether the United States should regulate genetically modified (GM) foods by imposing a mandatory labeling policy. This paper develops a model that shows that a voluntary GM-labeling policy results in higher welfare than a regulated mandatory GM-labeling policy, if consumers can accurately read the signals in each market. We then develop an experiment that shows consumers behave as if they can accurately identify signals for GM foods. Our model and results support the perspective that the United States has been prudent in fending off calls for regulations demanding a mandatory GM-labeling policy.

Some Problems in Estimating Willingness to Pay with Contingent Valuation Surveys: Case for Consumer Acceptance of Genetically Modified Food AgEcon
Chern, Wen S.; Kaneko, Naoya.
This paper reports results from a U.S. national telephone survey on genetically modified foods. The objectives of this paper are to determine the effect of "indifference" response on the estimate of willingness to pay and to test the assumption of common marginal utility of income among respondents.

The Case For and Against Import Embargoes on Products of Biotechnology AgEcon
Gaisford, James D.; Chui-Ha, Carol Lau.
This article examines alternative trade policy responses available to an importing country with concerns over innovations in biotechnology. Regardless of the policy response, the importing country may be worse off after a new genetically modified food (GMF) is introduced. While an import embargo may be preferable to allowing free access to unlabelled GMF imports, permitting labelled imports is typically superior to an embargo. Thus, import embargoes on products of biotechnology should not be generally allowed. The paper provides surprising support for the existing WTO provisions on Technical Barriers to Trade, but suggests significant potential problems with the recently negotiated Biosafety Protocol.

THE ROLE OF SOCIOECONOMIC FACTORS AND LIFESTYLE VARIABLES IN ATTITUDE AND THE DEMAND FOR GENETICALLY MODIFIED FOODS AgEcon
Heiman, Amir; Just, David R.; Zilberman, David.
Consumer resistance is a key barrier to the diffusion of genetically modified foods (GMFs). Several studies have shown that consumers in general have a negative attitude toward GMFs. Through analysis of a survey conducted in Israel, we find consumer attitudes toward GMFs to be context specific, differing based on the available alternatives. Consumers responded positively to genetically modified meats when given the alternative choice of meats produced with hormones or dyes. We also address the importance of gender, education, and being religious on the consumer's attitude toward GMFs. Both education and being religious have significant effects on attitude, while gender does not.

Trust in Authorities Monitoring the Distribution of Genetically Modified Foods: Dimensionality, Measurement Issues, and Determinants AgEcon
Bocker, Andreas; Nocella, Giuseppe.
Based on a combined internet and mail survey in Germany the independence of indicators of trust in public authorities from indicators of attitudes toward genetically modified food is tested. Despite evidence of a link between trust indicators on the one hand and evaluation of benefits and perceived likelihoods of risks, correlation with other factors is found to be moderate on average. But the trust indicators exhibit only a moderate relation with the respondents' preference for either sole public control or a cooperation of public and private bodies in the monitoring of GM food distribution. Instead, age and location in either the New or the Old Lander are found to be significantly related with such preferences.

U.S. Consumers' Willingness to Pay for Food Labeled 'Genetically Modified' AgEcon
Onyango, Benjamin M.; Nayga, Rodolfo M., Jr.; Govindasamy, Ramu.
This study analyzes U.S. consumers' choice of cornflakes under five different labeling statements. Using a nationwide survey and choice modeling framework, results indicate that consumers value labeling statements differently, depending on the information contained on the label. The random parameter logit model results indicated that, compared to cornflakes that have no label information, cornflakes labeled "contains no genetically modified corn" have a value of 10 percent more, the label "USDA approved genetically modified corn" has a value of 5 percent more, and the label "corn genetically modified to reduce pesticide residues in your food" has a value of 5 percent more. The results also suggest that consumers negatively valued the label "contains...
