A Meta-Analysis of Genetically Modified Food Valuation Studies AgEcon
Lusk, Jayson L.; Jamal, Mustafa; Kurlander, Lauren; Roucan, Maud; Taulman, Lesley.
A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. To examine this body of work, a meta-analysis was conducted of 25 studies that, in aggregate, report 57 valuations for GM food. Findings indicate as much as 89% of the variation in existing value estimates for genetically modified food can be explained by an econometric model that controls for (a) the characteristics of the sample of consumers studied, (b) the method for eliciting consumers' valuation, and (c) characteristics of the food being valued. Each of these factors has a statistically significant effect on estimated premiums for non-GM food. Results of...

An analysis of trade related international regulations of genetically modified food and their effects on developing countries AgEcon
Gruere, Guillaume P..
This paper reviews current trade-related regulations of genetically modified (GM) food and discusses their effects on developing countries. There is a large heterogeneity in current import approval and marketing policies of GM food worldwide. At the international level, the harmonization efforts are led by the Codex Alimentarius Commission, the Cartagena Protocol on Biosafety and the World Trade Organization. While internationally harmonized guidelines for safety approval have been finalized, we show that there is no clear consensus on labeling regulations for GM food, and there is an increasing risk of conflicts among international agreements. We analyze the GM food regulations of two large rich importers, Japan and the European Union (EU) and discuss...

Consumer Attitudes towards Genetically Modified Foods in Emerging Markets: The Impact of Labeling in Taiwan AgEcon
Ganiere, Pierre; Chern, Wen S.; Hahn, David E.; Chiang, Fu-Sung.
In 2001, Taiwan enacted a law for genetically modified food (GM foods) labeling. Beginning January 1st 2003, food containing more than 5% of GM ingredients must be labeled. Taiwan imports most of its soybeans from the United States. In order to assess the effects of the new policy, a telephone survey was conducted in 2002. A total of 257 interviews were completed. A typology of consumers' attitudes towards GM foods is constructed from the use of a multiple correspondence analysis and a classification method. Four profiles are identified: proponents, 52%, moderate opponents, 32.5%, extreme opponents, 12.5%, and those with no opinion, 5.5%.

Consumers' Preferences for GM Food and Voluntary Information Acquisition: A Simultaneous Choice Analysis AgEcon
Veeman, Michele M.; Hu, Wuyang; Adamowicz, Wiktor L..
Previous research studies directed at the influence of information on consumers' preferences and choices of food in the context of genetically modified (GM) food assume that information is exogenous, in that this is provided to consumers from external sources. Information made available to consumers is also typically treated as being received and processed. Other literature and observation suggests that these two features tend not to apply in practice. Using data from a choice experiment on consumers' choices for genetically modified food in which respondents were able to voluntarily access information, this study allows information to be endogenous; consumers' product choices and information access decisions are examined within a simultaneous choice...

Consumers' Trust in Government and Their Attitudes Towards Genetically Modified Food: Empirical Evidence from China AgEcon
Qiu, Huanguang; Huang, Jikun.
Understanding the determinants of consumer's acceptance towards genetically modified food (GMF) is critical important for future biotechnology development. Among many factors, consumers' trust in government has increasingly received great attentions in the literature. However, accurately quantifying impact of consumers' trust in government on their GMF attitudes is difficult because researchers often encounter many difficulties in empirical estimation. Overall goal of this study is to empirically quantify the impact of consumers' trust in government on their attitudes towards GMF in China. An econometric model on consumer's trust in government and their attitude towards GMF is developed and estimated based on a unique data set collected by the authors in...

Do defaults matter? Willingness to pay to avoid GM food vis-à-vis organic and conventional food in Denmark, Great Britain and Spain AgEcon
Costa-Font, Montserrat; Tranter, Richard B.; Gil, Jose Maria; Jones, Philip J.; Gylling, Morten.
The introduction and communication of new technologies in the food industries has given rise in the past to some scientific uncertainty that hampers informed choice. Here we draw upon the case of Genetically Modified (GM) technology and, in particular, on different types of GM food, to investigate consumers’ behavioural reactions to GM food as well as their willingness to pay for avoiding GM food in three EU countries, Denmark, GB and Spain in 2007. Our unique contribution lies in that our empirical analysis concerns two food products containing different characteristics. In particular, we compare consumers’ reactions to cornflakes (to represent a processed food) and tomatoes (to represent a 'fresh' food) juxtaposed with GM and conventionally produced...

Does Price Signal Quality? Strategic Implications of Price as a Signal of Quality for the Case of Genetically Modified Food AgEcon
Hwang, Yun Jae; Roe, Brian E.; Teisl, Mario F..
We add to the limited empirical literature on consumers' use of price as a quality signal by testing if the traditional downward-sloping consumption-price relationship fails to hold for GM products using data collected from a nationally representative mail survey featuring several hypothetical product choice scenarios. Statistical evidence is mixed across the three products investigated but suggests that survey respondents use price as a signal of the quality of GM products. Implications for firm strategy are discussed.

Genetically Modified Food and International Trade: The Case of India, Bangladesh, Indonesia, and the Philippines AgEcon
Gruere, Guillaume P.; Bouet, Antoine; Mevel, Simon.
Genetically modified (GM) food crops have the potential to raise agricultural productivity in Asian countries, but they are also associated with the risk of market access losses in sensitive importing countries. We study the potential effects of introducing GM food crops in Bangladesh, India, Indonesia, and the Philippines in the presence of trade-related regulations of GM food in major importers. We focus on GM field crops (rice, wheat, maize, soybeans, and cotton) resistant to biotic and abiotic stresses, such as drought-resistant rice, and use a multi-country, multi-sector computable general equilibrium model. We build on previous international simulation models by improving the representation of the productivity shocks associated with GM crops, and by...

GENETICALLY MODIFIED FOOD CROPS AND PUBLIC HEALTH Acta biol.Colomb.
ACOSTA,ORLANDO; CHAPARRO,ALEJANDRO.
The progress made in plant biotechnology has provided an opportunity to new food crops being developed having desirable traits for improving crop yield, reducing the use of agrochemicals and adding nutritional properties to staple crops. However, genetically modified (GM) crops have become a subject of intense debate in which opponents argue that GM crops represent a threat to individual freedom, the environment, public health and traditional economies. Despite the advances in food crop agriculture, the current world situation is still characterised by massive hunger and chronic malnutrition, representing a major public health problem. Biofortified GM crops have been considered an important and complementary strategy for delivering naturally-fortified...

Neoclassical consumer theory and genetically modified food AgEcon
Kaye-Blake, William.
Three axioms underpin consumer choice in neoclassical theory: weak order, independence, and continuity. Two of these axioms may not hold, however, for consumers’ choices regarding genetically modified (GM) food. Consumers may evaluate product attributes differently depending on whether the food is GM or not, violating attribute independence. Some consumers may not want GM food at all, violating continuity. The axioms were empirically investigated with a choice experiment survey. The paper discusses evidence of violations of both independence and continuity, as well as a non-neoclassical approach to modelling consumer choice.

Public Policy and Endogenous Beliefs: The Case of Genetically Modified Food AgEcon
Lusk, Jayson L.; Rozan, Anne.
When individuals have limited information and are uncertain about the quality of a good, government policy, or the lack thereof, can serve as a signal to consumers about the likelihood of realizing alternatives states of nature. In this paper, we focus on a controversial beliefs about government intervention: the market for genetically modified food. Data from a mail survey were used to estimate an econometric model where beliefs about labeling policy, beliefs about the safety of genetically modified food, and willingness to consume genetically modified food are endogenously determined. Results indicate that consumers who believe the government has a mandatory labeling policy for genetically modified food are more likely to believe genetically modified...

Seeking a Common Path: Structuring Multistakeholder Dialogue on Agricultural Biotechnology in Africa AgEcon
von Grebmer, Klaus; Omamo, Steven Were.
This paper analyzes an ongoing effort by national, regional, and international partners to raise awareness, promote dialogue, and catalyze consensus-building mechanisms among stakeholder groups on the role of biotechnology in agricultural development and food security in southern Africa. Stakeholders include public bodies, the private sector, and civil society. The paper argues that while responsible adoption of agricultural biotechnology promises significant gains to the countries of southern Africa, governments must clarify its specific role, improve policies for its application, and assess the place of biotechnology in broader development strategies. The issues that surround the introduction, creation, and application of agricultural biotechnology in...

Structural Equation Modelling of Consumer Acceptance of Genetically Modified Food (GM) in the Mediterranean Europe: Spain, Greece and Italy. AgEcon
Costa-Font, Montserrat; Gil, Jose Maria.
The inception of genetic modification (GM) techniques in food production conveys both opportunities - improve food production technologies and/or product differentiation - and risks - dread of a change of the technological status quo, ambiguity in the food properties..…. Hence, some research has been devoted a careful understanding of consumer's reactions towards to GM food. However, unavoidably individual's perceptions involve taking into account several factors at a time that cannot be taken as given or exogenous such as traditional food values and trust in information sources primarily. This paper contributes to the literature by examining the behavioural process that drives individual's perceptions to GM food using a methodology that allows accounting...

The Impact Of Socio-Demographic Factors And Political Perceptions On Consumer Attitudes Towards Genetically Modified Foods: An Econometric Investigation AgEcon
Antonopoulou, Lina; Papadas, Christos T.; Targoutzidis, Antonis.
This survey-based paper investigates the impact of socio-demographic factors, along with political perceptions, as expressed by attitudes towards globalization, on consumer attitudes towards GM foods, in Greece. Different aspects of consumer attitudes regarding GM foods are examined, such as general preference, banning, labeling, intention to purchase them at a sufficiently low price, the nutritional category of food product and the proximity of the genetic modification to the final product. Econometric analysis using Logit and Probit models was conducted. Estimates clearly show that in general, attitudes towards GM foods are not affected by socio-demographic characteristics. However, political perceptions are a significant influential factor.

UK Consumers' Willingness-to-Accept (WTA) GM Food AgEcon
Moon, Wanki; Rimal, Arbindra; Balasubramanian, Siva K..
Our study uses contingent valuation survey data (WTA and WTP) collected in the UK to examine consumers' behavioral intention with regard to GM food. In particular, we characterize respondents who selected "Don't Know" and "Protest" options in WTP questions in terms of what they would do when offered discount for GM food.

Who Should Certify the Safety of Genetically Modified Foods? AgEcon
Baker, Gregory A.; Mazzocco, Michael A..
Two methods of addressing consumer concerns regarding the use of genetically modified foods are evaluated using conjoint analysis – the use of a familiar brand and government certification. In one survey, consumers were asked to rate hypothetical products based on brand, price, and production technology attributes. In a second survey, consumers rated hypothetical products that included government certification, price, and production technology attributes. Both the individual and aggregate results indicate that government certification would be more effective at assuaging consumers concerns than would the use of a familiar brand, although a familiar brand was sufficient to address consumer concerns for a significant number of respondents. The analysis also...

Willingness to Pay (WTP) a Premium for Non-GM Foods versus Willingness to Accept (WTA) a Discount for GM Foods AgEcon
Moon, Wanki; Balasubramanian, Siva K.; Rimal, Arbindra.
In a survey of UK consumers, we elicited their willingness to accept (WTA) a discount for GM foods and willingness to pay (WTP) a premium for non-GM foods in order to assess their valuation on the non-GM characteristic in food products. Mean WTA is found to exceed mean WTP, suggesting the valuation of the non-GM characteristic reflects an endowment effect, imperfect substitutability between GM and non-GM foods, or both. Regression results show that perceived risks (benefits) associated with GM foods significantly increase (decrease) WTA and WTP estimates. Additional regression models using the difference between WTA and WTP as the dependent variable indicate that risk (benefit) perceptions increased (decreased) the discrepancy between WTA and WTP...

Would Consumers Value New Functional Properties of GM Food? A Choice-Modeling Approach for Rapeseed Oil AgEcon
Hartl, Jochen; Herrmann, Roland.
European consumers and, in particular, German consumers are known to be very critical towards the introduction of genetically modified (GM) foods. It is analyzed here whether German consumers do reject second-generation GMO foods, too. Whereas first-generation GM crops induced producer-related benefits, second-generation GM crops are associated with consumer-oriented benefits like an improvement of nutritional quality. The determinants of demand for second-generation GM rapeseed oil are investigated within an online survey of 1556 German consumers. It is elaborated how two functional properties of that product matter; i.e. long-chain omega 3 fatty acids and the cholesterol-lowering effect of phytosterols. It turns out that GMO rapeseed oil is neglected by...
