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...

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...

A Calibrate Auction-conjoint Experiment to Elicit Consumer Valuation of Sustainable Farming: Is Agro-systems Preservation Relevant? AgEcon
Avitia, Jessica; Costa-Font, Montserrat; Gil, Jose Maria; Lusk, Jayson L..
This paper analyses the role of agro-systems preservation on making food choices. It employs the “Calibrate Auction-Conjoint Valuation method” (CACM), which relates hypothetical conjoint valuation of product attributes with real market behavior using real economic incentives. The paper also allows comparing the hypothetical and nonhypothetical valuations in order to value the difference between the theoretic and the incentive-compatible WTP for a same respondent and within a single experiment. Thus the paper aims at testing for: 1) the internal consistency on people’s behavior towards sustainable agriculture, and 2) the relevance of the price attribute versus agro-ecosystems preservation for a fresh product. Results suggest that Spanish respondents’...

Risk perceptions, risk attitudes and the formation of consumer acceptance of Genetically Modified (GM) food AgEcon
Costa-Font, Montserrat; Gil, Jose Maria.
The influence of risk perception and risk attitudes in the process of accepting genetically modified (GM) food is often ignored, and particularly whether both constructs (latent variables) have a combined effect in explaining consumer acceptance. Similarly, the inclusion of organic product standards juxtaposed to GM food is unknown. This paper attempts to shed some light on this question by examining the decision making process through the use of structural equation modeling (SEM). We use survey data from Spain and a set of theoretical constructs that allow us to identify independent mechanisms underlying individuals’ risk decision making. Our results suggest that the conceptualized model captures the decision making process, and that both perceptions and...
