Consumers' Food Choices with Voluntary Access to Genetic Modification Information

"The effects on product choices of voluntarily accessed information are examined in the context of an experimental survey relating to genetically modified food. The data and analysis in this study avoid the assumption that information made available or given to consumers is equivalent to information processed by consumers. Instead we focus on information access behavior. Three different approaches to model this behavior are applied in a Bayesian estimation framework, including conditional logit (CL) models based on the full sample, ex post analysis of individual parameters from mixed logit models, and CL models within the different information scenarios. All three approaches give consistent results. However, the assumption of voluntary information access generates different results than assuming that all information is processed. The results of the analysis show that different types of information do have impacts on consumers' product choices. The nature of these effects appears to be influenced by voluntary access to information." Copyright 2006 Canadian Agricultural Economics Society.
