The Dispersion and Development of Consumer Preferences for Genetically Modified Food - A Meta-Analysis

This paper presents a meta-analysis of 51 primary studies reporting a total of 114 genetically modified food valuation estimates. Results indicate that elicitation methods and formats used in the primary studies affect valuation estimates much more than do sample characteristics. The analysis of average preferences and dispersion of preferences indicates clear differences between regions. Furthermore, region-specific preferences diverge over time.
