摘要：A revealed preference auction experiment is used to elicit values for two attributes, one relating to genetic modification and the other to country of origin of the food product, canola oil. A premium for a non-GM canola oil is found to approximate CA$0.4 to $0.6 per litre. Auction format effects are found and hypotheses as to why these may occur are suggested.
