摘要：This article contributes to the ongoing discussion about the impact of different labeling practices on the quality of genetically modified (GM) food products as perceived by the consumer. Thus far, many studies have adopted a stated preferences approach, finding that consumers have different willingness to pay for GM and non-GM products. This article offers an empirically tractable theoretical model that can be used easily to investigate the impact of GM labeling practices on the perceived quality of GM food products, making use of market data.
