Abstract: This study assesses consumers' willingness to purchase genetically modified (GM) food products with two different types of benefits: an input (i.e., reduced pesticides) and an output trait benefit (i.e., nutritionally enhanced). Data were collected using a telephone survey of an Italian households sample. Discrete choice approach is used to elicit the purchase intentions of the respondents. Four separate probit models are estimated to examine the effect of various factors on choices. Results suggest that majority of Italians are not willing to buy GM food products even if they are nutritionally enhanced. However, more consumers are willing to buy a nutritionally enhanced plant based GM product than a traditional plant based GM (with input trait benefit). Willingness to buy for a nutritionally enhanced animal based GM product and for a traditional animal based GM product with input trait benefit are similar. Consumers unwilling to buy GM food would not buy it even if it is nutritionally enhanced and has lower price. However, there is a niche of consumers who are willing to buy nutritionally enhanced GM food products even at a premium. Knowledge of science and trust in scientists consistently affect Italian consumers' willingness to buy the GM products.
