Goal: To set the optimum price for a new product Discrete choice models • Assumptions • Participants must be knowledgeable • The decision rule is “buy-not buy” • Select a subject pool (sample of existing clients) • Divided them into groups (3, 5, etc.) of at least 100 • Interview them (on-line survey)
GMO Wheat • GMO wheat (like GMO soy) has a gene inserted that increases resistance to a common general herbicide (24-D) aka glyphosate or “Round-up” • The advantage is that the farmer can apply 24-D to the field, even with the crops growing, to kill all weeds, but leave the crop standing. • The lowers costs and also allows the farmer to reduce the use of herbicides (since one does not need to tailor herbicides to the type of weed.
Survey Process • Famers answer a range of questions about herbicide use and understanding of GMO products (Most have a good understanding) • These initial questions serve to orient the farmer to the topic. • Then each group is asked a question… • Would you buy Odyssey seed if it were $15 per acre (group 1); $20 per acre (group2)….
Assuming that farmers will not change their planting (not the case!), we can calculate the total revenue for each price
