3,972 rated or chosen profiles from 331 respondents, in up to 6 tasks of 2 profiles varying on 5 attributes.
One of 6 tables from the same source; this one is the legume_farmers_it table. The others are listed under Related tables.
| Description | Discrete choice experiment: Italian farmers (Qualtrics via IPSOS Europe, Nov 2024; n = 331, of whom 222 flagged high-quality by the authors) chose among two plans and a 'Neither' alternative on 6 cards; profiles describe legume rotation plans varying the legume (green pea / yellow pea / chickpea / soybean), share of cereal land rotated, sales agreement, conservation agriculture with or without free technical assistance and return per hectare. Outcome is the chosen option (opt-out allowed); a follow-up forced choice after 'Neither' is choice_forced. |
