Résumé
The objectives of this paper are therefore twofold: (i) to provide insights into the way farmers perceive agri-environmental schemes. (ii) to design a methodology in order to measure the relative preference of farmers for three types of agri-environmental payments rules: payments based on compliance costs; payments based on environmental contributions; and payments based on needs for income support. This question echoes the debate on equity and justice principles which often defines three rules for a fair allocation: the accountability principle, the efficiency principle, and the needs principle (Konow, 2001). We design a choice experiment in which farmers can choose between different payment rules. A preliminary survey conducted in Lozere (France) allows us to analyse with a binomial logit model how these preferences are structured.
