Les producteurs de viande bovine des Pays de la Loire face à la réforme de la PAC

CAP reforms will have important consequences on income. By help of supply models which take into account the major policy tools, a prospective approach allows us to estimate impacts of various scenarii on agricultural incomes. The studied reform is focused on price - income decoupling. It is viewed according to criteria of equity and efficiency from the economic theory. The "new CAP" seems not to be suitable. Only the increasing transparency of transfers could be a good mean to measure the social cost of agricultural substainability. Presented results allow us to focus on agricultural gross margins and public budget expenditure (except refunds to exports). Important differences appear between crop farmers and breeders. These differences have to be seen from a regional point of view. It could lead to regional agricultural policies as the counterpart of various social preferences to the agricultural sector.
