Dairy production in the French western regions and the CAP health check: a bio-economic model to discuss farmer’s behavior

Abstract : This paper analyzes the productive and economic implications for dairy farms in the west of France (four types), of the abolition of milk quotas. A model based on the linear programming method is developed by integrating a set of constraints (zootechnical, agronomical, environmental, structural and regulatory) to represent, as closely as possible, the operation of a dairy farm. This model, which assumes that each agent seeks to maximize its income, incorporates the concept of risk aversion to price volatility (with the Utility efficient programming method). The results of these simulations show that French farmers have a strong potential for milk production even with the same farm structure (without acquisition of land or without additional investment in buildings). The volume of milk production per farm is little influenced by the price ratios between milk and cereals. However, these have an impact on the rotation structure. The main interest of this work is to identify and prioritize the major factors which, with the removal of milk quotas, would have an impact on the ability of farms to expand their production or not.
