New Developments in Agricultural Policy Modelling and Consequences for Managing the Policy Analysis Systems AgEcon
Van Huylenbroeck, Guido; Lauwers, Ludwig H.; Fernagut, Bruno.
Last decade, the importance of multifunctionality and environmental issues in agricultural policies has been growing. This shift in scope of agricultural policy instruments implies an adjustment of the conventional ex-ante policy analysis systems. New requirements on input and output parameters will be needed. The objective of this paper is to show how the input/output management can be improved. Focus is on how the information management by the system can enhance the policy analysis and decision making and facilitate information flow and social support from the stakeholder debate.

Multi-input Multi-output Farm-level Cost Function: A Comparison of Least Squares and Entropy Estimators AgEcon
Polome, Philippe; Fernagut, Bruno; Harmignie, Olivier; Frahan, Bruno Henry de.
We introduce a modification of the quadratic-Leontieff multi-output cost function that is particularly suitable for the data of the Farm Accountancy Data Network. We present least squares and entropy estimates of that function and compare their results for a sample of crop farms. Our results are encouraging for the use of entropy estimators in cases in which farms are not assumed to share the same technology. Our approach can be seen as an extension of the Positive Mathematical Programming approach (Howitt, 1995). The extension consists in an explicit specification of inputs in the cost function and in the possibility of modeling several farms simultaneously.

Effects of a flat rate introduction: shifts in farm activity and impact on farmers' income AgEcon
Marchand, Fleur L.; Buysse, Jeroen; Campens, V.; Claeys, Dakerlia; Fernagut, Bruno; Lauwers, Ludwig H.; Van der Straeten, Bart; Van Huylenbroeck, Guido.
Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land) compared to the current historical system (payments based on individual historic entitlements). Impact on production and income of arable, dairy and cattle farms of two different flat rate scenario's, is assessed with a farm-based sector model for Flanders. The model maximizes income at farm level, calibrated to observed farming behavior in 2001-2003. Farm data can be selected by farm type, size and region, simulations could be run for specific sub sectors, size...
