  3. PMP

  4. SEPALE: main characteristics • Belgian FADN data • Simultaneous optimisation of farm level profit functions • Simulation results can be aggregated according to the farm's localisation, type and size • Exchange between farms of land and quota • Constraints: • Land at regional level • Quota at farm and regional level • Animal feed through CES function • Solved with GAMS

  5. SEPALE: calibration of profit function P X + subsidies – Q/2 X² - H X Q and H are cost function parameters P: price X: production • 1st derivative to X is zero: MC = MR P = Q X + H • Total costs observed includingseeds, fertilizers, pesticides, contract work and land = Q/2 X² - H X • Two equations and two unknown parameters  parameters can be directly calculated • Constraint to prevent that total land use of the sample does not change

  6. MTR • single farm payment replaces the direct payments to activities • direct aid is linked to compliance with rules, called cross-compliance • Modulation: system of progressive reduction of direct payments: 5% in 2007 beyond 5000 euro per farm

  7. MTR in SEPALE: decoupling • The reference amount is divided over the reference area to assign the payment entitlement per ha for each farm • Area with eligible crops, all crops except potatoes and vegetables in open air, can activate the subsidy entitlements

  8. MTR in SEPALE: decoupling • Three situations could occur: 1. The same area of eligible crops as during the reference period: same direct payments 2. Increasing eligible area does not increase the amount of direct payments. 3. The amount of direct payments decline by a reduction of the eligible land

  9. MTR in SEPALE: decoupling • two farm level constraints should be added: Activated area ≤ Reference area Activated area ≤ Eligible area • The direct payments extend the profit function, as follows: Profit + activated area * reference amount

  10. MTR in SEPALE: modulation • Should be added during optimisation because farms can avoid reductions by transfers of direct payment entitlements • Two parameters controlled by policy: • Modulation threshold: amount free from reductions • Modulation percentage: percentage reduction

  11. MTR in SEPALE: transfers of entitlements • Can occur both with as without transfer of land. • Each member state can confiscate a certain percentage of the transferred entitlements. • Transfers with land: 10% of the entitlement can revert to the national reserve • Transfers without land: up to 30% can revert to the national reserve.

  12. MTR in SEPALE: transfers of entitlements • 7 constraints and 7 extra variables • Calculation of the amount of not activated entitlements • Calculation of the average value of not activated entitlements • Calculation of free eligible land per farm • Calculation of acquired land • Constraint to prevent transfers beyond the free eligible land • There should be more not activated entitlements than transferred entitlements • Complementary slackness constraint to prevent farms from being buyer and seller at the same time

  13. Impact analysis • 159 arable and cattle farms for which data were available for the year 2002 • Impact on supply and gross margin of: • Decoupling ratio • Modulation percentage • Modulation threshold • Transfers of direct payments?

  14. Decoupling – land use

  15. Decoupling – gross margin

  16. Modulation percentage – gross margin

  17. Modulation threshold – gross margin

  18. no progress at all in the solution process. the optimality criteria have not been satisfied ABS function Discontinuities Complementary slackness constraint multi-extremal decision models can be very difficult to solve, standard optimization strategies are not always sufficient Problem: numerical optimisation

  19. Conclusion + discussion SEPALE: individual farm-based sector model • Advantages: • to account for the individual farm structure • to simulate impact according to farm characteristics • to simulate transfers between farms • Disadvantages: • Limited data for calibration at farm level • More complex model structure

  20. Further research • Functional form • Environmental indicators • Demand side – link with other EU member states • Transaction costs • Risk
