 +      <P>CAPRI is a partial equilibrium model for the agricultural sector developed for policy impact assessment
 +
 +      of the Common Agricultural Policy and trade policies from global to regional scale with a focus on the EU.

 +
 +          to directly implement most policy measures with highly differentiated
 +
 +          set of activities. Allocation based on profit maximising behaviour calibrated
 +
 +          to exogeneous elasticities (animals) and estimated multi-product cost
 +
 +          functions (annual crops); provision of nutrient balances and gas emissions with global warming
 +
 +          potential based on production system. Template approach with structurally identical models
 +
 +          which differ in parametrization. Cover completely EU agriculture (280 regional models or 1.900 farm type models) <A HREF='https://www.capri-model.org/dokuwiki/doku.php?id=capri:concept:supply'> read more ..</A></P></LI>
