CAPRI model

The CAPRI (Common Agricultural Policy Regionalised Impact) model is a tool for ex-ante impact assessment of agricultural and international trade policies with a focus on the European Union. As an economic partial comparative static equilibrium model for agriculture, its core consists of two interlinked modules: the supply module, covering about 280 regional aggregate programming models covering the EU27, Norway and Western Balkans at the NUTS 2 level and the market module, a global spatial multi-commodity model for about 50 agricultural commodities, which together allow calculation of a wide range of economic and environmental indicators.Henrichsmeyer, W., Britz, W., Heckelei, T., Meudt, M., Sander, R.:

A spatial downscaling component allows impact assessment at the 1x1 km grid level for EU27.Leip, A., Marchi, G., Koeble, R., Kempen, Britz W. and Li, C.:

CAPRI was developed and improved in a suite of EU funded research projects ([https://web.archive.org/web/20080614000943/http://www.ilr1.uni-bonn.de/agpo/rsrch/capri/caprifp4_e.htm CAPRI], [https://web.archive.org/web/20080613225944/http://www.ilr1.uni-bonn.de/agpo/rsrch/capstr/capstr_e.htm CAP-STRAT], [https://web.archive.org/web/20090214040737/http://www.ilr1.uni-bonn.de/agpo/rsrch/dynaspat/dynaspat_e.htm CAPRI-Dynaspat]). Past applications include analysis of different reform steps of the Common Agricultural Policy such as Agenda 2000,Britz W. and Heckelei T.:
