Technical change at the farm level or changes ininput prices often entail that the firm's supply functionchanges. These changes can take place in numerous ways. Thispaper presents a methodology that increases the consistency insupply responses across various sets of agricultural productsand farm...

A number of economic models have been applied to analyse theCommon Agricultural Policy. The partial equilibrium models CAPRI,ESIM, AGLINK, AGMEMOD and CAPSIM and the general equilibriummodels GLOBE and GTAP are currently integrated in a modellingplatform for Agro-Economic Policy Analysis in the...

We argue in this paper that available econometric estimates of farmers’ risk aversion do notmeasure true farmers’ preferences towards risky outcomes. Available analyses are mostly ofstatic nature and indeed measure the parameters of the synthetic optimal value function ratherthan the deep...

Increasing demand for policy impact assessment regarding social,economic and environmental aspects asks for combined applicationof different models and tools. The paper discusses concepts andchallenges in linking models, taking CAPRI (Common AgriculturalPolicy Regionalised Impact) model as an...

In the context of a long run agricultural outlook on behalf of the European Environmental Agency a new methodology has been developed to systematically integrate external forecasts into a quite detailed agricultural sector model. External forecasts usually provide estimates for the exogenous...
