+ | Disaggregation by farm type mainly aims to capture heterogeneity in farming practises and farms within a region, in order to reduce aggregation bias in response to policy and market signals, with a focus on farm management, farm income and environmental impact. The argument is especially striking when policy instruments are either targeting specific farm types or are modulated depending on farm characteristics. | ||

+ | ==== Characteristics of the farm types in CAPRI ==== | ||
+ | |||
+ | * Unordered List ItemFull integration in the CAPRI modelling chain | ||
+ | |||
+ | * This which ensures price feedback based on sequential calibration with the global, large-scale market model. Linking these other farm models to existing market models is far from easy due to differences in product definitions, | ||
+ | |||
+ | * The strict and consistent top-down disaggregation | ||
+ | |||
+ | * This ensures a harmonized data set across regional scales and farm types. | ||
+ | |||
+ | * A farm type is a supply module | ||
+ | |||
+ | |||
+ | The supply model for each farm type and each region consists of independent aggregate non linear programming models, representing as an aggregate all activities of all farms falling into that type and a specific administrative regional unit at Nomenclature of Territorial Units for Statistics level II (NUTS2). | ||
+ | |||
+ | ==== Features of the supply model ==== | ||
+ | |||
+ | |||
+ | Farm supply models, similar to the regional ones, capture the premiums paid under the CAP, NPK balances and a module with feeding activities covering nutrient requirements of animals. Constraints, | ||
+ | |||
+ | ==== Prices ==== | ||
+ | |||
+ | |||
+ | Prices are exogenous in the supply module and provided by the market module, with which they are solved sequentially until convergence. Grass, silage and manure are assumed to be non-tradable and receive internal prices based on their substitution value and opportunity costs. | ||
+ | |||
+ | ==== Coverage ==== | ||
+ | |||
+ | A maximum of nine of the most important farm types per region, plus they always include a residual farm type to exhaust regional production as well as input and primary factor use defined by a selction routine developed in close cooperation with IPTS-SUSTAG | ||

+ | The up to nine farm groups are characterized by “type of farming,” see Table 1, defined by the relative contribution of different production branches to the gross margin of the farm (European Commission, CD 85/377/EEC, Article 6), and the “economic size class” based on “European size units” (ESU), a concept defined in Chapter IV Article 8 in CD 85/377/EEC and Annex III. | ||
