The FCP-group is itself a CET aggregate of Cattle and Raw Milk (both Pasture), ‘Sugarcane and Beet’ (SUG), and the group of ‘Cereal, Oilseed and Protein crops’ (COP). Here, the elasticity of transformation is o2. Finally, the transformation of land within the upper nest, the COP-group, is modeled with an elasticity o3. In this way the degree of substitutability of types of land can be varied between the nests.
