Dynamique de la concurrence dans l'industrie avicole française

The level of technology employed by an individual farmer depends on his climatic, edaphic, genetic, human and economic resources. A synthetic way of describing the diversity of technological models used in the different regions is to represent technology by means of « engineering production functions ». The difficulty for the construction of those functions is to depend upon a scarce number of observations which do not represent the whole set of feasible choices. An interesting alternative is to use agricultural simulation models, which represent a technical production function in its original sense, with the purpose of establishing the input-output coefficients for the different combinations of production factors.
