Progres techniques et productivite totale des facteurs : analyse theorique et application a l'agriculture francaise

Abstract

Typically measures of total factor productivity growth have been based on a non parametric framework : this residual approach is based on divisia indexes of inputs and outputs and likens technical change to the percentage growth in total factor productivity. Unfortunately, this simple equivalence is true only if several assumptions are satisfied : Hicks neutral technical change, constant returns to scale, separability between inputs and outputs, perfectly variable inputs and outputs and competitive markets for all commodities. When one of these assumptions is not satisfied, the parametric or economic approach is a convenient alternative even if the representation of technical change in the production function or in its dual (profit, cost or revenue functions) is, with no doubt, too restrictive. As a final objective both approaches are applied to French Agriculture (1960-1984).
