Etude de l'efficience en économie de la production : de nouvelles mesures de l'efficacité et leurs extensions théorie et applications

Abstract : This thesis aims to present two efficiency measures. First, a log-additive distance function is introduced. It is dual to non-linear pseudo cost, revenue and profit functions. This structure means that the relation between factors and products is not constant. Moreover, exponential Luenberger (Chambers, Färe and Grosskopf (1996)) and Luenberger-Hicks-Moorsteen (Briec and Kerstens (2004)) indicators are proposed. Second, a non-linear distance function is defined. It inherits thestructure of CES (Solow (1956)) and CET (Powell and Gruen (1968))functions. The duality theory allows to present non-linear cost, revenue and profit functions. In this sense, non-linear adjusted price functions are deduced. Non-linear prices occur when the production unit faces internal and/or non-linear tariffs. The alpha-returns to scale model (Boussemart, Briec, Peypoch and Tavéra (2009)) is applied to this new non-linear efficiency measure. Indeed, it is shown that returns-to-scale impact efficiency of production units.
