La demande d'énergie des industries laitières : une analyse microéconomique

[eng] The energy demands in dairy industries : a micro-economic analysis, by Alain Bousquet, Marc Ivaldi, Norbert Ladoux. An empirical analysis examines substitution opportunities for various forms of energy in the dairy industry. First, we estimate a demand function system for energy factors in order to grasp their substituability. It is then possible to understand the trends in the structure of the energy consumption. Zero expenditures in the sample require a special treatment when the model is specified. And this is true for two different stages : the theoretical one as well as the econometric one. The model is similar to qualitative variable models such as the general Tobit model. [fre] La demande d'énergie des industries laitières : une analyse microéconomique, par Alain Bousquet, Marc Ivaldi, Norbert Ladoux. Cet article s'intéresse à l'analyse empirique des possibilités de substitutions entre formes d'énergie, pour les entreprises du secteur des industries laitières. L'objectif est d'estimer un système de fonction de demande de facteurs énergétiques et d'appréhender le degré de substituabilité entre chacune de ces formes, et, ainsi, de mieux comprendre l'évolution de la structure de la consommation totale d'énergie. La présence de dépenses nulles dans l'échantillon requiert une attention particulière lors de la spécification du modèle, au point de vue théorique tout d'abord et économétrique ensuite. Le modèle proposé s'apparente aux modèles à variables qualitatives du type Tobit généralisé. [ger] Der Energiebedarf der Milchwirtschaftsbetriebe : eine mikroökonomische Analyse, von Alain Bousquet, Marc Ivaldi, Norbert Ladoux. Dieser Artikel befasst sich mit der empirischen Analyse der Substituierbarkeit von Energieformen in Milchwirtschaftsbetrieben. Er zielt darauf ab, ein Funktionssystem hinsichtlich der Nachfrage nach Energiefaktoren zu schätzen und den Substituierbarkeitsgrad zwischen jeder dieser Formen zu erfassen, um die Entwicklung der Struktur des gesamten Energieverbrauchs besser zu verstehen. Die in der Stichprobe beobachtete Nullausgabensituation erfordert bei der Spezifikation des Modeils zuallererst unter theoretischem sodann unter ökonometrischem Gesichtspunkt besondere Aufmerksamkeit. Das vorgeschlagene Modell weist ähnliche Merkmale auf wie die Modelle mit qualitativen Variablen vom verallgemeinerten Tobit-Typ. [spa] La demanda de energia de las industrias lecheras : un análisis microeconómico, por Alain Bousquet, Marc Ivaldi, Norbert Ladoux. En este artículo se procede a un análisis empírico de las posibilidades de substitución entre formas de energía para las empresas del sector de las industrias lecheras. Tiene por objetivo estimar un sistema de función de demanda de factures energéticos y aprehender el grado de substituibilidad entre cada una de estas formas y, de este modo, entender mejor la evolución de la estructura del consumo total de energía. La existencia de gastos nulos en la muestra requière una atenciôn particular cuando se especifica el modelo, ya sea teóricamente o econométricamente. El modelo propuesto se parece a los modelos de variables cualitativas del tipo Tobit generalizado.
