Estimation de la demande domestique d'eau potable en France
[fre] Peu de travaux ont été menés pour connaître la demande en eau potable des ménages en France. Nous proposons d'estimer la fonction de demande domestique en eau potable dans deux départements français qui sont relativement similaires du point de vue des ressources en eau mais qui diffèrent en termes de conditions climatiques et de caractéristiques socio-démographiques. Des variables de type socio-économiques et des données météorologiques ont en conséquence été introduites, outre les chiffres de consommation et de prix de l'eau, dans la fonction de demande. Les méthodes économétriques appliquées sont des méthodes spécifiques de traitement de données de panel, ce qui permet d'éviter tout biais dans l'estimation des coefficients. L'estimation séparée des deux échantillons fait apparaître une élasticité-prix de la demande significative, estimée à -0,08 et -0,22 dans les deux départements. L'élasticité revenu n'est significative que dans un département, où elle est estimée à 0,01. [eng] Estimation of the residential water demand function in France Few works have been done on the estimation of the residential water demand in France. We propose to estimate the residential water demand function in two french departments which are relatively similar in terms of water resources endowments but differ concerning climatic conditions and socio-demographic characteristics. Socio-economic and meteorologic variables have thus been introduced, in addition to water consumption and price of water, in the demand function. Specific econometric panel data methods are employed in order to avoid biased coefficients. The results emphasised a statistically significant price-elasticity in the two departments, estimated at - 0.22 and - 0.08. The income elasticity is significant in one of the two departments, evaluated at 0.01.
