This study proposes an econometric analysis of household fuelwood demand in France. The choice concerning the energy used for heating is modeled, stressing the combination between one type of energy used as a main source and another one used as a back-up. This endogenous decision has an impact...

[fre] Les problèmes d'intrusion d'eau salée dans les aquiferes côtiers constituent aujourd'hui l'une des principales causes de détérioration de la qualité de leurs eaux. L'eau de mer, plus dense que l'eau douce, envahit ces aquiferes dès que les prélèvements sont suffisamment intenses...

Domestic and foreign forest products consumptions are considered imperfectly substitutable in the French Forest Sector Model (FFSM). This assumption is justified by product heterogeneities that depend on production places, by the consumers habits or by the market structure. It leads us to...

This paper studies the optimal growth when research and development are explicitly distinguished. To this end, we perform the quantitative welfare analysis of an original model based on (i) a matching process between research and development and (ii) a competitive search process that determines...

Network losses and returns are importantissues for water resource management, that are addressed in thispaper by modeling the structure of production for municipal waterutilities with two outputs: water sold to final customers andwater network losses. We propose a measure of economies of scopeto...

[eng] Performance and efficiency in the utilities : The case of delegated water utilities. . In this paper we offer an empirical analysis of the operating costs of drinking-water supply delegated to private companies in France. An important factor in our modelling is the allowance for water...
