La plupart des méthodes utilisées pour prédire la consommation d'eau d'irrigation à l'échelle régionale sont fondées sur des modèles biophysiques et les assolements. Leur objectif est de fournir des estimations précises de la "demande d'eau" qui sont utiles pour la gestion des...

, sometimes referred to as modeling ‘tribes', began to engage in productive dialogue in the mid-1990s (IPCC 2001). From this … methodological conversation have emerged modeling approaches that offer a hybrid of the two perspectives. Yet, while individual … publications over the past decade have described efforts at hybrid modeling, there has not as yet been a systematic assessment of …

Les espèces de grand gibier sont considérées à la fois comme des ressources et des nuisibles : valorisées par les chasseurs et responsables de dommages économiques collectifs. L'article se propose de caractériser l'optimum collectif en mobilisant le cadre de l'économie des ressources...

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic...

A Bayesian model averaging procedure is presented that makes use of a finite mixture of many model structures within the class of vector autoregressive (VAR) processes. It is applied to two empirical issues. First, stability of the Great Ratios in U.S. macro-economic time series is investigated,...
