L'objectif de cet article est de presenter quelques reflexions methodologiques relatives a la prevision econometrique des effets de regroupement de bureaux distributeurs dans le secteur postal. Deux concepts de fonction de cout sont utilises dans un but de comparaison: la fontion de cout espere...

Dans cet article nous effectuons une analyse econometrique du secteur d'activite "distribution du courrier" de la Poste. Le but est d'obtenir une information quantitative concernant les characteristiques technologiques de ce secteur. Plus particulierement, nous examinons les elasticites des...

The purpose of this paper is to define the concept of expected minimum cost function and to present the methodology for a non parametric estimation of it. Generally, in cost enonometric analysis, inference is made on the cost function, namely the conditional expectation of cost given some level...

We analyse the model in which the latent durations Ti are i.i.d. generated by a distribution F. The statistician observes Yi= min (ti, Ci) and Ai=1I {Ti <= Ci} where ci is a censoring time. The prior probability on F is a Dirichlet process Di (n0F0).

We propose an operational concept of Constrained Strategic Equilibrium (CSE) applicable to a broad class of empirical game theoreticmodels with incomplete information. By restricting the players' strategic sets, we can compute solutions from a strategic form of analyis based upon auxiliary Monte...

Nous adoptopns dans cet article la notion d'equilibre approximatif obtenu a partir d'une regle intuitive. Cette notion repose sur l'idee qu'a la place des strategies complexes a l'equilibre de Nash, les agents utilisent des regles de decision simples et fondees sur l'intuition et le bon sens....

We consider a kernel based approach to nonlinear canonical correlation analysis and its implementation for time series. We deduce various diagnostics for reversible processes and gaussian processes. The method is first applied to a stimulated series satisfying a diffusion equation allowing us to...
