Funded private pillars are well developed in many countries such as the United States, the United Kingdom, Canada, Switzerland and the Netherlands. In France, the development of occupational pension plans has been limited. However, in this country, households tend to increase their personal...

Given a multi-dimensional Markov diffusion X, the Malliavin integration by parts formula provides a family of representations of the conditional expectation E[g(X 2)|X1]. The different representations are determined by some localizing functions. We discuss the problem of variance reduction...

Quelles sont les méthodes de prévision des ventes ? Comment concevoir des systèmes intégrés de prévision ? Comment les évaluer ? A ces questions Régis Bourbonnais et Jean-Claude Usunier apportent des réponses opérationnelles. Après avoir présenté les notions statistiques et...

We consider H expected utility maximizers that have to share a risky aggregate multivariate endowment X∈RN and address the following two questions: does efficient risk-sharing imply restrictions on the form of individual consumptions as a function of X ? Can one identify the individual utility...

This Bayesian modeling book is intended for practitioners and applied statisticians looking for a self-contained entry to computational Bayesian statistics. Focusing on standard statistical models and backed up by discussed real datasets available from the book website, it provides an...

In this paper we derive adaptive non-parametric rates of concentration of the posterior distributions for the density model on the class of Sobolev and Besov spaces. For this purpose, we build prior models based on wavelet or Fourier expansions of the logarithm of the density. The prior models...
