EUAs are European Union Allowances traded on the EU Emissions Trading Scheme (EU ETS), while Certified Emissions Reductions (CERs) arise from the Clean Development Mechanism under the Kyoto Protocol. These emissions assets attract an increasing attention among brokers, investors and operators on...

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...

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...

The article discusses the views of statistics professors Andrew Gelman and Christian P. Robert about the intemperate anti-Bayesian statement appeared on the book of probability theory by mathematician William Feller. It notes that they explore Feller's words along with similar remarks by others...

The missionary zeal of many Bayesians of old has been matched, in the other direction, by an attitude among some theoreticians that Bayesian methods were absurd—not merely misguided but obviously wrong in principle. We consider several examples, beginning with Feller's classic text on...

We consider finite state space stationary hidden Markov models (HMMs) in the situation where the number of hidden states is unknown. We provide a frequentist asymptotic evaluation of Bayesian analysis methods. Our main result gives posterior concentration rates for the marginal densities, that...
