[fre] Nous examinons les différentes possibilités d'estimation d'un des outils les plus utilisés en matière de gestion de risque de taux d'intérêt : la structure par terme des taux d'intérêt. Nous nous attachons plus particulièrement à la présenta­tion des méthodes fondées sur des...

Exponential smoothing (ES) with ARCH (autoregressive conditionally heteroscedastic) and GARCH (generalized ARCH) errors are introduced. This is done for a large class of ES methods, those for which the forecasts are obtained using a set of additive updating formulas, and also those for which an...

The recent financial literature has been much concerned with the short-term interest rate. Several models have been proposed and studied quite extensively. Despite the number of models, relatively little is known about their empirical comparison. A first approach of this problem is proposed in...

We present an estimation procedure for continuous time models based on discrete sampled data with a fixed unit of time between two observations. Since in general the conditional likelihood of the model cannot be derived an indirect inference procedure based on simulations of a discretized model...

The aim of this paper is the study of the path solutions of a multivariate rational expectations model. We describe several procedures for solving such dynamic systems based on either the adjoint operator method or the Smith form. As a by-product, we derive the dimension of the set of solutions...
