The entropy principle yields, for a given set moments, a density that involves the smallest amount of prior information. We first show how entropy densities may be constructed in a numerically efficient way as the minimization of a potential. Next, for the case where the first four moments are...

Recent portfolio choice asset pricing and option valuation models highlight the importance of skewness and kurtosis. Since skewness and kurtosis are related to extreme variations they are also important for Value-at-Risk measurements. Our framework builds on a GARCH model with a condi-tional...

In order to analyse the interest rate transmission mechanism, we study daily Euro-rates term structure for the US, Germany, and the UK between 1983 and 1997. We estimate multivariate VECM-GARCH models, which takes into account most of the usual feaures of financial data (non-stationarity,...

Nous etudions dans ce papier la relation entre le rendement et le risque pour les marches de taux sur l'euro-dollar, l'euro-mark et l'euro-franc, de 1975 a 1997. Nous testons la relation entre l'exces de rendement de portage et la volatilite a partir d'une modelisation ARCH-in-Mean.

En nous inspirant des travaux portant sur les marches boursiers des pays industrialises, nous analysons la volatilite des rendements boursiers d'Asie du Sud-Est a partir de la methodologie ARCH. Notre objectif consiste a mettre en evidence les specificites des marches boursiers du Sud-Est...
