The Beta coefficient theorized by the CAPM is estimated by the Market Line. By hypothesis, the Beta is stable over time but empirical studies on it volatility don't confirm this fact. One of them is related to with agent heterogeneity hypothesis. In this paper; we study this hypothesis by...

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. Our approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria that can...

The market’s line estimation implicitly assumes that its parameters are constant over time. Investors, who use the beta of this line for build their portfolio, have a similar behavior whatever their investment horizon. We discuss this hypothesis in this article using the technique of wavelets...

The CAPM theory provides a measure of the sensitivity of an asset to the market called the systematic risk. The Beta of equity is estimated by its market line. According to the OLS hypothesis, it is stable over time but this is not empirically verified. Many studies are in favour with this fact...

In a Constant Proportion Portfolio Insurance (CPPI) framework, a constant risk exposure is defined by the multiple of the strategy. This article proposes an alternative conditional multiple estimation model, which is based on an autoregressive quantile regression dynamic approach. We estimate...

Cet article vise à identifier un processus non linéaire par la méthode du noyau. Cette identification nécessite une sélection rigoureuse des coefficients de Markov et le choix de la fenêtre qui détermine le degré de lissage de l’estimateur. This paper aims to identify a nonlinear...
