Dans cet article, pour etendre la theorie du consommateur a ses choix d'epargne et de placements, on utilise a la fois la theorie usuelle, celle des caracteristiques et celle du raisonnement quantitatif. On en deduit un systeme complet de demandes comprenant simultanement les quantites de biens...

This paper prepared for the Handbook of Statistics (Vol.14: "Statistical Methods in Finance"), surveys the subject of stochastic volatility. the following subjects are covered: volatility in financial markets (instantaneous volatility of asset returns, implied volatilities in option prices and...

In this paper, we provided a unifying analysis of latent variable models in finance through the concept of stochastic discount factor (SDF).

The paper investigates the pricing of derivative securities with calendar-time maturities.

Latent variable models in finance originate both from asset pricing theory and time series analysis. These two strands of literature appeal to two different concepts of latent structures, which are both useful to reduce the dimension of a statistical model specified for a multivariate time...

The paper investigates the pricing of derivative securities with calendar-time maturities.

We study the effect of an asymmetric environment on risk sharing. In our model, entrepreneurs consider undertaking risky projects in the real sector as well as selling part of their projects to investors. To capture the idea of an asymmetric environment, the returns on the alternative risk-free...

In this paper, we characterize the asymmetric of the smile through multiple leverage effects in a stochastic dynamic asset pricing framework.
