This paper proposes a new empirical methodology for computing a cross-market index – coined CMI – based on the Factor DCC-model. This approach solves both problems of treating high-dimensional data and estimating time-varying conditional correlations. We provide an application to a...

In the aftermath of the 2008 financial crisis, the need to consider more realistic risk models for derivative products has received renewed attention. We introduce a dynamic model for the pricing of European-style options with various attractive features such as a mixture of heavy-tails and...

The mispricing of the deep-in-the money and deep-out-the-money generated by the Black and Scholes model is now well documented in the literature. In this paper, we discuss different option valuation models on the basis of empirical tests carry out on the French option market. We examine methods...

This paper proposes a new empirical methodology for computing a cross-market volatility index – coined CMIX – based on the Factor DCC-model, implemented on volatility surprises. This approach solves both problems of treating high-dimensional data and estimating time-varying conditional...

This article proposes a new empirical methodology for computing a cross-market volatility index - coined CMIX - based on the Factor-Dynamic Conditional Correlation (DCC) model, implemented on volatility surprises. This approach solves problems in treating high-dimensional data and estimating...

The post-crisis financial reforms address the need for systemic regulation, focused not only on individual banks but also on the whole financial system. The regulator principal objective is to set banks' capital requirements equal to international minimum standards in order to mimimise systemic...

This article brings new insights on the role played by (implied) volatility on the WTI crude oil spot price. An increase in the volatility subsequent to an increase in the oil price (i.e. inverse leverage effect) remains the dominant effect as it might reflect the fear of oil consumers to face...

Présentation d'un ensemble d'instruments financiers permettant de réduire les risques pris par l'acheteur dans une économie mondialisée. Dans l'industrie, ces outils financiers confortent l'analyse économique et stratégique des décisions d'investissement.

Cet ouvrage présente et simule les principaux modèles de volatilité et d'évaluation d'options standards avec une discussion essentiellement centrée autour du smile de volatilité. Le premier chapitre permet d'aborder les modèles de volatilité locale et implicite. Le second chapitre se...

This paper fulfills the lack of option pricing empirical studies devoted to the French market and is also the first paper that brings a comparison between the Heston (1993) closed-form solution model and the Hull and White (1988) model, built in a series expansion form. The empirical study is...
