This article adopts the asymmetric DCC with one exogenous variable (ADCCX) model developed by Vargas (2008), by updating the concept of ‘volatility surprise’ to capture cross-market relationships. Current methods for measuring spillovers do not focus on volatility interactions, and neglect...

L’étude analyse les principaux déterminants du taux de change réel et modélise les effets de la politique de change du Cameroun sur ses équilibres externe et interne. Après une brève revue de la littérature sur les travaux sur les taux de change réel. Les techniques d’analyse de la...

This paper examines jointly the empirical relevance of the mean-reversion and the PPP hypotheses in the exchange rate dynamics under the EMS. Given the non-stationarity and the non-linearities characterizing the foreign exchange rate dynamics, this question is studied using a MS-ECM model: it...

The present article provides an unorthodox model exchange rate dynamics based on conventions that prevail among market participants. We build a theoretical model that highlights the mechanisms underlying the formation of market conventions. We then test this model empirically on the euro/dollar...

To assess how financial markets and commodities are inter-related, this paper introduces a ‘volatility surprise’ component into the asymmetric DCC with one exogenous variable (ADCCX) framework. We develop an econometric model in which returns and volatility allow to influence pairs of...

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...

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...

Three processes reflecting persistence of volatility are initially formulated by evaluating three Lévy processes at a time change given by the integral of a mean-reverting square root process. The model for the mean-reverting time change is then generalized to include non-Gaussian models that...

This paper studies the nonlinear adjustment between industrial production and carbon prices – coined as ‘the carbon-macroeconomy relationship’ – in the EU 27. We model carbon price returns and industrial production as nonlinear and state-dependent, with dynamics depending on the sign and...
