چکیده

This paper examines the dynamic dependence between American and four developed stock markets, namely, Japan, United Kingdom, Germany and France during a recent period including the global …nancial crisis 2007-2009. The econometric approach is based on the extreme-value time-varying copula functions. Speci…cally, the marginal distributions are reproduced by an extreme-value based model while the joint distribution is explored using time-varying Normal and SJC copulas. The empirical results show that the dynamic dependence between American and Japanese stock markets is symmetric while that between American and European stock markets is asymmetric. In particular, this dependence seems to be related to geographic position. Keywords: dependence, stock markets, extreme value theory, time-varing copulas. Résumé: Ce papier examine la dépendance dynamique entre le marché des actions américain et ceux de quatre pays développés, à savoir , le Japon, le Royaume-Uni, l’Allemagne et la France au cours d’une période récente qui inclut la crise …nancière mondiale de 2007-2009. L’approche économétrique repose sur les fonctions copules basés sur les valeurs extrêmes et variables dans le temps. Plus précisément, les distributions marginales sont reproduites par un modèle basé sur les valeurs extrêmes alors que la distribution conjointe est explorée à l’aide des copules normales et SJC variables dans le temps. Les résultats empiriques montrent que la dépendance dynamique entre le marché des actions américain et japonais est symétrique alors que celle entre le marchés des actions américain et européen est asymétrique. En particulier, cette dépendance semble être liée à la position géographique. Mots-clés: dépendance dynamique, le marché des actions, la théorie des valeurs extrêmes , copules variables dans le temps.

Commodity and equity markets: Some stylized facts from a copula approach

In this paper, we propose to identify the dependence structure that exists between returns on equity and commodity futures and its development over the past 20 years. The key point is that we do not impose any dependence structure, but let the data select it. To do so, we model the dependence between commodity (metal, agriculture and energy) and stock markets using a flexible approach that allo...

A Copula Based GARCH Dependence Model of Shanghai and Shenzhen Stock Markets

Copula is a function which can link two or more marginal distributions together to form a joint distribution. This paper aims to analyze the dependence between Shanghai and Shenzhen stock markets using copula theory based on GARCH. We use the synchronous 100 times daily returns data and copula based GARCH to model the joint distribution of stock index returns because copula based GARCH can fit ...

Time-varying Extreme Value Dependence with Application to Leading European Stock Markets

Extremal dependence between international stock markets is of particular interest in today’s global financial landscape. However, previous studies have shown this dependence is not necessarily stationary over time. We concern ourselves with modeling extreme value dependence when that dependence is changing over time, or other suitable covariate. Working within a framework of asymptotic dependen...
