This paper investigates the dependence structure between daily oil price changes and stock market returns in six GCC countries (Bahrain, Kuwait,Oman, Qatar, Saudi Arabia and United Arab Emirates) during the period from June 1, 2005 to February 11, 2013. For that, we apply three Archimedean...

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 Â…nancial crisis 2007-2009. The econometric approach is based on the extreme-value time-varying copula...

This paper proposes a new class of semiparametric generalized long memory model with FIA- PARCH errors (SEMIGARMA-FIAPARCH model) that extends the conventionnel GARMA model to incorporate nonlinear deterministic trend, in the mean equation, and to allow for time varying volatility, in the...

This paper reinvestigates the presence and the causes of the underwriting cycle in the French property-liability insurance industry as displayed by the combined ratio for the 1963-2008 period. The question is still a timely issue if we refer to regulation issues and the recent proposals in the...

This paper proposes an original framework based on nonlinear panel data models to study the empirical influence of the interest rate and the inflation rate on the non-life insurance premiums for fourteen developed countries over the period 1965-2008. More specifically, we apply the panel smooth...

In this paper, we propose a time-varying long memory model where the fractional integration parameter varies nonlinearly according to Smooth Transition Regressive (STR) model. To estimate the fractional integration parameter, we suggest a new estimation method based on wavelet approach. In...

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 financial crisis 2007-2009. The econometric approach is based on the extreme-value time-varying copula...
