• Frequent Turbulence? A Dynamic Copula Approach 

      Chollete, Lorán; Heinen, Andreas (Discussion paper, Working paper, 2006-07)
      How common and how persistent are turbulent periods? We address these questions by developing and applying a dynamic dependence framework. In order to answer the first question we estimate an unconditional mixture model ...
    • Modeling international financial returns with a multivariate regime switching copula 

      Chollete, Lorán; Heinen, Andreas; Valdesogo, Alfonso (Discussion paper, Working paper, 2008-03)
      In order to capture observed asymmetric dependence in international financial returns, we construct a multivariate regime-switching model of copulas. We model dependence with one Gaussian and one canonical vine copula ...
