摘要內容:
This paper uses the time-varying copula models to capture the mortality dependence structure across countries. Both the symmetric and asymmetric dependence structures are examined. In addition, to capture the phenomenon of a heavy tail for the multi-country mortality index, we consider not only the setting of Gaussian innovations but also non-Gaussian innovations under the Lee Carter framework model. The goodness of fit of different dynamic copula models, the pattern of mortality dependence and the distribution of the innovations are assessed using empirical mortality data for Finland, France, the Netherlands and Sweden. To understand the effect of mortality dependence on longevity derivatives, we also build a valuation framework for pricing a survivor index swap. The fair swap rates of a survivor swap are investigated numerically. We demonstrate that without using the dynamic copula mortality model and without non-Gaussian innovations, the swap rates and the loss reserves will be seriously underestimated.相關檔案:Talk_1040317.doc
