This paper addresses the issue of intergenerational and internationalsharing of longevity and growth risks. Current research on worldwidedemographic changes highlights the importance of longevity risk on financialmarkets and the need to devise optimal hedging vehicles. We present a...

We consider an homogeneous class of assets, whose returns are driven by an unobservablefactor. We derive approximated prediction and pricing formulas for the future factorvalues and their proxies, when the size n of the class is large. Up to order 1=n, these approximationsinvolve solely...

We consider the modelling of credit migration risk and the pricing of migrationderivatives. To construct a Point-in-Time (PIT) rating migration matrix as the underlyingvalue for derivative pricing we show first that the Affine Markov Chain models isnot sufficient to generate PIT migration...
