Published with the contribution of the Italian insurance company, INA, this volume contains the invited contributions presented at the 3rd International AFIR Colloquium. In the spirit of actuarial tradition, the colloquium paid attention to the link between the theoretical approach and the operative problems of financial markets and institutions, and insurance companies in particular. The book is thus an important reference work for students and researchers of actuarial sciences and finance, and is also recommended to practitioners with theoretical interests.
