On the Policy Implications of Changing Longevity

Our societies are witnessing a steady increase in longevity.

For that purpose, we firstly focus on some difficulties raised by risky and varying lifetime for the representation of individual and social preferences. Then, we explore some central implications of changing longevity for optimal policy making, regarding prevention against premature death, pension policies and long-term care
