The Pareto principle is often viewed as a mild requirement compatible with a variety of value judgements.

This paper studies the problem of redistribution between individuals having different mortality rates. We use a continuous time model in which there are two types of individuals characterized by different survival probability paths. Individual preferences are represented by a generalized life...
