Intergenerational equity: sup, inf, lim sup, and lim inf

Creators: Chambers, Christopher P.

Abstract

We study the problem of intergenerational equity for utility streams and a countable set of agents. A numerical social welfare function is invariant to ordinal transformation, satisfies aweak monotonicity condition, and an invariance with respect to concatenation of utility streams if and only if it is either the sup, inf, lim sup, or lim inf.
