Abstract
We obtain necessary and sufficient moment conditions
for exponentiality among all class ℒ aging distributions.
This result, which solves an open problem, is derived as
a consequence of the answer to a more general question
of investigating conditions for stochastic equivalence
of Laplace ordered nonnegative r.v.'s and its ramifications.
