Abstract
A comparison of two upper bounds for the tails of compound distributio ns, both defined in terms of a new worse than used (NWU) distribution, reveals that one is sharper in the decreasing failure rate (DFR) case . An inductive argument is employed to construct a lower bound in term s of a new better than used (NBU) distribution which is a dual to the upper bound. It is also sharper than the corresponding lower bound in the increasing failure rate (IFR) case. Applications to ruin theory ar e then given.
