In this paper we propose several models for production lot sizing for finite horizon and single quantity demands. We consider two-level inventory systems in which we take into account inventory costs for finished as well as unfinished goods. The production facility is subject to failures and...

We examine asset pricing models with time-varying betas.

We prove that...
