In this paper we present a reformulation of a lemma due to Lippman and McCall - initially formulated a unique random variable - to be applied to the case of several random variables, and we illustrate its use in the theory of the firm under uncertainty. We have performed this on a recent model of the theory, for which the respective optimal levels chosen by the firm with and without uncertainty are compared in a more direct way than that used originally by its authors. We also make use of the lemma, in the context of the same model, to study the effect of a variation in risk aversion, which had not been studied before.
