The value of information and the value of awareness

Abstract

Recent literature has examined the problem facing decision makers with bounded awareness, who may be unaware of some states of nature. A question that naturally arises here is whether a value of awareness (VOA), analogous to value of information (VOI), can be attributed to changes in awareness. In this paper, such a value is defined. It is shown that the sum VOA $$+$$ + VOI is constant and, except for scale effects, independent of the choice set. It follows that the larger is VOA, the smaller is VOI. This point is illustrated for a simple two-state case, then proved for general classes of compact convex choice sets, and for alternative interpretations of the concept of unawareness.
