This article presents a descriptive theory for complex choice problems. In line with the bounded rationality assumption, we hypothesize that decision makers modify a complex choice into some coarse approximations, each of which is a binary lottery. We define the value of a best coarse...

In this paper, I provide a new axiomatization for rank-dependent utilities. I show that, along with weak order, dominance, and the binary rank-dependent representation, the decomposition of certainty equivalents is sufficient to derive the general rank-dependent model of Luce and Fishburn (1991,...
