A note on preference for flexibility. (Q1862735)

The referred paper contributes to special decision-making models in which the decisions are accepted in several consequent steps. Namely, the former result for flexibility of preferences is extended from two-period to theree-period decisions, i.e., from the preferences over sets of actual results to the preference over sets of sets of the results. In a wider sense, the results develop the methods of decision-making under uncertainty. The main result shows the effectivity of the suggested three-period decision-making process. A potential possibility to simplify the former results on two-period procedure by means of some ideas of this paper is intuitively suggested, too.
