Constructive decision theory

In most contemporary approaches to decision making under uncertainty, a problem is described by set of states and outcomes, rich acts, which are functions from outcomes over the maker (DM) has preferences. Many interesting problems, however, do not come with state space an outcome space. Indeed, in complex problems it often far clear what spaces would be. We present alternative foundation for making, primitive objects choice syntactic programs. A representation theorem proved spirit standard theorems, showing that if DM's preference relation on satisfies appropriate axioms, then there exist S states, O way interpreting as O, probability S, utility function such DM prefers b only expected higher than b. Thus, subjective, just like utility; they part description problem. principle, modeller can test SEU behaviour without having access or outcomes. illustrate power our approach capture makers who subject framing effects those failures extensionality.
