Expected Utility and Its Discontents. The Marshallian utility theory ignores complements and substitutes of the commodity under consideration. We contrast three decisions rules that extend Expected Utility to contexts where a convex set of probabilities is used to depict uncertainty: T-Maximin, Maximality, and E-admissibility.The rules extend Expected Utility theory as they require that an option is inadmissible if there is another that carries greater expected utility for each probability in a (closed) convex set. They proposed that when we make decisions this is what we do. PT states that people take gains and losses differently, and that those differences affect their behaviors differently. Expected utility theory is a model that represents preference over risky objects, by weighted average of utility assigned to each possible outcome, where the weights are the probability of each outcome.

The expected utility theory then says if the axioms provided by von Neumann-Morgenstern are satisfied, then the individuals behave as if they were trying to maximize the expected utility. We contrast three decision rules that extend Expected Utility to contexts where a convex set of probabilities is used to depict uncertainty: Γ-Maximin, Maximality, and E-admissibility.
