The most well-known application of the discrete random utility theory (Domencic and McFadden, 1975) is the MNL model presented in Technical Note 2.2. One of the most popular branches in the non-EU theories is rank-dependent expected utility theory (RDEU). • IC’s can’t cross – there is one and only one IC through any point. EXPECTED UTILITY THEORY Prepared for the Handbook of Economic Methodology (J.Davis, W.Hands, and U.Maki, eds.
