We develop a model of wishful thinking that incorporates the costs and benefits of biased beliefs.

A Distributionally Robust Random Utility Model

no code implementations10 Mar 2023 David Müller, Emerson Melo, Ruben Schlotter

Second, we show that the gradient of the distributionally robust social surplus yields the choice probability vector.

On the Distributional Robustness of Finite Rational Inattention Models

no code implementations5 Aug 2022 Emerson Melo

In this paper we study a rational inattention model in environments where the decision maker faces uncertainty about the true prior distribution over states.

Learning in Random Utility Models Via Online Decision Problems

no code implementations21 Dec 2021 Emerson Melo

This paper studies the Random Utility Model (RUM) in a repeated stochastic choice situation, in which the decision maker is imperfectly informed about the payoffs of each available alternative.
