摘要：El presente trabajo intenta dar cuenta de un uso distinto de la idea de homo económicus, modificando el concepto de elección racional partiendo del hecho de que las elecciones de los agentes económicos son realizadas bajo creencia racional. Se busca determinar la existencia del equilibrio de Nash en un juego psicológico.
其他摘要：The article offers a different vision of the idea of homo economicus. If in the first instance the concept corresponds with that of rational selection, what is proposed here is, the observation of behavior in economic agents, or players, who choose, according to rational belief. This last condition allows for the existence of errors in choices, and their possible correction, as part of the agents learning process; with the objective of minimizing incorrect conducts. The authors are also interested in determining the existence of Nashs equilibrium in the context of a psychological game where the agents choose according to rational belief.
