Resumen:
Many authors in the discipline as well as outsiders have claimed that the main results from MathematicalEconomics are far removed from real world phenomena. A more precise version of thisposition is that one of the main reasons for this unrealistic stance is the use of the wrong formaltools. So, for example, it has been pointed out that the computability of choice functions as wellas the existence of economic equilibria and of states of the world may not be ensured in generalif the assumed set theory is ZFC. We will show that there exists a very natural set theory thatovercomes some formal limitations of contemporary economic theory. A switch to an alternative settheory helps to obtain in a more natural way results widely accepted by mathematical economists.Moreover, alternative set-theoretical frameworks convey different intuitions about how agents behavewhen solving problems. We claim that AFA−+AD+DC is the adequate alternative set-theoreticaluniverse for economic theory.
