La incompatibilidad de la incertidumbre en economía con la lógica del homo economicus y con la construcción de sistemas cerrados

Abstract

The purpose of this essay is to show that the standard approach of economic modelling (which consists of assuming closed systems and optimizing agents) is ineffective for the issue of uncertainty. Since under uncertainty economic agents do not know the final outcome of a course of action, their decisions should not be represented by the process of constrained optimization. The construction of axiomatic systems that lead to the derivation of a single result is also put into question; its replacement by a simulation-based approach is proposed.
