La preferencia revelada frente al enfoque utilitarista: discusión sobre los fundamentos de la teoría del consumidor

This article makes a critical comparison of two approaches to the foundations of the microeconomic theory of consumer behavior, namely: the utilitarian approach and that of the revealed preference theory. An analysis of revealed preference is carried out in the context of introducing restrictions to the choice function in decision theory. Its advantages and limitations are evaluated in contrast to the utility problem proper to the subjectivist point of view of utilitarian theory. And the explanatory capacity of the different models of rational agency is confronted on the bases of the demand curves. Furthermore, a formal critique of the revealed preference method is developed in strategic decision-making environments.
