Elecciones racionales ¿utopía?

Abstract

Individuals are constantly making decisions, which in many cases can present coordination and information failures. It is important to ask whether individuals always present that optimal and maximizing behavior in their decisions, characteristic aspects of the theory of rationality. The objective of this article is to determine, from authors such as McFadden, Woodford, Kahneman, Sims, whether individuals still make decisions based on rationality, or on the contrary, if rationality today is considered as a utopia. To determine this, an exploratory qualitative analysis was made of the main theories that have been developed in this field in recent years. Among the results, it is worth mentioning that despite the fact that much progress has been made in formulating models that better explain the agents' decisions, it is clear that this has not been enough. McFadden's Theory of Prospective can not generate economic implications, because the individuals who make arbitrary decisions are limited in the markets. While in the theory of Random Attention developed by Sims and adopted by Woodford, individuals have finite capacity for information processing.
