Abstract
The theory of rational choice involves several aspects, which I chose to present especially in highlighting the impact it has on economic agents. The issue I have chosen to address in this paper concerns how rational decisions that impact on available resources should be made at a given time. Man from the perspective of the economic agent expresses economic rationality in situations of all kinds of constraints, in other words, he realizes the importance of some resources when economic imbalances manifest negatively on the economic agent. The notion of homo oeconomicus has evolved over time depending on the economic realities at the time, whether we refer to the classical or neoclassical period, being essentially the expression of the theory of rational economic choice. Rationality is a permanent trait of human being, but at the same time it can also have better results while implemented in a context.
