A person that desires to maximize his/her needs or desires. Homo economicus is used most of the time to refer to the rational economic actor, who desires wealth, does not desire to work if it can be avoided, and is able to find ways achieve those ends. This assumption is accepted by many economists, especially those who follow rational choice theory, but it remains controversial. The concept of homo economicus was developed by utilitarian thinkers, and contrasts with the constructs of behavioral economics.
