Homo economicus

Homo Economicus is the theoretical portrait of a human who is consistently rational and self-interested. The main motive of all transactions and actions are deriving from rational egoism (D. A. Urbina and A. Ruiz-Villaverde, 2019). The term homo economicus comes from the combination of two other terms - homo sapiens (humans) and economics. Homo economicus can also be understood as economic man. The concept of homo economicus is highly discussed in economics, sociology, psychology and antropology studies. In economics, the concept of economic man is often discussed together with profit-maximisation (the theory of the firm), utility maximisation (consumer choice) and theorems of welfare (D. A. Urbina and A. Ruiz-Villaverde, 2019).

Homo economicus

The term Homo economicus was first used by John Stuart Mill, who described man "as a being who desires to possess wealth, and who is capable of judging the comparative efficacy of means for obtaining that end" (D. A. Urbina and A. Ruiz-Villaverde, 2019). Later it has been argued that the concept of homo economicus is not only about wealth and luxury; however, it can be applied to many other situations and cases.

Homo economicus is described as a human, who has predetrmined motives to maximise the gain and secure the greatest value from economic interactions, and activities they have. This gain or maximised value is not always charactersied by money, or wealth. This self-interest is part of everyday life of homo economicus. When an economic man meets another person for an economic interaction, homo economicus will assume that egoism and greed are the feeling driving that person. Although, the impression about someone can be changed after some time, the frist opinion of homo economicus about a partner is always judjed from egoism perspective (G. Ailon, 2020).

It is broadly discussed which anatomical systems might lead to homo economicus behaviour in a human. The two systems that might impact the way a person behaves are:

• Cognitive system;
• Emotional system.

Cognitive system is responsible for existing knowledge and discovering new knowledge. It encompasses functions that support rational behaviour, such as calculations, self-control, analysing, forward-looking. Emotional system in the same time is more connected with irrational behviour. Emotional system is attributed with empathy, lack of self-control, actioning prior to analysis and myopicy. It can be seen that cognitive systems are more related to rational bahviour and hence homo economicus than emotional system (L. Leonard, 2006).

Describing homo economicus

Homo economicus can be descirbed as:

• Practical, rational and self-interested human.
• In psychology Machiavellian personality can be also homo economicus, as these two terms have lots in common.
• Homo economicus is a theoretical portrait of a rational human. Modern behavioural economists believe that humans are not rational in their decision-making.
• Cognitive or emotional systems might be responsible for the level to which the person is human economicus.
