Between complexity of modelling and modelling of complexity: An essay on econophysics

• Distinction between “statistical econophysics” and “agent-based econophysics”.
• Clarification of emergences and complexities we can find in econophysics literature.
• Introduction to the diversity of scientific models used in econophysics.

Econophysics is an emerging field dealing with complex systems and emergent properties. A deeper analysis of themes studied by econophysicists shows that research conducted in this field can be decomposed into two different computational approaches: “statistical econophysics” and “agent-based econophysics”. This methodological scission complicates the definition of the complexity used in econophysics. Therefore, this article aims to clarify what kind of emergences and complexities we can find in econophysics in order to better understand, on one hand, the current scientific modes of reasoning this new field provides; and on the other hand, the future methodological evolution of the field.
