About
With the emergence of marginalism, economic thought was reorganized around a polarity between the subjective data that determine individual choices and the quest for models capable of representing the results of interactions between agents. I am interested in different fields of theory which make it possible to conceive the articulation between the subjective dimensions of the representation of economic agents (theories of rationality, psychological foundations, etc.). of choices, formation of beliefs and anticipations, information processing) and their aggregated consequences through social interactions (market coordination, theory, etc.). games, conventions).
