Sacha Bourgeois-Gironde has worked at the interface of economics, philosophy, and cognitive sciences. His recent work aims at uncovering the minimal cognitive conditions compatible with the emergence and stabilization of complex social and economic institutions. In that perspective, he has published several articles in major journals on the nature of money; one of his main research topics. Notably, he has evidenced, in the lab, proto-monetary behaviors among capuchin monkeys.
Behavioral decision theory, game theory, and mechanism design, constitute the formal and theoretical background of his approach to institutions, which is also experimental and, more recently, field-oriented.

In the next five years, Sacha Bourgeois-Gironde will pursue his work along three main directions:

- The exploration of homeomorphic models in decision-theory. Namely a formal model of preferences and beliefs should, as far and as parsimoniously as possible, incorporate realistic features and processes of the mind it models. His 2019 book "The Mind under the Axioms" spells out this position.

- The investigation of the interface between bounded minds and their economic, social, and ecological environments. Minimal cognition compatible with the maintenance of institutions (such as public goods) will be explored in the same vein as before, but also approached from the perspective of its legal codification and interpretation. One main instance of this topic will be the monographic study of a New-Zealander/Maori river having acquired the legal status of a living being.

- Language and economics. Linguistic interactions can be modelled using economic tools. But the main focus of Sacha Bourgeois-Gironde’s project in this field is to understand how language affects economic behavior, cognition, and organization: whether linguistic differences have some influence on economic behavior; in which way linguistic barriers affect cooperation, competition, or growth. At the individual level, the core theoretical idea is to substitute to exogenous axioms of rationality on preferences, internal psycholinguistic constraints influencing behavior.
