Speech act
In economic sociology

In a sociological perspective, Nicolas Brisset adopts the concept of speech act in order to understand how economic models participate in the making and the spreading of representations inside and outside of the scientific field. Brisset argues that models perform actions in different fields (scientific, academic, practical, and political). This multiplicity of fields induces a variety of felicity conditions and types of performed actions. This perspective is a criticism of the essentialism of philosophical modelling studies. This approach is largely inspired by the work of Pierre Bourdieu and Quentin Skinner.

In finance, it is possible to understand mathematical models as speech acts: in 2016 the notion of "financial Logos" was defined as the speech act of mathematical modelling of financial risks. The action of the financial Logos on financial practices is the framing of financial decision-making by risk modelling.
