ABSTRACT
This chapter explores the way in which economists regularly treat institutional facts. Developing the ontology of social entities above individual representations will make it possible to theorise the limits of theories to be performed in the social world. Exploring social ontology will also enable a consideration of the performative structural movement of the social world and its resistance to this same world during this movement. Performativity can be redefined as the implementation of social facts inspired by economic theory within a social world that can nevertheless resist this process. Performativity induces the emergence of a new convention on which agents coordinate in a world structured by other conventions. The chapter presents an analytical framework that will provide a heuristically relevant perspective on performativity given the question: why do some theories shapes social reality and others not.
