Abstract
One of the challenges related to the discursive practices of argumentative agents is to get to know if those interactions have an institutional effect. In this article, it is argued that in the new institutionalism, theoretical approaches and deterministic analysis are outlined to investigate argumentative practices that take place in processes of legitimation and recognition. Here a double socio-institutional and discursive or constructivist approach to the argumentation theory is defended, and it is argued that this perspective could be extended to a research program aimed at interpreting argumentative processes in the public sphere that act as calculation mechanism and conformation of social capital.
