The theories of communicative behavior (by G.H.Mead),performative individuation (by J.Habermas) and symbolic interaction (by say,H.Blumer),from sociology and social philosophy are taken in this paper as paving a foundation for an economic model of “idea innovation”.That is the process wherein people interact with ideas/concepts within similar situation/problem solving,and the process if being able to reach an equilibrium results in a group “consensus” on the subject,which consensus then calls for a collective action by the organization/team.However,there are only a certain conditions under which the equilibria will exist.This paper proposes a set of hypoteses for the existence of the aforementioned interactive equilibria.
